Description

Technical Field

[0001] The utility model relates to the technical field of drive pumps, in particular to a magnetic drive pump. Background Art

[0002] Magnetic drive pumps, or magnetic pumps, are unique in their principle of permanent magnetic transmission technology, achieving contactless transmission of torque, thus setting a new standard for seal-free pumps in the pump industry. However, during its operation, we also found some potential problems and challenges.

[0003] First, due to the high-speed rotation and air gap between the magnet and the disc rotor, the magnetic pump will experience magnetic induction heating during operation, which will cause the temperature of the pump body to rise significantly. Especially under high temperature or dry running conditions, the heat generated by the rotor is difficult to be effectively transferred through the medium, which causes the temperature of the magnet to rise sharply. This temperature increase will not only affect the magnetic strength of the permanent magnet, but may also destroy the working state of the magnetic coupling, ultimately leading to a decrease in pump performance or even damage. At present, magnetic pumps on the market mainly dissipate heat through heat sinks on the surface, but this method is relatively inefficient and difficult to meet the heat dissipation needs in high temperature environments.

[0004] Secondly, the isolation sleeve in the magnetic pump plays a vital role in the operation of the pump. It effectively isolates the magnetic field and prevents direct contact between the liquid and the external environment by fixing the pressure plate and the sealing ring. However, the existing isolation sleeve design is usually equipped with only a single-layer sealing ring. After long-term operation, the sealing ring may be damaged due to wear or aging. Once the sealing ring is damaged, a gap may appear at the connection between the pressure plate and the isolation sleeve, causing leakage problems. This will not only affect the normal operation of the magnetic pump, but may also pose a threat to the environment and personnel safety. Utility Model Content

On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0023] A magnetic drive pump according to an embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0024] like Figure 1-4 As shown, a magnetic drive pump according to an embodiment of the utility model includes a base 10 , a fixing bracket 20 , a magnetic pump 30 and a heat dissipation assembly 40 .

[0025] The fixing bracket 20 is disposed on the base 10 , the magnetic pump 30 is disposed on the fixing bracket 20 , and the heat dissipation component 40 is disposed on the magnetic pump 30 .

[0026] It should be noted that the fixing bracket 20 described in this embodiment is mounted on the base 10 by bolts, the fixing bracket 20 and the base 10 are perpendicular to each other, and a groove having the same curvature as the outer wall of the magnetic pump 30 is provided on the top wall of the fixing bracket 20. The magnetic pump 30 is mounted on the fixing bracket 20 and thus fixed to the base 10.

[0027] The heat dissipation assembly 40 includes a coolant storage housing 401 , a cooling tank 402 and a through pipe 403 .

[0028] Among them, there are two groups of coolant storage shells 401, and the two groups of coolant storage shells 401 are respectively arranged on the magnetic pump 30, there are multiple groups of cooling grooves 402, and the multiple groups of cooling grooves 402 are respectively opened on the coolant storage shells 401, and the two ends of the through pipe 403 are respectively connected to the two groups of coolant storage shells 401.

[0029] It should be noted that a liquid injection hole is provided on the coolant storage housing 401, and the coolant is injected into the coolant storage housing 401 through the liquid injection hole. The coolant uses cooling oil, cooling water or liquid hydrogen, etc. A heat sink fin is provided in the cooling tank 402, and the heat sink fin absorbs the heat generated by the operation of the magnetic pump 30 and dissipates the heat through the coolant.

[0030] Specifically, the steps to accelerate heat dissipation and strengthen internal sealing when the magnetic drive pump is running are: attach the coolant storage shell 401 to the surface of the magnetic pump 30, inject coolant into the coolant storage shell 401, and add cooling fins in the cooling groove 402 to absorb the heat generated when the magnetic pump 30 is running, and accelerate heat dissipation by absorbing heat through the coolant.

[0031] In one embodiment of the present invention, Figure 2 As shown, both groups of coolant storage shells 401 are arc-shaped cavity shells, and heat-conducting components 404 are evenly arranged on the surface of the coolant storage shells 401.

[0032] It should be noted that the surfaces of the coolant storage housing 401 and the magnetic pump 30 are completely attached together and fixed, ensuring that the attached surfaces overlap to accelerate heat conduction. The heat conducting component 404 is one of a copper sheet, an alloy aluminum sheet or an aluminum foil sheet, which ensures the contact surface and enhances the heat absorption speed.

[0033] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, an isolation assembly 50 and a pressing assembly 60 are also included.

