Description

Technical Field

[0001] This invention belongs to the field of centrifugal pump parts processing technology, specifically relating to a centrifugal pump impeller cover plate processing device. Background Technology

[0002] Centrifugal pump impellers typically consist of blades and front and rear cover plates. The impeller cover plates are divided into front and rear cover plates. The front cover plate is located on the impeller inlet side, and its main function is to form a flow channel together with the rear cover plate to guide the liquid flow inside the impeller and reduce liquid leakage loss. The rear cover plate is located on the impeller outlet side, and together with the front cover plate, it supports the blades to ensure the structural stability of the impeller when rotating at high speed. At the same time, the rear cover plate also helps to improve the hydraulic efficiency of the impeller.

[0003] In existing technologies, deburring methods for metal impeller covers typically include manual deburring, mechanical deburring, chemical deburring, electrolytic deburring, and ultrasonic deburring. For centrifugal pump impeller covers with complex internal shapes, ultrasonic technology is usually used for deburring. In practical applications, the impeller cover to be deburred is usually placed in an ultrasonic treatment device for static treatment, where the ultrasonic vibration removes the burrs. Although this method can effectively remove the burrs from the impeller cover, the operation of placing and removing the impeller cover into the ultrasonic treatment device is inconvenient and has poor continuity. In addition, when the impeller cover is placed in the ultrasonic deburring device, some tiny particles that have broken off from the burrs may remain on the surface of the impeller cover. The static treatment method increases the possibility of these tiny particles remaining, thus greatly increasing the difficulty of rinsing after ultrasonic deburring.

[0004] Therefore, a centrifugal pump impeller cover plate processing device is needed to solve the problems of poor continuity of deburring operation and easy residue of small particles when using ultrasonic vibration to deburr centrifugal pump impeller cover plates in the existing technology. Summary of the Invention

[0015] A sealing sleeve is provided on the periphery of the balance bar and fixed to the bottom end of the fixed sleeve. The sealing sleeve has a sealing ring that is tightly fitted to the outer surface of the balance bar. The outer surface of the balance bar has a balance spring that is fixed to both the sealing ring and the fixed sleeve.

[0016] A fixed track ring is fixed to the bottom inner wall of the ultrasonic treatment box. The bottom end of the balance bar extends into the interior of the fixed track ring. The inner wall of the fixed track ring is provided with multiple protrusions distributed at equal angles.

[0017] It is further worth noting that the lifting mechanism includes:

[0018] The bottom end of the T-shaped rod is rotatably connected to the top end of the spherical fixed column. A fixed sleeve is slidably fitted on the top outer surface of the T-shaped rod, and the fixed sleeve is detachably connected to the output end of the electric push rod.

[0019] A rotating block is disposed inside the fixed sleeve and its top surface is fitted against the output end of the electric push rod. A retaining spring is fixed to the opposite surface of the T-shaped rod and the rotating block.

[0020] Furthermore, it should be noted that the supply and transfer mechanism includes:

[0021] Two L-shaped rack rods are provided and both slide through the side wall of the ultrasonic treatment box. A rotating gear is fastened to the outer surface of the docking column. Both L-shaped rack rods are meshed with the rotating gear. A tension spring is provided on the outer surface of the L-shaped rack rod and fixed to the L-shaped rack rod and the outer surface of the ultrasonic treatment box.

[0022] The pressing sleeve is fastened to the outer surface of the fixed sleeve. Both ends of the pressing sleeve are fixed with L-shaped rods. The outer surface of the ultrasonic treatment box is provided with pressing blocks that are fixed to the L-shaped rods. The pressing blocks are inclined and fit against the outer surface of the end of the L-shaped rack rod.

[0023] In a preferred embodiment, mounting plates are fixed to the inner walls of both ends of the ultrasonic treatment box, and two vertically distributed limiting rods are fixed to the opposite surfaces of the two mounting plates. The L-shaped rack is slidably disposed on the opposite surfaces of the two limiting rods located at the same end.

[0024] In a preferred embodiment, the compression mechanism includes:

[0025] Compression plates are provided in two and are respectively attached to the top opposite surfaces of the partition and the ultrasonic treatment box. A pressing rod is fixed between the compression plates and the adjacent L-shaped rods.

