Ukufakwa kwepayipi lokubumba komjovo kuvame ukuhlangana nesimo sokuthi isikhunta asikwazi ukugcwaliswa kunqubo yokucubungula. Lapho umshini wokubumba umjovo usanda kuqala ukusebenza, ngenxa yokuthi izinga lokushisa lesikhunta laliphansi kakhulu, ukulahlekelwa ukushisa kwezinto ezincibilikisiwe ze-PVC kwakukhulu, okwakujwayele ukuqiniswa kusenesikhathi, nokumelana nomgodi wokubunjwa kwakukhulu, futhi impahla yayingakwazi. gcwalisa umgodi. Lesi simo sijwayelekile futhi singokwesikhashana. Izonyamalala ngokuzenzakalelayo ngemva komjovo oqhubekayo wokubunjwa kwedijithali. Uma isikhunta singakwazi ukugcwaliswa ngaso sonke isikhathi, cabangela lezi zimo ezilandelayo futhi wenze izinguquko ezifanele:

Amabhamuza epayipini

Amabhamuza okushisa akhiqizwa ngenxa yokushisa okuphezulu. Ukushisa kwenqubo ephezulu kakhulu kuzodala amabhamuza ekuguquguqukeni kwezinto ezingavuthiwe, futhi kuzobola kancaneI-PVCimpahla yokukhiqiza amabhamuza, aziwa kakhulu ngokuthi amabhamuza ashisayo. Lungisa ngokufanelekile isivinini somjovo

Isivinini somjovo sishesha kakhulu. Ngoba inqubo yokubumba yeI-PVC-UImikhiqizo ebunjiwe yomjovo kufanele isebenzise ijubane lomjovo eliphansi kanye nomfutho womjovo ophezulu. Ijubane lomjovo lingalungiswa ngendlela efanele.

Uma isango lincane kakhulu noma isigaba sesiteshi sokugeleza sincane kakhulu, ukumelana nokugeleza kwezinto ezibonakalayo kukhulu kakhulu. Isango kanye nesigaba somgijimi singakhuliswa ukunciphisa ukumelana nokuncibilika kokugeleza.

Okuqukethwe umswakama noma okunye okuguquguqukayo ezintweni ezingavuthiwe kuphezulu kakhulu noma izinto ezingavuthiwe zigcinwe isikhathi eside kakhulu, futhi umswakama osemoyeni uyamuncwa. Lawula ngokuqinile okuqukethwe kokuguquguquka kwezinto zokusetshenziswa lapho uthenga izinto ezingavuthiwe, futhi izinto ezingavuthiwe neziyisizayo akufanele zigcinwe isikhathi eside kakhulu ngezikhathi noma izifunda ezinomswakama ophezulu emoyeni.

Isicwebezelisi somkhiqizo esingesihle

Isicwebezelisi esingaphezulu semikhiqizo ebunjwe ngomjovo we-PVC sihlobene kakhulu noketshezi lwezinto ze-PVC. Ngakho-ke, ukwenza ngcono i-fluidity yezinto kuyisinyathelo esibalulekile sokuthuthukisa imikhiqizo. Ngenxa yokuthi izinga lokushisa lezinto ezincibilikisiwe liphansi futhi uketshezi lwento luphansi, izinga lokushisa lokushisa lempahla lingakhuphuka ngokufanele, ikakhulukazi izinga lokushisa ku-nozzle.

Ifomula ayinangqondo, ukuze i-plasticization yezinto ezibonakalayo ingekho endaweni noma isigcwalisi siningi kakhulu, ifomula kufanele ilungiswe, futhi ikhwalithi ye-plasticization kanye ne-fluidity yezinto kufanele ithuthukiswe ngokusebenzisa inhlanganisela enengqondo yezinsiza zokucubungula, futhi inani lama-fillers kufanele lilawulwe.

Ukupholisa isikhunta okunganele, thuthukisa umphumela wokupholisa isikhunta. Uma usayizi wesango mncane kakhulu noma i-cross-section yomgijimi incane kakhulu, ukumelana kukhulu kakhulu. Ungakwazi ukwandisa i-cross-section yomgijimi ngendlela efanele, wandise isango, futhi unciphise ukumelana.

Okuqukethwe umswakama noma okunye okuguquguqukayo ezintweni ezingavuthiwe kuphezulu kakhulu. Izinto ezingavuthiwe zingomiswa ngokuphelele, noma umswakama noma ama-volatile angasuswa ngempahla. Uma i-exhaust impofu, i-groove yokukhipha ingafakwa noma indawo yesango ingashintshwa.

