2XZ series rotary vane vacuum pump is a double stage high speed direct coupling structure rotary vane type vacuum pump, which is the basic equipment used to pump gas of the sealing container. Pump cavity is provided with a rotor, the rotor slot with rotary vane. The rotor drives the rotary vane rotation, the rotary vane close to the chamber wall and separated air inlet port from the discharge port, and the air inlet area of cavity volume is periodically enlarged and inhale, discharge chamber volume is periodically reduced and compressed gas, open the exhaust valve to exhaust gas and then to obtain vacuum. Its working performance is composed of two parts, the high level and low level. Its suction is connected with vacuum equipment, when in operation The gas in container will have a large number of suction and discharge, when the equipment got vacuum, high pressure grade exhaust valve is closed, high-pressure grade inlet gas will be transferred to the second level, and through the second stage suction and discharge vacuum equipment, it can obtain a certain vacuum. Pump connecting shaft with motor, high speed, small appearance, compact structure, convenient mobility work.

Pumping rate: 0.25~30L/S

Gas type: Clean dry air without any other mixture at ambient temperature.

Working requirements:

When the inlet pressure is greater than 6500Pa, continuous working hours must not be more than 3 minutes so that avoid fuel injection to damage pump.

When the inlet pressure is less than 1330pa, it is allowed to work continuously for a long time.

Ambient temperature: 5℃-40℃, the relative temperature is not higher than 90%.
