Rotary dry vacuum pump |
| abstract |
A rotary dry vacuum pump is utilized to solve a problem that reacted gases produced by using a shielded motor as a drive portion may enter into the shielded motor, and lead to a failure of the rotary dry vacuum pump. A rotary dry vacuum pump has one or more impellers in a housing, bearings of rotating shafts of the rotors for supporting the impellers, a suction opening and a discharging opening for fluid being formed on the housing, and a circumrotating impeller consisting of at least a motor the one or more rotatively driven impellers. The aforesaid motor has a stator iron core fixed in the housing of the motor, which is installed on a partition wall of the inner diameter side of the stator and is fixed to the housing to seal the inside of the partition wall. A rotor is fixed to a rotating shaft in the partition wall so as to form a rotatable structure, and a gas inlet for pouring clean gas into the partition wall is provided. |
