Description

Technical Field

[0001] This utility model relates to the technical field of canned pumps, specifically to a novel RB end cap temperature measuring hole structure for a canned pump with a bearing temperature transmitter. Background Technology

[0002] In recent years, with the increasing awareness of safety and environmental protection, more and more attention has been paid to real-time monitoring of product performance. As a product that transports high-risk media, the failure of a canned motor pump can affect the environment and the health and safety of personnel. Therefore, more and more products are equipped with bearing temperature transmitters to monitor bearing temperature in real time and solve problems in time. However, when the installation space of the bearing temperature transmitter is limited, how to open the temperature measuring hole without interfering with other components becomes a problem. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a novel RB end cap temperature measuring hole structure.

[0004] The technical solution adopted by this utility model to achieve the above objectives is as follows:

[0005] A novel RB end cap temperature measuring hole structure includes an RB end cap, which comprises a cylindrical body and a flange connected in sequence. The cylindrical body is inserted into the stator rear flange. A sealing gasket is installed between one end of the flange connecting the cylindrical body and the stator rear flange. The axial center hole of the flange is connected to a union joint. One end of the flange connecting the cylindrical body has an axially open connecting hole, and the other end of the flange has an axially open temperature measuring hole. One end of the temperature measuring hole is connected to a bearing temperature transmitter, and the other end of the temperature measuring hole communicates with the inner cavity of the cylindrical body through the connecting hole. Both the connecting hole and the temperature measuring hole are eccentric holes, and the distance between the axis of the connecting hole and the axis of the flange center hole is less than the distance between the axis of the temperature measuring hole and the axis of the flange center hole.

[0006] The distance between the axis of the connecting hole and the axis of the temperature measuring hole is less than the sum of their radii.

[0007] The distance between the axis of the connecting hole and the axis of the cylinder is greater than the radius of the cylinder.

[0008] The cylinder body is welded to the flange as a single unit.

[0009] The features of this utility model are: simple structure, convenient operation, and the ability to simultaneously ensure the wrench space of the live joint and the pressing space of the sealing gasket in the case of limited space. Attached Figure Description

[0012] Among them: 1. RB end cap 11. Cylinder 111. Inner cavity 12. Flange 121. Center hole 122. Connecting hole 123. Temperature measuring hole 2. Stator rear flange 3. Sealing gasket 4. Union joint 5. Bearing temperature transmitter. Detailed Implementation

[0013] like Figure 1 , 2 As shown, this utility model is a novel RB end cap temperature measuring hole structure, including an RB end cap 1. The RB end cap 1 includes a cylindrical body 11 and a flange 12 connected in sequence and welded together. The cylindrical body 11 is inserted into the stator rear flange 2. A sealing gasket 3 is installed between one end of the flange 12 connecting the cylindrical body 11 and the stator rear flange 2. The axial center hole 121 of the flange 12 is connected to a union joint 4. One end of the flange 12 connecting the cylindrical body 11 has an axially open connecting hole 122, and the other end of the flange 12 has an axially open temperature measuring hole 123. One end of the temperature measuring hole 123 is connected to the bearing temperature transmitter 5, and the other end of the temperature measuring hole 123 is connected to the inner cavity 111 of the cylinder 11 through the connecting hole 122. Both the connecting hole 122 and the temperature measuring hole 123 are eccentric holes. The distance between the axis of the connecting hole 122 and the axis of the center hole 121 of the flange 12 is less than the distance between the axis of the temperature measuring hole 123 and the axis of the center hole 121 of the flange 12. The distance between the axis of the connecting hole 122 and the axis of the temperature measuring hole 123 is less than the sum of their radii. The distance between the axis of the connecting hole 122 and the axis of the cylinder 11 is greater than the radius of the cylinder 11.

[0014] During processing, a connecting hole 122 and a temperature measuring hole 123 are first machined on the flange 12, and then welded to the cylinder 11 to form the RB end cover 1. This ensures that the internal connecting hole 122 is closer to the center of the RB end cover 1, so as not to damage the pressing surface of the sealing gasket 3 and ensure the sealing performance. On the other hand, the external temperature measuring hole 123 is farther from the center of the RB end cover 1, and there is enough wrench space between it and the union joint 4 for easy operation.

[0015] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
