Description

Technical Field

[0001] This utility model relates to the field of special tool technology, and more specifically, to an impeller limiting tool. Background Technology

[0002] A pump is a rotating machine used to transport or pressurize fluids, transferring the mechanical energy of a rotor to a liquid, thus increasing the liquid's energy. For example, pumps are frequently used in the dairy industry to transport liquid dairy products.

[0003] In related technologies, the pump rotor and impeller are connected by a lock nut. The impeller must be removed each time the material pump motor bearings are maintained or the mechanical seal is replaced. However, during impeller removal, the lock nut requires significant tightening force, necessitating that the impeller be limited to restrict its rotation before the screws can be removed. Current methods use an Allen wrench or screwdriver to limit the impeller's movement.

[0004] However, the above disassembly and assembly methods sometimes fail to hold the impeller in place when using an Allen wrench or screwdriver to limit its position, and there is a risk of damaging the impeller. In addition, each disassembly of the impeller takes about 10 minutes, which affects maintenance efficiency. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] like Figures 1 to 3 As shown, this utility model embodiment provides an impeller limiting tool, which includes a limiting seat 10 and a limiting member 20. The limiting seat 10 includes a first connecting seat 11 and a second connecting seat 12. Both the first connecting seat 11 and the second connecting seat 12 extend laterally and are movably connected. The first connecting seat 11 can move laterally relative to the second connecting seat 12. Both the first connecting seat 11 and the second connecting seat 12 have a pump housing connection portion. The limiting member 20 is movably disposed longitudinally on the first connecting seat 11 and / or the second connecting seat 12. The limiting member 20 can protrude from the surface of the first connecting seat 11 and the surface of the second connecting seat 12.

[0026] Applying the technical solution of this utility model, the impeller limiting tool includes a limiting seat 10 and a limiting member 20. A first connecting seat 11 and / or a second connecting seat 12 are connected to the pump casing via a pump casing connecting part. The position of the first connecting seat 11 relative to the second connecting seat 12 is adjusted, and the first connecting seat 11 and the second connecting seat 12 are limited to fix the limiting seat 10 to the pump casing. The position of the limiting member 20 is adjusted longitudinally so that the limiting member 20 protrudes from the surface of the first connecting seat 11 and the surface of the second connecting seat 12, and extends between two adjacent blades of the impeller. This allows the limiting member 20 to limit the impeller, preventing excessive rotation angle and enabling the removal of the impeller's locking nut using a wrench. Compared to disassembly methods in related technologies, the impeller limiting is more stable and improves disassembly and assembly efficiency.

[0027] It should be noted that if the pump is small in size, it can be connected to the pump casing using only the first connecting seat 11 or the second connecting seat 12. When using the first connecting seat 11, the limiting member 20 should be provided on the first connecting seat 11. When using the second connecting seat 12, the limiting member 20 should be provided on the second connecting seat 12.

[0028] Furthermore, in order to properly match the impeller and better limit the impeller, the limiting member 20 can be connected in a lateral sliding manner.

[0029] One of the first connecting seat 11 and the second connecting seat 12 may be provided with a pump housing connecting part, or both may be provided with a pump housing connecting part.

[0030] It should be noted that the ability of the first connecting seat 11 to move laterally relative to the second connecting seat 12 means that the first connecting seat 11 can move laterally in a straight line relative to the second connecting seat 12, and at the same time, the first connecting seat 11 can rotate relative to the second connecting seat 12, with the axis of rotation extending longitudinally.

[0031] like Figure 1 and Figure 3 As shown, the limiting member 20 includes a limiting shaft 21, which is movably mounted on the first connecting seat 11 along the longitudinal direction. The limiting shaft 21 moves on the first connecting seat 11 and limits the impeller, which has the advantages of simple structure and easy operation.

[0032] like Figure 1As shown, the limiting member 20 also includes an adapter 22, which is disposed on the first connecting seat 11 and extends laterally. The limiting shaft 21 is movably disposed on the adapter 22 in the longitudinal direction and is threadedly connected to the adapter 22. Using the adapter 22 to arrange the limiting shaft 21 improves the flexibility of the limiting shaft 21's arrangement position, ensuring that the limiting shaft 21 does not interfere with either the first connecting seat 11 or the second connecting seat 12 when the first connecting seat 11 and the second connecting seat 12 move relative to each other.

