style="text-indent:25px">限位開關(guān)限位開關(guān)就是用以限定機械設(shè)備的運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，機械設(shè)備的運動部件上，安裝上行程開關(guān)，與其相對運動的固定點上安裝極限位置的擋塊，或者是相反安裝位置。當行程開關(guān)的機械觸頭碰上擋塊時，切斷了（或改變了）控制電路，機械就停止運行或改變運行。由于機械的慣性運動，這種行程開關(guān)有一定的“超行程”以保護開關(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。當然還有更多的先進形式。限位開關(guān)是一種常用的小電流主令電器。利用生產(chǎn)機械運動部件的碰撞使其觸頭動作來實現(xiàn)接通或分斷控制電路，達到一定的控制目的。通常，這類開關(guān)被用來限制機械運動的位置或行程，使運動機械按一定位置或行程自動停止、反向運動、變速運動或自動往返運動等。在電氣控制系統(tǒng)中，限位開關(guān)的作用是實現(xiàn)順序控制、定位控制和位置狀態(tài)的檢測。用于控制機械設(shè)備的行程及限位保護。構(gòu)造：由操作頭、觸點系統(tǒng)和外殼組成。</p><p style="text-indent:25px">限位開關(guān)主要是有一個擋塊壓住限位開關(guān)的觸頭，那么限位開關(guān)里面常開變常閉，常閉變常開，這種開關(guān)一般都用在一個運動物件兩個極端的限位，因為這種開關(guān)機械方面出故障比較低，使用環(huán)境要求不高，因此用的比較廣。感應(yīng)式限位開關(guān)，一般通過物體靠近限位開關(guān)有感應(yīng)常開變常閉，常閉變常開。但是這種開關(guān)使用的環(huán)境要求高一點，因此沒有機械式限位開關(guān)應(yīng)用廣fan。沒有記錯的話感應(yīng)式限位開關(guān)一般在氣缸，等一些部件上檢測位移或者壓力。機械式限位開關(guān)結(jié)構(gòu)簡單，成本低，對于控制要求不太敏感，環(huán)境要求一般，感應(yīng)式對于環(huán)境要求敏感，具體問題具體分析具體解決，成本較高。限位開關(guān)觸點材料的不斷更新，其可通斷次數(shù)非常高。</p><div

style="text-indent:25px">限位開關(guān)構(gòu)造分為三類：1、活塞型：根據(jù)密封方法不同，有表中的A型和B型2個種類。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**工作機械的切割碎屑方面功能較強大，但其反面影響是，有可能會將砂子、切割粉末等壓入活塞的滑動面。B型雖然不會把砂子、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)運動壓縮或吸進空氣。為此，如果長時間將柱塞壓入，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)計時，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，為了延長微動開關(guān)的壽命，在這一構(gòu)造內(nèi)部設(shè)置了一個OT吸收機構(gòu)，該OT吸收機構(gòu)采用OT吸收彈簧，用以吸收殘余的柱塞的行程。該機構(gòu)相對于柱塞的運動，在中途停止按壓微動開關(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)擺桿的比例擴大，因此，一般不使用OT吸收機構(gòu)。3、旋轉(zhuǎn)擺桿型限位開關(guān)有接觸式的和非接觸式的?；窗卜辣尬婚_關(guān)生產(chǎn)廠商</p><p
