Product Detail

Description:

The rigid clamping shaft coupling has the properties of shock mitigation and torsional vibration isolation. Can make the motor starter has a delay time, slow speed, reduce the sudden start caused by the mutual impact between parts, and can make the light load motor starting performance: due to the coupling of the pump is proportional to the square of the wheel torque and rotational speed, therefore, when starting instantaneous pump wheel due to the low speed torque, motor similar to bye with pump load starting, so short starting time, small starting current, Smooth starting, especially suitable for starting heavy load with large inertia.
