產品(pin)詳情 Product details

1.概述
在(zai)輸(shu)送(song)帶(dai)出(chu)現撕(si)裂(lie)(lie)、戳(chuo)破、交(jiao)界(jie)處損壞或(huo)(huo)銳利物(wu)(wu)凸出(chu)時(shi)，撕(si)裂(lie)(lie)開關(guan)(guan)能給監視(shi)人(ren)員(yuan)提供報(bao)警(jing)信號或(huo)(huo)關(guan)(guan)閉(bi)輸(shu)送(song)機。撕(si)裂(lie)(lie)開關(guan)(guan)成對安裝在(zai)傳(chuan)送(song)帶(dai)兩側，由兩段乙烯外套的航(hang)空(kong)(kong)鋼絲(si)(si)繩(sheng)連(lian)(lian)接起來。航(hang)空(kong)(kong)鋼絲(si)(si)繩(sheng)的一(yi)端(duan)固定(ding)在(zai)支撐托架上;另一(yi)端(duan)連(lian)(lian)接在(zai)撕(si)裂(lie)(lie)開關(guan)(guan)的拉(la)環(huan)，兩段航(hang)空(kong)(kong)鋼絲(si)(si)繩(sheng)在(zai)傳(chuan)送(song)帶(dai)下形成一(yi)個監控面，當物(wu)(wu)體或(huo)(huo)撕(si)裂(lie)(lie)的皮帶(dai)懸吊下來，掃(sao)落到航(hang)空(kong)(kong)鋼絲(si)(si)繩(sheng)時(shi)，航(hang)空(kong)(kong)鋼絲(si)(si)繩(sheng)拉(la)動撕(si)裂(lie)(lie)開關(guan)(guan)拉(la)環(huan)使其動作(zuo),撕(si)裂(lie)(lie)開關(guan)(guan)發出(chu)報(bao)警(jing)或(huo)(huo)停機信號。

2.工作原理
當膠帶運輸現場(chang)發生緊急事(shi)故時，拉動系在(zai)吊耳上的(de)航空鋼絲繩，使機內的(de)滑塊與開關作用，發出停機信號。松開鋼絲繩后，開關自動復位。

3.使用與安裝
1、開關(guan)平衡地安裝在機(ji)架固定支架上(shang)。
2、將(jiang)開關以對(dui)的形式安裝(zhuang)在膠帶兩側，用鋼(gang)絲繩將(jiang)兩個開關拉(la)環連(lian)接，并用吊環使鋼絲繩(sheng)的走式(shi)與膠帶平行(xing)。
3、拉繩動作應(ying)適(shi)宜，以(yi)確保開關可靠復位。一(yi)條膠帶可安裝多對開關。
4、安裝(zhuang)支(zhi)架不隨(sui)開關提供,需另購買。

4.主要技術參數

When the belt is torn, punctured,damaged at the junction, or a sharp object is protruding, the tear switch can provide an alarmsignal to the monitor or shut down the conveyor.Tear switches are installed in pairs on both sides of the conveyor belt and areconnected by two pieces of vinyl-coated aviation wire rope.One end of the aerial wire rope is fixed on the support bracket. Theother end is connected to the pull ring of the tear switch. The two sections of the aviation wire rope form a monitoring surfaceunder the conveyor belt.When the object or the torn belt is suspended and swept down to the aviation wire rope, the aviationwire rope pulls the tear switch pull ring During its action, the tear switch sends out an alarm or stop signal.

2.Working Principle
When an emergency occurs at the tape transportation site, the aviation wire rope attached to the lifting lug is pulled to make theslider and switch in the machine act and send out a stop signal.After loosening the wire rope, the switch is automatically reset.

3.Use& Installation

1 .The switch is installed on the rack fixing bracket in a balancedmanner.

2.Install the switches in pairs on both sides of the tape, connectthe two switch pull rings with a wire rope, and use the liftingring to make the wire rope run parallel to the tape.
3.The action of pulling the rope should be appropriate to ensurethe reliable reset of the switch. Multiple pairs of switches canbe mounted on a single piece of tape.
4.The mounting bracket is not provided with the switch and mustbe purchased separately.
