common problem:
1. The problem that users often encounter is the phenomenon that occurs after magnetization:
1), no power at the start, the lock tongue can not move halfway;
2) When the lock is unlocked, the lock tongue will not retract.
2, the current is large, the temperature is high, the magnetic susceptibility is fast, and the service life will be shortened.
3. The national electrical standard temperature is 60 degrees. If the temperature is too high, there may be a danger 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 line diameter will be too small. These will directly cause the voltage drop and current to decrease, thus affecting the normal operation of the lock.
Why is the action of the electric lock slow?
At present, there are many types of electric mortise locks on the market. The sales prices are different and the quality is uneven. Which one is better?
From the work of the surface of the electric mortise lock, there are fine control of the workmanship, and the surface of the workmanship is rather rough. In our case, of course, we must choose the manufacturer's products with fine workmanship, because the technical level of the manufacturer can be seen from the surface workmanship, but Is the quality of the finished product on the surface good? Not necessarily.
The electric mortise lock is different from the magnetic lock. The manufacturing process of the electric mortise lock is very strict. It is not something that ordinary manufacturers can master. It can only be done well in China. But why is there a market for electric locks with multiple brands on the market? That is because: first, the price is low; second, the use characteristics of the electric lock are determined. Generally speaking, electric plugs that have not been specially crafted and manufactured with special materials are not problematic at the beginning of use. They are manufactured after inspection, and the bolts have no force. They will use the spring force of the bolt to reduce the springback. The method to achieve the locking action of the electric lock plug, of course, we do not understand the working principle of the electric plug lock, there will be some blindness, but everyone pick up the electric plug lock and move gently, try the lock tongue As you come out, you know that the lock Springs of many locks have a small spring force, and as the usage time is long, the problem comes.
First, the movement is slow, and the second is that the lock tongue does not come out. why?
Because the electric mortise lock works by using a magnetic coil to generate a magnetic field, the material requirements are very strict, and the general material can also generate a magnetic field, but the magnetic permeability is not high, so the electromagnetic coil generates a small magnetic force, and the locking action force is of course small. I have to use the method of reducing the spring force of the bolt to achieve the locking action of the electric lock. The spring force of the bolt rebound spring is opposite to the magnetic force generated by the electromagnetic coil. Only the electromagnetic coil generates a magnetic force enough to overcome the spring force of the bolt rebounding force, the bolt is released, the lock is locked, and the lock tongue is required to come out and retract. It must be crisp and neat, there should be no blockage, otherwise it will be unqualified; in addition, the material without special treatment will be easily magnetized in the electromagnetic field environment, resulting in residual magnetism. The longer the time, the larger the accumulation, the smaller the magnetic force, and therefore the electric plug. The lock action is getting slower and slower, and at the end it doesn't move, or the lock tongue can't get back. I believe that everyone has encountered this in the process of use.
Under normal circumstances, electric plugs that have not been subjected to special processes and use of special materials will appear to be slow and the tongues will not come out after half a year to one year of use. Therefore, I hope that when you buy electric locks, Be careful.
