Embodiment 2

[0024] Example 2, such as Figure 4 As shown, this example is a non-leakage, explosion-proof and oil-free scroll vacuum compressor. The difference between this example and Example 1 is that the main shaft 35 is sealed in the motor casing 31, and the motor casing 31 and the guide A heat dissipation fan 49 with a power source 51 is arranged between the wind shields 43, so that there is no dynamic sealing interface between the inner chamber of the whole machine and the outside to ensure no leakage. This model can be used in special fields such as the compression and transportation of toxic and harmful gases.

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.

Description

technical field [0001] The invention relates to a vacuum compressor, in particular to a direct-connected explosion-proof oil-free scroll vacuum compressor. It is suitable for the application field of flammable and explosive gas compression and vacuum pumping with low compression ratio. Background technique [0002] At present, in the non-refrigeration industry of scroll compressors, there are no mature technologies and products that are leak-proof and explosion-proof. No leaks. As a result, the advantages of low noise, high reliability, and low energy consumption of the oil-free scroll compressor cannot play a good role in the leakage-proof and explosion-proof compression application fields. This is not only a pity for the compressor industry, but also a disappointment for the majority of compressor users. However, whether it is energy consumption, noise, reliability, volume and other indicators of the compressor, especially the quality of the oil-free scroll compressor r...
