Unovimba neVharuvhu yebhora yePVCkana paine dambudziko guru rekudzima magetsi, asi rimwe zuva mvura inodonha kana kupwanyika. Iye zvino chirongwa chako chamira, mutengi wako haasi kufara, uye unofanira kusangana nematambudziko emvura anodhura uye kugadzirisa.

Mavharuvhu ebhora ePVC anowanzo kundikana nekuda kwezvikonzero zvishanu zvikuru: kusimba zvakanyanya panguva yekuisa, kukwegura kana kuti zvisimbiso zvakasakara, kushandisa tambo dzisina kuenzana seNPT vs BSPT, kuisa vharuvhu patembiricha iri pamusoro pemuganhu wayo, uye kuputika kwemuviri nekuda kwekunetseka.

Pandinotaura nemumwe wangu Budi, tinowanzo kurukura nezvematambudziko anosangana nevatengi vake mumunda. Vharuvhu inodonhedza mvura inogona kuita sedambudziko diki, asi inogona kuva chiratidzo chedambudziko guru mukugadzirwa kwesystem kana maitiro ekuisa. Kunzwisisa kuti sei vharuvhu ikakundikana ndiyo kiyi yekudzivirira kuti isadzokorore. Hazvisi zvekungotsiva chikamu chakatyoka; ndezvekuvaka masisitimu akavimbika kwenguva refu. Ngatitarisei zvikonzero zvinowanzoita kuti vharuvhu yebhora yePVC ikuodze mwoyo.

Ndezvipi zvinetso zvinowanzo sangana nemavharuvhu ebhora ePVC?

Unoedza kusimbisa chinobatanidza vharuvhu yako itsva, wobva wanzwa kutsemuka kushoma. Vharuvhu yava nekakupwanyika kebvudzi pachiteshi, zvichiita kuti isashande zvachose isati yatomboiswa.

Matambudziko anowanzoitika mumuviri inyaya dzekutsemuka kwezvibato nekuda kwekusimba zvakanyanya, mibato yakatyoka nekuda kwekushandisa simba rakawanda, uye kubuda kwemvura kubva pamudzi. Izvi zvinowanzokonzerwa nematekiniki asina kunaka ekuisa panzvimbo pevharuvhu isina kunaka.

Iyi ndiyo kutadza kunowanzoitika uye kunonetsa kwandinonzwa nezvako. Muviri wevharuvhu yePVC wakasimba, asi uchiri wepurasitiki. Paunoedza kusimbisa pombi yesimbi yakarukwa kana kuisa mushinda yePVC yechikadzi, zviri nyore kushandisa simba rakawandisa. Shinda dzesimbi dzakapinza dzinoshanda sewedge, dzichiisa kumanikidzwa kukuru kwekunze pavharuvhu. Izvi zvinotungamira pakutsemuka kunotanga pachiteshi. Zano rangu nderekuti utange wasimbisa nemaoko, wobva washandisa chipanera kwekamwe chete kana kaviri chete. Chisimbiso chinogadzirwa nechisimbiso cheshinda, kwete nesimba guru. Kusimbisa vharuvhu zvakanyanya hakuiti kuti pave nechisimbiso chiri nani; kunongogadzira vharuvhu yakatyoka.

Chikonzero & Dziviriro: Kukuvara Kwemuviri

Chii chinoita kuti vharuvhu yePVC ikundikane nekufamba kwenguva?

Sisitimu yako yave ichishanda zvakanaka kwemakore, asi ikozvino vharuvhu yatanga kudonhedza mvura zvishoma nezvishoma kubva pamubato. Kudonhedza kwacho kudiki, asi zvinoratidza kuti vharuvhu yave kutanga kukundikana kubva mukati.

Nekufamba kwenguva, zvisimbiso zvinochinjika zviri mukati mevharuvhu ndizvo zvinogona kukanganisa. EPDM kana NBR O-rings dziri padanda uye zvigaro zvePTFE zvakatenderedza bhora zvinogona kuoma, kutetepa, kana kutsemuka nekukura.

