Double-cavity hydraulically coupled anti-flying device

Abstract

The invention discloses a double-cavity hydraulically coupled anti-flying device, which comprises a working machine, a box body consisting of a box seat and a box cover, a rotating component supported by the box body and a liquid supply system, wherein the rotating component comprises an input component which is connected with the working machine in a transmission manner, and comprises two pump wheels, and an output component which is fixed on the box body, and comprises two worm wheels; the input component comprises an input shaft, a pump wheel A, a pump wheel B, a pump wheel connection drum and a shell connection drum; the output component comprises a worm wheel A, a worm wheel B and an output shaft; two uniform working cavities are formed by connecting the pump wheel A and the worm wheel A as well as the pump wheel B and the worm wheel B; and the liquid supply system is fixedly connected to the box body. By the double-cavity hydraulically coupled anti-flying device, the rotating speed of the working machine can be reduced, so that an effect of anti-flying is achieved; the double-cavity hydraulically coupled anti-flying device is particularly suitable for anti-flying devices, of which the working machines have the input rotating speed of between 500 and 3,000 r / min and the power range of between 150 and 20,000 KW, or other sets of equipment which requires high speed braking.

Description

Technical field: [0001] The invention relates to the field of hydraulic components, in particular to an anti-flyaway device used for small and medium hydroelectric generator sets or other equipment with large inertia and need to limit the rotational speed. Background technique: [0002] At present, with the advancement of science and technology and the need to adapt to economic development, the working water pressure and energy of small and medium-sized hydroelectric generating units are getting higher and higher, and the safety protection requirements for working equipment are getting higher and higher. If small and medium-sized hydroelectric generating units Or if the speed of the large inertia equipment exceeds the allowable speed value, it will definitely cause an accident. Invention content: [0003] The purpose of the present invention is to provide a double-cavity hydraulic coupling anti-flyaway device, which uses liquid as the working medium, and the hydraulic elem...
