Eshabhu laseJinbin, abasebenzi basebenza ngensimbi engagqwaliamasango e-penstock. Isango le-penstock elinamathiselwe odongeni lensimbi engagqwali lithandwa kakhulu emikhakheni yokonga amanzi kanye nokuhlinzekwa kwamanzi kanye nokugeleza kwamanzi. Isizathu esiyinhloko sisezinzuzweni zalo ezingokwemvelo ngobukhulu obuhlukahlukene njengezinto zokwakha, isakhiwo, kanye nokusetshenziswa. Lezi zinzuzo ziyasekelana, zakha ukuncintisana okuphelele okudlula kude okwamasango endabuko. (Abakhiqizi be-Penstock)

Izakhiwo zezinto ezibonakalayo ziyisisekelo esiyisisekelo sokusungulwa kwayo. Umzimba oyinhloko wenziwe ngensimbi engagqwali engu-304 noma engu-316 yokudla, engagcini nje ngokuba nokumelana okukhulu nama-acid, ama-alkali kanye nokugqwala, futhi engamelana nokuguguleka kwezinto ezihlukahlukene ezigqwalisayo, kodwa futhi ingakwazi ukuzivumelanisa nokucwiliswa isikhathi eside ezindaweni ezinomswakama nezicebile ngamanzi, igweme izinkinga zokugqwala kalula nokuguga kwamasango ensimbi endabuko, futhi iqinisekise ukuzinza kwesakhiwo kanye nokuphepha kokusetshenziswa kwesango elivela emthonjeni.

Isakhiwo esiyingqayizivele esifakwe odongeni sinikeza izinzuzo ezibalulekile zokufaka. Asikho isidingo sokuthela isisekelo esinzima se-pier. Singaxhunywa ngqo odongeni noma odongeni lwechibi ukuze kufakwe okuqinile, okwenza kube lula kakhulu inqubo yokwakha izakhiwo futhi kuncishiswe izindleko zephrojekthi iyonke. Umklamo waso omncane ungavumelana nezimo ezincishisiwe zesikhala njengamanethiwekhi amapayipi amadala namakamelo okupompa amancane, okuxazulula ngempumelelo inkinga yezidingo eziphezulu zesikhala sokufaka amasango endabuko okungena.

Inezinhlobo eziningi zezimo ezisebenzayo kanye nokuzivumelanisa nezimo okunamandla. Kungakhathaliseki ukuthi uhlelo lwesibili lokuphakelwa kwamanzi lwezakhiwo zomphakathi, iziteshi zokunisela zokukhiqiza kwezolimo, noma amanethiwekhi okukhipha amanzi kanye nezindawo zokuhlanza indle emkhakheni wezimboni, konke kungahlangabezana nezidingo ngokusebenza kwawo okuzinzile kokuvula nokuvala kanye namakhono okulawula aguquguqukayo, futhi akuvinjelwa ububanzi obujwayelekile bokushisa okuphakathi kanye nokucindezela.

Ukulula kokugcinwa nokuqina kwakha inzuzo ephindwe kabili kwezomnotho. Ubuso bensimbi engagqwali bubushelelezi futhi buqinile, okwenza kube nzima ukuthi ukungcola nokungcola kunamathele. Ukugcinwa kwansuku zonke kudinga kuphela ukuhlanzwa okulula futhi akudingi ukususwa kokugqwala njalo noma ukupenda. Izindleko zokugcinwa kwaminyaka yonke ziphansi kakhulu. Ngesikhathi esifanayo, i-valve yensimbi engagqwali inamandla aphezulu esakhiwo, ukumelana nokuguguleka okunamandla, kanye nokuphila kwenkonzo okumaphakathi okudlula kakhulu okwamasango endabuko, okunciphisa imvamisa yokufakwa esikhundleni kanye nokutshalwa kwezimali okulandelayo.
