Vacuum pump unit Under normal circumstances, the use of water ring vacuum pump as the foreline pump is more advantageous than other vacuum pumps, mainly because it can remove a large amount of condensable steam, especially when the gas ballast mechanical vacuum pump removes condensable steam. Insufficient capacity, or the use of solvents can make the pump oil deteriorate and affect performance, or when the vacuum system does not allow oil contamination.

Roots pump + water ring pump = vacuum pump unit, which is widely used in vacuum systems for chemical, food sublimation, high-altitude simulation tests. There are roughly the following types of such combined units.
Roots pump + water ring pump: The function of the water ring pump in the unit is to create the required vacuum for the Roots pump. Therefore, the maximum allowable exhaust pressure of the water ring pump is required. That is to say, on the one hand, the water ring should be raised as much as possible. The ultimate vacuum of the pump, on the other hand, also seek to increase the maximum allowable discharge pressure of the Roots pump.
In general, the ultimate vacuum of a single-stage water ring pump is not high, but the pre-vacuum required by the Roots pump produced in China is higher now. Therefore, the single-stage water ring pump is not used as the fore pump of the Roots pump. A two-stage water ring pump that can increase the ultimate vacuum is used as a foreline pump. A two-stage water ring pump can also be used to increase the ultimate vacuum of the unit.
The ultimate vacuum of a Roots pump is low, especially when it is combined with a water ring pump, the range of use is limited, the ultimate vacuum of the whole unit may be lower, but if two Roots pumps are connected in series Combined with the water ring pump, the ultimate vacuum of the unit can be greatly improved.
Roots pump + water ring pump = vacuum pump unit Roots pump + rotary vane pump = vacuum pump unit Roots pump + reciprocating pump = vacuum pump unit Roots pump + dry pump = vacuum pump unit different environments, different working conditions have different Requirements, when choosing a vacuum pump unit, you must refer to the actual working conditions and environment, and choose your ideal vacuum pump unit.
