Kuyini Ukufakwa Kwe-Grooved & Couplings?

Ama-coupling ama-grooved axhumeka kalula ngamapayipi. Ngokwakhiwa kwayo, izindandatho ezikhethekile zokuvala nokuhlanganisa zithathwa. Ayidingi i-welding futhi ingasetshenziswa ukufaka izinhlobo eziningi zamapayipi. Izinzuzo zokuxhuma okunjalo zifaka ukuhlakazeka kwazo, kanye nokuthembeka okuphezulu kakhulu, ngezinye izikhathi kudlula izinkomba ezifanayo zamajoyini ahlanganisiwe nanamathiselwe.

Amalunga e-Groove asungulwa kudala. EMpini Yezwe Yokuqala, zazisetshenziselwa ukufaka amapayipi anengxube evuthayo, eyayisetshenziswa ezitsheni zomlilo. Kusukela lapho, ziye zasetshenziswa ezinhlobonhlobo zezicelo ezinokuthula lapho kudingeka khona ukuxhumana okuthembekile nokusezingeni eliphezulu.

Lapho ufaka ipayipi, ukunakwa okukhethekile kukhokhwa ekuxhumekeni. Ukuqina nokuthembeka kwesistimu, amandla okumelana nemithwalo ephezulu, kanye nokulula kokulungiswa okulandelayo kuncike kukho. Isikhathi eside, ukuxhumeka kwentambo kanye nokushisela kwakusetshenziswa njengezindlela zokufaka eziyinhloko. Namuhla, ama-couplings anemigoqo - ama-clamp ahlukanisekayo anekhola yokuvala - athola ukuthandwa. Umzimba we-clamp enjalo wenziwe nge-ductile iron noma i-carbon steel, futhi okufakiwe kwenziwa ngezinto ezisekelwe ku-rubber ezivikela ukushisa.

Kuye ngemithwalo, ama-couplings ayenziwe nge-cast iron, carbon steel nezinye izinto ezifanayo. Ukuhlangana kuqukethe ipheya lamahhafu kanye ne-elastic polymer O-ring (cuff). Amapayipi ane-grooves (ama-grooves) axhunywe ochungechungeni, ahlangene kuya kuhlangene, futhi iphuzu lokushintsha limbozwe uphawu lwe-o-ring.

Enguqulweni yokuqala, ama-grooves okuhlanganiswa kwe-groove ayesikwa ngabasiki be-milling. Kwakuyindlela eyinkimbinkimbi futhi engalungile. Namuhla, ithuluzi elikhethekile lisetshenziselwa ukwenza ama-grooves - ama-roller groovers. Zihluke ngendlela yokushayela (i-manual noma i-hydraulic) kanye nobubanzi bamapayipi abakwazi ukusebenza ngawo. Ezindaweni zezimboni, kusetshenziswa imishini yokugaya emile, ebiza kakhulu ukusetshenziswa ekhaya. Kodwa ngenani elincane lomsebenzi noma umsebenzi wokulungisa ovamile, ukusebenza kwethuluzi elisebenza ngesandla kwanele.

I-drawback kuphela yamalunga e-groove yizindleko zabo eziphakeme, eziphakeme kunezinye izinhlobo. Yilokhu okuvimbela ukusetshenziswa kwazo kabanzi. Amathuluzi okucubungula amapayipi nawo ayabiza; ama-groovers aphathwayo abiza amashumi ezinkulungwane zama-ruble. Kodwa ngenani elincane lomsebenzi, ungaqasha ithuluzi; ngenhlanhla, ukwenza kahle umsebenzi nge-groover akunzima ikakhulukazi.

Izinhlobo zokufakwa kwe-groove

Umgomo wokufakwa kwe-grooved usetshenziselwa ukusebenzisa imisebenzi eminingi ngesikhathi sokufakwa kwamapayipi. Kunezinhlobo eziningana zokufakwa okunjalo:

• ukuhlanganisa - inguqulo yakudala eyenzelwe ukuxhuma izingxenye ezimbili zamapayipi obubanzi obufanayo;

• indololwane - isici esijikelezayo sepayipi elinomphetho owenziwe ngokukhethekile ovumela ukufakwa kalula kwe-clamp;

• ama-plug - izingxenye ezikuvumela ukuthi uvale okwesikhashana noma unomphela igatsha lepayipi noma uqinisekise ukuxhunywa kwe-groovelock ngentambo;

• ama-adaptha agxilile - akuvumela ukuthi uxhume ipayipi yobubanzi obuncane ngokulungiswa kwentambo;

• i-slip-on flange - iqinisekisa ukuguqulwa kwesistimu ye-groove ohlelweni lwe-flange;

• okunye ukufakwa - amamodeli amaningi enzelwe ukudala ukugoba okuhlangene ngqo ekuhlanganyeleni.

Kukhona ama-couplings aqinile futhi aguquguqukayo. Ezangaphambili ziye zanda amandla aqhathaniswa ne-weld. Izinketho eziguquguqukayo zikuvumela ukuthi unxephezele ngokuchezuka okuncane kwe-angular futhi umelane nokucindezelwa komugqa kanye nokushuba. Ukufakwa kwe-grooved kusetshenziselwa amapayipi ububanzi obuyi-25-300 mm, ngakho-ke kulula ukukhetha izinsimbi zamapayipi ngezinhloso ezihlukahlukene. Lapho uthenga ukufakwa, kuyadingeka ukucacisa uhla lwama-diameters okusebenza lapho umkhiqizo uhloselwe khona. Lokhu kuzosiza ekunqumeni ukuthi inketho ethile ikulungele yini.
