In the product manual of vane pump, there are generally detailed installation guidelines and precautions. However, in the actual use process, there are often such failures and problems. Most of these problems should be caused by improper use. Improper use accounts for more than 95% of the oil pump damage, but few of them really belong to product quality problems. 1、 Improper use of several manifestations: 1. Wrong installation method: A. Coupling too tight: Because the clearance between coupling... Read More
Hydraulic pumps are divided into gear pumps, piston pumps, vane pumps and screw pumps. Each pump has its own characteristics and is applied in different mechanical or industrial equipment. I. Gear Pump Pressure range: 2.5~28MPa; displacement range: 0.3~650ml*r; flow fluctuation: large; higher speed: high; volumetric efficiency: 0.7%~0.9%; total efficiency: 0.6%~0.8%; self-priming performance: excellent; noise: large; price: lowest; pollution resistance: excellent; commonly used in construction m...

In addition to the general characteristics of positive displacement pump, vane pump also has the following characteristics. 1. Relatively uniform flow, stable operation and low noise. 2. Double acting vane pump adopts radial force balance, long bearing life, good internal sealing and high volumetric efficiency, which can be used in high pressure applications. Generally, the rated working pressure of vane pump is less than 7MPa, and that of high-pressure vane pump is 14-21mpa. 3. Compact structur... Read More
