Description

Technical Field

[0001] The utility model relates to the technical field of tool design, in particular to a tool for filing and repairing an impeller of a vane pump. Background Technique

[0002] A vane pump is a fluid machinery for transporting liquids, which is widely used in industrial and agricultural fields such as petroleum, chemical industry, water conservancy, and irrigation. Especially in high-tech fields such as nuclear power, aerospace, ships, and submarines, it is an indispensable key equipment.

[0003] The impeller is the core component of the vane pump. By doing work on the liquid through the vanes on it, the pressurization and transportation of the fluid are realized. The vane impeller directly affects the overall performance of the vane pump. The outer diameter of the impeller plays a decisive role in the lift of the vane pump. When the lift of the existing impeller is insufficient, it is mostly necessary to re-mold (open a mold for production and processing after increasing the outer diameter) to achieve the effect of increasing the lift, which is time-consuming, laborious, and costly. At the same time, due to long-term contact with the fluid and being scoured by solid particles, the surface of the impeller may be worn, affecting the efficiency and performance of the pump. Once the impeller is worn, if it is not repaired in time, it will seriously affect the normal operation of the pump and even cause damage to the pump. The existing repair methods mostly rely on manual operation, with low precision, poor efficiency, and it is difficult to achieve an ideal repair effect. Some existing filing tools also have problems such as inaccurate positioning and complex operation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tool for filing and repairing an impeller of a vane pump, so as to solve the problems of re-molding required for increasing the lift of the impeller of the vane pump and insufficient wear repair mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A tool for filing and repairing an impeller of a vane pump, including a reference table surface, a file, and an impeller. The reference table surface is provided with an arc surface that fits the surface of the impeller. A limiting plate is provided at the front end of the arc surface. An opening groove is provided at one end of the arc surface. The file can be located in the opening groove to file and repair the impeller.

[0006] Preferably, the opening groove is connected to the limiting plate.

[0007] Preferably, the two side surfaces of the opening groove are positioning surfaces and termination surfaces, and the positioning surface and the termination surface are parallel to each other.

[0008] Preferably, the limiting plate is of a planar structure and fits the side surface of the impeller cover plate.

[0009] Preferably, the reference table surface is made of steel plate material.

[0010] Preferably, the width of the reference table surface matches the width of the impeller, and the impeller is clamped by the reference table surface during filing and repairing.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: 1. By providing a reference table surface and a file, the present utility model can quickly improve the head parameter of the vane pump by changing the shape of the vane outlet, featuring simple operation and low cost, greatly improving the performance of the vane pump and reducing the mold repair cost.

[0012] 2. Through the arc surface designed on the reference table surface of the present utility model, the tool can be precisely fitted with the surface of the impeller, ensuring that the file can accurately align with the reference table surface of the impeller surface during the filing process, thereby precisely repairing the wear of the vane and ensuring that the surface of the impeller remains smooth after repair, effectively extending the service life of the impeller.

[0013] 3.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1 and Figure 2 For this, the present utility model provides a technical solution: a filing tool for a vane pump impeller, which includes a reference table surface 1, a file 2, and an impeller 3. It is characterized in that: the reference table surface 1 is provided with an arc surface 11 that fits the surface of the impeller 3, ensuring that the file 2 can accurately align with the surface of the impeller during the filing process, improving the filing accuracy. A limit plate 12 is provided at the front end of the arc surface 11, and an opening groove 15 is provided at one end of the arc surface 11. The file 2 can be located in the opening groove 15 to file the impeller 3;

[0024] The opening groove 15 is connected to the limit plate 12, enabling the file 2 to be stably positioned during filing and facilitating the operator to control the filing depth to prevent over-filing;

[0025] The two side surfaces of the opening groove 15 are a positioning surface 13 and a termination surface 14, and the positioning surface 13 and the termination surface 14 are parallel to each other, providing a stable guide for the file and ensuring the stability of the filing process;

[0026] The reference table surface 1 is made of steel plate material, which can increase the service life of the tool. Also, due to its firm and stable characteristics, it reduces the complexity during operation.

[0027] Please refer to Figure 3 For this, the limit plate 12 is of a planar structure and fits the side surface of the impeller 3 cover plate;

[0028] The width of the reference table surface 1 matches the width of the impeller 3, and the reference table surface 1 clamps the impeller 3 during filing.

[0029] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 For this, after filing, the vane impeller becomes narrower and smoother, thereby realizing the repair of vane wear and achieving the effect of increasing the head, which helps to reduce the resistance of the fluid during the pumping process, thereby improving the efficiency of the pump.

[0030] Working principle:

[0031] Place the impeller 3 horizontally with its inlet facing down on a flat ground. Assemble the reference table surface 1 and the file 2 by fitting the positioning surface 13 with the side surface of the file 2. It is required that the positioning surface 13 is flush with the side surface of the file. Use the assembled component to file the impeller 3. The file 2 abuts against the blade outlet. The filing ends when the file 2 moves to the limit plate 12. This method can quickly file the blade outlet to realize the repair of vane wear and achieve the effect of increasing the head.
