The Guangxing YOTC Variable Speed Fluid Couplings are sophisticated electro-hydraulic solutions engineered to deliver precise stepless speed regulation, soft start capability, and reliable overload protection for a wide range of heavy-duty industrial applications. Utilizing the dynamic interaction of hydraulic fluid within a closed working chamber, YOTC couplings seamlessly transfer energy from the prime mover to the driven machinery while enabling real-time speed adjustments based on operational requirements.
The heart of the YOTC system consists of five main components: rotating parts (pump wheel, turbine, casing, input/output shafts), an integrated oil intake and discharge system, an oil tank, a cooling unit, and an intelligent control system. By adjusting the oil discharge mechanism, the fluid fill rate within the chamber can be varied, allowing continuous, stepless speed modulation of the connected equipment. With efficiency levels as high as 97%, YOTC couplings minimize energy loss even during active speed changes.
The built-in cooling system ensures optimal working fluid temperature, preventing overheating during prolonged operation. YOTC couplings are compatible with modern control technologies, enabling manual, automated, and remote operation using actuators, servo amplifiers, speed sensors, and more.
