The use of hydraulic pump drive shaft and attention points

Hydraulic pump drive shaft in the use of the process need to pay attention to a lot of things, but first of all, we need to understand the working principle of the hydraulic transmission shaft.

The transmission shaft of hydraulic pump can not bear radial force and axial force, so it is not allowed to install belt pulley, gear and sprocket directly at the end of shaft, which is usually connected with shaft and pump shaft by coupling.

For example, due to manufacturing reasons, the coaxial degree of pump and shaft is over standard, and there is deviation when assembling. With the increase of pump speed, the centrifugal force increases the deformation of coupling, the deformation is large, and the centrifugal force increases. A vicious circle, the result of vibration and noise, thereby affecting the service life of the pump. In addition, there are factors such as coupling pin loose, not timely fastening, rubber ring wear is not timely replacement and other factors.
