Application Case

Typical case of diaphragm coupling applied to variable frequency speed control equipment

JMB type coupling is applied to HangZhou Oilfield Thermal Power Plant

According to the requirements of HangZhou Electric Power Corporation, HangZhou Oilfield Thermal Power Plant should dynamically adjust the power generation according to the load of the power grid and market demand, and carry out the transformation of the frequency converter and the suction fan. The motor was originally a 1600KW, 730RPM non-frequency variable speed motor matched by HangZhou Motor Factory. The speed control mode after changing the frequency is manual control. Press the button speed to increase 10RPM or drop 10RPM. The coupling is still the original elastic decoupling coupling, and the elastic de-coupling coupling after frequency conversion is frequently damaged, which directly affects the normal power generation.

It is found through analysis that in the process of frequency conversion speed regulation, the pin of the coupling can not bear the inertia of the speed regulation process (the diameter of the fan impeller is 3.3 meters) and is cut off, which has great damage to the motor and the fan.

Later, they switched to the JMB460 double-diaphragm wheel-type coupling of our factory (patent number: ZL.99246247.9). After 1 hour of destructive experiment and more than 1 year of operation test, the equipment is running very well, and there is no Replace the diaphragm. 12 units have been rebuilt and the operation is in good condition.

Advancements and Innovations in Fluid Coupling Technology

Fluid coupling technology has undergone significant advancements and innovations over the years, leading to improved performance, efficiency, and versatility. Some notable advancements include:

  • Variable Fill Fluid Couplings: These modern fluid couplings feature a variable fill design that allows for better control of the power transmission. By adjusting the fill level of the coupling, it becomes possible to optimize torque transmission and efficiency across a wider range of operating conditions.
  • Electronic Control: The integration of electronic control systems has brought a new level of intelligence to fluid couplings. Electronic control allows for precise monitoring and adjustment of the coupling’s operation, enabling smoother start-ups, better load sharing, and protection against excessive loads.
  • Smart Coupling Technologies: Some fluid coupling manufacturers offer smart coupling technologies that incorporate sensors and data analytics. These smart couplings can monitor performance parameters in real-time, detect anomalies, and provide valuable insights into the overall system health.
  • High-Temperature Applications: Advancements in material science have led to the development of fluid couplings capable of operating at higher temperatures. This makes them suitable for use in demanding applications, such as heavy industries and high-temperature environments.
  • Efficiency Improvements: Manufacturers have focused on enhancing the overall efficiency of fluid couplings. By reducing internal losses and improving fluid circulation, modern fluid couplings offer higher efficiency, which translates into energy savings and reduced operating costs.
  • Integration with Variable Frequency Drives (VFDs): Fluid couplings can now be integrated with VFDs, combining the benefits of both technologies. The VFD allows for variable speed control, while the fluid coupling provides soft start and overload protection, creating a versatile and efficient power transmission system.

These advancements in fluid coupling technology have made them even more reliable, adaptable, and suitable for various industrial applications. As technology continues to evolve, fluid couplings are likely to see further improvements, making them an integral part of modern power transmission systems.

Fluid Couplings in Hydraulic Drive Systems

Yes, fluid couplings can be used in hydraulic drive systems to transmit power and control the speed of driven components. In hydraulic drive systems, fluid couplings act as a torque converter, providing a smooth and gradual transfer of power between the input and output shafts.

The basic principle of a fluid coupling remains the same whether it is used in a mechanical drive system or a hydraulic drive system. The fluid coupling consists of an input impeller connected to the prime mover (such as an electric motor or an engine) and an output runner connected to the driven component.

When the prime mover is activated, it drives the input impeller, creating a flow of hydraulic fluid within the coupling. This fluid flow creates a hydrodynamic torque that is transferred to the output runner, driving the connected component. The fluid coupling allows for a controlled slip between the input and output, allowing the driven component to start smoothly and gradually reach its desired speed.

In hydraulic drive systems, fluid couplings offer several advantages:

  • Smooth Torque Transmission: Fluid couplings provide smooth torque transmission, reducing shocks and vibrations in the system.
  • Overload Protection: Fluid couplings can protect the drive system from overloads by allowing some slip in the event of sudden changes in load or jamming of the driven component.
  • Speed Control: By controlling the flow of hydraulic fluid, the speed of the driven component can be precisely regulated.
  • Energy Efficiency: Fluid couplings can help improve energy efficiency by reducing mechanical losses and optimizing power transmission.

Hydraulic drive systems with fluid couplings are commonly used in various industrial applications, including conveyor systems, mining equipment, marine propulsion, and more. They offer reliable and efficient power transmission while protecting the machinery from excessive loads and shocks.

It’s essential to consider the specific requirements of the hydraulic drive system and the characteristics of the fluid coupling to ensure optimal performance and efficiency in the application.

Safety Considerations when Working with Fluid Couplings

Fluid couplings are essential components in various industrial applications, and it’s essential to follow safety guidelines when working with them. Here are some safety considerations:

  1. Lockout-Tagout (LOTO): Before performing any maintenance or repair work on a fluid coupling, ensure that the equipment is properly shut down and that the energy sources are locked out and tagged out. This prevents accidental startup and protects personnel from potential hazards.
  2. Fluid Containment: When draining or replacing the fluid in a fluid coupling, use appropriate containers to collect and contain the fluid. Avoid spills, as some coupling fluids may be hazardous.
  3. High Temperatures: Fluid couplings can reach high temperatures during operation. Allow sufficient cooling time before handling or inspecting the coupling to avoid burns or injuries.
  4. Personal Protective Equipment (PPE): Wear appropriate PPE, such as gloves and eye protection, when working with fluid couplings to protect against potential splashes or contact with hot surfaces.
  5. Manufacturer Recommendations: Follow the safety guidelines and instructions provided by the fluid coupling manufacturer for installation, maintenance, and troubleshooting.
  6. Proper Tools: Use the correct tools and equipment for maintenance and assembly tasks to prevent damage to the fluid coupling and ensure safe working conditions.
  7. Training: Ensure that personnel working with fluid couplings are adequately trained in their proper use, maintenance, and safety procedures.
  8. Inspections: Regularly inspect the fluid coupling for any signs of wear, leaks, or abnormalities that could pose safety risks. Address any issues promptly.
  9. Hot Work: Avoid performing hot work (e.g., welding, cutting) in the vicinity of fluid couplings, as the high-temperature fluids and components may present a fire hazard.
  10. Consult Experts: If in doubt or facing complex issues with fluid couplings, consult qualified experts or the manufacturer for guidance.

Adhering to these safety considerations will help minimize risks and ensure a safe working environment when dealing with fluid couplings.
