1. It considerably improves the transmission efficiency and starting of electric machines. It can gently start up equipments of large inertia to save energy, protect environment and prevent waste of power.
2. It protects electric machines and equipments from overloading. In case of stall due to excessive loading, working fluid will be gushed out of the fusible plug to separate the working machine from the loading, protecting electric machines and equipments from damage at starting or overloading. It also mitigates the speed difference caused by impact in operation.
3. It smoothly starts up loading equipments, effectively warding off shock and torsional vibration during the staring up and operation of the equipment.
4. It coordinates the even distribution of loading when several machines operate together. In addition, fluid couplings are relatively simply in structure, easy to use and convenient to maintain.
