Wakanamira vharuvhu yako itsva yePVC mupombi, asi ikozvino yave kudonha. Rimwe rakashata rakabatana rinoreva kuti unofanira kucheka pombi uye kutanga patsva, kutambisa nguva nemari.

Kuisa zvakanaka aPVC bhora vharafu, unofanira kushandisa PVC-chaiyo primer uyesolvent simende. Iyo nzira inosanganisira kucheka pombi yakachena, kubvisa, priming zvose zviri pamusoro, kushandisa simende, uye ipapo kusunda uye kubata chibatanidza zvakasimba kwemasekonzi 30 kugadzira zvachose kemikari weld.

Iyi nzira ndeyekugadzira kemikari chisungo chakasimba sepombi pachayo, kwete kungonamatira zvikamu pamwechete. Inyaya yakakosha yandinogara ndichisimbisa nevandinoshanda navo, saBudi, maneja wekutenga muIndonesia. Vatengi vake, kubva kumakondirakiti makuru kusvika kune vatengesi vepanzvimbo, havagone kubhadhara kukundikana. Chibatanidzwa chimwe chakashata chinogona kunyudza nguva yeprojekiti uye bhajeti. Ngatifambei mumibvunzo yakakosha kuti tive nechokwadi chekuisa kwese kwaunobata budiriro inogara kwenguva refu.

Unoisa sei vharuvhu yebhora paPVC pombi?

Iwe une zvikamu zvakanaka, asi iwe unoziva kuti hapana yechipiri mikana nePVC simende. Kukanganisa kudiki kunoreva kucheka chikamu chepombi uye kutanga kubva pakatanga.

Iyo yekuisa iyo inoshandisa sont welding uye inosanganisira matanho mashanu akakosha: kucheka pombi sikweya, kubvisa mipendero, kushandisa PVC primer kune ese ari maviri, kupfekedza nePVC simende, uyezve kusunda zvikamu pamwe chete nekota kutendeuka uye kuzvibata zvakasimba.

Kuwana maitiro aya ndiko kunoparadzanisa basa rehunyanzvi kubva kune dambudziko remangwana. Ngatiburitse nhanho imwe neimwe zvakadzama. Iyi ndiyo nzira chaiyo yandinopa kune vatengi veBudi kuvimbisa chisimbiso chakakwana.

1. Cheka & Deburr:Tanga neakachena, square cut papombi yako. Chero kona inogona kugadzira gap mujoinhi. Mushure mekucheka, shandisa mudziyo wekubvisa kana banga nyore kugera chero fuzz yepurasitiki kubva mukati nekunze kwemupendero wepombi. Aya mabhura anogona kukwenya simende kure uye kudzivirira pombi kuti isagara zvizere.
2. Prime:Isa jasi rakasununguka rePVC yekutanga(inowanzova yepepuru) kune kunze kwepombi uye mukati mesoketi yevharuvhu. Usasvetuka danho iri! Primer haisi yekuchenesa chete; inotanga kupfavisa purasitiki, ichigadzirira iyo kemikari weld.
3. Simende:Nepo iyo primer ichiri kunyorova, shandisa iyo kunyange layer yePVC simendepamusoro penzvimbo dzakakwirira. Isa papombi kutanga, wozopa soketi yevharuvhu jasi rakatetepa.
4. Sunda, Tendeuka & Bata:Pakarepo sunda pombi muchisokisi nediki kota-turn twist. Iyi twist inobatsira kuparadzira simenti zvakafanana. Unofanira ipapo kubata joint pamwe zvakasimba kwemasekonzi makumi matatu. Iyo kemikari inokonzeresa inoburitsa kumanikidza kunoedza kusundira pombi kuti idzokere kunze.

Ndeipi nzira yakarurama yekuisa vheji yebhora?

Ivhavha iri mukati, asi mubato unorovera kumadziro. Kana kuti zvakatoipisisa, iwe wakaisa yechokwadi yevhavhavha yekubatana padyo neimwe yakakodzera zvekuti haugone kuwana wrench panzungu.

Iyo "nzira yakarurama" yekuisa vheji yebhora inofunga nezvekushandiswa kweramangwana. Izvi zvinoreva kuve nechokwadi chekuti mubato une yakazara 90-degree clearance kuti itendeuke uye kuti nzungu dzemubatanidzwa pavharuvhu yemubatanidzwa inosvikirika zvakakwana kuitira kuchengetedza ramangwana.

