The world's longest concrete pump truck boom staged the first show

July 28, the Guinness Book of World Records the world's longest boom pump - Zoomlion 101 meters of carbon fiber boom pump in the "Central China's tallest building," the first show in Wuhan center construction. The collection of the carbon fiber boom pump structure section seven arm technology boom vibration control technology and motor coordination, the most cutting-edge technology to develop a series of pump field a full operational loads analog design analysis technology, and efficient large displacement technology . Its success construction, representing Zoomlion for long boom pump technology giants to master and use environment, and establish a benchmark for the global truck products. The field of construction machinery called "the most luxurious performance" construction exhibition, which attracted more than experts in the field, the construction machinery industry association leaders and hundreds of domestic construction machinery end users.

Steel Jubi volley pumped change my life scared Mining
Four o'clock in the afternoon, 101 m truck debut in Wuhan, central site opened. Viewed from the Wuhan center podium, I saw a steady flow of steel Jubi concrete delivered to the top of the Wuhan center on the 4th floor of the main building, spectacular scenes.
As the saying goes, "lay watch, experts see Road", from the construction of three of the "experts" - the construction site for the Project Manager Deng Weihua correspondent interpretation of the 101 meters Aspect pump construction: "The construction wonderful place can be summarized by three words, that is 'long', 'stable', 'fast' 'long' refers to the 101 m pump in extreme conditions to achieve a normal length boom pump can not be achieved Long span pumping, 'stable' refers 101 meters the world's longest boom pump stability in the construction process even more than the general short boom pump, 'fast' refers to the 101 m pump Concrete pumping efficiency can reach 60 m pump of 1.36 times. "
Reporters learned that the late 1960s, German invention 16 m boom pump, and spent nearly 20 years to nearly 40 m jib hoist, after the development process will be the length of the boom truck was stalled. Until the twenty-first century, the situation was only China's "latecomers" rewrite. In recent years, due to the continuous development of China's long arm pump technology, the domestic market demand and the structure has been quietly changed. Among them, in the weight proportion Chief boom pump truck it sells products from about 30% three years ago, it rose to around the current 60%. As long arm pump technology pioneer, leads the way, Zoomlion research team mastered the technology in the field of patents hundreds pump successfully developed to 80 m, 101 m of carbon fiber boom pump as the representative a series of long arm pump. Secretary-General of China Construction Machinery Industry Association, Suzi Meng description: "The production of Zoomlion 101 meters of construction and truck series long arm pump, indicating to Zoomlion, led by our long arm pump technology has gone a world leader in science and technology innovation capacity Zoomlion led to the development and progress of similar products, but also reflects China's manufacturing industry by leaps and bounds. "This not only benefited originated Zoomlion research institutes of science and technology innovation enterprises genes, and also Zoomlion become the first brand of engineering machinery pursue inseparable.
Open blue ocean very close to the world's top three
A Societe Generale Securities ten main financial indicators for the construction machinery industry listed companies in 2012 and the first quarter of 2013. Analysis of data shows: total industry revenues since the first quarter of last year fell, a decline in the fourth quarter of last year reached maximum 86.8% Then in the first quarter to close to 55%. Data transfer of such a message: industry revenues continued to decline year on year high. Data outlines the construction machinery industry is facing a winter situation, but also reveals the industry increasingly fierce market competition.
