一、手压盘试验器的手压盘和丝忏是用方形丝扣相连接,丝扣磨损很快,往往一套压水试漏器要备用2—3个手压盘。增加手压盘的强度,延长使用时间,一种方法是提高材料强度,另一种是增加手压盘的厚度,使丝扣增多,减少每个丝扣上所受的压力,我们采用了后一补方法:(图1) First, hand pressure plate tester hand pressure plate and wire rod is connected with a square screw, screw wear quickly, often a set of pressure water leak detector to spare 2-3 hand pressure plate. Increase the intensity of the hand pressure plate and prolong the use time. One method is to increase the material strength. The other is to increase the thickness of the hand pressure plate to increase the number of threads and reduce the pressure on each thread. We have adopted One supplement method: (Figure 1)
