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

1. Use servo motor to directly drive the main oil pump of hydraulic press to achieve energy saving. At present, there are still many difficulties in directly driving hydraulic pump with high-power servo motor, mainly requiring the speed range of hydraulic pump to be very large. The minimum speed of general hydraulic pump is 600
