Donghe RiverAuThe elevator suddenly opens the door and does not move after leveling, but automatically resumes operation after a few minutes: The elevator (escalator) has been running for too long, and the motor overheats. To prevent burning out, the motor cools down and automatically resumes operation.
In 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?
Donghe River.The door closing button has no self maintenance function. During the designated maintenance period, the elevator components in operation are inspected, refueled, dust is removed, and safety devices are debugged. Including non-destructive testing and maintenance of elevator traction steel wire ropes.

.2. Different types of civil engineering traction elevators, screw elevators, and hydraulic elevators have different requirements for civil engineering. Common traction elevators require a certain amount of hoistway space, which can be made of concrete, steel structure hoistways, and glass curtain walls to create sightseeing elevators; The depth of the pit should be at least 50cm or more; Additionally, there are certain requirements for the height of the top floor.
The braking system of the elevator is usually closed, which means it is in the braking state when there is no power, 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
When accidentally trapped in an elevator, one should remain calm, and call the elevator emergency rescue phone or community property phone for help. Do not open doors or mess with buttons and patiently wait for rescue.
If there is a reserved shaft in the villa residential area, the appropriate car model can be selected by comparing the width and depth of the elevator car based on the size, width, and depth of the shaft. If there is no reserved shaft, you can first choose the model of the elevator and create a new shaft based on the required reserved size space for different models.
Signal method& mdash; When passengers ride in elevators with electric storage devices, PCs, and microcomputers, they first need to give the elevator a call signal on the floor they are on. After entering the elevator car, they also need to register the floor signal they want to go to. These signals will continue to appear, and the elevator signal must continuously record and arrange the execution order. This is the signal or logic technology of elevators, which was early used with simple collective selection&flash& mdash; Relays, followed by the appearance of programmable devices&flash& mdash; PC machine. Nowadays, PCs are mostly used for freight elevators and escalators, while passenger elevators use microcomputer systems, which significantly improve reliability, anti-interference, and scheduling efficiency. Digital display of faults facilitates maintenance. Professional home elevator manufacturers and other products have a complete range of products that sell well both domestically and internationally.

build.Aircraft weighing tens or hundreds of tons in the elevator hangar are vertically lifted onto the airport runway
The elevator suddenly descends to the bottom floor and resumes normal operation: After the elevator is powered off and reconnected, the leveling reference position needs to be re determined.
These phenomena are not elevator malfunctions. When the elevator is fully loaded, the elevator car no longer responds to the next station's outbound call.
The elevator suddenly opens the door and does not move after leveling, but automatically resumes operation after a few minutes: The elevator (escalator) has been running for too long, the motor cools down and automatically resumes operation.
Quality risk.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,Donghe RiverHousehold duplex small elevator, and running smoothly.
Drive Method&# 8217& mdash; The advantages of worm gear traction machines and permanent magnet synchronous gearless traction machines compared to worm gear traction machines are: simple and compact structure, small volume, and light weight. Due to the fact that the permanent magnet synchronous traction machine is directly driven, without worm gear or worm drive, and without the stator coil that occupies a significant amount of space required for asynchronous motors, its main material is high energy density, high residual magnetic induction, and high coercive force neodymium iron boron. Its air gap magnetic density generally reaches over 0.75T so it can achieve small volume and light weight.

Donghe River.Will the elevator quickly fall during a power outage& mdash;& mdash; Some movies and TV dramas often mislead the public into thinking that if the elevator loses its power, it will lose control and engage in falling movements.
There are many similar situations in daily life, such as forcefully opening the door inside the car, causing the circuit to disconnect and forcing the elevator to stop, resulting in people being trapped. For example, if the elevator frequently enters and exits during decoration and falls into the crack of the door, the elevator hall door may not be tightly closed and after several consecutive doors are opened and closed, the elevator will stop.
