Product Description
ZJQ series air-cooled Roots vacuum pump
ZJQ series air-cooled Roots vacuum pump is improved on the basis of ZJ series Roots vacuum pump, adding bypass gas cooling system.
The rotor and pump chamber are cooled by gas so that they do not produce high temperatures at high pressure differences.
In general, heat exchangers are installed in the exhaust port or return line of the pump.
The gas discharged from the exhaust port is cooled by the heat exchanger, and the cooled gas enters the pump chamber from both sides of the pump body and cools the rotor and the pump chamber, but it has little effect on the pumping performance of the pump.
Pump can be used alone, can also be used in series, can be connected with liquid ring vacuum pump, reciprocating vacuum pump, slide valve vacuum pump, etc., to achieve higher vacuum degree and greater pumping speed to meet the needs of the process, energy-saving effect is remarkable.
Product advantage
Summary of Product advantage
1.Can be used alone, the working vacuum degree of direct exhaust atmosphere can reach 15-20kpa.
2.It can be connected with the front pump to form Roots unit in series, and the different ratio can obtain 105 ~10-2 pa, which has remarkable energy-saving effect.
3.There is no friction in the running parts of the pump, no need for lubrication, no oil in the pump chamber, and clean vacuum can be obtained.
4.Three-leaf plum blossom line structure and high-precision machining ensure smooth and quiet product operation.
5.Air extraction performance, noise, vibration and other main performance is significantly improved than the traditional two-blade rotor.
6.The gas in the pump chamber flows vertically, which is conducive to the removal of dust and condensate in the pumped gas.
7.Wide application range, can work under higher inlet pressure.
8.The motor power is uncertain, and the maximum pressure difference during actual operation needs to be calculated according to the process conditions to determine the required motor power.
