Description

Technical Field

[0001] This utility model relates to a tool for disassembling and assembling a profiled turbine impeller, belonging to the field of turbine machinery technology. Background Technology

[0002] As one of the main working components of a turbine expander, the impeller's function is to achieve energy conversion and expansion / cooling of the working fluid through interaction with the high-speed fluid. When the impeller size is too small, the impeller and the bevel screw are usually designed as an integral structure. The shaft below the impeller has threads, which connect to the main shaft of the rotor system. Such an impeller is usually called an integral bevel screw impeller.

[0003] The traditional method of disassembly and assembly involves rotating the top of the integrated umbrella screw impeller with a wrench. However, this method is prone to damage during rotation. In addition, because the top diameter of the integrated umbrella screw impeller is very small, the disassembly and assembly process is very time-consuming and laborious, and cannot achieve high efficiency. Utility Model Content

[0004] This utility model provides a profiled turbine impeller installation tool, which can effectively and quickly assemble and disassemble an integrated umbrella screw impeller, saving time and effort while avoiding damage to the integrated umbrella screw impeller structure.

[0005] To address the aforementioned technical problems, this utility model discloses a tool for disassembling and assembling a profiled turbine impeller, comprising a main body, a handle, an external hexagonal rod, and a blade slot. The handle passes through a circular hole to assemble with the main body. The blade slot engages with the straight section of the impeller blade, thus completing the tool's installation. The handle pre-tightens the impeller by rotating. The external hexagonal rod engages with an internal hexagonal socket, and a torque wrench precisely controls the tightening force to avoid over-tightening or under-tightening. During disassembly, the blade slot engages with the straight section of the impeller blade, and disassembly is completed by rotating the handle.

[0006] As a preferred technical solution of this utility model, the profiled turbine impeller disassembly and assembly tool is designed and used for integrated umbrella screw impellers.

[0007] As a preferred embodiment of this utility model, the inner diameter of the main body is designed according to the size of different impellers.

[0008] As a preferred technical solution of this utility model, the shape of the blade slot is designed to match the blade profile of different impellers.

[0009] As a preferred technical solution of this utility model, the main body, handle and external hexagonal rod are manufactured by 3D printing, with a very short customization cycle, wherein the main body and external hexagonal rod are processed as a whole.

[0010] As a preferred technical solution of this utility model, the main body adopts a hollowed-out design to ensure that it will not interfere with the upper part of the impeller, so that the blade slot can clamp the straight section of the impeller blade.

[0011] The beneficial effects achieved by this utility model are as follows: This impeller disassembly and assembly tool can effectively realize the rapid disassembly and assembly of integrated bevel screw impellers, which not only greatly saves disassembly and assembly time, but also significantly reduces the labor intensity of operators. The disassembly and assembly process becomes simpler and faster. At the same time, it avoids the risk of structural damage that may occur when using traditional wrenches to disassemble integrated bevel screw impellers. This tool not only improves disassembly and assembly efficiency, but also ensures the long-term stable operation of the equipment, reduces the need for later maintenance and replacement of parts, and greatly improves the service life and reliability of turbine machinery.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] like Figure 1 As shown, this utility model provides a tool for disassembling and assembling a profiled turbine impeller, including a main body 1, a handle 2, an external hexagonal rod 3, and a blade slot 4. The handle 2 passes through a circular hole to assemble with the main body 1. The blade slot 4 engages with the straight section of the impeller blade to complete the tool's installation. The handle 2 is rotated to pre-tighten the impeller. The external hexagonal rod 3 cooperates with an internal hexagonal socket, and a torque wrench precisely controls the tightening force to avoid over-tightening or under-tightening. During disassembly, the blade slot 4 engages with the straight section of the impeller blade, and disassembly is completed by rotating the handle 2.

[0019] Furthermore, the profiled turbine impeller assembly and disassembly tool is designed and used for integrated umbrella screw impellers.

[0020] Furthermore, the inner diameter of the main body 1 is designed according to the size of different impellers.

[0021] Furthermore, the shape of the blade slot 4 is designed to match the blade profile of different impellers.

[0022] Furthermore, the main body 1, handle 2, and external hexagonal rod 3 are manufactured using 3D printing, resulting in a very short customization cycle. The main body 1 and external hexagonal rod 3 are machined as a single piece.

[0023] Furthermore, the main body 1 adopts a hollowed-out design to ensure that it will not interfere with the upper part of the impeller, so that the blade slot 4 can clamp the straight section of the impeller blade.

[0024] The working principle of this utility model is as follows: During operation, the handle can be inserted through the round hole to complete the assembly with the main body. The blade slot is then engaged with the straight section of the impeller blade to complete the tool installation. The impeller is pre-tightened by rotating the handle. Then, the external hexagonal rod and internal hexagonal socket are used in conjunction with a torque wrench to precisely control the tightening force, avoiding overtightening or loosening. During disassembly, the blade slot is engaged with the straight section of the impeller blade, and disassembly is completed by rotating the handle.

[0025] This utility model, as a tool for disassembling and assembling a profiled turbine impeller, can effectively achieve rapid disassembly and assembly of an integrated bevel screw impeller. It not only greatly saves disassembly and assembly time but also significantly reduces the labor intensity of operators, making the disassembly and assembly process simpler and faster. At the same time, it avoids the risk of structural damage that may occur when using a traditional wrench to disassemble and assemble an integrated bevel screw impeller.
