保持型拉繩開關(guān)DC110V YM-LD2E保持型拉繩開關(guān)DC110V YM-LD2E保持型拉繩開關(guān)DC110V YM-LD2E

拉繩開關(guān)分為手動(dòng)復(fù)位和自動(dòng)復(fù)位兩種，需要達(dá)到國(guó)家規(guī)定IP等級(jí)。 

自動(dòng)復(fù)位：動(dòng)作后后能自動(dòng)回到初始位置，可能會(huì)造成誤差啟動(dòng)。 

手動(dòng)復(fù)位：動(dòng)作后有自鎖裝置能保持在操作位置上，需要手動(dòng)操作復(fù)位手柄可使其返回初始位置。 

拉繩開關(guān)是帶式輸送機(jī)*的安全保護(hù)裝置，防止事故的擴(kuò)大而帶來重大損失。由于安裝方便,開關(guān)轉(zhuǎn)換可靠,在帶式運(yùn)輸現(xiàn)場(chǎng)得到廣泛的應(yīng)用。

拉繩開關(guān)由拉桿、復(fù)位柄、凸輪、鎖槽及微動(dòng)開關(guān)等組成。 

拉繩開關(guān)安裝于皮帶輸送機(jī)的兩側(cè)的機(jī)架上，用鋼絲繩沿著輸送機(jī)兩側(cè)把開關(guān)連接起來。當(dāng)輸送帶設(shè)備發(fā)生緊急事故時(shí)，在現(xiàn)場(chǎng)沿線任意處拉動(dòng)鋼絲繩，鋼絲繩牽動(dòng)驅(qū)動(dòng)臂旋轉(zhuǎn)，通過傳動(dòng)軸帶動(dòng)扭力彈簧使精密凸輪發(fā)生位移，驅(qū)動(dòng)微動(dòng)開關(guān)切斷控制線路，使得輸送機(jī)停止運(yùn)行。

　因?yàn)樗嬗行谐涕_關(guān)、微動(dòng)開關(guān)的特性。同時(shí)具有傳感性能、性能可靠、性能穩(wěn)定、頻率響應(yīng)和壽命長(zhǎng)、抗干擾能力強(qiáng)、防水、耐沖擊、耐腐蝕等特點(diǎn)。廣泛應(yīng)用于機(jī)械、礦山、紡織、印刷、化工、冶金、輕工、閥門、電力、鐵路、運(yùn)輸、水泥、港口等行業(yè)中使用的帶式輸送機(jī)系統(tǒng)。

　　拉開關(guān)可以用在一些企業(yè)，其實(shí)這個(gè)地方可能還沒有見過，其實(shí)一些在農(nóng)村地區(qū)還是用拉開關(guān)。雖然現(xiàn)在人很有錢，有些農(nóng)村地區(qū)仍在使用拉繩開關(guān)。