[0034] The isolation assembly 50 is disposed in the magnetic pump 30 , the pressing assembly 60 is disposed in the magnetic pump 30 , and the pressing assembly 60 is connected to the isolation assembly 50 .

[0035] It should be noted that the isolation assembly 50 and the pressing assembly 60 cooperate with each other to be fixed in the magnetic pump 30, and the double-layer seal enhances the isolation sealing performance.

[0036] In one embodiment of the present invention, Figure 3 As shown, the isolation assembly 50 includes an isolation sleeve 501 , a first sealing ring 502 and a second sealing ring 503 .

[0037] The isolation sleeve 501 is disposed in the magnetic pump 30 , and the first sealing ring 502 and the second sealing ring 503 are respectively disposed on the isolation sleeve 501 .

[0038] It should be noted that the isolation sleeve 501 is installed in the magnetic pump 30, and then the first sealing ring 502 is attached to the inner wall of the magnetic pump 30, and the second sealing ring 503 is connected to the first sealing ring 502, and the outer diameter of the second sealing ring 503 is smaller than the outer diameter of the first sealing ring 502.

[0039] In one embodiment of the present invention, Figure 4 As shown, the pressing assembly 60 includes a pressing plate 601 , a positioning screw hole 602 , a first pressing ring 603 and a second pressing ring 604 .

[0040] The pressure plate 601 is disposed in the magnetic pump 30, and there are multiple groups of positioning screw holes 602, which are respectively opened on the pressure plate 601. The first pressure ring 603 and the second pressure ring 604 are respectively disposed in the pressure plate 601, the first pressure ring 603 is pressed on the second sealing ring 503, and the second pressure ring 604 is pressed on the first sealing ring 502.

[0041] It should be noted that the pressure plate 601 is sleeved on the outside of the isolation sleeve 501, and the pressure plate 601 is pressed and fixed in the magnetic pump 30 by a screw matched with the positioning screw hole 602. When the pressure plate 601 is fixedly installed, the second pressure ring 604 is pressed on the first sealing ring 502, and the first pressure ring 603 is pressed on the second sealing ring 503.

[0042] In one embodiment of the present invention, Figure 4 As shown, the bottom outer ring of the first pressure ring 603 and the top inner ring of the second pressure ring 604 form a tapered end surface.

[0043] It should be noted that, when the pressure plate 601 is pressed downward to form the tapered end surface, the first pressure ring 603 presses the second sealing ring 503, and the second sealing ring 503 is squeezed and filled in the tapered end surface, thereby completing the second seal.

[0044] In one embodiment of the present invention, Figure 3 As shown, the first sealing ring 502 and the second sealing ring 503 are an integrated structure, and the first sealing ring 502 and the second sealing ring 503 are both elastic plastic sealing gaskets.

[0045] It should be noted that the first sealing ring 502 and the second sealing ring 503 are deformed by extrusion and fit tightly between the pressure plate 601 and the magnetic pump 30 , forming a double-layer seal, which effectively prevents the problem of liquid leakage inside the magnetic pump 30 .

[0046] The steps of heat dissipation and enhanced sealing of a magnetic drive pump of the present application are: the coolant storage shell 401 is installed on the surface of the magnetic pump 30 and fixedly fitted. When the magnetic pump 30 is running, the coolant in the coolant storage shell 401 absorbs the heat generated by the magnetic pump 30, and the heat dissipation is accelerated by the heat dissipation fins in the cooling groove 402. An isolation assembly 50 is installed in the magnetic pump 30, and the isolation sleeve 501 is limitedly sleeved on the magnetic pump 30, and then the pressure plate 601 is pressed and fixed on the isolation sleeve 501. When the pressure plate 601 is pressed and fixed to the isolation sleeve 501, the second pressure ring 604 is pressed on the first sealing ring 502, and the first pressure ring 603 is pressed on the second sealing ring 503. The second sealing ring 503 is squeezed and filled in the conical end face, thereby completing a double-layer seal. The overall heat dissipation performance of the magnetic pump is enhanced, and at the same time, the sealing is enhanced to prevent internal liquid leakage.

[0047] In summary, a magnetically driven pump according to an embodiment of the utility model improves the heat dissipation performance of the magnetically driven pump during operation, while enhancing the sealing of the isolation sleeve installed in the magnetic pump, thereby meeting the heat dissipation requirements in a high temperature environment and ensuring the normal operation of the magnetic pump.
