Hydrodynamic Coupling
Industrial Fluid Coupling Solutions · Energy Saving · Overload Protection
Hydrodynamic Coupling (Fluid Coupling) is a non-contact power transmission device using kinetic energy of liquid. It is widely used in heavy machinery, mining equipment, conveyor systems, and agricultural machinery. Its core advantages include non-contact torque transmission, shock absorption, and extended equipment life, making it an essential energy-saving component in modern industrial drive systems. We offer everything from standard selection to deep customization, ensuring stable and efficient performance even in harsh working conditions.、

⚙️ Working Principle
The hydrodynamic coupling mainly consists of three parts: pump wheel, turbine, and housing. Power input drives the pump wheel to rotate, which propels the fluid into high-speed flow. The kinetic energy of the fluid is transferred to the turbine, achieving non-contact power transmission:
Normal operation: a flexible fluid connection is formed between the pump wheel and turbine, eliminating mechanical friction and wear from the start.
Overload protection: when load exceeds the set value, fluid pressure automatically adjusts, turbine speed decreases, effectively isolating the motor from the driven machine to prevent motor burnout or equipment damage.
