I-Pickling and passivation ye-stainless steel elbow - isilinganiso soketshezi lwe-pickling kanye noketshezi oludlulayo

2024-02-11

Iyini i-pickling kanye nokwelashwa kwe-passivation ye-elbow yensimbi engagqwali?

Izikali ze-oxide ezimnyama neziphuzi zizovela ngesikhathi sokucutshungulwa kwendololwane yensimbi engagqwali. Ukuze kuthuthukiswe ukubukeka nokumelana nokugqwala kwendololwane yensimbi engagqwali, indololwane yensimbi engenasici ecutshunguliwe kufanele ifakwe emanzini anosawoti futhi ingadluliswa. I-Stainless steel elbow pickling ukususa isikali se-oxide esikhiqizwa ngemva kokushisela kanye nokucubungula izinga lokushisa eliphezulu ukuze kukhanye futhi kucwebezele. I-stainless steel elbow passivation ukwenza ifilimu ye-oxide ene-chromium njengento eyinhloko endaweni ephathwayo ukuze kuvinjelwe i-oxidation yesibili, ngaleyo ndlela kuthuthukiswe ikhwalithi engaphezulu yokulwa nokugqwala yendololwane yensimbi engagqwali futhi andise impilo yesevisi yemishini.

Ukunqunywa nokunwetshwa kwamapayipi ensimbi engagqwali ngokuvamile kuphathwa nge-pickling passivation paste kanye noketshezi lwe-pickling passivation. I-Pickling passivation paste ivumelanisa ukuchotshozwa kanye ne-passivation futhi ikuqedele esinyathelweni esisodwa, iguqule inqubo yendabuko yokukhetha kanye ne-passivation. Ubuchwepheshe bamakhemikhali, ukusebenza okulula, ukwakhiwa okulula kanye nezindleko eziphansi. Ifanele ukudweba indawo enkulu kanye nokufakwa kwamapayipi ensimbi engagqwali ububanzi obukhulu. Isixazululo se-pickling passivation sifanelekile ekusebenzeni kokucwiliswa kwamapayipi amancane wensimbi engenasici.

Ake sikhulume ngesilinganiso sokuxuba uketshezi oluvame ukusetshenziswa lokukha amanzi kanye noketshezi oludlulayo lokufakwa kwamapayipi ensimbi engagqwali. I-Pickling liquid, i-passivation liquid kanye nefomula yokunamathisela yokunamathisela

Isixazululo se-Pickling: 20% nitric acid + 5% hydrofluoric acid + 75% amanzi

Isixazululo se-passivation: 5% nitric acid + 2% potassium dichromate + 93% amanzi

Izinyathelo zokusebenzisa isixazululo se-stainless steel pickling passivation:

1. Phatha amabala kawoyela phezu kwendololwane yensimbi engagqwali bese uyipholisha;

2. Thela isixazululo se-passivation esitsheni sepulasitiki. Kuye ngezinto ze-elbow yensimbi engagqwali kanye nezinga le-oxidation, ungasebenzisa isisombululo sokuqala noma usinciphise ngesilinganiso se-1: 1-4 ngaphambi kokusetshenziswa;

3. Gcoba indololwane yensimbi engagqwali ukuze iphathwe oketshezini, ngokuvamile ekushiseni okujwayelekile, noma ingashiswa ibe ngama-40-50 degrees ukuze icutshungulwe. Isikhathi sokucwiliswa emanzini imizuzu engu-3-20 noma ngaphezulu, futhi isikhathi esithile kanye nezinga lokushisa kunganqunywa ngokuvumelana nesimo sangempela;

4. Kuze kube yilapho ukungcola ebusweni be-elbow yensimbi engagqwali kukhishwe ngokuphelele futhi kubonakala kumhlophe ngokulinganayo okucwebezelayo, okusho ukuthi i-pickling ne-passivation iphelile, khipha indololwane yensimbi engagqwali, uyihlanza ngamanzi ahlanzekile, bese uyomisa.

