Hydraulic coupler in carding machine application

Wool Technology hydraulic coupler in carding machine application  carding machine introduced in the coupling unit localization of Shanghai Jiaotong University, Department of Power Mechanical Liuyun Jia, Wang Zhimin (a) of the fluid coupling working principle and characteristics of fluid coupling is the use of liquid (mineral oil) kinetic energy to pass a driving force-type Hydraulic hose fittings  power transmission equipment. There are roughly variable speed couplings and security type (constant filling) coupling of the points. The former is mainly used for speed control, which is used for conveyor belts and starting high inertia loads and has a load to start and overload capability. Safety couplings (hereinafter referred to as coupling) generally consists of the pump wheel, turbine and rotating housing and other major components. The pump wheel and the turbine are arranged symmetrically, a round radiation and many radial blades parallel to the axis. Before running coupling is filled with working oil when the input shaft rotates to drive the pump wheel, due to centrifugal force, the working oil in the pump driven by the rotor blades from the inside to the outer edge of the impeller, a high-pressure high oil flow and toward the turbine blades, the turbine wheel in the same direction following the rotation of the pump. The turbine working oil flows from the inside of the outer edge, and pressure reducer, and then into the inside of the pump wheel. This endless loop. In this cycle the pump wheel is converted to mechanical work input kinetic energy of the working oil pressure and elevated potential, and the working oil turbine will convert kinetic and potential energy into mechanical work output
