Description

Technical Field

[0001] This utility model relates to the field of booster pump inlet ring technology, specifically to a device for grinding booster pump inlet rings. Background Technology

[0002] Booster pump inlet rings are typically made of cast iron, brass, or stainless steel. The booster pump inlet ring serves the following functions:

[0003] Sealing function: to prevent the medium at the pump outlet from flowing back to the inlet, forming a narrow and tortuous channel between the impeller and the pump casing, increasing the resistance to medium flow and reducing medium leakage.

[0004] Wear-resistant protection: Prevents direct contact between the impeller and pump casing, protecting both the impeller and pump casing. The wear ring can be repaired or replaced after wear, which is more economical and convenient than replacing the impeller or pump casing.

[0005] In actual use, due to the machining accuracy of the booster pump inlet ring or the need to leave a grinding allowance, the inner diameter of the booster pump inlet ring is usually slightly smaller than the standard diameter. Therefore, it is necessary to grind the inside of the booster pump inlet ring. However, grinding the ring-shaped booster pump inlet ring is not easy and it is difficult to perform continuous grinding for a full circle. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0027] Example 1:

[0028] Please see Figure 1-5 This utility model provides a technical solution: a grinding device for the inlet ring of a booster water pump, comprising: a front plate 2, a back plate 1, two drive motors 13, a drive rubber wheel 15, and a grinding wheel 14;

[0029] The front plate 2 is arranged parallel to the front side of the back plate 1, and the front plate 2 and the back plate 1 are connected by a support column 3. The lower left and lower right sides of the front surface of the front plate 2 are rotatably connected to support rollers 5 through support shafts. The support rollers 5 are used to support the booster pump port ring. The drive motor 13 is arranged on the back plate 1 and can swing relative to the back plate 1 and the front plate 2. The drive rubber wheel 15 and the grinding wheel 14 are respectively connected to the output shafts of the two drive motors 13. The front plate 2 has movable grooves 6 corresponding to the positions of the drive rubber wheel 15 and the grinding wheel 14.

[0030] Analysis of the above content: Setting: When the grinding wheel 14 and the drive motor 13 corresponding to the grinding wheel 14 swing to the point where it can no longer swing down, the grinding wheel 14 reaches the lower stop point. At the same time, the inner wall of the booster water pump port ring is finished being ground. The grinding wheel 14 is then inspected and replaced according to the frequency and intensity of use.

[0031] In use, the lower side of the booster pump inlet ring is supported on three support rollers 5. The drive rubber wheel 15 and the grinding wheel 14 are located inside the booster pump inlet ring. When grinding, the two drive motors 13 and their drive rubber wheels 15 and grinding wheels 14 are manually rotated so that the drive rubber wheel 15 is in contact with the booster pump inlet ring. In this way, the drive motor 13 drives the booster pump inlet ring to rotate through the drive rubber wheel 15. The other drive motor 13 drives the grinding wheel 14 to rotate. The grinding wheel 14 contacts the inner wall of the booster pump inlet ring and grinds the inner wall of the booster pump inlet ring. It can be removed after grinding for a period of time and measured manually until the usage requirements are met.

[0032] The drive motor 13 can be powered by an external power supply circuit, and an external switch can control the start and stop of the drive motor 13.

[0033] Example 2:

[0034] Please see Figure 1-5 Based on Embodiment 1, this utility model provides a technical solution: there are two support rollers 5 on the lower left side of the front surface of the front plate 2 and one support roller 5 on the lower right side of the front surface. The front ends of the two support rollers 5 on the lower left side are provided with an outer protective plate 4. The outer protective plate 4 is connected to the front end of the support shaft of the support roller 5 by a nut.

[0035] Analysis of the above content: The outer protective plate 4 is fixed to the front surface of the front plate 2 by means of studs, nuts and other structures, and is also connected to the front end of the support shaft of the support roller 5 by nuts. This plays a stabilizing role for the support roller 5 and avoids insufficient support force during grinding.

[0036] Example 3:

[0037] Please see Figure 1-5 The present invention provides a technical solution based on Embodiment 1: a movable groove 7 is provided on the back plate 1, the drive motor 13 passes through the movable groove 7, the front end of the output shaft of the drive motor 13 passes through the corresponding movable groove 6, and the drive rubber wheel 15 and the grinding wheel 14 are located in front of the corresponding movable groove 6.

[0038] Analysis of the above content: The movable slot 6 is used for the output shaft of the drive motor 13 to pass through, and its trajectory is consistent with the movement trajectory of the drive motor 13 in the movable slot 7, so as to avoid friction between the movable slot 6 and the output shaft of the drive motor 13.

[0039] Example 4:

[0040] Please see Figure 1-5This utility model provides a technical solution based on Embodiment 3: A motor base 8 is provided on the front side of the outer wall of the drive motor 13. The motor base 8 is fixedly connected to the housing of the drive motor 13. A swing arm 16 is fixedly connected to the outer wall of the motor base 8.

A support spring 17 is connected to one side of the swing arm 16, and the other end of the support spring 17 is connected to the front wall of the back plate 1. A rotating and moving groove 12 is provided on the outer wall of the motor base 8. A motor insertion groove 9 is provided on the rear side of the interior of the motor base 8. The front end of the drive motor 13 is inserted into the motor insertion groove 9. A connecting screw hole 11 is provided on the side wall of the motor base 8. A channel 10 is provided on the front middle side of the motor base 8, and the output shaft of the drive motor 13 passes through the channel 10.

[0041] Analysis of the above content: When the drive motor 13 swings, the finger is inserted into the rotation and movement slot 12 of the motor base 8 (a toggle plate can also be fixedly installed on the surface of the motor base 8, and the motor base 8 can be pushed and swung by hand with the toggle plate), the motor base 8 rotates and swings, the motor base 8 swings around the pin based on the swing arm 16, and the swing arm 16 swings around the pin in the movement slot 7 along the trajectory of the movement slot 7.

[0042] When the motor base 8 swings, the support spring 17 deforms to generate elastic force, which facilitates subsequent elastic reset.
