叶片泵具有结构紧凑。输出流量均匀,运转平稳,噪声小等优点,所以在机床,各种加工流水线,自动线,注射机,液压机和部分工程机械中得到了非常广泛的应用。叶片泵最适用于用量较大的中等功率设备的液压系统。叶片泵有双作用式定量叶片泵和单作用式变量叶片泵两大类。

常见故障及其原因
排除方法
顶盖处螺丝松动,轴向间隙增大,容积效率下降
适当拧紧螺钉,保证间隙均匀、适当(间隙为0.04~0.07 mm)
个别叶片滑动不灵活
清洗。清洗后仍不灵活时,应单槽调配,使叶片
定子内表面磨损,叶片不能与定子内表面良好接触
定子内表面磨损一般在吸油腔处
配流盘端面磨损严重
更换
叶片与转子装反
使叶片倾角方向和转子的旋转方向一致
系统泄漏大
逐个元件检査泄漏,同时检查压力表是否被脏物堵塞
