11). Adjust the tightness of the belt of the fan unit (Be Suit For 25KW~40KW)
The rotation of the fan is achieved by the transmission of the belt. The velocity and stability of the fan is
associated with the tightness of the belt and the tightness should be adjusted after a period of time. For a
new belt, the tightness should be adjusted for at least twice within 24 hours.
After one week running, the tightness of the belt should be adjusted again, we should routinely check it
every 1-2 months; also ensure the test results complying with Table 2.
The adjustment of the tightness of the belt is shown in Fig. 25. Loosen screws fixing motor on the base,
move motor along the direction of arrow as shown in the picture, then fix the screw again.
The tightness level of belt is tested by tensiometer as shown in Fig. 26, when reaches the deviation △
length(Deviation=The total length beit/64) ,read the value on the meter, the value should be in the
category specified in Table 2.
