Description

Technical Field

[0001] This utility model belongs to the field of fluid machinery and equipment technology, specifically an anti-wear and corrosion-resistant water pump. Background Technology

[0002] Water pumps, as essential equipment in industrial production, agricultural irrigation, and urban water supply, are widely used in various fields. Especially in harsh environments, water pumps face multiple challenges, including wear, corrosion, and external impacts. These factors can affect the normal operation of water pumps, shorten their service life, and even lead to equipment failure. Therefore, improving the wear resistance, corrosion resistance, and impact resistance of water pumps is key to enhancing their performance and reliability. Traditional water pump structures often employ single materials or relatively simple protective designs, making them susceptible to wear and corrosion during prolonged use, particularly in environments with chemical media and poor water quality. Furthermore, water pumps may be subjected to external impacts during transportation, installation, and use, which is also a significant factor contributing to pump damage.

[0003] While existing technologies offer some solutions for the wear, corrosion, and impact resistance of water pumps, these traditional protective structures often suffer from limitations such as single protective layers or inadequate protection. For example, common anti-corrosion coatings or protective materials may only provide protection in one aspect, leaving the pump still susceptible to corrosion or wear in complex operating environments. Furthermore, existing pump structures often lack sufficient cushioning and protection against external impacts, making the pump body prone to damage or malfunction, especially during transportation, installation, or operation. Current technologies have not yet provided a perfect solution that comprehensively considers multiple factors such as wear resistance, corrosion resistance, and impact resistance.

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] This application discloses an anti-wear and corrosion-resistant water pump.

[0030] Please see Figures 1 to 6A wear-resistant and corrosion-resistant water pump includes a fixed structure 2 for connecting to different pipes, a support structure 5 for reducing external impact, and a protective structure 4 for enhancing wear and corrosion resistance. The support structure 5 is installed inside the protective structure 4. A round shaft 6 is fixedly connected to the bottom of the protective structure 4, a base 7 is fixedly connected to the bottom of the round shaft 6, and a fixed structure 2 is fixedly connected to the outside of the base 7. The protective structure 4 includes a protective layer 41, a connecting layer 42 is fixedly connected to the bottom of the protective layer 41, an anti-corrosion layer 43 is fixedly connected to the bottom of the connecting layer 42, and a fixed layer 44 is fixedly connected to the bottom of the anti-corrosion layer 43. The support structure 5 includes a baffle 51, a shrink block 53 is fixedly connected to one side of the baffle 51, a connecting block 54 is fixedly connected to the outside of the shrink block 53, an airbag 52 is installed on the outside of the connecting block 54, a guardrail 56 is fixedly connected to the outside of the airbag 52, and a limit block 58 is fixedly connected to the bottom of the airbag 52. The limit block 58 is slidably connected inside a slide groove 57, which is opened inside a base plate 55.

[0031] It should be explained that the fixed structure 2 can flexibly connect to different pipes and adapt to various usage scenarios. The support structure 5 can effectively reduce the damage of external impacts to the water pump. Its baffle 51, together with the shrink block 53, connecting block 54 and airbag 52, can buffer the force during impact. The guardrail 56 further enhances protection. The limit block 58 slides in the groove 57 of the base plate 55 to ensure structural stability. The protective structure 4 can improve the water pump's resistance to wear and corrosion. The protective layer 41 uses a special material to resist wear. The connecting layer 42 strengthens the connection between the layers. The anti-corrosion layer 43 prevents corrosion with its properties. The fixed layer 44 makes the overall structure more stable. Moreover, the protective structure 4 is connected to the base 7 through the round shaft 6. The fixed structure 2 on the outside of the base 7 also cooperates with the water pump as a whole to ensure that the water pump operates stably in complex environments.

[0032] Please see Figures 1 to 6 The fixed structure 2 includes a limiting ring 21. A limiting ring 22 is fixedly connected to one side of the limiting ring 21. A circular ring 23 is fixedly connected to one side of the limiting ring 22. A locking post 24 is fixedly provided on the other side of the circular ring 23. A push rod 25 is fixedly connected to one side of the locking post 24. A slider 26 is slidably connected to the middle of the push rod 25. A circular ring 23 and a limiting ring 21 are fixedly connected to the outer side of the slider 26. A rubber ring 27 is fixedly connected to the outer side of the circular ring 23.

[0033] It should be explained that the limiting ring 21 is connected to the limiting ring 22 for initial limiting, which can prevent excessive displacement of the connecting parts. The ring 23 connects the limiting ring 22 and the locking post 24. The locking post 24 is used to lock and fix external pipes and other components to ensure a stable connection. The push rod 25 is connected to the locking post 24. By pushing the push rod 25, the locking post 24 can be moved to realize the connection or disassembly operation. The slider 26 is slidably connected in the middle of the push rod 25. The ring 23 and the limiting ring 21 are fixed on the outside of the slider 26, which provides guidance and support for the push rod 25 to ensure smooth operation. The rubber ring 27 on the outside of the ring 23 can prevent leakage at the connection and reduce the impact of vibration on the water pump.

