1. “Obedient” control performance: function ≠ performance! What is the core task of hydraulic valves? It is not “being able to adjust pressure”, but “adjusting steadily and accurately”! For example: the same pressure regulating valve, some valves have very good data in the laboratory, but when installed on the equipment, the pressure fluctuation is as […]

The hydraulic support is the core equipment of the fully mechanized mining face. During the coal mining process, it can effectively support the weight of the roof rock to prevent the roof from collapsing and endangering the safety of personnel and damaging the equipment. It can also move flexibly as the coal mining progresses to

If insufficient pressure occurs during the operation of the hydraulic press, it may be caused by low efficiency or excessive leakage, damage or blockage of the relief valve, too little hydraulic oil, blockage of the oil inlet pipe or oil filter, severe wear or damage of the hydraulic pump, etc. During maintenance, the oil level,

Correct installation of hydraulic hoses is extremely important. Most hose failures are caused by improper installation of the hose assembly on the hydraulic system. 1. Hydraulic pipeline layout basics In the hydraulic system, the fixed layout is connected by steel pipes, and the layout between the movable parts is connected by hoses. If the cost

Hydraulic proportional valves and servo valves are more common in hydraulic systems. There is always an ambiguous feeling between the two. So, what are the similarities and differences between them? 1. Similarities (1) Basic functions ① Hydraulic control: Hydraulic proportional valves and servo valves are both hydraulic control components. Their core function is to control

1.Selection and installation of hydraulic gear pumps When selecting a hydraulic gear pump, it is necessary to make a judgment based on the properties of the liquid to be transported. At the same time, it is necessary to conduct a detailed inspection of the pump’s performance requirements and analyze its suction and discharge conditions, whether

The motor model is a code used to facilitate business contacts between users, designers, manufacturers and other departments and to simplify the description of product names, specifications, models, etc. in technical documents. The motor model consists of four parts: motor type code, motor specification code, special environment code and supplementary code. 1. Motor model composition

1.What is a balancing valve? Compared with other hydraulic valves, the balancing valve is called a special hydraulic valve because of its different functions and places of use. In many applications, the direction of the load force is the same as the direction of movement. At this time, the speed can be controlled by a

Violent vibration of hydraulic pumps is often a warning of abnormalities in the hydraulic system. This vibration will not only reduce the overall performance of the hydraulic system but may also cause premature wear or even damage to hydraulic components. Accurately identifying and solving the causes of hydraulic pump vibration can effectively improve the operating

Hydraulic jack is a mechanical tool designed based on Pascal’s law (liquid pressure transmission principle). It uses the hydraulic system to amplify small forces into large forces to achieve the lifting, support or displacement of heavy objects. Its core features are strong load-bearing capacity, stable operation and precise control. It is widely used in automobile
