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.

Industry Standards and Guidelines for Selecting and Installing Encoder Couplings

While there are no specific industry standards exclusively focused on encoder couplings, various general standards and guidelines related to couplings and motion control systems can be applied. These standards ensure proper selection, installation, and operation of encoder couplings:

1. ISO Standards: ISO (International Organization for Standardization) has developed standards related to couplings, such as ISO 14691 for flexible couplings and ISO 15364 for gear couplings. Although not specific to encoder couplings, these standards provide guidance on aspects like dimensions, tolerances, and testing methods.

2. Manufacturer Recommendations: Encoder coupling manufacturers often provide guidelines for selecting and installing their products. These guidelines include information on torque ratings, misalignment capabilities, and installation procedures specific to their coupling designs.

3. Motion Control Associations: Organizations such as the Motion Control & Motor Association (MCMA) provide resources and best practices for selecting and integrating motion control components, including encoder couplings. They offer insights into achieving optimal performance, accuracy, and reliability.

4. Machinery Safety Standards: Depending on the application, machinery safety standards such as ISO 13849 or ANSI B11.19 may need to be considered. These standards ensure the safe integration of motion control systems and related components.

5. OEM and System Requirements: The original equipment manufacturer (OEM) or specific system requirements for the machinery or automation setup should also be considered when selecting and installing encoder couplings. These requirements may include environmental conditions, space limitations, and performance expectations.

When selecting and installing encoder couplings, it’s essential to follow the guidelines provided by the coupling manufacturer and consider relevant industry standards. Additionally, consulting with experts in the field of motion control and automation can help ensure that the chosen encoder coupling meets the specific needs of the application and complies with safety and performance standards.

Types of Encoder Couplings Tailored for Specific Applications

Encoder couplings come in various types, each tailored to suit specific applications and requirements:

1. Beam Couplings: These couplings use flexible beams to transmit motion and accommodate misalignments. They are ideal for applications requiring high precision and low backlash.

2. Bellows Couplings: Bellows couplings have accordion-like bellows that provide high torsional stiffness while allowing axial and angular misalignment compensation. They are commonly used in vacuum environments.

3. Oldham Couplings: Oldham couplings use a three-piece design to transmit motion. They provide high misalignment capacity while maintaining accurate motion transmission.

4. Disc Couplings: Disc couplings consist of thin metal discs that provide torsional stiffness and minimal backlash. They are suitable for high-speed and high-torque applications.

5. Flexible Shaft Couplings: These couplings use a flexible element, such as elastomer or rubber, to accommodate misalignments and dampen vibrations. They are versatile and used in various industries.

6. Miniature Couplings: Designed for small-scale applications, miniature couplings provide precise motion control in compact spaces, such as robotics and medical devices.

7. High-Torque Couplings: These couplings are built to handle high torque loads, making them suitable for heavy-duty industrial applications.

8. Magnetic Couplings: Magnetic couplings use magnets to transmit motion without physical contact. They are used in applications requiring hermetic sealing or where avoiding direct contact is necessary.

9. Encoder-Integrated Couplings: Some couplings come with built-in encoders for direct position sensing. These are convenient for applications where space is limited or where separate encoders are not practical.

10. Shaft Locking Mechanisms: Some couplings feature mechanisms that lock the shafts in place, providing additional security against shaft slippage.

The choice of encoder coupling type depends on factors like the level of misalignment, torque requirements, speed, space limitations, and specific application needs.
