               SCHEME HORISONTAL HIDRAULYC PRESS COMENTED


     CONDITION   Condition rapid advance ram to clos and then slowly advance and retread fost clip.
                              Using tow pumps with a high flow.and low pressure,and one high pressure and low flow,
hand distributor,a flow valve and pressure (safety valve)
     OPERATION    Driven pumps are started by the same engine drawer manually is fixed on pozision parallel

arrows.It should be noted that the facility have a safety valve (pressure limit) P2 and a flow valva (download)P1
external pilot pressure mainstaking  P2>P1
      Passing above the distributor position,the fluid goes directly into the piston head quickly pushing the pluger(ram)  It will  go in front until the ram will  oppose a force(material release)on the main circuit  of the
plant creating a high presure P2 will open through the pilot valve P1 and all fluid discharge from the pump BP
going to tank.
      HP  pump will continuie to maintain the ram pressure (pressing force) that tightening is done at slow speed
pump flow is small.For HP pump pressure not to go in BP pump circuit built between the tow pump a check valve  S1 which is based on doing the exercise condition that the instalation work is P2>P1 Manual pressing
finish the distributor passes the cilindrer rod position crossed arows will with  draw  quickly and  ram head race by electrical contact,distributor wilpass in the neutral position that is still fluid in the sistem will go to the tanc  and
the cicle repeat.
