The mixer pump is a commonly used concrete pumping equipment in construction projects, one of the essential tools in modern construction projects. But even the best products have wear and tear or failure, if the problem is not big and do not need to after-sales run a trip, we can overhaul themselves.

Listed below are a few common problems for reference:

1. The solenoid valve does not work; in the control panel operation of the solenoid valve, whether manual or automatic can not be opened, you can replace the battery valve coil, if you can not open the battery valve manually, please check the cylinder interior, seals, piston bolts, screws, and so on whether the air leakage.

2.Work efficiency slows down; the use of the process of mixer pump wear and tear caused by the slowing of work efficiency, may be the whole machine internal wear caused by the hydraulic system internal leakage. Trailer pump hydraulic pump for the plunger variable pump, work for a certain period of time, the pump internal hydraulic components (cylinder, plunger, nine-hole plate, etc.) inevitably produce too slow. At this time it is necessary to overhaul the whole machine, repair and replace the parts that are worn beyond the limit. Tow pump technology, effective control of fuel consumption and engine wear, and variable pump control system, higher precision and efficiency!

3.Belt machine, cylinder does not work when the belt is running to frequently check the operation of the drag wheel, found that there is not turn to be replaced in a timely manner, can not work with a disease, otherwise it will lead to the belt scratched, belt machine electric rolling lubricant should be regularly inspected, added in a timely manner, replaced. Demolition and inspection to remove the oil sludge inside the cylinder.

4. the daily maintenance of the pump in order to prevent failures, in the daily use of the process need to pay close attention to the maintenance of the pump, and the maintenance of the pump in accordance with the operating instructions, such as improper maintenance, may lead to sealing damage, resulting in leakage of slurry or damage to other parts.

5. The speed of the pumping machine is reduced first of all to test the engine itself output power, the brake and its joystick have a problem and turbocharger carbon. If the engine output power is normal, you need to check whether the flow of the hydraulic pump and the engine output power mismatch. This type of failure to start with the electrical system, and then check the hydraulic system after checking the mechanical transmission system.
