      A properly installed and maintained pump set can deliver years of reliable service. Follow these tips to protect your investment:<\/span><\/p>\n

        \n
      • \n

        Wymieniaj filtry hydrauliczne zgodnie z harmonogramem<\/span><\/strong>\u00a0\u2013 Zanieczyszczony olej jest najwi\u0119kszym wrogiem pomp hydraulicznych. U\u017cywaj oryginalnych lub wysokiej jako\u015bci filtr\u00f3w i wymieniaj je w odst\u0119pach zalecanych przez Hitachi (zazwyczaj 500\u20131 000 godzin). Zatkany lub omijaj\u0105cy filtr pozwala zanieczyszczeniom na zarysowanie bloku cylindrowego i p\u0142yty zaworowej.<\/span><\/p>\n<\/li>\n

      • \n

        Utrzymuj olej w czysto\u015bci i o odpowiedniej lepko\u015bci<\/span><\/strong>\u00a0\u2013 U\u017cywaj ISO VG 46 dla normalnych temperatur, ISO VG 68 dla gor\u0105cego klimatu lub ci\u0105g\u0142ej ci\u0119\u017ckiej pracy. Zanieczyszczenie wod\u0105 degraduje olej i powoduje wewn\u0119trzn\u0105 korozj\u0119. Zlecaj analiz\u0119 oleju raz w roku.<\/span><\/p>\n<\/li>\n

      • \n

        Rozgrzej pomp\u0119 przed ci\u0119\u017ck\u0105 prac\u0105<\/span><\/strong>\u00a0\u2013 Uruchom silnik na niskich obrotach biegu ja\u0142owego na 3\u20135 minut, a nast\u0119pnie powoli cykluj wszystkie funkcje hydrauliczne bez obci\u0105\u017cenia. Pozwala to olejowi dotrze\u0107 do wszystkich wewn\u0119trznych element\u00f3w i zapobiega uszkodzeniom kawitacyjnym.<\/span><\/p>\n<\/li>\n

      • \n

        Monitoruj przep\u0142yw sp\u0142ywu z obudowy<\/span><\/strong>\u00a0\u2013 Excessive case drain leakage (more than 15\u201320 L\/min per pump) indicates internal wear. Measure it every 1,000 hours. A sudden increase signals impending failure.<\/span><\/p>\n<\/li>\n

      • \n

        Nas\u0142uchiwanie nietypowych d\u017awi\u0119k\u00f3w<\/span><\/strong>\u00a0\u2013 Stukanie, wycie lub piszczenie z okolicy pompy cz\u0119sto wskazuje na kawitacj\u0119 (g\u0142odzenie ssania), zu\u017cyte \u0142o\u017cyska lub lu\u017any monta\u017c. Natychmiast zbadaj przyczyn\u0119 \u2013 kontynuacja pracy spowoduje katastrofaln\u0105 awari\u0119.<\/span><\/p>\n<\/li>\n

      • \n

        Sprawd\u017a wyr\u00f3wnanie pompy<\/span><\/strong>\u00a0\u2013 Nieprawid\u0142owe ustawienie pompy wzgl\u0119dem obudowy ko\u0142a zamachowego silnika powoduje obci\u0105\u017cenie boczne wa\u0142u, niszcz\u0105c \u0142o\u017cyska i uszczelnienie wa\u0142u. Po ka\u017cdym demonta\u017cu silnika lub pompy sprawd\u017a wyr\u00f3wnanie za pomoc\u0105 czujnika zegarowego.<\/span><\/p>\n<\/li>\n

      • \n

        Utrzymuj przew\u00f3d sp\u0142ywu z obudowy dro\u017cny<\/span><\/strong>\u00a0\u2013 Zgi\u0119ty lub zablokowany przew\u00f3d sp\u0142ywu z obudowy spowoduje ci\u015bnienie wsteczne wewn\u0105trz obudowy pompy, wysadzaj\u0105c uszczelnienie wa\u0142u. Sprawdzaj przew\u00f3d przy ka\u017cdym serwisowaniu pompy.<\/span><\/p>\n<\/li>\n

      • \n

        Prawid\u0142owo przechowuj zapasowe pompy<\/span><\/strong>\u00a0\u2013 Przechowuj odbudowane pompy w oryginalnej drewnianej skrzyni, w suchym, czystym \u015brodowisku. R\u0119cznie obracaj wa\u0142em co 6 miesi\u0119cy, aby rozprowadzi\u0107 wewn\u0119trzny smar.<\/span><\/p>\n<\/li>\n

      • \n

        U\u017cywaj nowych O-ring\u00f3w i podk\u0142adek uszczelniaj\u0105cych<\/span><\/strong>\u00a0\u2013 Podczas instalacji odbudowanej pompy zawsze wymieniaj wszystkie uszczelnienia na przy\u0142\u0105czach hydraulicznych. Ponownie u\u017cyte uszczelnienia s\u0105 najcz\u0119stszym \u017ar\u00f3d\u0142em zewn\u0119trznych wyciek\u00f3w.<\/span><\/p>\n<\/li>\n

      • \n

        Odpowietrz uk\u0142ad po instalacji<\/span><\/strong>\u00a0\u2013 After fitting the pump set, run the engine at low idle and slowly cycle each function several times to purge trapped air. Air in the system causes cavitation and noisy operation.<\/span><\/p>\n<\/li>\n

      • \n

        Prowad\u017a dziennik serwisowy<\/span><\/strong>\u00a0\u2013 Rejestruj dat\u0119 instalacji, godziny pracy, wymiany oleju i wszelkie nietypowe obserwacje. Pomaga to przewidzie\u0107 \u017cywotno\u015b\u0107 pompy i unikn\u0105\u0107 nieplanowanych przestoj\u00f3w.<\/span><\/p>\n<\/li>\n<\/ul>\n

        \n

        Critical installation tip for the 9147340 \/ 9149225 remanufactured pump set:<\/span><\/strong>
        \n\u2013 Uszczelnienia p\u0142ywaj\u0105ce\u00a0<\/span>przew\u00f3d sp\u0142ywu obudowy<\/span><\/strong>\u00a0on each pump must be clear and unrestricted. A blocked case drain will blow the shaft seal instantly on first startup.<\/span>
        \n\u2013 Before installing the remanufactured pumps, flush the entire hydraulic system and replace all filters. Contaminants from the failed pumps will destroy a remanufactured unit just as quickly as a new one.<\/span>
        \n\u2013 U\u017cywaj nowych O-ring\u00f3w i podk\u0142adek uszczelniaj\u0105cych przy ka\u017cdym po\u0142\u0105czeniu hydraulicznym. Ponowne u\u017cycie uszczelek gwarantuje wycieki.<\/span>
        \n\u2013 After installation, run the engine at low idle for 2\u20133 minutes with the pumps in neutral, then slowly cycle each function (boom, arm, bucket, swing, travel) to purge air from the system.<\/span>
        \n\u2013 Check pump alignment with the engine flywheel housing \u2013 misalignment causes premature bearing failure and shaft seal leakage.<\/span><\/p>\n<\/blockquote>\n

        \n
