Izinga lokushisa lesikhunta sepulasitiki linethonya elikhulu ekhwalithini yokubumba yomkhiqizo. Lingenye yezimo ezintathu ezinkulu zenqubo yokubumba ngomjovo. Ukuze kubumba ngomjovo ngokunemba, akukhona nje kuphela inkinga yokushisa okuphezulu nokuphansi, kodwa futhi nenkinga yokunemba kokulawula izinga lokushisa. Ngokusobala, kusekubumbeni ngokunemba komjovo. Kule nqubo, uma ukulawula izinga lokushisa kungalungile, ukugeleza kokuncibilika kwepulasitiki kanye nokusebenza kokubumba kanye nezinga lokuncibilika komkhiqizo ngeke kuzinzile, ngakho-ke ukunemba komkhiqizo oqediwe akunakuqinisekiswa. Ngokuvamile, indlela yokuhlanganisa uhlelo efana nebhokisi lokulawula izinga lokushisa kanye nendandatho yokushisa isetshenziswa ukulawula izinga lokushisa le-phantom.
1. Kunezindlela eziningana zokushisa noma ukupholisa umzimba wesikhunta sepulasitiki ukuze kulungiswe izinga lokushisa. Umusi, ukujikeleza kwamafutha ashisayo, ukujikeleza kwamanzi ashisayo kanye nokumelana kungasetshenziswa ukushisa umzimba wesikhunta. Amanzi ajikelezayo okupholisa noma amanzi okupholisa angasetshenziswa ukupholisa umzimba wesikhunta. Kwenziwa umoya. Ukuze kulungiswe izinga lokushisa lesikhunta esisetshenziswa emshinini wokubumba umjovo, ukufudumala kokumelana kanye nokupholisa ukupholisa okujikeleza kwamanzi kusetshenziswa kabanzi. Lapho isikhunta sishiswa ngokumelana, ingxenye eyisicaba ishiswa ngocingo lokumelana, ingxenye eyindilinga ishiswa ngogesi wokushisa, kanti ingaphakathi lesikhunta lishiswa ngogesi wokushisa. Isikhunta sidinga ukupholiswa ngokuhlela ipayipi lamanzi elijikelezayo ukuze liphole. Ukumelana nokufudumala kanye nokujikeleza kwamanzi okupholisa, lokhu kokubili kusebenza ngokushintshana ngokwezimo zokushisa zomzimba wesikhunta, ukuze izinga lokushisa lesikhunta lilawulwe ngaphakathi kobubanzi bokushisa obudingekayo yinqubo.
2. Izinyathelo zokuphepha zokulawula izinga lokushisa lesikhunta:
(1) Izinga lokushisa lengxenye ngayinye yesikhunta esakhayo ngemva kokushisa kufanele lifane ukuqinisekisa ukuthi ukuncibilika kunekhwalithi engcono yokugcwalisa, ukuze ikhwalithi yokubumba yomkhiqizo obunjiwe ngomjovo iqinisekiswe, futhi izinga lokudlula komkhiqizo obunjiwe ngomjovo lithuthukiswe.
(2) Ukulungiswa kwezinga lokushisa lenqubo yomzimba wesikhunta kufanele kunqunywe ubungako bokuncibilika. Ukuze kufakwe ukuncibilika okuphezulu kwesikhunta esikhunta, izinga lokushisa lomzimba wesikhunta kufanele lilungiswe kancane; kuyilapho ukuze kugcwale ukuncibilika okuphansi kwesikhunta, izinga lokushisa lomzimba wesikhunta lingancishiswa ngokufanele. Lapho ulungiselela ukukhiqizwa komjovo, izinga lokushisa lomzimba wesikhunta lingaphakathi kwezidingo zenqubo. Ukuze kuqinisekiswe izinga lokushisa elifanayo lomzimba wesikhunta, umzimba wesikhunta okushisa kwawo okudingeka inqubo yokushisa kufanele ugcinwe ekushiseni okungaguquki isikhathi esithile.
(3) Lapho kukhiqizwa imikhiqizo emikhulu yepulasitiki ngemijovo, ngenxa yenani elikhulu lokuncibilika elisetshenziswa ekubumbeni, isiteshi sokugeleza kokuncibilika sincane kakhulu, futhi umzimba omkhulu wesikhunta kumele ufudunyezwe futhi umanziswe esiteshini sokugeleza kokuncibilika ukuze kuvinjelwe isiteshi sokugeleza kokuncibilika ukuthi singabi side kakhulu. Ukupholisa ngenkathi kugeleza kwandisa i-viscosity yokuncibilika, okunciphisa ukugeleza kwezinto, kuthinte ikhwalithi yokujova kokuncibilika kanye nokugcwaliswa kwesikhunta, futhi kubangele ukuthi ukuncibilika kuphole futhi kuqine kusenesikhathi, okwenza umshini wokubumba wokujova ungenzeki.
(4) Ukuze kuncishiswe izinga lokushisa lokuncibilika ngenxa yesiteshi eside sokugeleza kokuncibilika futhi kwandiswe ukulahleka kwamandla okushisa, kufanele kwengezwe ungqimba oluvikela ukushisa nolwenza umswakama phakathi kwengxenye yokushisa ephansi yesikhala sesikhunta kanye nengxenye yokushisa ephezulu yesiteshi sokugeleza kokuncibilika.
