Inqubo yokukhetha amapayipi ensimbi

Okubizwa kanjalo kusetshenziswa i-hydrofluoric acid nesisombululo se-nitric acid ukugeza i-steel surface oxide ekhiqizwa ngemva kokwelashwa ngokushisa.Isetshenziswa ekubunjweni kwesixazululo namanani wesilinganiso: HF (3-8%), HNO3 (10-15%), H2O (inani elisele) lapho kucutshungulwa izinga lokushisa lesisombululo ku-40-60 °C.

Inqubo yokukhetha ipayipi lensimbi:
Hlanza imfucumfucu ekuchithekeni kukawoyela → Obhasikidi abalayishiwe → Ukukhipha amafutha ngamakhemikhali → Ukuhlanza amanzi ashisayo → Ukuhlanza amanzi abandayo → Ukugqwala kwamakhemikhali → ukugezwa kwezinwele ezicindezelayo → Ukugeleza kwamanzi okugeza → Ukuhlanza amanzi ashisayo → Komisa → isivivinyo

Inqubo pickling kufanele sinake amaphuzu alandelayo:
Iphuzu lokuqala:ukwamukelwa kokufakwa ohlwini okungenayo, ukucaciswa, ubuningi nokuqondisa ukusika ikhwalithi ukwamukelwa okungafanelekile kokumisa isikhashana ukucosha kanye nesaziso esifike ngesikhathi somnyango wokulawula ikhwalithi noma indawo yokusebenzela.

Iphuzu lesibili:Okokuqala ukufaka i-asidi ngokuhambisana nenani lesilinganiso sokulawula phansi kwesitolo, i-asidi eyengeziwe kufanele isakazwe ngokulinganayo ku-pickling tank, kunokwengeza engxenyeni eyodwa yethangi le-asidi;bese ulawula usayizi wenani le-steam, ukuze ulawule izinga lokushisa lezinsimbi ze-asidi ngokuvamile ulawula izinga lokushisa le-asidi ukuze linqobe kancane (cishe ama-degrees angu-60), futhi akufanele lilawule izinga lokushisa liphezulu kakhulu noma umuzwa wokubila. i-asidi;okusele iwukuba ukuhlela inqubo site steel ipayipi ikhadi, ukuhlukanisa phakathi inombolo luhlaka ezahlukene, Ngenxa yokuba khona izinhlobo ezahlukene steel pickling umehluko isikhathi.

Iphuzu lesithathu:ukulawulwa kwenqubo yokukhetha, kanye nesinyathelo esibaluleke kakhulu.Imikhiqizo ehlukene amapayipi ensimbi kanye nokuqeda insimbi pickling kanye degreasing.Yikuphi, ukuphakamisa imikhiqizo amapayipi ensimbi angasetshenziswa ngokuqondile intambo yenayiloni ethangini lokuqoqa, ukulenga ipayipi lensimbi elifashini kufanele libe nomsila wekhanda eliphansi, ukuze i-asidi ikwazi ukungena ngempumelelo emgodini wepayipi;ipayipi lensimbi eliqediwe elilenga ku- pickling yokugeza i-asidi, ngezikhathi ezifanele ukuphakamisa ipayipi lensimbi emuva ethangini le-asidi, ukuze kube ukukhishwa kwe-oxidation ebusweni bepayipi lensimbi ngaphakathi nangaphandle kwe-Picchi lokhu ukuze kukhishwe ipayipi lensimbi, kancane kancane liguquguquke kakhulu. ngamajethi wamanzi anengcindezi ephezulu okugeza ibhobo lamapayipi, bese ipayipi lensimbi lingene kumafolda alengayo ku-asidi cwilisa ngesikhathi esifanele amapayipi ensimbi alenga ithangi le-asidi kufanele acwiliswe imizuzu eyi-10 kusinki bese kancane kancane abe namagatsha hashaza indawo yangaphakathi nangaphandle. .Ipayipi likawoyela kufanele lichithe uwoyela ongaphezulu kanye ne-lubrication lime cwilisa kusinki imizuzu eyi-10 bese uhlanza imbobo ngayinye yegatsha;ukugingqa imikhiqizo eqediwe epayipini likawoyela kusinki ukuze licwile isikhathi esithile uqiniseke ukuthi ipayipi lensimbi selipholile ngokuphelele, ipayipi lensimbi lingene kubhavu we-asidi isigamu somzuzu, bese lingena kusinki bese liguquguquka lilingana negatsha.

Iphuzu lesine:inqubo yokukhetha ngemva komsebenzi wokuhlola.Ukuhlolwa okuqediwe kwepayipi lensimbi ye-pickling kugxile ngokuyinhloko ukuhlanzeka kwe-oxide kwezindawo zangaphakathi nangaphandle zepayipi lensimbi, ikakhulukazi ekuhlanzekeni kwe-bore yangaphakathi, ukusetshenziswa okungcono kakhulu kwentambo DON ngokuhlola ifomula, inani lesampula akufanele libe ngaphansi kuka-10%.Okulandelwa ukuhlolwa kwe-asidi blot indawo yensimbi kanye nokwehluleka ukuhlola umbala wepayipi lensimbi kufanele kube ukukha kabusha;kude amafutha ebusweni bepayipi lensimbi akufanele kuchitheke uwoyela, ukunakwa okukhethekile kufanele kungabikho iziphetho zepayipi le-asidi eliphumayo.
