Wang Xianhui;Liu Hongpeng;Zhang Jun;Liu Kun;Wang Chunbin;Grease Institute,Sinopec Lubricant Co.Ltd.;North Dalian Analytical Instrument Co.Ltd.;  
The composition and performance of shield machine grease were quite different from those of common grease. The existing instruments and test methods for measuring the sealing performance of common grease could not be used to measure the sealing performance of shield machine grease. For this purpose,a new type of waterproof sealing tester for shield machine grease had been developed,and the corresponding test method had been worked out. The new type of waterproof sealing tester for shield machine grease consisted of high pressure air source,parallel double pressure control device,test barrel and relief valve,etc. It had the characteristics of simple operation,short test time,small error and strong reliability. The new type of waterproof sealing tester for shield machine grease could provide the necessary detection means for the development and application of shield machine grease,and also played an active role in the development of the standard of shield machine grease in our country.(Charts3 Table1 References2)
