With the construction of the fiery edifice, concrete pump for its convenience and high efficiency in a rapidly occupied major construction site, but the good equipment is not well maintained, inevitably there will be trouble in one way or another. Now talk about the common fault of concrete pump and the solution.

How to Solve Common Concrete pump Problems in Construction

1, engine speed down

First, to test the engine output power, if the engine output power is lower than the rated power, it is the poor quality fuel, the fuel pressure is low, there is something wrong with the brake and its control rod and the turbocharger of coke. If the engine output power is normal, it is necessary to see whether the flow rate of the pump and the engine output power does not match. This kind of breakdown must start from the electrical system, then examines the hydraulic system, finally examines the mechanical transmission system.

2, solenoid valve does not work

Control valve in the operation panel, manual and automatic can open solenoid valve, solenoid valve replacement or pilot valve or manual operation button; open solenoid valve on the outlet of the exhaust, replace the solenoid valve; manually open solenoid valve outlet exhaust, check cylinder, internal ring, piston the pressing screw rod, and other air leaks.

3, working speed is slow

Slow down the speed of the pump is mainly due to the wear of the engine caused by the wear of the engine and the hydraulic system. Hydraulic pump for piston pump, after working for a certain time, the internal hydraulic components (pump cylinder, piston, abalone plate) inevitably produce excessive wear will cause leakage, the parameter data is not coordinated, resulting in inadequate flow of oil temperature is too high, the slow pace of work. At this time the need for the overhaul, the wear out of the spare parts repair replacement. Drag pump AUID (automatic idle) technology, effective control of fuel consumption and engine wear, as well as variable pump control system, higher accuracy, efficiency is also enhanced!

4, belt machine, cylinder does not work

The belt is running to regularly check the roller operation, found to timely replacement does not turn, cannot work, otherwise it will lead to the belt scratch, electric roller lubricating oil belt machine to regular inspection, timely add, replace. Check and remove cylinder internal sludge.
