Magnetic locks the two common problems

Magnetic lock design and electromagnet, when an electric current passes through the silicon steel sheet, tightly absorb electromagnetic lock will produce a powerful suction adsorption iron plate to achieve the effect of locking the door when you leave. What magnetic also can appear some problem, why sound great when magnetic locks shut the door? Why magnetic lock to use after a period of time, iron absorption not firm? Q: why magnetic lock closed sound great? Answer: a. Check whether there is a rubber gasket. b。 Check iron plate, screw is too loose. c。 Check whether the magnetic locks lock body and suction plate spacing is appropriate. Asked why 2: magnetic lock use after a period of time, iron absorption not firm? Answer: a. Check the power supply for a 'power and voltage' 1 a / 12 v / 24 v output is reduced. b。 To check whether there is foreign body (magnet surface Such as dirt, rust, foreign bodies, etc. ) 。 Magnetic locks appeared on the two problems above, there is a problem, we should solve this problem.
