Description

Technical Field

[0001] The utility model belongs to the technical field of vertical multistage pumps, and in particular relates to a vertical multistage pump quick disassembly and assembly device. Background Art

[0002] Vertical multistage pumps are widely used. Their structural features are that the bearing chamber, matching motor and pump body are assembled in one body. Because the overall length or height is too long and there is no quick disassembly device, they can only be transported and hoisted as a whole, or all parts are forced to be removed from one side of the equipment. This brings defects. First, it is not convenient for transportation, installation and fault repair, and it brings certain safety hazards during installation, repair and fault judgment. Second, the overall maintenance workload increases several times, and the disassembly and assembly technology is very high. The disassembly and assembly process is very easy to cause damage to major components such as mechanical seals and bearings, resulting in increased maintenance costs.

[0003] On the one hand, when the original structure needs to dismantle and inspect the upper motor, bearing chamber or lower water pump, it must be dismantled step by step from one side of the equipment to achieve comprehensive removal of equipment parts to check for hidden dangers or replace damaged parts, which increases the difficulty of maintenance and unnecessary workload, resulting in a large waste of human resources. In addition, because the overall length of the equipment is too long, special brackets or lifting tools need to be made to achieve smooth disassembly and assembly of the equipment. On the other hand, because the overall length of the equipment is too long, it is difficult to transport and lift the equipment, increasing the transportation and loading and unloading costs, and also bringing greater safety hazards. Therefore, a vertical multi-stage pump quick disassembly and assembly device is proposed. Utility Model Content

[0015] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0017] Embodiment 1, as Figure 1As shown, a vertical multi-stage pump quick disassembly and assembly device includes a coupling 1, which is used to connect the external pump body and the motor to transmit power and realize the rotation of the pump body. The coupling 1 is provided with connecting short pipes 2 on both sides. The connecting short pipes 2 facilitate the connection of the coupling 1 with other components and play a connecting and fixing role. An auxiliary hand hole 5 is provided in the middle of the connecting short pipe 2. The auxiliary hand hole 5 is transversely arranged on the connecting short pipe 2 to facilitate the operator to disassemble and assemble and improve the disassembly and assembly efficiency. A blind plate 7 is provided outside the auxiliary hand hole 5. The blind plate 7 is used to close the auxiliary hand hole 5 to prevent debris from entering and protect the interior from pollution.

[0018] The following is a detailed description of the design of the above key components:

[0019] The outer end of the connecting short pipe 2 is provided with a fixing seat 3. The fixing seat 3 is mainly used to enhance the stability of the connecting short pipe 2 in connecting the external pump body or other components. The fixing seat 3 can ensure that the connecting short pipe 2 will not loosen or shift, avoid shifting or misalignment during the disassembly and assembly process, thereby ensuring the firmness and safety of the connection.

[0020] A through hole 4 is vertically arranged in the fixing seat 3. The through hole 4 is used for connecting and fixing the fixing seat 3 with external components.

[0021] A connecting flange 6 is provided on the outside of the auxiliary hand hole 5, and a blind plate 7 is provided on the connecting flange 6. The connecting flange 6 is convenient for connecting the auxiliary hand hole 5 and protecting the connecting parts on the outside of the auxiliary hand hole 5. The connecting flange 6 can make it easier for the operator to disassemble and assemble, thereby improving the operating efficiency. The blind plate 7 is provided on the connecting flange 6, and is used to close the auxiliary hand hole 5 when not in use, so as to prevent dust, debris, etc. from entering the inside of the auxiliary hand hole 5, protect the connecting parts from pollution, and extend the service life. At the same time, the blind plate 7 can also play a role in aesthetics, making the entire connection structure look neater and more complete.

[0022] A vertical multistage pump quick disassembly and assembly device utilizes the structural characteristics of such equipment as vertical multistage pumps. Without affecting the overall strength and tightness of the equipment, an auxiliary hand hole 5 for maintenance is added to the connecting short pipe 2 outside the coupling 1, and a blind plate 7 is installed as an auxiliary maintenance hole. When the water pump or bearing chamber needs to be disassembled, the coupling 1 locking bolt and the auxiliary sleeve can be quickly disassembled, and the pump body and the upper bearing seat and the motor can be disassembled, which is convenient for transportation, hoisting, reverse transportation, maintenance, and fault judgment. Through use in actual production, the effect is good and it meets the needs of on-site maintenance and transportation.
