Description

Technical Field

[0001] The utility model belongs to the technical field of liquid metal pumps, and in particular relates to a pipeline supporting device for a liquid metal pump. Background Art

[0002] Liquid metal pump is a kind of pump equipment specially used for conveying liquid metal, which has the characteristics of good sealing, high reliability and simple structure. Liquid metal pump realizes the flow and conveying of liquid metal through its internal mechanical or electromagnetic action. The main structure of liquid metal pump includes pump body, impeller, bearing and sealing device, and its working principle involves three basic processes: suction, compression and discharge. Liquid metal electromagnetic pump uses the electromagnetic force generated by the interaction between magnetic field and current in conductive fluid to drive fluid movement. This principle enables liquid metal pump to achieve contactless pumping, thus avoiding the wear and leakage problems that may exist in traditional mechanical pumps. According to the different forms of power supply, liquid metal pumps can be divided into AC pumps and DC pumps. According to the feeding method of current in liquid metal, it can be divided into conductive electromagnetic pumps and inductive electromagnetic pumps. Conductive electromagnetic pumps transmit current directly through the fluid, while inductive electromagnetic pumps generate current inside the fluid through electromagnetic induction. When the liquid metal pump is in use, the pipe connected to the outlet of the liquid metal pump is easily affected by vibration and its own weight, resulting in reduced operating reliability of the liquid metal pump. Therefore, a pipe bracket is required to support it to reduce vibration and prevent the influence of the pipe weight on the pump.

[0003] However, the pipe bracket commonly used in the prior art has a placement surface, and the pipe is placed on it. When the pipe expands and contracts due to high temperature, a huge thermal expansion thrust is generated, thereby increasing the bending moment borne by the pump port; at the same time, the friction between the pipe and the bracket is increased, thereby increasing the axial stress of the pump port, and even causing the pump pipe port to be subjected to excessive external load and unable to continue working.

[0046] Example:

[0047] This embodiment provides a pipeline support device for a liquid metal pump, which is used to solve the technical problem of friction between the pipeline support for a liquid metal pump and the pipeline in the prior art. The pipeline support device for a liquid metal pump includes a support 1, a load-bearing member 2, a connecting member 3, a rolling assembly 4, a limit block 5 and a thrust assembly 6, wherein:

[0048] The bracket 1 is a structural member made of metal material.

[0049] The load-bearing member 2 is placed horizontally on the bracket 1. Optionally, the load-bearing member 2 is a hollow cylinder, and the axis of the hollow cylinder is horizontally arranged, that is, the horizontal plane where the axis of the hollow cylinder is located is parallel to the plane where the top of the bracket 1 is located.

[0050] One end of the connecting member 3 is fixedly installed in the middle of the load-bearing member 2, and the other end of the connecting member 3 extends downward. The connecting member 3 is used to hoist the pipeline 7, that is, the connecting member 3 and the load-bearing member 2 are arranged perpendicular to each other. When using the pipeline support device for the liquid metal pump provided in the embodiment of the utility model, the side wall of the pipeline 7 is fixedly installed on the end of the connecting member 3 extending downward.

[0051] There are two rolling assemblies 4, and both rolling assemblies 4 are installed between the load-bearing member 2 and the bracket 1, and are located at both ends of the load-bearing member 2. In this way, through the setting of the rolling assembly 4, when the pipeline 7 expands due to heat, the connecting member 3 and the load-bearing member 2 are subjected to thermal stress, and drive the load-bearing member 2 and the bracket 1 to move relative to each other, thereby reducing the friction between the load-bearing member 2 and the bracket 1.

[0052] There are two limit blocks 5 , which are arranged on both sides of the load-bearing member 2 and spaced apart from the load-bearing member 2 . Thus, the limit blocks 5 are arranged to limit the distance that the load-bearing member 2 moves in the horizontal direction.

[0053] The thrust assembly 6 is installed between the bracket 1 and the limit block 5 and is located above the load-bearing member 2. In this way, the displacement of the load-bearing member 2 in the vertical direction is limited by the setting of the thrust assembly 6.

[0054] Through the above structure, when using the pipeline support device for liquid metal pump provided by the utility model, the end of the connecting member 3 extending downward is first welded to the outer wall of the pipeline 7 connected to the outlet of the liquid metal pump, and the other end of the connecting member 3 is fixedly connected to the load-bearing member 2 placed on the bracket 1, so that the pipeline 7 is hoisted in the air. During the operation of the liquid metal pump, the temperature of the pipeline 7 gradually increases, the pipeline 7 begins to expand, the connecting member 3 and the load-bearing member 2 are subjected to thermal stress, and a rolling assembly 4 is provided between the load-bearing member 2 and the bracket 1, so that the load-bearing member 2 is displaced on the bracket 1, reducing the axial stress generated by friction at the pump port of the liquid metal pump. By setting the limit blocks 5 installed on both sides of the load-bearing member 2, the distance that the load-bearing member 2 moves in the horizontal direction is limited. At the same time, by setting the thrust assembly 6 located above the load-bearing member 2, the expansion of the load-bearing member 2 is limited. Therefore, by setting the rolling assembly 4, the pipeline support device for liquid metal pump provided by the utility model can move relative to the pipeline 7, thereby reducing the axial stress of the pump port caused by friction, and the practicality is stronger.

[0055] An optional implementation of this embodiment is as follows: the rolling assembly 4 includes a mounting plate 41, a mounting block 42, a first rolling ball 43 and a placement plate 44, wherein:

[0058] The number of the first ball bearings 43 is multiple. A plurality of first mounting grooves adapted to the first ball bearings 43 are formed at the top end of the mounting block 42. The plurality of first ball bearings 43 are respectively rotatably mounted in the plurality of first mounting grooves and protrude from the first mounting grooves.

[0059] The placing plate 44 is placed on the plurality of first ball bearings 43. Through the arrangement of the first ball bearings 43, the friction between the placing plate 44 and the mounting block 42 is reduced, making it easier for the placing plate 44 to move on the mounting block 42. Moreover, the arrangement of the plurality of ball bearings enables the placing plate 44 to be placed more stably.

[0064] The thrust plate 64 is placed on the top ends of the two limiting blocks 5, and the top end of the thrust plate 64 is in contact with the second ball bearings 63. In this way, through the arrangement of the thrust plate 64, when the load-bearing member 2 expands to be in contact with the thrust plate 64, the further expansion of the load-bearing member 2 is restricted. At the same time, when the load-bearing member 2 is in contact with the thrust plate 64, through the arrangement of the second ball bearings 63, when the load-bearing member 2 undergoes displacement, the friction between the thrust plate 64 and the mounting frame 62 is reduced, making it easier for the load-bearing member 2 to move.

[0065] Optionally, it further includes a limiting plate 65. The number of the limiting plates 65 is two. The two limiting plates 65 are respectively fixedly mounted on the top ends of the two limiting blocks 5. The thrust plate 64 is located between the two limiting plates 65, and the thrust plate 64 is spaced from the two limiting plates 65. In this way, through the arrangement of the two limiting plates 65, the moving distance of the thrust plate 64 is restricted.

[0066] An optional implementation of this embodiment is as follows: it also includes a heating component, which is installed in the load-bearing member 2 and the connecting member 3. The heating component is used to heat the load-bearing member 2 and the connecting member 3.

[0070] The second tube 32 is detachably mounted on the other end of the first tube 31 . Thus, the detachably mounted second tube 32 makes it easier to inspect the heating wires installed in the connecting member 3 and the load-bearing member 2 .
