Air compressor is mainly used for fire, marine, marine seismic, pipeline testing, valve testing, leak detection, plastic molding, oil field chemicals, ships, military and other industries, in all applications, the most widely used in industrial fields. The reason is so widely used in air compressor industry, mainly produces compressed air compressor has the following advantages: (1) easy storage. Easy storage of a large capacity as required compressed air. (2) design and simple control. Acting pneumatic components are simple design, thus suitable for simple control of the automated system. Select (3) movement. Pneumatic components and easy to implement variable speed linear and rotary motion. (4) the compressed air system. Because the price is right pneumatic components, the entire device relatively low cost and long life of pneumatic components, so lower maintenance costs. (5) Reliability. Pneumatic components have a long working life, so the system has a high reliability. (6) harsh environment adaptability. Compressed air is largely unaffected by temperature, dust, corrosive effect, it is the other systems can not reach. (7) Environmental clean. Pneumatic components are clean, and people with special exhaust air treatment methods well-known manufacturer of air compressors, less environmental pollution. (8) Security. Will not cause a fire in dangerous places, if the system is overloaded actuator will stop or slipping. 2, cleaning minimum pressure valve (screw compressor, also known as pressure maintaining valve) minimum pressure valve from the valve body, valve, adjusting nut, springs, sealing elements and other components. Mainly from the establishment of minimum pressure valve pressure inside the unit, prompting the oil circulation to meet the offloading valve operating pressure and so on. Also the minimum pressure valve can also play the role of a one-way valve air compressor manufacturer, to prevent run-time crew unloading the tank of compressed air back to the compressor. Removal (1) The minimum pressure valve: minimum pressure valve structure is very simple, unscrew the nut between the spool valve can be removed and the inside of the device, a small unit of the minimum pressure valve body is built into the body, which open valve cover to remove all internal components. (2) Cleaning minimum pressure valve: Press the purge valve unloader cleaned minimum pressure valve. (3) The minimum pressure valve assembly: a reverse steps to remove the assembly components, since the minimum pressure valve structure is very simple, the assembly process is not to recount compressor manufacturers offer, but be aware that, as an internal U-ring Please pay attention to the direction of U-rings. (4) The minimum pressure valve after the cleaning process is complete aside to be loaded into the compressor.
