Wakaisa vharuvhu itsva, uchitarisira chisimbiso chakanaka. Kudonhedza mvura zvishoma nezvishoma, kusinganzwiki kunogona kukonzera kukuvara kwemvura izvozvi, usingazive uye kukanganisa kushanda kwako nesimba.

Vharuvhu yePVC yemhando yepamusoro haifanirwe kudonha. Kudonha kunowanzoitika nekuda kwekusaiswa zvakanaka, kukuvara kwemuviri, kana kukwegura zvakanyanya, kwete nekuda kwekusagadzikana kwekugadzirwa kwevharuvhu yakagadzirwa zvakanaka.

Iyi inyaya inokosha yekuvimbana pakati pemugadziri nenyanzvi. Pandinokurukura nezvemhando yezvigadzirwa zvedu nevatinoshanda navo vakaita saBudi muIndonesia, iyi inyaya yatinokurukura zvakadzama. Vatengi vake, makondirakiti nevavaki, vanovimba kuti zvinhu zvavanoisa hazvina chikanganiso. Kudonhedza kamwe chete kunogona kukanganisa mukurumbira wavo. Saka, zvakakosha kunzwisisa kuti vharuvhu pachayo yakagadzirirwa kuti ivehaibvisi mvuraChinangwa chikuru chinofanira kunge chiri pazvinhu zvinowanzokonzera kudonha kwemvura mumunda, izvo zvinogona kudzivirirwa nguva dzose.

Mavharuvhu ebhora rePVC anogona kubuda here?

Wanamira vharuvhu yePVC uye basa racho rapera. Asi kakukanganisika kadiki kanogona kukonzera kubuda kwemvura gare gare, zvichiita kuti ugadzirise zvinonetsa uye zvinodhura.

Ehe, dzinogona kudonha. Nzvimbo dzinonyanya kudonha mvura haisi yemukati mevharuvhu asi yekunze—ingava majoini e solvent asina kunamirwa zvakanaka kana kuti ma threaded connections asina kuvharwa zvakanaka, kwete muviri wevharuvhu pachawo.

Kunyangwe vharuvhu yakanakisa pasi rose inodonhedza mvura kana isina kuiswa nemazvo. Kunzwisisa kuti mvura inodonhedza mvura inoitika kupi ndiyo nhanho yekutanga yekudzivirira. Mukuona kwangu, pane nzvimbo nhatu huru dzinogona kubuda mvura.

1. Kubuda kwemvura paConnections(Yakajairika)

Apa ndipo panoitika kudonha kwemvura kunopfuura 90%.

• Majoini Akasungirirwa Nezvinyungudutsa:Kudonha kwemvura pano kunoreva kuti weld yemakemikari yakanga isina kukwana. Izvi zvinogona kuitika kana simende isina kukwana yakashandiswa, pombi isina kuiswa zvizere musokisi yevharuvhu, kana kuti kutenderedzwa kwakakosha kwekota isina kuitwa kuti simende iparadzirwe zvakaenzana.
• Kubatana Kwakabatana:Kubuda kwemvura pamisungo ine shinda kunowanzokonzerwa nekusashandisa tepi yakakwana yePTFE thread seal kana kuishandisa zvisirizvo. Kusunga zvakanyanya chimwe chikonzero chikuru; zvinogona kukonzera kuputika kudiki muchikamu chemukadzi, zvichiita kuti mvura idonhe zvishoma nezvishoma.

2. Kudonhedza Mvura Kubva Mubato

Izvi hazviwanzoitiki, kunyanya pamavharuvhu matsva. Mukati mevharuvhu, tsinde rinobatanidza pamubato rinovharwa neringi rimwe chete kana akawanda eEPDM O-rings. Kana kudonha kukaonekwa pasi pemubato, zvinoreva kuti chisimbiso ichi chakanganiswa. Pavharuvhu chaiyo yemubatanidzwa, dzimwe nguva unogona kusimbisa nati yekurongedza kuti udzvinyirire chisimbiso ichi uye umise kudonha. Pavharuvhu yakamanikana, izvi zvinowanzoda kutsiviwa.

