style="text-indent:25px">限位開關(guān)就是用以限定機(jī)械設(shè)備的運(yùn)動極限位置的電氣開關(guān)。限位開關(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)動部件上，安裝上行程開關(guān)，與其相對運(yùn)動的固定點(diǎn)上安裝極限位置的擋塊，或者是相反安裝位置。當(dāng)行程開關(guān)的機(jī)械觸頭碰上擋塊時，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，這種行程開關(guān)有一定的“超行程”以保護(hù)開關(guān)不受損壞。非接觸式的形式很多，常見的有干簧管、光電式、感應(yīng)式等，這幾種形式在電梯中都能夠見到。當(dāng)然還有更多的先進(jìn)形式。限位開關(guān)主要有開關(guān)元件，接線端子、開關(guān)操動件、傳動部分組成，根據(jù)開關(guān)觸頭接通和斷開機(jī)械機(jī)理，開關(guān)元件有以下兩類：慢動開關(guān)：開關(guān)的接通和斷開動作切換時間與開關(guān)的操動速度有關(guān)，操動速度越快，開關(guān)的切換也越快?？靹娱_關(guān)：開關(guān)的接通和斷開的轉(zhuǎn)換時間與開關(guān)**動的速度無關(guān)，只要開關(guān)操動部件**動到一定位置，開關(guān)便發(fā)生接通和斷開切換，此過程時間一般為彈簧彈跳所需時間，此時間極短，為一常數(shù)。</p><p style="text-indent:25px">限位開關(guān)，指為保護(hù)內(nèi)置微動開關(guān)免受外力、水、油、氣體和塵埃等的損害，而組裝在外殼內(nèi)的開關(guān)，尤其適用于對機(jī)械強(qiáng)度和環(huán)境適應(yīng)性有特殊要求的地方。形狀大致分為橫向型、豎向型和復(fù)合型。限位開關(guān)大致上是由五個構(gòu)成要素組成的。限位開關(guān)主要由開關(guān)元件，接線端子，開關(guān)操動件，傳動部分組成，根據(jù)開關(guān)觸頭接通和斷開機(jī)械機(jī)理，開關(guān)元件有下屬二類。1.緩動開關(guān)：緩動開關(guān):開關(guān)的接通和斷開動作切換時間與開關(guān)操作頻率有關(guān)，操作頻率越快，開關(guān)的切換也越快。2.速度開關(guān)：速度開關(guān):開關(guān)的接通和斷開的轉(zhuǎn)換時間與開關(guān)**作的頻率無關(guān)，只要開關(guān)**作到一定位置，開關(guān)便發(fā)生接通和斷開切換，此過程時間一般為彈簧彈跳所需時間，此時間段為一常數(shù)。防爆限位開關(guān)適用于非常惡劣的操作條件。</p><div

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)需要有多個移動部件，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)靠近的時候就會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很多，可以根據(jù)需求進(jìn)行選擇，但是它可能會受到極端溫度波動和水分侵入而導(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?？煽?，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。限位開關(guān)是一種低成本的檢測元件。鹽城機(jī)械式限位開關(guān)廠家</p><p

style="text-indent:25px">什么是限位開關(guān)？其實(shí)限位開關(guān)的種類比較多。限位開關(guān)一般分為機(jī)械式、電子感應(yīng)式和光電式三種。雖然它們的工作原理不同，但它們的功能是完全相同的。它是一種用于檢測移動電氣設(shè)備工作位置的裝置。讓我先談?wù)剻C(jī)械限位開關(guān)。限位開關(guān)通常被稱為行程開關(guān)或位置開關(guān)。其功能與控制按鈕相同。它可以將機(jī)械位移信號轉(zhuǎn)換成電信號，但觸點(diǎn)的動作不是用手按的。它是利用生產(chǎn)設(shè)備中某些運(yùn)動部件的機(jī)械位移與開關(guān)相撞，使觸點(diǎn)移動，完成對某一電路通斷的控制，從而控制機(jī)械動作或程序執(zhí)行。如果行程開關(guān)安裝在工作機(jī)器的末端以限制其行程，則稱為限位開關(guān)或端部開關(guān)。鹽城機(jī)械式限位開關(guān)廠家</p></p><br
