Funda i-Internal Pipe Blasting Nozzle Ezicini Eziyisithupha

Ama-nozzles angasetshenziswa kuwoezihlukahlukeneizinhlobo zendawo ukuqeda, hhayi kuphela kodwa futhingaphakathi kwephezulu, njengepayipi. Kulokhu, sidinga ukusebenzisaidivayisi,iIpayipi langaphakathi eliqhumisa umlomo elinamathuluzi ahlukene ahlobene，ukuze sifinyelele ubulukhuni bethu obufunayo.

Isimiso

Njengenqubo yokunye ukuqhunyiswa kwesihlabathi, kuhilela izinto ezintathu ezibalulekile zokuqhuma kwamapayipi angaphakathi, i-compressor yomoya, izinto zokuqhuma, kanye nombhobho wokuqhuma kwepayipi wangaphakathi. Umoya uphushwa kuqala ukuze uthwale izinhlayiya ezivuthayo ebhodweni lempahla eqhumayo. Khona-ke ingxube igelezela kubhobho lokuqhuma kwepayipi langaphakathi ngepayipi elixhumayo. Ekugcineni, izinhlayiya ezilumayo ziyafafazwa ukuze kuhlanzeke ingaphakathi lepayipi elisukela kusayizi ongu-19mm kuya ku-900mm ngephuzu lokuchezuka lombhobho. Ithiphu ikhiqiza iphethini yokuqhuma ukuze ikhiphe okusho ukuthi i-abrasive ihlakazwa ngamadigri angu-360, ukuze kuthuthukiswe ukuhlanzwa ngokuphumelelayo.

Isakhiwo

Isitayela esivamile, sihlukaniswe ikakhulukazi izingxenye ezintathu ezihlanganisa ithiphu lokuchezuka, umzimba we-nozzle, kanye nokuhlanganisa okuhlanganisaamaholoholo intambo noma umucu ocolekile. Ngesinye isitayela esikhethekile, ikhanda eliqhumayo elizungezayo endaweni yethiphu evamile yokuchezuka ukudubula ama-abrasive.

I-Liner Materials

Impahla ye-liner ihlanganisa izinhlobo ezimbili, i-Boron Carbide (B4C) ne-Tungsten Carbide (TC). I-B4C ineengasindi, izinga lokushisa eliphezulu, ukuguga, nokumelana nokugqwala. Ukuqina kwayo kungokwesibili ngemva kwedayimane. I-TC futhi inobulukhuni obuphezulu, ukumelana nokugqoka ngentengo eshibhile. Icala ngokuvamile lenziwe nge-Aluminium.

Amathuluzi

Amadayimitha angaphakathi wamapayipi ahlukene adinga imibhobho ehambisanayo namathuluzi ahlobene.

I-ID yepayipi engu-19-50mm: Kumadayamitha epayipi angaphakathi asuka ku-19mm kuya ku-50mm, inqubo yokuqhuma idinga imibhobho yesitayela se-lance kanye namasethi amakholola ukuze kutholwe umlomo wombhobho phakathi kwepayipi. Ngokusho kobukhulu obuhlukahlukene bamapayipi, sidinga ukuhlomisa amasethi amakhola afanelekile.

I-ID yepayipi engu-50-135mm: Kububanzi bepayipi bangaphakathi obusuka ku-50 ukuya ku-135mm, inezinketho ezimbili zamathuluzi okuqhuma. Eyodwa iyisibhobho esinamasethi amakhulu amakhola (Enkulu iyatholakala ku-135 pipe I.D.). Enye ingubhobho elinenqola ephakathi nendawo efana nesikelo. Njengomsebenzi weqoqo lekhola, inqola emaphakathi iwu-eyenza ukuthi umlomo wombhobho uhambe kahle epayipini.

I-ID yepayipi engu-135-900mm: Kulesi simo, idinga imibhobho enenqola ejikelezayo ekhanda enamakhanda aphendukayo amaningana ukuze idubule ngendlela elimazayo.(amathuluzi esithombe)

Imisebenzi

Ukuze kuqedwe ubuso bepayipi yangaphakathi, kuvame ukusetshenziswa ukususa ukugqwala, okwenza mezobuchwephesheizingxenye ukuthuthukisa okuningi.Ukuqhunyiswa kwesihlabathi kweiudonga lwangaphakathi ngokuyinhloko luyindlela yokufafaza ngesivinini esiphezulu esekelwe esimisweni sokucindezelwa komoya njengamandla. Ama-abrasives asetshenziswa ekukhipheni ukugqwala anezinhlobo ezahlukene njengesihlabathi se-garnet, isihlabathi se-quartz, imayini yethusi, njll. Inqubo enemininingwane ilandelayo.

Step1: Ngaphambi sandblasting, ebusweniipayipi langaphakathiizohlanzwa kuqala. Ukuhlanzwa kwendawo kubalulekile ngoba kuthinta ngqo ukunamathela kwengubo yonke.

Step2: Ukuchayeka elangeni kuyasiza ukubambezeleka impilo yesevisi ye-coating. Ngaphezu kwalokho, zikhona ezinye izindlela ezifanaukuhlanza i-solvent,i-asidiukukha.

Step3: Lungiselela i-compressor yomoya, bese uqondanisa umlomo wombhobho nendawo ozophathwa ngayo, futhi ugcine ibanga licishe libe ngu-15 ~ 30 cm.. Singasebenzisa amathuluzi okuqhuma afanelekile ukuze sithole ama-nozzles ngaphakathi kwamapayipi ahamba kahle.

Isinyathelo 4: SI-andblasting inomthelela kanye nomphumela wokusikangaphakathiiipayipi, futhi ingaphezulu lingakwazifinyelelaukuhlanzeka okuthile kanye namahhadlahhadla ahlukene.

Ukunaka

1. Ngesikhathi sokwakhiwa kwe-sandblasting, ukuvikelwa kokuphepha komuntu siquegqokekufanele zigqokwe ukugwema ukulimala emzimbeni.

2. Ngesikhathi sokwakhiwa, kufanele kugcinwe okungenani abantu ababili ukugwema isimo esiphuthumayo esingakwazi’ngibhekane nomuntu oyedwa.

3. Ngaphambi kokusebenzisa i-compressor yomoya, ipayipi lokungenisa umoya kanye nomshini we-sandblasting kudingeka uhlolwe ukuze kubekwe uphawu.

4. Umfutho womoya we-compressor yomoyangangokunokwenzeka’tidlule ku-0.8MPa, futhi ivalvu yomoya idinga ukuvulwa kancane uma kusetshenziswa i-compressor yomoya.
