jedna. Vizu\u00e1ln\u00ed kontrola: V\u00fdrobce hydraulick\u00fdch v\u00e1lc\u016f z \u010c\u00edny<\/a> Prove\u010fte vizu\u00e1ln\u00ed kontrolu v\u00e1lce, zda nevykazuje zn\u00e1mky vn\u011bj\u0161\u00edch net\u011bsnost\u00ed, jako je kap\u00e1n\u00ed nebo hromad\u011bn\u00ed hydraulick\u00e9 kapaliny po cel\u00e9m v\u00e1lci. Pokud to neznamen\u00e1 konkr\u00e9tn\u011b vnit\u0159n\u00ed net\u011bsnost, m\u016f\u017ee to nazna\u010dovat p\u0159\u00edtomnost probl\u00e9mu.<\/p>\n

2. Kontrola vn\u011bj\u0161\u00edho \u00faniku: D\u016fkladn\u011b o\u010dist\u011bte vn\u011bj\u0161\u00ed povrchy v\u00e1lce. Pot\u00e9 aktivujte hydraulick\u00fd syst\u00e9m, abyste natlakovali v\u00e1lec, a z\u00e1rove\u0148 sledujte vn\u011bj\u0161\u00ed povrchy, zda nevykazuj\u00ed zn\u00e1mky \u00faniku hydraulick\u00e9 kapaliny. Pokud nedoch\u00e1z\u00ed k \u017e\u00e1dn\u00e9mu vn\u011bj\u0161\u00edmu \u00faniku, m\u016f\u017ee to znamenat, \u017ee \u00fanik je vnit\u0159n\u00ed.<\/p>\n

3. Kontrola posunu v\u00e1lce: Namontujte hydraulick\u00fd v\u00e1lec v chr\u00e1n\u011bn\u00e9 poloze a zcela vysu\u0148te p\u00edstn\u00ed ty\u010d.

Pokud se v\u00e1lec za\u010dne postupn\u011b zasouvat nebo posunovat dovnit\u0159 bez nutnosti p\u016fsoben\u00ed jak\u00e9koli vn\u011bj\u0161\u00ed s\u00edly, m\u016f\u017ee to b\u00fdt zn\u00e1mkou vnit\u0159n\u00ed net\u011bsnost<\/a>.<\/p>\n

4. Zkou\u0161ka p\u00e1dem: Pro tuto kontrolu budete pot\u0159ebovat tenzometr a uzn\u00e1van\u00fd zdroj nap\u011bt\u00ed, nap\u0159\u00edklad V\u00fdrobce hydraulick\u00fdch v\u00e1lc\u016f z \u010c\u00edny<\/a> \u010derpadlo. P\u0159ipojte tlakom\u011br k v\u00e1lci a natlakujte jej na ide\u00e1ln\u00ed \u00farove\u0148. Sledujte tlakom\u011br po ur\u010ditou dobu. Pokud tlak drasticky klesne bez nutnosti jak\u00e9hokoli vn\u011bj\u0161\u00edho zat\u00ed\u017een\u00ed nebo pohybu, m\u016f\u017ee to znamenat vnit\u0159n\u00ed net\u011bsnost.<\/p>\n

5. Zkou\u0161ka obtoku: V n\u011bkter\u00fdch p\u0159\u00edpadech lze prov\u00e9st kontrolu obtoku, aby se zjistila vnit\u0159n\u00ed net\u011bsnost. To zahrnuje kr\u00e1tk\u00e9 obtokov\u00e1n\u00ed v\u00e1lce p\u0159ipojen\u00edm hydraulick\u00fdch trubek p\u0159\u00edmo ke v\u0161em ostatn\u00edm hydraulick\u00fdm v\u00e1lc\u016fm, ani\u017e by byl v\u00e1lec v okruhu. Pokud po obtoku v\u00e1lce nedoch\u00e1z\u00ed k \u017e\u00e1dn\u00e9 net\u011bsnosti, nazna\u010duje to, \u017ee zdrojem net\u011bsnosti by mohla b\u00fdt vnit\u0159n\u00ed t\u011bsn\u011bn\u00ed v\u00e1lce.<\/p>\n

Je opravdu d\u016fle\u017eit\u00e9 si uv\u011bdomit, \u017ee tyto metody mohou pomoci odhalit existenci vnit\u0159n\u00edho \u00faniku, ale nemus\u00ed p\u0159esn\u011b ur\u010dit m\u00edsto nebo p\u0159\u00ed\u010dinu \u00faniku. Pokud m\u00e1te podez\u0159en\u00ed na vnit\u0159n\u00ed \u00fanik v hydraulick\u00e9m v\u00e1lci, doporu\u010duje se poradit se s kvalifikovan\u00fdm hydraulick\u00fdm technikem, kter\u00fd m\u016f\u017ee prov\u00e9st komplexn\u00ed kontrolu a poskytnout vhodn\u00e9 tipy na opravu nebo v\u00fdm\u011bnu.<\/p>","protected":false},"excerpt":{"rendered":"
