Rotary vane vacuum pump system with double - stage high - speed - speed - straight - structure - rotary vane - vacuum pump. It is eccentric in the pump chamber of the rotor, and rotor slot in the rotating film. Rotor driven rotary vane rotor, rotary vane close to the chamber wall, into the exhaust port separated, and the air inlet area of cavity volume cycle of expansion and inhale, discharge chamber volume is periodically reduced and compressed gas, opened the exhaust valve, so as to obtain a vacuum. Schematic diagram of a single - stage pump. Double is two single series and into.

旋片式真空泵装有气镇阀，具有延长泵油使用时间和防止泵油混水的作用。

Rotary vane vacuum pump with gas ballast valve, can prolong the use time and prevent the oil pump water pump oil.

旋片式真空泵具有体积小，重量轻、噪声低、起动方便等优点。此外，还有防止返油的措施（-8）和无防止油封漏油污染场地的措施。

The rotary vane vacuum pump has the advantages of small size, light weight, low noise and easy starting, etc.. In addition, there are measures to prevent oil return (-8) and no measures to prevent the oil spill contaminated site.

1、旋片式真空泵是获得真空的基本设备，它可单独作用，亦可作为各类高真空系统的前级泵和预抽泵。

1, rotary vane vacuum pump is the basic equipment to obtain the vacuum, it can be a separate role, but also as a variety of high vacuum system of the first pump and pre pump.

2、泵进气口连续敞通大气运转，不得超过三分钟。

2, the pump inlet continuous open air operation, not more than three minutes.

3、泵不适用于抽除对金属有腐蚀性的，对泵油起化学反应的、含有颗粒尘埃的气体，以体含氧过高的，有爆炸性的气体。

3, the pump does not apply to the pumping of metals corrosive, the chemical reaction of the pump oil, containing particulate dust gas, oxygen is too high, explosive gases.

4、泵有得作压缩泵或输送泵用。

4, the pump had to pump for compression or pump.

5、泵的工作环境：温度5℃-40℃范围内，相对温度不大于90%，进气口压强小于1333Pa的条件下允许长期连续运转。

5, the working environment of the pump: the temperature is within the range of 5, the relative temperature is no more than 90%, the inlet pressure is less than 1333Pa, and the long-term continuous operation is allowed..

6、装接电源时，按电机标牌的规定接线，应注意电机旋转方向与支座上的箭头方向一致。

6, when the power supply, according to the motor signs wiring, should pay attention to the direction of the motor rotation and the bearing on the arrow direction.

7、连续被抽容器的管道，其直径应不小于泵的进气口直径，且管道应短和弯头少，同时注意管道的泄漏。

7, continuous pumping vessel pipe, its diameter should not less than the inlet diameter of the pump, and the pipeline should be short and elbow, while the pipeline leakage.

8、每次起动前着重查看油位，以停泵时注油至油标玻璃直径的4/5高度为宜。

8, every time before starting to focus on the view level, to stop the pump when the oil to the oil standard glass diameter 4/5 height is appropriate.

9、具泵油采用清洁的SY1634-70 1号真空泵油。

9, with the use of pump oil clean SY1634-70 1 vacuum pump oil.

10、旋片式真空泵可在通大气或任何真空度下一次起动。XZ-1单级型泵如果起动困难，可拨掉进气管塞帽起动，随后投入运转。

10, rotary vane vacuum pump can start in the atmosphere or any vacuum degree. XZ-1 single - stage pump can start up the intake pipe plug cap if starting difficult, then put into operation..
