Ziyini izimvu zamanzi ezenziwe ngomshini?Imishini yamandla enamashafu ajikelezayo, njengamaphampu nama-compressor, avame ukubizwa ngokuthi “imishini ejikelezayo”.I-Mechanical seal iwuhlobo lokupakisha olufakwe ku-shaft yokudlulisa amandla emishini ejikelezayo.Zinezinhlobonhlobo zezicelo, kusukela ezimotweni, imikhumbi, amarokhethi kanye nemishini yezitshalo zezimboni kuya ezintweni zokuhlala.
Uyini umsebenzi oyinhloko we-mechanical seal?
Izigxivizo zemishini zenzelwe ukuvimbela uketshezi (amanzi noma uwoyela) olusetshenziswa umshini ukuthi lungavuzi luye endaweni yangaphandle (umkhathi noma amanzi).Lo msebenzi we-mechanical seal usiza ukuvimbela ukungcoliswa kwemvelo, ukonga amandla nokuphepha komshini ngokuthuthukisa ukusebenza kahle komshini.
Uma i-mechanical seal noma ukupakishwa kwe-gland kungasetshenziswa, uketshezi luzovuza ngegebe eliphakathi kwe-shaft nomzimba.Uma kuphela ukuvimbela ukuvuza komshini, kusebenza kahle ukusebenzisa into yokuvala ebizwa ngokuthi ukupakisha ukuvala ku-shaft.Indandatho ehlukile ifakwe ku-shaft kanye negobolondo lomshini ukuze kuncishiswe ukuvuza koketshezi olusetshenziswa emshinini ngaphandle kokuthinta amandla okujikeleza kwe-shaft.Ukuqinisekisa lokhu, ingxenye ngayinye ikhiqizwa ngendlela enembile.I-Mechanical seal ingavimbela ukuvuza kwezinto eziyingozi ngisho nangaphansi kwezimo ezinzima zobunzima bemishini noma ukucindezela okukhulu kanye nesivinini esikhulu.
Ubuchwepheshe ngemuva seal mechanical
Ngenxa yemisebenzi engenhla kanye nezinhlelo zokusebenza, ubuchwepheshe be-mechanical seal buyisamba sobunjiniyela bemishini kanye nobuchwepheshe bokusebenza komzimba.Ngokuqondile, umnyombo wobuchwepheshe be-mechanical seal ubuchwepheshe be-Tribology (i-friction, wear and lubrication), obusetshenziselwa ukulawula indawo ehlanganayo (eshelelayo) phakathi kwendandatho engaguquki nendandatho ezungezayo.Uphawu lomshini onalo msebenzi alukwazi nje ukuvimbela uketshezi noma igesi ecutshungulwa umshini ukuthi ungangeni ngaphandle, kodwa futhi uthuthukise ukusebenza kahle komshini, ukuze usize ukufeza ukonga amandla nokuvimbela ukungcoliswa kwemvelo.