Faced with tough competition in the market and the recent chaos of the outside world public opinion, as the head of Zoomlion concrete machinery business, the core business of non-Chen showed a strong confidence in the future. He believes that the more companies in a difficult situation, the more it should sink in the heart to do practical things, rational face of competition. He said that although the industry is facing overcapacity, slowdown of winter, but as long as good at seizing future trends, see new growth, and the ability to develop new areas of the corresponding products through technological innovation, the future of concrete machinery industry is still promising.
In recent years, Zoomlion concrete machinery company will continue to sand equipment, dry mortar equipment, continuous gradation mixing plant and other new products to market. Reporter has learned that China has nearly 3 billion cubic meters of concrete per year for infrastructure and major construction projects, it is estimated that the concrete industry is now growing at a rate of nearly 10 billion tons of annual consumption of sand and gravel, river sand mining for many years brought wanton the growing scarcity of natural resources river sand, concrete cost of raw materials prices continue to rise and other issues. Zoomlion introduced to the market mechanism sand equipment can use construction waste and other raw materials in the production of sand substitute for river sand, become the upgrading of the quality of sand and gravel, river sand resources protection, construction waste processing more efficient solutions. Experts predict that the market will increase the proportion of sand every year. The next decade efficient, environmentally friendly new sand equipment reached nearly billion annual market demand.
Ready-mixed mortar can be widely used in the construction a new building material, in European and American countries have developed more mature. With the continuous development of China's environmental protection cause, following the commercial concrete widely available, countries have began to further promote the ready-mixed mortar. Zoomlion early in 2007 set about developing dry mortar equipment, to achieve the independent development of core components, the introduction of products on the market leader. According to expert estimates, the future size of the market ready-mixed mortar capacity of up to 5-8 million tons. To 2015-2017, the ready-mixed mortar production line annual sales of up to about 1200, the annual sales volume of ready-mixed mortar equipment up to 20 billion, has a promising future.
Graded concrete mixing plant is Zoomlion concrete industry for the production process problems, tailored a solution. According to reports, the use of continuous gradation produced concrete mixing floor, not only can save cement per cubic meter of concrete with about 50-100 kg, and produced concrete strength will be significantly better than similar products, thereby greatly enhancing the reinforced concrete structures life. And extend the life of the building, it is the best measure of a low-carbon economy.
Non-Chen said that the future of concrete machinery industry needs products will be more environmentally friendly, intelligent, user-friendly products, with the above-mentioned security technology and products in the industry, he was confident of emerging markets and now the same scale reconstruction of a concrete machinery industry cluster .
Chen Non-introduced Road, in 2012, after the 2013 first quarter results with the industry overall decline since the second quarter Zoomlion concrete machinery sales presentation qoq trend. Due to prudent management style, product technology to meet market continued innovation, business performance steadily. In addition, the chairman of Zoomlion Zhan has also showed that: the future, in addition to construction machinery industry, Zoomlion also planned environmental industry, agricultural machinery, heavy trucks, financial services and other business four business segments, shows among the "top three global engineering machinery enterprises' confidence and determination.

