description

Constitute:
Power take-off is one or more sets of variable speed gears, also known as power output, which is generally composed of a gear box, clutch, and controller. It is connected with the low gear of the gearbox or the output shaft of the auxiliary box to output power to the outside. Working devices, such as lifting pumps, etc.

Maintenance：
When the power take-off of a heavy-duty dump truck fails, the most direct and obvious result is that the gear pump does not rotate, the hydraulic dumping system loses its power source, and the entire system is in a state of paralysis and cannot work.

Pneumatic power take-offs are mostly used on heavy dump trucks, which are mainly composed of three parts: transmission mechanism, connecting mechanism and operating mechanism. The most common fault in these three parts is the operating mechanism, which uses solenoid valve to switch the air circuit. The solenoid valve controls the control cylinder of the power take-off, so as to complete the shifting and shifting work of the power take-off. During the unloading process, the solenoid valve must be operated frequently, and its parts are easily damaged and invalid. Therefore, the effectiveness, sensitivity, circuit safety and switch of the solenoid valve should be checked frequently. If the circuit is normal, the working condition of the power take-off cylinder should also be checked. , Whether there is no air leakage or air leakage, if necessary, disassemble the power take-off cylinder to check.

The transmission mechanism and the connecting mechanism should also be maintained and maintained frequently. When the gears of the transmission mechanism are poorly meshed, and the connecting bolts of the shift fork and the push rod are loose, abnormal noises will occur. Check the fastening bolts of each part. At the same time, check the lubricating oil condition and clean up the dirt in time to keep the parts clean and intact to prevent bumps. , Scratch. In addition, the connecting bushing between the power take-off and the oil pump should be checked frequently. If it is not firm, damaged, taken off or broken, it should be replaced in time.
