The Research of Performance Test System of Seals in Hydraulic Support Column

In order to solve the problem that there is no appropriate testing method for the purchasing process of sealing washer in hydraulic support producing company at present, the author designed a test bed used to test the seal performance of hydraulic cylinder in the mine hydraulic support to provide database supports for purchasing sealing washer for hydraulic support manufacturers, by using the performance testing system of sealing washer worked upright column for hydraulic support. The introduction of the principles, constitutions and functions of the test bed will be shown in this paper. After a number of experiments, it is reflected by the practical applications that the test bed is operating stably, accurately and efficiently which could be used for testing sealing washer.
