Ukuze kulungiswe (ukufaka uphawu imifantu nezimbobo) kanye namapayipi axhumayo enziwe ngezinto ezihlukahlukene, kusetshenziselwa amadivaysi akhethekile - ukulungisa ama-couplings.Funda mayelana nokulungisa ama-couplings, izinhlobo zawo ezikhona, ukuklama nokusebenza, kanye nokukhetha okulungile nokusetshenziswa kwale mikhiqizo esihlokweni sethulwe.
Kuyini ukuhlanganisa ukulungisa?
Ukuxhumanisa ukulungisa (i-clamp yokulungisa) - idivayisi yokuvala umonakalo kumapayipi noma ukuxhunywa kwamapayipi okwenziwe ngezinto ezihlukahlukene;Ucezu olulodwa noma ukuhlanganisa okuhlanganisiwe okugxilwe endaweni engaphandle yepayipi ukuze ilivale noma kuqinisekiswe ukuxhumana okuqinile phakathi kwamapayipi amabili, noma ukuxhuma ipayipi ezingxenyeni ezihlukahlukene.
Amapayipi ensimbi, epulasitiki kanye nensimbi-eplastiki, kanye namapayipi enjoloba kanye nepulasitiki ngezinhloso ezihlukahlukene ngesikhathi sokusebenza isikhathi eside abhekene namathonya amabi ahlukahlukene, ngenxa yalokho angonakaliswa.Uma kwenzeka umonakalo omkhulu, ipayipi kufanele ishintshwe ngokuphelele, noma kunjalo, uma kuneziphambeko zendawo - ukuqhekeka noma ukuphuka, kulula futhi kushibhile ukulungisa.Futhi ngokuvamile kunesidingo sokuxhuma amapayipi amabili noma ipayipi elilodwa elinezingxenye ezahlukene, kodwa akunakwenzeka ukushisela lezi zingxenye.Kuzo zonke lezi zimo, amadivaysi akhethekile asiza - ukulungisa ama-couplings.
Lungisa ama-couplings, kuye ngohlobo nomklamo, yenza imisebenzi eminingana:
● Ukulungiswa komonakalo wendawo kumapayipi - imifantu emifushane, ukuphuka, izimbobo, ngokugqwala;
● Ukuxhunywa kwamapayipi amabili anobubanzi obufanayo noma obuhlukile;
● Ukuxhunywa kwamapayipi anemikhiqizo emise okwengeziwe, izifakelo nezinye izingxenye.
Esimweni ngasinye, ukusetshenziswa kwezinhlobo ezithile zokuhlanganisa kanye nezinto ezisizayo kuyadingeka.Ngakho-ke, ngaphambi kokuthenga ingxenye efanele, kufanele uqonde izinhlobo ezikhona zokuhlanganisa, izici nezici zabo.
Izinhlobo kanye nomklamo wokukhanda ama-couplings
Ama-couplings okulungisa emakethe angahlukaniswa ngokwenhloso yawo, ukusebenza nokusebenziseka kwawo, ukwakheka kanye nendlela yokulungisa ipayipi.
Ngokwezinjongo zokuhlanganisa yilezi:
● Ukulungisa - ukubuyisela ukucinana kwepayipi;
● Ukuxhuma - ukuxhuma amapayipi amabili noma ipayipi elinezingxenye ezahlukene;
● I-Universal - ingenza imisebenzi yakho kokubili ukulungisa nokuhlanganisa.
Ngokusho kokusebenza, ukuhlanganisa ukukhanda kuhlukaniswe ngamaqembu amaningana:
● Amapayipi ensimbi - insimbi ekhonjiwe nensimbi;
● Kumapayipi e-HDPE ne-PP anobubanzi obukhulu;
● Ngamapayipi ensimbi-eplastiki enobubanzi obuncane;
● Okwamapayipi aguquguqukayo (amapayipi).
Ukuhlanganisa amapayipi ensimbi kwenziwa ngensimbi ensimbi nensimbi (encane kaningi ipulasitiki), kwamanye amapayipi namapayipi - kusuka kumapulasitiki ezinhlobo ezahlukene (ye-HDPE ne-PP - kusukela ku-polyethylene efanayo ne-polypropylene efanayo, yamapayipi - ahlukahlukene aqinile. namaplastiki aguquguqukayo).
ngokuya ngendlela yokufaka nokuklama, ukuhlanganisa ukulungisa kuhlukaniswe ngamaqembu amabili amakhulu:
● Ukushelela;
● Ihlanganiswe.
