在液压传动的机械设备中,有的液压执行元件在一个不长的工作周期內要求有一个或几个高压大流量的输出?杂谡庵止た?如何从技术经济指标的角度,特别是节能的意义上满足系统峰值流量和压力的要求,这是设计人员必须认真考虑的问题。解决这一问题的方法是泵、蓄能器联合供油。当系统所需的流量较小时,泵输出的油液一部分输向系统,而多余的部分输向蓄能器,把液压能储存起来;而在液压执行元件需要高压大流量的时候,蓄能器和泵一起向系统输油,满足执行元件的要求。这样泵的传动功率就可减少,对节省能耗和减少投资都有好处。
In hydraulically driven machinery and equipment, some hydraulic actuators require one or several high-pressure and large-flow outputs in a short period of operation. From the perspective of technical and economic indicators, in particular, energy-saving In the sense of meeting the demands of system peak flow and pressure, this is a problem that designers must seriously consider. The solution to this problem is the pump, accumulator joint fuel. When the system requires a small flow, the pump output part of the oil input system, and the excess part of the input to the accumulator, the hydraulic energy can be stored; and hydraulic actuators need high pressure and large flow, the accumulator Pump with the pump to the system to meet the requirements of the implementation of components. This pump drive power can be reduced, to save energy and reduce investment are good.
