Description

Technical Field

[0001] This utility model relates to the field of plastic water pump housing technology, specifically a high-temperature resistant plastic water pump housing. Background Technology

[0002] The plastic water pump housing is the main body shell of the water pump made of plastic. The plastic material makes the housing lighter, easier to transport and install. Plastic has good corrosion resistance and can remain stable in humid or corrosive environments, making it particularly suitable for use in complex environments such as agricultural irrigation, industrial production and urban water supply.

[0003] Most existing plastic water pump housings are made of PPS material. PPS is a high-performance special engineering plastic with excellent heat resistance, chemical corrosion resistance and mechanical properties. However, although water pump housings made entirely of PPS material have a certain degree of heat resistance, they are not convenient for quickly and evenly dissipating heat from the inside of the water pump housing. Therefore, we propose a high-temperature resistant plastic water pump housing. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a high-temperature resistant plastic water pump housing. Example 1

[0025] Combination Figure 1-4 As shown, the present invention provides a high-temperature resistant plastic water pump housing, comprising: a pump housing body 100 and a heat dissipation assembly 200; the pump housing body 100 includes an inlet pipe 101 and an outlet pipe 102 at its front end and one side; the heat dissipation assembly 200 includes multiple sets of inner grooves 201 arranged on the outer side of the pump housing body 100, outer grooves 202 extending from the inner side of each inner groove 201, a concave ring 203 on the inner side of each outer groove 202, inner heat dissipation fins 204 movably installed in each inner groove 201, outer heat dissipation fins 205 movably installed in each outer groove 202, a fixing ring 206 movably installed in each concave ring 203, and an inlet pipe 206. An inner clamping cylinder 207 is movably installed at the outer end of the pipe 101. Multiple sets of connecting rods 208 are also fixedly installed on the outer side of the inner clamping cylinder 207. An outer clamping ring 209 is also fixedly installed at the outer end of the connecting rod 208. An internal thread 210 is provided at the inner end of the inner clamping cylinder 207. An external thread 211 is provided on one side of the outer end of the liquid inlet pipe 101. The external thread 211 and the internal thread 210 are threadedly connected. The inner heat dissipation fins 204 are all fixedly connected to the inner outer heat dissipation fins 205. The outer heat dissipation fins 205 are all fixedly connected to the inner fixing ring 206. The inner groove 201 is a T-shaped structure, and the outer groove 202 is a strip-shaped structure.

[0026] Specifically, the plastic water pump housing is a water pump body shell made of plastic. The inner heat dissipation fins 204 and outer heat dissipation fins 205 installed in the inner groove 201 and outer groove 202 on the outer side of the pump housing body 100 are arranged on the outer side and front end of the pump housing body 100. This allows for the conduction of heat generated during operation within the pump housing body 100 and its dissipation to the outside, thereby reducing the operating temperature within the pump housing body 100 and improving its high-temperature resistance. Simultaneously, the inner heat dissipation fins 204 and outer heat dissipation fins 205 arranged on the outer side and front end of the pump housing body 100 also act as reinforcing ribs at the upper end of the pump housing body 100, further enhancing its overall strength. The inner clamping cylinder 207 installed at the outer end of the inlet pipe 101 can also... The outer clamping ring 209 at the outer end clamps the inner heat dissipation fins 204 and 205 in the inner slot 201 and outer slot 202 from the outside, thereby ensuring their stability after installation and ensuring their stability during use. The concave ring 203 on the inner side of the outer slot 202 is mainly used for the installation of the inner end fixing ring 206 of the inner heat dissipation fins 204 and 205, thereby ensuring the stability of the inner heat dissipation fins 204 and 205 during the subsequent clamping of the inner clamping cylinder 207. The internal thread 210 at the inner end of the inner clamping cylinder 207 and the external thread 211 at the outer end of the liquid inlet pipe 101 are mainly used for the threaded locking installation of the inner clamping cylinder 207 and the outer end clamping ring 209, thereby stably clamping the inner heat dissipation fins 204 and 205.

[0027] Working principle and usage process of this utility model:

[0028] During use, the inner heat dissipation fins 204 and outer heat dissipation fins 205 arranged in the outer inner groove 201 and front outer groove 202 of the pump housing body 100 can conduct heat from the inner end of the pump housing body 100 during use to the sides and front of the pump housing body 100. After being conducted to the upper ends of the inner heat dissipation fins 204 and outer heat dissipation fins 205, heat is dissipated to the outside, thereby reducing the temperature of the inner end of the pump housing body 100 during use and improving its high temperature resistance. At the same time, the inner heat dissipation fins 204 and outer heat dissipation fins 205 arranged in the inner inner groove 201 and front outer groove 202 of the pump housing body 100 can conduct heat from the inner end of the pump housing body 100 during use to the outside of the pump housing body 100. The internal heat dissipation fins 204 and external heat dissipation fins 205 can also serve as reinforcing ribs at the outer end of the pump housing body 100 to improve the overall strength of the pump housing body 100. The internal clamping cylinder 207 and external clamping ring 209, which are threaded and tightened at the outer end of the liquid inlet pipe 101, can also be pressed between the internal heat dissipation fins 204 and external heat dissipation fins 205 and the outer end of the fixing ring 206, thereby ensuring the stability of the internal heat dissipation fins 204 and external heat dissipation fins 205 during use, so as to fit tightly against the pump housing body 100 and perform better heat conduction and heat dissipation.
