Cineál ZGB (P) Caidéal sciodair
Feidhm Réamhrá ：
1. Feidhmíocht Hiodrálach Ard, CAD Dearadh Nua -Aimseartha, Ardéifeachtúlacht agus Ráta Abacáin Níos Lower2 Pasáiste leathan, neamh-chlogáil agus feidhmíocht mhaith NPSH.3. Glactar le séala díbeartha in éineacht le séala pacála agus séala meicniúil chun an sciodar ó sceitheadh a ráthú.4. Cinntíonn an dearadh iontaofachta MTBF fada (meán -am idir imeachtaí)5. Cinntíonn an t -imthacaí méadrach le bealaithe ola, córais bhealaithe agus fuaraithe réasúnta go n -oibreofar an t -imbhualadh faoin teocht níos ísle.
.
7. Is féidir an caidéal a oibriú i sraith le ilchéimniú laistigh de bhrú incheadaithe. Is é an brú oibre uasta incheadaithe ná 3.6 MPa.
Tá buntáiste ag an tsraith caidéil as tógáil réasúnta, ardéifeachtúlacht, oibriú iontaofa agus cothabháil éasca. Is féidir é a úsáid go forleathan chun an meascán a láimhseáil de sholaid scríobacha agus creimneacha i gcumhacht leictreach, i miotalóireacht, i mianach, i ngual, i dtionscal foirgníochta agus i dtionscal ceimiceach go háirithe chun fuinseog agus sloda a bhaint i stáisiún cumhachta leictrigh.
Gnéithe caidéil:
1. Is é an caidéal sciodair ZGB (P) an tsraith ZGB (P) ná caidéal sciodair lártheifeacha, aonchéime, aonchéime, aonchéime, cantilever. Rothlaíonn an caidéal go deiseal ó thaobh na tiomána de.
2. Is féidir na codanna fliucha de chaidéal ZGB agus ZGBP ag an trastomhas asraon céanna a bheith in -idirmhalartaithe. Tá a dtoisí suiteála imlíne ar cheann agus mar an gcéanna. Maidir leis an gcuid tiomána den chaidéal sciodair ZGB (P), glacadh leis an bhfráma scoilte cothrománach le bealaithe ola agus dhá shraith de chórais fuaraithe uisce laistigh agus lasmuigh. Más gá, is féidir uisce fuaraithe a sholáthar. Is féidir an chomhpháirt ullmhaithe le haghaidh uisce fuaraithe agus brú an uisce fuaraithe a fheiceáil i dTábla 1.
3. Baineadh úsáid as dhá chineál de shéala seafta - séala expeller in éineacht le pacáil agus séala meicniúil le haghaidh caidéal sciodair Sraith ZGB (P).
4. Moltar an séala meicniúil a sholáthraítear le huisce rónta ardbhrú nuair a fheidhmítear an caidéal sciodair i sraith (dhá chéim agus os cionn dhá chéim), agus úsáidtear an séala expeller in éineacht le pacáil i gcaidéal aonchéime.
