Description

一种工程机械液压系统直动、先导溢流阀检测装置
技术领域：
本实用新型涉及一种工程机械液压系统直动、先导溢流阀检测装置。
背景技术：
溢流阀位于液压油箱内，检查溢流阀时需打开油箱盖，将油箱内的油放净，并且检查方法只是估计，并没有准确的检测方法，当溢流阀的开启压力过高时油管和泵易开裂，发生事故。
发明内容：
为了解决背景技术中存在的问题，本实用新型提供了一种工程机械液压系统直动、先导溢流阀检测装置，本装置能准确调试溢流阀的开启压力，并且体积小、携带方便、适用范围广泛、制造成本低廉。
本实用新型所采用的技术方案是：该工程机械液压系统直动、先导溢流阀检测装置包括储油罐，所述的储油罐通过低压油管与柱塞油泵的入口端密封连通，柱塞油泵的出口端安装有压力表，柱塞油泵的出口端通过高压油管与测试头密封连通，测试头连接有溢流阀。
本新型所具有的有益效果是：本新型能够对溢流阀开启压力进行准确调试，从而降低了机械运行风险，提高人身安全。本装置体积小、携带方便、适用机械及压力范围广泛、制造成本低廉。
附图说明：
图1是本实用新型的结构示意图。
图中：1-储油罐，2-低压油管，3-压力表，4-测试头，5-溢流阀，6-调节杆，7-柱塞油泵。
具体实施方式：
下面结合附图对本实用新型进一步说明：如附图1中所示，该工程机械液压系统直动、先导溢流阀检测装置包括储油罐1，储油罐1提供液压油，储油罐1提供的液压油经柱塞油泵7进行增压，储油罐1通过低压油管2与柱塞油泵7的入口端密封连通，柱塞油泵7的出口端安装有压力表3，溢流阀5内的压力通过压力表3读出，柱塞油泵7的出口端通过高压油管与测试头4密封连通，测试头4连接有溢流阀5，通过调整溢流阀5上的调节杆6来调整溢流阀5的开启压力在正常工作范围之内。
