Maintenance knowledge about concrete pump hydraulic system

Picture
Hanghzou truemax machienry & equipment co., ltd operating the concrete pump, a small concrete pump, concrete pump, concrete pumps for mining, fine aggregate concrete pumps, mortar pumps and other equipment for the maintenance of concrete has been very concerned about the topic of customers, here on this piece of concrete pump hydraulic system for users to answer.
Related maintenance and technical description of concrete pump hydraulic system:
First concrete pump hydraulic system before starting the work in the bottom of the precipitation water discharge tank. After every 50 hours of operation, open the drain valve at the bottom of the tank water. This time to pay special attention not to let the hydraulic oil flow. Also, the class detect minor hydraulic oil, the oil level should be at least 3/4 of the oil level gauge, otherwise filled; yellowish oil should be transparent, non-emulsified or turbidity, or should be replaced. The new hydraulic oil must be added to the manufacturer's recommended grade of hydraulic oil. The new machine after use 10,000 cubic meters ofconcrete machinery were the first oil change, after pumping 20,000 cubic meters per replacement.
Furthermore, every shift inspection cooler outside, if the dirt immediately wash, otherwise easily lead to oil overheating, leading to early hydraulic oil oxidation and damage the hydraulic system of the concrete pump. Check the vacuum table indicates per shift, should be in the green zone. Each shift Check the hydraulic system for leaks oil phenomenon, tank cover seal is loose, water intake. Per shift accumulator pressure checks whether the concrete pump manufacturer requirements, if not, please press.
In the start of the hydraulic system of conditions for concrete pump dry run. If the filter is in the red zone, said to replace the filter. If the filter indicator is in the green zone, the oil filter is working properly. Indicator has been in the yellow zone, indicating that part of the filter cartridge clogging; in the red area indicates that the oil filter cartridge is not properly filtered, the filter must be replaced. Under normal circumstances, the hydraulic oil filter cartridge must be replaced every 500h, and hydraulic return filter cartridge must be replaced every 1000h, and the first 200 hours of work necessary to replace the filter.
