[0023] A vertical stainless steel stamping centrifugal pump is a centrifugal pump made of stainless steel materials through a stamping process. The pump body and main components are usually made of stainless steel materials to ensure corrosion resistance and durability. Vertical stainless steel stamping centrifugal pumps are usually designed with an efficient hydraulic model to improve the pump's performance and service life. They can provide high efficiency and energy-saving features and are suitable for various industrial and civil applications.

[0024] At present, the Chinese utility model patent application with a publication date of February 21, 2023 and a publication number of CN 218509814U provides a vertical centrifugal pump, which includes a bottom support frame, a bottom support seat, a fixing component, a shock absorption component, a dust-proof cover and a centrifugal pump body. The bottom support seat is arranged in the middle of the bottom support frame. The fixing components are symmetrically arranged at the upper left and right ends of the top of the bottom support seat. The lower end of the centrifugal pump body is arranged on the bottom support seat. The fixing component is engaged with the lower end of the centrifugal pump body. The shock absorption components are symmetrically arranged at the left and right ends of the bottom support seat. The shock absorption component is engaged with the middle of the centrifugal pump body. The dust-proof cover is arranged on the shock absorption component. An electric motor is arranged at the upper end of the centrifugal pump body, and the dust-proof cover protects the electric motor. The utility model relates to the technical field of centrifugal pumps, and specifically provides a vertical centrifugal pump that is easy to install and can dust-proof the electric motor.

[0025] Based on this, in order to improve the vertical centrifugal pump in the related art, which cannot prevent the impeller and the pump casing from being worn by solid particles in the liquid when the pump transports the liquid, which may lead to a decrease in the pump's efficiency and an increase in operating costs, the embodiments of this application provide the following solutions.

[0026] Please refer to Figures 1 to 3 , the embodiments of this application provide a vertical stainless steel stamping centrifugal pump, which includes a bracket 1, a water storage tank 3, a filtering component 2 and a pump body mechanism 5. The water storage tank 3 is arranged on the bracket 1. The filtering component 2 is arranged on the water storage tank 3. The pump body mechanism 5 is arranged on the water storage tank 3.

[0027] In some embodiments, please refer to Figures 1 to 2, the pump body mechanism 5 includes a motor 51, a pump housing 52 and an impeller 54. The pump housing 52 is arranged on the water storage tank 3. A first connection hole and a second connection hole are formed in the pump housing 52. The first connection hole communicates with the water outlet hole on the water storage tank 3. A water outlet pipe 6 is arranged on the pump housing 52. The water outlet pipe 6 is connected to the pump housing 52 through the second connection hole. The motor 51 is arranged on the pump housing 52. The impeller 54 is arranged in the pump housing 52. The impeller 54 is in transmission connection with the rotating shaft 53 of the motor 51. The pump body mechanism 5 further includes a cooling fan 55 and a cooling bearing 56. The cooling bearing 56 is arranged on the motor 51. The cooling fan 55 is arranged on the motor 51. The cooling fan 55 is in transmission connection with the cooling bearing 56 of the motor 51.

[0028] With such a setting, when an operator uses a vertical stainless steel stamping centrifugal pump, when the centrifugal pump is started, the impeller 54 is key-connected to the output shaft of the motor 51, and the motor 51 drives the impeller 54 of the pump to rotate at a high speed. The impeller 54 is usually installed inside the pump housing 52 and is the core component of the pump. The rotation of the impeller 54 forms a low-pressure area at the center of the impeller 54, which prompts the liquid to be sucked into the impeller 54 from the water inlet of the pump. This process is achieved by the pressure difference between the water inlet of the pump and the low-pressure area at the center of the impeller 54. After the liquid enters the impeller 54, with the rotation of the impeller 54, the liquid is accelerated and obtains kinetic energy. Part of the kinetic energy obtained by the liquid in the impeller 54 is converted into pressure energy. When the liquid is thrown out from the outer edge of the impeller 54 and enters the pump housing 52, its speed decreases, and the kinetic energy is further converted into pressure energy. Inside the pump housing 52, the pressure of the liquid further increases, and finally it is discharged out of the pump through the water outlet of the pump and transported to the place where it is needed. And when the centrifugal pump is started, the motor 51 drives the cooling bearing 56 to rotate. The cooling bearing 56 is key-connected to the output shaft of the motor 51. The cooling fan 55 and the cooling bearing 56 are coaxially connected. The cooling fan rotates and at the same time dissipates the heat from the ventilation plate on the stainless steel housing 23.

