采用蓄能器的新型液压电梯节能控制系统

由于不采用配重，液压电梯的装机功率与能耗都超过普通曳引式电梯。本文介绍了液压电梯蓄能器节能方案原理的基础上，分析了液压电梯利用蓄能器节能的可能性。通过对所设计的利用蓄能器节能的液压电梯的实验运行结果的分析，简要地对液压电梯的芳能器节能方案进行了评估。结果表明，在楼层较低的液压电梯系统中，蓄能器节能方案能显著降低液压电梯的能耗。

New Hydraulic Elevator Control System Applying Pressure Accumulators

Without balance weights,the required power supply of hydraulic elevators are more than that of traction elevators.This paper analysis the energy saving possibilities with pressure accumulators based on the introduction to the principles of energy savings method of hydraulic elevators.After analysis of the experimental results of hydraulic elevators with pressure accumulators,the evaluation for the energy saving method is made.At last,all the conclusion show that the energy saving methods applying pressure accumulators can reduce the power losses remarkable when the travel of hydraulic elevators is low.
