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.

•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.

G. Parallel connection
1. Air volume= machine A+machine B 2. pressure= machine A or machine B
H. 气环式真空泵出口由於压力与空气摩擦生热,所以出口应先接用长1M以上铁管
H. Blower and air friction, produce heat due to pressure, so the outlet should be connected with iron pipe long more than 1 meters before. 京1.以上仅供设计上之参考,如有出入以实际所需为准。2.进一步资料，请参阅型录及气环式真空泵使用说明书。3.参考数据：安全系数5.2~1.5

2. For more information, please see type documents and blower instructions. Thanks!
3. Reference points:the safety factor is about one point two to one point five.
bhb型---其压力与电流成正比，静压愈高则电流愈高，为了减少故障及节省电力，请尽可能加大进出风口之截面积，或使用风量调节阀。