Kuiswa kwakabudirira kunopfuura kungopfuura aleak-proof chisimbiso; ndezvekushanda kwenguva refu. Apa ndipo apo kuronga kudiki kunoita musiyano mukuru. Chikanganiso chakanyanya chandinoona kushaikwa kwekuronga kuwana. Ivhavhavha yebhora inofanirwa kutenderera 90 madhigirii kuti ibve kubva yakazaruka kusvika yakavharwa zvakazara. Usati watombovhura gaba resimende, bata vharuvhu panzvimbo uye zunza mubato kuburikidza nekufamba kwayo kwakazara. Ita shuwa kuti hairove madziro, imwe pombi, kana chimwe chinhu. Pfungwa yechipiri, kunyanya yePntek yeduchokwadi mubatanidzwa mavharuvhu, ndiko kuwana mubatanidzwa. Rubatsiro rwese rwechokwadi chemubatanidzwa dhizaini ndechekuti iwe unogona kusunungura mibatanidzwa uye kusimudza mutumbi mukuru kunze kuti ugadziriswe kana kutsiva pasina kucheka pombi. Ndinogara ndichiyeuchidza Budi kuti asimbise izvi kune vatengi vake vekontrakta. Kana iwe ukaisa vharafu kwausingakwanise kuwana wrench pane idzo nzungu, iwe uchangobva kushandura premium, serviceable valve kuita mwero, yekurasa imwe.

Ungabatanidza sei vharuvhu kune pombi yePVC?

Vhuru yako ine shinda, asi pombi yako yakatsetseka. Uri kushamisika kana uchifanira kuinamatira, kuisunga, kana imwe nzira iri nani pane imwe yekubatanidza kwakasimba.

Pane nzira mbiri dzekutanga: solvent welding (gluing) yechigarire, yakasanganiswa bond, uye yakarukwa yekubatanidza yejoini inogona kudimburwa. Kune PVC-to-PVC masisitimu, solvent welding ndiyo yakasimba uye yakajairika nzira.

Kusarudza mhando yekubatanidza yakakodzera kwakakosha. Iyo yakawanda yakawanda yePVC masisitimu anovimba nayosolvent welding, uye nokuda kwechikonzero chakanaka. Haingobatanidzi zvikamu pamwechete; inoasanganisa nemakemikari kuita chidimbu chimwe chete, chisina musono chepurasitiki chakasimba zvisingaite uye chisingabvire. Kubatanidzwa kweThread kune nzvimbo yavo, asi vanewo hutera. Izvo zvinobatsira pakubatanidza PVC valve kune pombi yesimbi kana tangi yatova netambo. Nekudaro, machira epurasitiki akabatanidzwa anogona kuve sosi yekuvuza kana isina kunamwa nemazvo neTeflon tepi kana kunamira. Zvinotonyanya kukosha, kuomesa-kusimbisa purasitiki yakasungwa ikanganiso yakajairika inogona kutsemura kubatana kwechikadzi, zvichikonzera kukundikana.

PVC bhora mavharuvhu akananga here?

Simende yakagadzirira, asi unozeza, uchitsvaga museve pamutumbi wevharuvhu. Kuisa vharafu inotungamira kumashure kungave kukanganisa kunodhura, kukumanikidza kuiparadza.

Kwete, yakajairwa PVC bhora vharafu iri bi-directional uye inovhara kuyerera zvakaenzana kubva kune chero nzira. Basa rayo harina kutsamira pakuyerera kwekufamba. Iyo chete "gwara" iro rakakosha kuriisa kuti iwe ugone kuwana mubato uye nzungu dzemubatanidzwa.

Uyu mubvunzo mukuru unoratidza kunyatsofunga. Wakarurama kuti ungwarire, sezvo mamwe mavharuvhu ari kunanga zvachose. Acheki vharafu, semuenzaniso, inobvumira chete kuyerera munzira imwe uye ichava nemuseve wakajeka wakadhindwa pairi. Kana ikaiswa kumashure, haishande. Zvisinei, ayebhora vharafudhizaini ine symmetrical. Ine bhora rine buri mukati maro rinonamira chigaro. Sezvo kune chigaro kumativi ose ari kumusoro uye pasi pemvura, valve inovhara zvakakwana pasinei nokuti mvura iri kuyerera nenzira ipi. Saka, haugone kuimisa "kumashure" maererano nekuyerera. Sezvandambotaura, iyo chete "gwara" raunoda kunetseka pamusoro paro ndiyo inoshanda yekutarisa yekushandisa valve. Unogona kushandura mubato here? Unogona kuwana mibatanidzwa here? Ndiko kuyedza kwechokwadi kwekumisikidzwa kwevhavha yemhando seyatinoburitsa paPntek.

Mhedziso

Kuti uwane yakakwana PVC bhora vharafu kuisirwa, shandisa chaiyo primer uye simende. Ronga yekubata uye yemubatanidzwa nut kuwana kuona yakavimbika, inovuza-uchapupu, uye inoshanda yekubatanidza.
