2XZ two-stage rotary vane vacuum pump

1、 2XZ type direct coupled rotary vane vacuum pumpOverview

2XZ typeRotary vane vacuum pumpDouble stage high-speed direct connection structureRotary vane vacuum pump(hereinafter referred to as the pump). It has a rotor eccentrically installed in the pump chamber and rotor blades in the rotor slot. When the rotor drives rotation, the rotor tightly adheres to the chamber wall, separating the intake and exhaust ports, and periodically expanding the volume of the intake chamber to suck in air, while periodically reducing the volume of the exhaust chamber to compress gas, pushing open the exhaust valve to exhaust, thereby obtaining vacuum. Figure 1 is a schematic diagram of the working principle of a single-stage pump. Double stage is composed of two single stages connected in series.
The 2XZ pump is equipped with a pneumatic valve, which has the function of prolonging the use time of pump oil and preventing pump oil from mixing with water.
The 2XZ pump has the advantages of small size, light weight, low noise, and easy starting. In addition, there are measures to prevent oil return (not available for 2XZ-8) and measures to prevent oil seal leakage from contaminating the site.

2、 2XZ type direct coupled rotary vane vacuum pumpMain purpose:

1Rotary vane vacuum pumpIt is a basic equipment for obtaining vacuum, which can be used alone or as a pre pump and pre pump for various high vacuum systems.
2. The pump inlet shall operate continuously with open air for no more than three minutes.
3. Pumps are not suitable for extracting gases that are corrosive to metals, react chemically with pump oil, contain particulate dust, or contain explosive gases with high oxygen content.
4. Pumps shall not be used as compression pumps or delivery pumps.
5. The working environment of the pump: within the temperature range of 5 ℃ -40 ℃, with a relative temperature not exceeding 90% and an inlet pressure less than 1333Pa, it is allowed to operate continuously for a long time.
6. When installing the power supply, follow the instructions on the motor label and pay attention to the direction of motor rotation and the direction of the arrow on the support.
7. The diameter of the pipeline for continuous pumping of containers should not be less than the inlet diameter of the pump, and the pipeline should be short and have fewer bends, while paying attention to pipeline leakage.
8. Before starting each time, pay attention to checking the oil level, and it is advisable to fill the oil to a height of 4/5 of the diameter of the oil gauge glass when stopping the pump.
9. The pump oil used is clean SY1634-701 vacuum pump oil.
10. The pump can be started once under atmospheric or any vacuum level. If the XZ-1 single-stage pump has difficulty starting, the intake pipe plug cap can be removed to start and then put into operation.
