Description

Technical Field

[0001] The utility model relates to the technical field of rotor pumps, in particular to a rotor with adjustable rotor tips. Background Technique

[0002] A rotor pump refers to a pump that changes the working volume through the relative movement between the rotor and the pump body, thereby increasing the energy of the liquid. A rotor pump is a rotary positive-displacement pump with a positive displacement property, and its flow rate does not change with the back pressure. Among them, the rotor is one of the key components, and its dimensional accuracy has an important impact on the performance and service life of the equipment.

[0003] However, in actual applications, after the rotor has been used and worn for a long time, its outer diameter often becomes smaller, resulting in a decline in equipment performance and even causing failures. Most traditional rotor adjustment methods involve replacing the new rotor, which greatly increases the maintenance cost of the equipment. Therefore, we propose a rotor with adjustable rotor tips to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that the traditional rotor adjustment method increases the maintenance cost of the equipment by replacing the new rotor in the prior art, and to propose a rotor with adjustable rotor tips.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A rotor with adjustable rotor tips includes a rotor body. Four grooves are equidistantly arranged on the rotor body. A plurality of fixing holes are arranged on the bottom inner walls of the four grooves. Two groups of limiting holes are arranged on both sides of the plurality of fixing holes on the bottom inner walls of the four grooves, and the number of each group of limiting holes is at least three. Threads are provided on the inner walls of the fixing holes and the limiting holes. The rotor further includes:

[0007] Four adjustment components are respectively arranged in the corresponding grooves and are used to adjust the outer diameter size of the rotor body after the rotor body has been used for a long time;

[0008] Four limiting components are arranged in the corresponding grooves, and the limiting components are located between the adjustment components and the bottom inner walls of the grooves and are used to cooperate with the adjustment components to make the adjustment components restore to the original size of the rotor body.

[0009] In a possible design, the adjustment component includes a rotor tip movable block, and the rotor tip movable block is slidably connected to the inner walls of both sides of the corresponding groove.

[0010] In a possible design, a plurality of first through holes corresponding to the fixing holes are formed in the rotor tip movable block, and first bolts are arranged in the first through holes. The first bolts are threadedly connected to the corresponding fixing holes, so that the rotor tip movable block is fixed to the rotor body.

[0011] In a possible design, the limiting component includes two adjusting blocks. Both adjusting blocks are slidably connected to the inner walls on both sides of the corresponding groove, and the tops of the two adjusting blocks abut against the bottom of the rotor tip movable block.

[0012] In a possible design, second through holes are formed in both adjusting blocks, and second bolts are arranged in the second through holes. The second bolts are threadedly connected to the corresponding limiting holes for fixing when the adjusting blocks are adjusted to different positions.

[0013] In a possible design, the sides of the rotor tip movable block and the adjusting block that are close to each other are both provided as inclined surfaces for adjusting the distance between the rotor tip movable block and the inner wall of the bottom of the groove when the position of the adjusting block changes, so as to change the outer diameter size of the rotor body.

[0014] First, four grooves are equidistantly formed on the rotor body. Fixing holes and limiting holes are formed in the inner wall of the bottom of the groove. The adjusting component includes a rotor tip movable block. The rotor tip movable block is slidably connected to the inner walls on both sides of the groove and is connected to the fixing hole through a first bolt to realize fixation with the rotor body. The limiting component includes two adjusting blocks. The adjusting blocks are also slidably connected to the inner walls on both sides of the groove and are connected to the limiting hole through a second bolt to realize position fixation.

[0015] During the use of the rotor, if the rotor tip is worn and the outer diameter decreases, by loosening the first bolt, the rotor tip movable block is separated from the rotor body. Then, according to the wear degree of the rotor tip, the positions of the two adjusting blocks are adjusted. The positions of the two adjusting blocks are changed by using the second through hole to be threadedly connected to the corresponding limiting hole through the second thread. Since the sides of the rotor tip movable block and the adjusting block that are close to each other are both provided as inclined surfaces, after the position of the adjusting block changes, the distance for adjustment is used to change the outer diameter size of the rotor body. Then, the first bolt is tightened again to fix the rotor tip movable block at a new position, completing the adjustment process.

