JZJG/JZJGP Type Roots Screw Vacuum Unit
Summarize
JZJG/JZJGP series Roots screw dry vacuum unit is a dry oil-free vacuum unit composed of ZJ type Roots pump as the main pump and NEG/NEGP series screw vacuum pump as the front pump. After the first stage screw vacuum pump works, the vacuum gauge and vacuum relay control the starting of Roots pump.
Main feature
1, there is no oil in the pump chamber, no pollution to the pumped system, and clean vacuum can be obtained.
2, there is no oil in the pump chamber, and it is very easy to recover the solvent.
3, Roots pump pump chamber and screw pump pump chamber are plated sickle or infiltration alloy coating treatment, can be extracted water vapor, solvent gas and other corrosive media.
4, because the main pump and the previous pump are oil-free dry vacuum pumps, no waste water, waste oil discharge is pollution-free to the environment.

Instructions:
1. The above table recommended standard series, but in the actual production process can be based on different working conditions, such as the actual pumping process, gas release process, condensable gas cold coagulation, suction pressure time ratio, etc., to check the calculation or select the type with reference to the original equipment use.
2. The technical indicators of a single pump are detailed in each pump parameter table.
3.When setting the pump, please explain the technical requirements such as pumping medium, working pressure, and explosion-proof requirements.
