Dopravn\u00edk vyzer\u00e1 ako jeden z jednoduch\u0161\u00edch typov strojov na riadenie. St\u00e1la r\u00fdchlos\u0165, predv\u00eddate\u013en\u00e9 za\u0165a\u017eenie, dlh\u00e9 doby prev\u00e1dzky \u2013 na papieri vyzer\u00e1 \u0161pecifik\u00e1cia jednoducho.

Prv\u00fdm probl\u00e9mom je rozbehov\u00fd kr\u00fatiaci moment. Za\u0165a\u017een\u00fd p\u00e1sov\u00fd dopravn\u00edk m\u00f4\u017ee vy\u017eadova\u0165 2 a\u017e 3-n\u00e1sobok be\u017en\u00e9ho kr\u00fatiaceho momentu, aby sa rozbehol z pokoja, najm\u00e4 v chladnom prostred\u00ed, kde p\u00e1s stuhne a materi\u00e1l na p\u00e1se sa usad\u00ed. Ak z\u00e1vitovkov\u00fd reduk\u010dn\u00fd prevod<\/strong> je dimenzovan\u00fd iba na prev\u00e1dzkov\u00e9 za\u0165a\u017eenie, opakovan\u00e9 rozbehov\u00e9 \u0161pi\u010dky nar\u00fa\u0161aj\u00fa z\u00e1ber ozuben\u00fdch kolies a predp\u00e4tie lo\u017eiska ove\u013ea r\u00fdchlej\u0161ie, ako nazna\u010duj\u00fa menovit\u00e9 prev\u00e1dzkov\u00e9 hodiny.<\/p>\n

Druh\u00fdm faktorom je teplo generovan\u00e9 po\u010das nepretr\u017eitej prev\u00e1dzky. Mnoh\u00e9 v\u00fdrobn\u00e9 linky v K\u00f3rei a susedn\u00fdch trhoch be\u017eia 16 a\u017e 24 hod\u00edn denne.

Toto teplo sa hromad\u00ed po\u010das dlh\u00fdch prev\u00e1dzkov\u00fdch obdob\u00ed, \u010d\u00edm sa zni\u017euje viskozita maziva. Akon\u00e1hle sa olejov\u00fd film sten\u010d\u00ed, za\u010d\u00edna sa kontakt kovu s kovom na z\u00e1vitovkov\u00e9 koleso<\/a> povrch \u2013 opotrebovanie sa zr\u00fdch\u013euje sp\u00f4sobom, ktor\u00fd sa po zastaven\u00ed a ochladen\u00ed stroja neobnov\u00ed.<\/p>\n

Tret\u00edm faktorom je rozmanitos\u0165 profilov za\u0165a\u017eenia v r\u00e1mci jedn\u00e9ho zariadenia. Logistick\u00e9 centrum m\u00f4\u017ee prev\u00e1dzkova\u0165 rovnak\u00fd model reduk\u010dn\u00fd ventil so z\u00e1vitovkov\u00fdm prevodom<\/strong> na plochom triediacom dopravn\u00edku, \u0161ikmej nakladacej rampe a \u0161pir\u00e1lovej akumula\u010dnej dr\u00e1he.
