What are the gearing situations of hydraulic pile drivers?

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

1, 1st gear, reverse gear 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 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 rule out the removal of the bearing cover, the O-ring and gasket must be removed and replaced. At this time, if there is no pressure oil overflow, then determine the 2 in the transmission The prefabricated components of the first gear are not very good. Be sure to engage the second gear. At the same time, check whether the outer skeleton seal of the second gear is damaged, then disassemble the prefabricated components of the second gear, remove the piston rod, check the engine piston, the skeleton seal ring and friction, and check the hydraulic pressure of the second gear Whether the guide pin in the cylinder falls off. If the guide pin falls off, the second gear pressure oil will be discharged here, causing the second gear pressure to drop, which is also difficult to do. Therefore, disassemble and replace the hydraulic seal or repair and replace 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 pressure indicated on the variable speed air gauge of the hydraulic pile driver. If the 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 gearbox oil Check whether the 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 pressure gauge indicates normal, the fault will be the auxiliary transmission gear of the transmission And the hydraulic input is damaged, so the driving force of the auxiliary transmission gear of the hydraulic torque converter cannot be output, only the driving force of the main transmission gear is output.
