According to the South Korean Army swiss replica watches Joint Staff Headquarters news, North Korea on the replica watches uk 16th in the south side of the new road in the south of the mirror test a missile, but the test failed, Han Jun Founder is further analysis of rolex replica missile models and other information. Cheong Wa Dae National Security Officer Jinkuan town will convene an emergency meeting in the morning to discuss the current security situation.

TEXT LAYOUT

1. PULSATION_DAMPING
SELECT_SMOOTH goto 2. to find the size you need
PULSE_DAMPER_TYPES goto A. to find the type you need
SELECT_PUMP_APLICAT goto B. to find your pump characteristics
--------------------------------

2. RESIDUAL FLUCTUATION ALLOWED depends on your system, don't over specify.

goto FLOW_FLUCTUATION_OR_PRESSURE_PULSATION
goto 3. FIND_PUMP_F
goto 4. CALC_DAMPER_VOLUME
goto 5. SELECT_PIPE_METHOD
Start damper type selection goto A.
----------------------------------------------------------------------------

A. FLOW THROUGH PRESSURE PULSATION INTERCEPTORS & FLOW FLUCTUATION SMOOTHERS
-------------------------------

6. FLEXFLON_PTFE_DIAPHRAGM pulse damping with Virgin PTFE or MTFE
goto HP_WITH_HAZARD_ALERT "FLO" 2 layer diaphragm & 2ndry containment FLEXORBER HP

-OR- goto LOW_PRESSURE "SOG" 4x life at 50% cost, 8 fold better FLEXORBER LP
--------------------------------
7. BAG_BLADR_TUBE elastomer part dampers EP, Buna N, Fluoro
goto LIQUID_IN_BLADR "HUG" Liquid in the bladder N2 in the shell PIPEHUGGER

-OR- goto GAS_IN_BAG "PIG" N2 in the balloon liquid contacts shell PIPEGUARD

-OR- goto FLEX_TUBE "PUG" for slurries and above 2" suction sys. PUMPGUARD
--------------------------------
8. NO_MOVING_PARTS "Solid State" pressure pulsation dampers

gofor WAG_CER WAG
ceramic balls disperse the pressure transients WAVEGUARD CERAMIC


gofor WAG_HO WAG
multi orifice and multi chamber + delt P & liquid compressibility WAVEGUARD HELMHOLTZ


gofor CAG CAVGD
vertical column to provide head, with bubble collector tube CAVGUARD

----------------------------------------------------------------------------

B. A DOZEN DIFFERENT PUMP SYSTEMS, different volumetric and frequency needs
--------------------------------
goto Hz.
calculate the base cyclic forcing frequency


goto FLOW
calculate the flow fluctuation volume


goto Hz_Vol
determine whether Damper will be Solid State or Volumetric
-----------------------------------------

THEN GO BELOW FOR EXAMPLES AND TYPICAL INSTALLATIONS,
OR GO back TO "A"
-----------------------------------------
goto SUCTION_SYS for suction systems
Preventing cavitation and acceleration head loss, suction pulses


goto PRESUR_PULSE for discharge systems
Intercepting pressure pulsation waves (traveling at 3000 mph)


goto CENTRIFUGAL for resonance & shaft shake
Start up surge, shutdown back flow shock & hammer, resonant pulsation


goto VANE_GEAR_LOBE smooth flow but high Hz.
Small displacement per vane, tooth, lobe, but high frequency pulsation


goto MULTIPLEX_A614 Triplex, quintuplex, septuplex reciprocating pump acoustic pulsation

goto
PACKD_PLUNGR accurate metering
The highest efficiency pumps least lost volume easiest to dampen


goto
AODD_&_VLP LP flow fluctuation smoothing
The volume of the pulse with an AODD depends on how quickly the
return stroke begins, critical need is a large air supply


goto HOSE_PUMPS low pressure and large pipe
For sludge and slurry, catch the pulse spike from shoe hitting tube
on discharge back fill the void from shoe or roller lift off.


goto LP_DOSING_PTFE lost motion flow control
Solenoid, cam, back stroke volume limiting, the flow begins
with a squirt and the highest pressure pulse in the cycle

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.
