Description

Technical Field

[0001] The utility model relates to the technical field of a multi-stage centrifugal pump supporting structure, in particular to a replaceable multi-stage centrifugal pump supporting structure. Background Art

[0002] The temperature in some factories is relatively high. For example, metal casting and boiler rooms will generate a lot of high temperature, which will cause the risk of fire. Generally, fire-fighting pressure-stabilizing pumps will be installed in large factories to deliver water for firefighting in time. The pressure-stabilizing pumps used for firefighting are generally multi-stage centrifugal pumps. The multi-stage centrifugal pumps generally used are 10-stage, which are mainly used for water delivery and some oil delivery. When the multi-stage centrifugal pump is used, multiple wheels for water delivery will be installed on the pump shaft. These wheels will generate centrifugal force under high-speed rotation, which will cause the casing of the centrifugal pump to vibrate after being installed on the bracket. The stress generated by the vibration of the centrifugal pump for a long time will damage the bracket. In addition, there is a high humidity in the boiler room. The continuous vibration of the centrifugal pump can easily cause the supporting structure to deform when it is constantly receiving stress, which will cause the waterproof paint to crack or even fall off, and then cause moisture to erode the supporting structure, and then the supporting structure of the centrifugal pump needs to be replaced. At the same time, centrifugal pumps that have been used for a long time also need to be replaced after being used for too long.

[0003] In the prior art, when replacing the bracket, the multi-stage centrifugal pump needs to be removed first, and then the supporting structure is replaced. After the bracket is replaced, the multi-stage centrifugal pump is installed on the supporting structure. However, when disassembling the supporting structure, the multi-stage centrifugal pump needs to be removed, which takes a certain amount of time. In addition, there are also connecting parts between the multi-stage centrifugal pump and the supporting structure that also need to be removed, thereby increasing the time required for replacing the supporting structure and reducing the efficiency of replacing the supporting structure. Utility Model Content

[0009] By adopting the above technical solution, the auxiliary support platform and the auxiliary arc groove are set, so that when the auxiliary support platform rises upward, it will drive the multi-stage centrifugal pump body to rise, thereby facilitating the replacement of the bearing platform, saving the time of dismantling and moving the multi-stage centrifugal pump body, and improving the efficiency of replacing the bearing platform.

[0011] By adopting the above technical solution, the air pump is arranged to cooperate with the transmission pipe, so that the air in the transmission pipe is transported to the connecting pipe, driving the lifting of the auxiliary support platform, thereby facilitating the lifting of the multi-stage centrifugal pump body.

[0012] In a preferred example, the utility model can be further configured as follows: cavities are relatively opened in the auxiliary support platform, the piston in the cavity is connected to a cavity tube, the bottom end of the cavity tube extends into the platform and is fixedly connected to the platform, and the end of the connecting tube is connected to the corresponding cavity tube.

[0013] By adopting the above technical solution, the cavity groove is arranged to cooperate with the cavity tube, so that the gas is input into the cavity tube when the air pump delivers gas, thereby increasing the air pressure in the cavity tube and increasing the air pressure in the cavity groove, so that the auxiliary support platform is lifted by the air pressure, thereby facilitating the lifting of the multi-stage centrifugal pump body and facilitating the replacement of the support platform.

[0014] In a preferred example, the utility model can be further configured as follows: two positioning blocks are relatively installed on two sides of the platform, and a spring damper is installed between the positioning block and the multi-stage centrifugal pump body.

[0015] By adopting the above technical solution, the spring damper is arranged to reduce the vibration of the multi-stage centrifugal pump when it is working and rotating, so as to prevent the bearing platform from being deviated, thereby causing the multi-stage centrifugal pump body to be deviated and affecting the connected pipeline.

[0016] In a preferred example, the utility model can be further configured as follows: the conveying tube does not contact the bottom side of the chute, the bottom end of the cavity tube is closed, and the top end of the cavity tube is open.

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0028] Example:

[0029] Reference Figure 1-Figure 4The utility model discloses a replaceable multi-stage centrifugal pump support structure, including a platform 1 and a multi-stage centrifugal pump body 2.

The slot 5 is clamped, and the top sides of several of the sliding rods 4 are fixedly connected with a bearing platform 8, the bearing platform 8 is trapezoidal, and the top side of the bearing platform 8 is provided with an arc groove 9 matching the multi-stage centrifugal pump body 2, and the bottom side of the arc groove 9 is provided with a limiting groove 10, and a limiting arc plate 11 is installed on the bottom side of the multi-stage centrifugal pump body 2, and the multi-stage centrifugal pump body 2 is clamped with the limiting groove 10 through the limiting arc plate 11, and an auxiliary component 12 is installed on the end side of the platform 1.

