Abstract
The invention relates to a direct connecting flame proof oilless vortex vacuum compressor. The technical problem to be solved by the invention is to provide a motor and a compressor which have higher concentricity, small shake and lower low noise, further increase the compressive efficiency and reduce the mechanical loss. The reasonable and effective thermal design causes that the compressor and the motor both have good heat dissipation and ensure a machine to work normally. The semi-closed or the total closed structural design realizes the no leakage of the flame proof oilless vortex vacuum compressor. The technical proposal to solve the problem is that a main shaft is connected with a driving disk by a needle bearing and provided with a shaft gland before extending a motor shell; a flame proof plate is arranged between a machine frame and the motor shell and a non-magnetic metal thin wall separation sleeve is fixed in a sealing way between the flame proof plate and the bottom of the motor shell; a stator, the machine frame, the flame proof plate and the motor shell form a heat dissipation system which are mutually communicated. The vacuum compress is applied to the application field of low compression ratio flammable and explosive gas compression and evacuation.
