Product Description
JZJS Series Roots Vacuum Pump Set
Overview
JZJS roots vacuum set is made up of the series connected roots pump and liquid ring pump, where the roots pump is the main pump and the water ring pump is used as the backing pump.
It overcomes the ultimate pressure difference when using a single liquid ring pump (compared with the liquid ring pump, the ultimate pressure of the unit is greatly improved), and the low pumping rate under a certain pressure, at the same time, retaining the advantage of the fast work and higher pumping rate of the roots pump. In particular, it is adapt to pump a great amount of condensable vapors.
Roots water ring vacuum system includes the following types:
(1) Roots pump-water ring pump: The liquid ring pump in this unit is used to produce the fore vacuum required for the roots pump. Generally, the ultimate vacuum degree of the single-stage water ring vacuum pump is not high, and the roots pumps require higher ultimate vacuum degree, thus, the single-stage liquid ring pump is not usually used as the backing pump of the roots pump. The two-stage water ring pump with lower ultimate pressure can be applied as the backing pump, to reduce the ultimate pressure of the unit.
The ultimate pressure of one roots pump and one water ring pump is 400PA, which can meet the general needs of vacuum. If combine two series connected roots pumps and the water ring pump, the ultimate pressure can be greatly increased (up to 25PA). Therefore, for this type, the combination of two series connected roots pumps with a two-stage pump as the backing pump is common to compose the unit. If need a higher ultimate pressure, a combination of three roots pumps with a liquid ring pump can be used, which ultimate pressure can be up to t 1PA.
(2) If the three-stage roots liquid ring unit can not meet the ultimate pressure, the roots pump-water ring pump parallel mechanical vacuum pump can be adopted; This unit is mainly for a vacuumizing system which is used to treat a great amount of water vapor, and requires a long time and a very high ultimate vacuum degree, e. G, in the vacuum drying area.
In the vacuum system which is used to treat a great amount of water vapor, liquid ring pump is more appropriate choice. However, its ultimate vacuum degree is not high, as a result, the ultimate vacuum degree of the entire unit is lower (relatively).
Although in the vacuumizing system requiring higher vacuum degree, the mechanical vacuum pump of higher ultimate vacuum shall be used as the backing pump, the gas ballast mechanical vacuum pump and water-ring pump can be connected in series to act as the fore pump of the roots pump. In vacuum drying, first use the liquid ring pump for backing pumping until there is a significant reduction in water vapor, and then switch on the gas ballast mechanical vacuum pump, and switch off the water ring pump.
Applications
Roots pump-water ring pump system is widely used for the vacuum distillation, vacuum evaporation, dehydration and crystallization in the chemical industry; Freeze drying in the food industry; The vacuum drying in the pharmaceutical industry; The terylene section cutting in the light textile industry; The vacuumizing system in high-altitude simulation test, and so on.
