Black Steel Washers

Pamusoro pekuita kusviba, Black Steel Washers inogona zvakare kushandisa phosphate kurapwa kuti iwane rima grey kune dema pamusoro. Iyo porous chimiro cheiyo phosphate firimu ine yakanakisa kuchengetedza mafuta uye inogona kuderedza zvakanyanya friction coefficient panguva yekusangana. Zvinoenderana neISO 9717 mirau yekuchinjisa phosphate coatings, iyo yepasi density yephosphate coating haifanire kunge iri pasi pemagiramu mashanu paskweya mita, uye density yepasi yekuchinjisa phosphate coating haifanire kunge iri pasi pemagiramu mashanu paskweya mita. Zvinoenderana ne946 friction coefficient test, mushure mekupfekedzwa nemafuta ekuti-ngura, friction coefficient yebearing surface yakadzikira kubva pa0.16 kusvika 0.10, yakadzikira inosvika 37%. Kana iyo torque yekusimbisa yeM12 bhaudhi iri 100 Nm, zvichibva pane friction coefficient uye preload force conversion formula, iyo axial preload simba inogona kuverengerwa ingangoita 42,000 N, iyo inenge 20% yakakwirira kupfuura iyo inoiled state. Panguva imwecheteyo, tembiricha yekurapa phosphating yakadzikira, iyo ine zvishoma zvinokanganisa kurongeka kweiyo gasket. Zvinoenderana neiyo ISO 4759-1 kushivirira mwero, iyo yekunze dhayamita kutsauka ichiri kuchengetedzwa mukati mekuwedzera kana kubvisa 0.3 mm. Inokodzera kushandiswa seyekuyeresa gasket kune hydraulic pombi flanges uye inorema mabhesi emidziyo.

 

 

Iyo anti-oxidation kugona kwemawacha simbi nhema munzvimbo yakakwirira-inotembiricha zvakanyanya zvinoenderana nekugadzikana kwepasi payo oxide layer. Kana tembiricha yekushanda ichipfuura 300 madhigirii Celsius, firimu rakasviba rinogona kuora uye kuratidzika kusviba dzvuku, asi michina ye matrix inoramba yakagadzikana. Zvinoenderana neASTM E8 yakakwirira-temperature tensile test method, simba regoho regasket matrix rinodonha kusvika pa85% yemutengo wetembiricha yemumba pa350 degrees Celsius, inova 190 MPa. Panguva ino, maererano neASME PCC-1 nzira yekuongorora yekubatanidza mabhaudhi epamusoro-tembiricha, mwero wekunyunguduka munzvimbo yakakora yegasket iri pasi pe 0.001 mm paawa, izvo zvinokwana kuchengetedza bhaudhi pretightening simba rinodzora zvisingapfuure 5% mushure memaawa zana ekuenderera mberi kwekushanda.

 

 

Muvacuum kana yakachena nharaunda umo mafuta ekuzora asinga shandiswe, dema simbi washer vanotsamira pane yavo yepamusoro microporous chimiro kuti vape imwe dhigirii yekuoma kwekudonhedza kunyorova. Zvinoenderana neyakachinjika vibration bvunzo zvinoenderana neDIN 267 Chikamu 26, mushure me10,000 vibrations pafrequency ye20 Hz uye amplitude ye 1 mm, yakasara preload simba rekuchengetedza mwero ingangoita makumi manomwe neshanu muzana eiyo kukosha kwekutanga, iyo inokwana gumi nemaviri% yakakwirira kupfuura yakajairwa isina kuvharwa washers ane simbi yakatsetseka. Naizvozvo, yakafanira kubatanidza node mumapombi anopisa einjini inobvira mukati uye mapaipi{10}}anopisa anopisa anoda kusunungura zviri pakati nepakati uye kudzivirira kusvibiswa kwemafuta.

 

 

 

 

 

 

 

 

Wana madhirowa kubva kune vatengi kana gadzira madhirowa zvichienderana nemasamples avo kana zvakatemwa.

Iwo madhirowa, zvigadzirwa, kurapwa kwepamusoro, uye zvimwe zvinopupurirwa nemapato ese.

 

 

 

 

Ipa quote, ita shuwa kuti huwandu hweodha hwakarurama, uye sanganisira zvese zvinoenderana,

senge mazwi ekubhadhara, mazwi ekutengeserana, rudzi rwekurongedza, nezvimwe.

 

 

 

Tevedzera madhirowa ekutanga uye sampuli chaizvo paunenge uchigadzira zvinhu.

Yakanyatsorongedzwa uye yakaendeswa kune vatengi zvichitevera kuongororwa kwekupedzisira.
