Steve Zarembski, vice president of planning and marketing for Haldex Barnes, said the WQ pump is designed to dramatically reduce system pressure pulsation
, which then reduces fluidborne noise and leads to a quieter hydraulic system.
generator is capable of varying both the frequency of pulsations
and the amplitude.
When installing pulsation
dampeners and back pressure valves in any pumping system, location and proximity are key.
The operation of the pulsation
system is to ensure that the pulse generator remotely generates pneumatic pulses of a certain power in the pulsation
chamber through a pulse conductor and leads to the oscillation of the suspension .
Research of a level of pressure fluctuations reducing in the normal pump operation mode has shown that the regular damper reduces the pressure pulsation
Before optimization, the compression chamber is overcompressed, with a pulsation
peak of about 0.
Higher speed compressors naturally create a broader spectrum of gas pulsation
frequencies that must be addressed in the system design.
The wide range applications of the PMBLDC motor drives from ranging ships propulsion to robotics is another motivation of many researchers to investigate new methodologies for reducing the torque pulsation
and speed ripple.

Too much pulsation
in the flow stream will show up as apparent vibration, or bouncing, of the rotameter's float, and this is an indication that the observed flow cannot be relied on as accurate.
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.
Optional features include a pulsation
damper, back-flushing system, barrier chamber system, diaphragm monitor, stroke counting and extended special ports for use in sanitary conditions.
