Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and specifically to a centrifugal pump impeller dynamic balance testing system. Background Technology

[0002] Deviations in the outer diameter of a centrifugal pump impeller, i.e., the radius of rotation of the outer edge of the centrifugal pump, can lead to an imbalance in the impeller's center of gravity, unstable operation, and high noise levels. If the outer diameter is too large, it can also cause interference between the impeller and the guide ring, resulting in structural damage. Therefore, the outer diameter of the impeller is a key quality control point.

[0003] Existing methods for inspecting the outer diameter of impellers involve manual inspection by workers using rulers and measuring tapes, resulting in large errors and low efficiency. In particular, it is difficult to detect quality issues such as impeller center of gravity misalignment. The present invention discloses an impeller inspection device in publication number CN104567656A, comprising: a base; a shaft seat mounted on the base; and a position detection unit mounted on the base and spaced apart from the shaft seat in the radial direction. Applying the technical solution of this invention, it is possible not only to detect whether the impeller interferes with the guide ring (i.e., whether the impeller radius is greater than or equal to the guide ring radius), but also to measure the size of each blade, thereby deriving the degree of impeller center of gravity deviation from the shaft center to determine whether the impeller is qualified. Furthermore, since the impeller is fixed to the shaft seat and the inspection is performed using the position detection unit mounted on the base, the inspection accuracy is high, and the efficiency of impeller inspection is also improved.

[0004] However, the testing equipment is inconvenient to operate during the testing of both sides of the impeller, resulting in inaccurate measurement results. Therefore, this application relates to a centrifugal pump impeller dynamic balancing testing system. Summary of the Invention

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figure 1-3As shown, this invention is a centrifugal pump impeller dynamic balancing testing system, including a conveyor frame 1. Two symmetrical conveyor belts 11 are arranged inside the conveyor frame 1. The conveyor belts 11 are driven by a motor, and there is a gap between the two conveyor belts 11. Two sets of three-dimensional adjustment structures 3 are arranged on the conveyor frame 1. A scanner 4 is installed on the three-dimensional adjustment structure 3. A three-dimensional scanner imaging system has been disclosed in publication number CN114234843A. The scanner 4 is used to scan and measure the shape profile of the impeller 2. A flipping mechanism 5 is arranged between the two sets of three-dimensional adjustment structures 3. A clamping mechanism 9 is arranged below both the flipping mechanism 5 and the three-dimensional adjustment structure 3. A limit mechanism 8 is arranged inside the conveyor frame 1 and below the three-dimensional adjustment structure 3, the flipping mechanism 5, and the transfer mechanism 7. A transfer mechanism 7 is arranged at the end of the conveyor frame 1. A parameter processor 6 is also arranged on one side of the conveyor frame 1.

[0034] The flipping mechanism 5 includes a frame 51. A cylinder 6 52 is vertically mounted on one side of the top of the frame 51. An inverted T-shaped sliding plate 53 is slidably connected to the center of one side of the frame 51. The piston rod of the cylinder 6 52 is connected to the T-shaped sliding plate 53. A fixed moving plate 58 is vertically mounted on the bottom of the T-shaped sliding plate 53. A cylinder 8 57 is horizontally mounted on the T-shaped sliding plate 53. The cylinder 8 57 can also be a bidirectional cylinder, and the moving plates on both sides can be adjusted synchronously. A vertically arranged movable moving plate 514 is fixedly mounted on the piston rod of the cylinder 8 57. A reducer 510 is provided on one side of the movable moving plate 514. The reducer 510 drives the fixed clamping plate 511 to rotate through a shaft. A rotary motor 59 is mounted on the reducer 510. The movable moving plate 514 is slidably connected to the T-shaped sliding plate 53. The fixed clamping plate 511 is rotatably connected to the inner side of both the movable moving plate 514 and the fixed moving plate 58.

[0035] One of the fixed clamping plates 511 has support sleeves 512 installed at both ends, and the other fixed clamping plate 511 has electric telescopic rods 513 installed at both ends. The electric telescopic rods 513 are adapted to the support sleeves 512. During the flipping process, the upper and lower surfaces of the impeller can be supported by the support sleeves 512 and the electric telescopic rods 513 to ensure the stability of its rotation. When the support is not needed, the electric telescopic rods 513 can be retracted, and at the same time, they play a role in transmission drive.

