Description

Technical Field

[0001] This utility model relates to the field of pump technology, and in particular to an impeller guide pump suitable for refrigeration systems. Background Technology

[0002] Refrigerant is the substance that circulates in a refrigeration system, transferring heat through its phase change (vaporization and condensation) to achieve the purpose of cooling or heating. It absorbs heat and vaporizes in the evaporator, and releases heat and liquefies in the condenser, completing a thermodynamic cycle. Common refrigerants include ammonia, Freon-based refrigerants, and water, and their selection must consider environmental friendliness, safety, and economy. To transport the refrigerant to its designated location, a suitable impeller pump for the refrigeration system is essential.

[0003] Impeller-driven guide pumps for refrigeration systems are high-efficiency, energy-saving devices. Their core components include an impeller and guide vanes. The impeller generates centrifugal force through high-speed rotation, causing the refrigerant to flow continuously within the pump and gain energy, thus achieving the functions of delivery and pressurization. The guide vanes guide the direction of the fluid, improving pump efficiency and reducing energy loss. These pumps typically employ a closed impeller design to ensure efficient liquid circulation within the pump, while also possessing good sealing and corrosion resistance, making them suitable for liquid delivery in refrigeration systems.

[0004] Although existing impeller guide pumps can adapt to most operating environments, the required flow rate varies when conveying different refrigerants. This necessitates replacing the guide vanes with appropriate models to meet the operational requirements. Therefore, an impeller guide pump suitable for refrigeration systems is proposed.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of an impeller-driven flow pump suitable for refrigeration systems, comprising a housing 1, inside which a pump body 13 is installed, enabling the overall operation of the equipment. An inlet pipe 7 is fixedly connected to one side of the pump body 13, through which liquid enters. An outlet pipe 6 is fixedly connected to the top of the inlet pipe 7, through which the liquid, after flow guidance, is output. A flow guiding mechanism is installed inside the inlet pipe 7 to adapt to different working requirements. A hinge 12 is fixedly connected to the outside of the housing 1, facilitating the opening of the cover 3. The other end of the hinge 12 is fixedly connected to the cover 3, effectively protecting the internal equipment from damage. A snap-fit ​​mechanism is installed on the outside of the housing 1, allowing the cover 3 to be more tightly secured to the top of the housing 1. The flow guiding mechanism includes a quick-release assembly and a fixing assembly. The fixing assembly includes an impeller body 21, which is rotatably connected to the pump body 1. At one end of the pump body 13, the impeller body 21 allows the liquid to overcome resistance and enter the next area. A guide plate 17 is slidably connected to the outside of the impeller body 21, allowing the liquid to flow to the outlet pipe 6 at different speeds. A fixing rod 18 is fixedly connected to the outside of the guide plate 17. A sliding hole 20 is opened in the middle of the impeller body 21, and the fixing rod 18 is engaged with the sliding hole 20. The fixing rod 18 allows the guide plate 17 to be more firmly fixed to the outside of the impeller body 21. The fixing assembly includes a bolt 19, which is fixedly connected to the middle of the impeller body 21. A cap 16 is threaded to the outside of the bolt 19, which clamps the guide plate 17 in the middle to ensure that the guide plate 17 can operate more stably during operation. A knob 15 is fixedly connected to the outside of the cap 16, allowing the operator to open the cap 16 more easily.

[0035] Reference Figure 1 , Figure 3 and Figure 5The latching mechanism includes a plug-in assembly and a stabilizing assembly. The plug-in assembly includes a housing 2, which is fixedly connected to the outside of the housing 1. The housing 2 effectively protects the internal parts from damage. A pin 24 is slidably connected inside the housing 2, which stabilizes the cover 3 above the housing 1. A limit plate 22 is fixedly connected to the outside of the pin 24 to prevent the pin 24 from slipping out and causing damage to the parts. A spring 23 is sleeved on the outside of the pin 24, and the elasticity of the spring 23 helps to stabilize the cover 3. This allows the pin 24 to quickly return to its original position, improving work efficiency. The stabilizing component includes a plate 4, which is fixedly connected to the outside of the cover 3. The plate 4 allows the pin 24 to be stably connected to the cover 3. A slot 14 is provided in the middle of the plate 4, and the pin 24 is engaged with the slot 14. By inserting the pin 24 into the slot 14, the cover 3 is stabilized, protecting the internal parts from damage. At the same time, it can also be used to inspect the internal pump body 13 and clean the fan 10 and filter plate 11 installed on the outside of the housing 1.

[0036] Reference Figures 1-6 A fan 10 is installed on the outside of the housing 1. Since the equipment is used for a refrigeration system, cooling it with the fan 10 allows the pump body 13 to operate better, improving efficiency and quality. A filter plate 11 is fixedly connected to the outside of the housing 1. The filter plate 11 discharges hot air without affecting the operation of the pump body 13 inside. A base 9 is fixedly connected to the bottom of the housing 1 for easy installation of the entire equipment. A retaining plate 8 is slidably connected inside the housing 1. The retaining plate 8 can hold the pump body 13 inside the housing 1, maintaining the stability of the pump body 13 during operation. A slider 25 is fixedly connected to the outside of the retaining plate 8. A sliding groove 26 is opened inside the housing 1. The slider 25 is slidably connected inside the sliding groove 26. Through the slider 25 and the sliding groove 26, the retaining plate 8 can be more smoothly inserted into the housing 1, while ensuring the stability between the pump body 13 and the housing 1. A groove 5 is opened in the middle of the retaining plate 8, which allows the operator to more easily pull out and put in the retaining plate 8.

[0037] Working principle: First, when different models of guide vanes 17 are needed to meet the required flow rate, the cover 16 connected to the knob 15 will rotate together by turning the knob 15. Since the cover 16 is threadedly connected to the bolt 19 on the impeller body 21, the cover 16 will rotate. After removing the cover 16, slide the guide vane 17 out of the sliding hole 20 on the impeller body 21, insert the required model of guide vane 17 into the sliding hole 20 and press it firmly. Then turn the knob 15 again to firmly fix the cover 16 on the outside of the guide vane 17, so as to realize the quick replacement and installation of the guide vane 17.

[0038] Secondly, when it is necessary to inspect the pump body 13 inside the housing 1, the pin 24 can be pulled. At this time, the limiting plate 22 will move with the pin 24 and squeeze the spring 23. When the pin 24 is completely pulled out of the slot 14, the cover 3 is opened along the hinge 12. At this time, the pump body 13 inside can be inspected. At the same time, the filter plate 11 and the fan 10 can also be cleaned. After the work is completed, the cover 3 is put back on, and the hand holding the pin 24 is released. Due to the elasticity, the spring 23 will quickly return to the center and insert the pin 24 into the slot 14.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
