System Analysis Of Speed-regulating Hydraulic Coupling

Speed-adjustable hydraulic couplings are mainly used in metallurgy, electric power, chemical industry, building materials, coal, port industry, water pumps, blowers, ball mills, crushers and other mechanical equipment. They have improved motor starting performance, prevent motor overload, isolate torsional vibration, speed regulation, energy saving and load balancing which improve the performance advantages of power machines and working machines.

The variable speed hydraulic coupling cavity is filled with a certain amount of working fluid. The mechanical energy of the pump wheel is obtained from the motor and converted into liquid energy. It drives the turbine to convert the liquid energy into mechanical energy, driving the working machine to work and realizing the original operation. Energy transfer from motivation to work machine.

The speed control of a variable speed hydraulic coupling adjusts the rotational kinetic energy by controlling the amount of liquid, thereby changing the output speed of the liquid coupling. The speed of the prime mover is constant, achieving stepless speed regulation.

Changes in the energy transmitted by the variable speed fluid coupling will produce a slip rate, which will heat the working fluid. For the variable speed fluid coupling to work properly, a cooling system must be equipped to cool the liquid.

The electric actuator controls the position of the scoop in the adjusting speed fluid coupling. The electric actuator receives electrical signals to control the position of the scoop in the variable speed hydrodynamic coupling, thereby adjusting the output speed of the output shaft of the variable-speed fluid coupling.

The speed-adjustable hydraulic coupling is suitable for Siemens S7-300PLC and PID control systems. The electric control system of the speed-adjustable fluid coupling controls the position of the scoop to control the speed of the output shaft and feeds back the conduit position signal.