[0036] A limiting rack 54 is provided on one side of the sliding plate 53, and a cylinder 7 55 is fixedly installed on one side of the frame 51. A limiting post 56 is fixedly installed at the end of the piston rod of the cylinder 7 55. The limiting post 56 is adapted to the limiting rack 54. The limiting post 56 is inserted into the teeth of the limiting rack 54 to mechanically limit the movement of the cylinder, thus providing good protection.

[0037] The impeller 2 is placed on two conveyor belts 11 and conveyed manually or by a robotic arm. When it moves below the first set of three-dimensional adjustment structures 3, it is limited by a limiting mechanism and clamped from the inside to fix it, pushing the impeller upward to ensure its balance and facilitate inspection. A scanner scans the upper surface of the impeller, and its overall contour information is sent to a parameter processor for processing. The conveying continues, and when it reaches below the flipping mechanism 5, it is clamped from the center of the impeller 2 by a clamping mechanism and lifted up. Then, cylinder six 52 is activated to drive the sliding plate 53 to descend, and cylinder eight 57 is activated to drive the moving plate 514 to move. The impeller 2 is clamped by two fixed clamping plates 511. The clamping mechanism releases and descends, and then the rotary motor 59 is activated to drive the fixed clamping plates 511 to rotate, thereby causing the impeller 2 to flip. Release the impeller 2 and transport it to the underside of the scanner 2. Scan its lower surface and transmit the scanned information to the parameter processor 6. By scanning both sides, the measurement results are more accurate. The parameter processor 6 processes the contour information of the two scans and measures the thickness, width, length, and other information of each blade of the impeller. Then, it is determined whether it is qualified. Because the size of each blade is different, the degree of deviation of the impeller's center of gravity from the axis will also be different. CN104567656A discloses an impeller detection device, which is equipped with a position detection unit (equivalent to the scanner in this invention) and includes a display device for the degree of the position detection unit. The display device is connected to a magnetic grating ruler or optical grating ruler through a control unit to accurately display the value measured by the magnetic grating ruler or optical grating ruler. Finally, the qualified and unqualified are transported out through a transfer mechanism.

[0038] Example 2

[0039] Based on Example 1, please refer to Figure 4 As shown, the limiting mechanism 8 includes a cylinder 81 fixedly installed in the gap. A push plate 82 is fixedly installed on the piston rod of the cylinder 81. Two inclined racks 83 of different lengths are provided on both sides of the push plate 82. Because the blades of the impeller 2 are not symmetrically arranged, racks 83 of different lengths are provided, and their angles can also be adjusted appropriately. The racks 83 and gears 84 are rotatably installed on both sides of the inner wall of the conveyor frame 1. The conveyor frame 1 is provided with a slot for placing the gear 84, the rotating shaft 85 and the baffle 86. When the baffle 86 is not needed, it can be stored in the slot to avoid occupying space. The rotating shaft 85 is fixedly installed on the top of the gear 84, and the baffle 86 is fixedly installed on the outside of the rotating shaft 85. The two baffles 86 are used to block the two blades of the impeller 2.

[0040] Start cylinder 81, push push plate 82 to move, which in turn pushes rack 83, which in turn drives gear 84 to rotate, which in turn drives rotating shaft 85 to rotate, rotating shaft 85 drives baffle 86 to rotate, which in turn blocks and limits the two blades of impeller 2.

[0041] Example 3

[0042] Based on Example 1, please refer to Figure 5 As shown, the transfer mechanism 7 includes two vertically mounted side plates 71. A cylinder 73 is vertically mounted on the outer side of each side plate 71. A lifting plate 72 is fixedly mounted on the piston rod of each cylinder 73. A horizontally mounted servo motor is fixedly mounted on one side of the lifting plate 72. A lead screw is fixedly mounted on the output shaft of the servo motor. A moving plate 74 is connected to the lead screw via a threaded sleeve. An adjusting motor 75 is fixedly mounted on the top of the moving plate 74. The output shaft of the adjusting motor 75 passes through the moving plate 74 and connects to a rotating plate 76. A mounting plate 77 is connected to the bottom of the rotating plate 76 via a connecting rod. A suction cup 710 is provided on the mounting plate 77.

[0043] Two symmetrical inclined grooves 78 are provided on one side of the mounting plate 77, and a horizontal groove 713 is provided in the middle of the mounting plate 77. Two opposite movable plates 711 are slidably provided on the other side of the mounting plate 77 by bolts. A central groove 712 is provided on the movable plates 711. The movable plates 711 are slidable and then locked by bolts, thereby controlling the position of the suction cup. Locking bolts 79 are provided on the two inclined grooves 78, the horizontal groove 713 and the movable plates 711. The suction cup 710 is fixedly installed at the bottom of the locking bolts 79. By tightening the bolts 79, the suction cup 710 can be moved in the inclined grooves 78 and the horizontal grooves 713, thereby adapting to different types of impellers.

