Ndi kuwongolera kwa moyo wa anthu, kuzindikira zachitetezo cha chilengedwe komanso nkhawa za thanzi, kusintha kobiriwira kwamakampani opanga zida zomangira kwayambika pankhani yopereka madzi ndi ngalande. Malinga ndi kuchuluka kwa zowunikira zamadzimadzi, mapaipi azitsulo ozizira amakhala dzimbiri pakadutsa zaka zosakwana 5, ndipo kununkhira kwachitsulo kumakhala koopsa. Anthu okhala m’derali amadandaula m’madipatimenti a boma motsatizanatsatizana, zomwe zinayambitsa vuto la anthu. Poyerekeza ndi mipope chikhalidwe zitsulo, mapaipi pulasitiki ndi makhalidwe a kulemera kuwala, kukana dzimbiri, mkulu compressive mphamvu, ukhondo ndi chitetezo, kukana madzi otsika, kupulumutsa mphamvu, kupulumutsa zitsulo, bwino malo okhala, moyo wautali utumiki, ndi unsembe yabwino. Wokondedwa ndi gulu la uinjiniya ndipo ali ndi udindo wofunikira kwambiri, ndikupanga chitukuko chopanda nzeru.

Makhalidwe ndi kugwiritsa ntchito chitoliro cha pulasitiki

﹝一﹞Polypropylene chitoliro (PPR)

(1) M'ntchito zamakono zomanga ndi kukhazikitsa, zambiri zotenthetsera ndi madzi ndi mapaipi a PPR (zidutswa). Ubwino wake ndi wosavuta komanso wofulumira kukhazikitsa, wokonda zachuma komanso wokonda zachilengedwe, wopepuka, waukhondo komanso wopanda poizoni, kukana kutentha kwabwino, kukana dzimbiri, ntchito yabwino yosungira kutentha, moyo wautali ndi zabwino zina. The m'mimba mwake chitoliro ndi kukula chimodzi chachikulu kuposa awiri mwadzina, ndi diameters chitoliro makamaka anawagawa DN20, DN25, DN32, DN40, DN50, DN63, DN75, DN90, DN110. Pali mitundu yambiri ya zoyikira mapaipi, ma tee, zigongono, zotsekera mapaipi, zochepetsera, zomangira mapaipi, zingwe za mapaipi, mabulaketi, zopachika. Pali mapaipi amadzi ozizira ndi otentha, chitoliro cha madzi ozizira ndi chubu chobiriwira, ndipo chitoliro cha madzi otentha ndi chubu chofiira. Ma valves amaphatikizapo ma valve a PPR a mpira, ma valve a globe, ma valve a butterfly, ma valve a zipata, ndi omwe ali ndi PPR ndi mkuwa mkati mwake.

