New Main pump

The main pump is the heart of the hydraulic system, mainly providing the pressure of the hydraulic oil, transporting the hydraulic oil through the hydraulic system pipeline, driving the hydraulic actuator to complete the work, it is a key component in many mechanical equipment. The main pump is generally composed of pump body, pump cover, pump gear, oil port and other components. According to the different structures, it can be divided into gear pumps, piston pumps, vane pumps, etc.

First, Definition and Function

A main pump usually refers to a pump in a mechanical device that is used to provide the primary power or fluid. It is responsible for transporting liquids or gases from low-pressure areas to high-pressure areas to meet the operational needs of the equipment.

Second, Common types

There are many different types of main pumps to suit a variety of applications:

1. Centrifugal pump: Centrifugal force is used to throw the liquid from the center to the surroundings, so as to produce a pressure difference and make the liquid flow.

2. Piston pump: Conveys liquid through the reciprocating motion of the plunger in the cylinder, which is often used in high-pressure and large-flow occasions.

3. Gear pump: It consists of two or more gears meshing with each other to convey the liquid through the rotation of the gears.

4. Screw pump: The rotation of the screw is used to transport liquid, which is suitable for high-viscosity and particle-containing media.

Third, the field of application

Main pumps have a wide range of applications in various fields, such as:

1. Petroleum industry: used for fluid transportation in the process of crude oil extraction, transportation and refining.

2. Chemical industry: used for the transportation of various chemical media and pressure control in the reaction process.

3. Electric power industry: used for cooling systems and fluid transportation in power generation facilities such as nuclear power plants and hydropower stations.

4. Machinery industry: used in the hydraulic system of machine tools, injection molding machines, die-casting machines and other equipment.

Fourth, purchase and maintenance

When selecting a main pump, factors such as the specific needs of the equipment, the nature of the medium, the working pressure and the flow rate need to be considered. At the same time, it is also necessary to choose a brand with a good reputation and after-sales service.

When using and maintaining the main pump, pay attention to the following:

1. Regular inspection: check the wear of the pump body, the sealing performance and the lubrication of the bearing.

2. Timely replacement: If it is found that the parts with serious wear and tear should be replaced in time, so as not to affect the performance and life of the pump.

3. Keep it clean: Regularly clean up the debris in the pump body and around it to keep the working environment clean.
