一、问题的提出当前不断对产品质量及标准化提出要求,许多产品的零部件,特别是电器产品的零部件,国家标准都要求进行承受压力试验,并规定了详细的技术规范。如GB2797—81(灯头总技术条件)。其特点是压力范围在几千克至几十千克,精度要求较高。目前的商品压力试验机品种很多,但基本上是为适应建材,建筑构件,机械零部件的试验而设计的,压力试验范围往往以吨为单位,因而精度较低,而且价格昂贵,在几万元至几十万元之间,为了节省资金,按照国家标准进行严格承受压力试验,研制较小压力范围,精度能够满足要求的压力试验机是非常必要的。下面介绍为检验灯具承受压力试验(即
First, the issue raised Currently on the product quality and standardization requirements, many product components, especially parts and components of electrical products, national standards are required to withstand the pressure test, and provides detailed technical specifications. Such as GB2797-81 (lamp head total technical conditions). It is characterized by a pressure range of a few kilograms to tens of kilograms, higher accuracy requirements. The current product pressure tester a lot, but basically to adapt to building materials, building components, mechanical parts and the design of the test, the pressure test range is often in tons, and therefore less accurate and expensive, tens of thousands Yuan to hundreds of thousands of yuan, in order to save money, in accordance with national standards to withstand the pressure test rigorously, the development of a smaller pressure range, accuracy to meet the requirements of the pressure testing machine is very necessary. Described below to test the lamp withstand pressure test (ie
