汽车发动机缸盖排气门密封质量检测装置设计

Design of Quality Inspection Device for Automobile Engine Cylinder Head Exhaust Valve Seal

设计了发动机缸盖生产线中排气系统气密性检测机构,检测原理和外界因素对检测值的影响,选择检测方法,比较水没式泄漏测试法,压降法,流量测量法。确定使用流量测量法检测排气端气密性检测装置。

In this paper, a leak detection system is designed for the cylinder head production line. The detection principle and the influence of external factors on the detection value are selected. The detection method is compared with the water leakage test method, the pressure drop method and the flow measurement method. The flow measurement method is used to determine the air tightness detection device for the exhaust end.
