比如,对于泵电动机全封闭式动力组合,通过采用降噪、隔声结构,并用专门材料做外壳,就可将噪声降至60 dB以下。又如,选择环保介质、水基介质和新型的“电流变”液体作为介质,都将优化系统性能,控制污染,扩大其应用场合。此外,能耗控制技术也越来越受到重视,因为这不仅意味着节约能源,降低损耗,而且能消除发热升温这个诱发液压系统故障的根本潜因,提高系统的工作可靠性和性能稳定性,更重要的是它可使冷却系统的必要性不断缩小。通过采用集成化回路和铸造流道以减少管道损失,减少非安全需要的溢流量,减少系统的节流损失等,以达到控制系统的能耗。
高压、高速是液压技术的发展方向之一,随着压力的提高,能耗控制将更加重要,已成为国际关注的焦点之一,相关的理论与实践也日趋成熟。
3 .机电液一体高度集成化
微电子技术的飞速发展,为液压技术的进步注人了新的活力。液压器件是机电一体化的重要接口器件,充分考虑到液压技术的特点,而开发研制出的集液压、电子、传感技术于一体的新产品及其组成系统,兼备了电气和液压技术的双重优势。如低耗高速(10 mA 以下响应时间在2 ms 以内)电磁铁及数字式电液器件,可作为直接接口的电液转换器。内藏位移传感器的液压缸用于高精度闭环控制时,可实现工况监视和长感功能。液电技术的融合使得液压技水的发展超出日身传统的科学领域,向着包括传动控制、检测在内的综合自动化技术方向发展。

For example, for the motive combination of the whole closing type of the pump electric motor, decline Zao and separate a structure through an adoption, counteract specialized material to do outer shell, can decline the Zao voice to the 60 dB as follows.Again such as, choose an environmental protection to lie quality, water Ji to lie quality and new"the electric current change" liquid conduct and actions lie quality, all will excellent turn system function, control a pollution, extend it applied situation.In addition can consume the control technique also is valued, because this not only means economy energy, lower to exhaust, but also cans remove to have fever to heat the basic Qian which inducts a liquid to press system breakdown because of, credibility and function stability of the work of exaltation system, more important it can make the necessity of cooling system continuously contract.Pass an adoption an integration to turn back track and foundry to flow a way with decrease piping loss, reduce not- safe need of overflow discharge, reduce reduce expenses of system loss etc. with attain control system of can consume.
The high pressure, high speed are a liquid to press one of the technical development directions, along with the exaltation of pressure, can consume a control will be getting more important, have become one of the focus of international concern, related theories and practice to also be gradually maturing.
3.the height integration of the machine electricity liquid integral whole turn
The micro-electronics technically flies to soon develop and pressed a technical progress to note a person new vitality for the liquid.The liquid presses a spare part is machine electricity the integral whole turn of the importance connect a people's spare part, full in consideration of the liquid presses a technical characteristics, but the development develop a gather of a liquid to press, electronics, spread a feeling technique to constitute system at the new product of integral whole and it, and had electricity and liquid to press technical dual advantage.Such as low consume high speed(the 10 mAs responds to time at the 2 mses as follows in) electromagnet and numerical type an electricity a liquid spare part, can conduct and actions directly connect an oscular electricity liquid a conversion a machine.Inside hide to move a liquid of spread the feeling machine to press an urn to used for high accuracy to shut a wreath control, can carry out work condition surveillance with long feeling function.The liquid gives or get an electric shock technical fusion to make a liquid to press the development of skill water to outrun the body traditional science realm in day, the facing includes to spread to move a control, examination at inside of comprehensive automation technique direction development.
