I-Tungsten Carbide Thread Nozzle yePetroleum kunye noShishino lweMichiza

Intshayelelo  

Kwimizi-mveliso yepetroleum kunye neekhemikhali, ukuqina kwezixhobo phantsi kweemeko ezinzima-ezifana nokuhamba kwamanzi oxinzelelo oluphezulu, amaqhekeza abrasive, kunye neendawo ezinobungozi-zibalulekile. I-tungsten carbide (WC) imilomo yemisonto iye yavela njengesisombululo esiphezulu, inikezela ukuxhathisa okungenakuthelekiswa nanto, ukuxhathisa ukubola, kunye namandla omatshini xa kuthelekiswa nezinto zemveli ezifana nentsimbi okanye iiseramikhi. Eli nqaku liphonononga uyilo, izibonelelo, ukuveliswa, kunye nokusetyenziswa kwe-tungsten carbide thread nozzles kumacandelo e-oyile, igesi, kunye neekhemikhali.  

 1. Yintoni iTungsten Carbide Thread Nozzle?  

Umbhobho womsonto yinxalenye yobunjineli obuchanekileyo esetyenziswa kwiinkqubo zokulawula ulwelo ukulawula indlela yokuhamba, uxinzelelo, kunye nesantya. Xa zakhiwe kwi-tungsten carbide, le mibhobho ibonisa ubulukhuni obukhethekileyo (1,400–2,200 HV) kunye nokuqina, nto leyo ebenza ukuba bafanelekele imekobume yemizi-mveliso erhabaxa.  

 Iimpawu eziphambili:  

✔ Ukumelana ne-Ultra-High Wear Resistance - Ukumelana namasuntswana abrasive kudaka lokomba kunye nolwelo olugcwele isanti.  

✔ I-Corrosion Resistance - Yenza kwi-acidic (H₂S / CO₂) kunye neemeko ze-alkaline.  

✔ Uzinzo lobushushu obuphezulu – Igcina imfezeko yolwakhiwo ukuya kuthi ga kwi-1,000°C.  

✔ Uyilo olunemisonto-Iqinisekisa ukufakwa ngokukhuselekileyo kwimibhobho yoxinzelelo oluphezulu.

- I-Hydraulic Fracturing (I-Fracking): Ixhathisa ukhukuliseko olusuka kulwelo oluthwele ipropant.  

 2.2 UCongo kunye nePetrochemical Processing  

- Imibhobho yokutofa yeCatalyst: Ikhusela ukunxitywa kweFCC (Fluid Catalytic Cracking) iiyunithi.  

- I-Desulfurization Spray Nozzles: Imelana nokuba sesichengeni se-asidi ye-sulfuric.  

 2.3 IziTyalo zeMichiza kunye nezoMbane  

- IMibhobho yokucoca i-High-Pressure: Isetyenziselwa ukucocwa kwetyhubhu yebhoyili.  

-I-Corrosive Fluid Disspersion: Ixhathisa uhlaselo lweekhemikhali kwiinkqubo zokudlulisa i-asidi/alkali.  

3. Kutheni iTungsten Carbide igqwesa izinto zeMveli?  

Ipropathi yeTungsten Carbide Steel engagqwali (316L) iCeramic (Al₂O₃)

Ukuqina (HV) 1,400–2,200 200–300 1,500–1,800

Ukuchasana neMpembelelo Phezulu kuPhantsi okuPhantsi (Buncinci)

Ukuchasa ukuRhakala Kugqwesileyo (WC-Ni) Phakathi (I-Pitting) Imbi (HF/NaOH)

Ubushushu obuphezulu (°C) 1,000 800 1,600 (Umothuko weThermal)

Izinto eziluncedo:  

- 5-10x ubude obude kunemibhobho yentsimbi kwiimeko ezinqabileyo.  

- Yehlisa ixesha lokuphumla ngokunciphisa ukutshintshwa kwemilomo.  

- Ukuchaneka okuphezulu kokuhamba ngenxa yoguquko oluncinci olubangelwa ukhukuliseko.  

4. Inkqubo yokwenziwa kweMiphumo yeMisonto yeWC  

 4.1 I-Powder Metalurgy  

1. Ukuxutywa kwePowder: I-WC powder + Co/Ni binder (6-12%).  

2. Ukucinezela: I-Cold isostatic pressing (CIP) ye-uniform density.  

3. I-Sintering: I-vacuum sintering kwi-1,400-1,500 ° C ukwenzela ukuxinana okupheleleyo.  

 4.2 Umatshini kunye nokuThwaya  

- Ukugaya: Ukusila ivili ledayimani ukwenzela ukunyamezela okuchanekileyo (± 0.01mm).
