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.

fluid drive coupling

What are the different fluid media used in fluid drive couplings, such as oil or water?

Fluid drive couplings can use various types of hydraulic fluids as the medium to transmit torque between the driving and driven elements. The choice of fluid media depends on the specific application requirements and the operating conditions. Some common fluid media used in fluid drive couplings include:

  • Oil: Mineral oil, synthetic oil, or a blend of various oils are commonly used as hydraulic fluids in fluid drive couplings. These oils offer good lubrication properties and thermal stability, making them suitable for various industrial applications. Oil-based fluid drive couplings are often preferred for heavy-duty and high-temperature applications.
  • Water-Glycol: Water-glycol mixtures are widely used as hydraulic fluids in fluid drive couplings that require fire-resistant properties. These fluids are commonly used in industries where fire hazards are a concern, such as steel mills and foundries.
  • Water-Oil Emulsions: Emulsions of water and oil are used in certain fluid drive couplings, especially in applications where fire resistance and cooling properties are essential. Water-oil emulsions provide both good lubrication and effective heat dissipation capabilities.
  • Water: In some specific applications, plain water is used as the hydraulic fluid in fluid drive couplings. Water offers excellent cooling properties and is suitable for applications where there is no risk of freezing or where fire resistance is not a primary concern.
  • Biodegradable Fluids: Biodegradable hydraulic fluids, such as vegetable-based oils or synthetic esters, are employed in environmentally sensitive applications. These fluids are biodegradable and offer good lubrication properties while minimizing environmental impact.
  • Specialty Fluids: Depending on the specific requirements of niche applications, other specialty hydraulic fluids with unique properties may be used in fluid drive couplings. These specialty fluids are tailored to meet specific demands, such as extreme temperatures or aggressive operating environments.

The selection of the appropriate hydraulic fluid for a fluid drive coupling depends on factors like the operating temperature, load conditions, environmental considerations, and compatibility with the coupling’s materials. Manufacturers usually provide guidelines on the suitable fluid types and specifications for their specific fluid drive coupling models.

Regular monitoring and maintenance of the hydraulic fluid are essential to ensure optimal performance and to extend the service life of the fluid drive coupling. Fluid condition monitoring helps identify any signs of contamination or degradation, enabling timely fluid replacement or treatment as necessary.

It is crucial to follow the manufacturer’s recommendations regarding fluid type, fluid level, and fluid change intervals to ensure the fluid drive coupling operates efficiently and reliably in its intended application.

What are the standard sizes and specifications available for fluid drive couplings?

Fluid drive couplings come in a wide range of standard sizes and specifications to accommodate various mechanical power transmission applications. The sizes and specifications of fluid drive couplings are typically determined by the manufacturer and are based on industry standards and application requirements.

Some common standard sizes and specifications for fluid drive couplings include:

  • Shaft Diameter: Fluid drive couplings are available in various shaft diameter options to fit different shaft sizes of the driving and driven elements. Standard shaft diameters range from a few millimeters to several inches.
  • Power Rating: The power rating of fluid drive couplings indicates the maximum amount of power (torque and speed) the coupling can efficiently transmit. Power ratings can vary significantly based on the coupling’s size and design.
  • Speed Range: Fluid drive couplings are designed to operate within specific speed ranges. Some couplings are optimized for high-speed applications, while others are suitable for low-speed or variable-speed applications.
  • Torque Capacity: The torque capacity of a fluid drive coupling refers to the maximum amount of torque it can transmit without slipping. Torque capacity is an essential consideration for selecting a coupling that can handle the required load and torque demands of the application.
  • Operating Temperature Range: Fluid drive couplings are designed to operate within specific temperature ranges. The operating temperature range depends on the type of hydraulic fluid used and the materials used in the coupling’s construction.
  • Fluid Type: The type of hydraulic fluid used in the coupling can affect its performance and compatibility with the application. Various fluids, such as oils or water-based fluids, may be used depending on the specific requirements.
  • Environmental Protection: Some fluid drive couplings may offer additional environmental protection features, such as sealing mechanisms or corrosion-resistant coatings, to ensure reliable operation in harsh or challenging environments.

It is essential to carefully consider the specific requirements of the application when selecting a fluid drive coupling. Factors such as the power demands, operating speed, torque requirements, environmental conditions, and space limitations should be taken into account to ensure the chosen coupling is suitable for the intended application.

Manufacturers of fluid drive couplings can provide detailed product catalogs and specifications that assist in selecting the appropriate coupling based on the system’s needs. Consulting with coupling experts and specifying the application’s parameters will help ensure the right fluid drive coupling is chosen for optimal performance and reliability in the mechanical power transmission system.

fluid drive coupling

Can you explain the working principle of a fluid drive coupling and its advantages over other coupling types?

A fluid drive coupling, also known as a hydraulic coupling, is a type of coupling used to transmit power between two shafts in a machinery system. It operates on the principle of hydrodynamic power transmission, utilizing hydraulic fluid to transfer torque and rotational motion from the driving shaft to the driven shaft.

The working principle of a fluid drive coupling involves the following key elements:

  • Driving Impeller (Pump): The fluid drive coupling consists of a driving impeller, also called the pump, attached to the driving shaft. When the driving shaft rotates, it causes the driving impeller to rotate as well.
  • Driven Impeller (Turbine): The driven impeller, also known as the turbine, is connected to the driven shaft. As the fluid in the coupling circulates, it imparts rotational motion to the driven impeller.
  • Hydraulic Fluid: The coupling is filled with hydraulic fluid, typically oil. When the driving impeller rotates, it creates a flow of hydraulic fluid within the casing.

As the hydraulic fluid moves from the driving impeller to the driven impeller, it generates a hydraulic force that drives the driven impeller to rotate. This movement of fluid between the impellers allows the transfer of torque from the driving shaft to the driven shaft without any direct mechanical contact between them.

Advantages of Fluid Drive Coupling over other coupling types include:

  • Smooth Operation: Fluid drive couplings offer smooth and gradual acceleration, minimizing shock loads on the machinery and reducing wear on mechanical components. This results in improved system longevity and reduced maintenance requirements.
  • Torque Amplification: During start-up or when the driven shaft encounters resistance, fluid drive couplings can provide torque amplification, allowing the driven shaft to handle higher loads without stalling the driving shaft.
  • Overload Protection: Fluid drive couplings can slip under excessive load conditions, absorbing the excess energy and protecting the machinery from damage. This feature acts as a safety mechanism and prevents sudden overloads.
  • Speed Regulation: By adjusting the input speed of the driving shaft, fluid drive couplings can regulate the speed of the driven shaft. This feature is beneficial in applications where precise control of output speed is necessary.
  • No Mechanical Wear: Since fluid drive couplings do not have any physical contact between the driving and driven shafts, there is minimal mechanical wear, reducing the need for frequent maintenance and replacement of coupling components.
  • Isolation of Vibrations and Noise: Fluid drive couplings dampen vibrations and noise in the power transmission system, resulting in quieter operation and improved comfort in the surrounding environment.
  • High Misalignment Tolerance: Fluid drive couplings can accommodate axial and angular misalignments between the driving and driven shafts, reducing the risk of component failure due to misalignment issues.

Fluid drive couplings find application in various industries, including automotive, construction, industrial machinery, and marine, where they contribute to efficient power transmission, improved system performance, and enhanced safety during operation.

It’s essential to consider the specific requirements of the machinery system and the advantages offered by fluid drive couplings when selecting the appropriate coupling type for a particular application. Proper installation, maintenance, and monitoring of the fluid drive coupling ensure continued reliable and efficient operation of the machinery or equipment.
