Labyrinth seal structure based on high-speed centrifugal machine and mounting method

Abstract

The invention provides a labyrinth seal structure based on a high-speed centrifugal machine and an installation method, and relates to the technical field of high-speed centrifugal machine sealing. A sealing assembly is mounted on the right side of the main body, and a cleaning assembly is mounted in the sealing assembly; the driving mechanism is mounted in the sealing assembly, and a detection mechanism is mounted on the right side of the main body; when the limiting block is inserted and connected into the guide groove and rotates clockwise by 30 degrees, the two limiting grooves and the two limiting heads are concentrically arranged; it is guaranteed that the labyrinth seal is installed in place, the sealing face cannot be dislocated, installation is more convenient, meanwhile, after installation, the sealing effect is high, the positioning accuracy is high, workers can conveniently and regularly clean liquid in the labyrinth seal, the sealing performance is improved, the risk that a high-speed shaft is damaged is reduced, and high-speed shaft detection is more accurate; the problems that a sealing face is prone to stress deformation, and workers cannot conveniently clean accumulated liquid in the labyrinth seal at regular intervals are solved.

Description

Technical field [0001] The present invention relates to the field of high-speed centrifuge sealing technology, in particular to the labyrinth sealing structure and installation method based on high-speed centrifuge. Background [0002] High-speed centrifuges are conventional laboratory centrifuges, widely used in biology, chemistry, medicine and other scientific research and education and production departments; in order to improve the sealing effect, labyrinth seals are installed on high-speed centrifuges. [0003] However, as far as the current labyrinth seal is concerned, the two sealing surfaces are installed in a horizontal plane with the same position as the gearbox, positioned by a simple positioning pin, but this way in the process of installation, it is easy to deform the sealing surface by force, so that the maze is misaligned and the high-speed shaft produces friction, resulting in the failure of the high-speed shaft and the maze damage, and even leads to major mechan...

Problems solved by technology

[0003] However, as far as the current labyrinth seal is concerned, the two sealing surfaces are installed on a horizontal plane at the same position as the gearbox, and are positioned by simple positioning pins. However, this way is easy to deform the sealing surfaces under force during installation. The misalignment of the labyrinth and the friction of the high-speed shaft will lead to the failure of the high-speed shaft and the labyrinth, and even cause major mechanical accidents, affecting production safety, and it is not convenient for the staff to regularly clean the fluid inside the labyrinth seal, which reduces the sealing performance, and the high-speed shaft is easily damaged. are destroyed, reducing the vibration detection accuracy of high-speed shafts
