Elevators are electromechanical integrated equipment and large-scale electromechanical devices with a high degree of automation. Scientific maintenance can greatly extend the service life of elevators. Elevators, as precise and convenient modern tools, cannot be permanently worn out no matter how good their quality is. The safe and reliable operation of an elevator that has been installed, debugged, and inspected depends on the safety management, comprehensive maintenance, and reasonable use of the elevator by the user.Due to the characteristics of operation, normal wear and tear of equipment, aging of electrical appliances, and improper human use, elevators may all affect their performance. Therefore, it is said that "elevators are three parts in use and seven parts rely on maintenance". The maintenance of elevators is like that of small cars. Everyone knows that regular maintenance is necessary to ensure the safety performance of the car. Through professional elevator maintenance units or elevator manufacturing units, regular maintenance and upkeep of elevators can be carried out at regular intervals, which can promptly eliminate possible faults and ensure the safe use of elevators.
Elevators have been widely used in factories, warehouses, shopping centers, hotels, airports, stations, and many other places.
Due to the carrying capacity of the elevator, it is even more important to maintain it well, especially in the case of deflection after long-term operation. Usually, the elevator runs up and down along a basic vertical trajectory given by the steel wire rope. However, due to uneven distribution of personnel, the elevator's running trajectory will tilt slightly over time, and friction between the elevator body and the steel wire rope will occur during the operation of the elevator. Moreover, as time goes by, the friction increases, which can easily lead to safety failures. Therefore, it is particularly important to install tilt sensors on elevators, which can constantly detect the status of the elevator and ensure its safe operation.
Elevator vibration is a complex motion system with multiple factors working together, among which the vibration caused by the driving host is the main vibration source of the elevator. So the elevator drive host plays an important role in elevators, with the elevator drive host starting and braking, and rotating forward and backward up to 120 times per minute. The vibration signals of elevators are complex and may be caused by various factors such as electromagnetic, electrical, mechanical, or aerodynamic factors. Once a failure occurs in the driver host, the consequences will be unimaginable, and the cause of its vibration has become a widely concerned focus.
