Composition and function of hydraulic pump
Jan 15,2024
Hydraulic pump is a device that converts mechanical energy into hydraulic energy and is widely used in various industrial fields. This article will be described from the composition and function of the hydraulic pump.
Composition of 1. hydraulic pump
The hydraulic pump is mainly composed of the following parts:
1. Pump body: The pump body is the main shell of the hydraulic pump, which is used to install and support other components. The interior of the pump body contains one or more pump chambers for sucking in liquid and discharging it.
2. Bearing: The bearing is used to support the pump body and rotor, reduce friction and vibration, and ensure the normal operation of the pump.
3. Shaft seal: Shaft seal is used to prevent liquid leakage, usually using a sealing ring or mechanical seal device. 4. Rotor: The rotor is the core component of the hydraulic pump, which generates centrifugal force through rotation to suck and discharge the liquid into the pump cavity.
5. Suction pipe: The suction pipe is used to transport the liquid from the liquid source to the suction port of the pump. 6. Discharge pipe: The discharge pipe is used to discharge the liquid in the pump chamber to the hydraulic system.
Function of 2. hydraulic pump
The main function of the hydraulic pump is to generate pressure and transport liquid from the low-pressure area to the high-pressure area to provide the required power for the hydraulic system. Specific functions are as follows ︰
1. Suction liquid: the hydraulic pump generates centrifugal force by rotating the rotor, and sucks the liquid into the pump chamber from the suction port.
2. Compressed liquid: When the rotor inside the hydraulic pump rotates, the liquid is compressed and pushed to the discharge port. The pressure of the liquid in the pump chamber increases, forming fluid pressure energy.
3. Provide power: The high-pressure liquid generated by the hydraulic pump can provide power to the actuators in the hydraulic system, such as hydraulic cylinders and hydraulic motors. Through the pressure transmission of the liquid, the movement and control of the construction machinery are realized.
4. Maintain system pressure: The hydraulic pump can maintain the working pressure of the hydraulic system to ensure the stability and normal operation of the system.
Summary:
Hydraulic pump is a device that converts mechanical energy into hydraulic energy. It is composed of pump body, bearing, shaft seal, rotor, suction pipe and discharge pipe. The main function of the hydraulic pump is to generate pressure and transport liquid from the low-pressure area to the high-pressure area to provide the required power for the hydraulic system. Hydraulic pumps play an important role in the industrial field and are widely used in various hydraulic equipment and mechanical systems. Through the work of the hydraulic pump, the hydraulic system can achieve accurate control and efficient power transmission, and improve work efficiency and production efficiency.
