Hydraulic transmission is a common way of power transmission, widely used in engineering machinery, aerospace, metallurgy, ships and other fields. The Hydraulic Pump, as one of the core components of the hydraulic transmission system, is responsible for generating high pressure liquid and providing the power source. In hydraulic transmission, the commonly used hydraulic pumps can be divided into several different types, including gear pumps, vane pumps, piston pumps and screw pumps. Understanding these different types of hydraulic pumps and their characteristics is essential for the proper selection and use of hydraulic transmission systems. What types of hydraulic pumps are commonly used in hydraulic transmission
First of all, the gear pump is one of the most common pumps in hydraulic transmission. It consists of a pair of gears that mesh with each other to produce fluid flow by turning the gears. Gear pumps are simple in structure, small in size and light in weight, and have high efficiency and pressure stability. However, gear pumps have poor sealing performance, are noisy and are suitable for low to medium pressure applications. Secondly, the vane pump is another common type of hydraulic pump. It consists of a rotating rotor and fixed vanes. As the rotor rotates, the vanes create a radial motion along the inner wall, which creates the pump chamber and the suction, compression and discharge of the fluid. The vane pump has high pressure stability and good self-priming capability and is suitable for medium to high pressure applications. The plunger pump is a High Pressure Hydraulic Pump that delivers liquid through the reciprocating motion of the plunger in the pump chamber. There are two types of piston pumps, radial piston pumps and axial piston pumps. The plunger of the radial piston pump moves in the direction perpendicular to the pump shaft, while the plunger of the axial piston pump moves in the direction parallel to the pump shaft. Plunger pumps have high pressure, high efficiency and compactness for high pressure hydraulic systems and applications requiring high power output. Finally, the progressive cavity pump is a special type of hydraulic pump suitable for transporting high viscosity fluids. It consists of a rotating screw and a fixed housing. As the screw rotates, the liquid is pushed along the screw's helix to the outlet. The screw pump has a high self-priming and conveying capacity and is suitable for applications involving high viscosity fluids in hydraulic systems. In summary, the hydraulic pumps commonly used in hydraulic transmission include gear pumps, vane pumps, piston pumps and screw pumps. Each pump type has different characteristics and scope of application. The correct choice of the appropriate type of hydraulic pump is critical to the performance and reliability of the hydraulic transmission system. In the selection, the needs of the system, operating conditions and special requirements need to be taken into account to ensure that the most appropriate type of hydraulic pump is selected.
