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.

Retrofitting Roller Chain Couplings for Improved Performance

Yes, roller chain couplings can be retrofitted into existing systems to improve performance and enhance power transmission capabilities. Retrofitting is a cost-effective way to upgrade the coupling system without the need for significant modifications to the existing machinery.

When considering a retrofit with roller chain couplings, it is essential to ensure that the new couplings are compatible with the existing shaft sizes and operating conditions. The dimensions of the roller chain couplings should match the space available in the system, and the torque and speed ratings should meet or exceed the requirements of the application.

The advantages of retrofitting with roller chain couplings include:

• Increased Torque Capacity: Roller chain couplings can handle higher torque loads compared to some other coupling types, providing improved power transmission capabilities.
• Better Misalignment Tolerance: Roller chain couplings can accommodate both angular and parallel misalignments, reducing stress on the connected equipment and extending its service life.
• Shock Load Absorption: The flexibility of roller chain couplings allows them to absorb shock loads, protecting the drivetrain and other mechanical components from sudden impacts.
• Reduced Downtime: Retrofitting can be a quick and straightforward process, minimizing downtime during the upgrade.

Before proceeding with the retrofit, it is essential to consult with coupling manufacturers or engineering experts to ensure the proper selection and installation of roller chain couplings. Additionally, regular maintenance and inspections are crucial to ensure continued optimal performance and reliability of the retrofitted coupling system.

Roller Chain Couplings in Applications Requiring Frequent Starts and Stops

Yes, roller chain couplings can be used in applications that require frequent starts and stops. These couplings are designed to provide reliable torque transmission and accommodate misalignments even during repetitive and rapid motion changes.

The key features that make roller chain couplings suitable for such applications include:

• Durable Construction: Roller chain couplings are typically constructed from high-quality materials, such as steel or stainless steel, which offer excellent durability and resistance to wear and fatigue.
• Shock Absorption: The flexible nature of roller chain couplings allows them to absorb shocks and vibrations that may occur during frequent starts and stops, preventing damage to connected equipment.
• Backlash Minimization: Roller chain couplings are designed to minimize backlash, which is the amount of free play between the connected shafts. This feature ensures precise and reliable torque transmission, even when starting and stopping repeatedly.
• Smooth Operation: The chain and sprocket design of roller chain couplings allows for smooth operation, reducing jarring movements during starts and stops.
• Misalignment Tolerance: Roller chain couplings can accommodate angular and parallel misalignments between shafts, which is essential in applications where frequent starts and stops may lead to slight shifts in the alignment.
• Easy Maintenance: Roller chain couplings are relatively easy to maintain, making them suitable for applications requiring frequent operation. Regular inspection and lubrication can help ensure optimal performance.

It is important to select the appropriate size and type of roller chain coupling based on the specific requirements of the application, including the expected frequency of starts and stops. Proper maintenance and monitoring of the coupling’s condition can help prolong its lifespan and ensure smooth operation even in demanding applications with frequent motion changes.

How to Select the Right Roller Chain Coupling for Specific Machinery or Equipment?

Selecting the right roller chain coupling for specific machinery or equipment involves considering several important factors. Here’s a step-by-step guide:

1. Torque Requirements: Determine the torque that the coupling needs to transmit between the driving and driven shafts. This will help you choose a coupling with the appropriate torque capacity for your application.
2. Speed: Consider the operating speed of the machinery. Higher speeds may require special high-speed roller chain couplings designed to handle the centrifugal forces.
3. Misalignment: Evaluate the degree of misalignment between the shafts. Different roller chain couplings have varying misalignment capabilities, so choose one that can accommodate the misalignment in your application.
4. Space Constraints: Measure the available space for the coupling. Some roller chain couplings are compact and may be suitable for applications with limited space.
5. Environmental Conditions: Take into account the operating environment, including temperature, humidity, and exposure to contaminants. Choose a coupling material and finish that can withstand the environmental conditions.
6. Load Characteristics: Assess the nature of the loads and any shock or vibration present in the system. For heavy-duty or shock-loaded applications, consider using heavy-duty roller chain couplings.
7. Alignment Maintenance: Evaluate the ease of alignment maintenance. Some couplings may require more frequent checks and adjustments to maintain proper alignment.
8. Backlash: Determine the level of backlash permissible in the application. Certain couplings may introduce minimal backlash, which is critical in precision systems.
9. Cost: Consider the overall cost, including the initial purchase price and long-term maintenance expenses. Opt for a roller chain coupling that provides the best value for your specific needs.

By carefully considering these factors, engineers and designers can identify the most suitable roller chain coupling that ensures reliable and efficient power transmission for their machinery or equipment.
