Xa kufikwa ekukhetheni iivalvu ezifanelekileyo kwiinkqubo zaselwandle, ukhetho lunokuba nzima—ingakumbi xa izifinyezo ezifanaI-SNRkwayeI-SDNREzi ntlobo zimbini zeiivalvu zeglobhu ezingabuyiyozisetyenziswa kakhulu kwiinkqubo zemibhobho yaselwandle, kodwa zisebenza imisebenzi eyahlukileyo kancinci. Ukuqonda umahluko wazo kubalulekile ukuqinisekisa ukusebenza kweenqanawa okuthembekileyo nokusebenzayo.Kweli nqaku, siza kuhlolaumahluko phakathi kweevalvu ze-SNR kunye ne-SDNR, indlela ezisebenza ngayo, kunye nendawo ezisetyenziswa kuyo kwiinkqubo zobunjineli baselwandle.
Ukuqonda iiValve ze-SNR (iiValve zokungabuyisi)
I-SNR, mfutshaneYeka Ukungabuyi, ibhekisa kuhlobo lweivalvu yokujongaZenzelwe ukuvumela ulwelo ukuba luhambe kwicala elinye kuphela. Ezi valve zivuleka ngokuzenzekelayo xa uxinzelelo olukwipayipi ludlula uxinzelelo oluqhekekileyo kwaye ziyavaleka xa ukuhamba kujika, nto leyo ethintela ukubuya kwamanzi. Zilungele apho ukuhamba kwamanzi kufuneka khona ngaphandle kwesidingo sokungenelela komntu.
Iimpawu eziphambili zeeValve zeSNR
- ☆ Ukusebenza ngokuzenzekelayo ngokusekelwe kwicala lokuhamba
- ☆ Akukho ndlela yokulawula ngesandla
- ☆ Yenzelwe ukuthintela ukuhamba okungasemva kunye nokukhusela izixhobo
- ☆Isetyenziswa rhoqo kwimigca yokubuyisela amanzi abandayo, iinkqubo ze-ballast, kunye nemigca ye-condensate
Ukuqonda iiValve ze-SDNR (iiValve zokuMisa nezokungaBuyi)
I-SDNR, mfutshaneUkuma nokungabuyi, idibanisa imisebenzi emibini kwivalvu enye:ivalvu yokujongakwayeivalvu yeglobhuOku kuthetha ukuba ayivumeli nje kuphela ukuba ulwelo luhambe kwicala elinye kwaye ithintele ukuhamba okungasemva, kodwa ingavalwa ngesandla ukuze kumiswe ukuhamba ngokupheleleyo.Banikezela ngolawulo olongezelelekileyo kunye nokhuseleko, ingakumbi kwiimeko ezingxamisekileyo apho ukwahlulwa komgca kubaluleke kakhulu.
Iimpawu eziphambili zeeValve zeSDNR
- ☆Isebenza njengevalvu yokujonga kunye nevalvu yokumisa
- ☆Ukusebenza ngesandla ukucima ivili lesandla okanye i-actuator
- ☆Isetyenziswa kwiinkqubo ezifuna ulawulo lokuhamba komoya kunye nokusebenza okungabuyiyo
- ☆Isetyenziswa rhoqo kwimigca yeoyile yepetroli, kwiinkqubo zokuthambisa, nakwiinkqubo zokukhusela umlilo
I-SNR vs SDNR
| Uphawu | Ivalvu ye-SNR | Ivalvu ye-SDNR |
| Isikhokelo sokuhamba komoya | Indlela enye (engabuyiyo) | Indlela enye (engabuyiyo) |
| Ukuvala ngesandla | Akwenzeki | Ukuvalwa ngesandla nge-handwheel |
| Uhlobo Lokusebenza | Ngokuzenzekelayo ngokupheleleyo | Ngesandla + ngokuzenzekelayo |
| Amatyala aqhelekileyo okusetyenziswa | Ulawulo lokuhamba kwamanzi olungengolubalulekileyo, imigca yokupholisa | Iinkqubo ezibalulekileyo zokhuseleko, ioyile yepetroli, i-ballast |
| Isicelo kwiMarine | Ukukhusela ukuhamba kwamanzi kuphela | Ukhuseleko lokuhamba kwamanzi + ulawulo lwesandla |
Sebenzisana noMenzi weeValvu zaseLwandle onamava
At I-Qingdao I-Flow, sigxile ekuboneleleni ngeenkonzo ezisemgangathweni ophezuluiivalvu zaselwandlekuqukaI-SNRkwayeIivalvu zeglobhu ze-SDNR, yenzelwe ukusebenza kwiindawo ezifuna amandla olwandle. Ngamava angaphezu kweminyaka eli-10, iziqinisekiso ezifana ne-CE, i-DNV, kunye ne-ABS, kunye nabathengi kumazwe angaphezu kwama-40, siyakunceda uqinisekise ukhuseleko, ukusebenza, kunye nokuthotyelwa kwemithetho elwandle.
Ngaba ufuna izisombululo zevalvu yolwandle ezinokuthenjwa?Nxibelelana ne-I-FLOW namhlanjeukuxoxa ngeemfuno zakho.
