随着液压工业的发展,液压机械越来越复杂、多样化。对复杂的液压系统,若采用大量管接头和管子连接,易造成管道污染,引起系统故障。还会因振动和冲击引起泄漏,降低效率,并且还会增大系统的体积;若采用液压集成块,使液压系统象电子系统那样把元件集成化,单元化,则可减少液压系统 With the development of hydraulic industry, hydraulic machinery is more and more complex and diversified. For complex hydraulic systems, if a large number of pipe joints and pipe connections, can easily lead to pipeline pollution, causing system failure. But also due to vibration and shock caused by leakage, reduce efficiency, but also increase the volume of the system; if the use of hydraulic manifold, the hydraulic system as electronic components that integrate components, you can reduce the hydraulic system
