Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving pumps, and particularly to a high-efficiency centrifugal energy-saving pump for a gas-liquid separator. Background Art

[0002] In the modern industrial field, a centrifugal pump is used when a gas-liquid separator is working. The sealing performance and operating efficiency of the centrifugal pump have a crucial impact on the system energy consumption and stability. However, the existing centrifugal pumps for gas-liquid separators mostly adopt traditional mechanical sealing methods, relying on the spring pre-tightening force to maintain the fitting of the moving ring and the static ring. As key sealing components, the moving ring and the static ring are in continuous contact and friction during the working process, resulting in wear of the sealing surface, thereby reducing the sealing performance, causing medium leakage, and affecting the pumping efficiency. At the same time, the heat generated by the friction causes the temperature of the sealing components to rise sharply, which not only accelerates the material aging, but also destroys the fitting degree of the sealing surface due to thermal deformation, further increasing the leakage risk. Summary of the Invention

[0003] The purpose of the present invention is to provide a high-efficiency centrifugal energy-saving pump for a gas-liquid separator to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A high-efficiency centrifugal energy-saving pump for a gas-liquid separator, including a pump body and a fixed shell installed on the pump body, further including: A first connecting shaft, arranged on the fixed shell, on which a positioning ring and a moving ring body are coaxially arranged, and a connecting spring is arranged between the positioning ring and the moving ring body; A static ring body, fixed in the fixed shell and sealingly matched with the moving ring body; An oil supply mechanism, arranged between the positioning ring and the moving ring body, for extruding lubricating oil; A heat conduction mechanism, arranged on the first connecting shaft, for cooling the moving ring body through the first connecting shaft; When the moving ring body and the static ring body are worn, the connecting spring drives the moving ring body to axially move to compensate for the wear gap, and synchronously drives the oil supply mechanism to extrude lubricating oil to the mating surface of the static ring body and the moving ring body; The heat conduction mechanism includes a conical cavity opened inside the first connecting shaft, a cooling circulation member communicating with the conical cavity, and a heat dissipation member for dissipating heat of the coolant.

[0005] Preferably, the cooling circulation member includes a plurality of connecting ducts communicating with the conical cavity. One end of each of the plurality of connecting ducts away from the conical cavity is communicated with a cooling storage tube, and a heat conduction ring is commonly connected to the plurality of cooling storage tubes.

[0006] Preferably, one end of the connecting duct away from the conical cavity extends obliquely away from the axis of the first connecting shaft, and the plurality of cooling storage tubes are arranged in an annular array on the heat conduction ring.

[0007] Preferably, the heat dissipation member includes a heat dissipation plate fixedly installed inside the heat conduction ring and a support connecting rod rotatably arranged inside the heat conduction ring. A fan blade is arranged on the support connecting rod, and a driving part is arranged on the support connecting rod.

[0008] Preferably, the driving part includes a driving gear fixedly installed at one end of the support connecting rod. A fixed gear ring is meshed with the driving gear, and a support connecting plate is fixedly connected to the fixed gear ring through a connecting fixing plate.

[0009] Preferably, a plurality of the cooling storage tubes rotate synchronously with the first connecting shaft. When the cooling storage tube rotates to the upper side of the first connecting shaft, the cooling water inside it flows into the conical cavity through the connecting conduit. When the cooling storage tube rotates to the lower side of the first connecting shaft, the cooling water in the conical cavity flows into the cooling storage tube through the connecting conduit.

[0010] Preferably, a support frame plate is connected to the heat conduction ring. One end of the support frame plate far from the heat conduction ring is fixedly connected to a second connecting shaft. The second connecting shaft is rotatably arranged on the support connecting plate, and a support base is fixedly connected to the lower end of the support connecting plate.

[0011] Preferably, the oil supply mechanism includes a fixed sliding plate fixedly installed on the positioning ring and an internal moving groove opened inside the moving ring body. A sliding clamping plate is arranged on the fixed sliding plate. One end of the sliding clamping plate is fixedly connected to a connecting folding rod. The connecting folding rod slides into the internal moving groove, and a fixed column is fixedly arranged in the internal moving groove.

[0012] Preferably, a piston moving plate is slidably connected inside the fixed column. One end of the connecting folding rod far from the sliding clamping plate slides into the fixed column and is fixedly connected to the piston moving plate. An adding pipe and an oil outlet connecting pipe are arranged on the fixed column. One end of the oil outlet connecting pipe far from the fixed column extends out of the annular groove on the moving ring body.

[0013] Preferably, when the moving ring body axially moves, the movement of the sliding clamping plate is restricted by the fixed sliding plate, and the moving ring body drives the fixed column to move, so that the piston moving plate can press the lubricating oil in the oil storage cavity into the mating surface of the stationary ring body and the moving ring body through the oil outlet connecting pipe.

