style="text-indent:25px">限位開關(guān)的應(yīng)用方面比較多，比較多電器里面都有它的身影。那這么簡單的開關(guān)能起什么作用呢？它主要是起連鎖保護(hù)的作用。較常見的例子莫過于其在洗衣機(jī)和錄音機(jī)（錄像機(jī)）中的應(yīng)用了。在洗衣機(jī)的脫水（甩干）過程中轉(zhuǎn)速比較高，如果此時有人由于疏忽打開洗衣機(jī)的門或蓋后，再把手伸進(jìn)去，比較容易對人造成傷害，為了避免這種事故的發(fā)生，在洗衣機(jī)的門或蓋上裝了個電接點(diǎn)，一旦有人開啟洗衣機(jī)的門或蓋時，就自動把電機(jī)斷電，甚至還要靠機(jī)械辦法聯(lián)動，使門或蓋一打開就立刻“剎車”，強(qiáng)迫轉(zhuǎn)動著的部件停下來，免得傷害人身。在錄音機(jī)和錄像機(jī)中，我們常常使用到快進(jìn)或者倒帶，磁帶急速地轉(zhuǎn)動，但是當(dāng)?shù)竭_(dá)磁帶的端點(diǎn)時會自動停下來。在這里行程開關(guān)又一次發(fā)揮了作用，不過這一次不是靠碰撞而是靠磁帶的張力的突然增大引起動作的。隔爆型限位開關(guān)注意事項：不使用的電源接口要用堵塞堵住。連云港閥門限位開關(guān)廠商</p><p style="text-indent:25px">機(jī)械式限位開關(guān)結(jié)構(gòu)簡單，成本低。連云港閥門限位開關(guān)廠商</p><p 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(yùn)動壓縮或吸進(jìn)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(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，在中途停止按壓微動開關(guān)輔助柱塞的行程。連云港閥門限位開關(guān)廠商</p></p><br /><p>文章來源地址:
