Product Description
Speed switch combines the advanced technology of sensor and the actual application of domestic speed sensor developed (also known as speed sensor, low speed switch, speed switch, slipping switch) This product is mainly used for belt conveyor, elevator, screw conveyor, grinder, crusher, pump, centrifugal dry fire machine, mixer and dust collector and other rotating equipment, the belt
slipping, belt break, jamming, slow rotation, dynamic shaft shear and overload, drive chain (belt) off and other mechanical failure can be dealt with in a timely manner, to protect the equipment to reduce losses.
Working principle:
The speed switch is equipped with internal delay circuit, which can adjust the internal delay according to the different rotational speeds of the driven shaft to protect the equipment, through the detection piece installed on the driven shaft, using the principle of electromagnetic induction to give the speed switch pulse signal (when the detection piece rotates to a distance of 4-8mm from the speed switch for a pulse), the moment of power on the speed switch through the series of relays to make the relay suction delay for the set number of seconds. If the speed switch is set at 8 sec, and the equipment rotates for less than 8 sec, the speed switch will have no action through the relay connected in series (the relay will remain in contact).
When the equipment rotates for more than 8 sec, the speed switch will think that it has jammed and blocked,and the relay connected in series will make the electric relay jump off (the relay will lose power) to protect the equipment.
Installation and use:
All drives, such as screw conveyors, elevators, belt conveyors, zipper machines, crushers, etc. should be installed at their driven shaft (end of the machine).
