Description

Technical Field

[0001] This utility model belongs to the field of water pumps, and more specifically, it relates to miniaturized permanent magnet centrifugal pumps. Background Technology

[0002] Miniaturized permanent magnet centrifugal pumps are the core power components of fluid transport systems. They are mainly used for liquid circulation and transport. While ensuring stable transport pressure and flow, they adapt to small installation spaces with a compact and lightweight structure, and maintain the stable operation of the fluid transport system.

[0003] When traditional permanent magnet centrifugal pumps operate in low-temperature environments, soft, lightweight, and slightly viscous flocculent substances and colloids are easily generated in the liquid. After these impurities enter the pump body, they easily adhere to the smooth inner wall, gradually accumulating and causing blockage of the flow channel. At the same time, bubbles generated by fluid movement disturbances are easy to accumulate inside the pump cavity, affecting the stable operation of the pump body. Utility Model Content

[0004] To solve the aforementioned technical problems, the purpose and effectiveness of this miniaturized permanent magnet centrifugal pump are achieved through the following specific technical means:

[0005] Its structure includes a water pump, a drive end, a power end, a base, a water pump seat, and a connecting shaft. The power end is connected to the water pump through the connecting shaft. The drive end is fixed to the surface of the power end for control. The base is welded to the bottom of the power end, and the water pump seat is fixed to the bottom of the water pump.

[0006] The water pump includes an inlet channel, a pump body, an outlet channel, a power shaft, a power blade, a connecting grid, and an air bubble channel. The inlet channel is connected to the outlet channel through the connecting grid. The power blade is sleeved on the outer surface of the power shaft and rotates synchronously. The air bubble channel is fixed to the inner wall surface of the pump body. The inlet channel and the outlet channel form a complete liquid flow path.

[0007] As a further improvement of this utility model, the water inlet includes a sealing ring, a thread, a connecting shell, and a dividing ring. The sealing ring and the thread are an integrated structure. The thread is fixed to the connecting shell. The dividing ring is fixed to the inner ring surface of the connecting shell. The sealing ring can improve the sealing performance of the connection between the water inlet and the external pipeline.

[0008] As a further improvement of this utility model, the dividing ring includes a groove channel, a protrusion, a spacer block, and a dividing head. A groove channel is formed between two spacers. The protrusion is connected between two spacers. The dividing head is fixed to the surface of the spacer block. The groove channel can guide the liquid flow to enhance the flushing force.

[0009] As a further improvement of this utility model, the power end controls the synchronous rotation of the power shaft through the connecting shaft. The power end can run after being powered on. The water pump is used to transport liquid. The connecting shaft can ensure the coaxiality and stability of power transmission.

[0010] As a further improvement of this utility model, the power blade centrifugally transports the liquid, throwing the bubbles onto the surface of the bubble channel for processing. The centrifugal force generated by the rotation of the power blade can achieve liquid pressurization and transportation.

[0011] As a further improvement of this utility model, the sealing ring is used to improve the sealing effect when the water inlet is connected to the external connecting pipe. The dividing ring has a circular structure, and the sealing ring can prevent liquid leakage and the entry of external impurities.

[0012] As a further improvement of this utility model, the dividing head has a V-shaped structure, which uses water jet force to assist in cutting flocculent material. The groove between the spacers guides and increases the water jet force, and the protrusion forms a drop in the groove, preventing flocculent material from adhering to the flat surface. The V-shaped dividing head can improve the efficiency and effect of impurity cutting.

[0013] As a further improvement of this utility model, the bubble channel includes a protective shell, a drop groove, and an impact block. The drop groove and the protective shell are an integrated structure. The impact block is installed inside the drop groove. The protective shell can protect the internal tank structure from damage caused by liquid erosion.

[0014] As a further improvement of this utility model, the drop groove and the protective shell are connected by a slope. The drop groove is in an inclined state and is evenly distributed in a circle. Each group of drop grooves has five evenly distributed grooves. The inclined and evenly distributed drop grooves can achieve circumferential degassing.

