本文介绍了在大扭矩液压马达和工程机械油缸研制中所设计并建造成功的一系列测试装置,集中论述了一个比较成熟的测试系统,包括基本原理、系统分析和测试方法上的特点。一、液动机测试装置的评价标准工程、矿山机械,船舶甲板机械以及重型、化工机械的液压化,促进了高压、大功率液动机的发展,从产品设计研究的需要出发或从保证产品质量的需要出发,都必须十分重视和加强产品的测试工作——产品的型式试验和出厂试验。因此,探索建造一个先 This paper presents a series of test devices designed and constructed successfully in the development of high torque hydraulic motors and construction machinery cylinders. The paper focuses on a more mature test system, including basic principle, system analysis and test methods. First, the hydraulic test equipment evaluation standards Engineering, mining machinery, ship deck machinery and heavy, chemical machinery, hydraulic, and promote the development of high-pressure, high-power hydraulic machine, starting from the needs of product design or research to ensure product quality Need to start, must attach great importance to and strengthen the product testing work - product type test and factory test. So, explore building a first