3. Kubuda Kwemvura Muvharuvhu (Yemukati)

Iyi ndiyo mhando isingawanzoitiki yekudonha kwemvura pavharuvhu yemhando yepamusoro. Izvi zvinoreva kuti vharuvhu iri kudonha mvura kana yakavharwa. Izvi zvinowanzoitika nekuti marara akaita sedombo diki kana jecha anobatwa mukati, zvichidzivirira bhora kuti risavhare zvakakwana pachigaro chePTFE.

Mavharuvhu ebhora ePVC akavimbika zvakadii?

Unoda vharuvhu yaunogona kuisa uye kuvimba nayo kwemakore. Kusarudza vharuvhu yakachipa, isina kuongororwa kunogona kutungamira mukudzoserwa kwesimba, zvichikanganisa mukurumbira wako uye purofiti pabasa.

Mavharuvhu ebhora ePVC emhando yepamusoro akavimbika zvikuru nekuda kwekugadzirwa kwawo kuri nyore uye zvikamu zvishoma zvinofamba. Kuvimbika kwawo kunoenderana zvachose nemhando yezvinhu zvinoshandiswa uye kugadzirwa kwakanyatsogadzirwa.

Kupenya kuri nyore kwevharuvhu yebhorandizvo zvinoita kuti ive yakavimbika. Dhizaini yacho yakanaka kwazvo: bhora rine gomba rinotenderera madhigirii makumi mapfumbamwe kusvika panzvimbo yakavhurika kana yakavharwa. Pane zvinhu zvishoma zvinogona kukanganisa. Zvisinei, haasi mavharuvhu ese ePVC akagadzirwa zvakaenzana. Musiyano uripo pakati pevharuvhu yakavimbika neisingavimbike unobva pakunaka kwezvinhu zvakagadzirwa uye maitiro ekugadzira. Ichi chinhu chatinonyanya kukoshesa kuPntek. Vharuvhu yakachipa inogona kutaridzika zvakafanana kunze, asi zviri mukati ndizvo zvinonyanya kukosha.

Vharuvhu yakavimbika inzira yekuisa rugare rwepfungwa.

Vharuvhu yebhora yePVC inogara kwenguva yakareba sei?

Unofanira kuziva nguva yekushanda kwezvikamu zvaunoisa. Asi mavharuvhu haana zuva rakajeka rekupera, zvichiita kuti kuronga kwenguva refu kuve kwakaoma uye zvichiita kuti vatengi vasazive nezvematambudziko emangwana.

Vharuvhu yebhora yePVC yakagadzirwa zvakanaka, inoshandiswa mumamiriro ezvinhu akakodzera, inogona kugara kwemakore gumi kusvika makumi maviri nemashanu kana kupfuura. Nguva yehupenyu inonyanya kukanganiswa nemwaranzi yeUV, tembiricha, kusangana nemakemikari, uye kuti inoshandiswa kangani.

Hapana zuva rakatarwa rekupera kwevharuvhu yePVC nekuti hupenyu hwayo hunoenderana zvakanyanya nenzvimbo yayo uye mashandisirwo ayo. Vharuvhu yakaiswa mukati meimba pamutsetse wemvura inotonhora inoshandiswa kashoma pagore inogona kugara kwemakumi emakore. Vharuvhu yakaiswa panze pamutsetse wemvura inopisa inoshanda zuva nezuva ichave nehupenyu hupfupi. Kunzwisisa zvinhu zvinopfupisa hupenyu hwevharuvhu ndicho chinhu chikuru pakuwedzera hupenyu hwayo.