[0026] The liquid inlet channel is located on the top outer surface of the partition and below the compression plate. The bottom top surface of the partition has multiple evenly distributed through holes.

[0027] In a preferred embodiment, a receiving plate is fixed on both outer surfaces of the ultrasonic treatment box, and the outer end face of the receiving plate is fitted to one end of the outer surface of the pressing block.

[0028] Compared with the prior art, the centrifugal pump impeller cover plate processing device provided by the present invention has at least the following beneficial effects:

[0029] (1) Through the drive of the electric push rod and the mutual cooperation between the lifting mechanism, the fastening mechanism and the supply and rotation mechanism, the centrifugal pump impeller cover plate can be placed and installed in sequence, the placement plate is submerged in the liquid surface and fastened and positioned, the reciprocating rotation ultrasonic vibration deburring and the upward lifting and picking of materials can be carried out in sequence, realizing the semi-automatic ultrasonic deburring treatment of the centrifugal pump impeller cover plate, which greatly improves the connection between the feeding, ultrasonic vibration deburring and picking operations of the centrifugal pump impeller cover plate. At the same time, the reciprocating rotation ultrasonic vibration deburring treatment of the centrifugal pump impeller cover plate, compared with the centrifugal pump impeller cover plate being placed in the ultrasonic treatment box for ultrasonic vibration deburring treatment, greatly reduces the possibility of small particles remaining inside the centrifugal pump impeller cover plate, and greatly reduces the difficulty of subsequent rinsing treatment.

[0030] (2) The compression mechanism is set up to move synchronously with the supply and transfer mechanism, so as to spray the liquid under the placement plate obliquely upward, further improving the liquid flow in the ultrasonic treatment box. Combined with the reciprocating rotation of the placement plate in the ultrasonic treatment box, it further avoids the possibility of small particles remaining inside the centrifugal pump impeller cover plate.

[0031] (3) The setting of the balancing component can not only ensure the stability of the placement plate during the reciprocating rotation process, but also allow the placement plate to deflect on the surface of the spherical fixed column through the intermittent contact between the balance bar and the protrusion. That is, the centrifugal pump impeller cover plate undergoes reciprocating deflection and rotation processing in the ultrasonic treatment box, which reduces the possibility of small particles remaining inside the centrifugal pump impeller cover plate to a certain extent.

[0042] The present invention will be further described below with reference to embodiments.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0044] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by a person skilled in the art to which this disclosure pertains. The words “comprising” or “including” and similar terms used in this disclosure mean that the element or object preceding the word covers the element or object listed after the word and its equivalents, without excluding other elements or objects. The words “connected” or “linked” and similar terms are not limited to physical or mechanical connections, but may also include electrical connections, whether direct or indirect. “Up,” “down,” “left,” “right,” etc., are used only to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0045] Example 1:

[0046] Please see Figure 1-9 The present invention provides a centrifugal pump impeller cover plate processing device, including an ultrasonic treatment box 1 and a spherical bracket 2. The spherical bracket 2 is fixed at the center of the bottom inner wall of the ultrasonic treatment box 1. A placement plate 3 is provided above the spherical bracket 2. A fastening mechanism 4 is provided between the placement plate 3 and the spherical bracket 2.

[0047] Mounting bracket 5 is fixed to the top surface of the end of the ultrasonic treatment box 1. An electric push rod 6 is fixed to the top and bottom surfaces of the mounting bracket 5. A lifting mechanism 7 is provided between the electric push rod 6 and the placement plate 3. A power supply mechanism 8 that cooperates with the lifting mechanism 7 is provided below the placement plate 3.

[0048] It should be noted that, through the cooperation of the electric push rod 6 and the lifting mechanism 7, the placement plate 3 can be lifted up and down in the ultrasonic treatment box 1. When performing ultrasonic deburring on the centrifugal pump impeller cover plate, the placement plate 3 is first lifted by the electric push rod 6 and the lifting mechanism 7, so that the height of the placement plate 3 is higher than the top surface of the ultrasonic treatment box 1. Then, multiple centrifugal pump impeller cover plates are placed in the slots on the placement plate 3 in sequence, thereby completing the positioning and placement of multiple centrifugal pump impeller cover plates.

