Tungsten Carbide Bearings: Ngwọta kachasị maka ngwa nrụpụta ọrụ dị elu

N'ebe ígwè ọrụ mmepụta ihe, bearings na-eje ozi dị ka ọkpụkpụ azụ nke ịrụ ọrụ dị nro, ma ọ bụghị ihe niile ka e kere nha nha. Tungsten carbide bearings apụtala dị ka onye na-agbanwe egwuregwu, na-enye ogologo oge na arụmọrụ na-enweghị atụ nke na-egosipụta ihe ọdịnala dịka nchara ma ọ bụ seramiiki. Ihe mejupụtara tungsten carbide - ihe mejupụtara tungsten na carbon ama ama maka oke ike ya (nke abụọ na diamond) na iguzogide iyi - a na-emepụta bearings ndị a ka ha wee na-eme nke ọma na gburugburu ebe kachasị achọ, na-eme ka ha dị mkpa n'ofe ụlọ ọrụ ndị isi.

1. Ngwuputa Ngwuputa: Na-emeri Abrasion na Ibu Ibu

Ọrụ Ngwuputa na-eche ihe ịma aka siri ike ihu: irighiri ihe na-emebi emebi na ibu mmetụta dị oke egwu na-emebi ngwa ngwa nchara ígwè. Dịka ọmụmaatụ, ndị na-akpụ akpụ na-edozi nkume siri ike (dịka, granite, ọla kọpa) na-ebute ihe ruru 500+ n'arọ nke mmetụta ike kwa okirikiri, ebe usoro ihe na-ebufe ígwè na-ekpughe bearings na abrasion uzuzu mgbe niile. Ngwongwo ígwè na ọnọdụ ndị a na-adakarị n'ime awa 200-300 na-arụ ọrụ, na-amanye awa 4-6 nke oge nkwụsịtụ dị oke ọnụ maka nnọchi.

Tungsten carbide bearings na-ekwu okwu mgbu a na ike 90-95 HRA ha na nguzogide mmetụta dị elu. Otu ogbunigwe ọla kọpa dị na Chile jiri tungsten carbide dị iche iche dochie agba agba nchara n'agba agba ya, nsonaazụ ya gbanwere:

Ogologo ndụ ndụ na-amali elu site na awa 250 ruo awa 2,800 (ogologo 11x), na-ebelata ugboro ugboro site na kwa ọnwa ruo kwa afọ.

Oge nkwụsịtụ gbagoro site na 35%, na-akwalite ikike nhazi ọla kwa ụbọchị site na tọn 1,200 ruo tọn 1,620.

Ọnụ ego nlekọta agbadala site na 68%, n'ihi na mmechi ole na ole wepụrụ ụgwọ ọrụ na akụrụngwa na-enweghị isi.

N'ebe a na-egwupụta kol dị n'okpuru ala, ebe mmiri na uzuzu uzuzu na-eme ka corrosion dịkwuo elu, ọdịdị inert tungsten carbide na-egbochikwa nchara-n'adịghị ka nchara ígwè, nke na-achọ nlele mmanu mmanu kwa izu, carbide bearings chọrọ naanị nyocha kwa ọnwa, na-ebelata ọrụ nlekọta na saịtị.

2. Ụlọ ọrụ mmanụ na gas: Ịnagide oke nrụgide na corrosion

Mkpọpu ala na nnụcha mmanụ na-eweta nrọ abalị abụọ maka bearings: oke nrụgide (ruo 15,000 psi) + okpomọkụ dị elu (300°C+) + mmiri mmiri na-emebi emebi. Ngwongwo ígwè ebe a na-eweda n'ime awa 50-80, dị ka apịtị acid na-erichapụ ihe ndị dị na ígwè na nrụgide nrụgide-ọdịda nke ọ bụla chọrọ ịdọrọ eriri egwu ahụ dum, na-efu 50,000-100,000 n'oge nkwụsịtụ n'otu oge.

Ngwongwo pụrụ iche nke Tungsten carbide na-atụgharị ihe ịma aka ndị a na-abụghị nke:

Ike mkpakọ ha (6,000 MPa) na-eguzogide nrụrụ n'okpuru nrụgide ala, ebe nkwụsi ike nke okpomọkụ ruo 500 ° C na-eme ka ọ dịghị mgbanwe mgbanwe ọ bụla na okpomọkụ dị elu.

