Skupna neuspe\u0161nost Hidravli\u010dna \u010drpalka za bagre<\/a><\/strong><\/p>\n

1. Motor<\/a> hitrost se zmanj\u0161a.<\/strong><\/p>\n

Najprej je treba preveriti izhodno mo\u010d samega motorja. \u010ce je izhodna mo\u010d motorja manj\u0161a od nazivne mo\u010di, so lahko vzrok okvare slaba kakovost goriva, nizek tlak goriva, napa\u010dna zra\u010dnost ventilov, valj motorja ne deluje, napa\u010den \u010das vbrizga, napa\u010dna nastavitev koli\u010dine goriva, uhajanje zraka v sesalnem sistemu, okvara zavore in njene krmilne ro\u010dice ter kopi\u010denje ogljika v turbopolnilniku. \u010ce sistem za nadzor \u010drpalke odpove, ni mogo\u010de izvesti optimizacije obremenitve in usklajevanja stanja motorja, \u010drpalke in ventila v razli\u010dnih delovnih razmerah in bager ne bo deloval normalno. Tovrstne napake je treba za\u010deti pri elektri\u010dnem sistemu, nato pa preveriti hidravli\u010dni sistem. Na koncu preverite mehanski prenosni sistem.<\/p>\n

\"\"<\/p>\n

2. Hitrost dela se upo\u010dasni. <\/strong><\/p>\n

Glavni razlog za nizko delovno hitrost bagra je zmanj\u0161anje mo\u010di motorja in pu\u0161\u010danje hidravli\u010dnega sistema zaradi obrabe vseh delov celotnega stroja. Hidravli\u010dna \u010drpalka bagra je \u010drpalka s spremenljivim potisnim mehanizmom. Po dolo\u010denem \u010dasu delovanja bodo notranji hidravli\u010dni sestavni deli \u010drpalke (blok cilindra, bat, ventilna plo\u0161\u010da, plo\u0161\u010da z devetimi luknjami, \u017eelvji hrbet itd.) neizogibno povzro\u010dili prekomerno obrabo, kar bo povzro\u010dilo notranje pu\u0161\u010danje, parametri pa niso usklajeni, zaradi \u010desar je pretok nezadosten, temperatura olja visoka in delovna hitrost po\u010dasna. V tem \u010dasu je treba opraviti generalni pregled celotnega stroja, popraviti in zamenjati dele, ki presegajo mejo obrabe.<\/p>\n

3. Bagerji<\/a> so \u0161ibki.<\/strong><\/p>\n

\u0160ibko odkopavanje je ena od zna\u010dilnih napak bagra. Obstajata dva primera \u0161ibkega odkopavanja: prvi je \u0161ibko odkopavanje, motor ne dr\u017ei avtomobila in obremenitev je zelo majhna; drugi je \u0161ibko odkopavanje, ko droga droga vitla ali vedra dose\u017ee konec, motor resno dr\u017ei avtomobil ali se celo ustavi\u3002<\/p>\n
