Inline Pulse-Tone Hydraulic Shock SuppressorsCatalog HY10-1630/USPageIntroductionWhy Should You Use theShock Suppressor?Noise pollution is the hottest topic in the hydraulicindustry today. Lab tests show that pump noise levelsare increased by 2-3 dB(A) just by adding 12 feet ofoutlet and return lines. The lines do not generatenoise. They radiate noise when they respond topulsations or vibrations. The pulsations are usuallygenerated by the pump, and the vibrations are radiated by large flat machine surfaces.It is almost impossible to forecast how much additional sound the hydraulic lines and surroundingstructure will radiate. This is why many power unitsare enclosed after they have been manufactured andinstalled.The Inline Pulse-Tone reduces pump pulsations andshock. When you stop pulsation and vibration, youstop the cause of component wear and leakage. Apower unit with an Inline Pulse-Tone installed canoperate at higher RPM with smaller, less expensivecomponents . . . and less noise.Not only do hydraulic lines radiate noise, but theyfrequently provide the primary path for propagatingnoise from the pump to components that, in turn,react to the noise and radiate additional sound. Thishelps explain why many pump manufacturers have avery low dB(A) pump rating, but when the pump isinstalled on a power unit, the sound rating is muchhigher.How Does theNOTE OF INTEREST: An increase of 2.71 dBdoubles the intensity noise level.Work?An Inline Pulse-Tone suppressor is located as close tothe pump as possible, usually directly at the pumpoutlet, to stop pulsations and noise before they travelthrough the piping and radiate off other structuralcomponents.As shown in the diagram on the facing page, oilflowing into the Pulse-Tone goes through threedifferent baffles or diffusers. These metal bafflesare designed to convert 1/2” diameter holes to 1/32”diameter holes. The total radial distance throughthese baffles is only 1/4”.After passing through these holes, pulsations strike anitrogen charged rubber bladder. The bladder deflectseach time it is hit by a pulsation. This slight deflectionof the bladder reduces the shock and noise.The bladder is usually charged with nitrogen to 50%to 60% of the hydraulic operating pressure. The 1/32”diameter holes in the last baffle are so small that thebladder cannot extrude into them.The large area of the bladder, its ability to oscillate ata high frequency and the short distance each pulsation has to travel once it enters the unit explain theeffectiveness of the Pulse-Tone.Selecting ais Easy!No complex sizing forumla is required. The InlinePulse-Tone hydraulic shock suppressor is sized tomatch your hydraulic line size. There is a unit to fitevery pipe and tube size from 3/8” to 2” with threadedor flanged connections. Models are available for both3000 PSI and 5000 PSI hydraulic system pressures.89Parker Hannifin CorporationHydraulic Accumulator DivisionRockford, Illinois USA

Pulse-Tones3000 PSICatalog HY10-1630/USSpecifications and DimensionsThere have been many attempts to solve the problemscaused by high transient flow conditions inherent withpulsations and shocks. All attempts have had one thing incommon: they never quite solved the problem. Then cameGreer’s Pulse-Tone concept, a patented breakthrough inpulsation control. The trouble with the previous devices wasthat most of the pulsations and shocks never got near theshock absorber. Pulse-Tone puts a flow diversion baffle intothe line. Fluid traveling through the hydraulic line bendsaround the baffle, but pulsation and shock energy waves takethe path of least resistance right into the nitrogen prechargedbladder. The bladder absorbs up to 98% of the waves’potentially destructive force.EAWhy Use Pulse-Tones?
