Coupling Performance

1 has a slow shock and torsional vibration isolation performance ; allow the motor to start with a delay time , slow acceleration , reducing sudden start caused by the impact of the interaction between parts .(2) with light loads, the motor starting performance : Due to coupling of the pump wheel torque proportional to the square of its speed , it is the moment when the starter pump wheel torque is minimal due to low speed motor with pump similar bye -load starting , so start time is short, starting Hydraulic pipe fittings  current, starting a smooth , especially for heavy starting high inertia loads .3 with Overload Protection Performance : Since no mechanical coupling is directly connected , when the external load exceeds a certain limit , the pump wheel torque is no longer rising , as usual at this time the motor rotates the output decelerate to a stop , the power drawn from the power supply into heat the coupling temperature until the fusible plug ejection so that the input and the output is cut off , the protection of the motor , the working machine from damage , thereby reducing the failure rate of the machine , maintenance costs and downtime , extending the service life of the motor work load .
