摘要
节能是当今世界各种技术发展的趋势,本文针对液压电梯液压系统能耗严重的缺点详细比较了几种液压控制回路的特点,并针对某液压电梯液压控制阀的设计提出了改进方案。结果表明采用改进方案后总压力损失不到原方案的二分之一。闭式回路中的能量损失大为减小,减轻了闭式回路系统的发热。为液压电梯节能技术研究提供了启示。
Energy-saving technology is a development trend in the world today. As the hydraulic system of the hydraulic lift is energyintensive seriously, the paper detailedly compared several characteristics of the hydraulic control circuit and proposed improvement program for the design of hydraulic control valves. The results showed that the total loss of pressure of the improvement program was less than one half of the original proposal. It greatly reduced the energy and heating system loss of closed-loop . The article provided the inspiration for the research of Energy conservation of the hydraulic lift.
