Introduction:
ZJZBA series roots-water ring pump system connected a roots vacuum pump as its main pump and a backing pump (water ring vacuum pump).
Equipped with a water ring pump as its backing pump, this system has successfully overcome some shortages for separate water ring pump application. Such as low ultimate vacuum in usage, slow pumping speed in certain vacuum degree. Simultaneously, the advantages like high pumping capacity and fast start-up time for roots pump has been remained. Another note, this system can pump a large amount of condensable vapor. This trait will be more obvious especially when the gas contains too much vapor to be pumped by gas ballast oil-sealed mechanical pump, or the pump performance is influenced when pump oil exacerbated by the pump oil, or oil pollution is impermissible for the vacuum system. Matching with an anti-explosive motor and properly operated, explosive gas can be pumped by this system.
Application:
JZJBA series roots water ring vacuum pump system is widely used in the chemistry industry, such as below process: vacuum distillation, vacuum evaporation, dehydration and crystallization, etc. And the system is also required by following industry and process, freezing and drying in food industry, vacuum drying in medical industry, stripe slicing in light textile industry, high-altitude simulation test in vacuum system.