[0044] When the impeller 2 moves below the transfer mechanism 7, the drive suction cup is raised and lowered and moved left and right to hold the impeller 2. Then the adjustment motor 75 is started to drive the rotating plate 76 to rotate, which in turn drives the mounting plate 77 to rotate, thereby separating the qualified and unqualified impellers 2 for conveying.

[0045] Example 4

[0046] Based on Example 1, please refer to Figure 6-7As shown, the clamping mechanism 9 includes a cylinder 11 91 vertically mounted on the gap of the conveyor frame 1. A drive motor 92 is fixedly mounted on the piston rod of the cylinder 11 91. A rotating shaft 97 is fixedly mounted on the output shaft of the drive motor 92. A threaded push sleeve 93 is threadedly connected to the rotating shaft 97. Only the part of the rotating shaft 97 that contacts the threaded push sleeve 93 is threaded to facilitate the movement of the threaded push sleeve 93. A push plate 94 is fixedly mounted on the end of the threaded push sleeve 93. The push plate 94 is slidably connected to the rotating shaft 97. One end of the push plate 94 is arranged in a circular array. Multiple push rods 98 are provided, which pass through the support sleeve plate 99 and are fixedly connected to multiple trapezoidal frustums 911, so as to facilitate the movement of the trapezoidal frustums 911. There are two support sleeve plates 99, and two trapezoidal frustums 911 are equally spaced between the two support sleeve plates 99. The support sleeve plate 99 is sleeved on the rotating shaft 97, and multiple springs 910 are installed on the support sleeve plate 99 in a circumferential array. The end of the spring 910 is connected to one end of the rubber plate 913. The outer circumferential surface of the support sleeve plate 99 is also connected to the arc plate 95 through the connecting rod.

[0047] The outer circumferential surface of the trapezoidal frustum 911 is provided with multiple sliding grooves arranged in a circular array. Trapezoidal inclined blocks 912 are slidably connected in the sliding grooves. Two rubber plates 913 are symmetrically installed on one side of the trapezoidal inclined blocks 912. Through the arrangement of the trapezoidal inclined blocks 912, the three rubber plates 913 can be connected as a whole for synchronous movement. At the same time, the outer circumferential surface of the trapezoidal frustum 911 is also provided with an outer sleeve plate 914 adapted to the trapezoidal frustum 911. An arc plate 95 is fixedly installed on the outer sleeve plate 914. A rubber plate 913 is arranged between every two arc plates 95. An end plate 96 is provided at the end of the arc plate 95. The rotating shaft 97 passes through the support sleeve plate 99, the trapezoidal frustum 911 and the end plate 96 and is rotatably connected.

[0048] When the impeller moves above the clamping mechanism 9, the limiting mechanism 8 limits its position to ensure more accurate positioning. The cylinder 11 91 is activated, pushing the clamping mechanism 9 into the center hole of the impeller. Then, the drive motor 92 is activated to drive the rotating shaft 97 to rotate. The rotating shaft 97 drives the threaded push sleeve 93 to move, which in turn pushes the push plate 94 to move. The push plate 94 pushes the trapezoidal frustum 911 to move through the push rod 98. The trapezoidal frustum 911 pushes the trapezoidal inclined block 912 to move, which in turn pushes the rubber plate 913 to move, clamping the impeller from the inside and then driving it to rise, facilitating the flipping mechanism to clamp and flip it, and also facilitating scanning by the scanner. Conversely, the trapezoidal frustum 911 resets, and the rubber plate 913 is reset by the spring. This structure is also suitable for different types of impellers.

[0049] Please see Figure 8As shown, the three-dimensional adjustment structure 3 includes two vertically arranged side plates 31. A vertically arranged cylinder 32 is fixedly installed on the outer side of each side plate 31. A lifting plate 33 is fixedly installed on the piston rod of the cylinder 32. A cylinder 35 is installed at the bottom of the lifting plate 33. A cylinder 34 perpendicular to the piston rod of the cylinder 35 is provided at its end. A scanner 4 is fixedly installed on the piston rod of the cylinder 34. The arrangement of multiple cylinders facilitates the adjustment of the scanner 4's position, resulting in clearer scanning and easier use.
