缆道动力起动系统改造

缆道动力起动系统是水文电动缆道低压电控设备的综合。由于大多数水文缆道已建成使用多年,其电控设备年久失修、性能下降,需要更新换代,且在兴建时,有的整体结构性能不够合理,型式多样,功能也不尽完善,所遗留的技术难题长期得不到解决,给缆道的使用和维护造成的一定的困难。为了使各缆道电控系统尽可能的统一,我们结合各缆道的使用特点,定型设计了一种适用于生产和生活兼用的通用型低压电控系统。

The dynamic running law study on driving system of hydraulic winder

Dynamic running law of the hydraulic driving system decides the hoisting cage velocity curve in a hoisting cycle and is decided by the characteristic of the hydraulic driving system and by the operating speed of hoist driver. The paper studies the dynamic running law of hydraulic driving system, analyses the influence of driver operating speed on the dynamic running characteristic, and points out the reasonable driver operating speed to control the dynamic stress in rope and to reduce the oscillation of rope system.
