Liquid rotating transmission device resistant to harsh environments

Abstract

The invention discloses a liquid rotating transmission device resistant to harsh environments, and relates to the technical field of sealing and testing. The device comprises a housing, an inner ring,an upper fixed cover, a lower fixed cover, a glyd ring and second sealing rings. The inner ring is rotatably installed inside the housing, the two ends of the inner ring are fixed through the lower fixed cover and the upper fixed cover respectively, the inner ring and the housing are rotatably connected through the glyd ring, and liquid storage cavities are symmetrically arranged at two ends of the glyd ring; double-sided pressure-bearing is carried out on the side walls of both sides of the glyd ring through the two liquid storage cavities arranged on two sides, so that the balance of pressure on both sides is achieved; compared with traditional single-sided pressure, service life of the glyd ring is effectively increased; at the same time, the second sealing rings are arranged at two ends of the liquid storage cavities to further seal the liquid storage cavities, and a design concept of secondary sealing and a special surface wear-resistant coating are adopted, so that "zero leakage" requirement during the service life of the liquid rotating transmission device is met.

Description

technical field [0001] The invention relates to the technical field of sealing and detection, in particular to a liquid rotary transmission device resistant to harsh environments. Background technique [0002] As the key connection equipment for the static and dynamic channels of the cooling system, the liquid rotary transmission device is the only channel connecting the fixed cooling pipeline and the rotating cooling pipeline, and its function is to transfer the cooling liquid in the fixed liquid cooling source to the rotating parts For cooling, it is widely used in nuclear power, petrochemical, radar and shipbuilding and other fields. Many products in these fields have severe vibration shocks, harsh temperature and environmental conditions, strict requirements on weight, and large changes in working posture. General mechanical seals are under these harsh environmental conditions. Leakage will occur, and due to the large change in posture, it is difficult for the liquid rot...

General mechanical seals are under these harsh environmental conditions. Leakage will occur, and due to the large change in posture, it is difficult for the liquid rotary transmission device to realize leakage recovery
