Diaphragm & Seal Ring

Diaphragm & Seal Ring

This device is used to increase thermal efficiency by transferring a flow of a suitable amount of high-temperature,
high-pressure steam to the power during the process of converting high-temperature, high-pressure heat energy into
kinetic energy.

Seal Ring / Packing Ring/ Labyrinth Ring / Spill Strip

These devices minimize steam leakage between the rotor and diaphragm (steel and bronze materials are used depending on the temperature and pressure at each row).

• 

  This device minimizes steam leakage between the bucket edge and diaphragm.

• 

  This device minimizes steam leakage between the gland box and diaphragm.

• 

  This device reduces steam flow speed inside the packing ring during operation to enhance rotor stability.
