• Diagnostics of operational state of blading platforms – Automated Blading Control System (ABCS) SKALA

• Continuous monitoring of mechanical state of each stage blade (several stages) in the process of axial turbomachine operation.
• Timely detection of damages in blade system. :
  • cracks in working blades;
  • breaks in wire ties;
  • breaks in the periphery of the blades.
• Continuous monitoring of vibration level of each stage blade (several stages) in the process of axial turbomachine operation.
• Prompt warning of the unit personnel about detected damage of a platform with a description of the damage and indicating the appropriate blade number and step number.

• Diagnostics of operational state of blading platforms – Automated Blading Control System (ABCS) SKALA-BP

• Continuous monitoring of mechanical state of platforms at each stages in the process of turbine unit operation.
• Timely detection of damages in blading platforms.
• Prompt warning of the unit personnel about detected damage of a platform.

• Fatigue tests of blades (test rig investigations)

• Evaluation of fatigue strength endurance for blades of steam and gas turbines.
• Evaluation of quality of blade recovery after repair.
• Comparative evaluation of service life for blades made of various materials according to various procedures, etc.

• Electromagnetic treatment (demagnetization) of units and parts of the turbine plant in the repair process

Demagnetization is performed to prevent electrical erosion damages of guide bearings from monopolar electromotive forces.

• System of Operational Control for Electromagnetic State of Turbine Equipment

The system is designed for continuous operational diagnostics of electromagnetic state for turbine plant and timely detection of the following:

• improper operation of current collector;
• unallowable low resistance of journal insulation of insulated guide bearings;
• unallowable low resistance of insulation of oil films;
• occurrence of rotor current short circuit loops.

• Instrumentation of rotating equipment by strain gages for investigation

The laboratory has design a rotating equipment strain gauge testing system. The system is designed for strain gauge testing – evaluation of strain-stress state of an object, evaluation of amplitude-frequency response of blades – using strain gauges.

• Remote temperature measurement system for rotating objects

The department has developed a remote temperature measurement system for moving objects that utilizes proprietary pyrometric sensors.

• Shaft Train Torsion Measurement System

The systems is designed for:

• continuous monitoring of twisting angle of rotor between cross-sections in the process of turbine operation;
• timely detection of damages, such as:
  
  • circumferential cracks in the rotor body;
  • shaft damages in the diagnosed sections.

The operating principle of the system is based on utilization of discrete phase method and readings of inductive transducers.

This method has advantages over shaft torsion measurement method that utilizes torque measurement couplings, which are based on strain gauge transducers.

Advantages of our shaft train torsion measurement system:

• durability – there are no wear parts;
• simplicity of installation – no need to break the line of shafting;
• the evaluation of twisting takes into consideration such factors as floating and misalignment of shaft in guide bearings, which allows measuring the twisting value within the accuracy of 5 arc minutes.
