Introduction:
JZP2H series Roots-Piston vacuum pump system contains of ZJP series roots vacuum pump and H/2Hseries piston vacuum pump (roots vacuum pump as main pump and the Piston vacuum pump as backing pump).

Advantage:
1.This system has a remarkable energy saving effect.
2.This system has very fast pumping speed during high vacuum pressure range.
3.This system can work well with filter device, if the gas contains small amount of water vapor or dust.
4.This system has the advantages of compact structure and convenient operation.

Application:
It’s widely used in electric power industry of transformer, wire and cable, condenser vacuum impregnation, vacuum drying process. It’s the ideal vacuum equipment for the industry of vacuum coating, vacuum smelting, vacuum heat treatment, vacuum oil filter, freeze drying, aviation simulation test.

Roots and Rotary piston vacuum pump system has a remarkable energy saving effect. It has very fast pumping speed during high vacuum pressure range. It’s widely used in electric power industry of transformer, wire and cable, condenser vacuum impregnation, vacuum drying process. It’s the ideal vacuum equipment for the industry of vacuum coating, vacuum smelting, vacuum heat treatment, vacuum oil filter, freeze drying, aviation simulation test.

It should be equipped with filter device if the gas contains small amount of water vapor or dust.

Roots and Rotary piston vacuum pump system includes two pumps (roots vacuum pump as main pump and the rotary vacuum pump as backing pump). It takes the vacuum relay or electric contact pressure gauge to realize the roots and rotary piston pump’s automatic opening and closing and automatic overload protection.The whole system is installed in one mounting skid, which equipped with pipelines, valves, electrical control box, cooling water pipe system. This system has the advantages of compact structure and convenient operation.

The speed ratio range of each pump is from 4:1 to 10:1 which decided by the vacuum system size and ultimate pressure level. There is a pneumatic solenoid valve in the inlet pipe on the first stage to avoid the oil suction back when pump stops. The pneumatic solenoid valve moves towards with the motor, When the rotary piston pump stops, it pumps inlet gas and ensure the vacuum oil returns to the fuel tank of piston pump preventing the vacuum system from the vacuum oil pollution.
