What are the gearing situations of hydraulic pile drivers?

Daily maintenance is really a big thing in everyone's mind. Some careful owners will scrub the pile driver every day to keep it in a stable condition, but do you know if his maintenance is appropriate? Today, the small editor of Havok Machinery A few high failure probabilities are presented to analyze these situations for everyone. What are the different situations?

1, 1st gear, reverse gear everything is normal, 2nd gear has no driving force--hydraulic pile driver

First check whether the variable speed rocker arm of the hydraulic pile driver is reasonable. If it is not installed in place, please adjust it again. Then check whether the variable speed air gauge is at the second gear to reduce the pressure. If there is working pressure oil discharged from the outer field of the 8-shaped bearing end cover of the reducer, if there is water leakage , Tighten the anchor bolts for 4 weeks. If the above method still cannot prove the removal of the type bearing cover, the O-ring and gasket must be removed and replaced. At this time, if there is no pressure oil overflow, make sure the The 2nd gear component is not very good. Be sure to hang 2nd gear. At the same time, check whether the 2nd gear outer frame seal is damaged, then disassemble the 2nd gear component, remove the piston rod, and check the engine piston, frame seal and friction Check whether the guide pin in the 2nd gear hydraulic cylinder falls off. If the guide pin falls off, the pressure oil of the 2nd gear will be discharged here, resulting in a decrease in the working pressure of the 2nd gear, which is also very difficult to do. Therefore, disassemble and replace it Hydraulic seals or repair and replace with new parts.

2, first gear, reverse gear fatigue, 2nd gear driving slow - hydraulic pile driver

First of all, check whether there is any problem with the working pressure indicated by the variable speed air gauge of the hydraulic pile driver. If the working pressure exceeds 108kpa, increase the accelerator pedal to check the pneumatic; if the vibration is strong, it means that the turbine oil in the gearbox is too dirty or the remaining oil is insufficient. Check the transmission Check whether the tank oil level check plug can drain the turbine oil. If the oil drain is dirty, clean the transmission and the filter element, and then replace with new oil; if the remaining oil is normal, and the transmission air pressure gauge indicates that everything is normal, the fault is undoubtedly the auxiliary transmission of the transmission The transmission gear and hydraulic input are damaged, so the driving force of the auxiliary transmission gear of the hydraulic torque converter cannot be derived, and only the driving force of the main transmission gear can be derived.
