2XZ rotary vane vacuum pump has the advantages of small size, light weight and low operating sound. The laboratory equipment that can be used with it is vacuum drying box, freeze dryer, short-distance distillation equipment and other experimental equipment.
2XZ rotary vane vacuum pump is a two-stage direct-connected structure. Its working performance consists of two parts: high-pressure stage and low-pressure stage. Its suction port is connected to vacuum equipment, and a large amount of gas in the container is sucked in and discharged during operation. When the equipment obtains a 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 vacuum equipment. 2XZ rotary vane vacuum pump technology The parameter is 6 × 10-2 Pa, the pump and the motor are connected to the shaft, high speed, small size, compact structure, convenient fluidity work, can be used for electric vacuum device manufacturing, vacuum flask manufacturing, vacuum welding, printing, plastic suction, refrigeration Equipment repair and instrumentation. Because it has the advantages of small size, light weight, and low operating sound, it is more suitable for laboratory use. 2XZ rotary vane vacuum pumps can be used with laboratory equipment such as vacuum drying ovens, freeze dryers, short-path distillation equipment and other experimental equipment.
1, 2XZ rotary vane vacuum pump is the basic equipment to obtain vacuum, it can function alone, can also be used as the fore pump and pre-pump of various high vacuum systems to form Roots rotary vane vacuum unit.
2. The air inlet of 2XZ rotary vane vacuum pump is continuously open to the atmosphere, and it should not exceed three minutes.
3. The pump is not suitable for the removal of gases that are corrosive to metals and chemically react with the pump oil and contain particulate dust. Gases that contain too much oxygen and are explosive.
4. The pump may be used as a compression pump or a delivery pump.
5. Working environment of 2XZ rotary vane vacuum pump: in the temperature range of 5 ℃ -40 ℃, the relative temperature is not more than 90%, and the inlet pressure is less than 1333Pa to allow long-term continuous operation.
6. When connecting the power supply, connect the wires according to the specifications on the motor label. Pay attention that the direction of rotation of the motor is the same as the direction of the arrow on the support.
7. The diameter of the pipeline to be continuously pumped should be not less than the diameter of the air inlet of the pump, and the pipeline should be short and the number of elbows should be small. At the same time, pay attention to the leakage of the pipeline.
8. Focus on checking the oil level before each start. It is advisable to fill the oil to a height of 4/5 of the diameter of the oil gauge glass when the pump is stopped.
9. For pump oil, use clean No. 1 or No. 100 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, you can remove the intake pipe plug cap to start and then put it into operation.
