Description

Technical Field

[0001] The utility model relates to the technical field of submersible electric pumps, in particular to a high-temperature resistant dry-type submersible electric pump. Background Art

[0002] According to domestic industry standards, the motors used in submersible electric pumps are of three types: dry, oil-filled and wet. The motors in dry submersible electric pumps are all sealed. During operation, the heat generated by the motors of dry submersible electric pumps is slowly dissipated and has low heat resistance.

[0003] A high-temperature resistant dry-type submersible electric pump currently in use has been found through search, for example, in a Chinese patent document with an authorization publication number of CN217761468U, which discloses a high-temperature resistant submersible pump, including a submersible pump, a fixed base is arranged at the lower end of the submersible pump; a stabilizing frame, the stabilizing frame includes a support plate at the end, the lower end of the submersible pump is fixedly connected to the upper end of the support plate, and a ferrule is arranged at the upper end of the stabilizing frame, and the ferrule is clamped and fastened to the outside of the submersible pump, and the beneficial effects are: the utility model can conveniently and quickly install the submersible pump on the stabilizing frame by arranging the stabilizing frame, and the stabilizing frame can increase the stability of the submersible pump when lowered into the water, improve the stability of the submersible pump at the bottom of the water, and avoid the submersible pump being overturned by the impact of the water flow, affecting the use effect, and the stabilizing frame is convenient to install and disassemble, which is convenient for subsequent inspection and maintenance of the submersible pump, and the stabilizing frame can support the connecting pipe, increase the stability of the connection between the pipe and the submersible pump, and avoid deformation of the pipe connection that affects the use effect.

[0004] Although the above patents solve the problems in the above-mentioned background technology, there are still the following shortcomings: 1. The shell cover of the submersible pump is not easy to disassemble. Therefore, during maintenance, the maintenance personnel cannot quickly separate the shell cover and the pump body. This separation method is time-consuming and labor-intensive, which in turn affects the maintenance progress of the submersible pump and reduces the practical effect of the submersible pump; 2.

[0030] In this embodiment, the copper heat sink 203 is mainly used to quickly diffuse the heat generated by the drive motor, and the micro-circulation waterproof pump 202 is mainly used to extract cooling water from the copper cooling box 201, which then flows along the guide pipe 204 and flows back to the copper cooling box 201. During the flow, the cooling water can guide the heat inside the pump cover 2, thereby achieving the effect of cooling the inside of the pump cover 2.

[0031] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The convenient disassembly mechanism 3 includes a sealing groove 301, a fastening block 302 and a sealing mounting block 303. The sealing groove 301 is provided on the top surface of the pump body 1, and a supporting spring 304 is provided inside the sealing groove. A sealing ring block 305 is fixedly installed on the top of the supporting spring 304. The fastening block 302 is fixedly installed on the outer surface of the pump body 1, and a plug rod 306 is embedded and installed on the side away from the pump body 1. A compression spring 307 is provided on the outer side of the plug rod 306. A pull ring 308 is fixedly installed on the end of the plug rod 306 away from the fastening block 302. The sealing mounting block 303 is fixedly installed on the bottom surface of the pump cover 2, and a plug hole 309 is provided on the outer surface of the plug rod 306.

[0032] Specifically, the cross-sectional shape of the sealing installation block 303 matches the sealing groove 301, and its outer surface contacts the inner wall of the sealing groove 301, the support spring 304 is equidistantly distributed in a ring shape about the inner wall of the bottom end of the sealing groove 301, the outer surface of the sealing ring block 305 is slidably fitted with the inner wall of the sealing groove 301, the end of the compression spring 307 away from the fastening block 302 is connected to the side surface of the pull ring 308, the end of the insertion rod 306 close to the fastening block 302 is movable and penetrates the rear side surface of the fastening block 302 and the rear side surface of the pump body 1 in turn and extends to the inside of the sealing groove 301, and it is correspondingly arranged with the plug hole 309 and plugged in and matched;

[0033] In the present embodiment, the sealing groove 301 is mainly used to contact the sealing mounting block 303, and the supporting spring 304 is mainly used to elastically support the sealing ring block 305, so that the sealing ring block 305 is in sealing contact with the sealing mounting block 303, thereby realizing the sealing setting between the pump cover 2 and the pump body 1, and the compression spring 307 is mainly used to drive the insertion rod 306 to fit with the socket 309, and the pull ring 308 is mainly used to drive the insertion rod 306 to disengage from the socket 309 and stretch the compression spring 307, thereby achieving the effect of quickly disassembling the pump cover 2 and meeting the needs of users.

[0034] The working process of the utility model is as follows: when using a high-temperature resistant dry-type submersible electric pump, the submersible pump is moved to the desired position and ensures that the bottom surface of the support seat 102 is in contact with the surface of the placement point, and then the operation can be carried out. During the operation, the copper heat sink 203 can quickly discharge the heat generated by the operation of the drive motor. At this time, the micro-circulation waterproof pump 202 is started. Under the action of the micro-circulation waterproof pump 202, the cooling water in the copper cooling box 201 moves along the guide pipe 204 to the inside of the pump cover 2, and finally flows back to the copper cooling box 201. During the flow of the cooling water, the heat inside the pump cover 2 can be radiated. The amount is adsorbed, so that the temperature inside the pump cover 2 can be quickly reduced, thereby improving the heat resistance of the submersible pump and facilitating the long-term use of the submersible pump. Furthermore, when the submersible pump needs to be repaired, an external force is applied to the pull ring 308, and the pull ring 308 drives the insertion rod 306 to move and stretch the compression spring 307 until the insertion rod 306 is completely separated from the insertion hole 309. At the same time, the support spring 304 in the compressed state gradually stretches and moves the sealing ring block 305 upward, and then applies an upward force to the pump cover 2, so that the pump cover 2 and the pump body 1 can be disassembled, which is convenient for the subsequent maintenance of the maintenance personnel and improves the practical effect of the submersible pump.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
