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.

Is It Possible to Replace a Shaft Coupling Without Professional Assistance?

Yes, it is possible to replace a shaft coupling without professional assistance, especially if you have some mechanical knowledge and the necessary tools. However, the ease of replacement can vary depending on the type of coupling and the complexity of the equipment. Here are some general steps to guide you through the process:

1. Safety First:

Before starting any work, ensure that the equipment is turned off and disconnected from the power source. Use appropriate personal protective equipment (PPE) to protect yourself from potential hazards.

2. Assess the Coupling Type:

Different types of couplings may have specific installation and removal methods. Identify the type of coupling you need to replace, and consult the manufacturer’s documentation or online resources for guidance.

3. Gather Tools and Materials:

Collect the necessary tools, such as wrenches, sockets, and a puller (if required), to safely remove the old coupling. Have the new coupling ready for installation, ensuring it matches the specifications of the old one.

4. Disassembly:

If your coupling is a split or clamp-style coupling, you may be able to replace it without fully disassembling the connected equipment. Otherwise, you may need to remove other components to access the coupling.

5. Remove Fasteners:

Loosen and remove any fasteners, such as set screws, that secure the old coupling to the shafts. Take care not to damage the shafts during this process.

6. Extraction:

If the old coupling is tightly fitted on the shafts, you may need to use a coupling puller or other appropriate extraction tools to safely remove it.

7. Clean and Inspect:

After removing the old coupling, clean the shaft ends and inspect them for any signs of damage or wear. Also, check for any misalignment issues that may have contributed to the old coupling’s failure.

8. Install New Coupling:

Follow the manufacturer’s instructions for installing the new coupling. Apply appropriate lubrication and ensure the coupling is correctly aligned with the shafts.

9. Fasten Securely:

Tighten the fasteners to the manufacturer’s recommended torque values to securely attach the new coupling to the shafts.

10. Test Run:

After installation, perform a test run of the equipment to ensure the new coupling operates smoothly and without issues.

While it is possible to replace a shaft coupling without professional assistance, keep in mind that some couplings and equipment may require specialized knowledge and tools for safe and proper replacement. If you are uncertain about the process or encounter any difficulties, it is advisable to seek help from a qualified professional or technician to avoid potential damage to the equipment or injury to yourself.

Do Shaft Couplings Require Regular Maintenance, and if so, What Does it Involve?

Yes, shaft couplings do require regular maintenance to ensure their optimal performance, extend their service life, and prevent unexpected failures. The maintenance frequency may vary based on factors such as the coupling type, application, operating conditions, and the manufacturer’s recommendations. Here’s what regular maintenance for shaft couplings typically involves:

1. Visual Inspection:

Regularly inspect the coupling for signs of wear, damage, or misalignment. Check for cracks, corrosion, and worn-out elastomeric elements (if applicable). Look for any abnormal movement or rubbing between the coupling components during operation.

2. Lubrication:

If the shaft coupling requires lubrication, follow the manufacturer’s guidelines for the appropriate lubricant type and frequency. Lubrication helps reduce friction, wear, and noise in the coupling.

3. Alignment Check:

Monitor shaft alignment periodically. Misalignment can lead to premature coupling failure and damage to connected equipment. Make adjustments as needed to keep the shafts properly aligned.

4. Torque Check:

For bolted couplings, periodically check the torque on the bolts to ensure they remain securely fastened. Loose bolts can lead to misalignment and reduce coupling performance.

5. Replace Worn Components:

If any coupling components show signs of wear or damage beyond acceptable limits, replace them promptly with genuine replacement parts from the manufacturer.

6. Environmental Considerations:

In harsh environments with exposure to chemicals, moisture, or extreme temperatures, take additional measures to protect the coupling, such as applying corrosion-resistant coatings or using special materials.

7. Monitoring Coupling Performance:

Implement a monitoring system to track coupling performance and detect any changes or abnormalities early on. This could include temperature monitoring, vibration analysis, or other condition monitoring techniques.

8. Professional Inspection:

Periodically have the coupling and connected machinery inspected by qualified professionals to identify any potential issues that may not be apparent during regular inspections.

By adhering to a regular maintenance schedule and taking proactive measures to address potential issues, you can ensure that your shaft couplings operate reliably and efficiently throughout their service life, minimizing downtime and improving overall system performance.

How Does a Flexible Shaft Coupling Differ from a Rigid Shaft Coupling?

Flexible shaft couplings and rigid shaft couplings are two distinct types of couplings, each designed to serve different purposes in mechanical power transmission. Here are the key differences between the two:

1. Flexibility:

The most significant difference between flexible and rigid shaft couplings is their flexibility. Flexible couplings are designed with elements that can deform or flex to accommodate misalignments between the shafts. This flexibility allows for angular, parallel, and axial misalignments, making them suitable for applications where shafts are not perfectly aligned. In contrast, rigid couplings do not have this flexibility and require precise alignment between the shafts.

2. Misalignment Compensation:

Flexible couplings excel in compensating for misalignments, making them ideal for applications with dynamic conditions or those prone to misalignment due to thermal expansion or vibrations. Rigid couplings, on the other hand, are used in applications where perfect alignment is critical to prevent vibration, wear, and premature failure.

3. Damping Properties:

Flexible couplings, particularly those with elastomeric or flexible elements, offer damping properties, meaning they can absorb and reduce shocks and vibrations. This damping capability helps protect the connected equipment from damage and enhances system reliability. Rigid couplings lack this damping ability and can transmit shocks and vibrations directly between shafts.

4. Torque Transmission:

Both flexible and rigid couplings are capable of transmitting torque from the driving shaft to the driven shaft. However, the torque transmission of flexible couplings can be limited compared to rigid couplings, especially in high-torque applications.

5. Types of Applications:

Flexible couplings find applications in a wide range of industries, especially in situations where misalignment compensation, vibration damping, and shock absorption are essential. They are commonly used in conveyors, pumps, compressors, printing presses, and automation systems. Rigid couplings are used in precision machinery and applications that demand perfect alignment, such as high-speed spindles and certain types of precision equipment.

6. Installation:

Flexible couplings are relatively easier to install due to their ability to accommodate misalignment. On the other hand, rigid couplings require careful alignment during installation to ensure proper functioning and prevent premature wear.

The choice between a flexible and a rigid shaft coupling depends on the specific requirements of the application. If misalignment compensation, damping, and flexibility are critical, a flexible coupling is the preferred choice. If precision alignment and direct torque transmission are essential, a rigid coupling is more suitable.
