DongshengAutomIn daily life, elevators are a commonly used tool that brings us a lot of convenience. But how much do you know about the types and safety knowledge of elevators?

Dongsheng.Reduce the overall noise of the machine. Due to the absence of noise from bearings during high-speed operation of an asynchronous motor and the absence of noise from worm gear transmission, the overall noise can be reduced by 5-10db (A) Low energy consumption. From the working principle of permanent magnet synchronous motors, it can be seen that their excitation is achieved by permanent magnets, and there is no need for the stator to provide additional excitation current. Therefore, the power factor of elevators can reach a very high level. At the same time the rotor of the motor has no current and there is no problem of electronic loss. Generally, it reduces consumption by 45% -60% compared to asynchronous motors. Due to the lack of low efficiency and high energy consumption worm gear transmission pairs, energy consumption is further reduced.
When passengers are riding on the escalator, they may lose their balance and fall due to leaning against the skirt board on the side of the escalator, which does not move, but their feet move with the steps. Especially when carrying a lot of packages while taking the elevator, it is more likely to fall on the escalator due to the inability to hold the handrail properly. So, when riding on the escalator, we must stand firmly and support it well and do not lean against the skirt board on the side of the escalator.
.Elevator Tip 1: Why elevators can trap people? Every elevator door on each floor has a safety switch, which can trigger the elevator to shut down in case of any abnormality. The elevator getting stuck is actually when the system detects an abnormal signal and triggers a protective device like braking to stop.
When encountering abnormal elevator operation, you can call the repair hotline to consult with the maintenance personnel or inform the service center to handle it. Do not take unauthorized measures to avoid causing greater harm to the elevator or even causing casualties.
The braking system of the elevator is usually closed, and only when it needs to be turned on, will the power turn on the brakes. So as soon as there was a power outage, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally, it is cut off
Household elevators must be regularly maintained to confirm their safety and whether they can continue to operate, while also repairing any faults and hidden dangers found.
Dragging Method&ndash& mdash; AC dual speed, Low speed elevators with frequency modulation and speed regulation often use AC dual speed (AC -) It changes the number of poles of the electric motor to achieve speed regulation, thereby reducing the impact of sudden deceleration during elevator leveling and improving passenger comfort. The advantages are fewer links and low failure probability, while the main disadvantages are poor comfort. The straight elevator starts frequently, and the impact current during startup is too high, increasing power consumption. This type of elevator is now commonly used for freight elevators.
Overloaded elevators do not operate: The load of elevators is limited, and if they are overweight, they will alarm and generally cannot be started. Most passengers can also voluntarily exit.

Elevators are used to transport firefighters, passengers, and fire-fighting equipment in the event of a fire. They are used to transport frozen goods in large cold storage or refrigeration workshops. However, they need to meet the requirements of sealing the door leaves and guide rails at the moving parts. Professional household elevators, villa household elevators, and small household elevators have stable, safe, reliable, and maintenance free performance, and their technical level has reached the domestic level, while also repairing any faults and hidden dangers found.
As elevator people, let's talk about elevator and elevator safety knowledge: The elevators we currently use include box type passenger elevators, escalators, and dedicated cargo elevators. Dedicated cargo elevators are installed due to special needs, and we don't use many of them. Now, let's take a look at the safety knowledge of box type passenger elevators and escalators: When we take escalators, Be sure to follow the safety instructions when riding on the elevator. Do not crowd or play around, hold onto the elevator firmly, fasten your shoelaces, and avoid getting them caught up.

Electrical components are roughly divided into screens, electrical switches for each safety circuit, etc. It is the brain of the elevator and the central nervous system of the elevator. The movement, operation, and door opening and closing of the elevator are all controlled by it, so it must be treated as a top priority in daily maintenance work. Do not short circuit the elevator circuit inside the screen during work. When the elevator door system malfunctions, someone shorts the elevator door for convenience in order to find the fault. This is very dangerous, and there are many accidents when shorting the door. Why? If a person opens the hall door and extends their head inward the elevator happens to run up or down to this point, and the hall door is shorted, the elevator cannot stop, so an accident is highly likely to occur. So in our daily maintenance work, we must not short-circuit the safety circuit. If it is necessary to short-circuit, we must identify which safety component has a problem and which safety component needs to be shorted. Moreover, after maintenance or urgent repairs are completed, we must promptly remove the short-circuit wire.

The difference between home elevators and ordinary public elevators is that the focus of home elevators and ordinary public elevators is different, with some indicators significantly reduced. For example, the load capacity of home elevators does not exceed 400kg, which is much lower than that of ordinary public elevators. Home elevators do not need to consider the issue of passenger flow, and the lifting speed is slower, ensuring safety. The lifting speed is generally between 0.3 to 0.4m/s, and running smoothly.
