style="text-indent:25px">限位開(kāi)關(guān)就是用以限定機(jī)械設(shè)備的運(yùn)動(dòng)極限位置的電氣開(kāi)關(guān)。限位開(kāi)關(guān)有接觸式的和非接觸式的。接觸式的比較直觀，機(jī)械設(shè)備的運(yùn)動(dòng)部件上，安裝上行程開(kāi)關(guān)，與其相對(duì)運(yùn)動(dòng)的固定點(diǎn)上安裝極限位置的擋塊，或者是相反安裝位置。當(dāng)行程開(kāi)關(guān)的機(jī)械觸頭碰上擋塊時(shí)，切斷了（或改變了）控制電路，機(jī)械就停止運(yùn)行或改變運(yùn)行。由于機(jī)械的慣性運(yùn)動(dòng)，這種行程開(kāi)關(guān)有一定的“超行程”以保護(hù)開(kāi)關(guān)不受損壞。非接觸式的形式很多，常見(jiàn)的有干簧管、光電式、感應(yīng)式等，這幾種形式在電梯中都能夠見(jiàn)到。當(dāng)然還有更多的先進(jìn)形式。限位開(kāi)關(guān)主要有開(kāi)關(guān)元件，接線端子、開(kāi)關(guān)操動(dòng)件、傳動(dòng)部分組成，根據(jù)開(kāi)關(guān)觸頭接通和斷開(kāi)機(jī)械機(jī)理，開(kāi)關(guān)元件有以下兩類(lèi)：慢動(dòng)開(kāi)關(guān)：開(kāi)關(guān)的接通和斷開(kāi)動(dòng)作切換時(shí)間與開(kāi)關(guān)的操動(dòng)速度有關(guān)，操動(dòng)速度越快，開(kāi)關(guān)的切換也越快?？靹?dòng)開(kāi)關(guān)：開(kāi)關(guān)的接通和斷開(kāi)的轉(zhuǎn)換時(shí)間與開(kāi)關(guān)**動(dòng)的速度無(wú)關(guān)，只要開(kāi)關(guān)操動(dòng)部件**動(dòng)到一定位置，開(kāi)關(guān)便發(fā)生接通和斷開(kāi)切換，此過(guò)程時(shí)間一般為彈簧彈跳所需時(shí)間，此時(shí)間極短，為一常數(shù)。</p><p style="text-indent:25px">限位開(kāi)關(guān)構(gòu)造分為三類(lèi)：1、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(lèi)。A型是用O型環(huán)或薄膜密封的，由于密封橡膠沒(méi)有外露，在**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(guò)來(lái)，有可能會(huì)損壞橡膠帽。因此，要根據(jù)使用場(chǎng)所的不同選用A型或B型。而柱塞型仍然通過(guò)柱塞的往復(fù)運(yùn)動(dòng)壓縮或吸進(jìn)空氣。為此，如果長(zhǎng)時(shí)間將柱塞壓入，限位開(kāi)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(kāi)關(guān)內(nèi)部全部空氣量的20%以?xún)?nèi)。另外，為了延長(zhǎng)微動(dòng)開(kāi)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(duì)于柱塞的運(yùn)動(dòng)，在中途停止按壓微動(dòng)開(kāi)關(guān)輔助柱塞的行程。2、鉸鏈擺桿型：在擺桿端部(滾珠)，柱塞的行程量根據(jù)擺桿的比例擴(kuò)大，因此，一般不使用OT吸收機(jī)構(gòu)。3、旋轉(zhuǎn)擺桿型當(dāng)動(dòng)物接近靜物時(shí)，開(kāi)關(guān)的連桿驅(qū)動(dòng)開(kāi)關(guān)的接點(diǎn)引起閉合的接點(diǎn)分?jǐn)嗷蛘邤嚅_(kāi)的接點(diǎn)閉合。</p><div
