Система контроля зазоров

Optical system for clearance control

Purpose:
  • Non-contact multichannel measurement of diaphragm's deformations and clearances while centering the high-pressure, middle-pressure and low-pressure turbine setting.
  • Precise non-contact multichannel measurement of clearances while making the repair works.
  • Measurement of angular positions.


Cостав:
  • блок измерения зазоров
  • комплект измерительных датчиков
  • блок аккумуляторного питания
  • датчик углового положения


Application area:
  • Centering of the steam turbine setting.
  • High-accuracy non-contact clearances measurement while making the repair works.

При выполнении центровочных работ система контроля зазоров используется совместно с борштангой (механическим фальшвалом), обеспечивающей установку измерительных датчиков в проточной части турбоагрегата.


The system for clearance monitoring provides::
  • non-contact multichannel clearance measurement while making the centering works of the turbine setting;
  • measurement of the boring bar rotation angles;
  • non-contact clearances measurement while making the repair works of the rotor-type equipment.
