馏程仪自动控制测试系统设计

柴油清净性不仅影响发动机的燃烧状况，还影响汽车尾气中污染物的种类和数量，因此对市售柴油的清净性进行快速有效的监管非常重要。利用柴油清净性快速模拟设备可实现柴油清净性的快速检测，需用待测油品的馏程测定结果指导清净性检测实验的参数设置。通过采用行走设备专用控制器，在软硬件方面对手动馏程仪进行改造和优化，可在温度检测、加热自控、温度修正、冷却控制和红外线液位检测方面实现自动化控制，减轻人为操作的工作量和误差，快速便捷地实现油品性能参数的监控，同时更适应车载环境。馏程仪自动控制功能的开发有助于更高效地开展柴油清净性市场监管。

Design of Automatic Control System for Distillation Range Determination Device

Diesel oil detergency can drastically influence the performance of diesel engine, which has a great effect on vehicle emissions. In order to control the diesel vehicles emission, it is necessary to supervise commercial diesel. Diesel detergency fast simulator can make the detergency evaluation easier, which is an important method to supervise diesel. Distillation range of diesel is the essential base parameter for detergency fast simulator to set working condition.Travelling controller is used to optimize distillation range determination device, which make the detergency detection more intelligent and more time saving. After optimization, distillation range determination device can automatically test and correct temperature, control heating and cooling, and test liquid level by infrared, etc. Therefore, it can reduce operator’s tasks and errors. These optimization designs make it more convenient to operate the detergency detector on mobile monitor vehicle, which is beneficial to supervise commercial diesel rapidly.
