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…

The differences between hydraulic motors and pumps are as follows:(1) Hydraulic pump is a device that converts mechanical energy of motor into hydraulic energy, and outputs flow and pressure, hoping for high volume efficiency;Hydraulic motor is a device t

Daily use of reducer should pay attention to:1. Maintaining the height of the medium;2. Cleaning and irrigation are needed after each operation to ensure that there is no accumulated material in the irrigation.3. The rotation direction of irrigation shoul

Because of the high water content of ore, when excavator works in the cabin of ore transport ship, the ore slurry is often squeezed into the gap along the guard plate of the walking motor protection box and the through hole of the rubber pipe installation

Although excavators mainly carry out excavation operations, but the operation of walking is also very important! The following aspects should be paid attention to in the operation of excavator walking:1. Before the excavator starts, it should check the en

Many friends mentioned that they had encountered the situation of the excavator running off in the course of operation. What is the reason? And how to solve it?1. The movement of the main valve spool of the walking excavator deflection is out of orderWhe…

If the excavator is compared to a person, then the walking parts of the excavator are equivalent to human legs. Therefore, the walking parts of excavator are very important original parts, which need careful maintenance to ensure its good work. Many excav

The walking part of excavator is composed of supporting sprocket, supporting wheel, driving wheel and rail chain. When it runs for a certain time, these parts will be worn to a certain extent. However, if the idea of daily maintenance, as long as a little