(2) Njira kugwirizana chitoliro monga kuwotcherera, otentha Sungunulani ndi ulusi kugwirizana. Chitoliro cha PPR chimagwiritsa ntchito cholumikizira chosungunuka chotentha kuti chikhale chodalirika kwambiri, chosavuta kugwiritsa ntchito, kulimba kwa mpweya wabwino, komanso kulimba kwa mawonekedwe apamwamba. Kulumikizana kwa chitoliro kumagwiritsa ntchito cholumikizira chogwirizira pamanja cholumikizira kutentha-kusungunuka. Musanayambe kulumikiza, chotsani fumbi ndi zinthu zakunja kuchokera ku mapaipi ndi zowonjezera. Pamene kuwala kofiira kwa makina kumayatsa ndi kukhazikika, gwirizanitsani mapaipi (zidutswa) kuti zilumikizidwe. DN<50, kuya kwa kusungunula kotentha ndi 1-2MM, ndi DN<110, kuya kwa kutentha ndi 2-4MM. Mukalumikiza, ikani kumapeto kwa chitoliro popanda kuzungulira Lowetsani mu jekete yotenthetsera kuti mufikire kuya komwe kudakonzedweratu. Pa nthawi yomweyi, kanikizani zoyikapo za chitoliro pamutu wotenthetsera popanda kuzungulira kuti muwotche. Pambuyo pa nthawi yotentha, chotsani nthawi yomweyo mipope ndi zida zopangira zitoliro kuchokera ku jekete yotenthetsera ndi mutu wotentha panthawi imodzimodziyo, ndikuyiyika pakuya kofunikira mofulumira komanso mofanana popanda kuzungulira. Flange yunifolomu imapangidwa pamgwirizano. Panthawi yotentha yomwe yatchulidwa, cholumikizira chatsopanocho chimatha kusinthidwa, koma kuzungulira ndikoletsedwa. Mukatenthetsa mapaipi ndi zopangira, pewani kutentha kwambiri ndikupangitsa kuti makulidwe ake akhale ochepa. Chitolirocho ndi chopunduka mu chitoliro choyenera. Ndizoletsedwa kutembenuza nthawi yotentha yosungunula intubation ndi calibration. Sipayenera kukhala lawi lotseguka pamalo opangira opaleshoni, ndipo ndizoletsedwa kuphika chitoliro ndi lawi lotseguka. Mukalumikiza chitoliro chotenthetsera ndi zolumikizira molunjika, gwiritsani ntchito mphamvu yopepuka kuti chigongono chisapindike. Kulumikiza kumalizidwa, mapaipi ndi zopangira ziyenera kugwiridwa mwamphamvu kuti zikhalebe ndi nthawi yokwanira yozizirira, ndipo manja amatha kumasulidwa pambuyo pozizira kwambiri. Pamene chitoliro cha PP-R chikugwirizana ndi chitoliro chachitsulo, chitoliro cha PP-R chokhala ndi zitsulo chiyenera kugwiritsidwa ntchito ngati kusintha. Kuyika kwa chitoliro ndi chitoliro cha PP-R zimalumikizidwa ndi socket yosungunuka yotentha ndikulumikizidwa ndi chitoliro chachitsulo kapena zida za hardware za ukhondo. Mukamagwiritsa ntchito ulusi wolumikizira, ndikofunikira kugwiritsa ntchito tepi ya polypropylene yaiwisi ngati chosindikizira. Ngati faucet yolumikizidwa ndi dziwe la mop, ikani chigongono chachikazi (chopangidwa mkati) kumapeto kwa chitoliro cha PPR pamenepo. Osagwiritsa ntchito mphamvu mopitilira muyeso pakuyika mapaipi, kuti musawononge zomangira za ulusi ndikuyambitsa kutayikira pakulumikizana. Kudula chitoliro kungathenso kudulidwa ndi mapaipi apadera: bayonet ya lumo la chitoliro liyenera kusinthidwa kuti lifanane ndi m'mimba mwake ya chitoliro chomwe chikudulidwa, ndipo mphamvu iyenera kugwiritsidwa ntchito mofanana pozungulira ndi kudula. Pambuyo podula, fracture iyenera kuzunguliridwa ndi chozungulira chofananira. Pamene chitoliro chathyoledwa, gawolo liyenera kukhala lolunjika ku chitoliro cha chitoliro popanda burrs.

﹝二﹞ Rigid Polyvinyl Chloride Pipe (UPVC)

(1) mapaipi a UPVC (zidutswa) amagwiritsidwa ntchito ngati ngalande. Chifukwa cha kulemera kwake, kukana kwa dzimbiri, mphamvu zambiri, ndi zina zotero, zimagwiritsidwa ntchito kwambiri poika mapaipi. Nthawi zambiri, moyo wautumiki nthawi zambiri umakhala zaka 30 mpaka 50. Chitoliro cha UPVC chili ndi khoma losalala lamkati komanso kukana kwamadzimadzi otsika, komwe kumapambana chilema chomwe chitoliro chachitsulo chimakhudza kuthamanga chifukwa cha dzimbiri ndi makulitsidwe. The m'mimba mwake chitoliro ndi chimodzi kukula kuposa awiri mwadzina.Zopangira mapaipiamagawidwa kukhala ma oblique tee, mitanda, zigongono, zitoliro zitoliro, zochepetsera, zomangira mapaipi, misampha, zitoliro za mapaipi, ndi zopachika.

