一、概述标准金属量器作为燃油加油机的检定设备,平时在检定使用时存在以下问题:1.环境温度与检定介质温差超过10℃时,加油枪出口温度与量器内介质温度差异较大;2.使用玻璃温度计测量介质温度容易破损,且不易读数;3.大流量(45L/min~65L/min)检定时,不能一次完成注油,严重影响检定准确度。为了解决上述问题,河北海兴县顺达计量仪器厂经过多年试验,研制出双层内夹保温层检定加油机用
First, an overview Standard metal measuring device as a fuel tanker testing equipment, usually used in the verification of the following problems: 1. Ambient temperature and the test medium temperature difference of more than 10 ℃, the gun outlet temperature and the gauge medium temperature difference is large ; 2. The use of glass thermometer to measure the temperature of the medium is easily damaged, and difficult to read; 3. Large flow (45L / min ~ 65L / min) test can not be completed once the oil, seriously affecting the verification accuracy. In order to solve the above problems, Hebei Haixing Shunda Measuring Instruments Factory after years of testing, developed a sandwich double-layer insulation test tanker
