| Product Name | ZJQ direct discharge atmospheric vacuum pump |
| Using | Widely used in metal, non-metal material industry vacuum degassing, vacuum melting, vacuum surface treatment and low-density wind tunnel test and electrical equipment, vacuum freeze drying equipment manufacturing and other occasions |
ZJQ series air-cooled Roots vacuum pump is a new product derived from the addition of bypass gas cooling system on the basis of ZJ series Roots vacuum pump. Due to its special structural design, it can operate reliably for a long time under high pressure difference and high compression ratio. The cooling gas enters the suction chamber from both sides of the pump, so that the pump will not overheat due to the compression of the gas, but it has no effect on the pumping performance of the pump. The cooler and motor are necessary accessories for each pump, and the specifications of the cooler and motor are determined according to different working conditions. The pump can be used alone or in series with liquid ring vacuum pump and ordinary Roots vacuum pump to achieve a higher vacuum degree to meet various process requirements.
Main feature
It can be used alone or in series with multiple stages or in series with liquid ring pump.
The working vacuum degree can reach 150mbar when the atmosphere is discharged directly.
Multi-stage series or liquid ring vacuum pump series can reach the vacuum range.
Special structural design to ensure that the high pressure difference and high compression ratio will not overheat overload.
Good dynamic balance test and high-precision machining to ensure smooth and quiet product operation.
Advanced balanced mechanical seal makes the sealing performance of the pump better.
The pump chamber is oil-free structure, suitable for pumping general air and various special gases.
Compared with other mechanical vacuum pumps, the energy saving effect is remarkable.
