Description

A dismantling tool for the sealing sleeve of the outlet section of a centrifugal pump

technical field

The utility model relates to a dismantling tool for a centrifugal pump, in particular to a dismantling tool for a sealing sleeve of a water outlet section of a centrifugal pump. the

Background technique

In the centrifugal pump, the pump shaft at the water outlet section is provided with a sealing sleeve, which is used to support the pump shaft and ensure that the water in the water outlet section will not enter the motor along the shaft hole. Due to the rotating friction and wear between the sealing sleeve and the pump shaft, it is a vulnerable part and often needs to be replaced. At the same time, since the sealing sleeve needs to play a sealing role, the cooperation between the sealing sleeve and the body of the water outlet section is very tight. Like this, when dismantling sealing sleeve, very inconvenient, dismantling by manpower generally needs 2 hours effect, and generally needs two workers to cooperate and just can it be dismantled. the

Utility model content

Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the utility model is: how to provide a convenient disassembly, time-saving and labor-saving removal tool for the sealing sleeve of the water outlet section of the centrifugal pump. the

In order to solve the problems of the technologies described above, the following technical solutions are adopted in the utility model:

A tool for dismantling the sealing sleeve of the outlet section of a centrifugal pump, which is characterized in that it includes a lower pressure plate, a jack located above the lower pressure plate (the description of the orientation in this scheme is based on the working state), and a plug is arranged above the jack, and the upper end of the plug is It has a circular platform that can be inserted into the sealing sleeve and positioned at the lower end of the sealing sleeve, and there are bolt holes on the circular platform; it also includes an upper pressing plate, the lower end of the upper pressing plate has a second circular platform that can be inserted and positioned at the upper end of the sealing sleeve, and the upper pressing plate also has a The lower through hole; also includes a fastening bolt, the fastening bolt can pass through the through hole on the upper platen and screw into the bolt hole of the plug so that the upper platen and the plug are pressed on the upper and lower ends of the sealing sleeve.

In the disassembly tooling of the utility model, when in use, the upper and lower ends of the sealing sleeve are first fastened with the plug, the fastening bolt and the upper pressing plate to make it integrated, and then the lower pressing plate is fixed on the lower end of the sealing sleeve by the auxiliary tool screw , and then use a jack to push between the lower pressing plate and the plug, start the jack, and the sealing sleeve can be connected with the plug and the upper pressing plate to push out the water outlet section of the centrifugal pump conveniently and quickly. Among them, due to the use of jacks to push out, the required disassembly time is greatly reduced, and it only takes 5-10 minutes to disassemble it, and only one person can disassemble it. It saves a lot of manpower and material resources for the company, and saves a lot of time for the product delivery cycle. the

To sum up, the disassembly tooling of the present utility model can conveniently and quickly disassemble the sealing sleeve from the water outlet section of the centrifugal pump during use, and has the characteristics of convenient disassembly, time-saving and labor-saving. the

Description of drawings

Fig. 1 is the structural representation when the utility model is used. the

Detailed ways

The structure and advantages of the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. the

For specific implementation, see Figure 1 for the structure of the utility model, a tool for dismantling the sealing sleeve of the outlet section of a centrifugal pump, including a lower pressure plate 1, a jack located above the lower pressure plate 1 (the description of the orientation in this scheme is based on the working state) 2. A plug 3 is arranged above the jack 2, and the upper end of the plug 3 has a round table that can be inserted into the sealing sleeve 4 and positioned at the lower end of the sealing sleeve 4. The round table is provided with bolt holes; it also includes an upper pressing plate 5, and the lower end of the upper pressing plate 5 has a It can be inserted into and positioned on the second round platform at the upper end of the sealing sleeve 4, and the upper pressing plate 5 also has a downward through hole; it also includes a fastening bolt 7, which can pass through the through hole on the upper pressing plate 5 and Screw into the bolt hole of the plug 3 to make the upper pressing plate 5 and the plug 3 be compressed on the upper and lower ends of the sealing sleeve 4 . the

As shown in Figure 1, when this disassembly tool is used, some screw rods 8 need to be used. The upper ends of the screw rods 8 are screwed into the assembly screw holes on the lower end face of the centrifugal pump outlet section 6, and the lower ends pass through the through holes arranged on the lower pressure plate 1. to fix. Then install the jack 2 on the lower platen 1, fix the upper platen 5 and the plug 3 to the upper and lower ends of the sealing sleeve 4 to be disassembled through the fastening bolts 7, then put the upper end of the jack 2 against the lower end of the plug 3, and start the jack 2 Pushing up, the sealing sleeve 4 can be pushed out of the water outlet section 6 of the centrifugal pump very conveniently and quickly. the