• Kuonekwa neUV:Uyu ndiye muvengi mukuru wePVC.Zuva rezuva rinoita kuti PVC iome nekufamba kwenguvaChero vharuvhu yakaiswa panze inofanira kudzivirirwa kubva kuzuva, kungave nekuiputira kana kuipenda nependi yelatex inobva mumvura.
• Kupisa Kwakakwirira: PVC inonyorova painopisa, izvo zvinoderedza kumanikidzwa kwayo. Vharuvhu inogara ichiiswa mumvura inopisa (pedyo nemuganhu wayo wepamusoro we140°F / 60°C) iri pasi pekumanikidzwa kwakanyanya uye ichakurumidza kukura.
• Makemikoro:Kunyange zvazvo PVC isingakuvadzi makemikari akawanda, zvinhu zvinokakavara zvinogona kurwisa mapurasitiki kanaZvisimbiso zveEPDM/FKMGara uchitarisa akuenderana kwemakemikarichati kana vharuvhu ichashandiswa kune chimwe chinhu chisiri mvura.
• Kushandiswa Kwakawanda:Vharuvhu chishandiso chemuchina. Kana ikatenderedzwa zvakanyanya, zvigaro nezvisimbiso zvinopera zvakanyanya. Pakushandisa ma "high-cycle", zvakakosha kusarudza vharuvhu yakagadzirirwa izvozvo.

Nzira yekumisa sei vharuvhu yebhora kuti isadonhe?

Waona donhwe rinotyisa kubva pakubatanidza vharuvhu. Pfungwa yako yekutanga ndeyekugadzirisa kwakaoma, kubvisa pombi uye kutambisa maawa akawanda enguva yako nesimba rako.

Kana paine maburi ari pamubato, edza kusimbisa mayunion nuts kana packing nut. Kana paine maburi ari mushinda, unofanira kuvharira tambo zvakare. Kana paine maburi ari mushinda, vharuvhu inofanira kuchekwa yotsiviwa.

Kugadzirisa mvura inodonha kunoenderana nekuti mvura iri kubva kupi. Danho rekutanga kudzima mvura uye kusunungura chero kumanikidzwa kuri mumutsara.

Kugadzirisa Kubuda Kwemvura Mubato

Kudonha uku kunoonekwa sedonhwe chaipo panopindwa nemubato wevharuvhu. PaPntek yedumavharuvhu emubatanidzwa wechokwadi, izvi zvinowanzogadziriswa. Unogona kusunungura ma union nuts makuru ari kumativi ese emuviri wevharuvhu. Izvi zvinokutendera kuti usimudze vharuvhu kubva mupombi. Pamusoro pepakati apa, pane nati hombe yakatenderedza tsinde. Kusimbisa nati iyi zvinyoro nyoro (inonzi carrier kana packing nut) kunogona kudzvanya maO-rings uye kumisa kubuda kwemvura. Pamavharuvhu akamanikana, ane chidimbu chimwe chete, izvi hazvigoneke uye vharuvhu inofanira kutsiviwa.

Kugadzirisa Kubuda Kwemvura Kubva Pakubatanidza Kwakabatana

Uku kudonha kwemvura kunogona kugadziriswa asi kunonetsa. Unofanira kubvisa tambo yevharuvhu zvachose kubva panzvimbo yaisungirirwa. Chenesa zvakanaka tepi yese yekare yekuvhara tambo kana kunamira kubva patambo dzese dzechirume nedzechikadzi. Wobva waisa zvakare itsva, yepamusoro-soro.Tepi yePTFE(3-4 wraps in direction ye threads). Unganidzazve joinhi, uchiisimbisa zvakasimba asi uchichenjerera kuti usanyanya kuomesa wobva watsemura fitting.

Kugadzirisa Kubuda Kwemvura Kubva Mujoini Yekunyungudutsa (Yakabatanidzwa)

Uku ndiko kudonha kwemvura kwausingakwanise kugadzirisa. Hapana chigadzirwa kana nzira inogona kugadzirisa kudonha kwemvura nenzira yakavimbika.joini rakasungirirwa zvine solventMhinduro chete yehunyanzvi uye inogara iripo ndeyekucheka vharuvhu kubva papombi woisa imwe itsva. Ndosaka zvichikosha kuti unamate zvakanaka kekutanga.
