0 前言 目前,国内付油方式:主要采用杠杆机械秤计量,缺点是劳动强度大,工作环境差,工作效率低;容积式计量,主要是计量精度低,稳定性差,需要人工测量密度和温度进行核算,人为因素影响大。动态密度计量法和计算机配合,可以监视付油工作中的异常情况及各种主要参数。根据调研和论证,我们和哈工大电子厂合作,开发研制了FX—Z型微机控制自动付油计量系统,这一动态密度计量法,基本上克服了以上缺陷,既直观又准确是一代新的付油计量设备。1 主要技术指标 本系统是由微机控制器及附属显示部分,信号发生器,控制系统和泵管路系统四部分组成,主要技术指标是: 油品比重适用范围:700～950kg/m~3 油品温度适用范围:0℃～60℃ 系统精度适用范围:±3‰ 每次每路发油量:50～9999kg
0 Foreword At present, the domestic oil pay way: the main use of lever mechanical weighing, the disadvantage is the labor-intensive, poor working environment, low efficiency; volumetric metering, mainly low measurement accuracy, poor stability, the need for manual measurement of density and temperature Accounting, human factors have a great influence. Dynamic density metrology and computer cooperation, you can monitor the oil work in the abnormal situation and a variety of major parameters. According to the research and demonstration, we and the HIT Electronics Factory, developed a FX-Z microcomputer control automatic payment metering system, the dynamic density measurement method, basically overcome the above shortcomings, both intuitive and accurate is a new generation of pay Oil metering equipment. 1 The main technical indicators The system is composed of computer controller and ancillary display, signal generator, control system and pump piping system composed of four parts, the main technical indicators are: oil proportion of the scope of application: 700 ~ 950kg / m ~ 3 oil Product temperature range: 0 ℃ ~ 60 ℃ System accuracy Scope: ± 3 ‰ Each time each hair oil: 50 ~ 9999kg
