JZJX series Roots rotary vane vacuum unit

  The jzjx series Roots rotary vane vacuum unit is made up of ZJ-type Roots pump as the main pump, single-stage or double-stage rotary vane pump as the low-level and high-vacuum equipment of the pre-stage pump. The whole set is placed on a rack. With piping, valves and electrical control box, in addition to the minimum specifications, it is also equipped with a cooling water pipe system. The unit is compact and easy to use. When the 2X rotary vane vacuum reaches the limit, the pumping rate is continuously reduced. The ZJ Roots vacuum pump enables the unit to maintain a relatively high pumping rate during extreme vacuum. The JZJX series Roots rotary vane vacuum unit has high vacuum, sustainable operation and low noise.

Note: The performance indicators listed in the table refer to the performance indicators under the following specified conditions.

  1 atmospheric pressure 101325Pa (760mmHg) 2 water ring pump inlet water temperature 15 ° C 3 intake air temperature 20 ° C 4 air relative humidity 70%

  5 The ultimate pressure means that there is no container, and the minimum value of the stable air partial pressure is measured at the inlet of the unit by a compression vacuum gauge after sufficient pumping under the pump port sealing condition. 6 pumping rate refers to the theoretical pumping rate. 7 The front stage pump used is a conventional configuration, and the foreline pump can also be selected according to the actual situation. If the 8 units are automated, the above indicators will change.
