Pressure-regulating centripetal force multi-screw supercharged motor pump

Abstract

The invention relates to a pressure-regulating centripetal force multi-screw supercharged motor pump. A motor stator is fixed on the inner wall of a motor shell. A motor pump connecting step is arranged at the port position. The motor shell and a motor pump volute shell are connected into a whole through a motor pump connecting bolt. A supercharger liquid flow compression chamber wall is arrangedon the motor pump volute shell. A supercharger liquid outlet flange and fluid circulation supercharging passage opening pressure-regulating nuts are arranged on a supercharger shell. A fluid circulation supercharging passage opening is formed in the supercharger liquid outlet flange. The fluid circulation supercharging passage opening is communicated with a fluid supercharging passage. Fluid circulation supercharging passage opening pressure-regulating screws are arranged at the upper end of a supercharger liquid flow pressure diffusion chamber wall. The amount of inlet liquid and the amount of pressure of liquid at a liquid outlet of the fluid circulation supercharging passage opening of a supercharger are regulated through the fluid circulation supercharging passage opening pressure-regulating screws. The pressure-regulating centripetal force multi-screw supercharged motor pump has novel design and excellent power saving and supercharging effects and is an updated product of a current fluid machine.

Description

technical field [0001] The invention relates to the technical fields of fluid mechanics and motors, in particular to a pressure regulating type centripetal force multi-screw booster motor pump. Background technique [0002] The existing urban tap water supply system, the closed constant pressure circulation system of urban central heating, the cold and hot water circulation system of central air conditioning, the cooling water circulation system, and the circulation system of secondary heat exchange of domestic hot water are all inseparable from circulation pumps. supercharged. The traditional circulating booster pump has a complex structure, large volume, high energy consumption, and time-consuming and laborious installation. In order to change the current situation of circulating pump boosting in the circulating system, the patent CN2866926Y discloses a shock wave booster, which works well with the booster pump.

The traditional circulating booster pump has a complex structure, large volume, high energy consumption, and time-consuming and laborious installation. In order to change the current situation of circulating pump boosting in the circulating system, the patent CN2866926Y discloses a shock wave booster, which works well with the booster pump. However, due to the large volume of the shock wave supercharger, installation and debugging are very troublesome, and it cannot completely solve the system supercharging problem of the circulating pump.
