1. The amount of circulating water is too large. Part of the water pipe (with the water tank) is blocked by the water hole, causing a bias current. In and out of the air is not smooth or short circuited 4. The ventilation is less than 5. The inlet water temperature is too high. Suction and exhaust air short circuit 7. Partial packing of the packing caused a bias current. Outdoor wet bulb temperature is too high
Processing method: 1. Adjust the valve to the appropriate amount of water or replace the capacity matching cooling tower. Clear the blockage 3. Identify the cause and improve 4. See the solution for insufficient ventilation. Check the cause of the chiller. Improve air circulation flow to DC 7. Clear the blockage 8. Reduce the amount of cooling water
1. Fan speed reduction (1) drive belt slack (2) poor bearing lubrication (1) FRP cooling tower adjustment motor position tension or replacement belt (2) refueling or replacement of bearings 2. The fan blade angle is not suitable. Fan blade damage Part of the packing is blocked. Adjust to the appropriate angle 3. Repair or replace 4. Clear plugging water tray (tank) overflow
1. The water tray (tank) water outlet (filter) is blocked. The float valve fails and cannot be automatically closed. The circulating water volume exceeds the rated capacity of the cooling tower. Clear the blockage 2. Repair 3. Reduce the circulating water volume or replace the capacity matching cooling tower water tray (tank) water level is low
1. The float valve opening is too small, resulting in a small amount of water. Insufficient hydration pressure, resulting in a small amount of water. The pipeline system has a leaky place. Excessive water loss during the cooling process. Small water supply pipe diameter is small
1. Open to the appropriate opening 2. Identify the cause, increase the pressure or increase the diameter of the pipe. Identify the leaking area and plug it out. See the solution for excessive water loss during the cooling process. Replacement has obvious floating water phenomenon
1. The circulating water volume is too large or too small. Excessive ventilation 3. There is a bias phenomenon in the filler. The water distribution device speed is too fast. Improper installation of water jacket (flap)
1. Adjust the valve to the appropriate amount of water or replace the capacity matching cooling tower. The FRP cooling tower reduces the fan speed or adjusts the fan blade angle or replaces the fan with a suitable air volume. Identify the cause and make it flow 4. Adjust to the appropriate speed 5. Adjust the cloth (with) water uneven
1. Part of the water outlet hole of the cloth water pipe (with the water tank) is blocked. The circulating water volume is too small. Clear the blockage 2. Increase the amount of circulating water or replace the capacity of the cooling tower with water overflow in the water tank
1. The water outlet hole of the water distribution tank is blocked. Excessive water supply
1. Clear the blockage 2. Adjust to the right amount of water or replace the capacity matching cooling tower with abnormal noise or vibration
1. The fan speed is too high and the ventilation is too large. The bearing is short of oil or damage. The fan blades collide with other components. Some parts of the fastening bolts are loose. The fan blade screw is loose. The belt rubs against the protective cover. The gearbox is short of oil or the gear set is worn out. Friction sleeve (flap) and packing friction
1. Fans that reduce the fan speed or adjust the fan blade angle or replace the appropriate air volume. Refueling or replacing 3. Identify the cause and eliminate 4. Fasten 5. Tightening the belt and tightening the protective cover 6. Add enough oil or replace the gear set. Adjust the water sleeve (flap) or filler dripping too loud
1. The water flow bias of the filler The amount of cooling water is too large. Identify the cause and make it flow 2. Decrease by 3. Add a sound absorbing pad to the water collecting tray. Change to the model of the filler buried in the water tray

Deep Groove Ball Bearings
Deep groove ball bearings The out looks of them are nearly the same,the only different is the size,you may need other models please check the following table for reference.are the most widely used bearing type and are particularly versatile.
They have low friction and are optimized for low noise and low vibration which enables high rotational speeds.
They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.
Deep groove ball bearings are divided into the following series: 6000series, 6100series, 6200series, 6300series, 6400 series, 6700 series, 6800 series,6900 series,16000 series etc.
