Nai meihengVerThe elevator stops on a certain floor for a long time without moving or responding to external calls: it is possible that the elevator administrator has activated the driver operation function.
The elevator stops on the first floor and the door does not move: the fire emergency landing function of the elevator is triggered by smoke or thermal sensors inside the building.
Nai meiheng.The safety monitoring machine room environment screen cabinet main power switch traction wheel speed limiter shaft and pit guide rail layer door and car counterweight should be reliably fixed with pressure plates to prevent loosening.
Passengers wearing long skirts and strapping sandals when riding on the escalator should try to stand slightly in the middle of the escalator to prevent shoes and clothing from being drawn into the escalator and causing danger, and to prevent skirts or pants from getting stuck.
.Aircraft weighing tens or hundreds of tons in the elevator hangar are vertically lifted onto the airport runway
Slide elevators are installed inside buildings and are often used parallel to buildings and sidewalks
Mine elevators are used for transporting personnel and goods in mines. Special elevators are designed for special environmental conditions, such as explosion-proof,Nai meihengScrew type household elevator, anti-corrosion, and heat-resistant elevators
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.
High transmission efficiency. Due to the use of permanent magnet synchronous motors for direct drive, the transmission efficiency can be improved by 20% -30%.
The elevator stops on the first floor and the door does not move: the fire emergency landing function of the elevator is triggered by smoke or thermal sensors inside the building.
Range.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.
Elevator does not close the door or repeatedly opens and closes the door: there are debris blocking the light curtain or door contact plate at the entrance or sill.
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,Nai meihengCustomized household small elevator, it will lose control and engage in falling movements.
Elevator does not close the door or repeatedly opens and closes the door: there are debris blocking the light curtain or door contact plate at the entrance or sill.
index.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.
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, allowing the elevator to have a low-speed operation process before the leveling brake, thereby reducing the impact of sudden deceleration during elevator leveling and improving passenger comfort. The advantages are fewer links and low failure probability,Nai meihengStage main lifting platform, 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.
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, and the motor overheats. To prevent burning out, the motor cools down and automatically resumes operation.
Nai meiheng.The gantry elevator is used in the door legs of large gantry cranes to transport workers and maintenance components inside the gantry crane
