Description

Technical Field

[0001] The invention relates to the technical field of compressors, in particular to a vertical fully enclosed screw compressor. Background Art

[0002] The screw compressor is a rotary compressor that compresses and delivers gas by rotating a screw-shaped rotor in a cylinder. The screw compressor is the core component of the entire system and is a type of positive displacement compressor. The compression of gas is achieved by the volume change of the teeth of the yin and yang rotors that are parallel and meshed with each other in the casing. The rotor rotates in the casing that precisely matches it, causing the gas between the rotor teeth to continuously produce periodic volume changes, pushing from the suction side to the discharge side, completing the three working processes of suction, compression, and exhaust. At present, the semi-enclosed screw compressors in the prior art have the following problems: the oil flow cannot be adjusted, causing excessive oil injection to cause the compressor power to increase and the volumetric efficiency to be low, and too little oil injection will cause the compressor to be insufficiently lubricated, easily stuck with the shaft, and cause the compressor to burn out.

It has the function of automatic oil flow regulation, which can prevent excessive oil from entering the compression chamber and reduce power consumption; the self-sensing content volume ratio is automatically adjusted to eliminate over-compression and under-compression and improve compression efficiency; an efficient vertical oil seal is realized to provide an exhaust gas with a very low oil content for the refrigeration system, thereby improving the overall efficiency of the system.
