Chii chinonzi kumanikidzwa kwe polypropylene fittings?

Wasimbisa kuti vharuvhu yako yakarurama, asi zvakadini nezvinobatanidza? Sisitimu yakasimba chete sechikamu chayo chisina kusimba, uye kusabatana kwayo kunogona kukonzera kutadza kukuru.

Zvishandiso zvePolypropylene zvinoongororwawo uchishandisa PN system, inowanzo kuve PN10 kana PN16. Kune system yakavimbika, chiyero chekumanikidzwa kwezvishandiso zvako nemapaipi chinofanira kunge chakaenzana kana kupfuura chiyero chemavharuvhu ako.

Vharuvhu yebhora inogona kubata psi yakawanda sei?

Unongoda mhinduro iri nyore muPSI, asi zvinodiwa zvinowanzova mu "bar" kana "PN". Kuita shanduko nekukurumidza mumusoro mako kune njodzi kana kuchengetedzeka uye kunaka kwemidziyo kuri panjodzi.

Izvi zvinosiyana zvikuru, kubva pa150 PSI kune mamwe mavharuvhu epurasitiki kusvika pa10,000 PSI kune mavharuvhu esimbi ane simba repamusoro. Kuti uwane PSI, shandura kubva paPN rating: 1 bar inenge 14.5 PSI.

Hapana mhinduro imwe chete kumubvunzo uyu, ndosaka zvichikosha kutarisa vharuvhu chaiyo yauri kushandisa. Zvinhu zvacho (PP, PVC, Brass, Stainless Steel), saizi, uye dhizaini zvese zvinoshandura mhinduro. Zvisinei, tinogona kuzviita zviri nyore kune zvigadzirwa zvedu. Pntek yeduMavharuvhu ebhora ePPvakaongororwa PN16. Kuchinja kuri nyore, uye munhu wese ari muchikwata chako anofanira kuzviziva: ingowedzera kukosha kwebhaa ne14.5. Saka, chiyero chePN16 chinoreva kuti vharuvhu inogona kubata 16 bar yekumanikidzwa. Kuti uwane PSI, unoverenga: 16 bar x 14.5 PSI/bhaa = 232 PSI. Tinowanzo tenderedza izvi ku235 PSIkuti uwane nhamba yakajeka uye yakachengeteka. Iyi ndiyo chiyero pakupisa kwekunze. Kana mutengi wako muKuala Lumpur ari kuyerera mvura pa60°C (140°F) kuburikidza nemutsetse, chiyero ichocho che235 PSI hachichashandi. Kumanikidzwa kwakachengeteka kuchava kwakaderera zvakanyanya, sezvakaratidzwa pakukoromoka kunonyadzisa.
