Passenger Elevator Industry Development Prospects
With the continuous progress of science and technology, the technical level and product quality of elevators are steadily increasing. The emergence of many new technologies and new products has greatly improved the use performance of elevators, such as machine-room-less elevators, gearless traction machines, permanent magnet synchronous drag technology, and remote monitoring technology, which have brought great convenience to our lives.
The speed of elevators is getting higher and higher, and super-high speed elevators have become the main focus of passenger elevator technological innovation in the future. In the 21st century, multi-purpose, full-function tower buildings will be developed, which greatly catalyzes the research process of ultra-high speed elevators. Among them, the study of traction ultra-high speed elevators continues to use super-capacity motors,
High performance microprocessors, vibration reduction technology, new roller guide shoes and safety gears, permanent magnet synchronous motors, car pressure relief and noise suppression systems, etc. Elevators driven by linear motors also have a lot of research space. The comfort of the ultra-high-speed elevator will be significantly improved in the future.
After the analysis of elevator-related mechanical principles, this paper deeply understands the application of theoretical knowledge of precision machinery manufacturing in actual production, and thus has more flexible control and grasp of book knowledge. Through the prospects for the development of the passenger elevator industry, we also have reason to believe that the future elevator will certainly provide more convenience for our lives.
Car: An elevator assembly that transports Passenger Elevator and goods is the working part of the passenger elevator. The car consists of a car frame and a car body. Door system: Its main function is to seal the landing entrance and car entrance. The door system consists of car doors, landing doors, door openers and door locks. Weight balance system: The main function is to relatively balance the weight of the car. In the elevator work, the weight difference between the car and the counterweight can be kept within the limit, so as to ensure the normal traction drive of the passenger elevator. The system is mainly composed of counterweights and weight compensation devices. Electric drive system: Provide power and implement elevator speed control. The electric drive system consists of a traction motor, a power supply system, a speed feedback device, and a motor speed controller.
