Ukunganaki ukuhlanza nokuhlola njalo kungaholela ekuqongeleleni okungalawuleki kokungcola nezinto ezingcolisayo.
2.9.2 Izixazululo zokuvimbela ukunqwabelana kwemfucumfucu
* Ukuhlolwa njalo nokuhlanzwa kwamapayipi nama-valve
Abasebenzi kufanele bahlole njalo ukuthi akukho yini okuvinjiwe, ukuguguleka noma umonakalo obangelwe ukungcola. Ngaphezu kwalokho, uhlelo kufanele luhlanzwe njalo ukuze kususwe ukungcola, ukugqwala kanye nezinye izinto ezingcolisayo. Kumapayipi aphatha uketshezi oluqukethe izinto eziqinile ezilengayo, ukufaka izikrini noma izihlungi phezulu kwevalvu kungasiza ekubambeni imfucuza ngaphambi kokuba ifike kuvalvu.
* Ukukhetha izinto
Ukusebenzisa izinto ezingagqwali njengensimbi engagqwali noma ama-alloy akhethekile ambozwe kunganciphisa ukukhiqizwa kwezinhlayiya zangaphakathi. Lezi zinto ziphinde zimelane kangcono noketshezi olugugulekayo, zivimbele ukuguguleka kanye nokuqongelela kwemfucumfucu okulandelayo.
* Izindlela zokufaka ezifanele
Ukuhlola ipayipi ukuze kutholakale ukungcola kanye nemfucumfucu ngaphambi kokufaka ivalvu kuvimbela ukungcola ukuthi kungangeni ohlelweni. Ukuqondisa kahle ivalvu nokuyiqinisa kahle kunciphisa izikhala lapho ukungcola kungahlala khona.
3. Isifinyezo
Ukwehluleka kwevalvu yebhathabhatha kanye nezixazululo zayo kuvame ukubangelwa izinkinga ezifana nokuvuza, ukuguguleka, ukugqwala kanye nokufakwa okungafanele. Izinyathelo ezisebenzayo ziqinisekisa ukusebenza kahle futhi zinciphisa ukuphazamiseka. Ukugcinwa njalo, ukufakwa okufanele kanye nokukhethwa kwezinto ezihambisanayo kubalulekile ukuze kwandiswe impilo yevalvu. Ukubonisana nomhlinzeki wevalvu yebhathabhatha ochwepheshe nokulandela imiyalelo kungathuthukisa ukuthembeka futhi kunciphise isikhathi sokungasebenzi.
