Improvement of the Reliability of a Single Screw Compressor
The correct design of the engagement pair (mainrotor and gaterotor) profile is the foundation to improve the operating reliability of a single screw compressor. An introduction to take a straight line enveloping pair as the engagement pair of the main machine is presented after analysing the present engagement pair. A complete analysis is also made of the hydrodynamic lubrication property and i...
متن کاملEfficiency Improvement in Rotary Compressor
This paper presents how we improved the efficiency in rotary compressor. At first, we made effort to estimate the power losses in the compressor, to analyze the operating conditions of the bearing and to calculate the performance of the compressor. Next, the temperature in housing and pressure in cylinder were measured in real compressors in order to obtain the data on the internal conditions o...