[0014] Preferably, one end of the first connecting shaft is fixedly connected to a middle connecting rod. One end of the middle connecting rod is fixedly connected to a second connecting shaft. One end of the second connecting shaft is connected to a driving motor through a coupling.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By providing an oil supply mechanism, when the moving ring body and the stationary ring body are worn due to friction, the connecting spring can drive the axial movement of the moving ring body to compensate for the wear gap. At the same time, the movement of the moving ring body will drive the operation of the oil supply mechanism. The fixed slide plate restricts the movement of the sliding clamping plate, enabling the lubricating oil in the fixed column to be pressed into the mating surface of the stationary ring body and the moving ring body through the oil outlet connecting pipe. This can significantly slow down the wear of the sealing surface, extend the service life of the moving ring body and the stationary ring body, reduce the risk of medium leakage, and improve the gas-liquid separation and pumping efficiency.

[0016] 2. By providing a heat conduction mechanism, when the first connecting shaft rotates, it drives the cooling storage pipe to rotate synchronously. Through the inclined connecting conduit, the dynamic flow of cooling water between the conical cavity and the cooling storage pipe can be realized, continuously cooling the moving ring body. At the same time, the heat conduction ring and the heat dissipation plate cooperate to support the fan blades on the connecting rod. Under the meshing action of the driving gear and the fixed gear ring, the fan blades can rotate while revolving with the heat conduction ring, greatly strengthening the air flow, accelerating the heat dissipation, more efficiently reducing the temperature of the moving ring body, slowing down the thermal deformation and material aging of the sealing components caused by high temperature, and ensuring the stability of the sealing performance.

[0017] 3. Through the coordinated operation of the oil supply mechanism and the heat conduction mechanism, the centrifugal energy-saving pump realizes the organic combination of the functions of seal compensation, lubrication, and cooling. On the one hand, it reduces the medium leakage and equipment failure shutdown time caused by seal failure. On the other hand, it reduces the additional energy consumption brought by friction loss and poor heat dissipation, reduces the maintenance cost, and saves energy. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 to 14, the present invention provides a technical solution: a high-efficiency centrifugal energy-saving pump for a gas-liquid separator, including a pump body 3 and a fixed shell 31 installed on the pump body 3, and further including: a first connecting shaft 13, arranged on the fixed shell 31, on which a positioning ring 7 and a dynamic ring body 11 are coaxially arranged, the positioning ring 7 is fixedly connected to the first connecting shaft 13, and a connecting spring 12 is arranged between the positioning ring 7 and the dynamic ring body 11; a static ring body 10, fixed in the fixed shell 31 and in sealing cooperation with the dynamic ring body 11; an oil supply mechanism 9, arranged between the positioning ring 7 and the dynamic ring body 11, for extruding lubricating oil; a heat conduction mechanism 6, arranged on the first connecting shaft 13, for cooling the dynamic ring body 11 through the first connecting shaft 13; when the dynamic ring body 11 and the static ring body 10 are worn, the connecting spring 12 drives the dynamic ring body 11 to axially move to compensate for the wear gap, and simultaneously drives the oil supply mechanism 9 to extrude lubricating oil to the mating surface of the static ring body 10 and the dynamic ring body 11; the heat conduction mechanism 6 includes a tapered cavity 61 opened inside the first connecting shaft 13, a cooling circulation member communicating with the tapered cavity 61, and a heat dissipation member for dissipating heat from the coolant. By providing the oil supply mechanism 9, when the dynamic ring body 11 and the static ring body 10 are worn due to friction, the connecting spring 12 can drive the dynamic ring body 11 to axially move to compensate for the wear gap. At the same time, the movement of the dynamic ring body 11 will drive the oil supply mechanism 9 to operate. The fixed slide plate 91 restricts the movement of the sliding clamping plate 92, and the lubricating oil in the fixed column 95 can be pressed into the mating surface of the static ring body 10 and the dynamic ring body 11 through the oil outlet connecting pipe 98, which can significantly slow down the wear of the sealing surface, extend the service life of the dynamic ring body 11 and the static ring body 10, reduce the risk of medium leakage, and improve the gas-liquid separation and pumping efficiency. By providing the heat conduction mechanism 6, when the first connecting shaft 13 rotates, it drives the cooling storage pipe 63 to rotate synchronously. Through the inclined connecting conduit 62, the dynamic flow of cooling water between the tapered cavity 61 and the cooling storage pipe 63 can be realized, and the dynamic ring body 11 can be continuously cooled. At the same time, the heat conduction ring 64 and the heat dissipation plate 65 cooperate with the fan blades 68 on the support connecting rod 67. Under the meshing action of the driving gear 69 and the fixed tooth ring 610, the fan blades 68 can rotate while revolving with the heat conduction ring 64, greatly strengthening the air flow, accelerating heat dissipation, and more efficiently reducing the temperature of the dynamic ring body 11, slowing down the thermal deformation and material aging of the sealing components caused by high temperature, and ensuring the stable sealing performance. Through the coordinated work of the oil supply mechanism 9 and the heat conduction mechanism 6, the centrifugal energy-saving pump realizes the organic combination of sealing compensation, lubrication and cooling functions. On the one hand, it reduces the medium leakage and equipment failure shutdown time caused by seal failure. On the other hand, it reduces the additional energy consumption caused by friction loss and poor heat dissipation, reduces the maintenance cost, and saves energy.

