Large industrial electric fans and introduce some of the considerations

Large electric industrial fans, the maximum diameter of up to 7.2 meters a huge fan! Streamlined

aerodynamic principles and advanced blade manufacturing process, only use 1.5KW can drive a lot

of air, resulting in a large area of ​​natural breezes system, serve the dual function of

ventilation and cooling. Compared to traditional HVAC and small, high-speed fans, it has

unparalleled application advantages, called the large space ventilation and cooling of the

perfect solution. weiyu 5-blade structure, over an area of ​​1,200 square meters. ʱ??

electric industrial fan during use should be simple daily maintenance and inspection to ensure that the

industrial life of the fan.
1 industrial electric fans belong to the high-speed moving parts, must be checked before starting the

standard lubricants, the oil level should be in the red.
2 industrial electric fans start-up mode is the key to ensure safe operation. Special Note: The start

and stop shall under no-load conditions. Start should be in accordance with the following

requirements:
A, hand dish suction fan cable wiring;
B, and vent valve open. When you first start, aeration tube valve should open;
C, industrial electric fans start to start with a specially designed box (from the lotus or soft start);
D, industrial electric fans should be in the rated speed, slowly close the vent valve, press the

aeration requires aeration valve is adjusted to the required position until all the vent valve

closed.
E, after industrial electric fans running, bearing parts temperature should exceed the instructions

provided, the general should ≤50 ~ 60 ℃. Do not follow the above way to start, may cause

suction fan overload, burn suction fan. Shutting down the suction fan should reverse procedure,

which is to slowly open the vent valve, then shut down the suction fan. Is not required, the

sudden shutdown may cause water intrusion into the suction fan, causing damage to the suction

fan.
3 The wind industry fan is installed in the air inlet duct silencer and muffler; if the water

industry after fan cooling water should be pre-open, shut down the cooling water, cooling to

keep running well under the regulation.