OTR tire maintenance tips and precautions

According to statistics, maintenance costs, vehicle tires accounted for the entire 15% of the cost of normal maintenance. Analysis of abnormal wear of the tire causes and take appropriate measures to prevent abnormal tire wear and prolong life, reduce costs and improve efficiency in the use and ensure the safety of their jobs and others have practical significance.
Tires are an important part of the wheel of the vehicle, its technical condition directly affects the traction of wheeled vehicles, by nature, smooth, safety, comfort and economy. According to statistics, maintenance costs, vehicle tires accounted for the entire 15% of the cost of normal maintenance. Analysis of abnormal wear of the tire causes and take appropriate measures to prevent abnormal tire wear and prolong life, reduce costs and improve efficiency in the use and ensure the safety of their jobs and others have practical significance. By analyzing the reasons for abnormal wear of the tire, it puts forward a number of measures to extend the useful life of tires, for user reference you practice in order to save costs, protect the machine, to get better value for money.
Abnormal wear of the tire during use caused due to various factors, it is to make the majority of drivers headache. There are tire pressure is too high, too low, overload operation, poor wheel alignment, as well as rough handling operator driving unskilled caused unreasonable damage as well as an optional external hard objects and installation of tires, will be to reduce the tire life. How to effectively circumvent these abnormal wear, we need to do the following in these areas:
First, strict adherence to standard tire, inflated should check all parts for leaks, and tire pressure should be checked regularly to ensure compliance with standards. To develop the habit of using a barometer measuring the pressure, do not judge with the naked eye. To ensure that the tires have a certain flexibility, at a predetermined load to bear, so that deformation does not exceed the specified range, ensure the vehicle has good stability and comfort while in motion. Spare tire air pressure to charge relatively high, so as not to run gas falling.
Secondly, we must properly matching and installation of tires, according to tire size equipped with the appropriate tube. Tires on the same mechanical assembly shall ensure that the same brand, the same structure and the same performance. If this is not done, it should be on the same shaft assembly of the same brand, same size, the same pattern and the same type of tire; when new tires, should be done with the vehicle or coaxial transducer; with directional tread tires shall be installed in accordance with the provisions of the rolling direction; when switching to new tires, new tires should be mounted on the front wheel, repaired tire is mounted on the rear wheel. To ensure traffic safety, retreaded tires are not allowed to make the steering wheel (front) use.
Third, regularly rotate the tires. After the vehicle for some time, before and after fatigue and tire wear on it is different, and should therefore be required to timely transposition. There are two methods to change a tire cross and round-robin. Transposition law applicable to the regular on the arch of a larger road vehicles, while the law applicable to the regular cycle of change on a relatively flat road vehicles.
Fourth, as well as control tire temperature, vehicles in the process, the tire due to friction, deformation of the heat, so that the temperature inside the tire, the pressure increases. When the tire temperature is high, the buck can not use deflate method, but not to the tires cool splash avoid accelerated tire damage. Should shady place to park at rest, before continuing with the tire until the temperature decreases. The way the vehicle is stopped and the site, to develop safe taxi parking habits. To select a smooth, clean and free of grease ground parking, each tire must be smooth landing, especially vehicle loading overnight, but also should pay attention to selecting the parking place, if necessary, from the top to the rear wheels. When the vehicle is a long time out, you should use the wood to the frame to withstand in order to reduce the load on the tire; not no place to park the tire pressure should be from the top wheel.
Fifth, tires should be stored in the vicinity of the sun to avoid, oils, acids, flammable and corrosive chemicals. All tires should be stored in cooling, dry and dark interior, tires should stand up, non-flat, stacked or hung heart strings. Storage period shall not exceed three years. For separate storage tube should be filled with the right amount of air can not be folded flat or stacked. When not stored separately, they need to be placed within the tire, and the right amount of inflated.
In addition, in the winter cold area, due to the low temperatures, the tire rubber brittleness increased, decreased flexibility, again with a vehicle parked overnight or for a long time after, the start should slowly lift the clutch pedal with a smooth start, the first few kilometers to low speed, be tire temperature rise after normal driving. If the vehicle is suspended on the ice for some time, the ground site may be frozen at the start should be particularly careful to prevent tread tearing. The vehicle is cold outdoor parking area for a long time, in order to prevent the tires and the ground frozen, should be fitted wood or sand in the tires.

What dust technology of the dust precipitator is?

Dust removal equipment manufacturers to share technology in the "dust" generally refers to what?

We know that dust technology multiphase mixture of gas and dust collection system separation technique, but also to control particulate pollutants, solid particles are not necessarily limited to, but can also be a liquid.

Substance multiphase mixture in a dispersed state is called the dispersed phase or dispersed substances, collectively referred to as dust or dust collection system, and the other is called the disperse phase material surrounded by connecting phase or dispersing medium, such as a gas or a liquid.

As the object of dust removal diameter (particle diameter for short), generally between 0.01-100um, 100um or more dust collection system will fall by gravity away quickly, the object does not become a dust, 10um or more dust collection system more easily separated and removed , 0.01-10um dust collection system, especially dust 1um particle separation more difficult or less, is harmful to human health, and therefore should be noted that the particle size of dust to be suitably selected filter.

What are the construction technology of concrete material?

concrete mixing boom pump into rural housing choice of concrete machinery

Rural housing or manual agitation? Small commodity floor, township building still blender or mixer plus add ivy concrete mixing boom pump? There are mined, road and rail tunnels, water conservancy and hydropower engineering, slope control geological disasters, infrastructure and irrigation concrete pouring What are the concrete equipment used for?Is concrete mixing boom pump? Car pump? Pump? But these types of equipment are required to cooperate with other construction equipment. Suppliers such as mixers or concrete trucks, but suppliers of concrete is more expensive, no doubt cost will be greatly increased. Then there is no cost savings, concrete mixing quality can be achieved mixed standard equipment suppliers do. Yes, that is stirring concrete mixing boom pump, if you have not heard, then you are OUT.

