Title: Operation of inverter-driven oil-free screw vacuum pump
Inventor: NAYA KOTARO
IPC: H01L21/205
Filed: 1987-02-26
Abstract: PURPOSE:To simplify the whole device by adjusting the pressure in a reaction tank by the revolution speed of a screw type vacuum pump through an inverter. CONSTITUTION:A vacuum pump 21 is a screw type which is controlled in variable ways by an inverter, and the pressure in a reaction tank 1 is decompressed at the revolution speed less than a prescribed revolution speed until a certain pressure is realized. Then, decompression is performed by the revolution speed larger than a prescribed revolution speed, and when process gas is introduced, the pressure in the reaction tank 1 is kept constant by increasing or decreasing the revolution speed according to the variation of the flow rate of the process gas. Therefore, the need of a slow exhaust valve, main valve, pressure adjusting valve, etc., can be avoided.
