一、前言根据我国机械密封行业技术发展的需要,为了开发机械密封新产品,评价现有产品的质量,开展机械密封研究工作,我所建立了第一套具有多种测试功能的机械密封高参数性能评价系统。该系统与国内现有试验台相比具有参数高、功能全、测试精度高、工况及试验范围广的特点。本文介绍该系统的流程、装置、测试功能和保证测试精度的措施,以及对某些测试功能的试验验证。 I. Introduction According to the technical development of China’s mechanical seal industry needs, in order to develop new products mechanical seal, evaluate the quality of existing products, to carry out mechanical seal research, I set up a first set of a variety of test features mechanical seal high parameters Performance evaluation system. The system compared with the existing domestic test bench with high parameters, full-featured, high precision test conditions and test a wide range of features. This article describes the system processes, devices, test functions and measures to ensure the accuracy of the test, as well as some test functions of the test validation.
