The main characteristics of low vacuum unit are high working pressure and large displacement, but its pumping speed is lower than that of high vacuum unit. It is mainly used for the rough pumping of vacuum chamber, vacuum transportation, vacuum impregnation, vacuum filtration, vacuum drying, vacuum degassing (liquid steel treatment) and other equipment with large amount of outgassing and high working pressure.
The main pumps of low vacuum pumping unit are reciprocating vacuum pump, oil sealed mechanical pump, dry mechanical pump, water jet pump, steam eruption pump, water ring pump, molecular sieve adsorption pump, wet roots pump and other direct discharge atmospheric vacuum pumps. The use of low vacuum pumping unit also needs to be equipped with necessary dust remover and water gas separator according to the cleaning degree, humidity or other special requirements of the extracted gas Oil water separator, dry bath well and other parts.
