How does orbital hydraulic motor work?

Orbital Hydraulic Motor: The inner gear ring is fixedly connected with the housing, and the oil entering from the oil port pushes the rotor to rotate around a central point. This kind of slowly rotating rotor drives the output through spline shaft and becomes orbital hydraulic motor. After t... Read More

3 Types of Control Valves Used in Hydraulic Systems

Hydraulic power systems are very common in the field of automotive, car, and aerospace equipment. They possess a strong power-to-weight ratio as well as being able to get idle, intermittently worked and even reversed. They can also move rapidly, and react quickly. Another appealing advantage of t... Read More

Common Causes of Hydraulic Seal Failure

Hydraulic seals are ringed components that form seals in motion applications involving liquid. These important components are critical components in the success of reciprocating motion aided transfer of liquid power to linear motion. Relatively soft, hydraulic seals can be composed of a number of... Read More

What is a Hydraulic flow control valve?

A Hydraulic flow control valve adjusts and controls the volume flow of air within a pneumatic system. They can often be used to adjust the speed of operation of an actuator. They should not be confused with pressure controllers, or regulators. Whilst there is a relationship between pressure and f... Read More
