1. Nominal pressure (PN)
Nominal pressure ireferensi kukosha kwakabatana nekumanikidza kuramba kugona kwepombi system zvikamu.Inoreva dhizaini yakapihwa kudzvanywa inoenderana nesimba remakanika rezvikamu zvepombi.
Iyo yekumanikidza yezita isimba rekudzivirira kwechigadzirwa (anotevera mavharuvhu) pazasi tembiricha.Zvinhu zvakasiyana-siyana zvine tembiricha dzakasiyana dzepasi uye kusimba kwesimba.
Kumanikidzwa kwezita, kunomiririrwa nechiratidzo PN (MPa).PN chiziviso chemusanganiswa wemabhii nenhamba dzinoshandiswa kureva zvine chekuita nemakanika zvivakwa uye dimensional hunhu hwepiping system zvikamu.
Kana iyo yekumanikidza yezita iri 1.0MPa, rekodha sePN10.Pasimbi yakakandwa nemhangura tembiricha yereferensi i120°C: pasimbi i200°C uye pasimbi yealloy i250°C.
2. Kumanikidzwa kwebasa (Pt)
Kudzvanywa kwekushanda kunoreva kudzvinyirira kwakanyanya kunotsanangurwa zvichibva pane yekupedzisira tembiricha yekushanda kwega rega repombi yekufambisa yepakati kuitira kushanda kwakachengeteka kwepombi system.Kungotaura, kudzvanywa kwekushanda ndiyo yakanyanya kumanikidza iyo system inogona kutsungirira panguva yekushanda kwakajairika.
3. Dhizaini kudzvanywa (Pe)
Dhizaini yedhizaini inoreva kuwanda kwepakarepo kudzvanywa kunoitwa ne pressure piping system pamadziro emukati evharuvhu.Iyo dhizaini yedhizaini pamwe chete neyakafanana dhizaini tembiricha inoshandiswa seyakagadziriswa dhizaini mamiriro, uye kukosha kwayo hakuzove kwakaderera pane kushanda kumanikidza.Kazhinji, iyo yakanyanya kudzvanywa iyo system inogona kutakura inosarudzwa panguva yekugadzira maverengero sedhizaini yekumanikidza.
4. Test pressure (PS)
Kune mavharuvhu akaiswa, The test pressure inoreva kudzvinyirirwa kunofanirwa kusvika nevhavha pakuita simba rekumanikidza uye miedzo yekudzivirira kwemhepo.
5. Hukama pakati petsanangudzo ina idzi
Nominal pressure inoreva simba rekumanikidzira patembiricha yepasi, asi kazhinji, haishande patembiricha yepasi.Sezvo kutonhora kuchichinja, simba rekumanikidza revhavha rinoshandukawo.
Kune chigadzirwa chine imwe zita rekumanikidza, kushanda nesimba kwainogona kumira kunotarirwa nekushisa kwekushanda kwepakati.
Iyo yekumanikidza yezita uye inobvumirwa kushanda kumanikidza kwechigadzirwa chimwe chete kuchave kwakasiyana pane dzakasiyana tembiricha dzekushanda.Kubva pakuona kwekuchengetedza, kudzvanywa kwekuyedza kunofanirwa kunge kwakakura kupfuura kudzvanywa kwezita.
Muinjiniya, kuyedza kumanikidza> zita kudzvanywa> dhizaini yekumanikidza> kushanda kumanikidza.
Mumwe nomumwevharafu kusanganisirabutterfly valve, vharafu yegedhiuyecheki vharafukubva kuZFA vharafu inofanira kuedzwa kuedzwa isati yatumirwa, uye muedzo wekuedza wakakura kudarika kana kuenzana nechiyero chekuedza.Kazhinji, kuedzwa kwemuviri wevharuvhu ndeye 1.5 nguva yekumanikidza kwezita, uye chisimbiso ndeye 1.1 nguva yekumanikidzwa kwezita (nguva yekuedzwa haisi pasi pe5 maminetsi).
