2XZ direct drive rotary vane vacuum pump

Products

一、Overview of 2XZ rotary vane vacuum pump:

Rotary vane vacuum pump 2 xz type of two-stage structure, its working performance levels by high pressure and low pressure of the second part, its suction connected to the vacuum equipment, when running the gas in the container to a large number of suction and discharge, when the equipment for vacuum, high pressure stage exhaust valve closed, high pressure gas will be transferred to the second level entrance, and the secondary suction and discharge vacuum equipment can obtain a certain vacuum, rotary vane vacuum pump 2 xz type of technical parameters for 6 x 10-2 Pa, pump and motor shaft, high speed, small appearance, compact structure, liquidity work is convenient, can be used for electric vacuum device manufacturing, vacuum flask, vacuum welding, printing, blister, refrigeration equipment repair, and form a complete set of instruments and meters, etc. Because it has the advantages of small volume, light weight and low operating sound, it is more suitable for use in the laboratory.

二、Working principle of 2XZ rotary vane vacuum pump:

2XZ rotary vane vacuum pump is a two-stage high speed direct-coupled structure rotary vane vacuum pump. It has an eccentrically loaded rotor inside the pump chamber, and a rotor slot inside the rotor. Turn rotor driven rotary vane, rotary vane, close to the cavity wall separating inlet and outlet, and make the air intake periodically to expand product volume and suction, exhaust chamber volume is compressed gas periodically to narrow, pushed open the exhaust valve exhaust, vacuum is achieved. FIG. 1 schematic diagram of working principle of 2XZ rotary vane vacuum pump. Two levels are two single-stage series.

三、Features of the 2XZ rotary vane vacuum pump:

The 2XZ rotary vane vacuum pump has the advantages of small volume, light weight, low noise and easy to start. In addition, there are measures to prevent the return of oil (2xz-8) and the measures to prevent the oil spill from polluting the site.

1. The 2XZ rotary vane vacuum pump is a basic equipment for obtaining vacuum. It can be used alone. It can also be used as a pre-stage pump and a pre-pumped pump of various high vacuum systems to form a roz spiral vacuum unit.

2. 2. 2XZ rotary vane vacuum pump enters the air port continuously open air operation, no more than three minutes.

3. The pump shall not be used for the removal of corrosive to the metal, and the gas containing particle dust in the pump oil, which is high in oxygen, and has an explosive gas.

4. The pump has to be used as a compression pump or pump.

5, rotary vane vacuum pump 2 xz type of working environment: temperature 5 ℃ to 40 ℃, relative humidity is not greater than 90%, the inlet pressure under the condition of less than 1333 pa allows continuous operation for a long time.

6. When installing the power supply, according to the regulation of the motor sign, note that the rotation direction of the motor is the same as that of the arrow on the support.

7. The pipe with continuous pumping vessel should be no less than the inlet diameter of the pump, and the pipe should be short and elbow less, while paying attention to the leakage of the pipe.

8. Check the oil level before starting each start, and it is advisable to pump oil to 4/5 of the diameter of the oil gauge glass when stopping the pump.

9. Pump oil with a clean 1 or 100 vacuum pump oil.

10. 2XZ rotary vane vacuum pump can be started in the air or any vacuum. XZ-1 single - stage pump if the starting difficulty, can dial out the intake pipe plug - cap starting, then put into operation.
