This instrument is designed and manufactured in accordance with the requirements of the Chinese standard GB/T 255 "Determination of Distillation Range of Petroleum Products" and the Chinese industry standard SH/T 0121 "Technical Conditions for Distillation Range Determination Equipment of Petroleum Products". It is suitable for determining the fraction composition of liquid fuels, solvent oils, and light petroleum products using the determination method specified in GB/T255 standard.
Main technical indicators and parameters
1. Working power supply: AC (220 ± 10%) V, 50Hz
2. Distillation flask: made of hard glass, heat-resistant above 500 ℃, with a ball diameter of Φ 69mm ± 1mm, a neck diameter of Φ 16mm ± 1mm, and a branch pipe and neck at an angle of 75 º ± 3 º.
3. Temperature gauge: -2 ℃~400 ℃, with a division of 1 ℃, in compliance with the requirements of the national standard GB/T 514.
4. Condensation tank: made of stainless steel material, length 180mm x width 100mm x height 150mm. Condensation tube,
Refine with a Φ 16mm × 1mm brass tube, with a smooth inner surface and a 15 degree inclination angle with the horizontal plane. If the length of the condenser tube is measured from the lower part of the outer surface, it should be 555mm ± 3mm. The outlet should be in a circular arc shape, and the height of the outlet joint should be no less than 10mm higher than the upper end of the condenser tube to ensure good cooling effect.
5. Heating regulation: It consists of a heating device, a thyristor temperature control circuit, and a control panel. The heating device consists of an electric furnace with a power of 1000W/220V and a continuously adjustable heating rate.
6. Measuring cylinder and pressure iron: Measuring cylinders of 100ml and 10ML. The pressure iron is made of stainless steel and does not rust in water. It is pressed on the base of the measuring cylinder and is sufficient to prevent the 100ml empty measuring cylinder from floating from the water in the glass cylinder.
7. Working environment: ambient temperature -10 ℃~+35 ℃; Relative humidity ≤ 85%.
8. Power consumption of the whole machine: not exceeding 1100W.
