Ukusebenza kokwakha kweendlela ezihlukahlukeneko zokwakha ikakhulukazi ukugoba nokulula ishidi elifuthumeleko ngokuya ngeemfuneko ezibekiweko ngokusebenzisa amandla. Iimfuneko ezisisekelo khulu zokubumba kukwenza ukujiya kweboda lomkhiqizo kube yinto efanako ngendlela ekungakghoneka ngayo. Iinzathu ezikulu zobukhulu bodonga obungalinganiko bemikhiqizo ngilezi: kokuthoma, izinga lokunwebeka kwengcenye ngayinye yephepha elakhiweko lihlukile; okwesibili, ubukhulu bejubane lokulula, okutjho bona, izinga lokugeleza kwegesi lokukhipha umoya nokufutha nofana ijubane lokuhamba lesikhunta, ifreyimu yokubopha kanye ne-plunger yokulula ngaphambi kokulula. Ukwakha kungenye indlela eqakathekileko ngemva kokufuthumala kwamapuleti, okufaka hlangana ukulawula amapharamitha aqakathekileko wezobuchwepheshe afana nokutjhisa kokwakha, ukugandeleleka kokwakha kanye nebelo lokwakha.
Ukwakha amazinga womtjhiso
Ngemva kokuthi izinto, umhlobo wenqubo kanye nemitjhini kunqunywe, izinga lokutjhisa lokwakha liyinto ekulu ethinta ikhwalithi yomkhiqizo, okuthinta ngqo ukujiya okuncani, ukusabalala kobukhulu kanye nephutha lobukhulu bomkhiqizo, begodu kuthinta ukunwebeka nokuqina komkhiqizo, begodu kuthinta ijubane lokwakha. Ngalokho-ke, kufanele kuthathwe ngokungatjho litho.
Ukwakha ukugandeleleka
Umphumela wokugandeleleka wenza bona ishidi liguquke, kodwana into leyo inamandla wokujamelana nokutjhuguluka, begodu imodyuli yayo ye-elastic yehla ngokukhula kwamazinga womtjhiso. Emazingeni womtjhiso wokubunjwa, kwaphela lokha ukugandeleleka okubangelwa mfutho ngaphakathi kwezinto kukhulu ukudlula i-elastic modulus yezinto ngalezinga lokutjhisa lapho izinto zingatjhuguluka khona. Nangabe umfutho osetjenziswa emazingeni womtjhiso athileko awanele ukukhiqiza ukudepha okwaneleko kwezinto, ukubunjwa kungakhiwa kuhle kwaphela ngokukhuphula umfutho wokubumba nofana ngokukhuphula izinga lokutjhisa lokubumba. Ngombana i-elastic modulus yezinto ezihlukahlukeneko ihlukile begodu inokuthembela okuhlukileko emazingeni womtjhiso, umfutho wokubumba uyahluka ngokuya ngomhlobo we-polymer (okufaka hlangana ubudisi bamamolekhyuli), ukujiya kweshidi kanye nokutjhisa kokubumba.
Ijubane lokwakha
Iinzathu ezikulu zobukhulu bodonga obungalinganiko bemikhiqizo ngilezi: kokuthoma, izinga lokunwebeka kwengcenye ngayinye yephepha elakhiweko lihlukile; okwesibili, ubukhulu bejubane lokulula, okutjho bona, izinga lokugeleza kwegesi lokukhipha umoya nokufutha nofana ijubane lokuhamba lesikhunta, ifreyimu yokubopha kanye ne-plunger yokulula ngaphambi kokulula. Ibelo lokwakha litjho ibelo lokudweba ipuleti (iphepha). Ukukhuphula ibelo lokwakha kunganciphisa umjikelezo wokwakha begodu kuyasiza ekwenzeni ngcono umkhiqizo. Kodwana, ukubunjwa okukhulu khulu kuzokuthinta ikhwalithi yomkhiqizo.
Siyazi bona imininingwana inquma ipumelelo nofana ukubhalelwa, njeke siphatha umkhiqizo ngamunye ngendlela ehle khulu begodu silinga ukuba ngcono ngendlela esingakghona ngayo.
