NXQ  hydraulic accumulator

	The accumulator can be accumul  ated the energy replenished leakage provided constant pressure sucked in pulse pressure etc It can be used for auxiliary energy power and urgent energy power Series NXQ rubber bag accumulator is adopted rotary-press forming with seamless pipe technique It features compact structure beautiful look light weight small inertia and steady function The design is conformed to JB/T7036-93 "Technieal condition for hyd-accumulator" It is used oil-base hydraulic oil medium in system The bag of cooler is charged with nitrogen for normal working ranged into -10~+70 Easy operation large series production capacities welcome to orders

	Application and feature
	Application Feature  Sucked shock of hydraulic Accumulator is normal mounted before the directional valve or the eylinder It can suck or slow sudden exchanging clirection or suddden stopping of the cylinder for shock perssure  For hydraulic air spring  Spring rate KT is equal equivalent cylinder action force causing by gas bag pressing for differential pressure divided equivalent cylinder of position movingmean KT=(P2-P1)A/(V1-V2)A(Pa.m) In formula P1P2-min operating pressure and max. operating pressure Pa A effective area of equivalent cylinder m2 V1.V2-volume of gas for pressure P1and pressure P2 m3 Reducing flowate of pulse and pressure  Piston pump a little gears contacting gear pump relief valve etc in hydraulic system They can cause hydraulic pressure flowrate for pulse Mounting accumulator can be reduce hydraulic pulse and noise For heat expand compensator When the temperture is raising up in sealed hydraulic system The hydraulic oil is produced expand of volume Because fluid expand ratio is general bigger then pipe material expand ratio It will cause oil pressure for raising up The avvumulator can suck up fluid volume of increment protect exceed pressure ensure satety When the temperature is reducing the fluid will contract The accumulator will supply fluid for requiring in system  Improving on frequency property  When hydraulic system is adopted compensative of pre variable mechanism time constant is for bigger the avvumulator can quickly release pressure for improving on frequency property