[0049] The placement plate 3, which has been placed with centrifugal pump impeller cover plates, is moved down by the electric push rod 6 and the lifting mechanism 7 until the bottom of the placement plate 3 is fastened to the ball seat 2 by the fastening mechanism 4. At this time, multiple centrifugal pump impeller cover plates are submerged below the liquid surface inside the ultrasonic treatment box 1, thus completing the preparation work for ultrasonic deburring of the centrifugal pump impeller cover plates.

[0050] By activating the ultrasonic generator in the ultrasonic treatment chamber 1, the vibration energy generated by the ultrasonic waves is used to perform ultrasonic vibration deburring on the centrifugal pump impeller cover plate located below the liquid surface. At the same time, the electric push rod 6 is pressed down again. Since the fastening mechanism 4 and the ball seat 2 are fastened and positioned, the placement plate 3 does not cover at the height of the ultrasonic waves. At this time, the lifting mechanism 7 rebounds in the opposite direction, and the supply and rotation mechanism 8 moves synchronously, so that the placement plate 3 rotates in the ultrasonic treatment chamber 1. This completes the rotary ultrasonic vibration deburring of multiple centrifugal pump impeller covers. By driving the lifting mechanism 7 to reciprocate through the electric push rod 6, the placement plate 3 and the centrifugal pump impeller cover plate above the placement plate 3 can reciprocate and rotate, thereby effectively reducing the possibility of residual microparticles after ultrasonic vibration deburring.

[0051] When the ultrasonic vibration deburring process of the centrifugal pump impeller cover plate is completed, the electric push rod 6 drives the lifting mechanism 7 to move upward until the fastening mechanism 4 separates from the ball seat 2. At this time, the placement plate 3 and the centrifugal pump impeller cover plate located above the placement plate 3 are lifted from the liquid in the ultrasonic treatment box 1 through the connection of the lifting mechanism 7. Then the centrifugal pump impeller cover plate is taken out from the placement plate 3 and transferred to the subsequent rinsing device for rinsing.

[0052] Two partitions 9 are provided and are symmetrically fixed to the bottom inner wall of the ultrasonic treatment box 1. A compression mechanism 10 that cooperates with the supply and transfer mechanism 8 is provided inside the partition 9.

[0053] It should be noted that the compression mechanism 10 moves synchronously with the supply and transfer mechanism 8, thereby causing the partition 9 to reciprocate and compress the liquid in the ultrasonic treatment box 1, thereby compressing the liquid below the placement plate 3, further improving the flow performance of the liquid in the ultrasonic treatment box 1, further avoiding the possibility of small particles remaining on the centrifugal pump impeller cover plate, and effectively reducing the difficulty of subsequent rinsing.

[0054] Further as Figure 2 , Figure 4 , Figure 7 and Figure 9 As shown, it is worth noting that the fastening mechanism 4 includes a docking post 41, which is detachably mounted on the inner wall of the spherical card holder 2, and a spherical fixing post 42 is fixed on the top surface of the docking post 41.

[0055] A spherical collar 43 is fixedly embedded in the inner wall of the center of the placement plate 3. The spherical collar 43 is rotatably sleeved on the outer surface of the spherical fixed column 42. A balancing component 44 that cooperates with the placement plate 3 is provided around the spherical card seat 2.

[0056] It should be noted that by setting the balancing component 44, the spherical collar 43 can be stably fitted onto the outer surface of the spherical fixing post 42, thereby improving the stability of the placement plate 3.

[0057] It should be noted that, through the downward drive of the electric push rod 6 and the connecting action of the lifting mechanism 7, the docking column 41 below the placement plate 3 is elastically squeezed and fastened to the ball seat 2, so that the placement plate 3 and the centrifugal pump impeller cover plate located above the placement plate 3 are submerged below the liquid surface in the ultrasonic treatment box 1, thereby completing the fastening and installation of the placement plate 3, and at the same time, it is stably located in the ultrasonic treatment box 1 by the balancing component 44.

