摘要
液压缸作为机械设备中实现多功能化和智能化的关键执行部件之一,在生产和使用中受介质液压油的压缩、热膨胀等特性影响,其最突出的质量难题是内泄漏在液压系统外部难以被直接检测和监测,影响了出厂效率和检测精确度。通过将传统内泄漏检测方法应用于液压缸和整机设备出厂检验,并优化检测试验要求及操作过程,如:液压油与载体自身温度范围、初始冲液速度、试验计时开始时间、试验开始和结束温度、试验中封闭液压油体积等,提高了出厂检验的精确度和效率,对实际使用操作具有一定的指导作用。
As one of the key actuators to achieve multi-functionality and intelligence in mechanical equipment,hydraulic cylinders are affected by the compression,thermal expansion and other characteristics of medium hydraulic oil in production and use,and its most prominent quality problem is that internal leakage is difficult to be directly detected and monitored outside the hydraulic system,which affects the factory efficiency and detection accuracy.In this paper,the test requirements and operation process of the traditional internal leakage detection method are optimized when applied to the factory inspection of hydraulic cylinders and equipment:the temperature range of the hydraulic oil and the carrier itself,the initial flushing speed,the start time of the test timing,the temperature at the beginning and end of the test,and the volume of the closed hydraulic oil in the test,etc.,which improves the accuracy and efficiency of the factory inspection and has a certain guiding role for the actual operation.