[0034] Please see Figures 1 to 6 The bottom of the protective structure 4 is provided with a pump body 1, and a base 7 is provided on one side of the bottom of the protective structure 4.

[0035] It should be explained that the pump body 1 is directly installed at the bottom of the protective structure 4, which can provide all-round protection for the pump body 1, effectively resist external wear and corrosion, and extend the service life of the pump body 1. The bottom side of the protective structure 4 is also equipped with a base 7, which can provide stable support, allowing the entire water pump to be placed stably, ensuring that it remains stable during operation and ensuring the normal operation of the water pump.

[0036] Please see Figures 1 to 6 The pump body 1 is fixedly connected to the outside of the base 7, and a support structure 5 is provided at the upper end of the pump body 1.

[0037] It should be explained that the base 7 is fixedly connected to the pump body 1 on the outside, providing support for the pump body 1 and allowing it to be placed stably, reducing shaking during operation. The support structure 5 set at the upper end of the pump body 1 can further enhance the stability of the pump body 1, and can also buffer external impact forces, protect the internal parts of the pump body 1, and ensure the normal operation of the water pump.

[0038] Please see Figures 1 to 6 The protective layer 41 is made of niobium alloy, the connecting layer 42 is made of tantalum alloy, the anti-corrosion layer 43 is made of polyetheretherketone, and the fixing layer 44 is made of aramid composite material.

[0039] It should be explained that the protective layer 41 is made of niobium alloy, which has high hardness and wear resistance and can resist external friction and scratches. The connecting layer 42 is made of tantalum alloy, which has high strength and good toughness and can stably connect the various layers. The anti-corrosion layer 43 is made of polyetheretherketone, which can effectively isolate corrosive media. The fixing layer 44 is made of aramid composite material, which is lightweight but high strength and can be used for fixing and support, together ensuring the water pump's wear resistance and corrosion resistance.

[0040] Please see Figures 1 to 6 The supporting structure 5 is located above the fixed structure 2, and a circular shaft 6 is provided on the outer side of the fixed structure 2.

[0041] It should be explained that the support structure 5 is set above the fixed structure 2. It can buffer external impact and enhance the overall stability of the water pump. The round shaft 6 set on the outside of the fixed structure 2 can assist in connection and positioning, so that the connection between the various parts of the water pump is tighter and the position is more accurate, ensuring the stable operation of the water pump.

[0042] Please see Figures 1 to 6 The upper end of the protective structure 4 is fixedly connected to the top pipe 3, which is located above the base 7.

[0043] It should be explained that the protective structure 4 is fixedly connected to the top pipe 3. The top pipe 3 is responsible for guiding the water flow in and out and connecting with the external pipe. Moreover, the top pipe 3 is located above the base 7, and the base 7 provides stable support for the entire water pump. The two work together to allow the water pump to be placed stably and to carry out water flow transportation normally.

[0044] The implementation principle of the wear-resistant and corrosion-resistant water pump in this application embodiment is as follows:

[0045] First, when the water pump starts, the jacking pipe 3 guides the water flow into the pump. After the pump pressurizes the water, it guides the water flow out of the pump and connects it to the external pipeline to achieve normal water delivery. During this process, the upper end of the protective structure 4 is firmly connected to the jacking pipe 3. Its protective layer 41, with the high hardness and wear-resistant properties of niobium alloy, initially resists the friction and scraping of impurities that may be carried in the water flow against the upper end of the pump, protecting the upper structure of the pump from wear.

[0046] Secondly, the base 7 provides stable support for the entire water pump, ensuring that the pump can be placed stably during operation and reducing shaking. The support structure 5 is located above the fixed structure 2. When the water pump is subjected to external impact, the baffle 51 in the support structure 5 first absorbs the impact force. Subsequently, the contraction block 53 and the connecting block 54 cooperate to cause the airbag 52 to deform. Through the elastic buffering effect of the airbag 52, the damage to the internal parts of the water pump caused by external impact is effectively reduced. At the same time, the limiting block 58 slides in the groove 57 of the base plate 55 to ensure that the support structure 5 remains stable during impact buffering and will not undergo excessive displacement.

[0047] Finally, the protective structure 4 provides comprehensive protection for the pump body 1. The protective layer 41 resists external abrasion, the connecting layer 42 uses tantalum alloy material to firmly connect the various layers with high strength and good toughness, and the anti-corrosion layer 43 utilizes the excellent corrosion resistance of polyetheretherketone material to isolate corrosive media and prevent corrosion of the pump body 1. The aramid composite material of the fixing layer 44 is lightweight yet high-strength, providing fixed support. The fixing structure 2, through components such as limiting ring 1 21, limiting ring 22, circular ring 23, and locking post 24, flexibly connects to different pipelines, ensuring a stable connection between the pump and external pipelines. The circular shaft 6 provides auxiliary connection and positioning on the outside of the fixing structure 2, making the connection between the various pump components tighter and the position more precise, ensuring stable operation of the pump in complex environments.

[0048] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should be considered within its protection scope.
