Cottle compressor works brief single-stage compression screw compressor are parallel to each other by a pair of yin and yang rotor teeth together (or screw) Cottle compressor rotation in the cylinder, so that the rotor slots air is continuously generated between the periodic change in the volume, the air along the suction side of the rotor axis by a conveyor to the output side, to realize the screw compressor suction, compression and exhaust of the whole process. Air compressor inlet and outlet are on opposite sides of the housing of the female rotor and the male rotor grooves teeth are driven to rotate the main motor. Directly driven by the electric motor of the compressor, so that the crankshaft rotational motion of the piston rod driven reciprocating motion, causing the cylinder volume change. Due to changes in pressure within the cylinder by the air intake valve through the air filter (*) into the cylinder during the compression stroke, since the cylinder volume is reduced, the role of compressed air through the exhaust valve, through the exhaust pipe, a single the valve (check valve) into the tank, when the discharge pressure reaches the rated pressure 0.7MPa controlled by a pressure switch and automatic shutdown. When the tank pressure dropped 0.5--0.6MPa pressure switch automatically joins start. Air compressors have anything to do with cleanliness? Because of the role of wind in the air, always contain different levels of dust and other impurities in the air if too gray sand impurities, the compressor has considerable harm. Endanger the following points: 1, sand quite hard wear of the cylinder, piston rings, piston fillers and other parts, shorten the life of the machine; 2, the dust mixed with the lubricating oil into the cylinder compressor Qin Wei, cylinder, piston will form the focus ring block, on the one hand impede machinery lubricated air compressor prices, causing pull-cylinder, Calatrava; on the other hand in the compressor high temperature, sand and more cases could cause an explosion; 3, gray sand into the compressor easy clogging valve, a cooler, air lines and pneumatic machinery, resulting in the compression device is not tight, so as to reduce air flow; 4, since the dust will increase the wear of the compressor, lubrication of the compressor damage, influence of the cooling gas, so that compressed gas The final temperature increased air compressor, power consumption will also increase dramatically. Therefore, before the air or other gas enters the compressor must be equipped with controllable filter device, to prevent dust and impurities into the cylinder, to prevent relative sliding movement of the wear member has a sharp increase, oxidation of the lubricating oil can be prevented.
