Embodiment 1

[0029] see image 3 , Figure 4 , Figure 5 and Figure 6 , Embodiment 1 of the present invention, an adjustable seal ring for a centrifugal pump set, including a seal ring body 1, the seal ring body 1 is a disconnected ring structure, and a gap 2 is formed at the disconnection of the seal ring body , the width of the gap 2 is d1, the gap 2 is Z-shaped, and the gap 2 is used for the installation and adjustment of the seal ring; the inclination angle of the inner wall surface of the seal ring body 1 is α1, and the inclination angle of the outer wall surface of the seal ring body is α2, the cross-section of the seal ring body 1 is approximately rhombus-shaped. The sealing ring body 1 is installed between the pump body 10 and the impeller 20 .

[0030] The outer wall surface of the seal ring body 1 is in contact with the seal ring installation part of the pump body 10; the rear end of the seal ring body 1 protrudes outside the rear end of the seal ring installation part of th...

Embodiment 2

[0036] see Figure 7 , Embodiment 2 of the present invention is an adjustable sealing ring for a centrifugal pump unit. The main difference from Embodiment 1 is that the notch is linear. In order to prevent the inconvenient cleaning after the particles enter the "Z-shaped" gap, or for the convenience of processing, the "Z-shaped" gap is processed into a straight-line gap.

[0037] To sum up, the adjustable sealing ring for the centrifugal pump unit of the present invention can not only facilitate the installation of the sealing ring, but also facilitate the maintenance of the sealing ring, reduce the difficulty of installation and processing of the pump unit, and reduce the replacement frequency of the sealing ring. Make the installation and maintenance process of the pump set easier and faster.

Abstract

The invention discloses an adjustable sealing ring for a centrifugal pump set. The sealing ring comprises a sealing ring body, the sealing ring body is of a disconnected annular structure, and a notch is formed at the disconnected part of the sealing ring body; the outer side wall face and the inner side wall face of the sealing ring body are each provided with an inclined angle, and the section of the sealing ring body is in an approximate rhombus shape; the outer side wall surface of the sealing ring body is in contact with a sealing ring mounting part of the pump body; a mounting allowance with the length of d3 exists between the front end of the sealing ring body and the front end of the sealing ring mounting part of the pump body; a mounting allowance with the length of d2 exists between the rear end of the sealing ring body and the rear end of the sealing ring mounting part of the pump body; and a mounting gap d4 is formed between the inner side wall surface of the sealing ring body and the impeller. According to the adjustable sealing ring for the centrifugal pump set, the installation and maintenance processes of the sealing ring of the pump set are relatively simple, and the working efficiency of workers and the working efficiency of the pump set are improved.

Description

technical field [0001] The invention relates to an adjustable sealing ring for a centrifugal pump unit. Background technique [0002] In the design of centrifugal pump sets, in order to reduce the wear between the stator and the rotor, it is often necessary to install sealing rings, throttling bushes and other similar components at the contact parts of the stator and the rotor. as follows figure 1 , figure 2 shown. [0003] see figure 1 and figure 2 , sealing ring 1' and similar parts are used in single-stage pumps and multi-stage pumps, usually, the installation of sealing ring 1' and pump body 2' (see figure 1 ), sealing ring 1' and middle section 3' installation (see figure 2 ), the installation of impeller 4' and guide vane sleeve 5' (see figure 2 ) are: interference fit, transition fit, clearance fit. [0004] When the sealing ring is interference fit, it needs to adopt processes such as hot fitting or cold fitting, and the operation is complicated. [0005...
