在修理液压元件时,经常会遇到新密封圈装上去后就有渗油或严重漏油的情况。折下密封圈检查时就会发现密封圈已被划破、卡伤甚至撕裂了。原因是被工件上的毛刺(三角槽、斜孔、横孔上均有毛刺)划破了。解决的办法很简单,可用电器行业常用的透明薄膜(聚脂薄膜厚0.04mm)把工件表面和密封圈隔开。当密封圈套在管子或圆柱外表时,可用薄膜把工件包住,这样密封圈就不会碰伤,待密封圈套到规定的位置时,可将薄膜抽出,见图1。如果要把密封圈装进管子的内孔,也可用同样方法进行,见图2。此法还
When repairing hydraulic components, often encounter a new seal installed on the oil leakage or serious oil leakage situation. Break the seal inspection will find the seal has been scratched, card injury or even torn. The reason is the burr on the workpiece (triangular groove, oblique hole, horizontal hole on the burr) cut through. The solution is simple, available in the electrical industry commonly used transparent film (polyester film thickness 0.04mm) to the workpiece surface and the ring separated. When the seal set in the tube or cylindrical surface, the film can be used to wrap the workpiece, so that the seal will not bruise, until the seal set to the prescribed position, the film can be drawn out, see Figure 1. If you want to seal into the tube bore, can also be the same method, shown in Figure 2. This method is also
