style="text-indent:25px">選用合適的骨架油封的類別推薦：對(duì)于大型重機(jī)械設(shè)備所選用的骨架油封一般都要求有較高的剛性，因此優(yōu)先選用SB、TB型油封。當(dāng)對(duì)油封的剛性有更高的要求時(shí)，推薦選用SA、TA型外骨架油封。對(duì)于旋轉(zhuǎn)扭矩較低的轉(zhuǎn)軸，如小型電機(jī)，應(yīng)選用不帶彈簧的骨架油封推薦選用VC、VB、KV、KB型油封。骨架油封一般用在高、低速旋轉(zhuǎn)軸，工況為：旋轉(zhuǎn)運(yùn)動(dòng)線速≤15m/s、往復(fù)運(yùn)動(dòng)速度≤0.1m/s、工作壓力﹤0.05MPa；的環(huán)境下使用；上述所說(shuō)的一些骨架油封參數(shù)，均會(huì)標(biāo)準(zhǔn)件的工作情況的參數(shù)推薦。所以要配合自身的實(shí)際情況去對(duì)推薦的油封進(jìn)行篩選使用。廣東丁晴橡膠油封哪里買</p></div>