[0015] As a further improvement of this utility model, the drop groove and the impact block form an uneven shape inside the protective shell to assist the bubbles in floating. The uneven shape formed by the drop groove and the impact block can destroy the liquid layer attached to the wall and cause the bubbles to detach quickly.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In low-temperature winter environments, soft, lightweight, and slightly viscous flocculent substances and colloids that are easily generated in liquids can be efficiently broken, dispersed, and directionally guided by the liquid flow force and the synergistic effect of the dividing ring when they enter the water pump. This effectively prevents them from accumulating, clumping, and adhering in the flow channel, ensuring smooth flow inside the water pump and maintaining stable liquid delivery efficiency.

[0018] 2. When bubbles are generated in the liquid due to running disturbances, this structure can rely on the centrifugal force generated by the rotation of the power blades, in conjunction with the bubble channel, to peel off, guide and disperse the bubbles, prevent the bubbles from adhering to the inner wall of the pump cavity, eliminate the interference of bubbles on the magnetic field, reduce operating noise and vibration, and improve the operating stability and service life of the power end.

[0019] Third, it effectively avoids interference to the rotation of the power blades caused by the agglomeration of flocculent matter and the adhesion of air bubbles, reduces the risk of abnormal noise, jamming and wear inside the pump body, extends the overall service life of the water pump, and improves the reliability and stability of the fluid transportation system in long-term operation.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] Example 1: As shown in the attached document Figure 1 To be continued Figure 7 As shown:

[0033] This utility model provides a miniaturized permanent magnet centrifugal pump, the structure of which includes a water pump 1, a drive end 2, a power end 3, a base 4, a water pump seat 5, and a connecting shaft 6. The power end 3 is connected to the water pump 1 through the connecting shaft 6. The drive end 2 is fixed to the surface of the power end 3 for control. The base 4 is welded to the bottom of the power end 3. The water pump seat 5 is fixed to the bottom of the water pump 1.

[0034] The water pump 1 includes an inlet channel 11, a pump body 12, an outlet channel 13, a power shaft 14, a power blade 15, a connecting grid 16, and an air bubble channel 17. The inlet channel 11 is connected to the outlet channel 13 through the connecting grid 16. The power blade 15 is sleeved on the outer surface of the power shaft 14 and rotates synchronously. The air bubble channel 17 is fixed to the inner wall surface of the pump body 12. The inlet channel 11 and the outlet channel 13 form a complete liquid flow path. The power blade 15 rotates with the power shaft 14 to achieve liquid pressurization and transportation.

[0035] The water inlet 11 includes a sealing ring 21, a thread 22, a connecting shell 23, and a dividing ring 24. The sealing ring 21 and the thread 22 are an integrated structure. The thread 22 is fixed to the connecting shell 23. The dividing ring 24 is fixed to the inner ring surface of the connecting shell 23. The sealing ring 21 can improve the sealing performance of the connection between the water inlet 11 and the external pipeline. The thread 22 facilitates the quick assembly and disassembly of the water inlet 11.

[0036] The dividing ring 24 includes a groove channel 31, a protrusion 32, a spacer block 33, and a dividing head 34. The groove channel 31 is formed between two spacer blocks 33. The protrusion 32 is connected between two spacer blocks 33. The dividing head 34 is fixed to the surface of the spacer block 33. The groove channel 31 can guide the liquid flow to enhance the flushing force. The drop formed by the protrusion 32 can destroy the impurity adhering to the substrate.

[0037] The power end 3 controls the synchronous rotation of the power shaft 14 through the connecting shaft 6. The power end 3 can run after being powered on. The water pump 1 is used to transport liquid. The connecting shaft 6 can ensure the coaxiality and stability of power transmission. The water pump 1 can continuously transport liquid to achieve stable fluid transport.

[0038] The power blade 15 centrifugally transports the liquid, throwing bubbles onto the surface of the bubble channel 17 for processing. The centrifugal force generated by the rotation of the power blade 15 can achieve liquid pressurization and transportation. The centrifugal transportation method of the power blade 15 can increase the liquid transportation pressure and flow rate.

