我厂生产的活塞体(见图1),材质ZL-104,其有效厚度为7mm。在0.7～0.8MPa装机试压过程中,因缩松渗漏废品率达75％左右。为此,我们组织技术攻关,采用水玻璃浸渗堵漏工艺,圆满地解决了这一难题。一、设备及操作程序1.设备(见图2)。2.抽真空加压浸渗方法的工艺流程:清洗零件→装罐→抽真空→放进渗剂→加压→取出并擦净零件→室温

I plant the piston body (see Figure 1), material ZL-104, the effective thickness of 7mm. In the 0.7 ~ 0.8MPa installed pressure test, due to shrinkage seepage rate of 75%. To this end, we organize technical research, the use of water glass impregnation plugging process, a successful solution to this problem. First, the equipment and operating procedures 1. Equipment (see Figure 2). 2. vacuum pumping process infiltration method: cleaning parts → canning → vacuum → into the seepage agent → pressure → remove and wipe parts → room temperature
