Nekuvandudzwa kwemararamiro evanhu, ruzivo rwekuchengetedzwa kwezvakatipoteredza uye zvinetso zvehutano, shanduko yakasvibira muindasitiri yezvivakwa zvekuvaka yakatangwa mumunda wekupa mvura nekudhonza. Zvinoenderana nehuwandu hukuru hwehuwandu hwemvura yekutarisa data, inotonhora-galvanized simbi pombi dzinowanzoita ngura mushure memakore asingasviki mashanu ehupenyu hwebasa, uye kunhuhwirira kwesimbi kwakakomba. Vagari vakanyunyuta kumapazi ehurumende mumwe mushure memumwe, zvichikonzera dambudziko remagariro. Kuenzaniswa nemapombi esimbi echinyakare, mapaipi epurasitiki ane huremu hwehuremu, kusimba kwemarara, simba rekumanikidza, hutsanana uye chengetedzo, kushomeka kwekuyerera kwemvura, kuchengetedza simba, kuchengetedza simbi, kuvandudzwa kwenzvimbo yekugara, hupenyu hurefu hwesevhisi, uye kuisirwa kuri nyore. Inofarirwa nenharaunda yeinjiniya uye inogara pachinzvimbo chakakosha, ichigadzira isingaite yekusimudzira maitiro.

Hunhu uye kushandiswa kwepurasitiki pombi

﹝一﹞Polypropylene pombi (PPR)

(1) Muzvivakwa zvazvino zvekuvaka uye zvekuisa mapurojekiti, mazhinji ekudziya uye ekupa mvura mapombi ePPR (zvidimbu). Zvakanakira zviri nyore uye zvinokurumidza kuisirwa, zvehupfumi uye zvakatipoteredza, huremu huremu, hutsanana uye husina chepfu, kunaka kwekudzivirira kupisa, kushomeka kwekudzivirira, kuita kwakanaka kwekuchengetedza kupisa, hupenyu hurefu uye zvimwe zvakanakira. Iyo dhayamita yepombi yakakura kupfuura dhayamita yezita, uye madhayamita epombi akakamurwa zvakananga kuita DN20, DN25, DN32, DN40, DN50, DN63, DN75, DN90, DN110. Kune akawanda marudzi epombi fittings, ma tee, magokora, pombi dzinosungirira, zvinoderedza, pombi plugs, Pipe clamps, brackets, hangers. Kune pombi dzemvura inotonhora uye inopisa, pombi yemvura inotonhora ichubhu yegirini, uye pombi yemvura inopisa ichubhu dzvuku. Mavharuvhu anosanganisira PPR bhora mavharuvhu, globe mavharuvhu, butterfly mavharuvhu, gedhi mavharuvhu, uye vaya vane PPR zvinhu uye mhangura musimboti mukati.

(2) Nzira dzekubatanidza pombi dzinosanganisira welding, kupisa kunyunguduka uye tambo yekubatanidza. PPR pombi inoshandisa kupisa kunyunguduka kubatana kuti ive yakanyanya kuvimbika, iri nyore kushanda, yakanaka kusimba kwemhepo, uye yakakwirira interface simba. Iyo pombi yekubatanidza inotora ruoko-inobata fusion splicer ye-hot-melt yekubatanidza. Usati wabatanidza, bvisa guruva uye zvinhu zvekunze kubva pamapombi uye zvishandiso. Kana mwenje mutsvuku wemuchina wabatidzwa uye wakagadzikana, gadzirisa mapaipi (zvidimbu) kuti abatanidzwe. DN<50, iyo inopisa kunyunguduka kudzika i1-2MM, uye DN<110, iyo inopisa melt kudzika i2-4MM. Kana uchibatanidza, isa pombi kupera pasina kutenderera Isa mukati mekudziya bhachi kuti usvike pakadzika yakatemerwa. Panguva imwecheteyo, shandisa pombi fittings pamusoro wekupisa musoro pasina kutenderera kwekupisa. Mushure mokunge nguva yekupisa yasvika, pakarepo bvisa mapaipi uye zvigadziro zvepombi kubva pajasi rekupisa uye musoro wekupisa panguva imwe chete, uye uzviise kuhupamhi hunodiwa nokukurumidza uye zvakaenzana pasina kutenderera. A yunifomu flange inoumbwa pajoini. Munguva yakatarwa yekudziya nguva, iyo ichangobva kusungirirwa mubatanidzwa inogona kuverengerwa, asi kutenderera kunorambidzwa zvachose. Paunenge uchidziisa pombi nemafittings, dzivirira kudziyisa kwakanyanyisa uye kuita kuti ukobvu huve hutete. Iyo pombi yakaremara mukukodzera pombi. Izvo zvinorambidzwa zvachose kutenderera panguva inopisa melt intubation uye calibration. Panofanira kunge pasina murazvo wakavhurika panzvimbo yekuvhiya, uye zvinorambidzwa zvachose kubika pombi nemoto wakazaruka. Kana uchibatanidza pombi inopisa uye zvigadziriso zvakamira, shandisa simba rechiedza kudzivirira gokora kubva pakukotama. Mushure mokunge kubatanidzwa kwapera, mapaipi uye zvigadziri zvinofanira kubatwa zvakasimba kuchengetedza nguva yakakwana yekutonhora, uye maoko anogona kusunungurwa mushure mekutonhora kune imwe nzvimbo. Kana iyo PP-R pombi yakabatana nesimbi pombi yekukodzera, pombi yePP-R ine simbi inopinza inofanira kushandiswa seshanduko. Iyo pombi yekumisikidza uye PP-R pombi yakabatana neinopisa-yakanyunguduka socket uye yakabatana nesimbi pombi fitting kana hardware fittings yehutsanana. Paunenge uchishandisa threaded connection, zvinokurudzirwa kushandisa polypropylene raw material tepi sechisimbiso chekuzadza. Kana iyo pombi yakabatana nedziva remop, isa gokora remukadzi (rakaiswa mukati) panoperera pombi yePPR pairi. Usashandise simba rakawandisa panguva yekumisikidza pombi, kuti usakanganise tambo dzakarukwa uye kukonzera kuvuza pakubatanidzwa. Kucheka kwepombi kunogonawo kutemwa nemapaipi anokosha: iyo bayonet yechisi chepombi inofanira kugadziriswa kuti ienderane nehupamhi hwepombi iri kutemwa, uye simba rinofanira kushandiswa zvakaenzana pakutenderera nekucheka. Mushure mekucheka, kuputsika kunofanirwa kuve kwakakomberedzwa neinotenderera inotenderera. Kana pombi yakaputsika, chikamu chinofanira kunge chiri perpendicular kune pombi axis pasina burrs.