[0058] When the centrifugal pump impeller cover is deburred by ultrasonic vibration, the electric push rod 6 drives the lifting mechanism 7 to move downward and then to reset upward, thus forming a reciprocating motion of the lifting mechanism 7 moving downward and upward. At this time, the balance component 44 moves synchronously with the supply and rotation mechanism 8, thereby ensuring the balance and stability of the placement plate 3 when it rotates through the supply and rotation mechanism 8.

[0059] Further as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, it is worth noting that the lifting mechanism 7 includes a T-shaped rod 71. The bottom end of the T-shaped rod 71 is rotatably connected to the top end of the spherical fixed column 42. A fixed sleeve 72 is slidably sleeved on the top outer surface of the T-shaped rod 71. The fixed sleeve 72 is detachably connected to the output end of the electric push rod 6.

[0060] Rotating block 73 is disposed inside the fixed sleeve 72 and its top surface is fitted with the output end of the electric push rod 6. A clamping spring 74 is fixed on the opposite surface of the T-shaped rod 71 and the rotating block 73.

[0061] It should be noted that, through the elastic force of the clamping spring 74, the top of the T-shaped rod 71 is located at the bottom of the fixed sleeve 72. At this time, when the electric push rod 6 drives the fixed sleeve 72, the T-shaped rod 71 and the placement plate 3 to move downward, the docking post 41 and the ball-shaped card seat 2 perform elastic compression and fastening, so that the placement plate 3 can be fastened and installed inside the ultrasonic treatment box 1.

[0062] When the electric push rod 6 moves down again, the height of the placement plate 3 does not change due to the interlocking action of the docking post 41 and the ball seat 2. At this time, the T-shaped rod 71 compresses the spring 74 in the opposite direction, thereby forming a fixed sleeve 72 whose height above the ultrasonic treatment box 1 changes due to the drive of the electric push rod 6.

[0063] Further as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 9 As shown, it is worth noting that the supply and transfer mechanism 8 includes an L-shaped rack 81. There are two L-shaped racks 81, both of which slide through the side wall of the ultrasonic treatment box 1. A rotating gear 82 is fastened to the outer surface of the docking column 41. Both L-shaped racks 81 are meshed with the rotating gear 82. A tension spring 83 is provided on the outer surface of the L-shaped rack 81 and fixed to the L-shaped rack 81 and the outer surface of the ultrasonic treatment box 1.

[0064] Pressing sleeve 84 is fastened to the outer surface of fixed sleeve 72. Both ends of pressing sleeve 84 are fixed with L-shaped rods 85. The outer surface of ultrasonic treatment box 1 is provided with pressing block 86 fixed to L-shaped rod 85. Pressing block 86 is set to be inclined to fit the outer surface of the end of L-shaped rack rod 81.

[0065] The inner walls of both ends of the ultrasonic treatment box 1 are fixed with mounting plates 11. Two vertically distributed limiting rods 12 are fixed on the opposite surfaces of the two mounting plates 11. The L-shaped rack rod 81 is slidably disposed on the opposite surfaces of the two limiting rods 12 located at the same end.

[0066] It should be noted that the mounting plate 11 is equipped with an ultrasonic generator and corresponding electrical components for generating ultrasonic waves in the ultrasonic processing box 1. This is a standard feature in the field and will not be described in detail here. In addition, the setting of the limit rod 12 can further improve the movement stability of the L-shaped rack rod 81.

[0067] It should be noted that after the placement plate 3 is fastened and positioned by the fastening mechanism 4, the fixing sleeve 72 moves downward again with the electric push rod 6, and at the same time drives the pressing sleeve rod 84, L-shaped rod 85 and pressing block 86 to press down synchronously. At this time, through the inclined surface squeezing action of the pressing block 86 and the end of the L-shaped rack rod 81, the L-shaped rack rods 81 at both ends move towards the outside of the ultrasonic treatment box 1, and at the same time drive the tension spring 83 to stretch. Through the meshing transmission action of the L-shaped rack rod 81 and the rotating gear 82, and through the rotation limit action of the docking column 41 and the ball seat 2, the docking column 41, the balance part 44, the ball fixing column 42, the ball collar 43 and the placement plate 3 all rotate synchronously, thus completing the rotational ultrasonic vibration deburring treatment of the centrifugal pump impeller cover plate on the placement plate 3.

