Parker负载敏感阀培训L90LS

Arial lift Forest machine
Excavator
Backhoe loader
Hook loader Refuse collector Large wheel loader
n When partial pump flow is used for individual functions
n At high intensity usage
n To create simple system solutions when a number of functions with different flow rates is demanded n When system layout is spread out
n At simultanious operation of functions n Power control and energy conservation
n
Reduce energy losses at idling and transportation
Suitable when;
System with variable pump and LS
Save energy, design advises
n Avoid to mix light and heavy loads from the same pump.
n Avoid to mix large and small flow demands from the same fixed pump.
n Never control max flow with line mounted restrictors.
n Always use the pump regulator to set maximum work pressure when you are using a variable pump. The pressure limiter of the valve needs to be set at least 30 bars above.
n Avoid to limit valve work port pressure with the chock valves, use the build in individual work port feed reducer.
n Make sure that the cylinders are correctly connected to the
valve, the valve is normally adapted to the cylinder ratio.
