气环式真空泵之应用技术
A.送风-入口应加装大型过滤器
1. 出气口之总截面积应大于气环式真空泵出口截面之1/2。
2. 如用于水中送气，其水深应在型录上所标示使用静压值之80%o
3. 在加压送气之使用时，出口温度因空气磨擦的关系会大于常温10P以上属于正常，故应使用铁管1M以上。

A. Blowing The installment of a large-sized filter at the end of inlet is recommended.
1. The total sections of outlets should be half more than the outlet section of the blower.
2. If use as an air pump under water, the water level should between 80% of the maximum which show on the catalogue.
3. At least one meter long iron tube should be applied to the blower when it used as deliver air under pressurization, due to the exhaust temperature will be 10°C higher than the normal atmospheric temperature by the compression of air.
B. 吸风-出口可装消音器。
1 .吸入口之总截面积应大于气环式真空泵入口截面积之1/2。
2.如用于全闭吸着时或管路特长需长时间工作请先咨询本公司营业部。

［安装］
(1)安装场所一周围温度与湿度，应符合以下条件：
•三相-10 ~ 40C 单相-5 ~ 40P
•选择通风良好，尘埃及湿气少之场所。开放型马达防尘及防潮较弱，尤其须注意。
•设于露天者，请使用雨罩。
INSTALLATIONS
(1) Install places— The environment should follow the conditions below
•The ambient temperature for three-phase blower is40°C ~ 40°C, and for single-phase blower is-5°C~ 40°C.
•Good ventilation with less dustａnd humidity. Kindly pay extra attention to ODP(Open Drip Proof) motor for its weak at dust-proof and damp-proof. •If the blower is used outside, please set up the canopy.
