Product Description
The under-speed slip switch is a highly reliable, simple and versatile monitoring device for shaft speed and other rotating devices.When the current speed signal is monitored to be below the normal speed range the switch outputs a switch signal for alarm or shutdown. No moving parts, no wear and tear, long safety life, integrated struclure, centralized control device, easy to set or troubleshoot.
Working principle:
The under-speed slip switch is designed to detect the rotational speed of the belt machine tail pulley, and the switch has no contact with the tail shaf, When the tail shat rotates with the running of the tape machine and drives the sensing piece, the sensing signal occurring between the sensing piece and the detector is input to the control circuit.
After amplification and shaping, it is counted, and its count value is compared with the preset number, so as to judge the speed of the tape, both; when it reaches lower than the skidding speed,the execution circuit outouts the corresponding switch signal to stool the main machine.This switch can adjust the speed value.
Installation use:
The under-speed slip switch is installed on the side of the conveyor driven wheel or other shaft that can equal the actual tape running speed, the driven wheel or the side of the shaft needs to be welded with an inductive surface for the under-speed slip switch (the inductive surface must be made of iron), the cross-sectional size of the inductive surface is not less than 50mm'50mm, the maximum distance between the under-speed slip switch and the inductive surface is 25mm.
The inductor surface provides a pulse signal for the under-speed slip switch, and the driven wheel rotates once through the under-speed slip switch area to generate a pulse signal, When a pulse is generated, the pulse indicator on the under slip switch panel flashes once.
lt is important to ensure that there are no metal objects on the side of the driven pulley, other than the sensing surface, that could cause the under slip switch to generate a pulse signal, When an object or torn belt hanas down and sweeps down to the aerial wire rope, the aerial wire rope pulls on the tear switch pull ring causing it to actuate and the tear switch signals an alarm or shutdown.
Seeting:
First press BET key to show digital flashing, then press key to show: 1, 2, 3.
Press the BET key again to show the digital flashing, then press the key to adjust the value of slipping.
and then press the BET key to set successfully.
