Principle description of JZJW Roots Vacuum Unit
JZJW Roots vertical oil-free reciprocating pump unit is composed of ZJ Roots pump as main pump and WLW vertical oil-free pump as backing pump in series. Since WLW vacuum pump uses oil-free self-lubricating system and can obtain clean vacuum, after installing tail gas collecting device, gas which can not be solidified and collected can not be compressed in high vacuum system can be collected, and large amount of waste water produced by water ring unit can be avoided.
