Reinig de aansluitingen, controleer de massa van het chassis en controleer het hoofdrelais\/contacten.<\/li>\n<li><strong>Vloeistofpeil en toestand<\/strong>Controleer het peil in het reservoir en gebruik de voorgeschreven vloeistof. Een laag peil of vervuilde olie veroorzaakt cavitatie, lawaai en verlies van hefvermogen. Vervang verstopte filters en ontluchtingsdoppen indien nodig.<\/li>\n<li><strong>Soleno\u00efden en bedrading<\/strong>Controleer de uitgang van de regelaar naar de spoelen \u201comhoog\u201d en \u201comlaag\u201d. Luister of de spoel klikt en controleer het magnetisme met een gereedschap. Een snelle veldoplossing is het verwisselen van spoelen omhoog\/omlaag om een vastgelopen bed te laten zakken en vervolgens de defecte spoel te vervangen.<\/li>\n<li><strong>Ontlastkleppen en keerkleppen<\/strong>Als de motor loopt maar de druk laag is, controleer dan de overdrukinstelling en de keerkleppen op vuil. Een vastzittende of te laag ingestelde ontlastklep veroorzaakt geen of weinig hefvermogen.<\/li>\n<li><strong>Cilinders en lekken<\/strong>Aanhoudende drift of langzame terugkeer wijst naar interne <a href=\"\/hydraulic-cylinders\/\">cilinder<\/a> bypass of externe lekken.

Controleer dit altijd aan de hand van de documentatie van je voertuig.<\/p>\n<h4>Wat als het apparaat lekt via de ontluchting?<\/h4>\n<p>Een bijna lege accu en een zware bak kunnen drukpieken veroorzaken tijdens het dalen, waardoor olie uit een vervuild ontluchtingsfilter wordt geperst. Laad de accu op en reinig\/vervang het ontluchtingsfilter.<\/p>\n<h4>Waarom hoor ik geklik maar geen beweging?<\/h4>\n<p>De elektromagneet kan bekrachtigd zijn maar de motor heeft een lage spanning of de klepspoel schakelt niet. Test de accu, controleer de massa en test het magnetisme van de spoel.<\/p>\n<h4>Kan ik een vast bed tijdelijk laten zakken?<\/h4>\n<p>Ja. Verwissel de omhoog\/omlaag spoelen op het spruitstuk om het bed te verplaatsen en herstel en vervang vervolgens de defecte spoel.<\/p>\n<h4>Wanneer bel ik een professional?<\/h4>\n<p>Als de lekken aanhouden na het vervangen van de afdichting, als de pomp geen druk opbouwt ondanks elektrische controles, of als u niet over het gereedschap beschikt om veilig af te tappen, te demonteren en te testen.<\/p>","protected":false},"excerpt":{"rendered":"<p>What is a Dump Trailer Hydraulic Pump?
