2XZ Rotary Vane Vacuum Pump

2XZ Rotary Vane Vacuum Pump--Product overview

2XZ Rotary Vane Vacuum Pump is a two-stage high-speed direct connection structure rotary vane vacuum pump. It has a rotor eccentrically installed in the pump cavity and a rotary vane in the rotor slot. When the rotor drives the rotary vane to rotate, the rotary vane closely adheres to the cavity wall, separates the inlet and exhaust ports, and makes the volume of the intake accumulating cavity periodically expand and inhale, and the volume of the exhaust cavity periodically decreases. Compress the gas and push open the exhaust valve to exhaust, thereby obtaining a 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.

2XZ Rotary Vane Vacuum Pump is a two-stage direct connection structure. Its working performance is composed of two parts: a high-pressure stage and a low-pressure stage. Its suction port is connected with the vacuum equipment, and a large amount of gas in the container is sucked and discharged during operation. When the equipment obtains vacuum, the high-pressure stage exhaust valve is closed, and the gas at the high-pressure stage inlet will be transferred to the second stage, and a certain vacuum can be obtained through the second stage suction and discharge from the vacuum equipment. The technology of the 2XZ rotary vane vacuum pump The parameter is 6×10-2 Pa, the pump is connected to the motor shaft, high speed, small appearance, compact structure, and convenient fluidity work. It can be used for electric vacuum device manufacturing, vacuum flask manufacturing, vacuum welding, printing, blister, refrigeration Equipment repairs and supporting instruments and meters, etc. Because it has the advantages of small size, light weight, low voice, etc., it is more suitable for use in universities and laboratories.

2XZ Rotary Vane Vacuum Pump--Product features

2XZ rotary vane vacuum pump is equipped with a gas ballast valve, which has the function of prolonging the use time of the vacuum pump oil and preventing the pump oil from mixing with water.

2XZ rotary vane vacuum pump has the advantages of small size, light weight, low noise, easy start-up, installation and maintenance. In addition, there are measures to prevent oil return and measures to contaminate the site by oil seal leakage.
1. The 2XZ rotary vane vacuum pump is the basic equipment to obtain vacuum. It can act alone or as other vacuum pumps, such as the fore pump and pre-pump of the Roots vacuum pump. It is composed of Roots rotary vane unit.
2. The air inlet of the pump is continuously open to the atmosphere for no more than two minutes.
3. The pump is not suitable for pumping gas that is corrosive to metals, chemically reacts to the pump oil, and contains particulate dust, or gas with high oxygen content and explosive gas.
4. The pump can be used as a compression pump or a delivery pump.
5. The working environment of the pump: the temperature is within the range of 5℃-40℃, the relative temperature is not more than 90%, and the air inlet pressure is less than 1333Pa, allowing long-term continuous operation.
6. When installing the power supply, connect the wires in accordance with the regulations on the motor's label, and pay attention to the direction of rotation of the motor to be consistent with the direction of the arrow on the support.
7. The diameter of the pipeline of the continuously pumped container should not be less than the diameter of the inlet of the pump, and the pipeline should be short and have few elbows. At the same time, pay attention to the leakage of the pipeline.
8. Focus on checking the oil level of the vacuum pump before each start. It is advisable to fill the oil to the height of 4/5 of the diameter of the oil standard glass when the pump is stopped.
9. The pump oil is clean SY1634-70 No. 1 vacuum pump oil.
10. The 2XZ rotary vane vacuum pump can be started at one time under the atmosphere or any vacuum degree. If the XZ-1 single-stage pump is difficult to start, it can be started by removing the plug cap of the intake pipe and then put into operation.

2XZ Rotary Vane Vacuum Pump--Product structure

The 2XZ rotary vane vacuum pump is a rotary vane vacuum pump with a capacitive variable direct connection structure. It has a rotor eccentrically installed in the pump cavity and a rotary vane (scraper) in the rotor slot. When the rotor drives the rotary vane to rotate, the rotary vane closely adheres to the inner wall of the pump cavity to separate the inlet and exhaust ports, and the volume of the intake accumulating cavity is periodically expanded and sucked in, while the volume of the exhaust cavity is periodically reduced. The compressed gas pushes open the exhaust valve to exhaust, thereby obtaining a vacuum.
