Pulsation and Vibration Analysis

string of various pulsations created which LDi analyzes and prevents

ShockView enables us to quickly and accurately run your proposed piping system, in our computers, and tell you what the maximum level of pump start up surge, or shutdown shock will be. From this first model, which is free to you, we can then determine which of our alleviators is most suited to the needs of your system.
If you wish further models of your system, please contact Dave Charles of Liquid Dynamics International in Europe with at least the following information:

Pipe Parameters:
"L" Length, "Di" Internal Diameter, "t" Wall thickness, "bM" Material, (modulus if known)
Liquid specifics:
Flow rate "Q" Kg/Sec. if known, SG, cP viscosity at temp.
Pump manufacturer inertia data:
"S" Seconds Spin-up time (the most important figure.)

PulseDoctor and ShockDoctor DIAGNOSTICS
You have the hardware already? LDi has the tools Certified calibrated signal conditioned transducers. Real time massive paper rate, oscillograph printers. GPIB data stream capture laptops, with FFT analysis. Yes even stethoscopes! Let us identify the heart of the problem, on site.
PulseDoctor and ShockDoctor diagnostics - study your system
You have the dimensions, we will generate pipe response characteristics.
Identify and predict the results of valve action.
Find the pipe shake from pump start-up surge. Enable you to design "Water Hammer" out of your system.
ShockView analysis - check system and prevent problems
Before you invest in system hardware, LDi will run it for you. A "no witchcraft" easy to read set of oscillographic printouts, show you any system dangers, from frequency and amplitude. Allows you to choose the right pump speed and pipe lengths, before your budget is spent.
PulseView software models - LDi run thorugh of your system,

Selecting Pulsation Dampeners for Different Pump Systems.
Flow through pulsation dampers are at least 3 times more efficient than T off line accumulators.
Dampeners that do, flow goes through, but pressure pulsation does not.
