Thetha malunga nobudlelwane obunxantathu phakathi koxinzelelo lwegama, uxinzelelo loyilo kunye noxinzelelo lokusebenza

1. Yintoni i-PN yoxinzelelo lwegama (MPa)?

Ixabiso lesalathiso elinxulumene namandla okumelana noxinzelelo lwamacandelo enkqubo yemibhobho ibhekisa kuyilo olunikiweyo uxinzelelo olunxulumene namandla omatshini amacandelo emibhobho.Uxinzelelo oluncinci lubonakaliswa ngokubanzi yi-PN.

(1) Uxinzelelo oluncinci - amandla oxinzelelo lwemveliso kwiqondo lokushisa lokubhekisela, elichazwe kwi-PN, iyunithi: i-MPa.

(2) Ubushushu bereferensi: Izinto ezahlukeneyo zineengqinisiso ezahlukeneyo zobushushu.Umzekelo, ubushushu bereferensi yentsimbi yi-250 ° C

(3) Uxinzelelo oluncinci 1.0Mpa, luchazwe njenge: PN 1.0 Mpa

2. Yintoni uxinzelelo lomsebenzi?

Ibhekiselele kuxinzelelo oluphezulu oluxeliweyo ngokobunzulu bobushushu bokusebenza bombhobho ogqithisiweyo phakathi kuwo onke amanqanaba okhuseleko lwenkqubo yemibhobho.Uxinzelelo lokusebenza lubonakaliswa ngokubanzi kwiPt.

3. Yintoni uxinzelelo loyilo?

Ibhekisa kuxinzelelo oluphezulu olukhawulezileyo lwenkqubo yombhobho wonikezelo lwamanzi olusebenza kudonga lwangaphakathi lombhobho.Ngokuqhelekileyo, isixa soxinzelelo olusebenzayo kunye noxinzelelo lwesando lwamanzi olushiyekileyo lusetyenziswa.Uxinzelelo loyilo lubonakaliswa ngokubanzi kwiPe.

4. Uxinzelelo lovavanyo

Uxinzelelo oluza kufikelelwa lucaciswe kuvavanyo lwamandla oxinzelelo kunye nokuqina komoya kwimibhobho, izitya okanye izixhobo.Uxinzelelo lovavanyo lubonakaliswa ngokubanzi kwiNdumiso.

5. Ubudlelwane phakathi koxinzelelo lwegama, uxinzelelo lokusebenza kunye noxinzelelo loyilo

Uxinzelelo lwegama luxinzelelo oluqhelekileyo oluchazwe ngokufanelekileyo ukulungiselela ukuyila, ukuvelisa kunye nokusetyenziswa.Iyunithi yolu xinzelelo lwegama ngokwenene luxinzelelo, kwaye uxinzelelo ligama eliqhelekileyo kwisiTshayina, kwaye iyunithi "Pa" endaweni ye "N".Uxinzelelo lwegama kwisiNgesi yi-nominal pres-surenomina: l egameni okanye kwimo kodwa kungekhona ngokwenyani (igama, igama).Uxinzelelo lwegama lomkhumbi woxinzelelo lubhekiselele kuxinzelelo lwegama le-flange yomkhumbi woxinzelelo.Uxinzelelo oluncinci lwe-flange yesitya soxinzelelo luhlukaniswe ngokubanzi ngamabakala angama-7, oko kukuthi 0.25, 0.60, 1.00, 1.60, 2.50, 4.00, 6.40MPa.Uxinzelelo loyilo = 1.5 × uxinzelelo lokusebenza.

Uxinzelelo olusebenzayo luvela ekubaleni kwe-hydraulic yomnatha wombhobho.

6. Ubudlelwane

Uxinzelelo lovavanyo> uxinzelelo lwegama> uxinzelelo loyilo> uxinzelelo lokusebenza

Uxinzelelo loyilo = 1.5 × uxinzelelo lokusebenza (ngokuqhelekileyo)
