On the compatibility between the motor of the water pump and the pump itself
Thread Content
The cooling water tower circulation pump has a rated power of 7.5 kW, with a flow rate of approximately 150 cubic meters per hour； Through the coupling, the motor used is a 15kw motor. The pump and the water tank are located on the 1st floor, while the cooling tower is installed on the roof. The water pump draws circulating water from the tank on the 1st floor, sends it to the cooling tower on the roof, and after it has been cooled by the tower, the water returns to the tank on the 1st floor. Since there is no water stored in the cooling tower, will the actual flow rate be higher than the rated value? Is the pressure still higher than the rated value? Or is both the flow rate and pressure high? In actual use, this water tower causes quite severe splashing of water; water splashes out from the intake openings, and the water is also drawn up from the top of the tower by the cooling tower fans and scattered everywhere. How can this be resolved? Seeking expert advice! !
1. Regarding the younger brother’s question, it is difficult to provide a satisfactory answer since all the conditions are not specified. 2. Based on the given conditions, assuming that the pump is 15 meters above the roof cooling tower and the flow rate is 150, the motor should be sufficient. 3. The flow rate depends on the pump’s performance curve and the characteristics of the piping, but data for both is unavailable. 4. Since the rated pressure is not provided, it is impossible to make any comparisons. 5. Water splashing from the water tower is related to the fan, not to the water pump. As for the mist dispersion, measures such as installing baffles with a proper design and enhancing the capacity of the exhaust fans can be employed
