    JZJW Roots-reciprocating pump unit

    Working principle of roots vacuum units

            

    JZJW roots vertical oil-free reciprocating pump unit is made up of the series connected ZJ roots pump and WLW vertical oilfree pump, where the ZJ roots pump is the main pump and the WLW vertical oil-free pump is used as the fore pump. As the WLW vacuum pump adopts the oil-free self-lubricating system, it can obtain the clean vacuum. Thus, after installing a tail gas collection device, it can be able to collect gases that can not be collect through condensation and compression; at the same time, it can avoid the discharge of the great amount waste water produced by the water ring unit.
     

    Range of use


    JZJW type Roots- vertical oil free reciprocating pump unit is connected in series using ZJ Roots pump as main pump and WLW-vertical oil free reciprocating pump as fore pump. It overcomes the low limit pressure and low pumping rate under certain pressure of WLW vacuum pump and at the same time retains the rapid working speed and relatively high pumping rate advantages of ZJ Roots pumps. Therefore, the unit has been widely used for the vacuum distillation, vacuum evaporation, crystallization of dehydration in the chemical industry, the freeze drying in food industry and the vacuum drying process in medicine industry, etc. The application of oil free selflubricating material makes the WLW vacuum pump have access to clean vacuum. Therefore, after equipped with exhaust gas collecting device at the air outlet, the unit could collect the gases which can not be solidified, compressed and collected in the high vacuum system such as pentadiene, benzene, toluene, etc to prevent them from discharging because of their low boiling point and difficulty in collection and polluting the environment.
