Hydraulic Dynamometers Industry Information

Hydraulic Dynamometers

Hydraulic dynamometers are used to measure the force, torque, and power produced by different types of engines, motors, and other varieties of rotating movers. Power is capable of being calculated by measuring rotational speed. If a dynamometer measures liquids (such as oil or water) as a medium of power, the dynamometer is then considered to be hydraulic.

Applications of Hydraulic Dynamometers

Hydraulic dynamometers are commonly used in these industries:

  • Marine Engineering
  • Power Production
  • Automotive
  • Aerospace Design
  • Performance Racing
  • Mining Industry
  • Electric Motor Generators

Another word for hydraulic dynamometer is "dyno." These devices are also commonly referred to as water brake dynamometers. Some other industrial applications of water brakes include data readings in large trucks, off road vehicles, military vehicles, recreational vehicles, and mining equipment. The use of these dynamometers in recreational vehicles is also sometimes necessary to provide drivers with certain data readings they require to safely operate their vehicles and machines. Water brake dynamometers are another highly useful device that can be put to many uses within vehicles.

Hydraulic Dynamometer Design

Some materials used in the construction of dynamometers include aluminum alloys and stainless steel. Aluminum is a lightweight material that is useful for many reasons, including portability and weight. Stainless steel is corrosion-resistant, durable, and strong. There are many different parts at play with these types of dynamometers and it is imperative that they are all working in sync. Many dynamometer constructors adhere to strict regulations and guidelines in order to ensure their products meet strict quality standards.

A good company that constructs and sells these types of dynamometers also may sell any parts and accessories that may be needed in the future. This can make the repair and upkeep of dynamometers a simpler process for consumers. Many companies maintain an inventory of parts for repairs, consumable replacements, and spares. There are also certain accessories that may be required for dynamometer testing. Some of these include pressure transducers, flow turbines, oxygen sensors, and blow-by meters. A good company will have these accessories readily available as well. These departments may also have any product manuals that consumers will require.

How Hydraulic Dynamometers Work

A dynamometer measures power based on the speed rotation of disks and shafts inside of a casing. To cause rotation, liquid flows into hollow grooves that exist between the shafts and disks. The liquid rotates in a spiral motion, causing the unit to push against the outer casing. Applied brakes prevent the casing from moving, which is how the pressure is gauged. Their rotational speed is then measured to give a power output reading. The speed and force with which the shafts and disks turn will vary depending on the amount of pressure applied to them by the movement of liquid.

The rotating disks are mounted inside of a casing that surrounds all of the components. The component that measures this data is called a load cell. The load cell is usually located on the arm of the dynamometer. A signal is transmitted by the load cell to a load cell amplifier. Additionally, an analog water valve supplies control command through the use of an electronic transducer. This transducer converts the electric signal proportionally to air quantity supply to the valve. The fill level of the hydraulic dynamometer and the consequent load is then controlled by a water outlet valve. This water outlet valve is operated by a closed loop electro-hydraulic system.

Benefits of Using Hydraulic Dynamometers

A well-constructed dynamometer can drive productivity and ensure uptime with systems that deliver the best overall value for validations, diagnostics, engine break-ins, and many other important processes. A great dynamometer can ensure a quicker return on a consumer's investments. Well-constructed dynamometers can also increase accuracy in areas like off-road vehicles, large trucks, and military equipment. Precise, robust, and repeatable testing is a feature consumers will appreciate and come to depend on. Some dynos even work well under extremely rough operating conditions, which can be beneficial to consumers in many situations.

Points to Consider When Purchasing Hydraulic Dynamometers

In certain cases, it is extremely important that consumers regularly calibrate their dynamometers. This is mainly true for dynamometers used in the power and marine engineering industries. This will ensure accurate test results. When data is collected from these types of dynamometers that seems questionable, it may well be time for a re-calibration. Checking the sensors would be a good idea. Calibration is crucial if consumers want correct readings regarding temperature, pressure, voltage, frequency, and fluid flow.

The product designer that the dynamometer was purchased from can walk consumers through the calibration process. Many companies even offer calibration as a standard service. Not all dynamometers require calibration, but the ones that do must be serviced at regular intervals. Consumers may find these types of calibration services convenient and helpful when it comes time for dynamometers to be calibrated.
