Taura nezve hukama hwematatu pakati pezita rekumanikidza, dhizaini yekumanikidza uye kushanda nesimba

1. Chii chinonzi simba rezita rePN (MPa)?

Iko kukosha kwereferensi kwakabatana nekumanikidza kuramba kugona kwepiping system zvikamu zvinoreva dhizaini yakapihwa kudzvanywa ine chekuita nemagetsi emagetsi epombi zvikamu.Kumanikidzwa kwezita kunowanzo kuratidzwa nePN.

(1) Nominal pressure - iyo inomanikidza simba rechigadzirwa pane inotaridzirwa tembiricha, inoratidzwa muPN, unit: MPa.

(2) Reference tembiricha: Zvinhu zvakasiyana zvine tembiricha dzakasiyana dzekutarisa.Semuenzaniso, tembiricha yesimbi ndeye 250 ° C

(3) Nominal pressure 1.0Mpa, inoratidzwa se: PN 1.0 Mpa

2. Chii chinonzi stress yebasa?

Inoreva kudzvinyirira kwakanyanya kunotsanangurwa zvichienderana nehupamhi hwekushanda kwepombi inofambiswa svikiro pamatanho ese kuitira kuchengetedza kwepombi system.Kumanikidza kushanda kunowanzo kuratidzwa muPt.

3. Chii chinonzi kumanikidzwa kwekugadzira?

Inoreva kuwanda kwepakarepo kudzvanywa kwepombi yekupa mvura system inoshanda pamadziro emukati wepombi.Kazhinji, huwandu hwekumanikidzwa kwekushanda uye kusara kwemvura sando kudzvanywa kunoshandiswa.Dhizaini yekumanikidza inowanzo kuratidzwa muPe.

4. Test pressure

Dzvinyiriro yekusvikirwa inotsanangurwa kusimba rekumanikidza uye kuyedza kwemhepo yepombi, midziyo kana michina.Dzvinyiriro yebvunzo inowanzoratidzwa munaMapisarema.

5. Ukama huri pakati pezita rekumanikidza, kushanda kwekushanda uye kudzvinyirira kwekugadzira

Nominal pressure idhindiro yezita yakatsanangurwa yakatsanangurwa kuitira kureruka kwekugadzira, kugadzira uye kushandisa.Iyo unit yeiyi dzvinyiriro yezita ndeyekumanikidza, uye dzvinyiriro izita rakajairika muChinese, uye unit iri "Pa" pachinzvimbo che "N".Kudzvinyirirwa kwezita muChirungu ndekwezita pres-surenomina: l muzita kana chimiro asi kwete muchokwadi (zita, zita).Dzvinyiriro yezita remudziyo wekumanikidza inoreva kudzvanywa kwezita kweflange yemudziyo wekumanikidza.Iyo yekumanikidza yezita rekumanikidza mudziyo flange inowanzokamurwa kuita 7 mamakisi, anoti 0.25, 0.60, 1.00, 1.60, 2.50, 4.00, 6.40MPa.Dhizaini yekumanikidza = 1.5 × kushanda kumanikidza.

Kumanikidza kwekushanda kunobva ku hydraulic calculation yepombi network.

6. Ukama

Test pressure> nominal pressure> design pressure> kushanda nesimba

Dhizaini yekumanikidza = 1.5 × kushanda kumanikidza (kazhinji)
