Hill pushed the bulldozers accessories the functions and features of common, today let's hill pushed the bulldozer gear pump failure problems for analysis Hill pushed the bulldozer can be divided into different types, can be divided for crawler type dozer and two tyred bulldozer. The crawler dozer adhesion traction is big, grounding than the small, so strong climbing ability, more used to what place or potholes more ground. And the high speed wheel bulldozer, flexible, short cycle time of operation, convenient transport, so is suitable for the need to frequently change site and field work. Hill pushed standard bulldozer turbo engine, powerful, high efficiency and energy saving, large torque reserve coefficient. Planetary power shift gearbox compact structure, smooth shift, high efficiency, long service life. The machine forward backward, and steering gear transformation is controlled by single lever PPC, convenient and flexible. Extended crawler grounding length to ensure machine low pressure, high stability and strong traction. Hill pushed the bulldozers accessories When the large gear pump seal damage or failure, will cause the generation between cover and shell oil before and after; Small seal failure or damage, can cause internal leakage; Driving gear shaft self-tightening seal aging or damage, will cause the active gear axle oil or gas leakage; Collar end surface scratch or wear serious, cause the axial channeling, and damage the small seal in clearance, produce the oil; The oil outlet flange sealing ring size is too small or packing, may cause oil leakage. Hill pushed the bulldozer once it can be seen in the process of using to observation of failure in this leak phenomenon, in particular, the bulldozer parts has worn very seriously, remember timely maintenance and maintenance
