The directional control valve is mainly used to open and close the oil circuit or switch the direction of the oil flow to meet the requirements for the start, stop and movement direction of the actuat...
There are many types of hydraulic control valves, which can be divided into the highest pressure of the system and the actual flow through the valve according to different characteristics, and conside...
Both hydraulic pumps and hydraulic motors are energy conversion elements in hydraulic transmission systems. What exactly is the difference between the two? How to differentiate? Where are they applied...
We should determine the type of hydraulic pump according to the type and working conditions of the main engine, the power size and the performance requirements of the system, and also consider the qua...
Nowadays, the development of the machinery industry is more and more advanced, and the hydraulic industry is also born. The hydraulic pump is the power component of the hydraulic system, its function ...
1. The basic principle of plunger pump accessories: the volume of the cylinder is repeatedly changed by the hydraulic action of the plunger in the cylinder to inhale and discharge the fluid.2. Working...
The basic concept of the hydraulic system:1. Hydraulic oil pressure:The air we live in is at atmospheric pressure, and its value is about 1 bar. (1 bar = 0.1 MPa) atmospheric pressure retains the air ...
The characteristics of the failure of the hydraulic system of construction machinery. The hydraulic mechanical transmission system is mainly composed of hydraulic pumps, control valves, torque convert...
A plunger pump supplied by a charge pump is used. After 3000 hours of use, the operator needs to check the plunger pump 1-2 times a day to check whether the operating sound of the hydraulic pump is no...
Traditionally, vane pumps, especially variable vane pumps, are mostly used in fixed installations of industrial and mining equipment and ships. However, in recent years, many walking machines have als...
