Title: Displacement type vacuum pump
Inventor: YANAGISAWA KIYOSHI
IPC: F04C18/16
Filed: 1997-05-29
Granted: 1999-11-21
Abstract: A displacement type dry vacuum pump having dual shafts is disclosed. According to the present invention, the process gas is exhausted from a processing chamber through three compartments, a gas admittance pump section, a central drive motor section, and a gas discharge pump section to resolve the performance problems encountered in conventional dual shaft displacement type vacuum pumps. By placing the drive motor section in the center, thus separating the gas exhaust at low pressure from the processing chamber to an atmospheric pressure, to carry out the exhausting process in two stages, a number of advantages are obtained. Each rotor can be made to suit the pressure requirements so that the low pressure side rotors are made to displace a higher volume of gas than the rotors in the higher pressure exhaust section. By placing the drive motor in the center of the pump, it becomes possible to design a pump having the dual shafts supported only at one end, thus enabling to mount the rotors at the free ends of the pump which are closed with end plates which can be removed easily for servicing the pump sections. Also, the bearings are less exposed to harsh environments, and the exhaust gas can be flowed through a pipe provided in the stator section of the drive motor, so as to enable control of the temperature of the exhaust gas. Synchronous operation of the dual shaft pump by the magnetic coupling enables to lower power consumption and to extend the range of the operable pressures.
