Embodiment 1

[0080] An aqueous medium coupling, the sequence of the aqueous medium coupling includes: an input coupling assembly connected to a motor at the input end, a rotating casing for transmission, a turbine and a pump wheel arranged in the rotating casing for transmission, forming The annular closed auxiliary chamber between the rotating casing and the input coupling assembly, the hollow turbine shaft that penetrates the input end and the output end, uses water in the coupling cavity, that is, the space formed by the pump wheel and the rotating casing medium. The input coupling part 12 is composed of an input coupling and related elastic connectors.

[0081] The turbine shaft 1 is hollow, and the hollow portion of the connection end with the input coupling assembly is equipped with an internal pressure relief valve 19, and the auxiliary chamber 11 is a ring formed between the rotating shell 5 and the input coupling assembly 12. The pump wheel 9 is provided with a through hole communic...

Abstract

The invention provides an aqueous medium coupling and an internal pressure release method thereof. The aqueous medium coupling comprises an input coupling assembly arranged at the input end and connected with a motor. A rotary shell is connected with a pump wheel so that a turbine can be arranged in the rotary shell to form an annular sealed chamber between the rotary shell and the pump wheel. The coupling also comprises a hollow turbine shaft, and aqueous media are used in a coupling cavity which is a space formed by the pump wheel and the inside of the rotary shell. The coupling is characterized in that the turbine shaft is hollow, an internal pressure release valve is arranged in the hollow portion of the turbine shaft, when the coupling is overloaded and heated, water is heated and vaporized, and when pressure rises and exceeds a preset value, the internal pressure release valve automatically releases gas or steam to prevent the gas pressure from further rising. The aqueous medium coupling and the internal pressure release method are particularly suitable for scraper conveyers, belt conveyers, reverse loaders, coal ploughs, crushing machines and the like with high flame-proof and anti-explosion requirements for couplings in mine enterprises and the like.

Description

Technical field [0001] The present invention relates to the field of hydraulic transmission and automation. In particular, the present invention relates to an aqueous medium coupling and an internal pressure release method thereof. The aqueous medium coupling and internal pressure release method are particularly suitable for couplings of enterprises such as coal mines. Scraper conveyors, belt conveyors, transfer machines, coal ploughs, crushers, etc. with higher requirements for flame-proof and explosion-proof. Background technique [0002] In mining enterprises such as coal mines, a large amount of scraper conveyor equipment is required. The scraper conveyor and other equipment not only transport coal and materials, but are also used for the running track of the shearer. Therefore, the scraper conveyor has become an indispensable main equipment in the modern coal mining process. Due to the frequent start-ups of the scraper conveyor, large start-ups, large workload changes, seri...
