Lapho onjiniyela kanye nochwepheshe be-metro bekhetha ipulatifomu ye-granite enembile yokulinganisa okudingakalayo kanye nemisebenzi yokuhlanganisa, isinqumo sokugcina sivame ukugxila kupharamitha ebonakala ilula: ukujiya kwayo. Kodwa-ke, ukujiya kwepuleti lobuso le-granite kungaphezu kakhulu kobukhulu obulula—yisici esiyisisekelo esinquma umthamo wayo womthwalo, ukumelana nokudlidliza, futhi ekugcineni, ikhono layo lokugcina ukuzinza kobukhulu besikhathi eside.
Ngezinhlelo zokusebenza ezinembe kakhulu, ubukhulu abukhethwa ngokungahleliwe; kubalwa kobunjiniyela okubalulekile okusekelwe ezindinganisweni ezimisiwe kanye nezimiso eziqinile zokuphambuka komshini.
Izinga Lobunjiniyela Elingemuva Kokunqunywa Kokujiya
Inhloso eyinhloko yesikhulumi esinembile ukusebenza njengendilinga yokubhekisela eyisicaba ngokuphelele, engashukumi. Ngakho-ke, ubukhulu bepuleti lobuso be-granite bubalwa ngokuyinhloko ukuqinisekisa ukuthi ngaphansi komthwalo walo omkhulu olindelwe, ukuthamba kwepuleti kuhlala ngaphakathi kwebanga lokubekezelela elibekiwe (isb., Ibanga AA, A, noma B).
Lo mklamo wesakhiwo unamathela eziqondisweni ezihamba phambili embonini, njenge-ASME B89.3.7 standard. Isimiso esiyinhloko ekunqumeni ubukhulu ukunciphisa ukuphambuka noma ukugoba. Sibala ubukhulu obudingekayo ngokucabangela izakhiwo ze-granite—ikakhulukazi i-Young's Modulus of Elasticity yayo (isilinganiso sokuqina)—kanye nobukhulu bepuleti kanye nomthwalo olindelekile.
Izinga Legunya Lomthamo Womthwalo
Indinganiso ye-ASME eyamukelwa kabanzi ixhumanisa ukujiya ngqo nomthamo wepuleti wokuthwala umthwalo kusetshenziswa umkhawulo othile wokuphepha:
Umthetho Wokuzinza: Ipulatifomu yegranite kumele ibe nkulu ngokwanele ukusekela umthwalo ojwayelekile osetshenziswa enkabeni yepuleti, ngaphandle kokuphambukisa ipuleti nganoma iyiphi i-diagonal ngaphezu kwengxenye yokubekezelela kwayo ukuthamba.
Lesi sidingo siqinisekisa ukuthi ukujiya kunikeza ukuqina okudingekayo ukuze kuthathwe isisindo esisetshenzisiwe ngenkathi kugcinwa ukunemba kwe-sub-micron. Ukuze kube nepulatifomu enkulu noma elayishwe kakhulu, ukujiya okudingekayo kuyanda kakhulu ukuze kulwiswane nesikhathi sokugoba esiphezulu.
Ubukhulu: Isici Esithathu Ekuqineni Okunembile
Ubukhulu beplatifomu busebenza njenge-amplifier eqondile yokuqina kwesakhiwo sayo. Ipuleti elijiyile linikeza izinzuzo ezintathu ezinkulu ezixhumene ezibalulekile ekulinganisweni okunembile:
1. Umthamo Womthwalo Othuthukisiwe kanye Nokugcinwa Kokuthamba
Ubukhulu bubalulekile ekumelaneni nomzuzu wokugoba obangelwa izinto ezisindayo, njengemishini yokulinganisa emikhulu (ama-CMM) noma izingxenye ezisindayo. Ukukhetha ubukhulu obudlula isidingo esincane kunikeza umkhawulo wokuphepha obalulekile. Lokhu okungeziwe kunikeza ipulatifomu isisindo esidingekayo kanye nesakhiwo sangaphakathi sokusabalalisa umthwalo ngempumelelo, ngaleyo ndlela kunciphisa kakhulu ukuphambuka kwepuleti nokuqinisekisa ukuthi indawo edingekayo igcinwa ithambile kuyo yonke impilo yepulatifomu.
2. Ukuqina Okunamandla Okuthuthukisiwe kanye Nokunciphisa Ukudlidliza
I-granite slab ejiyile nesindayo ngokwemvelo inobukhulu obukhulu, okuyinto ebalulekile ekunciphiseni umsindo wemishini kanye ne-acoustic. Ipulatifomu enkulu inemvamisa ephansi yemvelo, okwenza ingabi sengozini enkulu yokudlidliza kwangaphandle kanye nomsebenzi wokuzamazama ovamile ezindaweni zezimboni. Lokhu kunciphisa okungapheli kubalulekile ekuhlolweni okuphezulu kokukhanya kanye nezinhlelo zokuqondanisa nge-laser lapho ngisho nokunyakaza okuncane kakhulu kungonakalisa inqubo.
3. Ukuthuthukisa I-Thermal Inertia
Ukwanda komthamo wezinto zokwakha kunciphisa ukuguquguquka kwezinga lokushisa. Ngenkathi i-granite esezingeni eliphezulu isivele ine-coefficient ephansi kakhulu yokwanda kokushisa, ukujiya okukhulu kunikeza i-inertia ephezulu yokushisa. Lokhu kuvimbela ukuguquguquka kokushisa okusheshayo, okungafaniyo okungenzeka lapho imishini ishisa noma imijikelezo yomoya, okuqinisekisa ukuthi i-geometry yokubhekisela yesikhulumi ihlala ihambisana futhi izinzile phakathi nezikhathi zokusebenza ezinde.
Ezweni lobunjiniyela bokunemba, ubukhulu beplatifomu yegranite akuyona into okufanele uyinciphise ukuze wonge izindleko, kodwa yinto eyisisekelo yokwakha ukuze ulungiselele, ukuqinisekisa ukuthi ukusetha kwakho kuletha imiphumela ephindaphindwayo nelandelekayo edingwa ukukhiqiza kwanamuhla.
