Wholesale Roots pump in china, bearing cavity and gear cavity are arranged on both sides of the roots cavity, the motor cavity is connected with the bearing cavity, and shafts are set between the bearing cavity and the roots cavity and between the roots cavity and the gear cavity sealing device; the shaft sealing device is arranged on the driving rotor shaft and the driven rotor shaft; the motor is a rotor shaft shielded variable frequency motor; the bearing cavity and the gear cavity are provided with lubricating devices; the bearing cavity at both ends is provided with Oil and gas separation device; the invention has small volume, large pumping speed, energy and space saving; frequency conversion speed regulation, long service life; the use of Teflon double-lip shaft seals prolongs the maintenance period of the pump; the use of oil and gas separation device solves the problem of The leakage of oil vapor to the vacuum chamber; the motor rotor and the pump shaft are integrated, and the motor stator is in the oil chamber, which solves the problems of motor dynamic sealing and motor vibration; the assembly of the gear adopts the thermal expansion assembly structure, which reduces the friction of the moving part. Balance and Vibration.

In summary, this is a brief introduction to the basics of Wholesale Roots pump in china.
