摘要：

为了降低电动叉车的能耗,提出了一种将变频容积调速和蓄能器节能技术相结合的新型电动叉车液压起升系统。在不同负载工况下, 对配置蓄能器的电动叉车液压起升系统与普通变频调速电动叉车液压起升系统的能耗进行了试验研究。试验结果表明,相比普通变频调速电动叉车液压起升系统,配置蓄能器的电动叉车液压起升系统的能量利用效率更高,节能效果明显,节能率最高可达20.35％,具有很好的工程应用价值。

Abstract:

In order to reduce the energy consumption of an electric forklift, a new hydraulic lifting system was proposed, which was based on a combination of the technologies of a VVVF control and hydraulic pressure accumulator. The energy consumption of the electric forklift hydraulic lifting system with pressure accumulators and the one of VVVF controlled electric forklift hydraulic lifting system without pressure accumulators were tested under different load working conditions. The results showed that the latter system has higher energy efficiency and remarkably saves energy compared with the former. The maximum energy saving rate of the latter system can reach 20.35％, and it has promising value in engineering applications.

Key words: energy saving, pressure accumulators, energy consumption, hydraulic lifting system, electric forklift
