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.

How Do Rigid Couplings Compare to Other Types of Couplings in Terms of Performance?
Rigid couplings offer specific advantages and disadvantages compared to other types of couplings, and their performance depends on the requirements of the application:
1. Performance: Rigid couplings provide excellent torque transmission capabilities and are best suited for applications that demand precise and efficient power transfer. They have minimal backlash and high torsional stiffness, resulting in accurate motion control.
2. Misalignment Tolerance: Rigid couplings cannot tolerate misalignment between shafts. They require precise shaft alignment during installation, which can be time-consuming and may result in increased downtime during maintenance or repairs.
3. Vibration Damping: Rigid couplings offer no damping of vibrations, which means they may not be suitable for systems that require vibration isolation or shock absorption.
4. Maintenance: Rigid couplings are generally low maintenance since they have no moving parts or flexible elements that can wear out over time. Once properly installed, they can provide reliable performance for extended periods.
5. Space Requirements: Rigid couplings are compact and do not add much length to the shaft, making them suitable for applications with limited space.
6. Cost: Rigid couplings are usually more economical compared to some advanced and specialized coupling types. Their simpler design and lower manufacturing costs contribute to their affordability.
7. Application: Rigid couplings are commonly used in applications where shafts are precisely aligned and no misalignment compensation is necessary. They are prevalent in precision machinery, robotics, and applications that require accurate motion control.
In contrast, flexible couplings, such as elastomeric, jaw, or beam couplings, are designed to accommodate misalignment, dampen vibrations, and provide some degree of shock absorption. Their performance is ideal for systems where shafts may experience misalignment due to thermal expansion, shaft deflection, or dynamic loads.
In summary, rigid couplings excel in applications that demand precise alignment and high torque transmission, but they may not be suitable for systems that require misalignment compensation or vibration damping.
Factors to Consider When Choosing a Rigid Coupling for a Specific System
Choosing the right rigid coupling for a specific system is crucial to ensure proper functionality and reliable performance. Several factors should be considered when making this decision:
1. Shaft Size and Compatibility: The most fundamental factor is ensuring that the rigid coupling is compatible with the shaft sizes of the connected components. The coupling should have the appropriate bore size and keyway dimensions to fit securely onto the shafts.
2. Operating Torque: Consider the torque requirements of the application. The rigid coupling should have a torque rating that exceeds the maximum torque expected during operation to prevent failures and ensure safety.
3. Speed: Determine the rotational speed (RPM) of the connected shafts. Rigid couplings have maximum RPM limits, and the selected coupling should be capable of handling the system’s operating speed.
4. Misalignment Tolerance: Assess the potential misalignment between the shafts. Rigid couplings provide no flexibility, so the system must have minimal misalignment to prevent excessive forces on the components.
5. Temperature and Environment: Consider the operating temperature range and the environment where the coupling will be used. Ensure the chosen material can withstand the temperature and any corrosive or harsh conditions present.
6. Space Limitations: Evaluate the available space for the coupling. Rigid couplings have a compact design, but ensure that there is enough clearance for installation and maintenance.
7. Backlash and Torsional Stiffness: In some precision systems, backlash must be minimized to maintain accurate positioning. Additionally, the torsional stiffness of the coupling can impact system response and stability.
8. Keyway or Keyless Design: Decide between a coupling with a keyway or a keyless design based on the specific application requirements and ease of installation.
9. Material Selection: Consider the material properties of the rigid coupling. Common materials include steel, stainless steel, and aluminum, each with its own advantages and limitations.
10. Maintenance: Determine the maintenance requirements of the coupling. Some couplings may need periodic lubrication or inspections, while others may be maintenance-free.
11. Cost: While cost should not be the sole consideration, it is essential to evaluate the cost-effectiveness of the coupling, taking into account its performance and longevity.
By carefully considering these factors, you can select the most suitable rigid coupling for your specific system, ensuring optimal performance, and longevity of your mechanical setup.
Materials Used in Manufacturing Rigid Couplings:
Rigid couplings are designed to provide a strong and durable connection between two shafts, and they are commonly made from a variety of materials to suit different applications. The choice of material depends on factors such as the application’s environment, load capacity, and cost considerations. Some common materials used in manufacturing rigid couplings include:
- 1. Steel: Steel is one of the most widely used materials for rigid couplings. It offers excellent strength, durability, and resistance to wear. Steel couplings are suitable for a wide range of applications, including industrial machinery, automotive systems, and power transmission.
- 2. Stainless Steel: Stainless steel couplings are used in applications where corrosion resistance is crucial. They are well-suited for environments with high humidity, moisture, or exposure to chemicals. Stainless steel couplings are commonly used in food processing, pharmaceuticals, marine, and outdoor applications.
- 3. Aluminum: Aluminum couplings are known for their lightweight and corrosion-resistant properties. They are often used in applications where weight reduction is essential, such as aerospace and automotive industries.
- 4. Brass: Brass couplings offer good corrosion resistance and are commonly used in plumbing and water-related applications.
- 5. Cast Iron: Cast iron couplings provide high strength and durability, making them suitable for heavy-duty industrial applications and machinery.
- 6. Bronze: Bronze couplings are known for their excellent wear resistance and are often used in applications involving heavy loads and low speeds.
- 7. Plastics: Some rigid couplings are made from various plastics, such as nylon or Delrin. Plastic couplings are lightweight, non-conductive, and suitable for applications where electrical insulation is required.
It’s essential to consider the specific requirements of the application, including factors like load capacity, operating environment, and cost, when choosing the appropriate material for a rigid coupling. The right material selection ensures that the coupling can withstand the forces and conditions it will encounter, resulting in a reliable and long-lasting connection between the shafts.
