  1. Fluid Mechanics LAB:Hydraulics Circuits ENTC - 303 PROF. ALVARADO

  2. Regeneration Circuit Retraction Stroke QT=QP Vp_Ret=QP/(Ap-Ar) Where: QT= Total flow rate QP= Pump flow rate Vp_Re= Velocity of Piston (retraction) Ap= Area Piston Ar= Area Rod PROF. ALVARADO

  3. Regeneration Circuit QT= QP + QR QP=QT - QR QP=APVP_ext - (AP-Ar)VP_ext Vp_ext=QP/Ar Where: QT= Total flow rate QP= Pump flow rate QR=Regenerative Flow rate Vp_ext= Velocity of Piston (extension) Ap= Area Piston Ar= Area Rod Extension Stroke

  4. Synchronization Circuits Series Cylinders Condition: AP_2=AP_1 - AR_1 Governing Equations: P1AP1 – P2 (AP1- AR1) = F1 P2AP2 – P3 (AP2- AR2) = F2

  5. Synchronization Circuits Parallel Cylinders In order to achieve synchronization of the two cylinders, it is necessary that loads and Cylinders are equal. PROF. ALVARADO
