Instead, a packager purchases the compressor, the driver and other high-value content from individual manufacturers, and then integrates and assembles them on a fabricated I-beam skid with pulsation bottles, scrubbers, gas piping, utility piping, instrumentation, controls and auxiliaries.
Furthermore, the changes of the mean density of the gaining star as a result of accretion of matter can affect the pulsation periods and pulsation properties of oEA stars.
A theoretical analysis based on the method of balance of energies was employed to discuss temperature pulsations of the plant leaf during the sunny period of the day.
The hydraulic accumulator is one of the hydraulic elements of the system that will be used to reduce pressure and speed pulsation inside it; thus, the selection and workflow modelling have a significant influence on the stability of the entire system.
The new motor servo control and a 2 microsecond machining loop time allow faster retraction during pulsations.
The effects of pulsations and pressure surges in pumping systems can range from minor shakes and rattles - inconvenient but of no great significance - to permanent and expensive damage to instrumentation and fittings subjected to transient pressure peaks, inaccurate flow meter and pressure gauge readings, blown gaskets, weeping relief valves, fractured pipework and leakage.
The "allover" patterning of the Hong Kong stock exchange workers' red, white, and black uniforms doesn't suggest Jackson Pollock, but does bring to mind the ordered optical pulsations that neo-Impressionist painters strived for: in this case, not so much Seurat as his epigone Signac, or even the early Matisse when he labored under Signac's tutelage.
Smooth Startup and Operation--Like all of ERI's PX devices, the PX-300 operates without the pulsations and water hammer caused by competing isobaric energy recovery devices.
The nozzle resonant pulsations were causing high vibrations and were the primary cause of concern, although the high frequency responses above 200 Hz were likely complicating the valve motion and may have been coincident with valve mechanical responses, which limited valve life.
But, there are significant common factors that affect the entire system performance - such as fuel flow, thermal distribution, fuel distribution, NVH and hydraulic pulsations.
The workshops are held every 10 years, and this latest addressed such unanswered questions as the chemical evolution of the different spectral types of white dwarfs, and the excitation of pulsations.
To convert those pulsations into directional motion, the animals typically exploit transient changes in the friction between their bodies and the underlying surface, restricting propulsion to one direction, says applied mathematician Lakshminarayanan Mahadevan of Harvard University.
