摘要
工程机械中负流量控制节能方法已经得到成功的应用,但其进口主控制换向阀订货周期长,价格高,所以提出了一种以泵—液控换向阀—压力开关—先导阀—梭阀—国产多路换向阀为系统环节来实现负流量控制的简单方法,既可降低成本,缩短制造周期,又基本达到了节能控制的功能。简单负流量控制方法在整机无动作时,能让主泵排量减到最小,从而配合发动机怠速模式,起到降低油耗的作用。
The energy saving way of negative flow control for construction machinery has gotten successful application, but because of its main import control valve has long order cycle and high price, a kind of new way to pump liquid control reversing valve, pressure switch, pilot valve shuttle valve-homebred multi-way directional valve for the system was put forward to achieve a simple link negative flow control method, which can not only reduce the cost, shorten the manufacturing cycle, but also basically achieve the energy-saving control function. Negative flow control method in machine without action can make the main pump dis- placement reduced to the minimum, thereby matching engine idle mode, and reducing fuel consumption.
