With advances in environmental technology, energy saving, stable and durable low-noise oil-free compressor, are widely in industrial manufacturing, laboratory analysis, technology communications, petrochemicals, environmental protection, energy, health care, aerospace technology, printing and many other industries Applications. Thus, routine maintenance and the general failure on mute oil-free compressor maintenance problems more and more users attention. 1. Choose before purchase. Choose good quality, suitable equipment will be required to use a lot less trouble. 1.1 When choosing large air compressor manufacturer, should require manufacturers to provide as detailed technical parameters, those parameters identified incomplete manufacturers, the lack of detection of certain technology projects, the choice should be careful. 1.2 In accordance with equipment needs and select the flow slightly larger model, to avoid fatigue machine running. Increase the service life of the machine. How to work the screw compressor air into energy to meet the needs of the process of production of well-known compressor manufacturers, I believe many friends curious to know a friend of a large, so Xiaobian special collection of relevant information, the solution for everyone confusion. Screw air compressor closed and delivery process: primary and secondary two rotors at the end of inspiration, the main and auxiliary rotor teeth and the casing of closing of the summit, when the air is no longer in the tooth groove of closing of the outflow, that is, [the closure process]. The rotors continue to rotate the tooth and tooth groove in peak inspiratory end anastomosis surface gradually moving towards the discharge end, namely the transportation process. Compression and injection processes: in the transportation process, the engagement surface and gradually move toward the exhaust side, that is between the tooth groove engagement between the surface and the exhaust port is gradually reduced compressor manufacturers build, tooth groove of the gas gradually It is compressed, the pressure increase, namely the compression process. But also because the compression and the lubricant oil pressure difference and the compressed air is injected into the mixing chamber and the chamber. Exhaust process: When the engagement end surface of the rotor is connected to the exhaust and chassis, when the compressed gas of the highest pressure. The compressed gas begins to drain until the engaging surface of teeth and tooth groove is moved to the peak discharge face, this time with two rotors engaging surface casing vent this tooth groove space zero air compressor manufacturer, complete exhaust process, in the meantime tooth groove length of the rotor and the housing engagement surface between the air inlet and the longest, but also during its process of breathing.
