Hydrodynamic Coupling with Double Fluid Units

1. Smoother Start-up with Hydraulic coupling with double fluid units: The dual chambers can be filled with oil in stages or in tandem, achieving an extremely smooth, shock-free start-up, particularly suitable for ultra-high inertia loads.

2. Enhanced Heat Dissipation with Hydraulic coupling with double fluid units: The two chambers provide double the heat dissipation surface area, more effectively dissipating heat generated during operation, suitable for long-term heavy loads or frequent start-stop cycles.

3. Higher Power Transmission with Hydraulic coupling with double fluid units: The dual-chamber design significantly improves torque transmission capacity within similar dimensions.

4. Higher Reliability with Hydraulic coupling with double fluid units: If one chamber fails (e.g., seal failure), the other chamber can still provide partial torque transmission and buffering, resulting in better system redundancy.

  • Information

A dual-chamber hydraulic coupling is a unique design that integrates two independent working chambers within a single housing. Its core advantage doesn't stem from a completely new principle, but rather from structural innovation that significantly enhances the "flexible transmission" and "overload protection" capabilities of the hydraulic coupling core components.


Simply put, you can think of it as combining two ordinary coupling into one, working collaboratively to solve key challenges in high-performance, heavy-duty applications.


Product Advantages:


1. The dual fluid unit design of the fluid coupling makes the transmission efficiency as high as over 95%.

2. The fluid coupling with two fluid power units effectively absorbs and reduces the impact force during startup and shutdown, protects the equipment and prolongs the service life.

3. The fluid coupling with two fluid power units has a simple structure, is easy to disassemble and clean, and reduces maintenance costs.

4. The hydro coupling with two fluid power units is suitable for all kinds of industrial equipment.

5. The design of the hydro coupling with two fluid power units meets environmental protection standards and reduces the impact on the environment.

Working Principle:

The fluid coupling with double fluid units transmits the rotational power of the motor to two fluid units through the input shaft. In the fluid unit, the specific working fluid generates centrifugal force through rotation, thereby effectively transmitting power to the output shaft. According to the change of load, the speed and pressure of the fluid flow are automatically adjusted to achieve smooth torque transmission. At the same time, the fluid can take away heat during the circulation process, ensuring that the equipment works in an efficient state.


Application scenarios:

Heavy-duty belt conveyors: Used for main conveyor belts in mines spanning several kilometers, enabling "zero-impact" startup, protecting the conveyor belt and mechanical structure, and withstanding the thermal loads of long-term heavy-duty operation.


Large ball mills and rotary kilns: Used in rotating equipment weighing hundreds of tons, ensuring minimal starting current and handling the enormous heat dissipation requirements of high inertial loads.


Ship propulsion and special heavy machinery: Plays a role in space-constrained applications requiring high power density and extremely high reliability.
