[0003] The utility model with the existing publication number CN215927770U provides a relay pump for high-temperature water return pressurization of regional heating, including a drive motor, a booster pump, a drive assembly, a booster assembly... This device drives the eccentric wheel to rotate through the rotation of the first connecting shaft, so that the toggle plate will rotate along the inner wall of the cylindrical cavity under the action of the compression spring, so that the water flow is discharged from the water outlet pipe after pressurization, which greatly improves the boosting effect and efficiency.

[0004] However, the booster pump will generate a lot of heat after long-term use, and the booster pump is in a relatively high temperature working environment, which makes it difficult to quickly dissipate the generated heat, thereby reducing the working efficiency and service life of the booster pump.

[0005] In response to the above problems, we propose a relay pump for medium-temperature and medium-pressure reflux boosting in district heating. Utility Model Content
