Yuav ua li cas xaiv lub nplhaib sib khi rau lub kaw lus hydraulic?
1, 1. Khoom siv: Nws yog lub foob roj hmab siv dav tshaj plaws thiab pheej yig tshaj plaws. Tsis haum rau siv rau hauv cov kuab tshuaj polar xws li ketones, ozone, nitrohydrocarbons, MEK thiab chloroform. Tsis haum rau siv rau hauv cov kuab tshuaj polar xws li ketones, ozone, nitrohydrocarbons, MEK thiab chloroform. Qhov kub thiab txias siv dav dav yog -40 ~ 120 ℃. Qhov thib ob, HNBR hydrogenated nitrile roj hmab sealing nplhaib muaj kev tiv thaiv corrosion zoo heev, tiv thaiv kua muag thiab compression deformation yam ntxwv, tiv thaiv ozone, tiv thaiv hnub ci, tiv thaiv huab cua zoo. Zoo dua hnav tsis kam dua li roj hmab nitrile. Haum rau kev ntxuav tshuab, tsheb cav systems thiab tub yees systems siv cov tshiab ib puag ncig-phooj ywg refrigerant R134a. Tsis pom zoo kom siv rau hauv cawv, esters, lossis aromatic kua. Qhov kub thiab txias siv dav dav yog -40 ~ 150 ℃. Qhov thib peb, FLS fluorine silicone roj hmab sealing nplhaib muaj qhov zoo ntawm fluorine roj hmab thiab silicone roj hmab, tsis kam roj, tsis kam kuab tshuaj, roj roj tsis kam thiab kub thiab txias siab thiab qis yog qhov zoo. Nws tiv taus kev tawm tsam ntawm cov tshuaj uas muaj cov pa oxygen, cov tshuaj hydrocarbon uas muaj cov kuab tshuaj thiab cov tshuaj chlorine uas muaj cov kuab tshuaj. Feem ntau siv rau kev tsav dav hlau, kev tsav dav hlau thiab tub rog. Tsis pom zoo kom raug ketones thiab cov kua nres. Qhov kub thiab txias feem ntau yog -50 ~ 200 ℃.
2, kev ua tau zoo: Ntxiv rau qhov yuav tsum tau ua ntawm cov khoom siv lub nplhaib sib khi, lub nplhaib sib khi yuav tsum tau them sai sai rau cov xwm txheej hauv qab no: (1) elastic thiab resilient; (2) Lub zog kho tshuab tsim nyog, suav nrog lub zog nthuav dav, elongation thiab lub zog tsim kua muag. (3) Kev ua tau zoo ruaj khov, nws tsis yooj yim rau o hauv nruab nrab, thiab cov nyhuv thermal contraction (Joule effect) yog me me. (4) Yooj yim rau kev ua thiab duab, thiab tuaj yeem tswj tau qhov loj me. (5) tsis corrode qhov chaw sib cuag, tsis ua rau cov khoom siv tsis huv, thiab lwm yam. Cov khoom siv tsim nyog tshaj plaws thiab feem ntau siv los ua kom tau raws li cov kev cai saum toj no yog roj hmab, yog li lub nplhaib sib khi feem ntau yog ua los ntawm cov khoom siv roj hmab. Muaj ntau hom roj hmab, thiab muaj cov roj hmab tshiab tas li, tsim thiab xaiv, yuav tsum nkag siab txog cov yam ntxwv ntawm ntau yam roj hmab, kev xaiv tsim nyog.
3, qhov zoo: 1, lub nplhaib kaw hauv qhov siab ua haujlwm thiab qee qhov kub thiab txias, yuav tsum muaj kev ua haujlwm zoo sealing, thiab nrog kev nce ntawm qhov siab tuaj yeem txhim kho kev ua haujlwm sealing. 2. Kev sib txhuam ntawm lub nplhaib kaw thiab cov khoom txav mus los yuav tsum me me, thiab qhov sib txhuam coefficient yuav tsum ruaj khov. 3. Lub nplhaib kaw muaj zog tiv thaiv corrosion, tsis yooj yim rau laus, muaj lub neej ua haujlwm ntev, tiv thaiv kev hnav zoo, thiab tuaj yeem them rov qab tom qab hnav mus rau qee qhov. 4. Cov qauv yooj yim, yooj yim siv thiab tswj, yog li lub nplhaib kaw muaj lub neej ntev dua. Kev puas tsuaj ntawm lub nplhaib kaw yuav ua rau muaj kev xau, ua rau pov tseg cov khoom siv ua haujlwm, ua rau lub tshuab thiab ib puag ncig muaj kuab paug, thiab txawm tias ua rau kev ua haujlwm tsis zoo thiab cov khoom siv raug mob. Kev xau sab hauv yuav ua rau qhov ua haujlwm volumetric ntawm lub kaw lus hydraulic poob qis, thiab qhov siab ua haujlwm xav tau tsis tuaj yeem ncav cuag, lossis txawm tias txoj haujlwm tsis tuaj yeem ua tiav. Cov hmoov av me me uas nkag mus rau hauv lub kaw lus tuaj yeem ua rau lossis ua rau hnyav dua ntawm kev sib txhuam ntawm cov khoom hydraulic, ua rau muaj kev xau ntxiv. Yog li ntawd, cov ntsaws ruaj ruaj thiab cov khoom siv sealing yog ib feem tseem ceeb ntawm cov khoom siv hydraulic. Qhov kev ntseeg tau thiab lub neej ua haujlwm ntawm nws txoj haujlwm yog ib qho cim qhia tseem ceeb los ntsuas qhov zoo ntawm lub kaw lus hydraulic.
