1. Motor<\/a> rychlost kles\u00e1.<\/strong><\/p>\n

Nejprve je t\u0159eba otestovat v\u00fdkon samotn\u00e9ho motoru. Pokud je v\u00fdstupn\u00ed v\u00fdkon motoru ni\u017e\u0161\u00ed ne\u017e jmenovit\u00fd v\u00fdkon, m\u016f\u017ee b\u00fdt p\u0159\u00ed\u010dinou poruchy \u0161patn\u00e1 kvalita paliva, n\u00edzk\u00fd tlak paliva, \u0161patn\u00e1 v\u016fle ventil\u016f, nefunk\u010dn\u00ed v\u00e1lec motoru, \u0161patn\u00e9 \u010dasov\u00e1n\u00ed vst\u0159ikov\u00e1n\u00ed, \u0161patn\u00e9 nastaven\u00ed mno\u017estv\u00ed paliva, \u00fanik vzduchu v sac\u00edm syst\u00e9mu, vadn\u00e1 brzda a jej\u00ed ovl\u00e1dac\u00ed p\u00e1ka a nahromad\u011bn\u00ed karbonu turbodmychadla. Pokud sel\u017ee \u0159\u00eddic\u00ed syst\u00e9m \u010derpadla, nelze realizovat optimalizaci zat\u00ed\u017een\u00ed a slad\u011bn\u00ed stavu motoru, \u010derpadla a ventilu v r\u016fzn\u00fdch pracovn\u00edch podm\u00ednk\u00e1ch a rypadlo nebude pracovat norm\u00e1ln\u011b. Tento druh z\u00e1vady by m\u011bl za\u010d\u00edt od elektrick\u00e9ho syst\u00e9mu a pot\u00e9 zkontrolovat hydraulick\u00fd syst\u00e9m. Nakonec zkontrolujte mechanick\u00fd p\u0159evodov\u00fd syst\u00e9m.<\/p>\n

2. Pracovn\u00ed rychlost se zpomal\u00ed. <\/strong><\/p>\n

Hlavn\u00edm d\u016fvodem n\u00edzk\u00e9 pracovn\u00ed rychlosti rypadla je pokles v\u00fdkonu motoru a net\u011bsnost hydraulick\u00e9ho syst\u00e9mu zp\u016fsoben\u00e1 opot\u0159eben\u00edm v\u0161ech \u010d\u00e1st\u00ed cel\u00e9ho stroje. Hydraulick\u00e9 \u010derpadlo rypadla je \u010derpadlo s prom\u011bnn\u00fdm plun\u017erem. Po ur\u010dit\u00e9 dob\u011b pr\u00e1ce dojde nevyhnuteln\u011b k nadm\u011brn\u00e9mu opot\u0159eben\u00ed vnit\u0159n\u00edch hydraulick\u00fdch sou\u010d\u00e1st\u00ed \u010derpadla (blok v\u00e1lce, p\u00edst, ventilov\u00e1 deska, deska s dev\u00edti otvory, \u017eelv\u00ed h\u0159bet atd.), co\u017e zp\u016fsob\u00ed vnit\u0159n\u00ed net\u011bsnost a parametry nejsou koordinov\u00e1ny, co\u017e m\u00e1 za n\u00e1sledek nedostate\u010dn\u00fd pr\u016ftok, vysokou teplotu oleje a pomalou pracovn\u00ed rychlost. V t\u00e9to dob\u011b je nutn\u00e9 prov\u00e9st gener\u00e1ln\u00ed opravu cel\u00e9ho stroje, opravit a vym\u011bnit d\u00edly, kter\u00e9 p\u0159ekra\u010duj\u00ed hranici opot\u0159eben\u00ed.<\/p>\n

3. Rypadla<\/a> jsou slab\u00e9.<\/strong><\/p>\n

Slab\u00e9 hlouben\u00ed je jednou z typick\u00fdch z\u00e1vad r\u00fdpadel. Existuj\u00ed dv\u011b situace pro slab\u00e9 hlouben\u00ed: jednou je slab\u00e9 hlouben\u00ed, motor neudr\u017e\u00ed v\u016fz a n\u00e1klad je velmi lehk\u00fd; druhou je slab\u00e9 hlouben\u00ed, kdy\u017e v\u00fdlo\u017en\u00edk nebo ty\u010d l\u017e\u00edce dos\u00e1hne konce, motor v\u00e1\u017en\u011b dr\u017e\u00ed v\u016fz, nebo se dokonce zastav\u00ed\u3002.<\/p>\n
