How do you align a fluid coupling?

How do you align a fluid coupling?


  1. The driving machine must be mounted in its final position. The foundation bolts must be firmly tightened.
  2. Fit the flexible element in the connecting coupling.
  3. Push the motor up to the driven machine. To allow the motor to be correctly aligned, the feet should be adjusted by means of shims or foil plates.

How much oil is filled in the coupler of the fluid coupling?

The maximum allowable oil fill amounts to approximately 80% of the total capacity of the Fluid Coupling. This level should never be exceeded since overfilling may cause over pressure inside the coupling and damage to the seals.

What is the main function of fluid coupling?

Fluid coupling also known as hydraulic coupling is a hydrodynamic device which is used to transfer rotational power from one shaft to another by the use of transmission fluid. It is used in automotive transmission system, marine propulsion system and in industries for power transmission.

What are the advantages of fluid coupling?

Fluid couplings provide a controlled soft start up, helping to prevent shock loads and protect surrounding equipment. These couplings allow variable speeds and provide easy torque control.

What are the types of fluid coupling?

In practice there are two types of fluid couplings; Constant Filling, where the oil filling is fixed and variable filling also known as variable speed where the quantity of oil in the working circuit can be varied whilst running to give control over the amount of slip between the impeller and runner and so give speed …

What is the purpose of a coupling?

The basic function of all couplings is to transmit power, accommodate misalignment and compensate for axial movement (end movement of shafts). Sometimes, a coupling is asked to absorb shock or vibration. Selecting the right coupling depends on four basic conditions of shaft misalignment or movement.

What are the main component of fluid coupling?

The fluid coupling consists of a pump impeller (on the input shaft) and a runner (on the output shaft). Both impellers are housed in the same casing. The pump impeller pushes the fluid inside the casing (usually low-viscosity oil) towards the runner, which causes the output shaft to rotate.

Where is Vulcan Sinclair fluid drive coupling located?

The Valcan-Sinclair Fluid Coupling was commissioned and is running well. Clients Sulzer MC80-260 11 stage boiler feed pump had decreased in performance and was in need of an overhaul. Whilst in service on a plant in SA. This fluid coupling is situated between a Siemans three-phase motor and a 6”/8” 10 stage boiler feed pump.

What kind of motor does Vulcan Sinclair use?

Once arriving in WA we started the dismantling process, starting with the removal of the couplings and scoop tube assembly, tacking note of all measurements and full photo reports. The Valcan-Sinclair Fluid Coupling is a scoop trimming type of motor to pump variable speed coupling, it is a scoop trimming type of coupling.
