  Summary:

  ZJQ Series air-cooling roots vacuum pump is in ZJ Roots series vacuum pump based on the increased bypass gas cooling system is designed. Because of its special structural design, make its can run reliably for a long time under the high pressure. Under normal circumstances are in the pump outlet or back flow are installed in the piping for heat exchanger. Cooling gas from both sides of the pump body into the pump cavity and cooling of the rotor and the pump cavity, but the pump pumping performance did not affect. Pump can be used alone can also multiple used in tandem, or with liquid ring vacuum pump in series to form a unit and achieve higher vacuum degree to meet the technological requirements.

 

  ZJQ Roots series vacuum pump has the following characteristics:

.Enable to be directly discharged into the atmosphere, no waste water discharge;

.Enable to be connected in series with the former pump composed of Roots unit, energy saving effect is remarkable. Compared with the ordinary Roots pump, the ZJQ Roots pump vacuum can work under high pressure difference, can appropriately reduce the fore pump so as to achieve energy saving effect.

.Wide range of application. Due to the exhaust side can withstand high pressure, effectively solve the ordinary vacuum pump Roots pressure difference is too large, the vacuum degree of the former pump caused by overload, overheating;

.Enable to work under higher inlet pressure series.ZJQ air cooled vacuum pump Roots theory can work under the condition of the entrance to the atmospheric pressure;

.The motor power is not sure series.ZJQ Roots pump vacuum the calculation of the actual working conditions according to the calculation of the maximum differential pressure in order to determine the required motor power.
