Accumulator circiuts
Accumulator circiuts
En ackumulatorkrets hjälper systemet att hålla ackumulatorn laddad till önskat tryckspann, den fungerar liknande en termostat och håller trycket i ackumulatorn inom en ställbar min- och maxnivå.
Hur fungerar dessa ackumulatorkretsar för att avlasta pumpen
Här används en ackumulatorventil tillsammans med en fjärrstyrd tryckbegränsare för att avlasta pumpen. Ett annat exempel är att kombinera den med en prioritetsventil för att omdirigera flödet till annan funktion.
Denna lösning skapar energisnåla och effektiva system, och de passar exempelvis i batteridrivna hydraulsystem.
Dränera manuellt eller elektriskt
Det finns också block med manuell eller elektrisk dränering av ackumulatorn för att inte riskera att man har instängt tryck i systemet efter avstängning.
CE-märkning och plombering
Vid behov finns CE-märkt plomberad tryckbegränsningsventil enligt Arbetsmiljöverkets tryckbärande anordningar AFS 2016:1.
