Expert is experienced in many areas of mechanical engineering. These areas include design and analysis, machine shop and assembly technologies, product testing and certification, third party approvals, special component procurement, research and development, equipment start-up and field troubleshooting, failure analysis, ISO 9000 quality system, expert witnessing and other areas. This experience is coming from expert's work for many years as manager and director of engineering of a manufacturing company. The primary product was custom engineered pumps and electric motors.
Expert has extensive background in pump engineering. He is proficient in the areas of pump design, manufacturing, application and operation. More specifically, the range of expertize includes pump operation in a pumping system, multiple pump operation, variable speed pump applications, hydraulic performance, pump testing (both at the factory and in the field), effects of piping hydraulics, out of range operation, system design, and installation issues. One important area of expertize is pump vibration. Pump vibration analysis and troubleshooting techniques developed by the expert over the years allow quick and accurate diagnostics of a vibration issue whether it has mechanical, hydraulic, or structural nature.
Array
A 2000 Hp centrifugal pump experienced out of specification vibration levels after installation. It was established by preliminary tests that there was a resonance condition excited by the vane passing frequency. Subsequent modal analysis revealed that the pump supporting frame made of steel beams had insufficient stiffness and was responsible for a number of mode shapes that had been excited within the pump operating speed range. After a computer simulation was performed a solution was proposed and implemented to modify the support by adding concrete around the beams. The solution has drastically reduced vibration by eliminating the resonance condition.To reduce resonance vibration in a large motor a dynamic vibration absorber was proposed as a solution. Additional research was necessary as the motor was operating with variable speed and the absorber had to be designed to accommodate the motor's speed range. The resulting design allowed independent tuning of all absorber parameters to achieve the desirable dynamic properties.
