KnightHawk Engineering specializes in providing Field Services for support of your engineering efforts as well as ours. KHE has high speed data collection equipment for process and structural dynamic analysis as well as 8 channel analyzer capabilities for detection of harmonics and acoustics. KHE offers battery powered and solar powered capabilities for remote and mobile applications.
KHE's Field Service Personnel have extensive experience in data collection and troubleshooting equipment problems. They are accustomed to working with plant personnel and work very hard at minimizing interference with plant operations. They are capable of working alone with little supervision or working as an extension of your team. Their specialty areas include but are not limited to analysis of Vibration (structural and rotating), Process, Controls and Instrumentation issues. KHE has assembled an extensive set of data acquisition equipment that compliments the skills of our field service personnel.
KHEs Cognitive Vision CV 395; 8 Channel Data Analyzer provides us the ability to diagnose bearing, balance, electrical, alignment, coupling, critical speeds, gear mesh, vane and blade passing problems as well as any others that you may have with your rotating equipment. We have also analyzed structural vibration induced by interference, wind, machinery and process conditions.
KHE has analyzed many process conditions that have resulted in equipment failures, poor quality product or inefficient operations. KHE has worked with operators and users to stream line and scale up their existing processes as well as develop new processes for improved productivity.
It is common to see improperly tuned or malfunctioning control systems as the cause of equipment or process problems. KHE has identified many problems related to controls issues and specializes in working with the client to develop cost effective solutions. Often the solution is negligible, once the problem is correctly identified.
Reciprocating compressors were operating on parallel headers. The vibration on the discharge header was causing support system failures. Dynamic pressure pulsation measurements were taken of the suction and discharge piping systems and structural resonant frequency measurements were made on the piping structure. It was found that the pressure pulsations were being amplified acoustically and were causing the support system failures. Piping system changes were designed that eliminated the acoustic amplification.
The floor of an office building was shaking noticeably when rail cars were moved passed it. The client wanted to know if this was causing damage to the building or if the condition was unsafe. Accelerometers were placed on the under structure of the second floor and readings were taken when various rail cars were moved past the building, both loaded and unloaded. The data was used to determine the displacement and acceleration of the structural components of the building. In addition vibration frequencies were compared to the natural resonant frequencies of the structure. It was determined that the structure was safe and not being damaged. To reduce the vibration experienced by the personnel in the building it was suggested that an isolation barrier be placed in the ground between the rail tracks and the building
A gear pump was not operating on design when above 75% speed. Flow and Pressure measurements were taken at the suction and discharge of the pump under various operating conditions. As the pump increased in speed, pressure pulsation characteristics changed from spikes to spikes with a ring out effect. It was determined that at higher flow rates gas was being trapped in the polymer and not allowed to disperse prior to reaching the pump. This was causing a partial displacement of product in each fill cycle. The condition worsened as the speed increased. The upstream piping system was redesigned to allow the gas to disperse more quickly at higher flow rates
