Through planned maintenance, the oil leakage of the excavator push-down gearbox was reformed. So far, no leaks were found, the frequency of faults was reduced, satisfactory results were obtained, and significant benefits were achieved, saving man-hours and effectively reducing the number of times. The labor intensity of the operator.
Through technical transformation, it solves the difficult problems that have not been solved for many years, reduces the cost, improves the effective utilization rate of equipment, and has certain reference significance for the modification of excavators with similar problems. Due to the material of the yin and yang rotor, the material of the inlet and exhaust seats is large, so the damage to the intake and exhaust seats is large. The machine is a coupling piece, which cannot be changed by one. The replacement of the whole set costs about 10,000 yuan. If the repair welding is easy to produce white mouth, it is not easy to process, and it may cause thermal deformation of the exhaust seat.é‚Inlaid sleeve method, the original perforated hole car of the exhaust damaged part is the towel, the thickness is the price of the hole car at the air intake seat end, because the air pressure machine has a large temperature difference during the working process, the cover and the base material Try to use the same material as much as possible, otherwise it may deform or fall off. Therefore, use the two plates of the material car, gently tap into the hole with a hammer, then divide the hole and the buckle in three equal parts, and fix the disk to the hole with the screw. Then install the intake and exhaust seats onto the cylinder block. Then, the upper trampoline persuaded the two price holes according to the original size, and removed the plane higher than the plane based on the plane of the inlet and exhaust seats, so that the machined part was basically completed. Installation and commissioning First, the inlet and exhaust seats are sleeved and the damage is unevenly polished with oilstone. The cylinder and the yin and yang rotor are also ground and assembled.
