Isingeniso somkhiqizo wokunisela ngamakhala

Ukunisela emakhaleni: ithuluzi lokuhlanza ikhala. Ngokulungisa nokulawula ukushintshwa kwe-valve eyodwa-yendlela yokukhipha amanzi kanye{2}}nendlela eyodwa{2}}ivalve yokungena komoya ngosayizi wokucindezela okufakwa ebhodleleni elinwebekayo ngesandla kanye nesivinini sokuphumuza, ukugeza amakhala okukhethekile kuthunyelwa emakhaleni, kugeleze ku-vestibule yamakhala (ingxenye evezwe ngaphandle kwekhanda), amagciwane, imigudu yamakhala, iphuma emakhaleni, iphuma emakhaleni, iphuma emqaleni, iphuma emqaleni ephuma emlonyeni. Ngalezi zindlela ezingenhla, ngosizo lwamandla omthelela wokugeleza kwamanzi anosawoti we-physiological, amagciwane e-pathogenic kanye nokungcola okunqwabelene emakhaleni kuyaphuma, ukuze ikhala likwazi ukubuyisela isimo sokuphila esivamile, libuyisele{4}}umsebenzi wokuqeda ubuthi wekhala, futhi kufezwe injongo yokuvikela ikhala.
