style="text-indent:25px">限位開關(guān)的活塞型根據(jù)密封方法不同，有表中的A型和B型2個(gè)種類。A型是用O型環(huán)或薄膜密封的，由于密封橡膠沒有外露，在限制工作機(jī)械的切割碎屑方面功能較強(qiáng)大，但其反面影響是，有可能會(huì)將砂子、切割粉末等壓入活塞的滑動(dòng)面。B型雖然不會(huì)把砂子、切割粉末等壓入，且密封性能優(yōu)于A型，但由于熾熱的切割碎屑飛濺過來，有可能會(huì)損壞橡膠帽。因此，要根據(jù)使用場所的不同選用A型或B型。而柱塞型仍然通過柱塞的往復(fù)運(yùn)動(dòng)壓縮或吸進(jìn)空氣。為此，如果長時(shí)間將柱塞壓入，限位開關(guān)內(nèi)的壓縮空氣逸失，內(nèi)部壓力將與大氣壓相同，即使急于讓柱塞復(fù)位，柱塞卻有遲緩復(fù)位的傾向。為了避免發(fā)生這種故障，設(shè)計(jì)時(shí)，根據(jù)柱塞的壓入將空氣的壓縮量控制在限位開關(guān)內(nèi)部全部空氣量的20％以內(nèi)。另外，為了延長微動(dòng)開關(guān)的壽命，在這一構(gòu)造內(nèi)部設(shè)置了一個(gè)OT吸收機(jī)構(gòu)，該 OT吸收機(jī)構(gòu)采用OT吸收彈簧，用以吸收殘余的柱塞的行程。該機(jī) 構(gòu)相對于柱塞的運(yùn)動(dòng)，在中途停止按壓微動(dòng)開關(guān)輔助柱塞的行程。限位開關(guān)是一種常用的小電流主令電器。安徽防爆限位開關(guān)生產(chǎn)廠家</p><p

style="text-indent:25px">四種限位開關(guān)的應(yīng)用：1.機(jī)械限位開關(guān)其實(shí)不需要電源操作就能處理大電流的負(fù)載，因?yàn)樗峭ㄟ^和目標(biāo)的直接接觸來檢測位置的機(jī)電裝置，使用的是干觸電，沒有極性或電壓敏感性，這樣的開關(guān)需要有多個(gè)移動(dòng)部件，它的重復(fù)性是相對較差的。2.彈簧限位開關(guān)是通過吸引目標(biāo)磁場嘞檢測目標(biāo)位置的，它的內(nèi)部有金屬插腳，這樣的簧片元件是磁敏感的，磁性目標(biāo)靠近的時(shí)候就會(huì)ji活，它具有機(jī)械開關(guān)的所有優(yōu)點(diǎn)，但是簧片元件非常脆弱，玻璃管也是可能被破壞的，因此高振動(dòng)的應(yīng)用可能導(dǎo)致它發(fā)出假信號。3.感應(yīng)式限位開關(guān)是通過能量場的干擾來確定目標(biāo)位置的，這種裝置不需要物理接觸，而且沒有各種移動(dòng)部件，后期維護(hù)也沒有那么復(fù)雜，而且此類裝置的外形和尺寸有比較多，可以根據(jù)需求進(jìn)行選擇，但是它可能會(huì)受到極端溫度波動(dòng)和水分侵入而導(dǎo)致各種影響的發(fā)生。4.極限限位開關(guān)采用的是混合技術(shù)通過電磁灶確定目標(biāo)位置的，它非常耐用，而且在各種惡劣環(huán)境中應(yīng)用也非常可靠，它不需要物理接觸或外部電源，綜合了以上幾種類型開關(guān)的所有優(yōu)點(diǎn)，有著非常寬廣的工作范圍。安徽防爆限位開關(guān)生產(chǎn)廠家</p></p><br
