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 Maintenance Requirements for Rigid Couplings?

Rigid couplings are known for their simplicity and low maintenance requirements. Since they do not have moving parts or flexible elements, there are minimal wear and tear issues. However, some maintenance considerations for rigid couplings include:

1. Regular Inspection: It is essential to perform periodic inspections of the rigid couplings to check for any signs of wear, damage, or misalignment. Regular inspections can help identify potential issues early and prevent further problems.

2. Shaft Alignment: Proper shaft alignment is critical for rigid couplings. During installation or whenever maintenance work is performed on the connected machinery, the shaft alignment must be checked and adjusted if necessary. Misalignment can lead to premature coupling failure and cause additional stress on connected equipment.

3. Lubrication: Most rigid couplings do not require lubrication since they have no moving parts. However, some special designs or large-sized couplings may have set screws or other fasteners that require lubrication. It is essential to follow the manufacturer’s guidelines regarding lubrication, if applicable.

4. Corrosion Protection: In corrosive environments, protecting the rigid couplings from corrosion is crucial. This can be achieved through the use of corrosion-resistant materials or coatings.

5. Periodic Re-tightening: If the rigid coupling uses set screws or other fasteners, periodic re-tightening may be necessary to maintain the integrity of the connection. This is particularly important in applications with high vibrations or heavy loads.

6. Temperature Considerations: Rigid couplings may experience thermal expansion or contraction, especially in high-temperature environments. It is essential to consider the thermal expansion characteristics of the coupling material and the connected shafts to ensure proper functioning under varying temperatures.

7. Professional Maintenance: In complex systems or critical applications, it is advisable to seek professional maintenance and alignment services. Expert technicians can ensure proper installation, alignment, and maintenance of rigid couplings, reducing the risk of unexpected failures.

Overall, rigid couplings are designed for reliability and longevity, and proper maintenance practices can further enhance their performance and lifespan. Regular inspections and alignment checks are vital for identifying and addressing potential issues before they escalate into costly problems.

What Role Does a Rigid Coupling Play in Reducing Downtime and Maintenance Costs?

A rigid coupling can play a significant role in reducing downtime and maintenance costs in mechanical systems by providing a robust and reliable connection between two shafts. Here are the key factors that contribute to this:

1. Durability and Longevity: Rigid couplings are typically made from high-quality materials such as steel or stainless steel, which offer excellent durability and resistance to wear. As a result, they have a longer service life compared to some other types of couplings that may require frequent replacements due to wear and fatigue.

2. Elimination of Wear-Prone Components: Unlike flexible couplings that include moving parts or elements designed to accommodate misalignment, rigid couplings do not have any wear-prone components. This absence of moving parts means there are fewer components that can fail, reducing the need for regular maintenance and replacement.

3. Minimization of Misalignment-Related Issues: Rigid couplings require precise shaft alignment during installation. When installed correctly, they help minimize misalignment-related issues such as vibration, noise, and premature bearing failure. Proper alignment also reduces the risk of unexpected breakdowns and maintenance requirements.

4. Increased System Efficiency: The rigid connection provided by a rigid coupling ensures efficient power transmission between the two shafts. There is minimal power loss due to flexing or bending, leading to better overall system efficiency. This efficiency can result in reduced energy consumption and operating costs.

5. Low Maintenance Requirements: Rigid couplings generally require minimal maintenance compared to some other coupling types. Once properly installed and aligned, they can operate for extended periods without needing frequent inspection or adjustment.

6. Reduced Downtime: The robust and reliable nature of rigid couplings means that they are less likely to fail unexpectedly. This increased reliability helps reduce unscheduled downtime, allowing the mechanical system to operate smoothly and consistently.

7. Cost-Effective Solution: While rigid couplings may have a higher upfront cost than some other coupling types, their long-term durability and low maintenance requirements make them a cost-effective solution over the life cycle of the equipment.

In conclusion, a rigid coupling’s ability to provide a durable and dependable connection, along with its low maintenance requirements and efficient power transmission, contributes significantly to reducing downtime and maintenance costs in mechanical systems.

What is Elastomeric Coupling and How Does It Work in Mechanical Systems?

An elastomeric coupling is a type of flexible shaft coupling that uses an elastomeric material, typically rubber or polyurethane, to connect two shafts and transmit torque between them. The primary purpose of elastomeric couplings is to compensate for misalignments between the shafts while dampening vibrations and shocks in mechanical systems.

Construction and Working Principle:

Most elastomeric couplings consist of two hubs with a flexible element in between. The flexible element is made of high-quality elastomeric material, which is molded or bonded to the hubs. The elastomeric material is designed to be both torsionally flexible and durable.

When torque is applied to one shaft, the flexible element deforms and absorbs the misalignment between the shafts, allowing the coupling to compensate for angular, parallel, and axial misalignments. This flexibility is crucial for preventing undue stress on the connected equipment and increasing the coupling’s lifespan.

Key Features and Advantages:

1. Misalignment Compensation: Elastomeric couplings can handle small degrees of misalignment, making them suitable for applications where precise alignment is challenging or subject to change over time.

2. Vibration Dampening: The elastomeric material absorbs vibrations and shocks, resulting in reduced noise and improved smoothness of operation.

3. Fail-Safe Design: Elastomeric couplings have a fail-safe design, where if the elastomeric element were to fail, the coupling could still transmit torque without completely breaking down.

4. Simple and Economical: Elastomeric couplings are relatively simple in design, easy to install, and cost-effective compared to some other coupling types.

5. Maintenance-Free: In general, elastomeric couplings require minimal maintenance, making them a popular choice in various industries.

Applications:

Elastomeric couplings find applications in a wide range of industries and mechanical systems, including:

  • Pumps and compressors
  • Conveyor systems
