Ekukhiqizweni kwezitsha zokupheka ze-aluminium,Inqubo yokucindezela phansi (noma "yokubuyisela phansi") ibalulekile ekudaleni amabhodwe namapani aqinile, angagobile futhi asatshalaliswa kahle ngokushisa. Umbuzo ovamile ovela kubakhiqizi uthi: Yimuphi umshini we-tonnage (pressure) odingekayo ukuze kucindezelwe phansi kwamabhodwe e-aluminium anwetshiwe? Impendulo akuyona inombolo eyodwa, njengoba incike ngqo ezintweni ezimbili ezibalulekile: usayizi kanye nephethini (umklamo) wepuleti elingezansi. Lesi sihloko sihlola lobu budlelwano futhi sinikeza isiqondiso sokukhetha imishini efanele.
Ukuqonda Inqubo Yokucindezela Okuphansi
Ukucindezela phansi kuhilela ukusebenzisa umshini wokucindezela we-hydraulic noma we-mechanical ukubopha unomphela ipuleti elihlukile, elivame ukuba likhulu (ngokuvamile i-aluminium noma insimbi engagqwali) esisekelweni somzimba webhodwe onwetshiwe nge-aluminium. Lokhu kudala iphansi elihlanganisiwe elinezingqimba eziningi. Umshini kumele usebenzise ingcindezi eyanele ukuqinisekisa ukunamathela okuphelele kuyo yonke indawo ngaphandle kokushiya izikhala zomoya, ngenkathi futhi wakha noma iyiphi iphethini yokukhulisa ukushisa oyifunayo.
Isici Esiyinhloko 1: Ukubalwa Kwengcindezi Edingekayo
Amandla okucindezela adingekayo (ngamathani) ngokuyinhloko asebenza endaweni kanye nokucindezela endaweni ngayinye.
- Ifomula: Amandla Adingekayo (Amathani) = Indawo Yokucindezela (cm²) × Ukucindezela Kweyunithi (Amathani/cm²)
- Indawo Yokucindezela: Lena indawo yonke engaphezulu kwepuleti elingezansi edinga ukuhlanganiswa, cishe ilingane no-π × (Irediyasi yaphansi kwebhodwe)².
- Ukucindezela Kweyunithi: Lena ingcindezi ethile edingekayo ukuze kuhlanganiswe futhi kwakhiwe ngempumelelo. Ekucindezelweni phansi kwebhodwe le-aluminium, lokhu kuvame ukuba phakathi kwamathani angu-2 kuya kwangu-4/cm², kuye ngokuthi izinto ziqine kangakanani kanye nobunzima bephethini. Amaphethini ajulile nayinkimbinkimbi adinga ingcindezi ephezulu yeyunithi.
Isibonelo: Ebhodweni elijwayelekile elingu-30cm ububanzi (i-radius engezansi ~15cm), indawo yokucindezela icishe ibe ngu-706 cm². Ukusebenzisa ingcindezi yeyunithi engu-2.5 tons/cm²:
Amandla Adingekayo = 706 cm² × 2.5 amathani/cm² = 1765 amathani, noma cishe amathani ayi-1800.
Ngakho-ke, ngosayizi wezimbiza zasekhaya ezivamile (ububanzi obungu-20cm-32cm), imishini enomthamo osukela kumathani angu-1500 kuya kwangu-2500 isetshenziswa kabanzi.
Isici Esiyinhloko 2: Isixhumanisi Nephethini (Umklamo) Nosayizi
- Usayizi wepuleti elingezansi:
- Ukuhlangana Okuqondile: Uma ububanzi obungezansi bukhulu, indawo yokucindezela inkulu. Ngokwefomula engenhla, lokhu kwandisa ngqo isidingo se-tonnage iyonke. Imbiza engu-36cm idinga amandla amakhulu kakhulu kunembiza engu-20cm ukuze kube nephethini efanayo.
- Iphethini (Umklamo / “Iphethini Yezimbali”):
- Ukujula Kwephethini Nobunzima: Ipuleti elingezansi livame ukuba nephethini egxiviziwe (njengezindilinga eziqondile noma igridi yezinyosi). Lokhu akukhona nje kuphela ubuhle; kuphatha ukwanda kokushisa futhi kuthuthukisa ukudluliselwa kokushisa. Amaphethini ajulile noma ayinkimbinkimbi adinga ingcindezi ephezulu ukuze akhe ngokuphelele insimbi ibe yisikhunta (ife) ngaphandle kokubuyela emuva, okuqinisekisa umbono oqinile nophelele.
- Ukuthintana Nokunamathela Komphezulu: Iphethini eyinkimbinkimbi inciphisa kancane indawo yokuthintana eseduze kodwa yandisa isidingo sokwakheka okunembile, okunomfutho ophezulu. Ukucindezela okunganele kuzoholela ephethini engachazwanga kahle kanye nokubopha okubuthakathaka emaphethelweni aphakanyisiwe.
Indlela Iphethini Nosayizi Okusebenza Ngayo Ndawonye:
- Ipuleti elikhulu elingezansi elinephethini elula nengajulile lingase likhonzwe ngumshini osekugcineni okuphansi kobubanzi bamathani ngobukhulu bawo.
- Ipuleti elincane elingezansi elinephethini ejulile kakhulu neyinkimbinkimbi lingadinga umshini one-tonnage ephezulu kunokulindelekile ukuze ubukhulu bawo bufinyelele incazelo ephelele yephethini.
- Ipuleti elikhulu elingezansi elinephethini ejulile neyinkimbinkimbi limelela isimo esinzima kakhulu, esidinga umshini othwala amathani amaningi (ngokuvamile amathani angu-2500 noma ngaphezulu) ukuze ubhekane nendawo enkulu kanye nobunzima bokwakheka.
Isiphetho kanye Nezincomo
Ukukhetha umshini ofanele wokucindezela phansi kuyibhalansi phakathi kosayizi webhodwe nomklamo wepuleti elingezansi. Njengomthetho ojwayelekile:
- Ezitsheni/emabhodweni amancane kuya kwaphakathi (kufika ku-28cm) anamaphethini ajwayelekile, umshini wokucindezela wamathani angu-1500-2000 uvame ukwanele.
- Ezitsheni ezinkulu noma ezithengiswayo (30cm nangaphezulu), noma kunoma yiliphi ibhodwe elinephethini ejulile/eyinkimbinkimbi, kunconywa umshini wokucindezela wamathani angu-2000-3000+.
Icebiso Elisebenzayo: Hlala uthintana nomkhiqizi wakho wedayi/isikhunta kanye nomhlinzeki wemishini yokucindezela. Banikeze ububanzi obuqondile, ukujiya kwezinto, kanye nesampula noma umdwebo wephethini yakho yepuleti elingezansi. Bangenza izibalo ezinembile futhi batuse ubukhulu bomshini obufanele, baqinisekise ukukhiqizwa kwekhwalithi, ukubopha okuqinile, kanye nephansi elakhiwe kahle njalo.