[0035] As Figures 9 to 12As shown in the figure, the cooling circulation component includes a plurality of connecting conduits 62 communicating with the conical cavity 61. One end of each of the plurality of connecting conduits 62 far from the conical cavity 61 is communicated with a cooling storage tube 63. A heat conduction ring 64 is commonly connected to the plurality of cooling storage tubes 63. One end of the connecting conduit 62 far from the conical cavity 61 extends obliquely away from the axis of the first connecting shaft 13. The plurality of cooling storage tubes 63 are arranged in a circular array on the heat conduction ring 64. When the cooling storage tube 63 rotates to the upper side of the first connecting shaft 13, the cooling water therein flows into the conical cavity 61 through the obliquely arranged connecting conduit 62. The conical cavity 61 is opened at a position in the first connecting shaft 13 close to the moving ring body 11 to realize cooling of the moving ring body 11. When the cooling storage tube 63 rotates to the lower side, the cooling water in the conical cavity 61 flows into the cooling storage tube 63 through the connecting conduit 62, and the heat of the cooling water in the cooling storage tube 63 can be conducted to the heat conduction ring 64.

[0036] As Figure 13 shown in the figure, the heat dissipation component includes a heat dissipation plate 65 fixedly installed inside the heat conduction ring 64 and a support connecting rod 67 rotatably arranged inside the heat conduction ring 64. Fan blades 68 are arranged on the support connecting rod 67. A driving part is arranged on the support connecting rod 67. The driving part includes a driving gear 69 fixedly installed at one end of the support connecting rod 67. A fixed gear ring 610 is engaged with the driving gear 69. A support connecting plate 16 is fixedly connected to the fixed gear ring 610 through a connecting fixing plate 611. When the heat conduction ring 64 rotates, the plurality of support connecting rods 67 follow the heat conduction ring 64 to achieve revolution. At the same time, due to the engagement of the driving gear 69 and the fixed gear ring 610 and the fixed immobility of the fixed gear ring 610, the support connecting rod 67 rotates during the revolution process, driving the fan blades 68 to rotate at a high speed, accelerating the air flow, greatly strengthening the heat dissipation effect, and significantly improving the heat dissipation speed of the heat dissipation plate 65 and the heat dissipation efficiency of the cooling water.

[0037] As Figures 11 to 14 shown in the figure, the plurality of cooling storage tubes 63 rotate synchronously with the first connecting shaft 13. When the cooling storage tube 63 rotates to the upper side of the first connecting shaft 13, the cooling water therein flows into the conical cavity 61 through the connecting conduit 62. When the cooling storage tube 63 rotates to the lower side of the first connecting shaft 13, the cooling water in the conical cavity 61 flows into the cooling storage tube 63 through the connecting conduit 62. A support frame plate 66 is connected to the heat conduction ring 64. One end of the support frame plate 66 far from the heat conduction ring 64 is fixedly connected to a second connecting shaft 15. The second connecting shaft 15 is rotatably arranged on the support connecting plate 16. The lower end of the support connecting plate 16 is fixedly connected to a support base 1.

