High pressure vane pump is introduced in detail

High pressure vane pump | overview
High pressure and low energy consumption is one of the major features of modern industrial products -- wide application of hydraulic transmission and control technology;
High speed, high pressure, low noise hydraulic pump is a new generation of machine tools, ships, metallurgy, light industry and engineering machinery hydraulic system necessary products;
The hydraulic pump is a device which converts the rotating mechanical energy of motor or engine into positive displacement fluid energy and realizes the automation or semi-automation of hydraulic machinery through the control element.
Vane pump is superior to gear pump (external meshing type) and plunger pump because of low noise, long life, small pressure pulsation, good self-absorption performance.
A vane pump is a hydraulic machine that converts the mechanical energy of a power machine into hydraulic energy (potential energy, kinetic energy, pressure energy) by rotating the impeller. Half a century ago, circular vane pump (pressure 70 bar, displacement 7-200 ml/rev, speed 600-1800 RPM) was first applied to hydraulic transmission of machine tools. At the end of last century, the column-pin vane pump (pressure 240-320 bar, displacement 5.8-268 ml/rev, speed 600-3600rpm) led by the American company entered the global hydraulic product market and won the attention of the hydraulic industry. In the case that the mechanical strength of the part of the pump is sufficient and the seal of the pump is reliable, the high-pressure performance of the blade pump depends on the life of the friction pair between the blade and the stator.

| structure and features of high pressure vane pump

General characteristics
All kinds of high pressure vane pumps have something in common in structural design
For example: combination pump core and pressure compensation oil plate, materials, heat treatment and surface treatment technology, fine tooth involute spline, bolt locking torque, etc.
The combination of pump core
The service life of the double-acting vane pump is longer than that of the gear pump. In the case of a clean hydraulic system, it can generally reach 5000-10000 hours.
In order to make it convenient for users to maintain oil pumps on site, the vulnerable parts, such as stator, rotor, blade and oil distribution plate, are usually combined into an independent pump core, and the damaged oil pump is replaced quickly.
Combined pump cores with different displacement can also be sold as independent commodities in the market.
