data-start=\"442\" data-end=\"562\">In dit praktijkvoorbeeld betreft het een waterhydraulisch systeem waarbij het filterelement buitensporig vervuild bleek.<\/p><p data-start=\"564\" data-end=\"590\">De vervuiling bestond uit:<\/p><ul data-start=\"592\" data-end=\"746\"><li data-start=\"592\" data-end=\"641\"><p data-start=\"594\" data-end=\"641\">Harde korrelstructuren van onbekende herkomst<\/p><\/li><li data-start=\"642\" data-end=\"659\"><p data-start=\"644\" data-end=\"659\">Sludgevorming<\/p><\/li><li data-start=\"660\" data-end=\"685\"><p data-start=\"662\" data-end=\"685\">Bacteri\u00eble vervuiling<\/p><\/li><li data-start=\"686\" data-end=\"746\"><p data-start=\"688\" data-end=\"746\">Restanten ondanks toevoeging van antibacteri\u00eble middelen<\/p><\/li><\/ul><p data-start=\"748\" data-end=\"921\">Sludgevorming en bacteri\u00eble activiteit zijn binnen waterhydrauliek verklaarbaar.<br data-start=\"828\" data-end=\"831\" \/>De aanwezigheid van harde korrels van een mechanisch sterker materiaal is dat echter niet.<\/p><p data-start=\"923\" data-end=\"997\">Volgens de opdrachtgever komen deze elementen \u201caltijd zo uit het systeem\u201d.<\/p><p data-start=\"999\" data-end=\"1119\">Juist dat gegeven vormt technisch gezien een duidelijke aanleiding om de herkomst van deze korrels nader te onderzoeken.<\/p><h3 data-start=\"1126\" data-end=\"1181\">Aangetroffen: meerdere achtergebleven afdichtringen<\/h3><p data-start=\"1183\" data-end=\"1310\">Bij demontage van het filterhuis zijn vier oude afdichtringen aangetroffen die niet waren verwijderd bij eerdere filterwissels.<\/p><p data-start=\"1312\" data-end=\"1354\">Dit heeft potentieel ingrijpende gevolgen:<\/p><ul data-start=\"1356\" data-end=\"1506\"><li data-start=\"1356\" data-end=\"1401\"><p data-start=\"1358\" data-end=\"1401\">Onjuiste afdichting van het filterelement<\/p><\/li><li data-start=\"1402\" data-end=\"1447\"><p data-start=\"1404\" data-end=\"1447\">Interne bypass van ongefilterde vloeistof<\/p><\/li><li data-start=\"1448\" data-end=\"1474\"><p data-start=\"1450\" data-end=\"1474\">Onvoorspelbare drukval<\/p><\/li><li data-start=\"1475\" data-end=\"1506\"><p data-start=\"1477\" data-end=\"1506\">Versnelde vervuilingsopbouw<\/p><\/li><\/ul><p data-start=\"1508\" data-end=\"1703\">Wanneer meerdere ringen zich opstapelen, kan het element niet correct positioneren of afdichten. Het systeem kan daardoor gedeeltelijk ongefilterd functioneren zonder dat dit direct zichtbaar is.<\/p><h3 data-start=\"1710\" data-end=\"1737\">Advies bij filterwissel<\/h3><p data-start=\"1739\" data-end=\"1823\">Om verdere systeemvervuiling te beperken is geadviseerd om bij iedere elementwissel:<\/p><ul data-start=\"1825\" data-end=\"2030\"><li data-start=\"1825\" data-end=\"1864\"><p data-start=\"1827\" data-end=\"1864\">De filterpot volledig leeg te maken<\/p><\/li><li data-start=\"1865\" data-end=\"1919\"><p data-start=\"1867\" data-end=\"1919\">Achtergebleven vervuiling handmatig te verwijderen<\/p><\/li><li data-start=\"1920\" data-end=\"1982\"><p data-start=\"1922\" data-end=\"1982\">Oude afdichtringen actief te controleren en te verwijderen<\/p><\/li><li data-start=\"1983\" data-end=\"2030\"><p data-start=\"1985\" data-end=\"2030\">Nieuwe afdichtingen correct te positioneren<\/p><\/li><\/ul><p data-start=\"2032\" data-end=\"2174\">Het uitsluitend vervangen van het element zonder reiniging van de pot leidt ertoe dat bezonken contaminatie direct opnieuw in circulatie komt.<\/p><p data-start=\"2176\" data-end=\"2305\">Daarnaast is geadviseerd de filterelementen in een kortere onderhoudscyclus te vervangen, gezien de structurele vervuilingsgraad.<\/p><p data-start=\"2312\" data-end=\"2549\">Hoewel de opdrachtgever op dit moment geen aanvullend onderzoek naar de herkomst van de harde korrels wenst uit te voeren, blijft het technisch gezien onwenselijk om dergelijke contaminatie structureel in het systeem te laten circuleren.<\/p><p data-start=\"2551\" data-end=\"2597\">Binnen waterhydrauliek geldt in het bijzonder:<\/p><p data-start=\"2599\" data-end=\"2686\">Wat structureel in het filter achterblijft, heeft eerder door het systeem gecirculeerd.<\/p><h3 data-start=\"262\" data-end=\"316\">Technische verantwoordelijkheid en beheersbaarheid<\/h3><p data-start=\"318\" data-end=\"482\">Wanneer structurele vervuiling, harde contaminatie en onjuiste afdichtingen aantoonbaar aanwezig zijn, verschuift het vraagstuk van onderhoud naar risicobeheersing.<\/p><p data-start=\"484\" data-end=\"581\">Zolang de herkomst van harde deeltjes niet wordt vastgesteld, blijft er onzekerheid bestaan over:<\/p><ul data-start=\"583\" data-end=\"736\"><li data-start=\"583\" data-end=\"622\"><p data-start=\"585\" data-end=\"622\">Materiaalafbraak binnen het systeem<\/p><\/li><li data-start=\"623\" data-end=\"661\"><p data-start=\"625\" data-end=\"661\">Versnelde slijtage van componenten<\/p><\/li><li data-start=\"662\" data-end=\"693\"><p data-start=\"664\" data-end=\"693\">Langetermijnbetrouwbaarheid<\/p><\/li><li data-start=\"694\" data-end=\"736\"><p data-start=\"696\" data-end=\"736\">Verantwoordelijkheid bij vervolgschade<\/p><\/li><\/ul><p data-start=\"738\" data-end=\"838\">Een installatie kan blijven functioneren, maar dat betekent niet dat zij aantoonbaar beheerst wordt.<\/p><p data-start=\"840\" data-end=\"953\">Professionele systeembeheersing vraagt om inzicht in oorzaak en herkomst \u2014 niet alleen vervanging van onderdelen.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section