[0068] After the electric push rod 6 drives the fixed sleeve 72 to move down again, and then the electric push rod 6 drives the fixed sleeve 72 to move up and reset, it can drive the pressing block 86 to reset. At this time, through the elastic force of the tension spring 83, the L-shaped rack rod 81 is reset. Through the meshing transmission between the L-shaped rack rod 81 and the rotating gear 82, the placement plate 3 can be rotated and reset. Thus, when the electric push rod 6 drives the fixed sleeve 72 to move down and up in a reciprocating drive, the placement plate 3 is reciprocated in the ultrasonic treatment box 1, completing the reciprocating rotation ultrasonic vibration deburring treatment of the centrifugal pump impeller cover plate.

[0069] It should be noted that the L-shaped rack rod 81 is provided with a connecting protrusion at the corner for the tension spring 83 to connect, and the contact part between the protrusion and the pressing block 86 is set at an angle.

[0070] Further as Figure 2 , Figure 3 , Figure 6 and Figure 9 As shown, it is worth noting that the compression mechanism 10 includes a compression plate 101. Two compression plates 101 are provided and are respectively attached to the top opposite surfaces of the partition 9 and the ultrasonic treatment box 1. A pressing rod 102 is fixed between the compression plate 101 and the adjacent L-shaped rod 85.

[0071] The liquid inlet channel 103 is opened on the top outer surface of the partition 9 and located below the compression plate 101. The bottom top surface of the partition 9 has a plurality of evenly distributed through holes 104.

[0072] It should be noted that, with the liquid inlet channel 103 and through hole 104, the space formed between the partition 9 and the ultrasonic treatment box 1 is filled with liquid. When the fixed sleeve 72 moves down again with the electric push rod 6, the compression plate 101 is pressed down with the L-shaped rod 85 through the connection of the pressing plate until the compression plate 101 reaches below the liquid inlet channel 103. At this time, the compression plate 101 compresses the liquid in the partition 9 and the ultrasonic treatment box 1 and sprays it out under pressure through the through hole 104, thereby forming an upward oblique spray of the liquid below the placement plate 3, further improving the liquid flow in the ultrasonic treatment box 1. Combined with the reciprocating rotation of the placement plate 3 in the ultrasonic treatment box 1, this further avoids the possibility of small particles remaining inside the centrifugal pump impeller cover.

[0073] Further as Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, it is worth noting that both outer surfaces of the ultrasonic treatment box 1 are fixed with receiving plates 13, and the outer end face of the receiving plate 13 is fitted to one end of the outer surface of the pressing block 86.

[0074] It should be noted that the receiving plate 13 can be used for the initial placement of the centrifugal pump impeller cover plate and temporary storage after deburring, and can also improve the stability of the pressing block 86 moving up and down with the L-shaped rod 85.

[0075] This embodiment has the following working process: When deburring multiple centrifugal pump impeller cover plates, the placement plate 3 is first moved to the top of the ultrasonic treatment box 1 by the connection between the electric push rod 6 and the lifting mechanism 7. Then, the centrifugal pump impeller cover plates are placed and installed in sequence to complete the positioning and installation of multiple centrifugal pump impeller cover plates.

[0076] Driven downward by the electric push rod 6 and connected by the lifting mechanism 7, the mating column 41 in the fastening mechanism 4 and the ball seat 2 are elastically squeezed and fastened, thereby completing the placement plate 3 being fully submerged below the liquid surface of the ultrasonic treatment box 1.

[0077] By reciprocating the downward movement and upward movement of the electric push rod 6, the placement plate 3 can be rotated synchronously with the supply and transfer mechanism 8, thereby causing the placement plate 3 and the centrifugal pump impeller cover plate located on the placement plate 3 to undergo reciprocating rotation. Compared with the centrifugal pump impeller cover plate being placed in the ultrasonic treatment box 1 for ultrasonic vibration deburring, this greatly reduces the possibility of small particles remaining inside the centrifugal pump impeller cover plate, and greatly reduces the difficulty of subsequent rinsing.