[0039] The sealing ring 21 is used to improve the sealing effect when the water inlet 11 is connected to the external connecting pipe. The dividing ring 24 has a circular structure. The sealing ring 21 can prevent liquid leakage and the entry of external impurities. The dividing ring 24 has a circular structure and can fit perfectly with the inner wall of the water inlet 11.

[0040] The dividing head 34 has a V-shaped structure, which assists in cutting flocculent material through water jet force. The groove channel 31 between the spacer blocks 33 guides and increases the water jet force. The protrusion 32 forms a drop in the groove channel 31 to prevent flocculent material from adhering to the flat surface. The V-shape of the dividing head 34 can improve the efficiency and effect of impurity cutting. The groove channel 31 can make the liquid form a directional jet to enhance the flushing ability.

[0041] The specific usage and function of this embodiment are as follows:

[0042] In this invention, external pipes are connected to the inlet channel 11 and the outlet channel 13 respectively. The sealing ring 21 and the thread 22 together achieve the sealing and stable connection of the pipe body. The drive end 2 is energized and the power end 3 is started. The power end 3 drives the power shaft 14 to rotate synchronously through the connecting shaft 6, which in turn drives the power blade 15 to rotate at high speed. The liquid introduced into the inlet channel 11 is pressurized and transported to the outlet channel 13 by the centrifugal force generated by the rotation of the power blade 15. When the liquid produces flocculent material in a low temperature environment and flows through the inlet channel 11 with the water flow, the flocculent material will be cut and broken by the dividing head 34 on the dividing ring 24 under the impact of the water flow, so as to avoid the flocculent material from accumulating and agglomerating and adhering to the inner wall of the flow channel. The flow channel formed between the spacer blocks 33 can enhance the liquid impact and realize directional flow. The concave and convex surfaces formed by the protrusions 32 further prevent the flocculent material from adhering, so that the broken flocculent material can pass smoothly through the connecting grid 16 with the water flow and be transported to the outlet channel 13 for discharge under the centrifugal force of the power blade 15.

[0043] Example 2: As shown in the attached document Figure 8 To be continued Figure 10 As shown:

[0044] The bubble channel 17 includes a protective shell 71, a drop groove 72, and an impact block 73. The drop groove 72 and the protective shell 71 are an integrated structure. The impact block 73 is installed in the drop groove 72. The protective shell 71 can protect the internal tank structure from liquid erosion and damage. The drop groove 72 can assist the bubbles to detach.

[0045] The drop groove 72 and the protective shell 71 are connected by a slope. The drop groove 72 is in an inclined state and is evenly distributed in a circle. Each group of drop grooves 72 has five evenly distributed ones. The inclined and evenly distributed drop grooves 72 can realize circumferential degassing. The five evenly distributed structures of the impact block 73 can improve the uniformity and efficiency of bubble treatment.

[0046] The drop groove 72 and the impact block 73 form an uneven shape inside the protective shell 71 to help the bubbles float. The uneven shape formed by the drop groove 72 and the impact block 73 can break the liquid layer attached to the wall and make the bubbles detach quickly. The uneven structure of the impact block 73 can reduce the adhesion and accumulation of bubbles.

[0047] The specific usage and function of this embodiment are as follows:

[0048] In this invention, when bubbles are generated by the liquid due to operational disturbance, they will enter the connecting compartment 16 through the inlet channel 11 along with the liquid. Under the centrifugal force generated by the rotation of the power blade 15, the bubbles with a density less than that of the liquid float towards the outer ring of the pump body and adhere to the surface of the bubble channel 17. The drop groove 72 provided on the surface of the bubble channel 17 can allow the bubbles to detach from the wall plane. The impact block 73 further increases the drop height of the drop groove 72 and enhances the bubble disturbance effect, assisting the bubbles to quickly fall off the wall and converge towards the central area, thereby preventing the bubbles from remaining on the outer ring of the pump body and adhering to the inner wall of the pump body, ensuring stable operation of the power end.

[0049] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
