Description

Technical Field

[0001] The present application relates to the technical field of return water pumps, and in particular to a return water pump for regional cooling. Background Art

[0002] A return pump, also known as a circulation pump, is mainly used to accelerate the circulation speed of fluid in the system. It sucks fluid in the return pipe of the system and discharges it after pressurization, thereby improving the flow efficiency of the fluid, increasing the heat exchange rate, or maintaining a constant water flow in the heating system. The working principle of the return pump is usually based on centrifugal force, which increases the energy of the fluid through the rotation of the impeller.

[0003] However, the return pumps sold on the market are all single-turbine pumps. In the process of accelerating the return of regional water sources, the single-turbine pump cannot keep up with the supply speed due to the excessive flow rate of the accelerated water flow. After the pipeline is diverted, the water pressure inside the pipeline is low, making it difficult to achieve regional return. If large-area return is to be achieved, the only way is to increase the number of pumps. This method will lead to problems such as higher installation costs for the return pump and larger floor space.

[0004] Therefore, it is necessary to provide a return water pump for district cooling to solve the above problems.