Kukhona imigqa yokushisela esobala

Izinga lokushisa lezinto ezincibilikisiwe liphansi, futhi izinga lokushisa lokushisa lomgqomo lingakhuphuka ngokufanele, ikakhulukazi izinga lokushisa le-nozzle kufanele lenyuke. Uma ingcindezi yomjovo noma ijubane lomjovo liphansi, ingcindezi yomjovo noma isivinini somjovo singanyuswa ngokufanelekile.

Uma izinga lokushisa lesikhunta liphansi, izinga lokushisa lesikhunta linganyuswa ngokufanelekile. Uma isango lincane kakhulu noma ingxenye yesiphambano somgijimi incane kakhulu, ungakwazi ukwandisa umgijimi noma ukhulise isango ngendlela efanele.

Ukukhipha isikhunta okungalungile, thuthukisa ukusebenza kwe-mold exhaust, engeza ama-exhaust grooves. Ivolumu ye-slug ebandayo kahle incane kakhulu, ngakho-ke umthamo we-slug obandayo ungakhuphuka ngendlela efanele.

Inani le-lubricant ne-stabilizer kufomula likhulu kakhulu, futhi inani labo lingashintshwa. Ukuhlelwa kwe-cavity akunangqondo futhi isakhiwo saso singalungiswa.

Izimpawu zokucwila ezinzima

Umfutho womjovo we-Gaoan uphansi, ngakho-ke umfutho womjovo ungakhuphuka ngendlela efanele. Isikhathi sokubamba ingcindezi esibekiwe asanele, ungakwazi ukwandisa isikhathi sokubamba ingcindezi ngendlela efanele.

Isikhathi sokupholisa esimisiwe asanele, ungakwazi ukwandisa isikhathi sokupholisa ngendlela efanele. Uma inani le-sol linganele, khulisa inani le-sol ngokufanelekile.

Ukuthuthwa kwamanzi kwesikhunta akulingani, futhi isifunda sokupholisa singalungiswa ukuze zonke izingxenye zesikhunta zipholile ngokulinganayo. Usayizi wesakhiwo sesistimu yokufaka isikhunta mncane kakhulu, futhi isango lingakhuliswa noma ubukhulu, igatsha, kanye ne-runner ye-cross-sectional izilinganiso zingakhuliswa.

Kunzima ukudiliza

Ubunzima bokudiliza bubangelwa isikhunta nenqubo engalungile, kodwa ezimweni eziningi kubangelwa indlela engafanele yokudiliza yesikhunta. Kukhona indlela yokwenza ihuku kumshini wokubhidliza, onesibopho sokuxhuma into ebandayo endaweni eyinhloko, umgijimi kanye nesango: indlela yokukhipha isebenzisa induku yokukhipha noma ipuleti eliphezulu ukuze ikhiphe umkhiqizo esikhunjeni esinyakazayo. Uma i-engeli yokudiliza inganele, ukudiliza kuzoba nzima. Kumele kube nengcindezi eyanele ye-pneumatic ngesikhathi sokukhishwa kwe-pneumatic kanye nokudilizwa. , Uma kungenjalo kuzoba nobunzima ekubumbeni. Ngaphezu kwalokho, idivayisi yokudonsa eyinhloko yendawo yokuhlukanisa, idivayisi yokudonsa ingqikithi yentambo, njll. zonke ziyizingxenye ezibalulekile esakhiweni sokudiliza, futhi ukuklama okungalungile kuzodala ubunzima bokudiliza. Ngakho-ke, ekwakhiweni kwesikhunta, indlela yokudiliza nayo iyingxenye okufanele inakwe. Mayelana nokulawulwa kwenqubo, izinga lokushisa eliphezulu kakhulu, ukudla okuningi, ukucindezela komjovo ophezulu kakhulu, kanye nesikhathi sokupholisa eside kakhulu kuzodala ubunzima bokudiliza.

Kafushane, izinkinga zekhwalithi ezehlukene zizokwenzeka ekucutshungulweni kweI-PVC-Uimikhiqizo ebunjwe ngomjovo, kodwa izizathu zalezi zinkinga zisemishinini, isikhunta, amafomula, nezinqubo. Uma nje kukhona imishini ephelele kanye nesikhunta, amafomula anengqondo nezinqubo, izinkinga zingagwenywa. Kodwa ekukhiqizeni kwangempela, lezi zinkinga zivame ukuvela, noma zivele ngaphandle kokwazi izizathu nezixazululo, kuye ngokuqoqwa kokuhlangenwe nakho. Isipiliyoni sokusebenza esicebile singesinye sezimo zokuqinisekisa umkhiqizo ophelele.
