As shown in fig. 1 to 4, the detailed structure and the work flow of the dynamic balancer nozzle regulator are illustrated.

Specifically, as shown in fig. 1 and 2, the dynamic balancer nozzle adjuster includes a fixed ring 10 and a rotating ring 20 rotatably disposed in or outside the fixed ring 10, the nozzle set includes a plurality of nozzles 5 circumferentially disposed between the fixed ring 10 and the rotating ring 20 at intervals, one end of each nozzle 5 is rotatably disposed in the fixed ring 10, and the other end is linked with the rotating ring 20, wherein when the rotating ring 20 is driven to rotate relative to the fixed ring 10, the rotating ring 20 is linked to drive the nozzle 5 to rotate, so that the nozzle set and the rotating ring 20 rotate in the same direction, thereby adjusting the outlet radius of the nozzle set.

It is understood that the rotating ring 20 may be disposed inside the fixing ring 10, or may be disposed outside the fixing ring 10, which is not limited by the present invention. In this embodiment of the present invention, the rotating ring 20 is disposed inside the stationary ring 10.

Further, the fixed ring 10 is provided with a rotating groove 13, the rotating ring 20 is provided with a nozzle radius limiting groove 23, the dynamic balancing instrument nozzle regulator further comprises a rotating shaft 7 arranged in the rotating groove 13 of the fixed ring 10 and a limiting pin 15 slidably arranged in the nozzle radius limiting groove 23, the rotating shaft 7 is sleeved at one end of the nozzle 5 so that the end of the nozzle 5 can rotate by taking the rotating shaft 7 as a fulcrum, and the limiting pin 15 is connected to the other end of the nozzle 5 so as to form a state that the other end of the nozzle 5 is linked with the rotating ring 20; when the rotating ring 20 is driven to rotate relative to the fixed ring 10, the rotating ring 20 drives the nozzles 5 to rotate around the rotating shaft 7 as a fulcrum through the limiting pin 15 in a linkage manner, so that the nozzle group and the rotating ring 20 rotate in the same direction, and the outlet radius of the nozzle group is adjusted.

Furthermore, as shown in fig. 3, the fixing ring 10 includes an upper fixing ring 12 and a lower fixing ring 11, a plurality of rotating slots 13 are formed between the upper fixing ring 12 and the lower fixing ring 11, each rotating slot 13 has two opposite arc-shaped side walls, the rotating shaft 7 has a spherical side surface, and the spherical side surface of the rotating shaft 7 contacts with the corresponding arc-shaped side wall, so that the nozzle 5 can rotate with the rotating shaft 7 as a fulcrum.

It can be understood that, when the nozzles 5 are linked by the rotating ring 20, the single nozzle 5 performs a swinging motion in the dynamic balancer adjuster with the rotating shaft 7 as a fulcrum, and the swinging range is an angle range defined by the corresponding nozzle angle limiting groove 24. The movement of the entire nozzle group is a rotational movement in accordance with the rotational direction of the rotating ring 20, and if the rotating ring 20 rotates counterclockwise, the entire nozzle group also rotates counterclockwise, and if the rotating ring 20 rotates clockwise, the entire nozzle group also rotates clockwise. The adjustment range of the outlet radius of the nozzle group is then limited by the nozzle radius limiting groove 23.

It can also be understood that, when the outlet of the nozzle 5 is closest to the impeller 30, which is the minimum radius adjustment range of the dynamic balancer nozzle adjuster, when the rotating ring 20 is rotated counterclockwise, the nozzle group is also rotated counterclockwise, and the outlet radius thereof becomes larger, so that the outlet radius of the nozzle group can be adjusted to a proper position according to the size of the impeller 30.

In particular, the nozzle-radius limiting groove 23 defines the range of the outlet radius of the entire nozzle ring, and when the rotating ring 20 is relatively displaced with respect to the fixed ring 10, the rotating ring 20 pushes the limiting pin 15 in the circumferential direction, which results in the radial displacement change of the limiting pin 15, that is, the rotating ring 20, the nozzle-radius limiting groove 23 and the limiting pin 15 are the key for the linkage of all the nozzles 5, and the important point is the pushing action in the circumferential direction, so that a space must be reserved in the radial direction, that is, the nozzle-radius limiting groove 23 is provided.

Specifically, the nozzle angle limiting grooves 24 have a trapezoidal groove structure that the width of the groove increases from narrow to wide in the direction from the fixed ring 10 to the rotating ring 20, and the nozzle radius limiting grooves 23 are respectively located in the corresponding nozzle angle limiting grooves 24.

It can be understood that the rotation range of the nozzles 5 is limited by the nozzle angle limiting groove 24, so that the adjustment precision of the outlet radius of the whole nozzle group can be ensured while avoiding the mutual interference of the nozzles 5.

Further, as shown in fig. 4, the nozzle 5 has a head portion 51, a main body portion 52 connected to the head portion 51, and a nozzle opening 53 connected to the main body portion 52, the head portion 51 is larger than the main body portion 52 and protrudes from the fixing ring 10, the main body portion 52 has two opposite limiting surfaces 521, the limiting pin 15 is inserted into the main body portion 52, two ends of the limiting pin are respectively located in the nozzle radius limiting grooves 23 of the upper rotating ring 22 and the lower rotating ring 21, and the nozzle opening 53 is a sharp nozzle structure that is bent and extends from the main body portion 52 and is tapered.

In particular, the dynamic balancer nozzle regulator further comprises a plurality of nozzle fastening bolts 6, and the nozzle fastening bolts 6 are abutted with the corresponding limiting surfaces 521 of the nozzles 5, so that circumferential rotation of the nozzles 5 is avoided, and the same outlet direction of the nozzles 5 is ensured.

That is, the nozzle fastening bolt 6 is used for interacting with the limiting surface 521 of the nozzle 5, so as to prevent the nozzle 5 from rotating inside the rotating shaft 7, thereby ensuring that the nozzles 5 can keep consistent angles and directions when rotating, ensuring that the outlet directions of the whole nozzle group are consistent, and providing uniform high-pressure air flow for inlets of different impellers 30.

It should be noted that a circular slide rail 14 is disposed between the fixed ring 10 and the rotating ring 20, so that the fixed ring 10 and the rotating ring 20 can slide relatively.

In addition, it is worth mentioning that the upper fixing ring 12 and the lower fixing ring 11 are fixedly connected through a plurality of fixing ring fastening bolts 8, and the upper rotating ring 22 and the lower rotating ring 21 are fixedly connected through a plurality of rotating ring fastening bolts 9.

It is understood that the direction of the air flow of the nozzle 5 is counterclockwise, which is the moving direction of the impeller 30; when the outlet of the nozzle 5 is closest to the impeller 30, the minimum radius adjustment range of the dynamic balancer nozzle adjuster is obtained. When the fixed ring 10 is kept still and the rotating ring 20 rotates relatively counterclockwise, the airflow direction of the nozzle 5 changes to be counterclockwise, and the impeller 30 is driven to start to rotate at high speed; when the rotating ring 20 is rotated relative to the fixed ring 10, the plurality of nozzles 5 can be simultaneously driven to rotate, the directions of the nozzles 5 are kept consistent, and the outlet radius of the whole nozzle group begins to increase, and the nozzles can be adjusted to a proper position according to the outer diameter of the impeller 30.
