Zithini Izinto Ezifakelweyo Neziqhoboshelweyo?

Ii-couplings ezigobileyo zii-connections zepayipi ezinokususwa. Kwimveliso yayo, kuthathwa ii-sealing rings kunye ne-couplings ezikhethekileyo. Ayifuni i-welding kwaye ingasetyenziselwa ukufaka iintlobo ngeentlobo zepayipi. Iingenelo zolu qhagamshelo ziquka ukuqhaqha kwazo, kunye nokuthembeka okuphezulu kakhulu, ngamanye amaxesha kudlula izalathisi ezifanayo kwii-welded kunye ne-glued joints.

Iijoyinti zegroove zaqanjwa kudala. KwiMfazwe Yehlabathi Yokuqala, zazisetyenziselwa ukufaka imibhobho enomxube ovuthayo, owawusetyenziswa kwizixhobo zomlilo. Ukususela ngoko, bezisetyenziswa kwiindlela ezahlukeneyo zokusetyenziswa ngoxolo apho kufuneka uqhagamshelo oluthembekileyo nolusemgangathweni ophezulu.

Xa kufakwa umbhobho, ingqwalasela ekhethekileyo inikwa kwiikhonkco. Ukuqina nokuthembeka kwenkqubo, ukukwazi ukumelana nemithwalo ephezulu, kunye nokulula kokugcinwa kwayo kuxhomekeke kuzo. Kangangexesha elide, iintambo zokudibanisa kunye ne-welding bezisetyenziswa njengeendlela eziphambili zokufakela. Namhlanje, ii-couplings ezinemiqolo - ii-clamps ezisuswayo ezinekhola yokutywina - ziya zithandwa kakhulu. Umzimba we-clamp enjalo wenziwe ngentsimbi ethambileyo okanye intsimbi yekhabhoni, kwaye i-insert yenziwe ngezinto zerabha ezimelana nobushushu.

Ngokuxhomekeke kwimithwalo, izihlanganisi zenziwe ngentsimbi ephothiweyo, intsimbi yekhabhoni kunye nezinye izinto ezifanayo. Isihlanganisi siqulathe isibini seehafu kunye ne-O-ring ye-polymer elastiki (i-cuff). Iipayipi ezinee-grooves (ii-grooves) ziqhagamshelwe ngochungechunge, zidibene kwi-joint, kwaye indawo yokutshintsha igqunywe ngesitywina se-o-ring.

Kwinguqulelo yokuqala, imingxunya yokudibanisa imingxunya yayinqunyulwa ngee-milling cutters. Yayiyindlela enzima kakhulu kwaye ayilungelanga. Kule mihla, kusetyenziswa isixhobo esikhethekileyo ukwenza imingxunya - ii-roller grovers. Zahlukile kwindlela yokuqhuba (ngesandla okanye nge-hydraulic) kunye nobubanzi beepayipi ezikwaziyo ukusebenza ngazo. Kwiimeko zoshishino, kusetyenziswa oomatshini bokugrumba abangashukumiyo, ababiza kakhulu ukusetyenziswa ekhaya. Kodwa kwimisebenzi emincinci okanye kwimisebenzi yokulungisa eqhelekileyo, ukusebenza kwesixhobo esisebenza ngesandla kwanele.

Eyona nto imbi ngee-groove joints kukuba zibiza kakhulu kunezinye iintlobo. Yiyo le nto ithintela ukusetyenziswa kwazo ngokubanzi. Izixhobo zokucubungula imibhobho nazo zibiza kakhulu; ii-groover eziphathwayo zibiza amashumi amawaka eeruble. Kodwa ngomsebenzi omncinci, ungaqesha isixhobo; ngethamsanqa, ukukwazi ukwenza umsebenzi nge-groover akunzima kangako.

Iintlobo zezixhobo zokufaka umngxuma

Umgaqo wezixhobo zokufaka ezigobileyo usetyenziselwa ukuphumeza uluhlu olubanzi lwemisebenzi ngexesha lokufakelwa kwemibhobho. Kukho iintlobo ezahlukeneyo zezixhobo ezinjalo:

• ukudibanisa – uhlobo oluqhelekileyo oluyilwe ukudibanisa amacandelo amabini emibhobho enobubanzi obufanayo;

• ingqiniba – into ejikelezayo yombhobho onomphetho omile ngokukodwa ovumela ukufakwa kwe-clamp kube lula;

• iiplagi – izinto ezikuvumela ukuba uvale isebe lombhobho okwethutyana okanye ngokusisigxina okanye uqinisekise uqhagamshelo lwe-groovelock nomsonto;

• ii-adapters eziqinileyo – zikuvumela ukuba uqhagamshele umbhobho onobubanzi obuncinci kunye nokufakelwa kwentambo;

• i-flange etyibilikayo – iqinisekisa ukutshintshwa kwenkqubo ye-groove ukuya kwinkqubo ye-flange;

• ezinye izinto zokufakelwa – uninzi lweemodeli zenzelwe ukwenza ii-compact bends ngqo kwindawo edibeneyo.

Kukho ii-couplings eziqinileyo neziguquguqukayo. Ezokuqala zinamandla angaphezulu afana ne-weld. Iindlela eziguquguqukayo zikuvumela ukuba uhlawulele ukuphambuka okuncinci kwe-engile kwaye umelane noxinzelelo oluhambelanayo kunye noxinzelelo. Izixhobo ezifakwe kwi-grooved zisetyenziselwa imibhobho enobubanzi obuyi-25-300 mm, ngoko ke kulula ukukhetha ii-clamps zemibhobho ngeenjongo ezahlukeneyo. Xa uthenga izixhobo, kuyimfuneko ukucacisa uluhlu lweedayamitha zokusebenza ezenzelwe imveliso. Oku kuya kunceda ukumisela ukuba ukhetho oluthile lukulungele na.
