Walking operation is one of the important operations of crawler excavator. Unlike automobiles, excavators do not mainly run on the road. It is very harmful to the crawler when they walk for a long time. What should excavators pay attention to in the proce

Hydraulic pump is the power component of the hydraulic system. Its function is to convert the mechanical energy of the prime mover into the pressure energy of the liquid. It refers to the oil pump in the hydraulic system, which provides power to the whole

The storage capacity of excavator accessories is mainly related to the following factors:The sealing device used to wet the oil through the function test of the factoryThe storage capacity of rubber materials is usually affected by the following factors:H

Analysis of gear oil deficiency in small excavator rotation may lead to failure reasons:1. Except for hydraulic motors and gearbox, other devices can not work properly.2. Overwear of friction pairs of hydraulic motors leads to pressure oil leakage.3. The

Hydraulic pump is the power component of hydraulic system, which is driven by engine or motor to inhale oil from the hydraulic tank and form the pressure oil to be discharged and sent to the implementing component. Hydraulic pumps are divided into gear pu

The reason of gear oil shortage in excavator rotation is analyzed.1. Except for hydraulic motors and gearbox, other devices can not work properly.2. Overwear of friction pairs of hydraulic motors leads to pressure oil leakage.3. The main part of the hydra

Why need gear oil?This is because there are many sets of planetary gears in the walking reducer. When the excavator is walking, the gears inside are rotating at high speed, so it is necessary to add gear oil for lubrication.Why only half the position?The…