Onye isi ọrụ na-ahụ maka ebe mmanụ na Ọwara Mexico jiri tungsten carbide bearings na moto mgbapu ya kwụ ọtọ, na-agbatị ndụ site na awa 70 ruo awa 650. Ụdọ mbelata nke a na-adọta site na ugboro 8 kwa olulu mmiri gaa n'otu oge, na-ebelata oge mmecha nke ọma site na ụbọchị 22 na ịbelata ọnụ ahịa site na $350,000 kwa olulu mmiri.

N'ebe a na-esi mmanụ mmanụ, ebe nfuli na-ebu mmanụ crude nwere sọlfọ bara ụba, nguzogide corrosion tungsten carbide na-enwukwa. Otu ụlọ ọrụ refinery Texas kọrọ na mgbe ọ gbanwere na carbide bearings na nfuli mbufe crude ya, ọdịda akara (nke nchara nchara nchara) si na 12 kwa afọ gbadara 2, na nrụpụta mgbapụta na-abawanye site na 9% n'ihi mbelata esemokwu.

3. Ụlọ ọrụ mmiri na mmiri ọgwụ: Na-emeri corrosion na mmiri mmiri

Ụgbọ mmiri mmirier shafts na chemical pumps na-alụ ọgụ mmiri nnu mgbe niile ma ọ bụ ikpughe ihe mgbaze - nchara nchara ebe a na-agba nchara n'ime ọnwa 3-6, na-eduga n'ịhazi adịghị mma na nkwụsị. Maka ụgbọ mmiri ndị dị n'ikpere mmiri, iji dochie ihe na-ebu ihe na-ebu ibu na-achọ ịkwanye nkụ, na-efu 20,000-50,000 kwa ụbọchị.

Tungsten carbide's chemical inertness (ọ na-eguzogide 99% nke ihe mgbaze ụlọ ọrụ na mmiri nnu) na-ewepụ ihe ize ndụ a:

Otu ụgbọ mmiri na-akụ azụ na Norwegian na-eji tungsten carbide propeller bearings kwadoro ụgbọ mmiri ya, na-agbatị ndụ site na ọnwa 6 ruo afọ ise. Ugboro mmiri nkụ na-agbada site n'afọ ruo otu ugboro n'afọ ise ọ bụla, na-echekwa $120,000 n'otu ụgbọ mmiri maka ụgwọ mmezi.

N'ime ụlọ ọrụ kemịkalụ nke na-emepụta sulfuric acid, tungsten carbide bearings na agitator shafts nọchiri ụdị ígwè dị iche iche-na mbụ, nchara ígwè na-ada ada kwa ọnwa 2 n'ihi corrosion acid, mana carbide bearings na-arụ ọrụ na-aga n'ihu ruo ọnwa 18, na-ebelata nkwụsị na-enweghị atụmatụ site na 90%.

4. Ike mmeghari ohuru (Ike ikuku): Na-adịgide adịgide na ihe ndị dị n'èzí

Ndị na-emepụta turbine ikuku na-eche ịma jijiji na-ebute ikuku mgbe niile (ruo 50 Hz) + mgbanwe okpomọkụ (-40°C ruo 60°C). Ngwongwo ígwè na turbine isi ogwe na-adakarị n'ime afọ 3-4, ma dochie ha chọrọ mgbazinye kreen (15,000-30,000 kwa ụbọchị) na ụbọchị 3-5 nke nkwụsịtụ.

Ọdịiche dị ala nke Tungsten carbide nke esemokwu (0.05, ọkara nke ígwè) na ihe ndị na-eme mkpọtụ na-edozi nke a:

Ugbo ikuku German rụnyere tungsten carbide bearings na 20 n'ime turbines 2.5 MW ya. N'ime afọ 5, ọ dịghị nke ọ bụla n'ime ụgbọ ala carbide dara, ebe nchara ígwè na turbines dị n'akụkụ chọrọ nnọchi ugboro abụọ. Ugbo ahụ zọpụtara $450,000 na ụgwọ mmezi yana mmụba ike site na 4% (n'ihi nkwụsị dị nta).

5. Atụmanya ahịa nke Tungsten Carbide Bearings: Ndị ọkwọ ụgbọ ala na-eto eto na ọnọdụ ọdịnihu

Ahịa tungsten carbide bearings zuru ụwa ọnụ dị njikere maka uto siri ike n'ime afọ iri na-abịanụ, nke nkwalite ụlọ ọrụ na-akwalite, ọchịchọ maka akụrụngwa ntụkwasị obi dị elu, yana mgbasawanye nke ngalaba ojiji.
