沈阳电梯厂注重技术进步和产品的更新换代,继八六年推出微机控制交流调速电梯之后,最近又开发研制出三种新产品:一、PC 控制交流调速电梯:此种电梯是在微机电梯的基础上开发的新产品,利用最可靠的可编程序控制器(简称 PC)取代大量中间继电器和时间继电器,实行电梯的逻辑控制,而其速度控制系统采用的都是全闭环的可控硅调压调速控制。由于整个运行过程都严格按照予先设计的理想速度曲线运行,故具有运行舒适,平层精度高等优。采用集选控制方 Shenyang Elevator Factory focus on technological progress and product upgrading, following the introduction of computer-controlled exchange speed elevator in 1986, recently developed three new products: First, the PC-controlled AC speed elevators: This elevator is in the microcomputer Elevator based on the development of new products, the use of the most reliable programmable logic controller (PC) to replace a large number of intermediate relays and time relays, the implementation of the elevator logic control, and its speed control system are all closed loop controllable Silicon regulator speed control. As the entire operation process in strict accordance with the ideal speed curve designed to run, it has a comfortable operation, leveling accuracy and other advantages.
