Description

Technical Field

[0001] This utility model belongs to the field of deep well pump technology, specifically relating to a high-flow-rate, high-efficiency stamped stainless steel deep well pump. Background Technology

[0002] The most distinctive feature of a deep well pump is that it integrates the electric motor and the pump into one unit. It is a type of pump that is immersed in a groundwater well to draw and transport water, and it is widely used in farmland irrigation and drainage, industrial and mining enterprises, urban water supply and drainage, and sewage treatment.

[0003] Existing deep well pumps typically increase water flow velocity and flow rate by adding impellers. This leads to an increase in the height of the deep well pump to accommodate the distribution of multiple impellers. When the height of the deep well pump is too high, the upper part of the pump is prone to excessive stress, resulting in bending and deformation. In severe cases, it may even break, posing a serious safety hazard. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a high-flow-rate, high-efficiency stamped stainless steel deep well pump, which can effectively increase the water flow rate without adding an impeller and ensure the high performance of the deep well pump.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a high-flow-rate, high-efficiency stamped stainless steel deep well pump, including an inlet, an outlet, a shaft, multiple pump casings, and multiple sets of impellers. The shaft is rotatably mounted on the inlet. The multiple pump casings are interconnected and stacked on the upper part of the pump body, and the bottommost pump casing is connected to the inlet. The outlet is connected to the topmost pump casing. The multiple sets of impellers are rotatably mounted in the multiple pump casings and are set on the shaft. The pump casings are provided with multiple guide vanes, which are equidistantly arranged around the impellers. The impeller includes blades and upper and lower covers fixed to the upper and lower ends of the blades. The blades are stamped from stainless steel to form integrated wave-shaped blades.

[0006] The shaft is provided with a tapered sleeve, and the impeller is provided with a tapered inner hole that mates with the tapered sleeve.

[0007] Each pump casing is equipped with a bushing fitted onto the shaft.

[0008] The inner hole of the bushing is octagonal, forming a sand passage between it and the outer wall of the shaft.

[0009] A cleaning plate is installed in the water inlet and is raised and lowered. An elastic element is installed at the bottom of the water inlet and is fixedly connected to the bottom of the cleaning plate. Pull ropes are connected to the two symmetrical sides of the cleaning plate and are installed at the height of the pump body and extend upward.

[0010] The outer wall of the outlet is provided with a limiting ring, the pull rope passes through the limiting ring, and a limiting block is provided below the limiting ring on the pull rope.

[0011] The cleaning plate is equipped with brushes on its sidewalls.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model discloses a high-flow-rate, high-efficiency stamped stainless steel deep well pump. Its blades are formed by stamping stainless steel into integrated wave-shaped blades. Compared with assembled blades, the one-piece molding provides better robustness, smoother flow channels, and fewer integrated wave-shaped blades that are less prone to detachment. The flow channel angle is stable, resulting in stable performance and smoother flow channels. Furthermore, the addition of guide vanes further guides the flow, increasing its smoothness. A smoother flow channel leads to increased flow rate, effectively improving water flow without adding an impeller, thus ensuring the high performance of the deep well pump.

[0019] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0020] like Figures 1-4As shown, this embodiment provides a high-flow-rate, high-efficiency stamped stainless steel deep well pump, including an inlet 1, an outlet 2, a shaft 3, multiple pump casings 4, and multiple sets of impellers 5. The shaft 3 is rotatably mounted on the inlet 1. The multiple pump casings 4 are interconnected and stacked on the pump body, with the bottommost pump casing 4 connected to the inlet 1 and the outlet 2 connected to the topmost pump casing 4. The multiple sets of impellers 5 are rotatably mounted inside the multiple pump casings 4 and are mounted on the shaft 3. The pump casings 4 are provided with multiple guide vanes 7, which are equidistantly arranged around the impellers 5. The impellers 5 include blades and upper and lower covers fixed to the upper and lower ends of the blades. The blades are stamped from stainless steel to form integrated wave-shaped blades 6. Specifically, the shaft 3 is provided with a tapered sleeve, and the impellers 5 are provided with tapered inner holes that mate with the tapered sleeve. Its blades are formed by stamping stainless steel into integrated wave-shaped blades 6. Compared with assembled blades, the one-piece molding has better sturdiness, smooth flow channel, and fewer integrated wave-shaped blades 6 that are not easy to fall off. The flow channel angle is stable, the performance is stable, and the flow channel is smoother. Furthermore, the flow guide blades 7 are set to further guide the flow and increase the flow channel smoothness. The smooth flow channel increases the flow rate, effectively improving the water flow rate without adding impeller 5, thus ensuring the high performance of the deep well pump.

[0021] Furthermore, each pump casing 4 is provided with a bushing 8 fitted onto the shaft 3. Specifically, the inner hole of the bushing 8 is octagonal, forming a sand passage 9 between it and the outer wall of the shaft 3. The sand passage 9 is provided so that sand particles can be discharged through the sand passage 9 after entering, preventing wear on the shaft 3 and reducing friction between the shaft 3 and the bushing 8 to reduce the load.

[0022] Furthermore, a cleaning plate 10 is installed vertically inside the inlet 1, and an elastic element 12 is installed at the bottom of the inlet 1. The elastic element 12 is fixedly connected to the bottom of the cleaning plate 10. Pull ropes 11 are connected to the two symmetrical sides of the cleaning plate 10, and the pull ropes 11 extend upwards to the height of the pump body. Specifically, a rotating connector connected to the motor drive is provided inside the inlet 1. The rotating connector is connected to the shaft 3 for transmission. By rotating the connector to the motor, the shaft 3 drives the impeller 5 to rotate. After long-term use, sand and dirt easily accumulate on the filter screen outside the inlet 1. Pulling the pull rope 11 causes the cleaning plate 10 to stretch the elastic element 12 upwards. After the elastic element 12 is stretched to its maximum extent, the pull rope 11 is released, and the elastic force of the elastic element 12 pulls the cleaning plate 10 downwards, thereby squeezing the water in the inlet 1 outwards and flushing the sand and dirt on the filter screen.

[0023] Furthermore, a limiting ring 13 is provided on the outer wall of the outlet 2, and the pull rope 11 is arranged through the limiting ring 13. A limiting block 14 is provided below the limiting ring 13 for the pull rope 11. The pulling direction of the pull rope 11 is limited by the limiting ring 13, and the limiting block 14 is used to prevent excessive pulling.

[0024] Furthermore, a brush 15 is installed on the side wall of the cleaning plate 10. The inner wall of the filter screen is cleaned by the brush 15. The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from the spirit and scope of the invention. All such changes and modifications fall within the scope of the present invention as claimed, which is defined by the appended claims and their equivalents.