[0033] like Figure 1 As shown, the adapter 22 has a protrusion 221 that protrudes from the first connecting seat 11, and the limiting shaft 21 is connected to the protrusion 221. With the above structure, by setting the protrusion 221 to protrude from the first connecting seat 11, the limiting shaft 21 can be arranged outside the first connecting seat 11, so that the limiting shaft 21 will not interfere with either the first connecting seat 11 or the second connecting seat 12.

[0034] In this embodiment, both ends of the adapter 22 are provided with protrusions 221, which protrude from the first connecting seat 11. Each protrusion 221 is provided with a limiting shaft 21, thereby improving the flexibility of the arrangement of the limiting shaft 21 and enabling more flexible limiting cooperation with the impeller.

[0035] like Figure 2 As shown, in the longitudinal direction, the adapter 22 and the second connecting seat 12 are located on both sides of the first connecting seat 11. With the above structure, when the first connecting seat 11 moves relative to the second connecting seat 12, the adapter 22 will not interfere with either the first connecting seat 11 or the second connecting seat 12.

[0036] like Figure 1 As shown, the first connecting seat 11 and the second connecting seat 12 are arranged longitudinally. The first connecting seat 11 is provided with a first strip groove 111, and the second connecting seat 12 is provided with a second strip groove 121. The limiting seat 10 also includes a first connecting member 14, which passes through the first strip groove 111 and the second strip groove 121 to connect the first connecting seat 11 and the second connecting seat 12. With the above structure, by using the first connecting member 14 passing through the first strip groove 111 and the second strip groove 121, the first connecting seat 11 and the second connecting seat 12 can move and rotate relative to each other, improving the arrangement flexibility of the limiting seat 10 and allowing for more flexible limiting engagement with the impeller.

[0037] In this embodiment, there are two first strip grooves 111 and two strip grooves 121, and a first connector is provided in each of the two first strip grooves 111 and two strip grooves 121.

[0038] The end of the limiting component 20 is provided with a rubber sleeve. The rubber sleeve can prevent the limiting component 20 from hitting the impeller, thereby improving disassembly efficiency while ensuring disassembly quality.

[0039] In related technologies, when using an Allen wrench or screwdriver to jam the impeller, the surface of the impeller may be bumped. Using a rubber sleeve can reduce the contact stress when the limiting part 20 contacts the impeller, thus avoiding damage to the impeller.

[0040] like Figure 2 As shown, the first connecting seat 11 includes a fixed seat 112 and an adjusting seat 113. The adjusting seat 113 can move longitudinally relative to the fixed seat 112. A limiting member 20 is disposed on the fixed seat 112, and the pump casing connecting part is disposed on the adjusting seat 113. With the above-described structure, the first connecting seat 11 allows the fixed seat 112 to avoid obstructing the impeller when the pump casing is connected using the adjusting seat 113, thereby improving the usability of the tool.

[0041] In this embodiment, the second connecting seat 12 also includes a fixed seat and an adjusting seat.

[0042] like Figure 2 As shown, the fixed base 112 includes a first longitudinal plate 1121 and a first transverse plate 1122 connected together. The adjusting base 113 includes a second longitudinal plate 1131 and a second transverse plate 1132 connected together. A limiting member 20 is disposed on the first transverse plate 1122, and a pump housing connecting part is disposed on the second transverse plate 1132. A third strip groove is provided on the first longitudinal plate 1121, and a fourth strip groove is provided on the second longitudinal plate 1131. The limiting base 10 also includes a second connecting member 15, which passes through the third and fourth strip grooves to connect the first longitudinal plate 1121 and the second longitudinal plate 1131. Using the above structure, the relative positions of the fixed base 112 and the adjusting base 113 are adjusted by providing strip grooves on the first longitudinal plate 1121 and the second longitudinal plate 1131, which has the advantages of simple structure and easy operation.

[0043] like Figure 2 As shown, both the first connecting seat 11 and the second connecting seat 12 are provided with clearance holes 13, and the pump casing connection part includes a third connecting member that passes through the clearance hole 13 and connects to the pump casing. Using the above structure, the method of connecting the limiting seat 10 and the pump casing through the third connecting member has the advantages of simple structure and easy operation.

[0044] In this embodiment, the first connector 14, the second connector 15, and the third connector are all bolts.