Why would you OUT, because stirring concrete mixing boom pump since Sanmin heavy promotion division, was quickly known in the industry, peer imitate springing up, we can imagine the impact and the impact on the market, the most important is to meet the customer's needs. Sanmin heavy branches stirred concrete mixing boom pump occupy a certain market share, with brand awareness, due to its functional advantages and services for our customers save time, effort and money. All along, the construction of China's rural areas, the use of manual mode, or semi-mechanical mode, long duration, high cost and poor quality. In recent years, he engaged in heavy manual labor less and less well-paid construction workers hard to find, resulting in slow construction progress in rural areas, the high cost. Construction generally is manual mixing or blender add ivy, but stirred concrete mixing boom pump construction operating system used in all automation, set the material, mixing, high pressure pumping into one. Simple operation, stable performance, widely used in various construction machinery in the fine aggregate concrete for small and medium, stirring and conveying foundation to fight Zhuang large aggregate concrete. Especially suitable for rural civil construction, towns and rural construction, small high-rise construction, mine, road and rail tunnels and other cave construction, water conservancy and hydropower engineering, slope control geological disasters, infrastructure and irrigation concrete pouring large or narrow space, etc. Construction site.Sanmin heavy division is the first large-scale research and development, production, promotion stirred concrete mixing boom pump enterprises, with a number of relevant national patent certificate, not only technology is more mature, and an exclusive first developed the twin-shaft compulsory mixing stirring concrete mixing boom pump,concrete mixing boom pump. Stirred by the roller concrete mixing boom pump to compulsory concrete mixing boom pump vehicle then concrete mixing boom pump, Sanmin heavy division has been an industry leader status.Both can be concrete mixing boom pump stirring stirring, a device equivalent to two devices, the cost savings on undoubtedly the first choice. And efficient use of up to 4 to 6 times that of traditional fixed mixers and concrete pumps, stirring and pumping process, two processes have been required only one operator is completed, construction can save 3 to 4 employees, reduce costs. Mixing concrete of good quality, high efficiency, high degree of automation, easy to move flexible, powerful motor performance, very suitable for multi-site operating alternately removed. Besides stirring concrete mixing boom pump price is not expensive, cheaper than buying concrete mixing boom pump plus mixer prices. Buy low-risk, cost recovery period is short, both to their own contracting business, but also rent rich. Building as a building 300 square, just 80 minutes you can complete the construction. Is not very cattle. Such stirring concrete mixing boom pump you really heard it, it is not really OUT of it.

Scissor lift energy-efficient hydraulic system design scheme

Scissor lifts are in mine construction, mine maintenance and coal transportation more an application handling equipment. It mainly consists of the load almost Desk, sting fork support thumb member base and hydraulic system, etc., work by hydraulic pressure of the hydraulic cylinder output drive rod and the scissor work platform, and achieve a variety of control by the crossing through the system and protection. In the elevator rises when carrying heavy loads. To provide the driving force of the hydraulic cylinder, hydraulic flesh sunglasses lose volume, the rolling clamor foot (taxes mechanical energy) into the gravitational potential energy: while in the lift when the emphasis was to bring down the gravitational potential energy will be released to flooded. This gravitational potential energy efficiency built without lute clothes recycling will result in waste of energy. If you set the energy storage device in the hydraulic system of the machine. The decline can be released during the lift out of the gravitational potential energy stored. And when it rises into hydraulic energy, it can be reused, reducing energy consumption, improve the efficiency of the hydraulic system.

