When we use industrial cooling fans, we sometimes encounter a more common failure, that is, industrial cooling fans are not cooling, so how to deal with such situations? Let us look at this What are the possible causes of the failure?
Industrial cooling fan does not cool and common troubleshooting methods
1, the water level is low, the float valve adjustment error
Solution: It is better to adjust the water level to about 80-100.
2, the drain valve is stuck
Solution: Replace the drain valve.
3. Filter water distributor is blocked
The filter water distributor is more likely to be fouled, and timely cleaning is very important to prevent the occurrence of fouling.
4, the filter is dirty
Long-term use of the air cooler filter will inevitably cause dirt. If it is too dirty, it must be cleaned in time.
5, water pipe fouling
If the water quality is unclear, it is easy to cause such problems. In time, it is best to clean it after the end of each day, which will extend its service life.
6, the pump burned
This is the most serious problem, and it is also a problem that directly leads to non-refrigeration. At this time, it should be replaced in time, and regular inspection should be carried out in normal use, so that the incidence of failure can be reduced.
Common malfunctions
1. The wet curtain part is not wet when the air conditioner is cooling:
The air conditioner water distributor is blocked, the dredging can be cleaned, or there is no installation level, and the level must be padded.
2. The wet curtain is not wet when the air conditioner is cooling (the cooling control display is normal):
Check if the water distributor and distributor water supply pipe are blocked, whether the water pump inlet is blocked, and check whether the pump is working properly.
3. The cooling icon on the controller flashes.
This information indicates that the water level in the chassis is not enough, check whether the inlet pipe valve is closed, the inlet valve is blocked, or whether the water is stopped. If the water level in the chassis is normal and the water shortage is still displayed, the water level probe is faulty.
4, leaking water:
A. Water leakage from the inlet pipe: the metal pipe is damaged or there is no seal.
B. Water leaks from the overflow of the drain valve: At this time, the water level is too high, and the inlet valve float should be lowered.
C. Leakage of the side plate: There is a foreign matter left on the wet curtain, it can be removed, or the machine is not installed.
5. The air conditioner controller does not display:
At this point, check the air conditioner power supply and check if the electrical protection device is operating. If the three live and neutral wires are connected incorrectly when the three cameras are connected, the control panel fuse is blown.
6, three-phase motor type boot machine does not work, the motor emits Weng sound: power supply phase loss, need to check whether the three-phase power supply is normal.
