Damping method of dry vacuum pump

Equipment in the fitness exercise, the shell is caused by vibration, mild vibration is not easy to cause harm to the equipment, but vibration frequency too much will damage the equipment, today’s key to analyze the dry vacuum pump shock absorption method content, firmly believe that in other machinery and equipment should also have a certain application.

1. Improve the bending stiffness of pipe
Considering the difficulty of lifting dry vacuum pump, the method of welding “rib” on the seamless steel pipe at the inlet and outlet is adopted. Along with the direction of water in and out, 8 thick steel plates with thickness of 32mm and total width of 100 mm are used to weld the expansion pipe and the convex boss on both sides of the seamless steel pipe between the inlet and outlet valves of the mechanical pump. Improve the bending stiffness of seamless steel pipe, reduce deformation and resist offset. According to the measurement, the offset of point a of dry vacuum pump is reduced to 0.35 after rib.

2. Renovate the transmission device
In order to reduce the vibration of the motor and the rotating shaft to the root mechanical pump, the rigid connection between the rotating shaft and the rotating shaft is changed into a ductile connection. When gb4323-84 malleable sleeve pin coupling is used, the large compensation offset is 0.6 mm, and the compensation included angle is 1 ° 30. In this way, the vibration of motor and rotating shaft can be compensated according to the elastic coupling, and it is not easy to transmit to the mechanical pump immediately.

The above content tells you that the damping method of dry vacuum pump is mainly based on improving the bending stiffness of the pipeline and improving the transmission device. In addition, it is reasonable to select vibration reduction measures according to the natural environment of raw materials.
