Elevator parts manufacturers tell you about several structural functions of the elevator
Passenger elevators are motor-powered vertical lifts with box-shaped pods for multi-story building passengers. A fixed lifting device that serves the specified floor. It has a car that runs between at least two columns of vertical rigid rails. The car is sized and structured to allow passengers to access or load cargo. It is customary to use the elevator as a general term for vertical transportation vehicles in buildings, regardless of the driving method.
The composition of the passenger elevator: traction system, guiding system, car, door system, electric drive system, electrical control system, safety protection system. The main function of the traction system is to output and transmit power to make the elevator run. The traction system is mainly composed of a traction machine, a traction wire rope, a guide wheel and a reverse rope wheel. Inverter system.
The main function of the guiding system is to limit the freedom of movement of the car and the counterweight so that the car and the counterweight can only move up and down along the guide rail. The guiding system is mainly composed of a guide rail, a guide shoe and a rail frame. The car is an elevator component that carries passengers and cargo and is the working part of the elevator. The car is composed of a car frame and a car body.
The main function of the door system is to seal the landing entrance and the car entrance. The door system consists of a car door, a landing door, a door opener, and a door lock device. Weight balance system: The main function of the system is to 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, and the traction drive of the elevator is guaranteed to be normal. The system consists mainly of counterweight and weight compensation devices. The function of the electric drive system is to 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 control device.
The main function of the electrical control system is to control and control the operation of the elevator. The electrical control system is mainly composed of an operating device, a position display device, a control panel (cabinet), a leveling device, a layer selection device and the like. Ensure the safe use of the elevator to prevent accidents that endanger personal safety. It consists of a speed limiter, a safety clamp, a buffer, and an end station protection device. The passenger elevator adopts the vector-controlled digital closed-loop VVVF inverter, which can accurately control the host's rotating torque in real time according to the actual load of the car, the uplink and downlink speed, and adjust the current magnitude and phase to ensure the smooth running of the elevator.
