Analysis of common failures of hydraulic synchronous motors
The main factor that affects the synchronization error of the synchronous motor The synchronous motor is composed of several motors with high machining accuracy and the same size. The same size and higher machining accuracy make the flow (displacement) through each motor approximately the same. F...
Classification of hydraulic valves
A component used to control the pressure, flow and direction of the liquid in a hydraulic transmission. Among them, the pressure control valve is called the pressure control valve, the flow control valve is called the flow control valve, and the flow control valve is called the directional contro...
The difference between open hydraulic system and closed hydraulic system
Open system (1) Open hydraulic system means that the hydraulic oil pump sucks oil from the oil tank, and supplies oil to the hydraulic cylinder (or hydraulic motor) through the reversing valve to drive the working mechanism. The oil return of the hydraulic cylinder (or hydraulic motor) is then r...
Overview and characteristics of flow control valves
Overview The flow control valve is a valve that relies on changing the fluid resistance of the orifice to control the flow of the orifice under a certain pressure difference, thereby adjusting the movement speed of the actuator (hydraulic cylinder or hydraulic motor). It mainly includes throttle ...
