Buy concrete pump method

Starting from the technical parameters Typically, a concrete pump has the following main technical parameters: transport emissions, the outlet pressure, electrical power and distribution valves form. In accordance with the new national standards, which several key parameters from the concrete model of the pump can be learned. The following concrete pump "HBT60-16-110S" concrete pump as an example of their representatives significance
HB-- concrete pump pinyin abbreviation
T-- towed
S-- dispensing valve for the S-shaped swing pipe valve
60-- maximum transport capacity, m3 / h
16 ---- concrete conveying the maximum pressure at the pump outlet, MPa
110-- motor power, kW
Marked according to the outlet pressure rating, is divided into a low pressure pump (≤5MPa), the pump (6-10MPs) and high-pressure pump (> 10MPa); according to the maximum throughput per hour, there are 20-100m3 range, and large Most concrete pump can achieve two tranches of variable displacement or stepless variable. Users should be based on the actual needs of the project, according to the height of transmission distance and choose the outlet pressure; according to the ability to feed stirring, the choice of the output side volume; according to pumping concrete aggregate situation, choose the form of the dispensing valve. S-shaped swing pipe valve pressure loss during pumping, smooth concrete flow channel, but by limiting the diameter of a higher aggregate requirements, suitable for medium and high-pressure pump, suitable for high-rise buildings and concrete quality long-distance, high-lift transport; gate valve because of low demand for aggregate is 'eat whole grains' has said that the medium-pressure pumps used more often, pumping height of 100 meters, 300 meters level.
Starting from the motor power
A concrete pump motor power is to determine the amount of outlet pressure and delivery side a prerequisite under motor power in certain circumstances, increase the amount of pressure will make the delivery reduced; on the contrary, reducing the outlet pressure will make the delivery quantity increase. In order to ensure concrete pumps both have a larger throughput, but also a certain outlet pressure and the matching of economic power in the concrete pump's design, mostly using a constant power piston pump; that is constant power value Once selected, when the outlet pressure increases, the pump displacement volume is reduced automatically reach and power to design corresponding value; if necessary to achieve the outlet pressure is high, but also want the purpose of transmission capacity. The only way is to increase the motor power. Therefore, in the new national standards, citing the ability to index concept concrete pump (in MPa · m3 / h as the unit of measure); that is the actual pump delivery pressure and the amount of the actual export of concrete per hour, good product, the value, the more large, the greater its ability index, the greater the electrical power will, thus achieving large displacement, high lift purposes. I am in the design, functional design also uses a high voltage switch to meet the different construction requirements, economic status, but also have a greater transport capacity, or in the same motor power, resulting in a higher outlet pressure .
