Product Introduction:
Main purpose
The YNRQD series liquid viscous soft starting device utilizes the viscosity of the liquid, i.e. the shear force of the oil film, to transmit torque, speed regulation, parking, and other working conditions. It can be widely used in the soft starting, speed regulation, and soft braking processes of belt conveyors, lifting and transportation machinery, engineering machinery, military machinery, fans, water pumps, and other mechanical products. It can greatly improve and improve the starting, operating, and stopping performance of mechanical equipment, effectively eliminate the impact on electrical and mechanical equipment, achieve automatic overload protection of host equipment, power balance, and other functions, improve the working efficiency and reliability of machinery, save energy, and reduce equipment usage costs.
