使用二通插装阀的粉末制品液压机液压系统分析

控制上液压缸的液压阀采用了二通插装阀，

控制下液压缸的液压阀采用了滑阀。粉末制品液压机与普通液压机有所不同，下缸装有控制活塞高位置的限程机构，调节限程机构，可控制模具中的装料量。下缸带有中心缸，以满足不同制品的工艺要求。

由于主机各液压缸的大小和速度相差较大，所需流量也有较大差别，液压系统采用压力补偿轴向柱塞变量泵，可以根据负载的大小，自动变换泵输出的流量,以适应不同工作状态压力和流量的不同要求。液压控制阀采用了二通插装阀与滑阀混合使用，以发挥两种控制阀各自的优点。在液压系统中，上缸液压系统需要大流量,使用了二通插装阀，下缸液压系统需要小流量,使用滑阀，以降低成本。

液压传动是一种可达到传递动力、增加动力、改变速比等目的的传动方式。液压传动是以液体为工作介质，靠处于密闭容器内的液体静压力来传递力的传动方式，静压力的大小取决于负载，而负载速度的传递是按液体容积变化相等的原则进行的，其速度大小取决于流量；如果忽略损失，液压传动所传递的力与速度无关。

液压传动相比其他传统传动方式优势较为明显：1）功率重量比大，能以较轻的设备重量取得更大的力和转矩；2）惯性小，启动、制动迅速；3）无级调速，调速范围大，低速性能好；4）高响应速度；5）高负载刚度；6）可控性好，易于实现自动化，液压元件位臵可以根据设备需要进行调整。

液压传动已成为现代机械装备与机电产品的重要基础技术，在工业机械领域有着极为广泛的应用。液压系统的应用领域包括：工业生产（锻压机械、注塑机、机床、加工中心、机器人、矿山机械、包装机械等）、行走机械（工程机械、建筑机械、农业机械、汽车等）、航空航天、舰船（船舶及舰艇甲板机械、操作及控制系统）、海洋工程（海洋开发平台、海底钻探、水下作业等）。以国外为例，约95%的工程机械、90%的数控加工中心、95%的自动化生产线均采用液压传动。此外，根据工业机械设备使用的液压系统压力条件不同，可按其额定压力分为低压系统（<6.3MPa）、中压系统（6.3-10MPa）、中高压系统（10-20MPa）和高压系统（>20MPa）。