[0038] As Figures 3 to 7As shown, the oil supply mechanism 9 includes a fixed slide plate 91 fixedly installed on the positioning ring 7 and an internal transfer groove 94 opened inside the moving ring body 11. A sliding clamping plate 92 is arranged on the fixed slide plate 91. One end of the sliding clamping plate 92 is fixedly connected with a connecting folding rod 93. The connecting folding rod 93 slides into the internal transfer groove 94. A fixed column 95 is fixedly arranged in the internal transfer groove 94. A piston moving plate 96 is slidably connected in the fixed column 95. One end of the connecting folding rod 93 away from the sliding clamping plate 92 slides into the fixed column 95 and is fixedly connected with the piston moving plate 96. An adding pipe 97 and an oil outlet connecting pipe 98 are arranged on the fixed column 95. A one-way inlet valve is arranged on the adding pipe 97. One end of the oil outlet connecting pipe 98 away from the fixed column 95 extends out of the annular groove 18 on the driven ring body 11. A one-way outlet valve is arranged on the oil outlet connecting pipe 98. When the moving ring body 11 axially moves, the movement of the sliding clamping plate 92 is restricted by the fixed slide plate 91. The moving ring body 11 drives the fixed column 95 to move, and the piston moving plate 96 can press the lubricating oil in the oil storage cavity into the mating surface of the stationary ring body 10 and the moving ring body 11 through the oil outlet connecting pipe 98. The stationary ring body 10 and the moving ring body 11 are worn due to friction. The connecting spring 12 immediately drives the moving ring body 11 to axially move to compensate for the wear gap. During this process, the moving ring body 11 drives the oil supply mechanism 9 to operate. The moving ring body 11 drives the fixed column 95 to move. The fixed slide plate 91 restricts the movement of the sliding clamping plate 92, so that the connecting folding rod 93 does not move with the moving ring body 11. At the same time, the piston moving plate 96 maintains a stable state. When the fixed column 95 moves, a relative movement is generated between the piston moving plate 96 and the fixed column 95, and then the piston moving plate 96 presses the lubricating oil in the fixed column 95 into the mating surface of the stationary ring body 10 and the moving ring body 11 through the oil outlet connecting pipe 98 to achieve lubrication and extend the service life of the stationary ring body 10 and the moving ring body 11.

[0039] As Figure 3 As shown, one end of the first connecting shaft 13 is fixedly connected with a middle connecting rod 14. One end of the middle connecting rod 14 is fixedly connected with a second connecting shaft 15. One end of the second connecting shaft 15 is connected with a driving motor 2 through a coupling 4. A stationary ring seat 8 is fixedly arranged in the fixed housing 31. The stationary ring body 10 is fixedly installed on the stationary ring seat 8.

[0040] In actual use, the drive motor 2 drives the second connecting shaft 15, the middle connecting rod 14, and the first connecting shaft 13 to rotate through the coupling 4, thereby rotating the impeller 5 in the pump body 3 to achieve the pumping function; during operation, the dynamic ring body 11 and the static ring body 10 are worn due to friction, and the connecting spring 12 immediately drives the dynamic ring body 11 to axially move to compensate for the wear gap. During this process, the dynamic ring body 11 drives the oil supply mechanism 9 to operate. The dynamic ring body 11 drives the fixed column 95 to move. The fixed slide plate 91 restricts the movement of the sliding clamping plate 92, so that the connecting folding rod 93 does not move with the dynamic ring body 11. At the same time, the piston moving plate 96 remains in a stable state. When the fixed column 95 moves, a relative movement occurs between the piston moving plate 96 and the fixed column 95. Furthermore, the piston moving plate 96 presses the lubricating oil in the fixed column 95 into the mating surface of the static ring body 10 and the dynamic ring body 11 through the oil outlet connecting pipe 98 to achieve lubrication, extending the service life of the static ring body 10 and the dynamic ring body 11; at the same time, the rotation of the first connecting shaft 13 drives the cooling storage pipe 63 to rotate synchronously through the middle connecting rod 14, the connecting frame plate 17, and the heat conduction ring 64. When the cooling storage pipe 63 rotates to the upper side of the first connecting shaft 13, the cooling water in it flows into the conical cavity 61 through the inclined connecting conduit 62. The conical cavity 61 is opened at a position in the first connecting shaft 13 close to the dynamic ring body 11 to cool the dynamic ring body 11; when the cooling storage pipe 63 rotates to the lower side, the cooling water in the conical cavity 61 flows into the cooling storage pipe 63 through the connecting conduit 62 again. The heat of the cooling water in the cooling storage pipe 63 can be conducted to the heat conduction ring 64, and the heat conduction ring 64 transfers the heat to the heat dissipation plate 65. When the heat conduction ring 64 rotates, the multiple support connecting rods 67 follow the heat conduction ring 64 to achieve revolution. At the same time, since the driving gear 69 meshes with the fixed gear ring 610 and the fixed gear ring 610 is fixed, the support connecting rods 67 rotate during revolution, driving the fan blades 68 to rotate at high speed, accelerating air flow, greatly strengthening the heat dissipation effect, significantly improving the heat dissipation speed of the heat dissipation plate 65 and the heat dissipation efficiency of the cooling water, ensuring that the dynamic ring body 11 is always at a suitable working temperature, further extending its service life, and ensuring the long-term stable and efficient operation of the high-efficiency centrifugal energy-saving pump for the gas-liquid separator.
