A Hermetic Scroll Compressor For Application To High Heat Of Compression Gases
A horizontal hermetic scroll compressor has been developed for applications with high heatof-compression gases, including natural gas, air and helium (cryogenics). The compressor is a low profile horizontal design with oil-flooded cooling of the compression process. Combined with components required for oil separation and cooling, this design provides a smooth, continuous compression process fe...

متن کاملThe Design of a Small Oil-Flooded Rotary Air Compressor
There have in the past been few successful small oil flooded rotary air compressors, due in the main to the cost of manufacture and the problem of internal condensation with intermittent operation. The paper describes a new approach to overcoming these problems, and reports a successful outcome.
متن کاملHow to limit fire and explosion hazards with oil-flooded rotary screw compressors
From 1973 through 1986, a total of 12 fires involving oil-flooded rotary screw compressors (OFRSC) were reported to the Mine Safety and Health Administration (MSHA). Most of these incidents were attributed to faulty or bypassed safeguards, or improper maintenance. The cause of a fire in an OFRSC is unique when compared to other types of compressors. A compressor inspection checklist is provided...
متن کاملAn Experimental Study of the Shaft Oil Supply Mechanism of a Rotary Compressor
This paper describes the experimental study of the shaft oil feed mechanism of a rotary compressor. The oil contained in the shaft in which an oil pump is inserted is fed to the respective sliding surfaces of the subbearing section, eccentric section and main bearing section of the shaft by centrifugal force of shaft rotation. The oil feed pressure of shaft rotation is approximately 0.1 kg/cm2 ...
