產(chǎn)品詳情 Product details
1.概述
基于在運(yùn)輸機(jī)械、采石、發(fā)電、木材加工等行業(yè)預(yù)防事故的嚴(yán)格安全措施,使得安全拉線開(kāi)關(guān)的應(yīng)用也成為必要的技術(shù)。所謂危險(xiǎn)區(qū)域是指無(wú)安全保護(hù)裝置運(yùn)動(dòng)著的機(jī)器部件。與緊急按鈕開(kāi)關(guān)相比,可在拉線任何一處來(lái)動(dòng)作開(kāi)關(guān),從而實(shí)現(xiàn)安全保護(hù)作用。
2.工作原理
把檢測(cè)器掛在相應(yīng)的地方,當(dāng)物料升高或擠壓檢測(cè)器時(shí),使檢測(cè)器傾斜25°角以上,不管朝哪個(gè)方向傾斜,使檢測(cè)器斷開(kāi)。當(dāng)物料清除離開(kāi)時(shí),檢測(cè)器復(fù)位,保持常閉狀態(tài)。
3.應(yīng)用范圍
1、溜槽或轉(zhuǎn)接處堵塞探測(cè)。
2、輸送機(jī)屁帶跑偏探測(cè)。
3、翻車機(jī)卸料探測(cè)。
4、用于皮帶或振動(dòng)給料機(jī)有料或缺料探測(cè)。
4.產(chǎn)品特點(diǎn)
堅(jiān)固、抗腐蝕、安裝簡(jiǎn)便、控制裝置為印制電路板結(jié)構(gòu)??烧{(diào)延時(shí),防止誤動(dòng)作。標(biāo)準(zhǔn)外殼
20-43型→ExtAlx 20-38型-II類所有探頭均配有安裝附件,其性能已被世界上成千上萬(wàn)的應(yīng)用
5.主要技術(shù)參數(shù)


1.Features
Based on strict safety measures to prevent accidents in transportation machinery, quarrying, power generation, wood processingand other industries, the application of safety wire switches has become a necessary technology.The so-called hazardous arearefers to machine parts that are moving without safety protection devices.Compared with the emergency button switch, the switchcan be operated at any place of the cable to achieve safety protection.
2.Working Principle
Hang the detector in the corresponding place.When the material is raised or squeezed, make the detector tit more than 25° ,no matter which direction it is tlted, the detector will be disconnected.When the material is cleared and left, the detector resetsand remains normally closed.
3.Use & lnstallation
1.Blockage detection at chute or transition.
2.Conveyor fart deviation detection.
3.Unloading detection of dumper.
4.lt is used to detect the presence or absence of material onthe belt or vibration feeder.
4.Features
1.Rugged, corrosion-resistant, easy to install, the controldevice is a printed circuit board structure.
2.Adjustable delay to prevent malfunction.
3.All probes in standard housing Type 20-43- ↓ExtAlx 20-38-lIare equipped with mounting accessories.