[0017] In the present utility model, for the rotor with adjustable rotor tip, through the cooperation of the adjusting component and the limiting component, the outer diameter size of the rotor can be conveniently adjusted, its original performance can be restored, there is no need to replace the entire rotor or equipment, and the maintenance cost is reduced;

[0018] In the present utility model, for the adjustable rotor with rotor tips, both the adjustment assembly and the limit assembly are connected to the rotor body by bolts, which is easy to operate, facilitates quick adjustment, and can ensure the stable operation of the rotor after adjustment.

[0019] In the present utility model, through the cooperation of the adjustment assembly and the limit assembly, the outer diameter size of the rotor can be conveniently adjusted to restore its original performance without replacing the entire rotor or equipment, reducing the maintenance cost. Both the adjustment assembly and the limit assembly are connected to the rotor body by bolts, which is easy to operate, facilitates quick adjustment, and can ensure the stable operation of the rotor after adjustment.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to 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.

[0025] Embodiment 1

[0026] Referring to Figures 1-3 , a rotor includes a rotor body 1 and four groups of adjustment assemblies and four limit assemblies provided thereon. Four grooves 2 are equidistantly opened on the rotor body 1, and a plurality of fixing holes 8 and two groups of limit holes 9 are opened on the bottom inner wall of each groove 2, and each group of limit holes 9 includes at least three hole positions.

[0027] Regarding the specific implementation of the adjustment component, a set of adjustment components is provided in each groove 2. This set of adjustment components includes a rotor tip movable block 3. The rotor tip movable block 3 is slidably connected to the inner walls on both sides of the corresponding groove 2, thereby allowing it to move radially within the groove 2. A plurality of first through holes 5 corresponding to the fixing holes 8 are opened in the rotor tip movable block 3. First bolts 6 are provided in these first through holes 5. The first bolts 6 are tightly fitted with the corresponding fixing holes 8 by means of threaded connection, thereby fixing the rotor tip movable block 3 in the groove 2 of the rotor body 1. When it is necessary to adjust the outer diameter size of the rotor body 1, the first bolts 6 can be loosened, the rotor tip movable block 3 can be slid along the groove 2 to a suitable position, and then the first bolts 6 can be tightened again to complete the adjustment.

[0028] This application can be used in the technical field of rotor pumps and can also be used in other fields applicable to this application.

[0029] Embodiment 2

[0030] Reference Figures 2-3 , on the basis of Embodiment 1, an improvement is made: A rotor tip adjustable rotor is applied to the technical field of rotor pumps. Regarding the specific implementation of the limiting component, a limiting component is provided in each groove 2. This limiting component includes two adjustment blocks 4. These two adjustment blocks 4 are also slidably connected to the inner walls on both sides of the corresponding groove 2, and their tops are in contact with the bottom of the rotor tip movable block 3. Second through holes are opened in the adjustment blocks 4. Second bolts 7 are provided in the second through holes. The second bolts 7 are tightly fitted with the corresponding limiting holes 9 by means of threaded connection, thereby fixing the adjustment blocks 4 at different positions in the groove 2. When the rotor tip movable block 3 is worn due to long-term use, resulting in a reduction in the outer diameter size of the rotor body 1, the second bolts 7 can be loosened, the adjustment blocks 4 can be adjusted to appropriate positions accordingly, and then the second bolts 7 can be tightened again. Since the sides of the rotor tip movable block 3 and the adjustment blocks 4 that are close to each other are both provided as inclined surfaces, when the positions of the adjustment blocks 4 change, the distance between the rotor tip movable block 3 and the inner wall of the bottom of the groove 2 will also change accordingly, so as to achieve the purpose of restoring the original outer diameter size of the rotor body 1.
