Customized vacuum unit
DP oil-free screw vacuum pump unit, environmental protection and energy saving
working principle:
Dry screw vacuum pump is an air extraction device that uses a pair of screws to perform synchronous high-speed reverse rotation in the pump casing to generate suction and exhaust. The two screws are corrected by fine dynamic balance, supported by bearings, and installed in the pump. In the shell, there is a certain gap between the screw and the screw, so when the pump is working, there is no friction between each other, the operation is stable, the noise is low, and the working chamber does not need lubricating oil. Therefore, the dry screw pump can remove a large amount of water vapor. In the case of gas with a small amount of dust, the ultimate vacuum is higher, the power consumption is lower, and it has the advantages of energy saving and maintenance-free. It is the replacement product of oil-sealed/water-ring/jet vacuum pump.
2. Main Features
l The single-stage design can obtain a high vacuum of 1Pa, and can operate continuously for a long time from the atmosphere to the ultimate vacuum
l The screw is made of integral ductile iron, with high strength and good reliability
l Oil-free dry compression, which can extract condensable gases, toxic and harmful gases
l The running parts inside the suction chamber have no contact friction, which can achieve high-speed and smooth operation
l Internal parts can be treated with anti-corrosion coating, which can be applied to the special requirements of the chemical and pharmaceutical industry
l Low noise, no vibration, suitable for use in quiet environments such as microelectronics and semiconductors
l Oil-free structure design of pump cavity, no exhaust gas and no waste liquid discharge from the pump, especially suitable for gas recovery
l It can be combined with Roots vacuum pump, air-cooled Roots vacuum pump and molecular pump to form high vacuum obtaining equipment
