Detailed Product Description: | Evolution and status of elevator technology in the 1930s, AC induction motors because of its low price, ease of manufacture and maintenance is widely used in the elevator. By changing the number of pole pairs of the motor way to achieve the two-speed control requirements, escalator accessories to make drag simplify the system structure, Xiushan escalators, and reliability are increased. Currently the majority of our elevators are used in this AC two variable-speed drive control. DC drag lift early in development to pay a single, after the two-speed drag the 1930s with the development of high-rise buildings, people on the elevator rated speed increasing demand, resulting in a DC motor DC speed control drag The high-speed elevators. The system from the initial open loop, there is level, there are contacts to today's closed-loop control, stepless, non-contact control system. This is another elevator control technology progress. With the development of electronic technology, from the late 1960s to the early 1970s, he began to develop the application of AC variable speed AC motor drag it from the AC voltage speed to further the development VVVF system. With its outstanding energy savings within a certain range (≤4m / s) completely replace the DC drive system. It is currently developing technology, escalator brand, is considered a leap forward in technology drag lift. The rapid development of microelectronics technology allows for an elevator control microcomputer, it is a comprehensive alternative to the contact-relay control mode. So that the elevator drive control, the mall escalators, automatic scheduling control signal operation and reached a new level of home users with a number of options and recommendations ladder rational choice elevator products, for the healthy development of domestic elevator market has a positive meaning. Note the following aspects when consumers choose Elevator: first to choose the elevator brand, not blindly price-oriented, low prices, was not necessarily the United States; Second, actively with the manufacturer at the time of the purchase and installation of elevators energy and Installation party communication. The quality depends not only on the quality of the elevator the elevator itself, also depends on the elevator installation. So choose a strong technical installation side is also necessary; again, the elevator routine maintenance and maintenance is also very important and should listen to the recommendations of the manufacturer of elevator maintenance and service. Some manufacturers may require the use of elevators, maintenance and service training and guidance.
