AI Technical Summary
Technical Problem
[0003]在目前的静压试验方案中，关键参数二号密封注入压力设置不符合现场实际的运行状态，无法模拟验证主泵稳定运行时真实的工况；而且，现有的静压试验验证方法仅执行稳态试验，而主泵实际运行时系统扰动工况较多，且运行历史上出现过由于系统扰动导致密封异常的问题，因此，仅稳态试验无法模拟现场真实的扰动工况，无法验证二号密封在受到振动后的状态
Benefits of technology
[0056]实施本发明的主泵二号密封静压试验方法及装置，具有以下有益效果：包括以下步骤：在完成试验准备后，调整主泵的二号密封的试验参数和主泵的三号密封的试验参数，使二号密封的试验参数和三号密封的试验参数满足试验条件；执行一次静压试验，并记录一次静压的试验数据；根据一次静压的试验数据判断二号密封是否合格；若不合格，则判定二号密封不合格；若合格，则执行扰动操作试验；在完成扰动操作试验后，执行二次静压试验并记录二次静压的试验数据；根据一次静压的试验数据和二次静压的数据对二号密封进行验证。本发明可以模拟验证主泵稳定运行时真实的工况以及扰动工况，同时还可以验证二号密封扰动后的状态，实现对二号密封的密封状态的可靠验证。

Abstract
The application relates to a primary pump No. 2 seal static pressure test method and device, which comprises the following steps: after completing test preparation, adjusting test parameters of a No. 2 seal of a primary pump and test parameters of a No. 3 seal of the primary pump, so that the test parameters of the No. 2 seal and the test parameters of the No. 3 seal meet test conditions; executing a static pressure test and recording test data of a first static pressure; judging whether the No. 2 seal is qualified according to the test data of the first static pressure; if not qualified, determining that the No. 2 seal is unqualified; if qualified, executing a disturbance operation test; after completing the disturbance operation test, executing a second static pressure test and recording test data of a second static pressure; and verifying the No. 2 seal according to the test data of the first static pressure and the data of the second static pressure. The application can simulate and verify real working conditions and disturbance working conditions of the primary pump during stable operation, and can also verify the state of the No. 2 seal after disturbance, so that reliable verification of the sealing state of the No. 2 seal is realized.
