Title:
GAS DISCHARGING BEARING SEAT AND SCREW COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2017/219758
Kind Code:
A1
Abstract:
A gas discharging bearing seat and a screw compressor comprising the gas discharging bearing seat are provided. The gas discharging bearing seat comprises a bearing seat body (1). An end surface of the bearing seat body (1) is provided with a gas supplementation port (2). The bearing seat body (1) is further provided with a gas supplementation pulse attenuation chamber (3) communicating with the gas supplementation port (2). A volume of the gas supplementation pulse attenuation chamber (3) is greater than a volume of the gas supplementation port (2). The bearing seat body (1) is provided with the gas supplementation pulse attenuation chamber (3) communicating with the gas supplementation port (2), such that during gas supplementation, low frequency vibrations caused by the gas supplementation port (2) are superimposed on each other in the gas supplementation pulse attenuation chamber (3), and therefore gas pulses caused by the gas supplementation port (2) are attenuated in the gas supplementation pulse attenuation chamber (3), thereby reducing gas pulses caused by gas supplementation, reducing vibrations and noise of a gas supplementation pipeline of a screw compressor, and improving reliability of the screw compressor.