[0029] In some embodiments, please refer to Figures 1 to 3, the filtering assembly 2 includes a filter cartridge 24, a water inlet pipe 21, a connecting pipe 22 and a housing 23. The water storage tank 3 is arranged on the bracket 1. The water storage tank 3 is provided with a water inlet hole and a water outlet hole. The housing 23 is provided with a first through hole and a second through hole. One end of the connecting pipe 22 is communicated with the water storage tank 3 through the water inlet hole. The housing 23 is communicated with the other end of the connecting pipe 22 through the first through hole. The filter cartridge 24 is provided with a connecting hole. The filter cartridge 24 is arranged at the end of the connecting pipe 22 away from the water storage tank 3, and the filter cartridge 24 is communicated with the connecting pipe 22 through the connecting hole. The water inlet pipe 21 is arranged on the housing 23, and the water inlet pipe 21 is communicated with the housing 23 through the second through hole. The pump body mechanism 5 is arranged on the water storage tank 3, and the input end of the pump body mechanism 5 is communicated with the water outlet hole. The filtering assembly 2 further includes a cover 25. The bottom of the housing 23 is provided with a discharge port. The cover 25 is threadedly connected to the housing 23, and the cover 25 plugs the discharge port. The filtering assembly 2 further includes a sealing gasket 26. The sealing gasket 26 is arranged on the cover 25, and one end of the sealing gasket 26 away from the cover 25 abuts against the housing 23.

[0030] With such an arrangement, when the centrifugal pump is started, due to the pressure difference between the liquid passing through the pump's water inlet and the low-pressure area at the center of the impeller 54, when sucking in water at the water inlet, the liquid first enters the housing 23 through the water inlet pipe 21. Larger solid particles are filtered out by the filter cartridge 24, and the larger solid particles are collected in the cover 25. When the liquid passes through the cover 25, the liquid is sealed by the sealing gasket 26 to prevent liquid leakage. After the solid particles are filtered, the liquid enters the water storage tank 3 through the connecting pipe 22 connecting the filter cartridge 24 and the first through hole. By using the filter cartridge 24 to filter larger particles, the probability of solid particles entering the impeller 54 can be reduced, thereby improving the pump's efficiency and reducing operating costs.

[0031] In some embodiments, an anti-backflow assembly 4 is arranged at the end of the connecting pipe 22 away from the housing 23. The anti-backflow assembly 4 includes a connecting shaft 41, a fixing frame 42, a rotating frame 43 and a blocking plate 44. The fixing frame 42 is fixedly arranged at the end of the connecting pipe 22 away from the housing 23. The fixing frame 42 is provided with a connecting hole, and the connecting shaft 41 passes through the fixing frame 42 through the connecting hole. The rotating frame 43 is arranged on the connecting shaft 41, and the blocking plate 44 is fixedly arranged on the rotating frame 43. The thickness of one end of the blocking plate 44 close to the connecting shaft 41 is smaller than the thickness of the end away from the connecting shaft 41.

[0032] With such a setting, the liquid enters the anti-backflow component 4. The liquid presses the sealing plate 44, causing the sealing plate 44 to rotate. At the same time, the fixed frame 42 and the rotating frame 43 rotate, and the liquid enters the water storage tank 3. When the centrifugal pump is closed, the cover 25 can be unscrewed by threads to clean the solid particles collected in the cover 25. At the same time, a certain amount of liquid is accumulated in the water storage tank 3. When the liquid flows back, the sealing plate 44 falls under the action of gravity to block the water inlet, thereby reducing the liquid backflow and causing the liquid to accumulate in the water storage tank 3. The next time the centrifugal pump is driven, the time difference of the liquid flowing from the filtration component 2 is reduced, improving the working efficiency. The above description is only the preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
