產品詳情 Product details

欠速打滑開關是一種可靠性強、對軸轉速及其他旋轉裝置簡單通用的監測裝置。當監測到當前轉速信號低于正常轉速范圍開關輸出開關信號，以供報警或停機。無運動部件、無磨損、安全壽命長，一體化結構，集中的控制裝置，設定或故障檢修簡單。

2.工作原理
欠速打滑開關是為了檢測皮帶機尾輪的旋轉速度，開關與尾軸無接觸。當尾軸隨膠帶機運行旋轉時而帶動感應片，感應片與檢測器發生的感應信號輸入到控制電路中去。經放大，整形后進行計數，其計數值與預置數比較，從而判斷膠帶的速度，既:在達到低于打滑速度時執行電路輸出相應的開關信號，使主機停機。本開關可調整速度值。

3.設置
先按BET鍵出現數碼閃爍,再按■■鍵到顯示:1、2、3。再按BET鍵出現數碼閃爍，再按■鍵調整打滑轉數值，再按BET鍵設置成功。

4.使用與安裝
欠速打滑開關安裝在輸送機從動輪或其他能等于實際膠帶運行速度的轉軸側面，從動輪或轉軸側面需焊接一個可供欠速打滑開關感應面（感應面必須采用鐵質材料)，感應面截面尺寸不小于50mmx 50mm，欠速打滑開關與感應面最大距離為25mm。感應面為欠速打滑開關提供一個脈沖信號，從動輪旋轉一圈感應面通過一次欠速打滑開關區域從而產生一個脈沖信號。當產生一次脈沖信號時，欠速打滑開關面板上的脈沖指示燈會閃一次。需要確保除感應面外，從動輪側面無任何可使欠速打滑開關產生脈沖信號的金屬物體。當物體或撕裂的皮帶懸吊下來，掃落到航空鋼絲繩時，航空鋼絲繩拉動撕裂開關拉環使其動作，撕裂開關發出報警或停機信號。

5.主要技術參數

The underspeed slip switch is a highly reliable, simple and versatile monitoring device for shaft speed and other rotating devices.When it is detected that the current speed signal is lower than the normal speed range, the switch outputs a switch signal foralarm or shutdown.No moving parts, no wear, long safety life, integrated structure , centralized control device, simple setting ortroubleshooting.

2.Working Principle
The underspeed slip switch is used to detect the rotation speed of the tail wheel of the beltconveyor, and the switch has nocontact with the tail shaft.When the tail shaft rotates with the running of the belt conveyor, the induction piece is driven, and theinduction signals generated by the induction piece and the detector are input into the control circuit.Ater enlarging and reshaping.the count is compared with the preset number to judge the speed of the tape.That is, when the speed is lower than the slip speed,the execution circuit outputs the corresponding switch signal to stop the host.This switch can adjust the speed value.Theunderspeed slip switch is used to detect the rotation speed of the tail wheelof the beltconveyor, and the switch has no contact withthe tailshaft.When the tail shaft rotates with the running of the belt conveyor, the induction piece is driven,and the inductionsignals generated by the induction piece and the detector are input into the control circuit.Ater enlarging and reshaping, thecount is compared with the preset number to judge the speed of the tape.That is, when the speed is lower than the slip speed,the execution circuit outputs the corresponding switch signal to stop the host.This switch can adjust the speed value.

3.Options

First press the BET key to display the number flashing, then
press the .keys to display : 1,2,3.
Press the BET key again to make the number flash, and then
press the  key to adjust the slip rotation value.Press the
BET key again to set successfully.

4.Use & lnstallation
The underspeed skid switch is installed on the side of the driven wheel or other shaft of the conveyor which can be equal to theactual speed of the beltThe size of the Induction Cross section is not less than 50mmX 50mm, and the maximum distance betweenthe underspeed sliding switch and the induction surface is 25mm.The sensing surface provides a pulse signal for the under-speedslip switch, and the driven wheel rotates once through an under-speed slip switch area to generate a pulse signal.When a pulsesignal is generated, the pulse indicator on the underspeed sliding switch panel flashes once. lt is necessary to ensure that thereis no metallic object on the side of the driven wheel other than the sensing surface that would cause the underspeed slip switchto produce a pulse signal. When the object or torn beltis suspended and swept down to the aviation steel wire rope, the aviationsteel wire rope pulls the tear switch pull ring to make its action, the tear switch sends an alarm or stop signal.
