技术领域 technical field
本实用新型涉及液体液位检测技术领域，具体的讲是一种液压泵液位测量监控装置。 The utility model relates to the technical field of liquid level detection, in particular to a hydraulic pump liquid level measurement and monitoring device.
背景技术 Background technique
液压系统是通过改变压强增大作用力，从而来驱动机械执行机构或设备驱动的动力系统，在现代工业十分重要，应用非常广泛。 The hydraulic system is a power system that drives mechanical actuators or equipment by increasing the force by changing the pressure. It is very important in modern industry and has a wide range of applications.
在实际使用中，由于液压管路液压系统结构问题，液压站工作环境的因素，或液压组件老化等等，使得液压站在工作中发生液压接头渗漏，液压油泄漏，油管爆裂，油缸渗漏和突发失效等严重影响液压站工作的问题。这些情况的发生，使得液压站液压油的快速流失，不仅产生很大的经济浪费，也影响着工作环境和生态环境，而且对液压泵本身的损坏也非常大，因此对液压站的液位监控对整个液压站的稳定可靠工作非常重要。一般在液压站上安装液位表，这个液位表有上限和下限，用来标识液压站油箱加入液压泵站的最大液压油油量和液压站稳定工作所需的最低油量。但是这种液位表不能提供及时的信息反馈，如果点检不到位或工作不仔细极，很有可能都是在液压油漏完后才能发现液压站不能正常工作，再进行报修。 In actual use, due to the structural problems of the hydraulic system of the hydraulic pipeline, the factors of the working environment of the hydraulic station, or the aging of the hydraulic components, etc., the hydraulic joint leakage, hydraulic oil leakage, oil pipe burst, and oil cylinder leakage occur in the hydraulic station during work. And sudden failure and other problems that seriously affect the work of the hydraulic station. The occurrence of these situations leads to the rapid loss of hydraulic oil in the hydraulic station, which not only produces a lot of economic waste, but also affects the working environment and ecological environment, and also causes great damage to the hydraulic pump itself. Therefore, the liquid level monitoring of the hydraulic station It is very important for the stable and reliable operation of the entire hydraulic station. Generally, a liquid level gauge is installed on the hydraulic station. This liquid level gauge has an upper limit and a lower limit, which are used to identify the maximum amount of hydraulic oil added to the hydraulic pump station and the minimum amount of oil required for the stable operation of the hydraulic station. However, this kind of liquid level gauge cannot provide timely information feedback. If the spot check is not in place or the work is not careful, it is very likely that the hydraulic station will not work normally until the hydraulic oil leaks, and then report for repair.
因此一种能够及时反映液压站液位实时信息的监控装置在实际应用中非常有意义。 Therefore, a monitoring device that can reflect the real-time information of the liquid level of the hydraulic station is very meaningful in practical application.
