Do not underestimate the small magnetic lock, as long as a little bit of the current electromagnetic lock will produce a great magnetic force, control the electromagnetic lock power supply access control system to identify the right personnel and then power off, the electromagnetic lock can lose the suction to open the door. It sounds amazing and woody. What is the principle of magnetic locks ? We will unveil it immediately.
[Magnetic lock principle]
The principle of magnetic lock (or electromagnetic lock) is the same as that of an electromagnet. It is the principle of using electro-magnetic, and then the opposite pole attracts. When the current passes through the silicon steel plate, the electromagnetic lock will generate a strong suction and hold it tightly. The iron plate reaches the effect of locking the door. As long as the small current electromagnetic lock will generate great magnetic force, the access control system that controls the electromagnetic lock power supply will identify the personnel and then turn off the power, and the electromagnetic lock will lose its suction to open the door. Because the electromagnetic lock has no complicated mechanical structure and the structure of the bolt, it is suitable for the access control of the escape door or the fire door. Its interior is protected by epoxy resin. At present, the suction strength of the electromagnetic lock is represented by LB (pounds), and the test method is static pressurization. The so-called static pressure is the electromagnetic lock gradually increases the tension on the adsorption iron plate after the energization, when the electromagnetic lock suction exceeds the moment when the absorption of iron plate, the tensile force data is the value of the electromagnetic lock pull. In addition, the force of the electromagnetic lock and the adsorbing iron plate must be face to face and a collinear load test, so that the holding force of the electromagnetic lock is the largest. The adsorption iron plate may be magnetized for a short period of time due to the magnetic induction of the electromagnet for a long time.
[Magnetic Lock Installation Steps]
The first step: first open the cover with a screwdriver, and then use the hex wrench to punch the board, ready to install the second step: take out the installation board, fold the board along the dotted line to put the board in the required lock position, and then put the need Holes are punched after punching.
third step:
A After the iron plate is fixed, insert the Allen screw into the iron plate, place the rubber washer between the two metal washers, and then set it on the Hexagon screw. Insert the iron plate into the three holes in the door and insert the mushroom head from the other side of the door. Use a hex wrench to lock the iron plate on the door.
B. Fixing of the side board, the side board is fixed to the previously punched door frame with the two round head screws (fixed in the long hole of the side board). Note: Do not lock the edge plate so that it can move forward and backward to facilitate the correction of the position.
C. Correct the position of the side board so that the side board and the heel board are properly positioned so that the lock body can be in close contact with the successor plate.
D After fixing the lock body and the side panel to lock the semicircular head screws of the side plates, lock all the countersunk screws, and then remove the semi-circular head screws and drill holes in place for wiring. Finally, use a hex wrench to lock the lock body on the side plate.
Step 4: Wire according to instructions in the instructions.
Step 5: Cover the cover and insert the small aluminum cylinder into the screw hole of the lock body.
[Magnetic Lock Installation Precautions]
Do not drill holes in the iron plate or the lock body; do not replace the iron plate fixing screws; do not wipe the electromagnetic lock with a stimulant; do not modify the circuit. Maintenance: The maintenance of the magnetic lock is relatively simple compared with other locks, as long as the surface of the iron plate and the lock body is kept free of impurities, so please wipe the surface with a non-corrosive cleaning agent on a regular basis.
When installing the iron plate, do not lock it so that it can sway slightly to facilitate the natural combination with the lock body.
Summary: The above is the magnetic lock principle and related knowledge collected by Xiaobian for everyone. I hope to help everyone! I believe we read the above article, have a certain understanding of the principle of magnetic lock it! If you want to learn more about this knowledge, please pay attention to this site information platform! Here are more things you want to know!
