Ziyini izimvu zamanzi ezenziwe ngomshini?

Imishini kagesi ene-shaft ejikelezayo, njengamaphampu nama-compressor, ngokuvamile yaziwa ngokuthi “imishini ejikelezayo.” Izigxivizo zemishini ziwuhlobo lokupakisha olufakwe ku-shaft yokudlulisa amandla yomshini ojikelezayo. Asetshenziswa ezinhlelweni ezahlukahlukene kusukela ezimotweni, imikhumbi, amarokhethi kanye nemishini yezitshalo zezimboni, kuya kumishini yokuhlala.

Izigxivizo zemishini zenzelwe ukuvimbela uketshezi (amanzi noma uwoyela) olusetshenziswa umshini ukuthi lungavuzi luye endaweni engaphandle (umkhathi noma amanzi amaningi). Le ndima yezigxivizo zemishini inomthelela ekuvimbeleni ukungcoliswa kwemvelo, ukonga amandla ngokusebenzisa ukusebenza kahle komshini, kanye nokuphepha komshini.

Okuboniswe ngezansi ukubuka kwengxenye yomshini ozungezayo odinga ukufakwa kophawu lomshini. Lo mshini unomkhumbi omkhulu kanye ne-shaft ejikelezayo phakathi nendawo yomkhumbi (isb, i-mixer). Umdwebo ubonisa imiphumela yamacala ane-mechanical seal nangenayo.

Amacala anophawu nangenawo ngomshini

Ngaphandle kophawu

Uketshezi luyavuza.

Ngokupakishwa kwezindlala (stuffing)

I-eksisi igqoka.

Idinga ukuvuza okuthile (ukugcoba) ukuvimbela ukuguga.

Ngophawu lwemishini

I-eksisi ayigqoki.
Akukho ukuvuza.

Lokhu kulawula ukuvuza koketshezi kubizwa ngokuthi “ukubeka uphawu” embonini yezinsimbi zomshini.

Ngaphandle kophawu
Uma kungasebenzi uphawu lomshini noma ukupakishwa kwezindlala, uketshezi luvuza endaweni evulekile phakathi kwe-shaft nomzimba womshini.

Ngokupakisha indlala
Uma inhloso kuwukuvimbela kuphela ukuvuza emshinini, kuyasebenza ukusebenzisa impahla yophawu eyaziwa ngokuthi ukupakisha indlala ku-shaft. Kodwa-ke, indlala epakisha inxeba eliqinile eduze kwe-shaft ivimbela ukunyakaza kwe-shaft, okuholela ekugugeni kwe-shaft futhi ngenxa yalokho kudinga okokugcoba ngesikhathi sokusetshenziswa.

Ngophawu lwemishini
Izindandatho ezihlukene zifakwe ku-shaft nasezindlini zomshini ukuze kuvunyelwe ukuvuza okuncane koketshezi olusetshenziswa umshini ngaphandle kokuthinta amandla ajikelezayo we-shaft.
Ukuqinisekisa lokhu, ingxenye ngayinye yakhiwe ngokomklamo onembile. Izigxivizo zemishini zivimbela ukuvuza ngisho nezinto eziyingozi okunzima ukuziphatha ngomshini noma ngaphansi kwezimo ezinzima zokucindezela okukhulu kanye nesivinini esikhulu sokuzungeza.
