Problems solved by technology

[0004] The purpose of the present invention is to provide a method for controlling the sealing gap of a non-contact mechanical seal, which aims to solve the problem that the sealing gap of the grate seal in the prior art cannot be adjusted during the equipment operation stage, and can only be reserved sufficiently large during the installation and commissioning stage. Due to the inevitable collision and wear of the equipment during the working process, the existing sealing equipment will expand the sealing gap after a short period of collision and wear, which will affect the technical problems of the continuation of production.

Abstract

The invention discloses a sealing gap control method for a non-contact mechanical seal. A driving system drives a plurality of expansion pieces to expand and contract, the expansion lengths are adjusted according to the gap measurement condition, and therefore a sealing inner hole and a movable ring are concentric, and airflow excitation caused by eccentricity is restrained; and through up-down adjustment of a control ring, a gap between the movable ring and a static ring is adjustable, and therefore equipment can adjust the sealing gap in the running stage, debugging after dismounting is notneeded, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical seals, in particular to a method for controlling the sealing gap of a non-contact mechanical seal. Background technique [0002] At present, sealing technology plays a very important role in modern industrial production and scientific and technological development. Whether it is to improve the development of science and technology and the level of industrial production technology, or in terms of technological transformation and equipment transformation and renewal, sealing technology occupies an important position and plays an important role. [0003] The sealing gap of the mechanical seal changes with the change of the equipment status. Since the conventional sealing technology is mainly based on the grate tooth seal, the sealing gap of the grate tooth seal cannot be adjusted during the operation of the equipment, and can only be reserved during the installation and commissioning stage. With a sufficie...
