Izihluzi zempompo yokufunxa eqhelekileyo
Umsebenzi wempompo yokufunxaisihluzi sokungenakukuncedisa ukwahlula ubumdaka xa umpompo ufunxa. Ngokobumdaka obuhlukeneyo obufana nothuli, umphunga, isihluzo sothuli esihambelanayo okanye isahluli segesi-ulwelo olukhethiweyo ukuthintela impompo yokufunxa ekufunxeni ukungcola xa ithatha umoya, ibangele ukuba iindawo zangaphakathi zempompo yokufunxa zonakaliswe kwaye ulwelo olusebenzayo lungcoliseke. Iyaqondakala into yokuba isihluzi kufuneka sifakelwe xa kucocwa, kodwa kutheni isihluzo sikwafuneka xa kusaphulwa ivacuum?
Yintoni ivacuum?
Ukuqhawula ivacuum kuthetha ukwaphula ivacuum ngokulinganisa uxinzelelo ngaphakathi nangaphandle kwendawo yokufunxa. Umfanekiso nje wokuba imveliso icutshungulwa kwi-vacuum; ngenxa yomahluko omkhulu kuxinzelelo lomoya ngaphakathi nangaphandle kwegumbi, ukuba ufuna ukukhupha imveliso, kufuneka ulungelelanise uxinzelelo lomoya ngaphakathi nangaphandle. Ngokuqhelekileyo, ivalve iseti ngokukodwa kwisixhobo sokutshayela ukuphumeza "i-vacuum breaking". Kwaye isihluzo sokungena esifakwe apha sibizwa ngokuba sisihluzo esiqhekezayo sokucoca. Ke isihluzo sokucoca sisixhobo sokucoca, sinikwa nje igama elahlukileyo ngenxa yendawo eyahlukileyo yofako.
Kutheni kuyimfuneko ukufakela isihluzi sokungena xa uqhekeza ivacuum?
Ngethuba lokuqhawula i-vacuum, ngenxa yomehluko omkhulu kuxinzelelo lomoya wangaphakathi nangaphandle, umoya uya kuxutywa ngokukhawuleza kwigumbi lokucoca emva kokuba i-valve ivuliwe. Ngeli xesha, ukungcola kwangaphandle kungangena kwigumbi lokucoca kunye nempompo ye-vacuum kunye nomoya, okubangela ukungcola kwiimveliso ezicutshungulwayo. Ukuthintela oku kungenzeki, isihluzo sokungena sihlala sifakwe kwivalve. Oku akukhuseli kuphela iimveliso ezikwigumbi le-vacuum, kodwa nokukhusela izixhobo zokufunxa. Ngoko ke, iisihluzi sokungenaiyafuneka kwakhona xa uqhekeza ivacuum.