[0078] After the centrifugal pump impeller cover plate is thoroughly deburred, the electric push rod 6 drives it upward and the lifting mechanism 7 connects it until the docking column 41 in the fastening mechanism 4 below the placement plate 3 separates from the ball seat 2, thus forming the upward discharge process of the centrifugal pump impeller cover plate. Then the centrifugal pump impeller cover plate is taken out from the placement plate 3 and transferred to the subsequent flushing device, thus completing the ultrasonic deburring process of the centrifugal pump impeller cover plate.

[0079] Example 2:

[0080] Based on Example 1, according to Figure 3 , Figure 7 and Figure 9 As shown, it is worth noting that the balancing component 44 includes a fixed sleeve rod 441, which is fixed to the bottom outer surface of the docking column 41. The top surface of the end of the fixed sleeve rod 441 slides through a balancing rod 442, and the top of the balancing rod 442 is hinged to the bottom surface of the placement plate 3.

[0081] A sealing sleeve 443 is disposed around the balance bar 442 and fixed to the bottom end of the fixed sleeve 441. A sealing ring 444 is provided inside the sealing sleeve 443 and is tightly fitted to the outer surface of the balance bar 442. A balance spring 445 is provided on the outer surface of the balance bar 442 and is fixed to the opposite surfaces of the sealing ring 444 and the fixed sleeve 441.

[0082] The fixed track ring 446 is fixed to the bottom inner wall of the ultrasonic treatment box 1. The bottom end of the balance rod 442 extends into the interior of the fixed track ring 446. The inner wall of the track of the fixed track ring 446 is provided with a plurality of protrusions 447 distributed at equal angles.

[0083] It should be noted that when the docking column 41 rotates, the spherical fixing column 42, the fixing sleeve rod 441, and the balance rod 442 rotate synchronously. When the bottom end of the balance rod 442 contacts the protrusion 447, the balance rod 442 moves upward within the fixing sleeve rod 441, causing the placement plate 3 to deflect on the surface of the spherical fixing column 42 through the spherical collar 43. That is, the centrifugal pump impeller cover plate undergoes reciprocating deflection and rotation treatment within the ultrasonic treatment box 1, which reduces the possibility of microparticles remaining inside the centrifugal pump impeller cover plate to a certain extent.

[0084] In summary, based on the two embodiments, it can be seen that through the driving of the electric push rod 6 and the mutual cooperation between the lifting mechanism 7, the fastening mechanism 4, and the supply and rotation mechanism 8, the centrifugal pump impeller cover plate can be sequentially placed and installed, the placement plate 3 can be submerged in the liquid surface and fastened and positioned, the reciprocating rotation ultrasonic vibration deburring and the upward lifting and material removal can be carried out sequentially. This achieves semi-automatic ultrasonic deburring of the centrifugal pump impeller cover plate, which greatly improves the connection between the material feeding, ultrasonic vibration deburring and material removal operations of the centrifugal pump impeller cover plate. At the same time, the reciprocating rotation ultrasonic vibration deburring of the centrifugal pump impeller cover plate, compared with the centrifugal pump impeller cover plate being placed in the ultrasonic treatment box 1 for ultrasonic vibration deburring, greatly reduces the possibility of small particles remaining inside the centrifugal pump impeller cover plate, and greatly reduces the difficulty of subsequent rinsing.

[0085] The compression mechanism 10 is set up to move synchronously with the supply and transfer mechanism 8, forming an oblique upward spray of the liquid below the placement plate 3, which further improves the liquid flow in the ultrasonic treatment box 1. Combined with the reciprocating rotation of the placement plate 3 in the ultrasonic treatment box 1, it further avoids the possibility of small particles remaining inside the centrifugal pump impeller cover plate.

[0086] The setting of the balancing component 44 can not only ensure the stability of the placement plate 3 during reciprocating rotation, but also allow the placement plate 3 to deflect on the surface of the spherical fixed column 42 through the intermittent contact between the balancing rod 442 and the protrusion 447. That is, the centrifugal pump impeller cover plate undergoes reciprocating deflection and rotation treatment in the ultrasonic treatment box 1, which reduces the possibility of small particles remaining inside the centrifugal pump impeller cover plate to a certain extent.

[0087] The electric actuator 6 can be commercially available and equipped with a separate power supply. This is a mature technology in the field and has been fully disclosed, so it will not be repeated in the specification.

[0088] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art. The general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
