AI Technical Summary
In existing circulating water supply systems, the high head of the circulating water pump is mainly used for high-position heat exchangers, while low-position coolers do not require such a high head. This results in a large number of manual cooler throttling controls, increasing power consumption.
A multi-pump cascade water supply system is adopted, including variable frequency pumps, pipelines and booster pumps. By combining the use of variable frequency pumps and booster pumps, cascade water supply is achieved, the outlet pressure of the circulating water pump is reduced, the pipeline design is optimized, and power consumption is reduced.
This enabled the high-position cooler to operate normally, while significantly reducing power consumption and improving the operational safety of the circulating water pipeline and the cooler.

[0025] The embodiment of the application provides a multi-water-pump cascade water supply system, which solves the circulating water supply form of the prior art, and the high lift of the circulating water pump is only required by the heat exchanger at a high position in the device. The cooler at a low position does not require such a high lift, and therefore a large number of manual coolers are required to control the flow control of the inlet and outlet valves, and the inlet and outlet valves of the high-position cooler are all opened, so that the problem of high power consumption during normal operation is solved.

The pressurizing pump 23 arranged at the connection between the bottom pipeline 221 and the high-level pipeline 222 is started to transmit the fluid into the inside of the high-level pipeline 222, avoiding the scenario that there is no water available in the high-level pipeline 222 during the peak period of water use. When the direction of the pressurizing pump 23 needs to be adjusted, the fixing seat 31 at the bottom of the pressurizing pump 23 is clamped into the positioning groove 34 at the top of the rotating disc 33, and the fixing bolt 35 is tightened. At this time, the worm 38 is rotated, the worm 38 drives the worm gear 37 to rotate, since the worm gear 37 is fixedly connected with the rotating shaft 36, the rotating shaft 36 drives the rotating disc 33 to rotate together, achieving the purpose of adjusting the direction of the pressurizing pump 23. The device is simple and convenient to operate, improves the production safety, greatly reduces the power consumption of the variable frequency water pump 21, saves the processing cost, and meets the needs of the users.

The pressurizing pump 23 is arranged at the connection between the bottom pipeline 221 and the high-level pipeline 222.
