Description

Technical Field

[0001] This utility model relates to the field of balance disc assembly equipment, specifically an assembly device for a centrifugal pump balance disc. Background Technology

[0002] The balance disc is one of the key components of a centrifugal pump. Its working principle is to use the axial thrust generated by the pressure difference of the gas on both sides to counteract the axial force of the rotor.

[0003] When fluid enters the pump chamber, it generates axial force. If this force is not effectively balanced, it will cause impeller displacement and reduced flow. In severe cases, it will cause friction between the impeller and the pump body, affecting the stable operation and lifespan of the centrifugal pump.

[0004] By installing a balance disc, axial force can be effectively reduced, enabling the centrifugal pump to operate stably and extending its service life.

[0005] The balance disc consists of an upper disc and a lower disc. The assembly steps are as follows: press the sealing ring into the upper disc, and then rotate the upper disc 180 degrees to press it together with the lower disc.

[0006] The manual assembly process is quite cumbersome. The sealing ring needs to be manually pressed into the hole of the upper plate using a specific tool, and then the upper plate is rotated 180 degrees and pressed into the inner hole of the lower plate. During the pressing process, attention must be paid to the balance of force, otherwise it will affect the quality of the balance. Therefore, the manual assembly of the balance plate will result in cumbersome work and low work efficiency. At the same time, due to improper pressing operation by workers, the balance plates produced will have poor consistency and unstable quality, resulting in failure to meet the requirements of dynamic balance.

[0007] The existing CN 216895085 U - A centrifugal pump balance disc structure only discloses the structural features of the balance disc, but does not disclose how to assemble the balance disc.

The other end of the long shaft 506 is connected to the pressure block 509 fixing plate 104. The pressure block 509 is set at the lower part of the pressure block 509 fixing plate 104. The third cylinder mounting plate and the fourth cylinder mounting plate are set on the support plate 401.

[0081] The platform structure 600 includes a tooling platform 601, a rotary cylinder, a rotary platform 603, a first positioning component 605, and a second positioning component 604. The tooling platform 601 is mounted on the left folding plate 109 and the right folding plate 102. The two second positioning components 604 are mounted on the rotary platform 603 and are on the same straight line. The rotary platform 603 is located at the output end of the rotary cylinder. The first positioning component 605 is located on the tooling platform 601 and is located directly below the pressure block 509.

[0082] Working principle: The upper plate is placed on the first positioning component 605 and fixed. The two lower plates are placed on the two second positioning components 604 respectively. The sealing ring is placed in the inner hole of the upper plate. The compression cylinder 501 is activated, and the compression cylinder 501 extends, driving the long shaft 506 to move downward, so that the pressure block 509 acts on the upper surface of the sealing ring and presses the sealing ring into the inner hole of the upper plate. After this action is completed, the cylinder retracts and returns to its original position.

[0083] When the motor operates and rotates forward, it drives the lead screw, which in turn drives the guide block 317 downward. This causes the Y-direction moving plate component 305, mounted on the guide block 317, to move the clamping and tilting assembly 400 downward. Consequently, the clamping block 404 moves downward to the outer side of the upper plate, and the clamping cylinder 403 operates, causing the two clamping blocks 404 to clamp the upper plate. Subsequently, the motor reverses, causing the clamping and tilting assembly 400 to move upward. Then, the rotary cylinder 402 operates and rotates 180 degrees, driving the drive pulley 409. This drives the driven pulley 416 via the belt 419, causing the rotary output component 406 to rotate 180 degrees. This results in the upper plate rotating 180 degrees along with the clamping block 404. Then, the first push cylinder 209 operates, extending the horizontal push plate 207 to move the second adjusting component 300 to the left. When the adjusting component 300 moves to the left and reaches the proximity switch on the left, the second adjusting component 300 stops. At this time, the upper plate moves to directly above the lower plate, the motor rotates forward, and the clamping block 404 moves the upper plate downward until the lower part of the upper plate is set at the upper end of the inner hole of the lower plate. The clamping block 404 is released, the squeezing cylinder 501 works, the squeezing cylinder 501 extends, driving the long shaft 506 to move downward, so that the pressure block 509 acts on the upper surface of the upper plate and presses the upper plate into the inner hole of the lower plate. At this time, the balance disc is assembled. The squeezing cylinder 501 retracts, the pressure block 509 returns to its original position, the first pushing cylinder 209 retracts, driving the second adjusting component 300 to move to the right and return to its original position. The rotating cylinder works, rotating 180 degrees, and removes the assembled balance disc from the first positioning component 605, and continues to repeat the previous action.

[0084] Obviously, the specific implementation of this utility model is not limited to the above-mentioned methods. Any non-substantial improvements made using the inventive concept and technical solution of this utility model are within the protection scope of this utility model.
