Description

Scroll compressor and assembly process thereof

Technical Field

The invention relates to the technical field of scroll compressors, in particular to a scroll compressor and an assembly process of the scroll compressor.

Background

As the ambient temperature decreases, the evaporating temperature of a conventional air-source heat pump system also decreases. Under the condition that the condensation temperature is not changed, the compression ratio of the compressor is increased, the suction specific volume of the compressor is increased, the gas transmission coefficient is reduced, the compression process of the system is seriously deviated from the normal compression process, and the compression efficiency is rapidly reduced. When the ambient temperature is reduced to be lower than zero degree centigrade and the evaporation temperature is too low, the compression ratio of the compressor is increased to cause that the exhaust temperature is too high and exceeds the allowable working range of the compressor, so that the compressor is frequently started and stopped, the system can not normally work, and the compressor can be burnt down due to the arrangement in severe cases.

And the quiet dish of present compressor often is fixed mounting at the cover top, and for the convenience of installation and maintenance, the casing often comprises casing and cover, through bolt zonulae occludens between casing and the cover, and the junction is sealed through the sealing washer, but the sealing washer is when using, and it is great to receive the temperature variation influence, and no compensation effect leads to sealed not firm.
