自动分馏器是一种用于测定汽油、煤油、轻柴油及其他轻质透明油品或化工物品的初馏点、千点及馏程的自动装置。此装置的操作过程(从清洗至分馏)全系周期性连续操作,其测定与苏联国定法((?)OCT2177-48)相同。自动分馏器的操作原理如图所示,试油流经冷却器冷却后,再流入计量筒,在计量筒内由虹吸管把多余试油吸入收集器,留下100毫升的试油就流至烧瓶。然后烧瓶底部的加热器开始升温加热,试油的蒸气由冷凝器冶凝后滴入接受器。当第一滴馏出液滴落在自热电偶上时,温度记录针的记录纸开始转动,并记录烧
Automatic fractionator is used to determine the gasoline, kerosene, light diesel oil and other light and transparent oil or chemical products of the initial boiling point, thousands of points and distillation range of automatic devices. The operation of this unit, from cleaning to fractionation, was carried out on a continuous, continuous basis with the same procedure as the Soviet Union’s national law (?? OCT2177-48). Automatic Fractionator operation principle shown in Figure, the test oil flows through the cooler cooling, and then flow into the measuring cylinder, the measuring cylinder by the siphon pipe to the superfluous oil into the collector, leaving 100 ml of test oil flow to the flask . Then the bottom of the flask began to heat up the heating heater, the test of steam condensate from the condenser dripping into the receiver. When the first dropping liquid drops on the thermocouple, the temperature recording needle starts to rotate and the recording temperature
