The axial force of the screw vacuum pump may be caused by the uneven pressure on the suction and discharge ports, resulting in uneven pressure on both sides of the impeller, which is not completely symmetrical and produces axial force. But how to solve the axial force?
Although we need to clean up the axial force of the screw vacuum pump, if we clean it thoroughly, the rotor will rotate unsteadily. Therefore, it is necessary to compensate the amount of 30 by bearing in the design, so that the bearing at the non driving end of reciprocating vacuum pump is usually angular contact bearing, because this method can be used to withstand higher axial force.
The general solution is to symmetrically install the balance disk and impeller of the screw vacuum pump, and the single-stage pump generally has a balance hole on the impeller. Secondly, there is a way to install balance blades on the impeller to balance the axial force.
Screw vacuum pump will be affected by many factors in the process of operation. Any small problems may affect the normal operation. Therefore, regular inspection and maintenance are needed to avoid problems and reduce efficiency.
