The utility model relates to the technical field of
vacuum pump, concretely is a water -cooling sealed motor roots
vacuum pump, including integrated shell, one end of integrated shell is connected with sealed baffle and installs on
double wall board another end, makes the contact surface between integrated shell and
double wall board form static seal surface, the isobaric sealed chamber is formed in integrated shell inside, integrated core shaft,
induction motor rotor and split type
induction motor stator set up in isobaric sealed chamber. The utility model discloses through changing the external motor to built -in water -cooling sealed motor, improves the use performance of
vacuum pump and prolongs the service life of vacuum pump, the structure is relatively simple, cancels the shaft
coupling of traditional structure, and transmission is more stable, and transmission efficiency is higher, the sealing performance of precision seal lifting pump is improved by changing the dynamic seal in traditional structure, and integrated internal
water cooling can provide better cooling environment compared with traditional air -cooled motor structure.
