Little knowledge about hydraulic pump

Because the hydraulic system plays a more important role in CNC machine tools. Especially in CNC lathe more applications. So find out the relevant knowledge for your reference. The hydraulic circuit of hydraulic basic circuit is a hydraulic system drawn with graphic symbols. Hydraulic system is used to realize the action required by the machine, and its composition is various, according to the requirements of the machine. When the machine moves complex, the hydraulic system is also complex, but the complex hydraulic system is also composed by some basic circuits.

Components of hydraulic system

The hydraulic system is now in a variety of mechanical equipment widely used, with a continuous flow of fluid (i.e. hydraulic oil), through the hydraulic pump to drive the hydraulic pump motor or engine mechanical energy into fluid pressure energy, through a variety of control valve (pressure control valve, flow control valve, direction control valve), as to the actuator hydraulic cylinder or hydraulic motor, and then converted into mechanical power to drive load. This makes up a hydraulic system.

Classification of hydraulic systems

According to the basic constitution of hydraulic circuit, the hydraulic system can be divided into open system and closed system. The pump of the open system is pumped from the tank, and the system returns oil to the tank. Its application is universal. The closed system is an oil inlet which is discharged from the oil motor and returns to the oil inlet of the pump, which is used for the driving and driving of the vehicle. According to the main function of hydraulic system, it can be divided into drive system and control system.
