Installation of fans, whether it is axial fan, jet fan, explosion-proof fan, subway fan or tunnel fan, fan connections are required to be carefully installed, to control the fan number and performance parameters to install, to ensure that the installation is correct. Xiaobian below to explain to you under the group Kai fan installation method, there may be a need to look at!

1, the fan shell and gas pipeline connection, the weight of the gas pipe should not be added to the fan on the shell.

2, fan installed in series, the fan number of the performance parameters should be consistent, and to ensure that the installation location to maintain the fan diameter of more than 5 times the distance. When the fan is installed in parallel, the fan number and performance parameters must be kept in parallel.

3, the installation of wind turbine control cabinet, must be qualified professional certified electrician. First connect the power cord to the junction box of the fan housing. The power cord must be flexible enough to block the normal movement of the fan. After connecting the fan end, then connect the cabinet side.

Single-speed fan wiring: the motor power ≤ 3KW for the Y wiring, the motor power> 3KW △ wiring.

Two-speed fan wiring: the company's two-speed fan with two-speed motor stator winding △ / YY (or Y / YY).

5, fan installation wiring, must be installed according to the motor connection grounding protection line. When the wiring is completed, the cable entry should be plugged to prevent dust and water vapor from entering the motor junction box. Tighten all bolts to prevent contact heat resistance is too high and cause the heat of the wire to increase.
