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.

What are the different fluid media used in fluid drive couplings, such as oil or water?
Fluid drive couplings can use various types of hydraulic fluids as the medium to transmit torque between the driving and driven elements. The choice of fluid media depends on the specific application requirements and the operating conditions. Some common fluid media used in fluid drive couplings include:
- Oil: Mineral oil, synthetic oil, or a blend of various oils are commonly used as hydraulic fluids in fluid drive couplings. These oils offer good lubrication properties and thermal stability, making them suitable for various industrial applications. Oil-based fluid drive couplings are often preferred for heavy-duty and high-temperature applications.
- Water-Glycol: Water-glycol mixtures are widely used as hydraulic fluids in fluid drive couplings that require fire-resistant properties. These fluids are commonly used in industries where fire hazards are a concern, such as steel mills and foundries.
- Water-Oil Emulsions: Emulsions of water and oil are used in certain fluid drive couplings, especially in applications where fire resistance and cooling properties are essential. Water-oil emulsions provide both good lubrication and effective heat dissipation capabilities.
- Water: In some specific applications, plain water is used as the hydraulic fluid in fluid drive couplings. Water offers excellent cooling properties and is suitable for applications where there is no risk of freezing or where fire resistance is not a primary concern.
- Biodegradable Fluids: Biodegradable hydraulic fluids, such as vegetable-based oils or synthetic esters, are employed in environmentally sensitive applications. These fluids are biodegradable and offer good lubrication properties while minimizing environmental impact.
- Specialty Fluids: Depending on the specific requirements of niche applications, other specialty hydraulic fluids with unique properties may be used in fluid drive couplings. These specialty fluids are tailored to meet specific demands, such as extreme temperatures or aggressive operating environments.
The selection of the appropriate hydraulic fluid for a fluid drive coupling depends on factors like the operating temperature, load conditions, environmental considerations, and compatibility with the coupling’s materials. Manufacturers usually provide guidelines on the suitable fluid types and specifications for their specific fluid drive coupling models.
Regular monitoring and maintenance of the hydraulic fluid are essential to ensure optimal performance and to extend the service life of the fluid drive coupling. Fluid condition monitoring helps identify any signs of contamination or degradation, enabling timely fluid replacement or treatment as necessary.
It is crucial to follow the manufacturer’s recommendations regarding fluid type, fluid level, and fluid change intervals to ensure the fluid drive coupling operates efficiently and reliably in its intended application.

How do you select the right fluid drive coupling for specific machinery or equipment?
Selecting the right fluid drive coupling is crucial to ensure optimal performance, efficiency, and reliability of machinery or equipment in various industrial applications. The selection process involves considering several factors to match the coupling’s characteristics with the specific requirements of the application. Here are the steps to guide you in selecting the appropriate fluid drive coupling:
- Identify Application Requirements: Understand the operational requirements of the machinery or equipment. Determine the torque and speed range, the need for speed regulation, and any specific start-up conditions or load variations.
- Type of Fluid Drive Coupling: Based on the application requirements, choose the appropriate type of fluid drive coupling. Consider constant-fill couplings for consistent speed regulation, variable-fill couplings for adjustable speed control, and delayed-fill couplings for gradual start-ups.
- Power Rating: Determine the power rating required for the machinery or equipment. Ensure the selected fluid drive coupling can handle the expected torque and power levels without exceeding its capacity.
- Speed Range: Check the speed range capability of the fluid drive coupling. It should match the operating speeds of the machinery to provide the desired performance during both low and high-speed operations.
- Slip Control: Evaluate the need for slip control in the application. Some applications may require slip to protect against sudden overloads or to provide controlled acceleration.
- Overload Protection: If overload protection is essential for the machinery or equipment, ensure the selected coupling can handle transient loads without damage.
- Fluid Compatibility: Consider the compatibility of the hydraulic fluid with the application’s operating conditions. The fluid should have suitable viscosity and temperature characteristics for efficient power transmission and to avoid fluid breakdown.
- Environmental Conditions: Evaluate the environmental conditions, such as temperature, humidity, and the presence of contaminants, to ensure the fluid drive coupling can operate reliably under such conditions.
- Space Constraints: Check the available space for coupling installation. Some fluid drive couplings may have specific space requirements that need to be accommodated.
- Budget and Cost: Consider the budget constraints and balance them with the performance requirements. Choose a fluid drive coupling that offers the best value for money without compromising on critical features.
It’s essential to work closely with experienced fluid power engineers, coupling manufacturers, or suppliers during the selection process. They can provide valuable insights and assistance in choosing the most suitable fluid drive coupling for the specific machinery or equipment application.
Additionally, consulting the coupling manufacturer’s technical specifications, performance data, and application guidelines will further aid in making an informed decision. Regular maintenance and monitoring of the fluid drive coupling’s performance are vital to ensure it continues to function optimally and extends the machinery or equipment’s lifespan.
In summary, selecting the right fluid drive coupling involves a comprehensive analysis of the machinery’s requirements, coupling characteristics, and operational conditions. By considering these factors and seeking professional advice, you can make an informed choice that enhances the efficiency and reliability of your machinery or equipment.
