国产输油泵现场试应用性能测试与分析

Performance test and analysis of domestic pump in field trial running

输油泵机组的鉴定验收测试项目包括性能测试、可靠性测试和噪音测试,在进行正式鉴定验收测试之前,先进行一次性能试应用测试,以便为下一步顺利完成正式验收测试提供建议和指导。以国内某站安装国产化泵测试为例,介绍了试应用站场的情况、国产输油主泵的技术特点以及性能测试方法、测试仪器与评价指标等情况。对2台相同参数的国产泵和国外泵性能测试结果进行对比分析,结果表明:两种测试流量下国产泵现场应用性能良好,电机耗电、泵效率、机组效率等主要参数接近国外产品先进水平,达到设计要求。针对测试中遇到的流量限制、振动偏大等问题提出了解决方法,对下一步鉴定验收测试给出了相关建议。

Acceptance test of pump unit includes performance test, reliability test and noise test. Before a formal acceptance test, a performance test is made on the pump in trial runnng, so as to provide a guidance to the next operations. Taking the domestic pump to be installed in a station as an example, this paper describes the station conditions and pump features, as well as the process, instruments and indicators of performance test. After comparing the domestic pump and a foreign pump with same parameters, it is found that the domestic pump has better performance in field application at two flowrates, with power consumption, pump efficiency, unit efficiency and other main parameters meeting the design requirements, which basically tally with advanced level of foreign products. Solutions are also raised to the problems of limited flowrate and severe vibration in the test, providing a-valuable reference to the next step of acceptance test.
