Getzner to present its vibration isolation system at the POWER-GEN trade

The Austrian company Getzner, experts for vibration isolation, recently installed their innovative solutions at two thermal power plants by Essar Power in Salaya/Gujarat and Mahan/Madhya Pradesh. “Designers of plants often face the challenge of fitting the power plant machinery in the limited space available. There is a great risk of vibrations generated from this machinery getting transferred to the structural elements of the building or to the other machine foundations”, explains Sanjay Risbood, CEO of Getzner India Pvt. Ltd. 

 

In the Essar Power plants, Getzner installed its vibration isolation system to isolate the motor driven boiler feed pump (MDBFP) foundations as well as the seal air fan (SAF) foundations. At the 1200 MW Salaya plant in Gujarat, engineers faced the problem that the deep-seated block foundations of the pump are located very near to structural columns of the turbine generator building. “To eliminate the risk of structural damage to these columns, it was necessary to isolate the foundation from the neighbouring structure”, says Risbood. The boiler feed pump weighs 276 tons and has four different units including the motor, a hydraulic coupling, pump and others. “The units have different operational speeds ranging from 1490 rpm to 5254 rpm. All of this makes a high-end vibration isolation crucial.”

 

Patented solutions: Sylomer® and Sylodyn®:

 

Getzner has been providing its vibration isolation solution based on microcellular polyurethane elastomer (MPE) products for more than 40 years: Sylomer® and Sylodyn®. The uniqueness of MPE is that it both isolates and damps. “At the Salaya plant, we calculated the requirements and designed a vibration isolation system with a 50mm thick layer of MPE below the foundation. The solution comprised Sylomer® of different grades to tackle varying load distribution across the whole length and width of the foundation block”, informs Sanjay Risbood. After the installation in the year 2010, tests were carried out in 2013, confirming the good performance and reliability. The simplicity of design and installation as well as the maintenance free operation are other key assets.

 

Getzner will present its innovative vibration isolation solutions at the POWER-GEN trade show in New Delhi (Booth number 1120-1121).
