Pulse Doctor ToolsLiquid Dynamics - Pulse Doctor Services
Example: Suction pressure too high. Driving the pump, instead of it "doing its thing".

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.


Long Pipes
Pipeline Shock and Pulsation Analysis
"Joukowsky" velocity jump, excites RV.
Analysis
For more on the example please see LDi Pub.1 P.7
Gauge Graph
The answer is simple, as usual it’s the pipe,
it is stopping one cylinder filling – too long..


Pipe-Doctor PicturePipe-Doctor
For more on the "manifolding" examples, please see Octopussies LDi Pub. 5. P34, 35.
Survey

We will survey your pumping system pipe and advise where:
1. They are oversized
2. Direction changes are causing instability
3. "T’s" & "Hard 90’s" need replacing
NO = RPM doubled from 1950’s design, valves driven off seats by suction column oscillation
YES = Stop valves from "talking" to each other.
NO WAY = Typical manifold, turns pulse into an "orchestra"
YOU BET = intercepts
