OwaziwayoUmshini wokugcwalisa i-PUikakhulukazi ikhiqiza imikhiqizo yochungechunge lwe-PU.Umzimba wonke womshini wakhiwe uhlaka lwensimbi engagqwali, futhi indlela yokuxuba umthelela isetshenziselwa ukwenza ukuhlanganiswa ngokulinganayo.Ngakho-ke, yini okudingeka siyenze ukuze silondoloze umshini wethu wokugwedla we-PU?

1. Uhlelo lokucindezela komoya lomshini we-PU ogwebulile

Imishini yethu idinga ukukhishwa amanzi kanye ngesonto ukuze kuqinisekiswe ukugcotshwa kwezingxenye.Singasebenzisa futhi i-petroleum jelly ukugcoba uhlaka lwekhanda le-dispenser kanye nekhanda lokulinganisa.Khipha i-valve yokukhipha ithangi likaphethiloli njalo ngenyanga ukuze uhlanze amaphaseji okungena kuwo kanye nezingxenye zokuvala.Ungakwazi futhi ukufaka ibhotela ngaphakathi ukuze uvikele ukugcoba.

2. Uhlelo lwe-Hydraulic lomshini we-PU ogwebulile

Isihlungi akufanele sihlanzwe njalo.Ungayihlanza njalo ezinyangeni eziyisithupha.Uzodinga ukushintsha isihlungi njalo ekuhlanzweni okubili.Shintsha uwoyela we-hydraulic njalo ezinyangeni eziyisithupha.Ungakwazi futhi ukugcoba nge-petroleum jelly noma uwoyela we-hydraulic.Lapho ushintsha uwoyela omusha minyaka yonke, izingxenye zangaphakathi zemishini yethangi likawoyela kanye nevalvu yokuhlehlisa amanzi kufanele kuhlanzwe ngesikhathi esisodwa.I-valve ye-hydraulic diverter iphila impilo yesevisi cishe iminyaka emibili.Kufanele sikukhumbule lokhu.

3. Uhlelo lwempahla eluhlaza yomshini we-PU ogwebulile

Ukucindezela kwethangi lempahla eluhlaza kudinga ukuthi umoya owomile ube yinitrogen.Njalo ngonyaka sidinga ukususa isihlungi futhi sihlanze ingaphakathi nge-methylene chloride kanye nebhulashi lethusi, bese sisebenzisa i-DOP ukuhlanza iphepha lokuhlunga le-methylene chloride esele.Izigxivizo zephampu eguquguqukayo yezinto ezimnyama zishintshwa njalo ngekota, futhi izimpawu zephampu yempahla emhlophe zishintshwa njalo ngemva kwamakwata amabili.Ama-O-rings ekhanda lokulinganisa nekhanda elikhipha amanzi kufanele ashintshwe njalo ezinyangeni eziyisithupha.

4. Amakhono okuxuba omshini wokugcwalisa amagwebu we-PU

Ungawuhlikihli umzimba wombhobho ngaphandle uma kukhona ukungasebenzi kahle.Ikhanda lombhobho liphila isikhathi eside cishe ngemijovo engu-500,000 futhi lingasetshenziswa ngokuqhubekayo ngemva kokulungiswa.

5. Ukuphathwa kokuma komshini we-PU ogwebulile

Uma kungakapheli isonto, asikho isidingo sokuphatha ngokweqile.Uma isikhathi sokuphumula siside, i-feedstock idinga ukudlula umjikelezo wengcindezi ephansi lapho uqala umshini, futhi ngezikhathi ezithile umjikelezo omfushane (cishe imizuzwana eyi-10) umfutho ophezulu (cishe izikhathi ezi-4 kuya kwezi-5).
