当泵在自吸状态下，若进油管路漏气或系统中液压缸、单向阀、换向阀等有较大的泄漏，均会使压力升不上去。这需要找出漏气处，紧固、更换密封件，即可提高压力。溢流阀有故障或调整压力低，系统压力也上不去，应重新调整压力或检修溢流阀。如果液压泵的缸体与配流盘产生偏差造成大量泄漏，严重时，缸体可能破裂，则应重新研磨配合面或更换液压泵。

液压阀是液压系统重要组成部分，其功能设计不仅能够优化液压系统性能，下面武汉星兴达液压气动来告诉大家如何选择匹配的液压阀？
我们在选择时主要是为了达到最大程度上的匹配，考虑的因素有：1、连接方式；2、工作压力；3、流量规格；4、实际安装。在选择时最好选择一些通用产品，产品都属于标准系列。
一般液压阀的安装方式也是受到液压装置的整体结构形式影响的，一般有螺纹连接型方式、板式连接型方式和法兰连接型方式。液压系统简单的情况之下，使用的元件数量少，一般采用螺纹连接型方式。液压系统比较复杂而安装位置和空间也很有限的情况之下可以使用板式连接型方式。对于大口径的液压阀一般采用法兰连接型方式即可。
下面小编来告诉大家三种常见的液压阀在实际的选用工作之中要注意哪些？1、流量控制阀其主要就是用来控制执行元件的运动速度，因此要充分考虑到液压系统的整体工作状态。2、压力控制阀主要是用来控制液压系统的压力大小，防止系统因为压力过大导致出现过载现象。3、方向控制阀一般要根据液压系统的工作要求来进行选择，一般有单向控制阀、双向控制阀、三位换向阀等等。
