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) rotates in the cylinder, the air between the rotor slots continue to produce cyclical changes in the volume of air is transported along the rotor axis from the suction side to the output side, to achieve screw air compressor intake, compression and exhaust 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. Since the in-cylinder pressure change compressor maintenance, by the air intake valve through the air filter (*) into the cylinder during the compression stroke Qinwei air compressor, due to the cylinder volume is reduced, the effect of compressed air through the exhaust valve through the exhaust pipe, the check 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. Classification and definition of Cottle compressor as shown in Figure 1. Classification 2. Definitions 2.1 displacement compressors: air compressor by displacement of moving parts, so that the order of a certain volume of gas inhaled and send the enclosed space to increase static pressure compressor. 2.2 shaft driven reciprocating compressor: the rotational movement of the shaft due to the motion member in the compression chamber for reciprocating linear motion to achieve compression of the suction gas and the volumetric compressor. 2.3 Rotary Compressor: a positive displacement compressor, a member whose movement is movement in a cylinder or several rotor. By displacement volume slider, one or more engagement parts compressor price, or the movement of the rotor itself is achieved. 2.4 powered compressors: With continuous gas inlet to the outlet, its kinetic energy is converted to potential energy of a compressor to increase gas pressure. 2.5 turbine compressor: a rotary vane wheel impeller power compressors. 2.6 Axial turbine compressor: converting the kinetic energy of the turbine compressor is basically bladed axial flow rotary wheel and the diffuser. 2.7 runoff turbine compressor centrifugal compressor that: convert energy turbine compressor is essentially radial flow impeller and diffuser in. 2.8 Ejector: no moving elements, auxiliary fluid system by converting the kinetic energy to achieve compression power compressors.
