１．工作油缸漏油 原因分析及处理方法。因选用粘度较小的油，油从油缸和活塞间渗漏，更换粘度较大的油即可消除，有的试验机因长期未使用，油缸里的Ｕ型皮圈干枯，刚使用时皮圈不能发挥作用，在这种情况下，该试验机用一段时间后即可正常。另外，油内含有杂质、铁屑等进入油缸 1. Cause Analysis and Treatment of Oil Leakage in Work Cylinder. Because of the choice of the viscosity of the oil, oil leakage from the cylinder and piston, replace the viscosity of the oil can be eliminated, and some test machine due to long-term unused, U-shaped cylinder in the cylinder dry, just use the apron Can not play a role, in this case, the test machine with a period of time can be normal. In addition, the oil contains impurities, iron filings into the cylinder
