Classification Of Vacuum Units

Vacuum unit is generally named according to the type of main pump, and then can be classified according to product characteristics, such as oil-containing vacuum unit and oil-free vacuum unit; more commonly, according to the scope of vacuum application, can be divided into low vacuum unit, medium vacuum pump unit, high vacuum unit and ultra-high vacuum unit.

The four categories of vacuum units :

Low vacuum unit has high working pressure and large exhaust capacity, which is mainly used for vacuum conveying, vacuum impregnation, vacuum filtration, vacuum degassing of vacuum dryer, etc. Reciprocating pumps, water ring pumps, oil seal mechanical pumps, screw vacuum pumps, wet roots pumps, jet pumps, molecular sieve adsorption pumps and other types of vacuum pumps commonly used in low vacuum units can be competent, but according to the cleanliness, humidity and other conditions of the exhausted gas, it is necessary to configure the excluding Dust, gas, water, oil and water separator, drying trap and other facilities.

Medium vacuum unit is suitable for all kinds of vacuum systems which need large pumping speed and obtain medium vacuum, such as coating machine, vacuum smelting, vacuum heat treatment, medicine and chemical industry, electrical welding and so on. In the past, the combination of Roots Vacuum Pump + Oil Seal Mechanical Pump, Roots Vacuum + Water Ring Vacuum Pump and Double Roots Vacuum Pump was the most common vacuum unit. With the rise of oil-free vacuum pump such as screw vacuum pump, Roots vacuum pump + screw vacuum pump such as oil-free vacuum unit has gradually increased, more adaptable.
