摘　　要：使用气压和真空相互结合的方法代替传统使用制动液的方法对制动主缸的密封性进行检测,检测方法包括动态真空密封性检测、静态真空密封性检测和静态气压密封性检测,不管是补偿孔式制动主缸,还是中心阀式制动主缸,或者是柱塞式制动主缸通过这三项检测后得到的检测效果更精准更全面,无任何后处理程序,比较适合在生产线上实际使用。The use of a combination of air pressure and vacuum to replace the traditional method of using brake fluid to detect the seal of the brake master cylinder. Detection methods include dynamic vacuum seal test, static vacuum seal test and static air seal test, whether it is a compensated hole brake master cylinder, a center valve brake master cylinder, or a plunger brake master cylinder. The test results obtained after these three tests are more accurate and comprehensive, without any post-processing procedures, and are more suitable for practical use on the production line.