Ama-couplings e-sliding yimikhiqizo elula kakhulu ekwakhiweni nasekusetshenzisweni, ngokuvamile eyenzelwe amapayipi e-PP kanye ne-HDPE (indle, amanzi).Ukuhlanganiswa okunjalo kwenziwa ngendlela yepayipi elifushane, izingxenye zazo zokugcina ezinezandiso (izisekelo) zokufakwa kwamasongo enjoloba okuqinisa.Ukuhlanganiswa kufakwe kwipayipi nge-sliding - kufakwe ekugcineni kwamahhala futhi kuthuthela endaweni yokulimala, lapho kulungiswe khona ngeglue noma ngenye indlela.Ama-couplings e-sliding avame ukusetshenziswa njenge-couplings yokuhlanganisa amapayipi amabili noma izinsimbi zokuxhuma, izinsimbi nezinye izingxenye kumbhobho ngemva kokufakwa kwalo lonke uhlelo lwamapayipi.
I-Clutch yokulungisa uhlobo olushelelayo lwe-HDPE
Izingidi ezimbili ezihlanganisiwe
Ukuhlanganisa okuhlanganisiwe kuyimikhiqizo eyinkimbinkimbi kakhulu esetshenziselwa ukulungiswa kwensimbi ekhonjiwe kanye namapayipi ensimbi ezinhlobonhlobo namadayamitha (amapayipi amanzi negesi, indle, njll.).Ukuhlanganisa okunjalo kuhlanganisa izingxenye eziningana ezifakwe epayipini futhi ziqiniswe ngezinsimbi ezinezintambo (ngakho-ke igama lalolu hlobo lomkhiqizo), lihlinzeka nge-crimping eqinile yepayipi endaweni yokulimala.
I-convolutional couplings, yona, ihlukaniswe yaba izinhlobo ezimbili zokuklama:
● Izinhlanganisela eziqinile;
● Itheyiphu (izinsimbi).
Ukuhlanganisa okuqinile kungaba yizingcezu ezimbili kanye neziqephu ezintathu, aqukethe ama-couplings amabili noma amathathu, axhunywe komunye nomunye ngama-fasteners anentambo - ama-bolts amabili, amathathu noma ngaphezulu anamantongomane.Imvamisa, izingxenye zokuhlanganisa izingcezu ezimbili nezintathu zokulungisa zenziwa ngokujikijela noma ukugxiviza ngensimbi eyinsimbi nensimbi.Kodwa muva nje, ama-couplings epulasitiki aklanyelwe amapayipi angama-diameter amancane asetshenziswe kakhulu.Imikhiqizo yepulasitiki inenani elikhulu lokuxhumana okuboshiwe (ngenkathi ama-couplings e-cast iron asebenzisa ama-bolts angaphezu kwamathathu ekuxhumekeni okukodwa), okusabalalisa umthwalo ngokulinganayo futhi avimbele ukubhujiswa kwama-halves okuhlanganisa.Ukuhlangana kuza ne-gasket yerabha eboshwe phakathi kwepayipi nokuhlanganisa, ivala indawo yokunamathisela.
Ukuhlanganisa i-tape kwenziwa ngebhande elilodwa noma amabili ensimbi eguquguqukayo (imvamisa insimbi engagqwali), iziphetho zazo ziqiniswe kanye nezibophelelo ezinentambo, zakha ukukhiya.Ama-couplings afika nesikhiya esisodwa nambili, esimweni sokuqala, kusetshenziswa itheyiphu yegobolondo eyodwa kuphela (kanye nomugqa owengeziwe oweqa indawo yokukhiya), esimweni sesibili, amateyipu amabili, okwenza lolu hlobo lomkhiqizo lufane namabili. -amalunga aqinile ayingxenye.Lokhu kuhlanganisa kusebenzisa i-gasket yerabha.
I-collet-type compression couplings ye-splicing hoses namapayipi epulasitiki obubanzi obuncane abelwe iqembu elihlukile.Isisekelo sokuhlanganisa siyicala lepulasitiki ngendlela yepayipi elifushane elinobubanzi obungaphandle obuhambisana nobubanzi bangaphakathi bamapayipi okumele axhunywe.Iziphetho zecala zihlukaniswa ngama-cutouts zibe amacembe ahlukene aguquguqukayo, futhi eduze nendawo intambo yenziwa.Ukuhlangana kokucushwa okuthile kugoqelwe kuntambo, okuthi, kanye namacembe ezindlu, akhe i-collet clamp.Amapayipi axhunyiwe (ama-hoses) afakwe ku-collet, futhi lapho eboshwe, ama-couplings aboshwe ngokuqinile - lokhu kwakha uxhumano oluqinile futhi oluqinile ngokwanele ngaphandle kokwenza imisebenzi eyengeziwe.
