摘　　要：我们研究了一种新型的油泵阀座翻边固定工艺,详细介绍了该工艺的实施方法以及它的四个基本过程,并且通过实际测试阀座翻边后的密封面宽度、阀座的保持力以及在不同压强下的泄漏结果来验证新工艺的效果。试验表明,该新型的翻边固定工艺能有效降低油泵的泄漏报废率,具有较好的工程应用前景。The paper studies a new crimp process of pump valve seat and introduces the operation method and four basic procedures in detail. The paper also verifies the effect of the new crimp process by lots of tests such as sealing area width measurement, valve seat crimp retention test and leakage teats with different pressure. All the results show the new crimp process has a good capacity to decrease the pump leakage rejection rate and has a good application prospect.
