［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.

1 .所需风速约50m/s（米渺）~100m/s（米渺）以上
2.静压请参考选型表
D. Air knife > Conveying、Spray combustion Gas/air=l/24, 100 calories heat need air about 2 m³/min 1 .wind speed need above between 50m/s~100m/s 2.on static pressure please refer to selection diagrams

I— 1.吸风口总面积X50%~80%=气环式真空泵入口面积
E.吸著， 吸风机入口面积X30/s~50m/s=风量(视漏气多少而定)
一2.静压约300mmAq~3000mmAq(视被吸物厚度而定)
E. Suck
a) the total area of suck tuyere X 50%?80%=the inlet area ofblower
the inlet area of suck tuyere X 3 0m/s~50m/s= air volume(depending on the leak to circumstances )
b) static pressure about 300mmAq~30000mmAq (depending on the thickness of the sucked objects)
F. 串联之应用一压力增加(但禁止不同功率串联)
1 .压力=(A机+B机)X90% 2.风量=入机
F. Series connection— pressure increase (But prohibit different horsepower series)
1 .pressure=(machine A+machine B) )X 90% 2. air volume= machine A
G. 并联之应用一风量增加
1.风量=A^n.+B机 2.压力=A机或B机
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
1 .Above are for design reference only. If there is discrepancy subject to actual situation.
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。
