Zaradi polnilnega tlaka motorja se tlačni bat premakne navzdol do sedeža ventila. Tlačni bat se mora stisniti ob sedež pri tlaku 27.5 kPa (4 psi). Ko se motor ustavi, se zaradi odsotnosti polnilnega tlaka tlačni bat dvigne v odprt položaj, kar omogoči iztekanje kondenzata iz hladilnika polnilnega zraka.

Tlačni bat se mora prosto premikati, da zapre sistem, ko motor deluje. Tlačni bat se mora prosto premikati, da omogoči iztekanje kondenzata iz hladilnika polnilnega zraka, ko je motor ustavljen. Zaradi usedlin, ki nastanejo ob običajnem delovanju motorja, se lahko tlačni bat zagozdi.


OBVESTILO

Med postopki preverjanja, vzdrževanja, preizkušanja, nastavitev in popravil je treba preprečiti razlivanje tekočin. Preden odprete kakršen koli predel ali razstavite komponento, ki vsebuje tekočino, pripravite ustrezno posodo za izliv tekočine.

Glejte Posebno publikacijo, NENG2500, "Cat Dealer Service Tool Catalog" ali Posebno publikacijo, PECJ0003, "Cat Shop Supplies and Tools Catalog" za informacije o orodjih in pripomočkih, primernih za zbiranje in shranjevanje tekočin iz strojev Cat.

Z odpadnimi tekočinami ravnajte v skladu z lokalnimi okoljevarstvenimi predpisi.


  1. Odstranite ventil iz adapterja. Oglejte si ventil in preverite, ali se lahko tlačni bat prosto premika. Če ima tlačni bat težave pri premikanju, ventil očistite s topilom.

  2. Znova sestavite ventil hladilnika polnilnega zraka za odtok kondenzata. Če želite več informacij o ustreznih zateznih momentih, glejte Specifikacije, SENR3130, "Specifikacije navorov".
