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.

Can Tyre Couplings Absorb Shock and Vibration in Rotating Equipment?

Yes, tyre couplings are designed to absorb shock and vibration in rotating equipment, making them well-suited for a wide range of industrial applications. The unique construction of tyre couplings allows them to effectively dampen vibrations and mitigate the impact of shock loads, providing several benefits to the connected machinery and equipment:

• Vibration Damping: The rubber tyre element in the coupling acts as a flexible medium that can deform slightly under dynamic loads. When the equipment experiences vibrations during operation, the rubber element absorbs and dampens these vibrations, preventing them from propagating through the connected shafts. This helps reduce vibration levels and minimizes the transmission of vibrations to other parts of the machinery.
• Mitigating Shock Loads: In many industrial applications, rotating equipment can experience sudden shock loads due to factors such as sudden starts, stops, or impacts with external objects. Tyre couplings are designed to handle such shock loads by providing a cushioning effect. The rubber tyre element can compress and absorb the energy generated by the shock, protecting the connected equipment from damage and preventing sudden stress on the shafts and bearings.
• Accommodating Misalignments: In addition to vibration damping and shock absorption, tyre couplings can also accommodate misalignments between the connected shafts. Misalignments may occur due to manufacturing tolerances, thermal expansion, or other factors. The flexibility of the rubber tyre element allows for a degree of angular, parallel, and axial misalignment, preventing excessive forces and wear on the machinery components.
• Extended Equipment Lifespan: By effectively absorbing vibrations and shock loads, tyre couplings contribute to the longevity of rotating equipment. Reduced vibration levels and lower stress on the components result in less wear and tear, leading to longer service life for bearings, seals, gears, and other critical parts.
• Smooth and Reliable Operation: Tyre couplings’ ability to dampen vibrations and absorb shock loads helps ensure smooth and reliable operation of the connected equipment. The reduction of vibration and noise levels can lead to improved operating conditions and enhanced overall performance.

Due to these advantageous characteristics, tyre couplings are commonly used in various industrial applications, including pumps, compressors, fans, conveyors, mixers, and other rotating equipment. The coupling’s ability to dampen vibrations and handle shock loads contributes to the overall efficiency, safety, and reliability of the machinery, making it a preferred choice for many industrial processes.

What are the Potential Challenges of Using Tyre Couplings and How to Overcome Them?

While tyre couplings offer numerous advantages in various industrial applications, there are some potential challenges that users may encounter. Understanding these challenges and implementing appropriate solutions can help overcome them effectively. Here are some common challenges and ways to address them:

1. Temperature Limitations: Tyre couplings have specific temperature limits, and operating them beyond these limits can lead to premature wear and failure. To overcome this challenge, ensure that the operating temperature remains within the manufacturer’s recommended range. If the application involves extreme temperatures, consider using couplings with high-temperature resistant tyre materials.
2. Misalignment and Imbalance: Excessive misalignment or imbalance can cause uneven loading and accelerate tyre wear. Regularly inspect the machinery for misalignment issues and correct them promptly. Balancing the rotating components also helps in reducing the load on the tyre element, leading to longer coupling life.
3. Overload and Torque Spikes: Subjecting the coupling to overloads or sudden torque spikes can result in damage to the tyre element or other coupling components. Ensure that the coupling is adequately sized for the application and consider using torque-limiting devices to protect the coupling from sudden torque surges.
4. Chemical Exposure: In environments with aggressive chemicals, the tyre material may degrade or experience accelerated wear. Choosing a chemically resistant tyre material or providing additional protection, such as covers or guards, can help mitigate the effects of chemical exposure.
5. Lubrication and Maintenance: Tyre couplings generally require little maintenance. However, proper lubrication of the coupling and periodic inspections are essential to ensure optimal performance. Follow the manufacturer’s guidelines for lubrication intervals and inspection procedures.
6. Environmental Contaminants: Dirt, debris, and other environmental contaminants can accumulate in the coupling’s teeth or elastomeric element, leading to increased wear. Regularly clean the coupling and protect it from external contaminants to extend its service life.
7. Shaft Movement and End Float: Excessive shaft movement or end float can cause the coupling to bind or lead to premature failure. Properly secure the shafts and use appropriate coupling designs that can accommodate the required axial movement, if applicable.
8. Selection and Installation: Incorrect coupling selection or improper installation can lead to performance issues. Work closely with coupling manufacturers or experts to select the right coupling type and size for the application. Follow the manufacturer’s installation guidelines carefully to ensure proper coupling operation.
9. Environmental Conditions: Extreme environmental conditions, such as high humidity or aggressive outdoor environments, may affect the coupling’s performance. Select couplings with suitable protective features or take preventive measures, such as applying corrosion-resistant coatings, to enhance the coupling’s durability.

By addressing these potential challenges and following best practices in coupling selection, installation, and maintenance, users can maximize the reliability, efficiency, and service life of tyre couplings in their industrial applications.
