USES and scope of application: The instrument is designed and manufactured in accordance with the requirements specified in the high vacuum distillation method for petroleum products with high boiling point range (SH/ to165-92), the industry standard of the People's Republic of China. Structural features: The apparatus is composed of distillation unit, condensing unit and vacuum decompression system. 1, the distillation device is composed of heating number rate control system and heating furnace elevator, heating number rate regulation circuit is the main component of the solid-state regulator, its installation is simple, easy to use, reliable performance, the output voltage directly displayed by the voltmeter, intuitive and easy to control. The observation window of the heat preservation cover of the heating chamber adopts the front opening type, which provides great convenience for the installation of the flask, the adjustment of the height of the furnace frame and the observation of the heating furnace. 2. The receiving measuring cylinder of the condensing device is inserted in the stainless steel bath (there is an observation window in front of it), with built-in lighting, heating pipe and temperature sensor. The temperature control of the bath is simple and intuitive with the intelligent instrument of numerical control digital display. 3. The vacuum and decompression system is composed of vacuum pressure gauge, pressure regulating valve, buffer bottle, vacuum pump and connecting pipe, etc. The connection is air-tight, and the pressure adjustment is easy to operate and observe. External vacuum pump, used for reducing pressure during instrument test. Mercury manometer is formed after the u-shaped vacuum manometer is injected with mercury, and the ruler below is used as the reading scale of mercury manometer. Main technical specifications and parameters: 1. Working power supply: AC220V 50Hz. 2. Heating power of distillation flask: 0 ~ 1000W continuously adjustable. 3. Bath heating power: 800W. 4, bath temperature control range: at room temperature to 90 ℃ 5. Temperature sensor: Pt100 platinum resistance. 6, bath temperature control mode: digital display temperature control meter automatic temperature control. 7, the temperature control precision: set temperature + / - 1 ℃. 8. Buffer tank volume: 1000ml. 9. Maximum residual pressure of vacuum pump: 2mm mercury column. 10. Bath light: LED energy-saving light. 11, instrument working conditions: temperature: 5 ~ 35 ℃, relative humidity: < 85%.
USES and scope of application: The instrument is designed and manufactured in accordance with the requirements specified in the high vacuum distillation method for petroleum products with high boiling point range (SH/ to165-92), the industry standard of the People's Republic of China.
