Description

Technical Field

[0001] The utility model relates to the technical field of self-priming booster pumps, in particular to an antifreeze vortex type self-priming booster pump. Background Art

[0002] As a device for conveying liquid media, different water pumps have different functions, performances, and uses. In old residential areas, places with many households, frequent water use, or places with scarce water resources, water pumps that are suitable for the location and have superior performance and multiple functions integrated into one are the most important.

[0003] The vortex self-priming booster pump inherits the structure of the traditional vortex pump. First, the booster pump is filled with liquid, and then the vortex pump is started. The impeller rotates rapidly, and the blades of the impeller drive the liquid to rotate. When the liquid rotates, it flows to the outer edge of the impeller by inertia. At the same time, the impeller sucks liquid from the suction chamber. In this process, the liquid in the impeller flows around the blades, and the liquid generates lift on the blades during the flow movement. Conversely, the force exerted by the blades on the liquid is equal to the lift in magnitude and opposite in direction. This force does act on the liquid, allowing the liquid to gain energy and flow out of the impeller.

[0004] In northern regions or in winter, people wrap insulation materials on water pipes and build an insulated working box outside the water pump. However, the insulation effect is relatively small. If there is no heat source when the temperature is low, the water pump will still freeze. Under normal circumstances, when the temperature is below zero, if the water pump works frequently, the heat generated by the water pump motor can radiate to the surrounding area to increase the temperature in the insulation box, and the water pump will not be frozen; the water in the water pump will also affect the pipe from being frozen.

[0005] However, if the water pump is not working for a long time, it will often freeze. Starting the water pump when it is frozen will cause damage to the water pump. In order to solve the above technical problems, the pump body needs to be improved. Summary of the invention

[0006] The technical problem to be solved by the utility model is to provide an antifreeze vortex self-priming booster pump, which has the characteristics of automatically adapting to the temperature of the working environment and preventing freezing and cracking.

[0007] The utility model solves the technical problem by adopting the following technical scheme: providing a micro pump syringe, comprising a pump motor, a pump body and an impeller, wherein the pump motor is provided with a pump body mounted on one end of a main shaft, an impeller is mounted in the lower part of the pump body, the main shaft of the pump motor is inserted into the pump body and connected with the impeller, an air storage tank docked with the upper part of the pump body is mounted on the upper rear part of the pump motor, a temperature and pressure sensor docked with the pump body is mounted on the front side of the air storage tank, a water inlet and outlet are both arranged on the upper rear side of the pump body and the upper front end of the pump body, the air storage tank comprises an air storage tank sealing cover, a water storage bag and an air tank body, a water storage bag is mounted on one side of the air storage tank sealing cover, a air tank body wrapping the water storage bag is mounted on the side of the air storage tank sealing cover where the water storage bag is mounted, a connecting shaft sleeve is mounted between the air storage tank sealing cover and the pump body, and the connecting shaft sleeve communicates the water storage bag with the inner cavity of the pump body.

[0008] In the technical solution, a pump motor is provided to drive the rotation of the impeller, and the rotation of the impeller is used to transport liquid.

In the technical solution, a water storage bag is provided to store excess liquid. When the pressure inside the pump body is greater than the pressure of the compressed nitrogen in the air tank body, the liquid inside the pump body will enter the water storage bag, so that the pressure in the pump body is reduced.

A temperature and pressure sensor is set into the pump body to detect the temperature and pressure in the pump body. When the temperature is too low, the pump motor rotates. The heat generated by the pump motor during operation can radiate to the surroundings, thereby increasing the temperature in the heat-insulating environment and the water pump will not be frozen.

[0010] As a supplement to the present technical solution, an impeller mounting hole is provided on one side of the pump body, and an impeller cover for sealing the impeller mounting hole is installed on the impeller mounting hole. In the present technical solution, the impeller cover is used to seal the impeller mounting hole.

[0011] As a supplement to the present technical solution, a control panel is installed on the front side of the pump motor. By setting the control panel, the control panel is used to control the start and stop of the pump motor in the present technical solution.
