工程机械液压节能技术的现状及发展趋势

摘要：随着机械工程的发展，工程机械的种类、数量和质量也有了大幅度的提高，但是大量的工程机械运转消耗了大量资源的同时，也对环境造成比较严重的污染，如：排放的废弃物、施工中的噪音、粉尘和不充分燃烧对大气的污染等，这些污染对我们的居住环境和城市环境造成了不可估量的影响。所以“节约能源、保护环境”也成为了工程机械开发和大量使用节能技术和节能产品的源动力之一，而且大量的节能、环保技术也是今后工程机械发展的必然趋势，不可逆转。本文将着重介绍液压机节能技术在工程机械的应用现状和发展趋势，推动该项技术在工程机械中的广泛普及。

Abstract: with the development of the mechanical engineering, the type of engineering machinery, the quantity and the quality is the sharp increase, but a large number of engineering machinery operation consumed a lot of resources, but also on the environment caused by serious pollution, such as: the discharge of waste, noise, dust and in the construction of the incomplete combustion pollution of the atmosphere, which to our living environment pollution and urban environment caused the immeasurable influence. So “to save energy and protect the environment” has become the engineering machinery development and the use of energy saving technology and energy saving products one of the source, and a lot of the energy conservation, the environmental protection technology but also the future of the inevitable trend of the development of engineering machinery, irreversible. This article will mainly introduced in mechanical energy saving technology hydraulic presses the application situation and trend of development, promote the technology of engineering machinery widely available.

一、液压技术的发展

液压技术在十八世纪就已经有了实际运用，随后得到了广泛的使用和发展。在上世纪六十年代液压挖掘机已经开始运用恒功率泵，其作用就是充分运用柴油机的输出功率的同时还能使柴油机不会超过最大载荷。随后将恒功率的控制原理应用双泵系统，从而出现了多种多样的控制形式，例如：分功率控制和全功率控制。
