In the long running process of closed cooling tower, the machines and equipment will suffer from different degrees of corrosion and loss, and many parts in the cooling tower may also suffer from common faults of different degrees. The common failure rate of circulating pump of cooling tower is very low, but the circulating pump is related to the whole cooling cycle, so as long as the common failure occurs, it is necessary to implement treatment in a short time. The most common fault of the circulating pump is that there is no water, and the circulating pump will also operate, but the closed cooling tower can not carry out spray circulation. For this common failure, the technical professional cooling tower manufacturer, Guangdong Teling Energy-saving Air Conditioning Equipment Co., Ltd. summarized the following reasons for your reference.
1, circulation pump inlet and outlet reverse connection. The situation at the time of first installation operation is relatively common, circulating pump with water and the water two interfaces, if use undeserved will occur in and out of the nozzle, in these circumstances, circulating pump in case of an electricity will continue to normal operation, just reverse, and circulating pump is not for water, if you meet the problem is, we will be circulating pump reshipment at once.
2. The power supply burden of circulating pump is insufficient. The circulating pump voltage is not enough, it will cause the circulating pump speed ratio is weak, the pumping pressure can not be supplied, of course, it can not carry out the water. If it is suspected that the voltage is not enough, we can run the voltmeter to carry out detection. In order to confirm that the voltage is unstable or the voltage is not enough, we should implement the adjustment of the circuit as soon as possible.
3, there is air in the circulating pump, can not reach the vacuum. When running the circulating pump, before the first operation, there is no clean discharge of the water pipe or the air in the pump body, which will also cause the circulating pump to not water. Therefore, it is necessary to fill with water before operation to ensure that water can overflow from the vent hole, and it is also necessary to run the pump shaft to empty the air. If there is a small amount of air in the circulating pump body, it is not able to carry out the water.
4. The head of the pump is too large and the power is too small. If the piping design of closed cooling tower is relatively long, and has a camber, circulating pump can build vacuum is limited, if the water is relatively long, circulating pump of vacuum degree not to, not water circulating pump will happen, it may cause for the burden of circulating pump is not enough, for this problem we should replace the head of the burden of higher, stronger the circulation pump operation.
5, circulation pump embrittlement. Circulating pump running for a long time may cause circulating pump wear, belt, line coil, impeller, such as the original embrittlement, will cause the circulating pump work, causes the circulation pump speed ratio and transmission affected, speed than the lower, belt skid, impeller state such as offset, these situations often happens at the end of the circulation pump is running, if the overall component embrittlement is serious, A new circulating pump must be replaced.
The circulating pump of the closed cooling tower must be properly maintained during the operation process, which can ensure the power and working efficiency of the circulating pump and increase the service life of the circulating pump. The circulating pump of cooling tower has spray circulating pump and water replenishing circulating pump. Water replenishment is designed in the auxiliary machine of the cooling tower to supplement the internal circulation of pure water, because the internal circulation of water through a lot of coil U-bend, and the head is particularly long, the working pressure of the circulating pump is very strong, so it is necessary to carry out regular maintenance!
