一、概述 液压抽油机出厂前要进行试验,以保证出厂产品质量。对于一台新研制的样机更有必要进行试验,以便为修改和完善设计提供可靠的依据。对液压抽油机进行试验(包括性能试验和可靠性试验),主要考虑两个方面;一是试验过程的加载方法,二是有关性能参数的检测方法。对于第二点这里不作讨论,本文主要讨论试验过程的加载方法。 First, an overview Hydraulic pumping plant to be tested before leaving the factory to ensure the quality of manufactured products. It is more necessary to test a newly developed prototype in order to provide a reliable basis for modification and improvement of design. The hydraulic pumping unit for testing (including performance testing and reliability testing), the main consideration of two aspects; one is the loading process of the test process, and the other is the performance parameters of the test method. For the second point is not discussed here, this article focuses on the loading process of the test process.
