Hlau Fixing Washers

Hlau Fixing Washers ua los ntawm cov hlau tsis muaj steel ua si ntev - qhov chaw nyob ntev thiab tiv thaiv - lub luag haujlwm xoob hauv cov kav dej tshuaj thiab cov dej hiav txwv. Lawv yog ua los ntawm 316L stainless hlau thiab tau ua cov tshuaj kho. Raws li cov kev cai ntawm ASTM A240 ntawm pitting corrosion kuj sib npaug tus nqi, PRE tus nqi ntawm cov khoom tsis tsawg tshaj 25. Qhov tseem ceeb pitting kub tuaj yeem ncav cuag 45 degrees Celsius raws li ASTM G48 txoj kev. Nyob rau hauv ib qho chaw ntub dej uas muaj cov tshuaj chloride ions, nws tau dhau tsib feem pua ​​​​sodium chloride nruab nrab ntsev tshuaj tsuag tshuaj ntsuam raws li ASTM Tom qab B117 raug rau 1,200 teev, tsis muaj xeb liab nyob rau saum npoo ntawm lub gasket thiab tsis muaj corrosion expansion tau pom ntawm ntug ntawm cov hniav qauv. Nws tsis kam mus rau intergranular corrosion tau txheeb xyuas los ntawm ASTM A262 xeem. Nws tuaj yeem ua kom ntseeg tau tias cov hniav nto ntawm lub gasket ruaj khov ib txwm tswj kom zoo haum nrog cov khoom sib txuas hauv cov kua qaub tawm, yog li tswj hwm lub zog ua ntej thiab tsis ua kom qis vim qhov sib xyaw ntawm cov khoom siv corrosion. Nyob rau tib lub sijhawm, tom qab ua haujlwm txias, Vickers hardness ntawm gasket ncav cuag HV 250 txog 280 raws li ASTM E18, uas yog li 30% siab dua li lub xeev annealed. Qhov hardness theem no ua rau tus hniav qauv tsim micro-embed txog li 0.1 hli sib sib zog nqus thaum nias rau hauv stainless hlau los yog aluminium alloy puag khoom. Kev ntsuas tiv thaiv- nplawm coefficient tau nce los ntawm 3 ntawm xoom mus rau 0.5, uas ua rau muaj txiaj ntsig zoo ntawm kev sib txuas ntawm qhov sib txuas.

Hauv cov txheej txheem kho kom raug, cov hlau ruaj khov feem ntau yog tsim los nrog kev tso cov lugs lossis cov duab tshwj xeeb uas tsis yog - lub voj voog sab nraud kom txwv txoj kev sib hloov ntawm bolts los yog qhov chaw nyob rau hauv lub voj voog ncig. Sab hauv txoj kab uas hla yog tswj raws li H13 kam rau ua ntawm ISO 4759-1. Rau lub tshuab ntxhua khaub ncaws nrog ib txoj kab uas hla ntawm kaum millimeters, qhov sib txawv tiag tiag yog khaws cia nyob rau hauv ntxiv lossis rho tawm xoom.015 millimeters kom ntseeg tau tias muaj kev cuam tshuam me ntsis nrog cov ntsia hlau thiab tsis txhob ntxhua khaub ncaws deflection thaum lub sijhawm teeb tsa. Raws li ISO 1101 geometric kam rau ua tus qauv, qhov flatness ntawm lub tshuab ntxhua khaub ncaws tsis ntau tshaj 0.02 hli, thiab qhov sib npaug ntawm ob sab yog tswj tsis pub dhau 0.03 hli. Qhov no ua kom ntseeg tau tias qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv tsis pub tshaj 0.05 hli thaum ntau daim sib dhos, thiab tsis cuam tshuam rau qhov raug mob stroke ntawm cov xov hloov. Raws li nws qhov tseeb qhov chaw muaj peev xwm thiab cov yam ntxwv kev sib txhuam ruaj khov, hom gasket no nyiam siv rau hauv kev hloov kho kom pom tseeb ntawm cov twj paj nruag photoelectric thiab micro valve txwv cov khoom. Tom qab rov qab disassembly thiab sib dhos peb caug zaug, qhov kev sib txawv ntawm qhov chaw yog tseem tsawg dua 0.02 hli, ua kom ntseeg tau tias qhov rov ua dua qhov tseeb ntawm kev ua haujlwm ntev ntawm cov khoom siv.

Tau txais cov duab kos los ntawm cov neeg siv khoom lossis tsim cov duab kos raws li lawv cov qauv lossis cov qauv tshwj xeeb.

Cov duab kos, cov khoom siv raw, kev kho deg, thiab lwm yam ntsiab lus tau lees paub los ntawm ob tog.

Muab cov lus tsocai, xyuas kom meej tias qhov kev txiav txim kom muaj nuj nqis yog qhov tseeb, thiab suav nrog tag nrho cov ntsiab lus tseem ceeb,

xws li cov nqe lus ntawm kev them nyiaj, cov nqe lus ntawm kev lag luam, hom ntim, thiab lwm yam.

Ua raws li cov duab kos thiab cov qauv raws nraim thaum tsim cov khoom.

Nws tau ua tib zoo ntim thiab xa mus rau cov neeg siv khoom tom qab kev tshuaj xyuas zaum kawg.