(2) Chotsani guluu kuti mulumikizane. Zomatira ziyenera kugwedezeka musanagwiritse ntchito. Mapaipi ndi zitsulo zazitsulo ziyenera kutsukidwa. Pang'ono pang'ono kusiyana kwa socket, ndibwino. Gwiritsani ntchito nsalu ya emery kapena tsamba la saw kuti muwononge malo olowa. Tsukani guluuyo pang'onopang'ono mkati mwa soketi ndikuyika guluu kawiri kunja kwa soketi. Dikirani kuti guluu liume kwa 40-60s. Mukayiyika m'malo mwake, iyenera kuperekedwa kuti muwonjezere kapena kuchepetsa nthawi yowumitsa guluu malinga ndi kusintha kwa nyengo. Madzi ndi oletsedwa kwambiri panthawi ya mgwirizano. Chitolirocho chiyenera kuikidwa chathyathyathya mu ngalandeyo chitatha. Mgwirizanowu ukauma, yambani kubwezeretsanso. Mukabwezeretsanso, lembani kuzungulira kwa chitoliro mwamphamvu ndi mchenga ndikusiya gawo lolumikizana kuti libwezeretsedwe mochuluka. Gwiritsani ntchito mankhwala ochokera kwa wopanga yemweyo. Mukalumikiza chitoliro cha UPVC ku chitoliro chachitsulo, chophatikizira cha chitoliro chachitsulo chiyenera kutsukidwa ndi kumatidwa, chitoliro cha UPVC chimatenthedwa kuti chifewetse (koma osawotchedwa), ndiyeno chimayikidwa pa chitoliro chachitsulo ndikukhazikika. Ndi bwino kuwonjezera chitoliro chochepetsa. Ngati chitoliro chawonongeka m'dera lalikulu ndipo chiyenera kusintha chitoliro chonse, cholumikizira chazitsulo ziwiri chingagwiritsidwe ntchito m'malo mwa chitoliro. Njira yosungunulira ingagwiritsidwe ntchito kuthana ndi kutayikira kwa zosungunulira zomangira. Panthawi imeneyi, kukhetsa madzi mu chitoliro choyamba, ndi kupanga chitoliro kupanga zoipa kuthamanga, ndiyeno jekeseni zomatira pa pores wa kutayikira gawo. Chifukwa cha kupsinjika koyipa mu chubu, zomatirazo zimayamwa mu pores kuti zikwaniritse cholinga choletsa kutayikira. Njira yolumikizira zigamba imayang'ana makamaka pakutha kwa mabowo ang'onoang'ono ndi zolumikizira mu mapaipi. Panthawiyi, sankhani mapaipi aatali a 15-20cm amtundu womwewo, aduleni motalika, roughen pamwamba pa chitoliro ndi kunja kwa chitoliro kuti apangidwe molingana ndi njira yolumikizira mfundozo, ndikuphimba malo omwe akutuluka. ndi guluu. Njira yopangira magalasi ndikukonzekera yankho la utomoni wokhala ndi utomoni wa epoxy ndi wochiritsa. Mukathira utomoni wa utomoni ndi nsalu yagalasi, imavulazidwa mofanana pamwamba pa chitoliro kapena cholumikizira chomwe chikutuluka, ndipo chimakhala FRP pambuyo pochiritsa. Chifukwa njirayi ili ndi zomangamanga zosavuta, zosavuta kuzidziwa bwino, plugging yabwino komanso mtengo wotsika mtengo, imakhala ndi kukwezedwa kwakukulu ndikugwiritsa ntchito mtengo wotsutsa-seepage ndi kutayikira.
