Cov qauv no xyuas kom meej tias cov tshuab ntxhua khaub ncaws square los ntawm cov tuam txhab sib txawv tuaj yeem hloov pauv tau thiab ua tau raws li qhov yuav tsum tau ua ntawm cov ntawv thov tshwj xeeb. Thaum xaiv cov square washers, nws yog ib qho tseem ceeb kom paub tseeb tias kev ua raws li tus qauv tsim nyog los xyuas kom meej kev sib raug zoo thiab kev ntseeg tau.
6. Kev xaiv thiab kev teeb tsa kev txiav txim siab
Txhawm rau kom ua tiav qhov kev ua tau zoo ntawm square washers, ntau yam tseem ceeb yuav tsum tau txiav txim siab thaum xaiv thiab teeb tsa:
6.1 Load Requirements
Xaiv cov khoom siv ntxhua khaub ncaws thiab thickness raws li qhov xav tau clamping load. Rau siab -load daim ntaub ntawv, hardened carbon steel los yog stainless hlau washers yog nyiam, thaum lub teeb yuag cov ntaub ntawv (xws li, aluminium) yog haum rau tsawg- daim ntawv thov load.
6.2 Ib puag ncig tej yam kev mob
Txheeb xyuas qhov chaw uas lub tshuab ntxhua khaub ncaws yuav siv. Rau corrosive ib puag ncig (xws li, marine, tshuaj), xaiv stainless hlau, tooj dag, los yog yas washers. Rau siab - kub daim ntawv thov, xaiv cov ntaub ntawv uas muaj kub tsis kam (xws li titanium, Inconel).
6.3 Cov khoom siv substrate
Muab cov khoom siv ntxhua khaub ncaws rau lub substrate kom tsis txhob galvanic corrosion. Piv txwv li, siv stainless hlau washers nrog txhuas substrates, thiab tooj dag ntxhua nrog tooj liab substrates. Rau cov substrates mos (xws li, ntoo, yas), xaiv cov ntxhua khaub ncaws nrog thaj tsam loj dua los tiv thaiv kev poob dej.
6.4 Fastener Compatibility
Xyuas kom lub tshuab ntxhua khaub ncaws lub qhov nruab nrab ntawm lub qhov taub yog qhov sib tw ntawm lub shank txoj kab uas hla. Ib lub qhov me me dhau lawm yuav tiv thaiv kev ntxig ntxig ntxig, thaum lub qhov loj dhau yuav txo qis kev ruaj ntseg thiab thauj khoom.
6.5 Kev Txhim Kho Qhov Zoo Tshaj Plaws
Thaum lub sij hawm installation, xyuas kom meej tias lub tshuab ntxhua khaub ncaws yog zaum tiaj tus tiv thaiv lub substrate thiab fastener taub hau / txiv ntseej. Tsis txhob hla dhau - zawm lub fastener, vim qhov no tuaj yeem ua rau lub tshuab ntxhua khaub ncaws, substrate, lossis fastener nws tus kheej. Siv torque wrenches los siv lub zog clamping pom zoo, thiab tshuaj xyuas lub tshuab ntxhua kom puas (xws li, khoov, tawg) tom qab kev teeb tsa.
7. Cov lus xaus
Square washers yog ntau yam thiab tseem ceeb fastener accessory uas muaj qhov tshwj xeeb zoo hauv kev faib khoom, tiv thaiv- kev sib hloov, thiab kev ruaj ntseg. Lawv cov duab plaub ua rau lawv tsim tshwj xeeb rau cov ntawv thov uas cov tshuab ntxhua khaub ncaws yuav tsis muaj kev ua tau zoo, xws li siab -ib puag ncig kev vibration, kev tsim vaj tsev, thiab kev sib raug zoo nrog cov square lossis duab plaub. Los ntawm kev xaiv cov khoom tsim nyog, ua raws li cov qauv kev lag luam, thiab ua raws li kev teeb tsa kom raug, cov tshuab ntxhua khaub ncaws tuaj yeem txhim kho kev ntseeg siab, ua haujlwm ntev, thiab kev nyab xeeb ntawm cov khoom sib dhos thoob plaws ntau yam kev lag luam.