Hydraulic System Design and Analysis

Crossing atrophy system must be able to achieve the lift wells, drop, speed, stay, overload protection and can limp recovery and other functions. And love to seek simple, efficient sea, smooth running, working clap rely on, according to the design of the hydraulic system shown in Figure 1. The system uses accumulators recovery potential, in order to reduce internal leakage from the direction of the valve caused by Cheng lifts slowly sinking dip. With a good two-way valve seal control cylinder direction. Using accumulator recovery potential, its principle is: the elevator descent, the lift cylinder rod chamber towel generated by gravity pressure fluid is discharged into the accumulator, the mechanical potential energy is converted into hydraulic energy. Bear and stored in the accumulator vessel; rise in the potential drop over again Ji Taiwan, the accumulator to the hydraulic oil (equivalent to set up a pressure tank in the system), reduced splash pump, the oil pressure in the foot difference. The ascending process of the pump motor power consumption decreases again. To save energy. Because the lift only apparent movement in the vertical direction. Its decline can be realized by means of gravity, in order to simplify the structure of the fuel tank, lower manufacturing costs, the use of a single-acting cylinders, two cylinders in parallel; the direction of movement of the cylinder valve lO Bo direction control; to improve the two cylinders synchronization accuracy. Using a synchronous circuit by the sub-Luk consisting of a flow valve; to achieve rapid decline set up two two-way tie 7: For the output flow of the pump depression secret teach breaking traffic towards adaptation needs to improve the efficiency of the system, using a formula variable volume by the limited pressure pump drive throttle leaf hairpin tie consisting of a vortex throttle speed ring road: the output pressure of the pump depending on the load, the relief valve 4 is used for system safety valve, relief valve 9 to Bute limit the maximum pressure accumulator when the check valve 6 to lift rises to the highest position. After the pump shut down, closed the lift cylinder rodless Qu, the lift station bears a long time to stay in the work place cook; single melt valve 16 (valve clear sign for the back) for the holding certain minimum pressure in the accumulator, needs work properly. All these considerations designed hydraulic system, management of work processes and principles of the hydraulic system for analysis: force the oil, start the pump 3-way tie decorated l, help tank suction filter 2, then through the throttle valve 5, single the valve 6, two-way valve 10 is a right position and shunt flow valve lift oil into the King ll rodless chamber, the piston law Gu Ping, driving scissors stalk, pushing down the stage show, dance, lift grasshopper velocity The size can be controlled throttle 5.
After the stop ring in a predetermined position of the lifting platform to rise, so that the pump antimony grapes. No thumb Kui Medical rolling short dance drop mandarin duck stuffed produce enzymes vertical force weight oil is a reliable one-way valve 6 closed, lifts can reliably remain in a predetermined position.

The two-way drop Tian Bei of Shu lO l ¥ A magnet is energized to switch to the left position, the cylinder rod chamber of a fluid through the shunt flow valve 11 and the check valve 8 into the accumulator 14. pressure liquid is stored in the accumulator vessel bears. Li l to examine fluid accumulator Yao force, it is filled with the gradual rise. To lift fell over to the braking action. So smooth lowering speed lifts: 3 and because the pump outlet is closed, one-way Min 16 Although dance can express, the pump can not operate as a motor condition Li Li cluster inhalation solution; single trader valve l Because I din inch Dogs on the pressure chamber at chamber also turned off, so that when the elevator fell, hydraulic cylinder rod chamber of the discharged hydraulic oil will not enter the cloud nationals, two are foot-l poison into the reservoir, will be able to ferry Peng Chu Jalan mining deposit.

Rapid decline in emergency circumstances require rapid decline, it can be switched on the electromagnet lYA and 2YA. So that the cylinder rod chamber of fluid through the shunt a set Luk tie l, two-way left-bit mi lO tattoo two two-way valve 7 is turned to the left position lanthanum box, eliminating explain oil resistance, lifts and achieve rapid decline. 8 vend check valve prevents the fluid transducer at this point by the two two-way valve 7 filter nursery tank to store cents sputum still some pressure oil.

Rising again make two-way solenoid valve 10 lYA loss of power. Hydraulic pump 3 to draw lightning stupid some pressure fluid from the accumulator Han (this breed provider of valve l in Guinea is under pressure accumulator oil off), and then by the throttle valve 5 check valve 6, two three lO and diverter valve in case of a flow valve ll into the lift cylinder rodless dirty hoe up soil around plants Cuan desolate piston, rod drive scissor dance, ballad Beng male grasshopper rise moving boat down, lifts the moving speed of the 5 throttle control. Since the suction pump 3 is a certain pressure of the oil. Import and export pressure Mino reduced consumption of Fen Chan Yi cents engine power will be reduced. Ai-chan from real energy conservation, improve the efficiency of energy use. If the lift height is greater than the initial rise again ascent or leak due Cheng is willing to make the reservoir due to foot-l stone roller Polo stupid insufficient amount of oil stored in the hydraulic pump 3 through the check valve l oil from the reservoir.
