1000L/min大流量液压实验台设计
DESIGN OF A HYDRAULIC TEST BENCH WITH 1000L/min FLOW
摘要
目前液压系统已经在航空航天、民用设等方面得到了非常广泛的运用。液压系统在对状态监测、故障诊断还有对液压元器件进行分析和检测技术也是一天天成熟起来。但在对大流量安全阀进行实验的技术,相较国外无论是技术上还是理论上都比较落后。和大流量安全阀发展的速度不能够成正比。国内对大流量安全阀的检测上,是没有这个技术的,也不可以进口先进的检测设备。所以,对其进行设计和研究是非常有必要的。
本次设计的题目是1000L/min大流量液压实验台设计,主要研究的对象是安全阀。本次设计的主要内容有:对液压传动的应用进行了解和掌握;对液压实验台的研究现状还有发展前景有了比较全面的认识。明确设计的步骤,本次检测的目的还有检测回路的确定等等。对电机、液压元件还有液压集成块进行选择、设计及确定。设定正确的测量条件,选择正确的测量方法,完成流量计的选择等。

Abstract
At present, the hydraulic system has been widely used in aerospace and civil settings. The hydraulic system is mature day by day in condition monitoring, fault diagnosis and hydraulic components analysis and detection. However, the technology of large flow safety valve is relatively backward in technology and theory. And the development speed of large flow safety valve can not be directly proportional to the speed. The detection of large flow safety valve in China is neither technical nor imported. Therefore, it is very necessary to design and research it.
The topic of this design is the design of 1000 liters of large flow hydraulic test stand. The main object of study is safety valve. The main contents of this design are as follows: the application of hydraulic transmission is understood and mastered, and the research status of the hydraulic test bench and the prospect of development have a more comprehensive understanding. Clear the design steps, the purpose of this test is the determination of the detection loop and so on. The motor, hydraulic components and hydraulic manifold blocks are selected, designed and determined. Set the correct measurement conditions, select the correct measurement method, and complete the choice of flowmeters.
