Product Overview
MYDH-Ⅰ slip switch
These two speed detectors are used as a new type of device for detecting the belt speed of the conveyor, and real-time detection of the belt speed, which has been widely used on the belt in the conveyor system, and provides a reliable detection method for the safe operation of the belt conveyor.It needs to be installed horizontally on the conveyor bracket between the upward and downward tapes, so that the trolley and the surface of the tape have a certain pressure to prevent malfunctions caused by the trolley bounce. When the trolley wheel drives the inner pulse disc with the operation of the belt conveyor, the magnetic response signal of the sensor is input to the control circuit when the pulse disc rotates, amplified, and then counted. The count value is compared with the preset number to determine the belt speed of the tape, namely: normal speed, slipping or overspeed, etc. At the same time, the execution circuit outputs the corresponding switch signal.1. Structural features1. This machine is composed of trolley, pulse disc, electronic pulse switch, shell, etc. The trolley is made of cast iron, and the surface milling groove has a wear-resistant and slippery effect. The shell is made of aluminum casting and the joint is equipped with a sealing ring. Machine weight reduction and better waterproof performance;2. The switch inside the machine adopts normally closed type, if the belt speed is lower than 80% of the normal speed, it can trip or stop.

FAQ
Q1:Difference between normally closed and normally open tilt switch? A1:Normally closed is to switch on and off after tilting in vertical state, while normally open is to switch on after switching off tilt in vertical state.   Q2:The difference between manual reset and automatic reset? A2:Manual reset is to pull the rope switch action to continue to hold after release, need to reset device to restore, automatic reset is pull rope switch action release switch recovery.   Q3:Difference between unidirectional pulling rope and bidirectional pulling rope? A3:One way is to install the pull rope from one side of the switch, and the other way is to install the pull rope from both sides of the switch.   Q4:Is the action force of pull rope switch adjustable? A4:The required action force can be informed in advance and can be customized according to the requirements.
