 SPLIT SEALS FOR TURBINE SHAFT SEALING

• Experts say that poor reliability and significant
  leakage are the two biggest concerns in turbines
  and hydropower applications.
• In the conventional system, various types
  of primary shaft sealing are used polymer radial
  seals, segmented radial seals, segmented axial
  seals, and so on.
• When multiple sump pumps are used, they add to
  the operations and maintenance costs.
• Split seals play a phenomena role in reducing
  annual expenses. They, in a true sense,
  revolutionize the operations.
• Split seals are critical components that ensure
  reliable operations. There have been several
  studies that prove the effectiveness of split
  seals for main shaft sealing.

IT IS EASY TO INSTALL SPLIT SEALS

• Installation of a split seal doesnt take much
  time. In fact, it can be done in a few hours.
  There is no need to dismantle the turbine. The
  components can be easily fitted the shaft.
• Since the maintenance need is minimal and no
  packing readjustments are required, people find
  split seals very much convenient.

WHAT MAKES SPLIT SEALS EFFECTIVE?

• As compared to the standard non-split design, it
  is a significant challenge to design mechanical
  split seals. However, it is worth putting efforts
  into it because of the incredible benefits.
• The seal faces are square and flat. They are
  manufactured as the normal non-split face and
  then lapped to achieve flatness of their faces.
• Once they are checked for flatness, the face is
  split into two halves. These halves fit together
  perfectly.

• Thus, there is no need to create a seal ring to
  match the segments.
• Engineers make sure that the profile of the ring
  is made so carefully that the mating seal faces
  are always in contact with each other. Even if
  there are pressure and temperature fluctuations,
  the faces remain unaffected with it.
• The reliability of the split seal is very high.

ROLe OF FILTRATION IN DETERMINING THE SEAL
RELIABILITY

• It is mandatory to filter the flush water so that
  physical impurities or abrasive material doesnt
  enter the shaft seal.
• The flush water has to be filtered to under the
  size of 10 microns.
• Since the filtration system is supposed to filter
  millions of liters of water, the filtration
  system has to be 100 reliable and dependable.

8

• The filtration system delivers the flush water in
  the required quantity to the seal while the
  filtration cleaning system is deployed.
• Always check the filtration needs and flush
  leakage system before installing the filtration
  device.
• Appropriate design features need to be taken care
  for better performance.
