Kontrola vn\u00fatorn\u00fdch netesnost\u00ed v hydraulickom valci sa m\u00f4\u017ee vykona\u0165 nieko\u013ek\u00fdmi met\u00f3dami. Tu je nieko\u013eko typick\u00fdch techn\u00edk na zistenie, \u010di hydraulick\u00fd valec netesn\u00ed vn\u00fatorne:<\/p>\n

jedna. Vizu\u00e1lna kontrola: V\u00fdrobca hydraulick\u00fdch valcov v \u010c\u00edne<\/a> Vykonajte vizu\u00e1lnu kontrolu valca, \u010di neobsahuje zn\u00e1mky vonkaj\u0161\u00edch netesnost\u00ed, ako napr\u00edklad kvapkanie alebo hromadenie hydraulickej kvapaliny okolo valca. Ak to neznamen\u00e1 konkr\u00e9tne vn\u00fatorn\u00fd netesnos\u0165, m\u00f4\u017ee to nazna\u010dova\u0165 pr\u00edtomnos\u0165 probl\u00e9mu.<\/p>\n

2. Kontrola vonkaj\u0161\u00edch netesnost\u00ed: D\u00f4kladne vy\u010distite vonkaj\u0161ie povrchy valca. Potom aktivujte hydraulick\u00fd syst\u00e9m na natlakovanie valca a z\u00e1rove\u0148 sledujte vonkaj\u0161ie povrchy, \u010di neobsahuj\u00fa zn\u00e1mky \u00faniku hydraulickej kvapaliny. Ak nie je \u017eiadny vonkaj\u0161\u00ed \u00fanik, m\u00f4\u017ee to znamena\u0165, \u017ee \u00fanik je vn\u00fatorn\u00fd.<\/p>\n

3. Kontrola posunu valca: Namontujte hydraulick\u00fd valec v chr\u00e1nenej polohe a \u00faplne vysu\u0148te piestnu ty\u010d. Potom v bl\u00edzkosti ak\u00fdchko\u013evek p\u00e1kov\u00fdch ventilov, ktor\u00e9 by mohli dr\u017ea\u0165 valec vysunut\u00fd. Ak sa valec za\u010dne postupne zas\u00fava\u0165 alebo sa pos\u00fava\u0165 dovn\u00fatra bez pou\u017eitia akejko\u013evek vonkaj\u0161ej sily, m\u00f4\u017ee to by\u0165 znakom vn\u00fatorn\u00fd \u00fanik<\/a>.<\/p>\n

4.

Pripojte tlakomer k valcu a natlakujte ho na ide\u00e1lnu \u00farove\u0148. Sledujte tlakomer dlh\u0161\u00ed \u010das. Ak tlak dramaticky klesne bez potreby ak\u00e9hoko\u013evek vonkaj\u0161ieho za\u0165a\u017eenia alebo pohybu, m\u00f4\u017ee to znamena\u0165 vn\u00fatorn\u00fd \u00fanik.<\/p>\n

5. Test obtoku: V niektor\u00fdch pr\u00edpadoch je mo\u017en\u00e9 vykona\u0165 kontrolu obtoku, aby sa zistila vn\u00fatorn\u00e1 netesnos\u0165. To zah\u0155\u0148a kr\u00e1tkodob\u00e9 ob\u00eddenie valca pripojen\u00edm hydraulick\u00fdch potrub\u00ed priamo k ostatn\u00fdm hydraulick\u00fdm valcom bez valca v okruhu. Ak po ob\u00edden\u00ed valca nedoch\u00e1dza k \u017eiadnej netesnosti, nazna\u010duje to, \u017ee zdrojom netesnosti m\u00f4\u017eu by\u0165 vn\u00fatorn\u00e9 tesnenia valca.<\/p>\n

Je naozaj d\u00f4le\u017eit\u00e9 si uvedomi\u0165, \u017ee tieto postupy m\u00f4\u017eu pom\u00f4c\u0165 odhali\u0165 existenciu vn\u00fatorn\u00e9ho \u00faniku, ale nemusia presne ur\u010di\u0165 miesto alebo pr\u00ed\u010dinu \u00faniku. Ak m\u00e1te podozrenie na vn\u00fatorn\u00fd \u00fanik v hydraulickom valci, odpor\u00fa\u010da sa poradi\u0165 sa so sk\u00fasen\u00fdm hydraulick\u00fdm technikom, ktor\u00fd dok\u00e1\u017ee vykona\u0165 komplexn\u00fa kontrolu a poskytn\u00fa\u0165 vhodn\u00e9 tipy na opravu alebo v\u00fdmenu.<\/p>","protected":false},"excerpt":{"rendered":"
