What Are The Advantages of Variable Speed Hydraulic Coupling

Variable speed fluid coupling uses liquid oil as a medium to transmit power to working machinery; it can coordinate the load distribution of multi-machine drives and with the constant transmission of the shaft speed output by the motor connection; it can be adjusted within a certain range and realizes stepless adjustment of output speed while the motor speed remains unchanged; it can improve the starting ability of the motor; reduce shock and vibration; coordinate the load distribution of multi-machine drives; it is easy to realize remote control and automatic control and can save electric energy.

Compared with other types of couplings, the speed-adjustable hydraulic coupling has the following characteristics: the speed-adjustable hydraulic coupling can continuously and steplessly adjust the speed of the driven machine while the speed of the prime mover remains unchanged. When used with a centrifugal fan or when matched with a water pump, its speed adjustment range is 1 to 1/4, and when matched with a piston machine, its speed adjustment range is 1 to 1/3; the speed-adjustable hydraulic coupling can start the motor without load, without select motors and other prime movers with excessive power margin capabilities, and can reduce fluctuations in grid load; speed-adjustable hydraulic couplings have overload protection capabilities; isolate vibrations and slow down impacts; transmission components of speed-adjustable hydraulic couplings; there is no direct mechanical contact between the couplings and the service life is long; the speed-regulating hydraulic coupling has high transmission efficiency under rated load; the speed-regulating hydraulic coupling has a hydraulic control speed regulating device and two half-shafts, which is easy to achieve long-distance automatic operation; the speed-adjustable hydraulic coupling has a reasonable structure, superior performance, and high reliability, and can meet the long-term continuous operation requirements of metallurgy, building materials, power generation and other industries. It has the performance of starting the motor at light load: since the torque of the coupling's pump wheel is proportional to the square of its speed, at the moment of starting, the torque of the pump wheel is very low due to the low speed, and the motor is similar to starting with a pump wheel without load, so the starting time is short , small starting current, stable starting, especially suitable for starting heavy loads with large inertia.