Ngemuva kokukhetha kanye nokwelashwa kwe-passivation yokufakwa kwamapayipi ensimbi engagqwali, ngeke kuthinte ukuhanjiswa kwezinto, kuguqule ukwakheka kwezinto ezibonakalayo, noma kuthinte izakhiwo zokubopha njengokufafaza.

1. Izikhundla ezimaphakathi zalezi ziphetho ezimbili zihlukile

Amaphoyinti amaphakathi emiphetho emibili yesinciphisi sensimbi engenasici awekho ku-eksisi efanayo.

Amaphoyinti amaphakathi emiphetho emibili yesinciphisi esigxilile sensimbi engagqwali aku-eksisi efanayo.

2. Izindawo zokusebenza ezihlukene

Olunye uhlangothi lwensimbi engagqwali eccentric reducer luyisicaba. Lo mklamo wenza kube lula ukuphuma kwe-exhaust noma uketshezi lwe-liquid futhi kusize ukulondolozwa. Ngakho-ke, ngokuvamile isetshenziselwa amapayipi oketshezi avundlile.

Indawo emaphakathi yesinciphisi esigxilile sensimbi engagqwali isemgqeni, ohambisana nokugeleza koketshezi futhi onokuphazanyiswa okuncane nephethini yokugeleza koketshezi ngesikhathi sokunciphisa ububanzi. Ngakho-ke, ngokuvamile isetshenziselwa ukunciphisa ububanzi begesi noma amapayipi oketshezi aqondile.

3. Izindlela zokufaka ezihlukene

Izinciphisi zensimbi engagqwali zibonakala ngesakhiwo esilula, ukwenziwa kalula nokusetshenziswa, futhi zingahlangabezana nezidingo ezahlukahlukene zokuxhuma amapayipi. Izimo zohlelo lokusebenza zifaka phakathi:

Uxhumano lwamapayipi oluvundlile: Njengoba amaphuzu aphakathi nendawo yeziphetho ezimbili zensimbi engagqwali eccentric reducer engekho kulayini ovundlile, afaneleka ukuxhunywa kwamapayipi avundlile, ikakhulukazi lapho ububanzi bepayipi budinga ukushintshwa.

I-pump inlet kanye nokufakwa kwevalvu elawulayo: Ukufakwa kweflethi okuphezulu nokufakwa kweflethi okuphansi kwensimbi engenasici eccentric reducer kufanelekile ukufakwa kwe-pump inlet kanye nevalvu yokulawula ngokulandelanayo, okuzuzisa ukukhipha nokukhipha.

Izinciphisi zensimbi engagqwali zibonakala ngokuphazanyiswa okuncane ekugelezeni koketshezi futhi zifanele ukwehlisa ububanzi begesi noma amapayipi oketshezi aqondile. Izimo zohlelo lokusebenza zifaka phakathi:

Igesi noma ukuxhunywa kwepayipi loketshezi olume mpo: Njengoba indawo ephakathi nendawo yeziphetho ezimbili zesinciphisi esigxilile sensimbi engagqwali iku-eksisi efanayo, ifanele ukuxhunywa kwegesi noma amapayipi oketshezi aqondile, ikakhulukazi lapho kudingeka khona ukuncishiswa kobubanzi.

Qinisekisa ukuzinza kokugeleza koketshezi: Isinciphisi esigxilile sensimbi engagqwali sinokuphazamisana okuncane nephethini yokugeleza koketshezi phakathi nenqubo yokunciphisa ububanzi futhi singaqinisekisa ukuzinza kokugeleza koketshezi.

4. Ukukhethwa kwezinciphisi ze-eccentric kanye nezinciphisi ezigxilile ezinhlelweni ezingokoqobo

Kuzinhlelo zokusebenza zangempela, izinciphisi ezifanele kufanele zikhethwe ngokuvumelana nezimo ezithile kanye nezidingo zokuxhunywa kwamapayipi. Uma udinga ukuxhuma amapayipi avundlile futhi ushintshe ububanzi bepayipi, khetha i-stainless steel eccentric reducers; uma udinga ukuxhuma igesi noma amapayipi oketshezi aqondile futhi ushintshe ububanzi, khetha izinciphisi zensimbi ezingenasici.
