3、本產(chǎn)品不能安裝在具有性氣體存在的環(huán)境。 4、執(zhí)行機(jī)構(gòu)內(nèi)部不能留有空壓，防止執(zhí)行機(jī)構(gòu)意外旋轉(zhuǎn)。 5、在具有性氣體的環(huán)境使用時，電源接線一定要用取得防爆認(rèn)證的電纜和接頭進(jìn)行連接。 6、打開外蓋前要切斷電源。 7、為了維護(hù)產(chǎn)品打開TOP-870外蓋時，首先要在切斷電源過30秒之后打開外殼。 8、2個電源接口中，不使用的接口要用通過防爆認(rèn)證的接頭完全密封。 9、接線時要注意正負(fù)極接反。 10、接線時要避免因用力過大表皮脫落。 11、根據(jù)現(xiàn)場和防爆規(guī)定要正確接地。</p><p style="text-indent:25px">限位開關(guān)就是用以限定機(jī)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(jī)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(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)械就停止運行或改變運行。由于機(jī)械的慣性運動，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)。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。</p><div

style="text-indent:25px">限位開關(guān)的日常保養(yǎng)方法：較為前提的，在限位開關(guān)選擇上一定要選擇大品牌，質(zhì)量好認(rèn)證完善的產(chǎn)品。徐州閥門限位開關(guān)符號</p><p style="text-indent:25px">在旋轉(zhuǎn)凸輪型限位開關(guān)中，觸點被安裝在靜態(tài)支架上，用于操作觸點的凸輪安裝在轉(zhuǎn)軸上，凸輪的位置可調(diào)，轉(zhuǎn)軸通過傳動鏈條或齒輪機(jī)構(gòu)與啟動電動機(jī)實現(xiàn)機(jī)被耦合,因此，驅(qū)動電動機(jī)的轉(zhuǎn)動被傳遞給限位開關(guān)的轉(zhuǎn)軸，通過調(diào)節(jié)轉(zhuǎn)軸上凸輪的形狀和位置可以實現(xiàn)在所需的時間間隔觸發(fā)觸點。從機(jī)械角度講,驅(qū)動電動機(jī)的旋轉(zhuǎn)運動通過機(jī)械裝置被轉(zhuǎn)換為水平運動，由于限位開關(guān)凸輪軸的轉(zhuǎn)動與機(jī)械的平動成比例,所以,通過改變凸輪的位置可以調(diào)整機(jī)械的行程限制。與普通限位開關(guān)相比，旋轉(zhuǎn)凸輪式限位開關(guān)具有突出優(yōu)點,通過改變凸輪的位置可以在更大范圍內(nèi)輕松改變開關(guān)的觸發(fā)間隔和行程限制,然而，對于普通限位開關(guān)而言，一且行程限制確定后，只能通過調(diào)整杠桿位置對行程進(jìn)行小幅度的調(diào)節(jié)。然而，鏈條式旋轉(zhuǎn)限位開關(guān)的可靠性相對較低，因此，通常使用普通限位開關(guān)作為后備保護(hù)，以避免由于旋轉(zhuǎn)限位開關(guān)鏈條斷裂而失去作用，造成超程損壞。徐州閥門限位開關(guān)符號</p></p><br
