Screw vacuum pump is a pair of screws, in the pump chamber of screw vacuum pump for the synchronous reverse direction of the high-speed operation. When the studio volume in the pump chamber becomes more small and connected with the inlet pipe of the pump, the gas enters the pump suction chamber until the suction chamber is larger and again separated from the air inlet. When the volume decreases, the gas is compressed until the pressure of the gas is greater than one atmospheric pressure and the exhaust valve is opened to drain the gas.

The vortex compressor is a dynamic and static vortex disk with two double function equation lines biting into each other. In the process of suction, compression and exhaust, the static disc is fixed on the rack, and the moving disk is driven by the eccentric axis and restricted by the anti-rotation mechanism, rotating around the center of the static disc base circle with a small radius. The gas is inhaled into the periphery of the static disc through the air filter element. With the rotation of the eccentric axis, the gas is gradually compressed in several crescent compression chambers composed by the agage of the static disc, and then continuously discharged by the axial hole of the central component of the static disc.

Single screw air compressor is a rotor screw with six grooves on an outer cylindrical surface, with exactly the same 11-rack planetary gears mounted vertically on the left and right sides of the screw. When working, the screw drive two planetary gear rotation at the same time, owing to the planetary gear rack and screw groove is engaged, so in operation, planetary gear rack around its shaft on the one hand, another aspect gradually immersed in the screw groove and the screw groove volume gradually reduced, to achieve the purpose of compressed gas.

The operation principle of the screw blower is that two parallel Yin and Yang rotors engage each other in the "∞" shaped cylinder to form the working volume. Through the synchronous gear, the rotor rotates at high speed. With the size of the working volume of the rotor, the gas compression is realized in the process of gas transmission. The working cycle of the screw blower can be divided into three processes: suction, compression and exhaust.

Oil-free medium and high pressure air compressor is an air compressor set in series between low pressure screw machine and medium pressure piston machine. First of all, the screw machine is used as the front machine to provide a pressure pressure, after a certain pressure, and then through the piston machine pressurization, to achieve the set volume flow and exhaust pressure.

Freeze drier is according to the principle of freezing and dehumidification, the compressed air is forced through the evaporator for heat exchange and cooling, so that the gaseous water and oil in the compressed air through isovoltage cooling, condensation into liquid water and oil, and with dust, through the automatic drain discharge system, so as to obtain clean compressed air.

The adsorption dryer is through the "pressure change" (pressure change adsorption principle) to achieve the drying effect. Because the ability of the air to hold water vapor is inversely proportional to the pressure, the dry part of the air (called regas), pressure expansion to atmospheric pressure, the expansion air more dry, and then let it through the unconnected air regeneration desiccant layer (which has absorbed enough water drying tower), the dry water in the desiccant, take it out of the dryer to achieve the purpose of dewetting.