Vharuvhu yega yega ine seti yezvisimbiso zvemukati zvinoita basa chairo. Zviviri zvidikiMhete dzeOkutenderedza tsinde yevharuvhu kunodzivirira mvura kuti isabude ichitenderedza mubato. Zvigaro zviviri zvakakura, zvakaita sedenderedzwa zvinogadzira chisimbiso chakatenderedza bhora pacharo kana vharuvhu yavharwa. Zvisimbiso izvi zvinowanzogadzirwa nezvinhu zvakaita seRabha yeEPDMkana kuti PTFE. Kunyange zvazvo dzakasimba zvikuru, hadzigari kwenguva refu. Kugara dzichishandiswa mumakemikoro mumvura, senge chlorine, kunogona kuita kuti dziome uye dziome. Mwenje weUV unobva kuzuva unogonawo kudzikanganisa. Mumakore akawanda ekuvhurwa nekuvhara, dzinogonawo kupera simba. Ichi chikamu chehupenyu hwevharuvhu. Pakushandisa kwakakosha, itsika yakanaka kuronga kutsiviwa kwemavharuvhu sechikamu chekugadzirisa kwenguva refu.

Chii chinokonzera kutadza kushanda kwevharuvhu yebhora panguva yekuiswa?

Wabatanidza mapaipi ako ese, asi chimwe chete chine mvura inobuda zvakanyanya. Wakashandisa tepi yakawanda yeshinda, asi mvura ichiri kuwana nzira yekubuda nayo, ichidonha nguva dzose kubva mushinda.

Chikanganiso chinowanzoitika pakuisa chinhu chinokonzera kutadza kushanda nekukurumidza ndechekusawirirana kweshinda. Kuedza kubatanidza NPT thread fitting neBSPT valve (kana kuti zvinopesana) kuchaita kuti pave nechinhu chisina kunaka chinovimbisa kuti chichabuda mvura.

Sezvatakakurukura naBudi nezvemusika weIndonesia, unowanzoona zvese zviri zviviriNPT uye BSPT zviyero. Dzinotaridzika zvakafanana, asi hadzienderane. NPT threads dzine angle ye60-degree, nepo BSPT threads dzine angle ye55-degree. Kana ukaedza kudzibatanidza, dzinoyambuka thread dzosungana. Hausi kugadzira chisimbiso chakakodzera; uri kungokuvadza threads pamativi ese ari maviri. Hapana huwandu hwe thread sealant hunogona kugadzirisa kusawirirana uku kukuru. Mvura inogara ichiwana nzira kuburikidza nepakati pemaburi. Usati waisa chero chinhu, unofanirwa kusimbisa kuti thread yemurume neyemukadzi zvakafanana. Kuongorora uku kunogona kudzivirira chimwe chezvikonzero zvakajairika uye zvinogoneka kudzivirirwa zvekubuda kwemvura. Ichi chinhu chidiki chinoita mutsauko mukuru.

Chii chinonyanya kukonzera kutadza kushanda kwevharuvhu?

Vharuvhu inongoerekana yakombama yotanga kudonha zvakanyanya, kunyangwe yakaiswa nemazvo. Kumanikidzwa kwesystem kwakajairika, uye hapana kukuvara kunooneka, zvichikusiya uchivhiringidzika nezvechikonzero chekukundikana kamwe kamwe.

Chinhu chimwe chete chinonyanya kukonzera kutadza kushanda zvakanaka kwevharuvhu yePVC ndechekupfuura tembiricha yakatarwa. Kushandisa vharuvhu yebhora yePVC yakajairwa mumutsara wemvura inopisa kuchaita kuti ipfave, ikanganise chimiro, uye ikurumidze kukundikana.

Iyi inyaya yakakosha yekuchengetedza. PVC yakajairika chinhu chakanaka kwazvo, asi ine muganho wakajeka: kupisa. Haifanirwe kushandiswa mukushandiswa uko tembiricha ichapfuura 60°C (140°F). Pamusoro petembiricha iyi, chinhu chinotanga kupfava senge chizi chakaoma chinosara muzuva. Vharuvhu yakayerwa 16 bar yekumanikidzwa patembiricha yemumba ingangokwanisa kubata chidimbu cheizvozvo isati yatanga kuora. Bhora remukati rinogona kutsauka kubva muchimiro charo chakatenderera, uye muviri wevharuvhu unogona kuzvimba. Kana izvi zvaitika, zvisimbiso hazvichagoni kubata nemazvo, zvichikonzera kudonha kukuru. Kana kushandisa kwako kuchisanganisira mvura inopisa, unofanirwa kushandisa chinhu chakagadzirirwa icho, sengeCPVC. Iri harisi zano; mutemo wehurongwa hwakachengeteka uye hwakavimbika.

Mhedziso

Dzivirira kutadza kwevharuvhu yePVC nekusunga nemazvo, kufananidza shinda (NPT/BSPT), kutevedzera muganho wekupisa we60°C, uye kuronga kukwegura kwechisimbiso. Kuisa nekushandisa nemazvo ndizvo zvakakosha kuti sisitimu igare kwenguva refu uye isingadonhe mvura.
