What should I do if the oil temperature of the concrete pump rises too fast
The concrete pump is in use, if the oil temperature rises quickly, it can be inferred that it is caused by a leak in the hydraulic system. It is recommended to check the pressure at the outlet of the hydraulic pump first. If it is normal, there is no problem; then check the pressure at the accumulator inlet. If the pressure is very low, it means the air bag of the accumulator is broken. Replace the accumulator and test the machine.
If the fault phenomenon still exists after the overhaul, it is possible that the internal leakage of the one-way valve between the pump and the accumulator has caused the oil temperature to rise and the direction change is weak. Under normal circumstances, within a period of time just after the shutdown, it is possible to hear the sound of pressure oil unloading. At this time, the one-way valve can be disassembled. If it is found that the sealing surface of the valve has been severely worn and the hydraulic oil is turbid , Slightly emulsified. At this time, you can replace the one-way valve and hydraulic oil, and then test the machine, you will find that the drag pump returns to normal.
