Double screw rod compressor

Abstract

The invention discloses a double screw rod compressor. The double screw rod compressor comprises a female rotor, a male rotor, an exhaust pipe, a sliding valve and a control assembly. The female rotoris located on the upper end of the male rotor, the exhaust pipe is located between the female rotor and the male rotor, the sliding valve is located at one end of the exhaust pipe, the control assembly is located on the periphery of the female rotor or the male rotor and can be used for driving the sliding valve to move left and right, and the control assembly is fixedly connected with the sliding valve through a sliding valve rod. The double screw rod compressor can ensure sliding valve stability, the compressor stably runs, meanwhile, the noise of the compressor can be effectively reduced,and the problems that due to the fact that a gas vortex pushes the sliding valve, consequently, the sliding valve is not stable, the compressor is frequently loaded and unloaded, and whole compressorabnormal protection is caused can be solved.

Description

Technical field [0001] The present invention relates to the technical field of compressors, in particular to a twin screw compressor. Background technique [0002] With the development of air conditioning technology, twin screw compressors have been widely used in the field of commercial air conditioning due to their high reliability, strong dynamic balance, small footprint, high volumetric efficiency, and simple structure. The existing twin-screw compressors have problems such as poor automatic loading stability and high noise. At present, achieving stable control of automatic loading of screw compressors and reducing noise are technical problems in the design and manufacture of screw compressors. The stability of automatic loading directly affects the performance and reliability of air conditioning units, and noise issues directly affect user evaluation of compressors. An important factor for good or bad. Therefore, improving the stability of the compressor and solving the no...

AI Technical Summary

Problems solved by technology

[0003] At present, the main reasons for the problems of poor automatic loading stability and high noise in twin-screw compressors are: (1) The sealing effect in the oil piston chamber is not good, and the oil pressure in the oil piston chamber fluctuates, so that the oil piston and slide valve cannot be stabilized at Set the operating load; (2) When the gas after the meshing of the male and female rotors flows to the exhaust pipe through the bent pipe, the vortex of the air flow will push back the slide valve. The compressor cannot run stably under the set load; (3) The gas after the meshing of the male and female rotors flows to the exhaust pipe through the bent pipe, and the air flow bends and flows, resulting in loud noise