﹝二﹞ Rigid Polyvinyl Chloride Pipe (UPVC)

(1) Mapaipi eUPVC (zvidimbu) anoshandiswa kudhiraivha. Nekuda kwehuremu hwayo huremu, corrosion resistance, simba rakawanda, nezvimwewo, inoshandiswa zvakanyanya mukuisa pombi. Mumamiriro ezvinhu akajairika, hupenyu hwesevhisi hunowanzosvika makore makumi matatu kusvika makumi mashanu. Iyo UPVC pombi ine yakatsetseka yemukati madziro uye yakaderera fluid friction resistance, iyo inokunda kukanganisa kuti pombi yesimbi yakakandwa inokanganisa chiyero chekuyerera nekuda kwe ngura uye kuyera. Iyo dhayamita yepombi zvakare saizi imwe yakakura kupfuura dhayamita yezita.Pipe fittingsakakamurwa kuita oblique tees, michinjikwa, magokora, pombi simbi, zvinoderedza, pombi plugs, misungo, pombi dzinosungirira, uye hangers.

(2) Bvisa glue yekubatanidza. Iyo yekunamatira inofanira kuzununguswa isati yashandiswa. Mapaipi uye socket parts zvinofanira kucheneswa. Iyo diki iyo socket gap, zviri nani. Shandisa emery jira kana saw blade kuti roughen pamusoro pekubatana. Geza glue zvishoma mukati me socket uye shandisa glue kaviri kunze kwechigadziko. Mirira kuti glue iome kwe40-60s. Mushure mekuiisa panzvimbo, kutarisisa kunofanirwa kubhadharwa kuti iwedzere kana kuderedza nguva yekuomesa glue zvichienderana nekushanduka kwemamiriro ekunze. Mvura inorambidzwa zvachose panguva yekubatana. Iyo pombi inofanira kuiswa yakatsetseka mumugero mushure mokunge yave panzvimbo. Mushure mekunge mubatanidzwa waoma, tanga kudzosera kumashure. Paunenge uchidzorera, zadza denderedzwa repombi zvakasimba nejecha uye usiye chikamu chekubatana kuti chidzorerwe muhuwandu hwakawanda. Shandisa zvigadzirwa kubva kumugadziri mumwe chete. Paunenge uchibatanidza pombi yeUPVC kune pombi yesimbi, kubatanidzwa kwepombi yesimbi kunofanira kucheneswa uye kusungirirwa, iyo UPVC pombi inopisa kuti ipfave (asi isingatsva), uye yozoiswa papombi yesimbi uye inotonhorera. Zviri nani kuwedzera pombi clamp. Kana iyo pombi yakakuvadzwa munzvimbo yakakura uye inoda kutsiva pombi yose, iyo kaviri socket connector inogona kushandiswa kutsiva pombi. Iyo nzira yekunyungudutsa inogona kushandiswa kubata nekudonha kweiyo solvent bonding. Panguva ino, shandisa mvura mupombi kutanga, uye ita kuti pombi iite kudzvinyirira kusina kunaka, uye wobva wabaya chinamatira pamapores echikamu chinoputika. Nekuda kwekudzvanyirira kwakashata muchubhu, chinonamira chinoyamwa mumapores kuti chizadzise chinangwa chekumisa kubuda. Iyo patch bonding nzira inonyanya kunangana nekudonha kwemaburi madiki uye majoini mumapombi. Panguva ino, sarudza 15-20cm kureba mapaipi emhando imwe chete, cheka iwo nepakati kureba, roughen mukati meiyo casing uye kunze kwepombi kuti ibatiswe zvinoenderana nenzira yekubatanidza majoini, uye vhara nzvimbo inobuda. ne glue. Iyo girazi fiber nzira ndeyekugadzirira resin mhinduro ine epoxy resin uye kurapa mumiririri. Mushure mekuisa iyo resin mhinduro negirazi fiber jira, inokuvadzwa zvakaenzana pamusoro pechikamu chinobuda chepombi kana majoini, uye inova FRP mushure mekurapa. Nekuti iyo nzira ine nyore kuvaka, nyore-ku-master tekinoroji, yakanaka plugging mhedzisiro uye yakaderera mutengo, ine yakakwira kukwidziridzwa uye kukosha kwekushandisa mu-anti-seepage uye leakage muripo.
