Elevator is the large and complex product of Electromechanical syncretic, mechanical part is equivalent to the person's body, electric equipment part is equivalent to the person's nerve. The high syncretic of machine and report, make elevator became the put together of modern science and technology and product. To the structure of elevator, traditional method is cent for mechanical part and electric part, but will describe with functional system, can mirror the characteristic of elevator more. Below the structure that introduces elevator machinery share simply, and our main purpose is how to control it.
One. Drag makes a system
The main function that drag makes a system is output and transfer power, make elevator moves. Drag brings a system to basically bring wire rope by drag, directive wheel, turn over stringy annulus composition.
2. Oriented system
The mobile freedom that directs main function of the system is limitative car and counterpoise is spent, make car and counterpoise can be made along slideway only litre fall motion. Oriented system is main by slideway, guide boots and slideway wear composition.
3. Car
Car is the elevator package that ships passenger and goods, it is the working section of elevator. Car is comprised by car wearing and car system.
4. Door system
The main function of door system is to seal a station entrance and car entrance. Door system by car door, layer door, door operator, door lock device is comprised.
5. Weight balances a system
Main function of the system is weight of relative balance car, can make in elevator job the weight difference between car and counterpoise maintains it is in limitation, it is normal that the drag that assures elevator makes drive. The system basically compensates device composition by counterpoise and weight.
6. Electric power procrastinates use a system
Electric power pulls the function that uses a system is to provide power, practice elevator speed control. Electric power procrastinates move a system to make motor by drag, power supply system, speed feedback device, the composition such as electromotor timing device.
7. Electric control system
The main function of electric control system is pair of elevator move execute operate and control. Electric control system is main by controller, positional display unit, dominate screen (ark) , make the same score a device, pick a layer implement wait for composition.
8. Safe protection system
Make sure elevator safety is used, prevent all accidents that endanger person security to happen. By limiter of speed, safe clamp, bumper, the protector that carry a station is comprised.
Of elevator procrastinate moved control system to experience from arrive simply complex process. Apply at elevator so far procrastinate move a system to basically have:
1. sheet, double fast AC motor procrastinates use a system.
Stator of 2. AC motor is pressure regulating timing procrastinates use a system.
3. dc dynamo - excitation of electromotor silicon controlled rectifier procrastinates use a system.
