Description

Technical Field

[0001] This utility model relates to the field of maintenance tools, and in particular to a simple maintenance tool for chemical centrifugal pumps. Background Technology

[0002] Centrifugal pumps are the most commonly used fluid machinery in petrochemical and chemical processes. They are power machines used to transport liquids and increase their energy. They are important equipment to ensure continuous production in chemical enterprises. Once a centrifugal pump fails, it will cause incalculable losses to the enterprise.

[0003] During the inspection and maintenance of centrifugal pumps, it is often necessary to replace sealed bearings or disassemble and repair their components. Among these, the ferrule-type components are difficult to disassemble with conventional tools such as wrenches and hammers. Due to the pump's unique structure, such as the large-diameter nest and connecting rod, the pump needs to be disassembled quite a bit to remove and repair them. This disassembly process is time-consuming, inefficient, and can easily damage the pump body components. Utility Model Content

[0004] The purpose of this utility model is to provide a simple maintenance tool for chemical centrifugal pumps to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A simple maintenance tool for a chemical centrifugal pump includes a column and a connecting rod. The column has a first through hole and a second through hole perpendicular to each other. The first through hole extends vertically from the center of one side of the column to the center of the other side. The second through hole extends vertically from the side wall of the column, penetrating the column. Two protrusions are provided on the side of the column away from the second through hole, and the two protrusions are horizontally located at both ends of one side of the column. The connecting rod includes a threaded portion and a smooth portion. The diameter of the threaded portion is smaller than the diameter of the smooth portion. An annular step is formed at the connection between the threaded portion and the smooth portion. A first stop is fixedly connected to one end of the smooth portion, and a second stop is threadedly connected to the annular step. A first nut and a second nut are threadedly connected to the threaded portion. The inner diameter of the first through hole is larger than the diameter of the smooth portion, and the inner diameter of the second through hole matches the diameter of the threaded portion.

[0007] Preferably, the column passes through the threaded portion of the connecting rod via the second through hole and is located on the second stop block, and is connected to the threaded portion at the top of the column by the first nut for fixing the column.

[0008] Preferably, the column passes through the first through hole and is movably located on the smooth rod section through the threaded portion of the connecting rod. The second stop is threadedly connected to the annular step through the threaded portion. The column is slidably disposed on the smooth rod section between the first stop and the second stop. Two second nuts are connected at intervals at the top of the threaded portion, and a clamping component is disposed between the two second nuts.

[0009] Preferably, the column is a cylindrical structure.

[0010] Preferably, the first stop is a conical cylindrical structure and the second stop is a nut structure.

[0011] Preferably, the second nut includes a nut that matches the size of the clamped component.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The column of this utility model is set on the connecting rod in different forms through the first through hole and the second through hole, so as to realize two functions;

[0014] The column is set in the threaded part of the connecting rod through the second through hole to form an external wrench. The protrusion on the column serves as the fulcrum for embedding the part. With this as the center, the connecting rod is rotated to pry open the part.

[0015] The column is set in the smooth part of the connecting rod through the first through hole to form an external part removal tool. The part to be removed is clamped and fixed by two second nuts. The column slides back and forth on the smooth part. The kinetic energy of the column's gravity inertia is used to remove the part connected at the second nut.

[0016] This utility model improves the efficiency of disassembling centrifugal pumps and reduces damage to pump body components through a maintenance tool that combines two methods, saving time and effort. Attached Figure Description

[0026] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0027] Example 1

[0028] like Figure 1-3 As shown, a simple repair tool for a chemical centrifugal pump includes a column 1 and a connecting rod 2. The column 1 is a cylindrical structure. A first through hole 11 and a second through hole 12 perpendicular to each other are opened in the column 1. The first through hole 11 extends vertically from the center of one side of the column 1 to the center of the other side. The second through hole 12 extends vertically from the side wall of the column 1 and penetrates the column 1. Two protrusions 13 are provided on the side of the column 1 away from the second through hole 12. The two protrusions 13 are horizontally located at both ends of one side of the column 1. The two protrusions 13 are used to pry the part to be removed.

[0029] like Figure 4-5 As shown, the connecting rod 2 includes a threaded portion 21 and a smooth portion 22. The diameter of the threaded portion 21 is smaller than the diameter of the smooth portion 22. An annular step 23 is formed at the connection between the threaded portion 21 and the smooth portion 22. A first stop 24 is fixedly connected to one end of the smooth portion 22. The first stop 24 is a conical cylindrical structure. A second stop 25 is threadedly connected to the annular step 23. The annular step 23 supports and limits the second stop 25. The second stop 25 is a nut structure, which supports and limits the column 1. A first nut 3 is threadedly connected to the threaded portion 21 to fix the column 1. The inner diameter of the second through hole 12 matches the diameter of the threaded portion 21.

[0030] The column 1 passes through the second through hole 12 and the threaded part 21 of the connecting rod 2, and is located on the second stop 25 to form an external wrench. The first nut 3 is connected to the threaded part 21 at the top of the column 1. The column 1 is fixed by tightening the first nut 3. The protrusion 13 on the column 1 serves as the fulcrum for embedding the part. With this as the center, the connecting rod 2 is rotated to pry the part.

[0031] Example 2

[0032] like Figure 6-7As shown, firstly, the second stop 25 is removed through the threaded part 21. The inner diameter of the first through hole 11 is larger than the diameter of the smooth rod part 22. The column 1 passes through the first through hole 11 and moves on the smooth rod part 22 through the threaded part 21 of the connecting rod 2. Then, the second stop 25 is threadedly connected to the annular step 23 through the threaded part 21. The column 1 is slidably set at the smooth rod part 22 between the first stop 24 and the second stop 25 to form an external tool for picking up parts. Two second nuts 4 are connected at intervals at the top of the threaded part 21. The clamped part 5 is set between the two second nuts 4. The second nuts 4 are selected to match the size of the clamped part 5.

[0033] The component to be removed is clamped and fixed by tightening two second nuts 4. The column 1 slides back and forth on the smooth rod 22. The component connected at the second nut 4 is removed by the kinetic energy of the column 1's gravity inertia.

[0034] The column 1 of this utility model is set on the connecting rod 2 in different forms through the first through hole 11 and the second through hole 12 to realize two functions; the maintenance tool with the combination of the two methods improves the efficiency of disassembling the centrifugal pump and reduces damage to the pump body components, saving time and effort.
