Please tell me how to maintain the fan belt in the cooling tower? ! It keeps beating and slips and wears out quickly! (Supplementary picture)

This post was last written by blade_wzy edited on 2019-7-19 14:21 There are two cooling towers in the device. The fans are driven by belts, and the entire motor transmission components are in the tower. The current problem is that the belts start to beat within a short period of time when the two machines are running. The current drops and the fluctuations become larger. The only option is to increase the belt tension. ； After a while, the belt started to beat again, so I continued to tighten it. ； After several consecutive times, the belt wear exceeds the standard. After all, the tension continues to increase, and the belt is too thin and cannot be used anymore, so the belt must be replaced with a new one. Tensioning needs to be done about once a week, and the belt will be scrapped after a month or two. It is simply a vicious cycle. Moreover, the on-site working environment is harsh. The cooling tower is already very hot. Working in it on hot days is like a sauna. Now the frequency of work is so high that life is worse than death. Safety considerations such as restricted space are really troublesome. Analyzing the reason, I personally feel that it is the influence of water vapor in the tower on the belt that makes it easy to slip. When the fan is running, I open the door and find water droplets flying upward. ； As for the belt, only the motor pulley has a cover, and the rest are basically open-air. ； It is more obvious on rainy days, and the direct current drops significantly during heavy rain. This structure is probably the advantage of a small footprint. After all, our factory is very large. A large number of other cooling tower fans are in the form of long-axis couplings and do not use belts. I don’t know if this type of fan is used in your installation. How is the maintenance of the belt? Are there any good ways to improve it?
How does the belt jump? Jump up and down or side to side? Is it leveled?
It is best to send a video with this issue, take a panoramic view, and then discuss the internal settings. There are a lot of transmission equipment now. Is it possible to consider technical modification? Nowadays, most of the small cooling towers use fans driven by motors and speed increasers. Can we learn from this?
Suggest an improvement proposal and replace it with a coupling as soon as possible.
It just jumps up and down, the belt feels loose, the leveling has been found, and the pulley grooves have been checked, no problem.
Isn't it because there is no room on site, so I can only choose such a scam.
Based on the edge line of the pulley groove, pull the wire to check whether the relative position of the pulley is out of tolerance.； Check whether the pulley is too tight or loose during installation. In addition, the hot and humid environment is indeed not conducive to the long-term operation of the belt. If the belt installation meets the technical requirements, additional maintenance and replacement will be required.
Thanks to those above. But most people's opinion is to change it to a coupling, which is really impossible to achieve based on the photos. It's really strange. I checked online that this kind of fan is also useful in other places. Don't they need frequent maintenance? !

It has only been 6 days since the last tensioning belt was tightened and it needs to be tightened again. Inside the cooling tower on a high-temperature day of 36 degrees. . . Oh my God! ! ! :Q:Q:Q:'(:'(:'(
