一种燃料胶质含量测定仪的设计

Design of the Tester of Gum Content in Fuel

针对燃料胶质含量过高会导致进气系统产生沉淀物,使进气阀发生粘结而引起不安全的问题,设计了一种测定燃料胶质含量的仪器。该测定仪符合GB/T 8019-2008和ASTM D381《燃料胶质含量测定法(喷射蒸发法)》标准的规定。测定仪由控制系统和蒸发浴组成,采用智能测控系统,可自动显示空气压力、流量、蒸发浴温度以及试样蒸发时间,并具有自动报警功能,无需人工调节。现场使用表明,该仪器性能可靠,操作方便,具有一定的推广价值。

High gum content in fuel may lead to the precipitates produce in intake system, thus unsafe condition may occur because the intake valve becomes bonding. Aiming at this problem, the tester of gum content in fuel which conform the regulations of GB/T 8019-2008 and ASTM D381 ＂Standard Test Method for Gum Content in Fuels by Jet Evaporation＂ has been designed. The instrument is composed of control system and evaporation bath; the design adopts intelligent measurement and control system; the air pressure, flow are displayed automatically, the temperature of evaporation bath is controlled and displayed automatically. The specimen evaporation time is displayed automatically with alarm function, manual regulation is unnecessary. The field operation indicates that the instrument is reliable; ease to operate and offers certain promoting value.
