產品詳情 Product details
1.概述
本品適用于檢測帶式輸送機在運行中出現的膠帶與主滾筒之間的打滑,防止打滑所造成的惡性事故,該產品還適用于多條膠帶機聯鎖或停機。為膠帶機的安全運行提供可靠的檢測手段。
2.工作原理
本產品在工作過程中,剛接通電源時,延時10秒工作指示燈1和2均亮繼電器不動作,延時之后通過兩路光電傳感器檢測帶速信號,然后輸入控制箱內,經微電腦(CPU)顯示并計算得出實際的帶速送顯示器,同時與預置帶速進行比較,當帶速低于設定值,控制器顯示帶速,并使相對應的繼電器發出信號,同時對應的指示燈(紅色)亮,說明皮帶打滑;反之,當實際帶速高于設定值時,控制器進入正常工作,對應指示燈(綠色)亮。繼電器釋放。
3.使用與安裝
本產品的控制箱應安裝在膠帶機機架上或距監測頭較近的墻壁上(不能大于100米)傳感頭安裝在膠帶機下皮帶上面且皮帶運行比較平穩處。傳感頭安裝有兩種方式:一種是講傳感頭焊裝在膠帶機托輯支架橫梁下面,另外一種可以現場自行焊接40*40的角鋼做橫梁在角鋼中間處打兩孔( 16 ),孔間距見膠帶機托棍的間距,將此角鋼固定在托輯支架的螺栓上即可。
4.結構特點
1、先按SET鍵出現數碼閃爍,再按“<”“A”鍵到顯示9、1、2、3,再按SET鍵出現閃爍,再按“<”“*”鍵調整運行轉速值,再按SET鍵設置成功。
2、同樣按照以上步驟把顯示9、1、2、3,改為9、4、5、6,進行調整打滑I的轉速值。
3、同樣按照以上步驟把顯示9、1、2、3,改為9、7、8、9,進行調整打滑I的轉速值。(設備供電應與皮帶機同步。設備得電后八秒內如檢測不到一個信號示為打滑,反之檢測到一個信號進入正常啟動程序自適應。當帶速大于設定值時進入正常工作狀態。如須長期帶電,應在皮帶啟動時在程控室屏蔽設備觸點。)
(1)為保證檢測器的可靠工作,檢測器在接電時控制器只顯示帶速,不作任何處理,當皮帶運行到正常轉速時開始工作既延時工作。
所以不要接電后就檢測。
(2)檢測器內部檢測及控制線路全部采用集成電路,從而大大提高了檢測器的檢測精度及可靠性,但是在使用中必須在技術參數內
工作。
5.主要技術參數
1.Features
This product is suitable for detecting the slip between the belt and the main roller during the operation of the beltconveyor toprevent vicious accidents caused by the slip.Provide reliable detection methods for the safe operation of the belt conveyor.
2.Working Principle
During the working process, when the power is turned on, the working indicators 1 and 2 are turned on after a delay of 10 seconds.The relay does not operate. After the delay, the two speed sensors are used to detect the speed signal, and then input into thecontrol box.The microcomputer(CPU)displays and calculates the actual tape speed display, and compares it with the presettape speed. When the tape speed is lower than the set value, the controller displays the tape speed and causes the correspondingrelay to send a signal and correspondingly lf the indicator light (red) is on, the belt is slipping; otherwise, when the actual beltspeed is higher than the set value, the controller enters normal work, and the corresponding indicator light (green) is on.Therelay is released.
3.Use& lnstallation
lne control Dox or tnis proauct snoula De Installea on tne peltconveyor frame or on the wall near the monitoring head(not more than 100 meters).The sensor head is installed on thebelt under the belt conveyor and the belt runs relatively smoothly.There are two ways to install the sensor head: one is to weld thesensor head under the beam of the roller support of the belt conveyor,and the other can weld the 40 * 40 angle steel on the spot to makethe beam,and make two holes( 16) in the middle of the angle, thedistance between the holes is shown in the distance betweenthe rollers of the belt conveyor, and this angle steel can be fixedon the bolt of the roller support.
4.Options
1.Press the SET key first to display a digital flash, then press the " <" and "A " keys to display 9,1,2,3, and then press the SET keyto flash, then press the " <" and " A" keys to adjust the running speed.Press SETagain to set successfully.
2.Follow the above steps to display 9,1,2,3, change to 9,4,5,6 to adjust the speed of slip l .
3.Also follow the steps above to change the display 9,1,2,3 to 9,7,8,9 to adjust the speed of the slip l . (The power supply ofthe device should be synchronized with the belt conveyor.If no signal is detected within eight seconds after the device ispowered on, it indicates slipping, otherwise a signal is detected and enters the normal start-up procedure to adapt. When thebelt speed is greater than the set value, it enters the normal working state.If long-term electrification is required, shield thedevice contacts in the program control room when the belt starts.)
(1) In order to ensure the reliable operation of the detector, the controller only displays the belt speed when the detector isconnected to the power, and does not perform any processing.When the belt runs to the normal speed, it starts to work, whichis a delay.So don't test it after power on.
(2)The internal detection and control circuits of the detector are all integrated circuits, which greatly improves the detectionaccuracy and reliability of the detector, but it must work within the technical parameters during use.
This product is composed of a sensor head and a control box.The control box is composed of a circuit board, a panel, a display,a micro-touch switch and a terminal.
