Okokuqala, ezi nkcazo zimbini zahlukile:
1, iqokobhe elingaqhumiyo “d”: uhlobo lwesixhobo sombane olungenaqhumiyo, iqokobhe linokumelana nayo nayiphi na isithuba esidibeneyo okanye solwakhiwo olungena kwiqokobhe ukuya kwiqokobhe lomxube oqhumayo ngaphakathi koqhumayo ngaphandle kokonakala, kwaye aliyi kubangela ulwangaphandle nge, iintlobo ngeentlobo zeegesi okanye umphunga owenziwe kukutsha kwendalo yegesi eqhumayo. (Ichazwe ngokwe-GB3836-2010) Izixhobo zangaphakathi zezinto eziqhelekileyo.
2, uhlobo lokhuseleko oluphuculweyo “e”: uhlobouhlobo lombane olungenakuqhumaOko kukuthi, izixhobo zombane mazithathe amanyathelo ongezelelweyo ukuphucula ukhuseleko lwazo, ukuthintela ukubakho kwamaqondo obushushu ayingozi, ii-arcs kunye neentlantsi eziveliswa kukusebenza okuqhelekileyo okanye phantsi kweemeko ezingaqhelekanga ezichaziweyo.
Ngamafutshane: ingaphakathi layo ngokwalo alivelisi ubushushu obuyingozi, ii-arcs kunye nokwenzeka kweentlantsi, kodwa liphucula kuphela izinga layo lokhuseleko, njengokuphucula inqanaba lokhuseleko. Izakhi zangaphakathi kufuneka zibe nezakhi ze-Ex logo (izakhi ezithintela ukuqhuma).
Okwesibini, ezi zimbini ziluhlobo olwahlukileyo lolwakhiwo lweqokobhe:
1, uhlobo olumelana nokuqhuma "d" ngenxa yesidingo sokumelana noxinzelelo lwangaphakathi lokuqhuma, ngoko ke kufuneka lwenzelwe ukukhupha ukufikelela kwamandla (ngokufutshane, umphezulu weflange), ubukhulu bodonga obuqhelekileyo beqokobhe bubukhulu kunohlobo lokhuseleko olunyusiweyo.
2, uhlobo lokhuseleko olunyusiweyo “e” kuba ingaphakathi ngokwalo alivelisi amaqondo obushushu ayingozi, ii-arcs kunye nokwenzeka kweentlantsi, ngoko ke akukho flange.
Okwesithathu, enye:
1, kuphela uhlobo olungenakuqhuma "d" kunye nohlobo olukhuselekileyo "i" olune-Ⅱ A, Ⅱ B, Ⅱ C; kwaye uhlobo olukhuselekileyo aluhlulwahlulwanga lube yi-Ⅱ A, Ⅱ B, Ⅱ C.
2, njengoko igumbi lokufaka iingcingo, isixhobo sokuqalisa esingenakuqhuma sohlobo "d" kufuneka sibe sisixhobo sokuqalisa "d" (esingenakuqhuma), indandatho yaso yokutywina xa ithelekiswa nokwanda kokhuseleko lwendandatho yokutywina ibe yinde, ukhuseleko lokungeniswa kwesixhobo lunyuke kangangoko idlula ukuze kuphuculwe ukhuseleko olusemgceni.
3, iqokobhe “d” elingaqhumiyo kufuneka lenziwe uvavanyo lwe-hydraulic (Ⅱ B 1.5 MPa / imizuzwana eli-10 yoxinzelelo lwamanzi, Ⅱ C 2.0 MPa / imizuzwana eli-10 yoxinzelelo lwamanzi), kwaye akudingi ukhuseleko olongezelelweyo.
4, iqokobhe elinokumelana nokuqhuma elifana no-“d” kufuneka lenze uvavanyo lokuchaphazeleka (ukuze likwazi ukumelana nobunzima bento yovavanyo eyi-1kg ukusuka kubude be-0.7m xa livavanywa ngokuthe nkqo ukuwisa), iqokobhe lokhuseleko elongeziweyo alilwenzi uvavanyo lokuchaphazeleka.
