Indlela Yokukhetha Umenzi WeeValvu Zolwandle Ezifanelekileyo

Ukuba usebenza ngeenqanawa, sele uyazi oku: ayizizo zonke iindawo ezidalwe zilingana. Inqanawa ingabonakala inkulu kwaye ingenakutsha, kodwa ukhuseleko lwayo luhlala luxhomekeke kwizinto ezincinci, ezingajongwanga—ezifanaiivalvu zaselwandleEzi valve zilawula ukuhamba kwamanzi olwandle, ipetroli, ioyile, kunye ne-ballast. Khetha engalunganga, kwaye ujonge ukuvuza, ixesha lokungasebenzi, kunye nokulungiswa okubiza kakhulu. Khetha echanekileyo, kwaye unoxolo lwengqondo elwandle.

1. Amava okwenyani eLwandle

Ezinye iinkampani zithi zenza “iivalvu zasemanzini,” kodwa ngaba ziyayiqonda ngokwenene impilo elwandle? Ukugqwala kwamanzi anetyuwa, ukungcangcazela okuqhubekayo, uxinzelelo oluphezulu—akufani nokwenza iivalvu zefektri. Umenzi oneminyaka emininzi esebenza elwandle sele ejongene nezo ngxaki. Babuze ukuba zeziphi iinqanawa okanye iiprojekthi abazinikezeleyo. Imbali yabo iya kukuxelela ngaphezu kwayo nayiphi na intetho yokuthengisa.

2. Iziqinisekiso onokuzithemba

Umsebenzi waselwandle ungowehlabathi. Iivalvu zakho nazo kufuneka zihlangabezane nemigangatho yehlabathi. Khangela imvume evela kwi-DNV (eNorway), kwi-ABS (e-USA), kwi-LR (e-UK), kwi-BV (eFrance), okanye kwi-CCS (eTshayina). Ukuba umthengisi akanakukubonisa ezi zatifikethi, cinga kabini. Izatifikethi zingqina ukuba iimveliso zabo zinokwenza umsebenzi apho zibalulekileyo.

3. Iivalvu Ezichanekileyo, Kwizinto Ezifanelekileyo

Yonke inkqubo ekwibhodi ineemfuno ezahlukeneyo. Eminye imibhobho ifuna iivalvu zobhedu kuba ziyamelana nokugqwala kwamanzi olwandle. Eminye ifuna intsimbi engagqwaliyo okanye intsimbi ephosweyo ukuze iphathe uxinzelelo. Abavelisi ababalaseleyo abaniki nje ukhetho olunye okanye ezimbini. Banoluhlu olupheleleyo—iivalvu zesango, iivalvu zeglobe, iivalvu zokujonga, iivalvu zebhabhathane, iivalvu zebhola—kwizinto ezifanela inqanawa yakho.

4. Zivavanyiwe Ngaphambi kokuba Uzifumane

Ivalvu akufuneki ishiye umzi-mveliso ungavavanywanga. Buza umenzi wakho malunga novavanyo lwe-hydrostatic, uvavanyo lokuvuza, kunye nokuhlolwa kwezinto. Ukuba zisebenza phantsi kwe-ISO 9001, oko kungcono nangakumbi. Kuthetha ukuba zinolawulo oluqinileyo lomgangatho, ngoko ke awunguye oza kufumana iziphene kamva elwandle.

5. Inkonzo Ehlala Ikho

Intengiso ayifanele ibe sisiphelo sebali. Iivalvu ziyaphela. Iinxalenye zifuna ukutshintshwa. Abavelisi abalungileyo banikezela ngenkonzo emva kokuthengisa, iinxalenye ezisele, kunye nenkxaso yobugcisa. Ezona zilungileyo zihlala nawe ubomi bonke bevalvu, kungekuphela nje de i-invoyisi iphele.

6. Ngubani omnye oBathembayo

Nantsi indlela elula yokuvavanya: jonga abathengi babo. Ukuba iindawo ezinkulu zokuthutha iinqanawa, abaqhubi beenqanawa ezikude nolwandle, okanye iinkampani zokuthumela iinqanawa zehlabathi zisebenzisa iivalvu zazo, olo luphawu oluqinileyo. Umenzi othembekileyo kwihlabathi liphela unethuba elikhulu lokuhambisa iimveliso onokuthembela kuzo.
