There will be some faults in the operation of FRP cooling tower. After the failure, the causes of these faults should be analyzed first, and then corresponding measures can be taken. For example, in the operation of the water temperature can not fall down is sometimes a normal phenomenon, and sometimes the cooling tower is out of fault, which needs to be analyzed according to the specific situation.
1. The water temperature under normal circumstances can not be lowered
In the design of cooling tower, the meteorological parameters used, such as dry, wet bulb temperature, etc. It is selected according to a certain guarantee rate, generally based on meteorological parameters that can exceed 10 or 5 days a year, that is, there should be an average year
If the temperature for 10 or 5 days is higher than the temperature selected in the design, the temperature drop of the water will not meet the design requirements. The purpose of selecting meteorological parameters in this way is mainly to consider economic problems. Because the temperature is determined by years of accumulated statistical meteorological data, if the highest temperature is selected, because the number of days is very short, the cooling tower designed in this way may be very uneconomic. In addition, the daily average temperature is selected in the design, which is the average temperature measured at 2:00, 8:00, 14:00 and 20:00 every day, lower than the highest temperature in a day. This is sometimes short - term water temperature can not fall down the reason, this phenomenon belongs to the normal situation. In this case, if the use of groundwater as supplementary water, because of the low temperature slope of groundwater, can be appropriate to add some groundwater, so that the mixed water temperature to meet the requirements of use.
2. The cooling water temperature of the cooling tower rises
The rise of cooling water loss may be caused by two factors, which should be analyzed and treated in detail. From the point of view of the fan system, the fan does not operate because of power supply and line fault, bearing wear or nano-fracture affects the air volume 'the blade Angle of the fan is wrong, affects the air volume' the fan blade is damaged and the air volume is not enough; Slack belt, insufficient energy transfer: or blocked air duct. Poor air circulation and other reasons may cause the rise of water temperature. The treatment method is to overhaul the power supply and circuit, replace the bearing and shaft, adjust the blade Angle or replace the blade or drive belt. From the circulating water system, the amount of water is too much or insufficient, the water pipe or the water slot is blocked. Make water insufficient, affect water evaporation in the air; Circulating water deflection, will also weaken heat and mass transfer, cooling capacity. The solution to the problem is to adjust the water supply valve, clean the cloth pipe or sink.