Ukuhlanganisa ukulungisa okuyiziqephu ezimbili
Izingxenye ezintathu ezihlanganisiweukulungisa ukuhlanganisa
Izici zokulungisa ama-couplings
Izici eziyinhloko zokuhlanganisa ukulungisa zihlanganisa ubude bazo (noma indawo yokumboza ipayipi) kanye nobubanzi bamapayipi azoxhunywa.I-convolution eqinile kanye nama-collet couplings ngokuvamile aklanyelwe amapayipi anobubanzi obuthile, futhi imikhono ehlanganisiwe eyenziwe ngamateyipu egobolondo ingagxunyekwa emapayipini obubanzi obuthile bobubanzi (imvamisa lolu bubanzi luyi-5-20 mm kuye ngosayizi wokuhlanganisa) .Ububanzi be-couplings buboniswa ngamamilimitha, kanye namapayipi amanzi negesi - ngamasentimitha.Ubude bokuxhuma ngezinhloso ezehlukene busebangeni lika-70-330 mm, ukuhlangana okuhlanganisiwe kunobude obujwayelekile obungu-200 no-330 mm, ama-sliding couplings amapayipi e-HDPE ne-PP - afinyelela ku-100 mm noma ngaphezulu, kanye ne-collet - engekho ngaphezu kwe-100 mm.
Ngokwehlukana, kuyadingeka ukukhombisa ukuthi kukhona i-collet ne-sliding couplings yobubanzi obuguquguqukayo, eklanyelwe ukuxhuma amapayipi amadayimitha ahlukene.Ama-convolutions okulungisa anobubanzi obungashintshi kuphela.
Ukukhetha kanye nezici zokusebenzisa ama-couplings okulungisa
Lapho ukhetha ukulungiswa noma ukuhlanganisa, umuntu kufanele acabangele uhlobo nobubanzi bamapayipi azoxhunywa, kanye nesimo somsebenzi owenziwe.Indlela elula ukukhetha ama-collet couplings ama-hoses - kumapayipi anjalo kunezingcindezi eziphansi, ngakho-ke ngisho nomkhiqizo wepulasitiki olula uzohlinzeka ngokuxhumeka okuthembekile ngaphandle kokuvuza.Into eyinhloko lapha ukuthola ukuhlanganisa ububanzi bamapayipi akhona.
Ukuze kuthuthukiswe amapayipi endle namapayipi amanzi asekelwe kumapayipi epulasitiki, ama-sliding couplings kufanele asetshenziswe.Ngaphezu kwalokho, ububanzi bomkhiqizo kufanele bufane ncamashi nobubanzi bangaphandle bamapayipi, ngamasayizi amancane noma amakhulu, ukuhlanganisa ngeke kuwele endaweni, noma uxhumano luzovuza.Uma uhlela ukwenza ukuxhumana kwesiqephu esisodwa, khona-ke udinga futhi ukuthenga i-glue ekhethekile.Uma udinga ukulungisa ipayipi lepulasitiki ngaphandle kokuthi kungenzeka ukulisika, ungasebenzisa i-tape convolution coupling.
Ukuze kulungiswe amapayipi ensimbi nensimbi, kuyadingeka ukusebenzisa ama-convolutional couplings.Njengoba sekushiwo kakade, imikhiqizo eqinile kufanele ikhethwe ngokunembile ngokusho kobubanzi bamapayipi, futhi ubukhulu bezinto eziguquguqukayo bungahluka ngamamilimitha ambalwa ukusuka kububanzi bepayipi.Uma udinga ukwenza ukulungisa okuphuthumayo (okuphuthumayo), kungcono ukusebenzisa ama-coupling tape e-single-lock, njengoba akuvumela ukuba uqede ngokushesha ukuvuza ngokuqinisa ama-bolts amabili noma amathathu kuphela.Ukuhlangana kwalezi zinhlobo kuthengiswa kuphelele ngezimpawu zenjoloba, ngakho-ke ukuthengwa kwezingxenye ezengeziwe kuyadingeka ezimweni ezingavamile.
Ukufakwa kwama-couplings okulungisa kulula, kodwa kudinga ukusebenza ngokucophelela kwazo zonke izenzo.I-coupling eshelelayo ifakwa epayipini bese ihamba nayo iye endaweni yomonakalo, lapho ilungiswa khona.I-convolution coupling ifakwe ezingxenyeni: uphawu luyalinyazwa epayipini, ama-couplings angama-half abekwe phezu kwawo, aboshwe ngokuphambana ukuze kuqinisekiswe ukuthi i-crimping efanayo.Uma ufaka i-coupling ye-tape yokukhiya eyodwa, kuyadingeka ukubeka uphawu, ubeke ukuhlanganisa embhobho, bese ufaka i-liner ngaphansi kwendawo yokukhiya, bese uqinisa ama-bolts ngokulinganayo.
Ngokukhetha okulungile nokufakwa kokuhlanganisa ukulungisa, ipayipi izosebenza ngokuthembekile, ngaphandle kokudinga ukulungiswa okuyinkimbinkimbi nokubizayo isikhathi eside.
