Izihlungi ezijwayelekile zepompo ye-vacuum
Umsebenzi wepompo ye-vacuumisihlungi sokungenaukusiza ukuhlukanisa ukungcola lapho i-vacuum futha iphampa. Ngokuya ngokungcola okuhlukene okunjengothuli, umhwamuko, isihlungi sothuli esihambisanayo noma isihlukanisi soketshezi lwegesi sikhethwa ukuze kuvinjelwe iphampu yevacuum ekumunceni ukungcola lapho ingenisa umoya, okubangela ukuthi izingxenye zangaphakathi zephampu yevacuum zilimale futhi uketshezi olusebenzayo lungcoliswe. Kuyaqondakala ukuthi isihlungi sidinga ukufakwa lapho kukhishwa i-vacuum, kodwa kungani isihlungi sidingeka futhi lapho kuphulwa i-vacuum?
Kuyini ukuphulwa kwe-vacuum?
Ukuqhekeka kwe-vacuum kusho ukuphula i-vacuum ngokulinganisa ingcindezi ngaphakathi nangaphandle kwegumbi le-vacuum. Isithombe nje sokuthi umkhiqizo ucutshungulwa ku-vacuum; ngenxa yomehluko omkhulu ekucindezelweni komoya ngaphakathi nangaphandle kwegumbi, uma ufuna ukukhipha umkhiqizo, udinga ukulinganisa ukucindezela komoya ngaphakathi nangaphandle. Ngokuvamile, i-valve isethwe ngokukhethekile emshinini we-vacuum ukuze kuzuzwe "i-vacuum breaking". Futhi isihlungi sokungena esifakwe lapha sibizwa ngokuthi isihlungi se-vacuum breaking. Ngakho isihlungi se-vacuum empeleni siyisihlungi se-inlet, sivele sinikezwe igama elihlukile ngenxa yendawo ehlukile yokufaka.
Kungani kudingekile ukufaka isihlungi sokungena lapho uphula i-vacuum?
Ngesikhathi sokusebenza kwe-vacuum, ngenxa yomehluko omkhulu ekucindezelweni komoya wangaphakathi nangaphandle, umoya uzomuncwa ngokushesha egumbini lokuphumula ngemuva kokuvulwa kwe-valve. Ngalesi sikhathi, ukungcola kwangaphandle kungase kungene egumbini le-vacuum kanye nepompo ye-vacuum kanye nomoya, kubangele ukungcola emikhiqizweni ecutshunguliwe. Ukuze uvimbele lokhu kungenzeki, isihlungi se-inlet sivame ukufakwa ku-valve. Lokhu akuvikeli nje kuphela imikhiqizo esegunjini le-vacuum, kodwa futhi kuvikela izinto zokusebenza ze-vacuum. Ngakho-ke, iisihlungi sokungenaiyadingeka futhi lapho uphula i-vacuum.
