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.

fluid drive coupling

Are there specific torque and speed limits for different fluid drive coupling designs?

Yes, different fluid drive coupling designs have specific torque and speed limits that determine their suitable applications and performance capabilities. These limits are influenced by the coupling’s design, construction, and the type of hydraulic fluid used. Here are the key factors that contribute to torque and speed limits in fluid drive couplings:

  • Coupling Size and Design: The physical size and design of the fluid drive coupling play a significant role in determining its torque capacity. Larger couplings with robust construction can generally handle higher torque loads than smaller couplings.
  • Hydraulic Fluid Type: The type and viscosity of the hydraulic fluid used in the coupling affect its torque transmission capabilities. Different fluid types may have varying coefficients of friction, which impact the torque capacity of the coupling.
  • Fluid Fill Level: The amount of hydraulic fluid filled in the coupling can influence its torque capacity. Proper fluid fill levels are essential for optimal coupling performance and torque transmission.
  • Speed Range: The speed range of a fluid drive coupling is determined by its design and the hydraulic fluid’s properties. Some couplings may have limitations at high rotational speeds due to centrifugal forces and fluid dynamics.
  • Operating Temperature: The operating temperature of the fluid drive coupling affects the hydraulic fluid’s viscosity, which in turn impacts the coupling’s torque transmission efficiency and overall performance.
  • Application Specifics: The specific application requirements, such as load variations, start-up conditions, and duty cycles, also influence the torque and speed limits of the fluid drive coupling.

Manufacturers provide torque and speed ratings in their coupling specifications to guide users in selecting the appropriate coupling for a particular application. These ratings indicate the maximum torque and rotational speed that the coupling can handle safely and effectively without risking damage or performance issues.

It is essential to carefully match the torque and speed requirements of the power transmission system with the fluid drive coupling’s torque and speed limits. Operating the coupling within its specified limits ensures optimal performance, extended service life, and enhanced safety of the power transmission system.

If the application demands higher torque or speed capabilities than a standard fluid drive coupling can provide, it is advisable to consult with coupling manufacturers or fluid power engineers to explore custom-designed or specialized couplings that can meet the specific requirements.

Can Fluid Drive Couplings Be Retrofitted Into Existing Systems to Improve Performance?

Yes, fluid drive couplings can be retrofitted into existing systems to improve performance and achieve various benefits. Fluid drive couplings, also known as hydraulic couplings, hydrodynamic couplings, or fluid couplings, are highly versatile and can be used in a wide range of applications.

Retrofitting a fluid drive coupling into an existing system offers several advantages:

  • Reduced Shock Loads: Fluid drive couplings have the ability to cushion shock loads and dampen torsional vibrations. By retrofitting a fluid coupling, the system can experience smoother starts and stops, reducing stress on the connected equipment and improving overall system reliability.
  • Overload Protection: Fluid couplings act as torque limiters, providing protection against sudden torque spikes and overloads. This helps safeguard sensitive machinery and prevents damage to the system during unexpected events.
  • Energy Savings: Fluid drive couplings allow for gradual engagement, which reduces power peaks during starting and stopping operations. This leads to energy savings, especially in applications where frequent starts and stops are required.
  • Flexible Power Transmission: Fluid couplings can accommodate slight misalignments between the driving and driven shafts, making them suitable for retrofitting into systems with existing misalignment issues.
  • Increased System Lifespan: By reducing mechanical stresses and wear on the connected equipment, fluid drive couplings can extend the overall lifespan of the system, leading to lower maintenance costs and increased productivity.
  • Smooth and Quiet Operation: Fluid drive couplings provide smooth and quiet power transmission, reducing noise levels and enhancing the comfort of operators and personnel working near the equipment.

When retrofitting a fluid drive coupling, it is essential to consider factors such as the specific application requirements, the torque and speed characteristics of the existing system, and the compatibility of the coupling with the connected equipment. Proper alignment and installation are also crucial to ensure optimal performance and longevity.

Overall, retrofitting fluid drive couplings into existing systems can be a cost-effective and beneficial solution to enhance performance, improve efficiency, and protect valuable machinery in various industrial applications.

How do fluid drive couplings accommodate misalignment and protect against overload during operation?

Fluid drive couplings are designed to accommodate misalignment between the driving and driven shafts, as well as provide protection against overload conditions during operation. The key mechanisms that enable these features are as follows:

  • Misalignment Accommodation: Fluid drive couplings utilize a hydrodynamic principle to transfer power between the driving and driven shafts. The hydraulic fluid within the coupling creates a fluid film that separates the impellers (pump and turbine) of the coupling. This fluid film allows the impellers to rotate independently of each other and provides some level of misalignment accommodation. As a result, the fluid drive coupling can tolerate small amounts of axial and angular misalignment between the shafts without causing excessive wear or damage.
  • Slip Mechanism: In fluid drive couplings, the impellers are designed to slip relative to each other under certain conditions. During start-up or when the driven shaft encounters a sudden overload, the fluid drive coupling allows a controlled amount of slip between the impellers. This slip absorbs the excess energy and prevents shock loads from transmitting to the machinery. The slip mechanism acts as a protective feature, preventing damage to the coupling and the connected components in the power transmission system.
  • Overload Protection: The slip mechanism in fluid drive couplings also serves as an overload protection mechanism. If the load on the driven shaft exceeds the coupling’s capacity, the impellers will slip to prevent the driving shaft from stalling and absorbing the excessive load. This overload protection prevents damage to the power transmission system, providing a safety measure against sudden and unexpected overloads.
  • Gradual Torque Transmission: Fluid drive couplings offer gradual torque transmission, especially during start-up. As the driving shaft accelerates, the hydraulic fluid transfers torque to the driven shaft smoothly. This gradual engagement helps reduce shock loads on the system, protecting the machinery from excessive stresses and ensuring a longer operational life.

By incorporating these design features, fluid drive couplings enhance the reliability, efficiency, and safety of power transmission systems. The ability to accommodate misalignment and provide overload protection makes fluid drive couplings suitable for various applications, where mechanical flexibility and safety are essential requirements.

However, it’s important to note that while fluid drive couplings offer misalignment accommodation and overload protection to a certain extent, excessive misalignment or continuous overload conditions can still lead to premature wear and reduce the coupling’s overall performance. Regular maintenance and monitoring of the fluid drive coupling’s condition are necessary to ensure it continues to operate optimally and contributes to the efficient functioning of the power transmission system.
