Ikhebula le-Zero Buoyancy
Izici Zomkhiqizo
Izintambo ezingakwazi ukubutha zinezici ezinhle kakhulu njengokumelana namafutha, ukumelana nokugqwala, ukumelana ne-asidi kanye ne-alkali, ukumelana namanzi olwandle, ukumelana ne-hydrolysis, ukumelana nokuphazamiseka, amandla aphezulu okudonseka, ukumelana nokulunywa yizinhlanzi, ukuphepha okuphezulu, ukonga izinto, kanye nokunciphisa izindleko.
Ububanzi besicelo
Ikhebula elingashukumi kakhulu ligwema ukucwila ngokweqile ngenxa yesisindo sekhebula ngokwalo, okubangela umthwalo ekusebenzeni kwemishini engaphansi kwamanzi. Ikhebula lisebenzisa umklamo okhethekile wesakhiwo, ovumela ikhebula ukuthi lintante phezu kwamanzi futhi lisetshenziswe ekunwetshweni nasekudonsweni ngesikhathi sokucwila kwemishini. Ivame ukusetshenziswa ekuxhumeni amandla, ukudluliselwa kwesignali, noma ukulawula isignali yemishini engaphansi kwamanzi, isetshenziswa kakhulu emishinini yemishini yokusebenza engaphansi kwamanzi njengamarobhothi angaphansi kwamanzi, ukutholwa kwamanzi, ukwakhiwa kwamanzi, amakhamera angaphansi kwamanzi, kanye nokuqapha kwamanzi.
ingxube yomkhiqizo
1. Ukumelana kwe-DC komqhubi wekhebula oqediwe (iKlasi R) (ngokuvumelana nemithethonqubo ye-GB3956) kuzobhekisela ku-Appendix A Table 2;
2. Ukwamukela izinto zokufaka uthuli ezingangenisi manzi ezikhethekile ezingenisiwe kanye nezinto zokufaka uthuli;
3. Izinqubo ezikhethekile zokuklama nokukhiqiza;
4. Ku-20 ℃, ukumelana kokushisa akufanele kube ngaphansi kuka-50M Ω/KM;
5. Ikhebula eliqediwe kufanele likwazi ukumelana nokuhlolwa kwamandla kagesi e-AC angu-50Hz, 3.5 kV, kanye nemizuzu emi-5 ngaphandle kokuphuka.
Izinto ezivame ukusetshenziswa kakhulu zokufutha ukuze zingafuthi yi-polyurethane foam, i-copolymer foam kanye ne-composite foam. Izici zazo kanye nokusetshenziswa kwazo kuqhathaniswa kanje:
1. Igwebu le-polyurethane
Izici: Ububanzi bobuningi 0.05-0.25g/cm³， Ukujula kokusebenza akumele kudlule ama-200m;
Ukusetshenziswa: Ipayipi elintantayo, ama-booy okubopha, izikebhe ezintantayo, ukuvikela ipayipi, izintambo zokuphakamisa ipayipi, izinto ezintantayo zesikhashana eziphuthumayo;
2. Igwebu le-Copolymer
Izici: Ububanzi bobuningi 0.04-0.4g/cm³， Ukujula kokusebenza akumele kudlule u-600m noma ngaphezulu;
Ukusetshenziswa: Izinto ezintantayo ze-ROV, ukuntanta kwenkaba, ukugcwaliswa kwemigodi yezakhiwo ezinkulu ezingaphansi kolwandle, ukufakelwa kwepayipi, izinto ezintantayo zethangi elingaphansi komhlaba, kanye nama-buoy angaphansi kolwandle;
3. Izinto ze-foam ezihlanganisiwe
Izici: ububanzi bobuningi bepulasitiki ye-foam ehlanganisiwe emsulwa bungu-0.46-0.65g/cm³， Ukujula kokusebenza kuwukujula kolwandle lonke, kanti ububanzi bobuningi bepulasitiki ye-foam ehlanganisiwe bungu-0.275-0.56g/cm³， Ukujula kokusebenza kungaphakathi kuka-4000m;
Ukusetshenziswa: Kusetshenziswa kabanzi emasimini ajulile, njengezithiyo zokufutha zemishini yokuphakamisa, izithiyo zokufutha ze-ROV ezijulile, izithiyo zokufutha ze-umbilical, kanye nezithiyo zokufutha zepayipi elijulile.
