Flowserve is a multi-national industrial pump manufacturer having a large profile of pump variants for various applications; one of high pressure / high flow rate pump was investigated for its resonance related performance issues; using advanced tools of order tracking combined with Modal tools, problems were identified and RCA were conducted. Results are shared with the customer and further investigations are in progress
2-day training program on advanced basics of Noise & Vibrations was conducted at the Radisson Hotel in Bangalore; as normal to all our training programs, the limited seat course got filled up no sooner it was announced. This training program included both the basics part and other advanced tools used for N&V assessments. The participant response was overwhelming.
One of the large banquet and convention centre coming up in the IGI airport area in New Delhi wanted assessment of ground borne vibrations and airborne noise to the structure. Two primary sources were attributed to the cause, the metro rail operations in the tunnel passing nearby and the aircrafts operating right over the project area. Detailed particle velocity survey at the project site were conducted to determine the severity of vibrations.

The National facility for Nano Engineering at the Indian Institute of Science initiated assessment of noise and vibrations in their precision laboratory. This activity is of very high importance as many instrumentation in the laboratory are extremely sensitive to vibrations and acoustic energy. NV Dynamics conducted these tests and produced results; some key inputs on vibration mitigation plans were also recommended.
