When starting the FRP cooling tower, the fan should be started first, and then white water should be pumped. When the equipment stops, the pump should be stopped first, and then the fan should be turned off. This can reduce the motor from carrying heavy current and try to take care of the motor. When checking and repairing the fan, special personnel should be responsible for operating the power switch to prevent personal accidents. The fan motor does not take a long time, so we should take good care of it.
If it is found that the speed of the distributor is not fast, it should be repaired and debugged as soon as possible. Under normal circumstances, it should be controlled at 9-15rpm and the office pressure is 1.5kg. If you need to check the nozzle regularly, please check whether the nozzle is blocked.
This facility should be managed by a special staff member. It must have a management system, operating procedures, regular protection, regular dosing, cleaning to avoid blockage and affect the cooling effect, replace or repair gears, replace lubricating oil, check whether the float valve assembly is installed and operated normally, check all screws and screw covers, fasten tightly, rely on the cooling tower, and cannot relax. The watermark position is calibrated: the basin and water pipe at the bottom of the storage tower are filled with water to the watermark of operation, that is, the installation surface of the inlet bracket on the chassis. After the operation is completed, the floating ball valve combination will clamp the watermark position in the drawing position.
Maintenance of glass fiber reinforced plastic cooling tower is particularly important in the use of glass fiber reinforced plastic. In order to make the cooling efficiency of the chiller high and the operation of the whole equipment stable during the use of glass fiber reinforced plastic cooling tower, the following maintenance work should be done regularly in order to make the glass fiber reinforced plastic cooling tower be used normally for as long as possible.
Glass fiber reinforced plastic cooling tower is used with water-cooled chillers. For cooling towers using belt deceleration devices, stop the machine every two weeks to check the tightness of the belt. If not, adjust it. If several belts have different tightness, replace them completely. If the cooling tower does not run for a long time, remove the belt and save it.
The glass fiber reinforced plastic cooling tower mainly uses gear reduction device when it is in operation, so stop the machine every month to check the oil level in the gear box, and add it when the oil is not enough. in addition, the color and viscosity of the oil should be checked every six months of operation of the cooling tower, and if it fails to meet the requirements, it should be replaced. when the cooling tower has been used for 5000h, regardless of the oil quality, the gear box should be cleaned and lubricating oil should be replaced, the cooling tower can provide continuous cooling water for the chiller.
The common cooling tower equipment in the glass fiber reinforced plastic cooling tower occupies a relatively small space range, but it can complete the same workload in a smaller space range, so that the same cooling can be played.
In the process of maintenance of glass fiber reinforced plastic cooling tower, after the installation of its equipment, it should carefully remove the debris and dirt treated by the pipeline, water collector, the surface of the filler and the collecting pool, so that it can effectively avoid blockage.
Before the glass fiber reinforced plastic cooling tower is used, it should be put into trial operation first. During the operation of the cooling tower, it should effectively check whether the fan and tower body are installed smoothly, whether the water distributor is running normally, whether the water distribution nozzle is evenly discharged, and whether the moisture-proof measures of the motor are tight.
During the use of FRP cooling towers, you should always observe the operation of the fan. The current, voltage, fan vibration, noise, gear oil level, whether there is oil leakage or whether the belt drive is loose, whether there is slippage, whether the water distribution is normal, etc.
The belt drive bearing seat of the glass fiber reinforced plastic cooling tower needs to be filled with lubricating grease during operation. It needs to be filled with its oil gun once a month at ordinary times. Every year of continuous operation, it is completely disassembled and replaced. Attention should always be paid to the fastening of connecting parts and bolts.
Glass fiber reinforced plastic cooling tower water turbidity is not more than 10 mg/L, operation, should be based on the water quality, consider regular sewage or increase the water quality stability treatment, filler material using modified temperature resistant rigid polyvinyl chloride (PVC), or high temperature resistant polypropylene (PP).
