Izixhumi zepayipi le-hydraulic hose yensimbi engagqwali yizixhumi ezibalulekile kumasistimu asebenza ngamanzi, futhi ukusebenza kwazo kuthinta ngokuqondile ukuthembeka kwesistimu, ukuqina, nokuphepha. Phakathi kwezinto eziningi, insimbi engagqwali iyinto ekhethwayo yezixhumi zepayipi le-hydraulic ngenxa yokumelana nokugqwala okuhle kakhulu, amandla aphezulu, nokucutshungulwa okuhle. Lesi sihloko sizogxila ezintweni eziyinhloko kanye nezakhiwo ze-stainless steel hydraulic hose connectors.
1. Izakhiwo Eziyisisekelo Zensimbi Engagqwali
Insimbi engagqwali ingxubevange esekelwe ensimbi kanye nokwengezwa kwezakhi zengxubevange njenge-chromium (Cr), i-nickel (Ni), ne-molybdenum (Mo). Isici sayo esiphawuleka kakhulu ukumelana nokugqwala. Lokhu kungenxa yefilimu yokuvikela eminyene ye-chromium oxide (Cr₂O₃) eyakhiwe endaweni yensimbi nge-chromium, evimbela ngokuphumelelayo umoya-mpilo kanye nomswakama ekuqhubekeni nokuhlasela isisekelo sensimbi. Insimbi engagqwali iphinde inikeze amandla aphezulu, -ukumelana nezinga lokushisa okuphezulu okuhle kakhulu, ukumelana nomthelela, kanye nokucutshungulwa okuhle kakhulu, okuyenza ifanelekele amasistimu asebenza ngamanzi angaphansi kokucindezela okukhulu, ukudlidliza okuphezulu, nezimo zokusebenza ezinzima.
2. Izinhlobo Ezivamile Zezinto Zensimbi Engagqwali
Ekwenziweni kwezixhumi ze-hydraulic hose, izinhlobo ezahlukene zensimbi engagqwali, ngenxa yokwakheka kwazo okuhlukahlukene kanye nezakhiwo, zifanelekile ezindaweni zokusebenza ezahlukene. Okulandelayo ezinye izinto ezivamile zensimbi engagqwali:
(1) 304 insimbi engagqwali (18-8 insimbi engagqwali)
Insimbi engagqwali engu-304 iyinsimbi engenasici esetshenziswa kakhulu i-austenitic, futhi ukwakheka kwayo kwamakhemikhali kufaka phakathi u-18% we-chromium kanye no-8% we-nickel (yingakho ibizwa nangokuthi i-18-8 stainless steel). Le nto inokumelana nokugqwala okuhle, ukuqina kanye nokushisela, futhi ilungele amasistimu asebenza ngogesi, ikakhulukazi ezindaweni ezingenazo imidiya egqwala kakhulu. Kodwa-ke, insimbi engagqwali engu-304 ingase ithole ukugqwala komgodi ezindaweni eziqukethe ama-ion e-chloride (njengamanzi olwandle noma izixazululo ezithile zamakhemikhali), ngakho-ke kufanele isetshenziswe ngokuqapha ngaphansi kwezimo ezigqwala kakhulu.
(2) 316 insimbi engagqwali (marine grade stainless steel)
I-316 insimbi engagqwali yengeza u-2-3% we-molybdenum (Mo) ku-304, okuthuthukisa kakhulu ukumelana kwayo nokugqwala kwemigodi nokugqwala, ikakhulukazi ezindaweni eziqukethe ama-ion e-chloride. Ngakho-ke, insimbi engagqwali engu-316 ivame ukusetshenziswa kubunjiniyela basolwandle, okokusebenza kwamakhemikhali kanye nezinhlelo zokugqwala okukhulu kwamanzi. Okuqukethwe kwayo okuphezulu kwe-nickel nakho kuthuthukisa ukuqina kwezinga lokushisa eliphansi futhi ifanele izinga lokushisa elibanzi.
(3) 2205 insimbi engagqwali eyi-duplex
I-2205 duplex stainless steel iyi-austenitic{1}}ferritic duplex stainless steel equkethe cishe u-22% we-chromium, 5% nickel kanye no-3% we-molybdenum. Ibonakala ngamandla aphezulu, ukumelana nokugqwala okuhle kakhulu kanye nokumelana okuhle nokuqhekeka kwe-corrosion. Uma kuqhathaniswa nensimbi engagqwali ye-austenitic, i-2205 duplex stainless steel isebenza kangcono-ezinhlelweni eziphezulu ze-pressure,{9}}ezigugile{9}eziphezulu futhi ifanele uwoyela, igesi nezinkambu zezimboni ezisindayo.
(4) 317L kanye ne-310S insimbi engagqwali (izinhlelo zokusebenza ezikwazi ukumelana nokugqwala okukhethekile{3}}
Ezindaweni ezigqwala kakhulu, njengama-acids aqinile,{0}}i-oxidation ephezulu yezinga lokushisa noma isibabule{1}}equkethe imidiya, izinsimbi ezingenasici ezinokuqukethwe okuphezulu kwe-alloy, njengo-317L (okuqukethwe kwe-molybdenum ephezulu) kanye ne-310S (i-chromium ephezulu, okuqukethwe kwe-nickel ephezulu), kungakhethwa. Nakuba lezi zinto zibiza kakhulu, zinganikeza impilo ende yesevisi ezimeni zokusebenza ezidle kakhulu.
3. Imibandela Yokukhetha Izinto Zensimbi Engagqwali
Lapho ukhetha izinto zokufakwa kwepayipi le-hydraulic hose yensimbi engagqwali, cabangela izici ezilandelayo:
Imidiya esebenzayo: Njengowoyela we-hydraulic, amanzi, nezixazululo zamakhemikhali. Imidiya ehlukene inemiphumela elimazayo eyahlukahlukene kunsimbi engagqwali.
Indawo yokusebenza: Njengokushisa okuphezulu, umfutho ophezulu, ukudlidliza okuphezulu, noma ukuchayeka ngaphandle (isb, izindawo zasolwandle).
Izidingo zokusebenza kwemishini: Njengamandla aqinile, impilo yokukhathala, nokumelana nomthelela.
Izindleko:-Ama-alloy stainless steels aphezulu (afana no-316 no-2205) abiza kakhulu kodwa anikeza ukumelana nokugqwala okuphakeme nempilo yesevisi.
Ukufakwa kwepayipi lepayipi lensimbi engagqwali kwenziwa ikakhulukazi ngezinsimbi ezingenasici ezifana no-304, 316, no-2205. Impahla ngayinye ifanele izimo zokusebenza ezihlukene ngenxa yokwakheka kwayo okuhlukile kwengxubevange{3}} insimbi engagqwali ifaneleka ezindaweni ezijwayelekile zezimboni, i-316 insimbi engagqwali ifaneleka kakhulu ukusetshenziswa olwandle futhi i-durople2 ifaneleka kakhulu futhi iyinsimbi engagqwali2. izindawo ezinokhahlo ezinomfutho ophezulu kanye nokugqoka okuphezulu. Ukukhetha impahla yensimbi engagqwali efanele kungathuthukisa kakhulu ukwethembeka, ukuphepha, nempilo yesevisi yesistimu yakho ye-hydraulic, ngaleyo ndlela kwehlise izindleko zokuyilungisa futhi kuthuthukise ukusebenza kahle kukonke.