[0030] In this embodiment, when the support structure is installed, the bearing platform 8 is inserted into the slide groove 3 through the slide rod 4 and slid to the other end, so that the two ends of the slide rod 4 are flush with the two sides of the platform 1, and then the clamping rod 7 on the limit plate 6 is inserted into the clamping groove 5 of the slide rod 4, so that the limit plate 6 fits the platform 1 to limit a number of bearing platforms 8, wherein the limit plate 6 needs to be fixed to the platform 1 by bolts to prevent displacement during installation, and then the limit arc plate 11 is installed on the multi-stage centrifugal pump body 2, so that the arc limit plate 6 and the arc groove 9 on the bearing platform 8 correspond to each other, and then the limit arc plate 11 is clamped into the limit groove 10 in the arc groove 9, thereby completing the multi-stage centrifugal pump body. 2, the support structure is convenient for disassembly and installation during use, and can be quickly positioned and centered when installing the multi-stage centrifugal pump body 2, thereby increasing the efficiency of installing the multi-stage centrifugal pump body 2. When replacing the bearing platform 8, the multi-stage centrifugal pump body 2 is lifted by the auxiliary component 12. At this time, the bearing platform 8 is not in contact with the multi-stage centrifugal pump body 2, and then the bearing platform 8 is pushed so that the bearing platform 8 and the slide bar 4 are separated from the slide groove 3, and a new bearing platform 8 is replaced and installed on the platform 1, and then the auxiliary component 12 is started to connect the multi-stage centrifugal pump body 2 with the new bearing platform 8, so as to achieve the effect of quickly replacing the bearing platform 8 to improve the installation efficiency and quickly center the multi-stage centrifugal pump body 2 during installation.

[0031] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the auxiliary component 12 includes two auxiliary support platforms 13, both of which are trapezoidal in shape, and an auxiliary arc groove 14 is opened on the top side of the auxiliary support platform 13, and the inner side wall of the auxiliary arc groove 14 does not contact the multi-stage centrifugal pump body 2.

[0032] In this embodiment, auxiliary arc grooves 14 are arranged on the top sides of the two auxiliary support platforms 13 to increase the contact area with the multi-stage centrifugal pump body 2 when the multi-stage centrifugal pump body 2 is lifted, and can provide support for the multi-stage centrifugal pump body 2. When not in use, the auxiliary support platforms 13 do not contact the multi-stage pump body, so that the auxiliary support platforms 13 will not be affected by the vibration of the multi-stage centrifugal pump body 2. Therefore, the waterproof paint applied on the auxiliary support platforms 13 will not be deformed and fall off due to long-term vibration, and can be used for a long time.

[0033] In a further preferred embodiment of the present invention, Figure 1-4 As shown, an air pump 15 is installed on the end side of the platform 1, and the output end of the air pump 15 is connected to a transmission pipe 16, which extends to the other end of the platform 1 and is installed with a switch valve 17. A connecting pipe 18 is provided below the two auxiliary support platforms 13 in the platform 1, and the connecting pipe 18 is connected to the transmission pipe 16.

[0034] In this embodiment, the air pump 15 is used as the main drive to lift the auxiliary support platform 13. The air supply of the air pump 15 is carried out through the transmission pipe 16 and the connecting pipe 18 to provide a driving source. The switch valve 17 is directly opened when the auxiliary support platform 13 is lowered to discharge the gas. The caliber of the switch valve 17 will make the exhaust efficiency low, so that the auxiliary support platform 13 will slowly descend to prevent the multi-stage centrifugal pump body 2 from colliding and being damaged due to a rapid descent.

[0035] In a further preferred embodiment of the present invention, Figure 1-4 As shown, a cavity 19 is relatively opened in the auxiliary support platform 13, and a piston in the cavity 19 is connected to a cavity tube 20. The bottom end of the cavity tube 20 extends into the platform 1 and is fixedly connected to the platform 1, and the end of the connecting tube 18 is connected to the corresponding cavity tube 20.

[0036] In this embodiment, when gas is injected into the cavity tube 20 through the connecting tube 18, the air pressure in the cavity tube 20 will increase, and then the cavity groove 19 is connected to the cavity tube 20, so the air pressure in the cavity groove 19 will also increase accordingly. Subsequently, due to the continuous increase in air pressure in the cavity groove 19, the auxiliary support platform 13 and the cavity tube 20 will perform piston movement, and then the auxiliary support platform 13 will be lifted, thereby driving the multi-stage centrifugal pump body 2 to lift, and then the multi-stage centrifugal pump body 2 will be separated from the support of the supporting platform 8, thereby facilitating the replacement of the supporting platform 8.

[0037] In a further preferred embodiment of the present invention, Figure 1-4 As shown, two positioning blocks 21 are installed relatively to each other on both sides of the platform 1, and a spring damper 22 is installed between the positioning block 21 and the multi-stage centrifugal pump body 2.

[0038] In this embodiment, the spring damper 22 is set to increase the stress between the bearing platform 8 and the multi-stage centrifugal pump body 2 when the bearing platform 8 is used for support, so that the stability of the multi-stage centrifugal pump body 2 is improved when the bearing platform 8 is used for support, the intensity of vibration is reduced, and the life of the bearing platform 8 is increased.

[0039] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the conveying tube 16 does not contact the bottom side of the chute 3, the bottom end of the cavity tube 20 is closed, and the top end of the cavity tube 20 is open.

[0040] In this embodiment, the opening position and the closed end position of the cavity tube 20 are set to facilitate the use of air pressure to lift the auxiliary support platform 13 when the air pump 15 injects air, thereby facilitating the replacement of the carrier platform 8.

[0041] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
