The main components of the screw compressor is a screw head, oil and gas separation barrel. Screw head through the suction filter and the intake control valve intake air compressor manufacturers supply, while oil into the air compression chamber, cooling of the nose, sealed and lubricated bearings for screw and the compression chamber to produce compressed air. Compressed air mixture gas emissions generated to oil and gas separation barrel, due to mechanical centrifugal force and gravity, the vast majority of the oil is separated from the mixture of oil and gas. Air passes through the borosilicate glass fiber made of oil and gas separation tube core, almost all of the oil mist are separated. From oil and gas separation tube core separated oil back through the return pipe inside the screw head. Equipped with an oil filter in the return pipe back to the oil through the oil filter, clean the oil was flowing back into the screw head. When the oil is separated from the compressed air through the minimum pressure control valve and gas cylinder into the cooler after leaving. After cooling the compressed air is cooled back to the air tank for each gas units. Condensed out of the water is concentrated in the air tank, automatic or manual drain discharge. Generating compressed air from the air compressor is not pure. This is because the air compressor itself contains lubricating oil, during the compression work, there must be part of the lubricating oil mixed into the air to go. Also the nature of air itself contains the function and method role in cleaning the air compressor head: air compressor long time, there will be internal grease, soot-made air compressor manufacturers, sediment, rust. Also used different brands of air compressor oil, there will be vinyl material like asphalt. Therefore it is necessary to periodically use cleaning agents, the head of air compressor manufacturers, paint bucket, radiator Cottle compressor manufacturers, tubing internal cleaning something. Thereby eliminating the security risks. Methods: The first compressor running a few minutes, the oil reaches room temperature; close air compressor, and other internal pressure diarrhea finished, open the fuel cap, pour cleaning agents, tighten the fuel filler cap; open air compressor to run for 30 minutes; let go of old oil, then add new oil. After cleaning the air compressor temperature drop of at least about 10 degrees around Kunming compressor manufacturers, Qin Wei air pressure, compressor manufacturers Which is provided by Compressor Co., Ltd. Xianyang Qin Wei. Xianyang Qin Wei Compressor Co. (www.xykyj.cn/) is Xianyang, compression, separation equipment leader, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
