Test was done on an atmospheric tester with power provided by a XY type triplex plunger pump. A synthetic core with ratio of cement to sand as 1:1.5 was used.
试验是在常压实验架上进行的，由XZ型三柱塞泵提供动力，岩心采用灰砂比1：1.5的自制岩心。
With MEC - B mechanical dynamic tester, was measured the movement of shedding and pump plunger on a water jet loom, analyzed and discussed their primary technical parameters. The result will be beneficial to the fabric productivity and quality.
