Governor hydraulic coupling governor hydraulic coupling liquid oil as a medium to transmit the power to coordinate the work of the mechanical coupling speed fluid couplings and other mechanical coupling device compared with the following characteristics: 1 . Variable speed hydraulic coupling in the prime mover speed can change the case of continuous stepless adjustment is driven mechanical speed, when the centrifugal fan, water pump to match its speed range from 1 to 1/4, when the piston When mechanical match its speed range from 1 to 1/3; 2. Governor hydraulic coupling allows the motor idling start, do not select the margin over the prime mover of the motor power capacity, etc., and can reduce the volatility of the grid load; 3. Governor hydraulic coupling with overload protection performance; 4. Isolate vibration, shock mitigation; 5. Variable speed fluid coupling between the transmission components no direct mechanical contact, long life; 6. Governor hydraulic coupling at nominal load has a higher transmission efficiency; 7. Governor hydraulic coupling with a hydraulic control unit and two speed axle, easy to implement remote automatic operation; governor hydraulic coupling with a reasonable structure, advanced performance, high reliability, to meet the metallurgy, building materials and power generation industries require long-term continuous operation conditions. Multi-machine-driven axle load distribution and a constant speed electric motor coupled to the output of the transfer can be adjusted to achieve the output speed of the motor speed under the same circumstances infinitely adjustable within a certain range, can improve motor starting capability, reduce shock and vibration, coordination of multi-machine-driven load distribution, easy to implement remote control and automatic control and can save a lot of energy.
