Description

Technical Field

[0001] This utility model relates to the field of water pump technology, specifically to a self-cooling water pump for circulating water channels. Background Technology

[0002] Water pumps, as fluid transport devices, are widely used in industry, agriculture, and daily life. However, during long-term operation, traditional water pumps are prone to overheating due to the difficulty in effectively dissipating the heat generated by components such as the motor or spindle, which in turn affects the pump's service life and operational stability. The heat dissipation problem is particularly prominent in high-temperature or continuous operation environments.

[0003] Currently, although there are some water pumps with heat dissipation functions on the market, most of these water pumps use external heat dissipation devices or simple heat dissipation structures, which have limited heat dissipation effects and increase the complexity and cost of the equipment.

[0004] Therefore, a self-cooling water pump for circulating water channels has become an urgent problem to be solved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a circulating water channel self-cooling water pump. By setting up a circulating cooling water channel inside the circulating cooling chamber, the water flow is used to dissipate heat from the main shaft and other components, thereby realizing the self-cooling function of the water pump and improving the operational stability and service life of the water pump.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a circulating water channel self-cooling water pump, including a main shaft, a circulating cooling chamber, and a pump chamber. The main shaft is disposed inside the circulating cooling chamber and its power output end extends into the pump chamber; one side of the pump chamber is detachably connected to the circulating cooling chamber; the circulating cooling chamber is provided with a circulating cooling water channel, which is connected to the pump chamber.

[0008] Furthermore, the circulating cooling water channel includes an inlet channel, a circulation chamber, and an outlet channel. The inlet channel is located at the upper part of the circulating cooling chamber and extends from the side near the pump chamber to the other side of the circulating cooling chamber. The outlet channel is located at the lower part of the circulating cooling chamber and extends from the side near the pump chamber to the other side of the circulating cooling chamber. The circulation chamber is located on the side away from the pump chamber, surrounds the main shaft, and connects the inlet channel and the outlet channel.

[0009] Furthermore, the circulating cooling chamber is provided with a removable sealing cover on the side away from the pump chamber, which facilitates the inspection and maintenance of the interior of the circulating cooling chamber.

[0010] Furthermore, the power input end of the main shaft extends to the outside of the circulating cooling chamber and is connected to a drive component for driving the main shaft to rotate.

[0011] Furthermore, the pump chamber includes a housing and a turbine, the housing being detachably connected to the circulating cooling chamber, and the turbine being disposed inside the housing and fixed on the main shaft.

[0012] Furthermore, the housing has a water inlet in the direction of extension of the main shaft and a water outlet in the direction of the turbine side, for realizing the fluid delivery function of the water pump.

[0013] Furthermore, both the circulating cooling chamber and the bottom of the outer shell are equipped with support legs to support the entire water pump device.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0028] Combined with appendix Figures 1-6 The specific implementation process of this utility model of a self-cooling water pump for circulating water channels is as follows:

[0029] A self-cooling water pump for circulating water channels includes a main shaft 1, a circulating cooling chamber 2, and a pump chamber 3. The main shaft 1 is located inside the circulating cooling chamber 2 and its power output end extends into the pump chamber 3; one side of the pump chamber 3 is detachably connected to the circulating cooling chamber 2 by bolts or other fasteners.

[0030] The circulating cooling chamber 2 is equipped with a circulating cooling water channel 4, which includes an inlet channel 6, a circulation chamber 7, and an outlet channel 8. The inlet channel 6 is located at the upper part of the circulating cooling chamber 2 and extends from the side near the pump chamber 3 to the other side of the circulating cooling chamber 2; the outlet channel 8 is located at the lower part of the circulating cooling chamber 2 and extends from the side near the pump chamber 3 to the other side of the circulating cooling chamber 2; the circulation chamber 7 is located on the side away from the pump chamber 3, surrounds the main shaft 1, and connects the inlet channel 6 and the outlet channel 8. A removable sealing cover 9 is provided on the side of the circulating cooling chamber 2 away from the pump chamber 3 to facilitate inspection and maintenance of the interior of the circulating cooling chamber 2.

[0031] The main shaft 1 is rotatably connected to the circulating cooling chamber 2 via a bearing 5. Inside the circulating cooling chamber 2, near the pump chamber 3, there is a bearing 5 seat. The bearing 5 is housed within the bearing 5 seat, and the main shaft 1 passes through the bearing 5 and is rotatably connected to it. The power input end of the main shaft 1 extends to the outside of the circulating cooling chamber 2 and is connected to a drive component 10 (such as a pulley, which can be connected to a drive device such as an engine via a belt) to drive the main shaft 1 to rotate.

[0032] The pump chamber 3 includes a housing 11 and a turbine 12. The housing 11 and the circulating cooling chamber 2 are detachably connected by bolts or other fasteners. The turbine 12 is located inside the housing 11 and fixed on the main shaft 1.
