Mukutanga kugadzirwa kwePPR pombi, zvinhu zvitatu zvakakosha zvakanyanya zvinotariswa, zvinoti hupenyu hwebasa hwepombi, tembiricha yekushanda uye kudzvanywa kwekushanda.Izvi zvinhu zvitatu zvinokanganisa mumwe nemumwe, saka maparamita anofanirwa kusangana nezvinodiwa.

The pressure value kuti thePPR pombiinogona kumira zvinodiwa zvichienderana nehupenyu hwekugadzira pombi uye tembiricha munzvimbo yekushanda sechinhu chinodiwa.

Zvichienderana nematanho matatu ari pamusoro ehupenyu hwesevhisi, shandisa tembiricha uye shandisa kumanikidza, tinogona kupedzisa mitemo miviri:

1. Kana avhareji yehupenyu hwebasa rePPR pombi inotarwa kuva makore makumi mashanu, iyo yakakwirira yenzvimbo yekushanda tembiricha yepombi yakagadzirwa ndeye, yakaderera iyo inoenderera kushanda kumanikidza iyo PPR inogona kumira, uye zvinopesana.

2. Kana tembiricha yekugadzira yePPR pombi inodarika 70 ℃, nguva yekushanda uye kuenderera mberi kwekushanda kwePPR pombi ichaderedzwa zvikuru.Izvo chaizvo nekuda kwekuita kwakanaka kwemapombi ePPR ari pasi pe70 ° C kuti mapaipi ePPR anova akanyanya kupisa nekutonhora.pombi dzemvura, nekuti tembiricha yemvura inopisa yemumba iri pasi pe70°C.

Kune marudzi maviri ePPR pombi: pombi yemvura inotonhora uye pombi yemvura inopisa.Chii chakasiyana?

Mapombi emvura inotonhora akati detei.Kutaura zvazviri, zvinokurudzirwa kutenga zvose zviputi zvemvura inopisa, nokuti rusvingo rwemapombi emvura inopisa yakawanda uye kupikisa kwekudzivirira kwakanaka.Kune marudzi maviri emhuri dzakawanda: 6 in charge (kunze kwedhayamita 25 mm) uye 4 inotarisira (kunze kwe20 mm).

Kana iwe uchigara pane yakaderera pasi, kudzvinyirira kwemvura kwakakwirira, iwe unogona kushandisa gobvu 6-point pombi, kuitira kuti kuyerera kwemvura kuve kwakakura uye kusanyanya kukurumidza.Kana uchigara pauriri hwepamusoro, semuridzi ambotaurwa, anogara pauriri hwemakumi matatu nembiri, unofanira kusanganisa pombi dzakakora uye dzakatetepa.Inokurudzirwa kushandisa 6 nokuda kwepombi huru uye 4 yepombi yebazi kudzivirira kusakwana kwemvura kudzvinyirira kumba.
