Description

Technical Field

[0001] This utility model belongs to the field of pump cover technology, and specifically relates to a pump cover installation tool to prevent incorrect installation. Background Technology

[0002] The pump cover is a key component in pump equipment used to enclose the pump body, support the shaft system, and maintain a seal. It is typically installed at both ends of the pump body or between stages in a segmented pump. Its main functions include preventing media leakage, withstanding internal pressure, securing bearings or sealing devices (such as mechanical seals), and forming a fluid passage with the pump body.

[0003] Incorrect pump cover installation can lead to seal failure, media leakage, and even safety accidents; it can also cause misalignment of bearings, exacerbate wear and vibration, and shorten equipment life; it can affect the direction of media flow, reduce pump head and efficiency, and may cause cavitation; it may also cause friction and collision between the impeller and the pump cover, producing abnormal noise or mechanical damage; if the cooling / lubrication channels are misaligned, it can also cause the system to overheat. Therefore, it is necessary to design the installation structure to prevent incorrect pump cover installation. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a pump cover and installation tool that prevents misinstallation and has uniform load distribution and small pre-tightening force error.

[0005] The objective of this utility model can be achieved through the following technical solution: An installation tool, characterized in that it includes an installation housing with an installation cavity, a driving gear is provided inside the installation housing, and a plurality of driven gears A, driven gears B and idler gears are also provided inside the installation housing. The driven gears B are connected to the driving gear through the idler gears. The bottom of the driven gears A and B are provided with locking components. A transmission rod is provided on the locking components. An elastic connector is provided at the bottom of the transmission rod. An installation sleeve is provided on the elastic connector. A sealing plate is provided at the top of the installation sleeve. A spoke is provided at the bottom of the transmission rod. The spoke is placed inside the installation sleeve. Both the spoke and the sealing plate are provided with interlocking ratchet teeth. A support spring is provided at the bottom of the spoke. One end of the support spring abuts against the inner bottom of the installation sleeve. A bolt connection protrusion is provided at the end of the installation sleeve.

[0006] In the aforementioned anti-misalignment pump cover installation tool, the installation housing is provided with several rotating shafts, and bearings are provided on the rotating shafts. The idler wheel and the drive gear are fixed to the bearings.

[0007] In the aforementioned anti-misinstallation pump cover installation tool, the mounting housing is provided with a cover, the transmission rod passes through and is fixedly connected to driven gear A and driven gear B, and bearings are provided on both sides of the transmission rod, with the sidewalls of the bearings abutting against driven gear A and driven gear B.

[0008] In the aforementioned anti-misinstallation pump cover installation tool, the drive gear is provided with a hexagonal connecting part, which protrudes from the top of the cover.

[0009] Compared with existing technologies, this anti-misinstallation pump cover installation tool uses bolts with different rotation directions to radially lock and fix the snap-fit ​​end cover. Even if the snap-fit ​​end cover adopts a centrally symmetrical result, it can prevent the snap-fit ​​end cover from being installed incorrectly, which would lead to a reduction in installation accuracy. This installation tool uses gears to simultaneously rotate multiple locking bolts to lock the bolts at the same time, increasing work efficiency and installation accuracy.

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1 , 2As shown in Figures 3 and 4, this anti-misalignment pump cover installation tool includes an installation housing 21 with an installation cavity 27. A drive gear 22 is provided inside the installation housing 21. Several driven gears A18, driven gears B26, and idler gears 25 are also provided inside the installation housing 21. Driven gears B26 are connected to the drive gear 22 via idler gears 25. Locking components 20 are provided at the bottom of both driven gears A18 and B26. A transmission rod 13 is provided on the locking component 20. An elastic connector 8 is provided at the bottom of the transmission rod 13. An installation sleeve 7 is provided on the elastic connector 8. A sealing plate 12 is provided at the top of the installation sleeve 7. A spoke 11 is provided at the bottom of the transmission rod 13 and is placed inside the installation sleeve 7. Both the spoke 11 and the sealing plate 12 have interlocking ratchet teeth 9. A support spring 10 is provided at the bottom of the spoke 11, with one end of the support spring 10 abutting against the inner bottom of the installation sleeve 7. The end of the sleeve 7 is provided with a bolt connection protrusion 19. When installing the snap-fit ​​end cover 3, place this installation tool on the top of the pump cover body 4 and connect the bolt connection protrusion 19 to the locking bolt 2. Drive the drive gear 22, and rotate the moving rod through the driven gear to rotate the locking bolt 2. Control the speed of bolt locking through the gear, so that multiple locking bolts 2 are locked at the same time, reducing preload error and increasing the installation accuracy of the locking bolt 2. The driven gear B26 is connected to the drive gear 22 through the idler gear 25. Its rotation direction is opposite to that of the driven gear A18. The corresponding rotation direction of the locking bolt 2 is also the same. Bolts with different locking directions can prevent errors during installation. At the same time, inconsistent rotation directions can reduce the torsion generated by the installation tool, making this installation tool easier to control. The rotation direction of the threads in the corresponding mounting screw hole 15 and locking screw hole 16 is also opposite.

[0017] Preferably, the mounting housing 21 is provided with a plurality of rotating shafts 23, and bearings 24 are provided on the rotating shafts 23. The idler gear 25 and the drive gear 22 are fixed on the bearings 24.
