The method of using oil-free vacuum pump correctly

（1）無灰塵及臟物的清潔場所。

(1) clean place without dust and dirt.

（2（應具有充分良好的通風條件及低于40℃的環境溫度。

(2) adequate ventilation condition and environmental temperature below 40 degrees centigrade.

（3）不直接暴露在陽光里。

3) not directly exposed to the sun.

（4）無讓水、油等液體降落到泵上。

(4) no water, oil and other liquids fell to the pump.

（5）泵必須安裝在平坦的平面上。

(5) the pump must be installed on a flat plane.

（6）有足夠的周圍空間能便于泵的檢查，維護和裝拆。

(6) sufficient space to facilitate inspection, maintenance and disassembly of pumps.

（7）必須確保泵不因基礎不牢固而引起震動。

(7) must ensure that the pump does not cause vibration due to the foundation is not strong.

(8)接電線時，應注意電機銘牌上的規定接線要求。三相電泵要注意電機旋轉方向應與泵上的標示箭頭方向一致。

(8) pay attention to the specified wiring requirements on the motor nameplate when wiring. Three phase electric pump should pay attention to the direction of motor rotation should be consistent with the direction of the arrow on the pump arrow.

(9)最好將泵放在類似混凝土堅硬的地基上安裝，如果沒有條件，也可將泵牢固地安裝在鋼制或木制的機架上。

(9) it is better to install the pump on a rigid foundation similar to the concrete. If there is no condition, the pump can be firmly mounted on the steel or wooden frame.

（10）與泵連接管道不宜過長和小于泵進口徑，影響抽速，同是注意檢查真空連接管道有否漏氣。

(10) the pipe connecting with the pump should not be too long and smaller than the diameter of the pump, affecting the pumping speed, and the same attention is paid to check whether the vacuum connection pipeline leaks.
