Common Problems of Electromagnetic Locks and Electric Bolt Locks

Common questions about electromagnetic locks and electric bolt locks

Electric bolt locks are different from electromagnetic locks. The production process requirements of electric bolt locks are very strict, which is not something that ordinary groups can master. There are only a few companies in China that can do it well (for example: Jia'an Locks). But why are there so many brands of electric bolt locks on the market?

The reason is: one is the low price; the other is the application characteristics of electric bolt locks. Generally speaking, electric bolt locks that are not made through special processes and special materials will not have problems in the early stage of use. They are all tested before leaving the factory. The lock tongue is weak. They will use the method of reducing the rebound spring force of the lock tongue to complete the locking action of the electric lock plug. Of course, we will have a certain degree of concealment when we do not understand the working principle of the electric bolt lock. But we pick up the electric bolt lock and move it quietly. We will know that the rebound spring force of the lock tongue of many locks is very small, and problems will arise as the use time increases.

Electric bolt locks: generally used for glass doors, wooden doors, etc.

Advantages: hidden security, beautiful appearance, good security, not easy to be pried open and opened.

Disadvantages: It is hard to dig the lock hole when installing.

Common problems:

1. The problem that users often encounter is the phenomenon after magnetization: there is no power when starting, the lock tongue cannot move when it is half extended; the lock tongue cannot be retracted when unlocking.

2. The current is large, the temperature is high, the magnetic susceptibility is fast, and the service life will be shortened.

3. The national standard temperature for electrical appliances is 60 degrees. Excessive temperature may cause the risk of fire.

4. The standard voltage used by general products is 12V. Due to the unstable power quality, the line will be too long and the wire diameter will be too small. These will directly cause voltage reduction and current reduction, thereby affecting the normal service of the lock.

The design of the electromagnetic lock (or electromagnetic lock) of Ji'an Lock God is the same as that of an electromagnet. It uses the principle of electromagnetism. When the current passes through the silicon steel sheet, the electromagnetic lock will generate a strong suction force to tightly absorb the adsorption iron plate to achieve the effect of locking the door. Only a small current is needed for the electromagnetic lock to generate a huge magnetic force. When the access control system that controls the power supply of the electromagnetic lock recognizes the correct person, it will cut off the power, and the electromagnetic lock will lose its suction and the door can be opened. Since the electromagnetic lock does not have a complicated mechanical structure and the structure of the lock tongue, it is suitable for passage control of escape doors or fire doors. The lock body is protected by the injection of epoxy resin inside. At present, the suction strength of the electromagnetic lock is expressed in LB (pounds), and the inspection method is static pressure. The so-called static pressure is that the electromagnetic lock gradually increases the pulling force on the adsorption iron plate after the electromagnetic lock is powered on. When it exceeds the suction force of the electromagnetic lock, the adsorption iron plate is instantly opened. The data of this pulling force is the pulling force value of the electromagnetic lock. In addition, the force between the electromagnetic lock and the adsorption iron plate must be face to face and linearly pressurized, so that the suction force of the electromagnetic lock is the largest. The adsorption iron plate may be magnetized for a short time due to the long-term magnetic induction of the electromagnet.

Electromagnetic locks are generally used for wooden doors and fire doors.

Advantages: The function is relatively stable, and the repair rate will be lower than other electric locks. The device is convenient, no need to dig a keyhole, only a wiring groove is needed, and the lock body can be fixed with screws.

Disadvantages: It is usually installed on the top of the threshold outside the door, and the beauty is not as good as the electric bolt lock with hidden device. The price is similar to the electric bolt lock, and some are slightly higher
