Sealed end face self-compensating radar water slide ring

Abstract

The present invention is a sealed end face self-compensating radar water slide ring which is mainly formed by a static shaft, a rotation shaft, a shell and a mechanical seal. The sealed end face self-compensating radar water slide ring is used for supplying cooling water to a cooling system in a rotation antenna cabin, ensuring the circulation of the cooling water in a cooling water source and the cooling system in the antenna cabin and solving a water slide ring key leakage problem. According to the sealed end face self-compensating radar water slide ring, water inlet and outlet are at the lower end of the static shaft, return water inlet and outlet are at the upper end of the rotation shaft, water inlet and outlet channels are at two sides of the static shaft and the rotation shaft, the space between the water inlet and outlet channels is sealed by a maze, the structural complexity of the water slide ring can be effectively reduced, an self-designed mechanical seal with compact structure is used by the seal among a water inlet channel, a water return channel and the outside, the mechanical seal has an automatic compensation function, and the reliability and life problems of mechanical dynamic seal are solved. The sealed end face self-compensating radar water slide ring can be directly used in a large modern power radar with the need of liquid cooling and has the advantages of compact structure, low cost, large diameter, high reliability, long life and good maintenance.

Description

technical field [0001] The invention belongs to the radar structure technology, and is a hinge that transports the cooling water source of the radar to the cooling system in the rotating antenna cabin to ensure the circulation of the cooling water in the cooling water source and the cooling system in the antenna cabin without leakage. Through the labyrinth seal between the water inlet and outlet channels, mechanical seals are used between the water inlet channel, the water outlet channel and the outside world to solve the reliability and life of the water slip ring. Background technique [0002] In the liquid cooling system of modern phased array radar, a water slip ring is needed between the rotating antenna and the fixed base to ensure the circulation of cooling liquid. The water slip ring is a key part of the entire liquid cooling system of the radar. The water slip ring uses a rotary mechanical seal. The rotary seal still has problems such as complex structure, difficult...

Problems solved by technology

[0004] The present invention is to solve the complex structure of the conventional water slip ring and the leakage problem during the working process. The present invention is mainly composed of a static shaft, a rotating shaft, an inlet and outlet channel, a casing, and a mechanical seal. The static shaft and the rotating shaft are installed on the On the shell, a labyrinth seal is used between the water inlet and outlet, and a mechanical seal is used for the seal between the water inlet and outlet and the outside world. The water inlet and outlet are located at the lower end of the static shaft, and the return water inlet and outlet are located at the upper end of the rotating shaft. both sides
