Abstract

The invention relates to a speed regulating device for a fixed conduit nozzle valve-controlled hydraulic coupler. The speed regulating device comprises an impeller and a turbine, wherein, the side wall of an impeller cover is provided with a nozzle, the outside of the impeller cover is provided with an outer cover, blades are arranged inside the outer cover, the outer cover is provided with oil holes communicated with a working space formed by the impeller and the turbine, and the outer cover is internally provided with a fixed conduit; the opening of the fixed conduit faces high-speed rotating circulation oil enter direction of working oil in the outer cover, the fixed conduit is provided with a check valve, and a pneumatic proportional regulating valve, an electric proportional regulating valve or an electro-pneumatic proportional regulating valve is arranged on an oil circuit at the inlet of the working space. The speed regulating device has the outstanding advantages of being capable of realizing quick 'on / off' functions of the coupler by regulating the proportional regulating valves, and realizing stepless regulation on the filling amount of the working space and the output rotating speed of the coupler.

Description

Technical field: [0001] The invention relates to the technical field of hydraulic couplings, in particular to a fixed conduit nozzle valve-controlled hydraulic coupling speed regulating device. Background technique: [0002] The hydraulic coupling is a non-rigid coupling with liquid as the working medium, also known as the hydraulic coupling. The pump wheel and the turbine of the hydraulic coupling form a closed working chamber that can circulate the liquid. The pump wheel is installed on the input shaft, and the turbine is installed on the output shaft. When the power machine (internal combustion engine, electric motor, etc.) drives the input shaft to rotate, the liquid is thrown out by the centrifugal pump wheel, and the pump wheel converts the mechanical energy of the power machine into the kinetic energy of the working oil. After this high-speed liquid enters the turbine, it drives the turbine to rotate. The turbine converts the kinetic energy of the working oil into me...
