BF-06B真空蒸馏测试

BF-06B Vacuum Distillation Tester1.Performance characteristicsSingle-chip control, digital display distillation temperature, automatically record and print the distillate temperature, with vacuum pumps, vacuum pressure gauge Maxwell. The instrument used color LCD screen display, touch screen operation, can store, query and print test records can be automatically converted to atmospheric vapor temperature equivalent temperature (AET), has a reasonable structure, convenient operation, stable performance, and good reproducibility , oil chemical industry, defense, power, scientific research, teaching, such as the oil sector an indispensable analytical instruments. 2.Applicable standardsBF-06B Vacuum Distillation Range Meter GB/T9168 national standards in accordance with ASTM D1160 and the design and manufacture, under normal pressure applied to the determination of possible decomposition of the oil distillation products and distillation properties of fractions. 3.Apparatus PrincipleIn 0.13 6.7 kPa (1mmHg 50mmHg) between the provisions of an accurate pressure control, with about one and a theoretical plate distillation of the fractionation unit sample, can be the beginning of boiling point, boiling point and the end of the volume percentage of the recovery and pressure the same temperature dependence of the curve. Based on the evaporation of liquid, heat to boiling, and steam export to a different volume percentage of the collection, can be isolated from the oil in the distillate boiling point range in different areas. Vacuum Distillation Range with the principle of atmospheric distillation process, is distilled at atmospheric pressure and heavy oil cracking products easily, so at a relatively low temperature distillation, the liquid surface molecules must reduce the energy of distillation is to reduce the external pressure , thereby reducing the boiling point of oil. According to a different kind of oil can be used to carry out the pressure of the distillation of heavy oil to ensure that the oil-like molecular structure of the stability of law. Namely, the use of vacuum distillation of hydrocarbon from the polymer so that the thermal decomposition of high temperature distillation to achieve the purpose. 4.Structural characteristics BF-06B process decompression meter run mainly by the vacuum control system, circulating water system, glass distillation unit, cold trap, composed of electronic control units, and with Michael's vacuum gauge, vacuum pumps and the use of tempered glass making anti - burst the door. Vacuum system: there are two large capacity vacuum tank pressure balance in order to ensure the stability of vacuum pressure. The use of high-quality vacuum control valve manual vacuum valve finishing with a small, easy to operate, good sealing can be fine-tuning and so on. Vacuum pressure gauge using a combination of Michael's vacuum, it is by the "U" pressure vacuum gauge and vacuum gauge measuring the composition of wheat. (See the use of modular vacuum gauge Mak's Manual) Recycled water systems: distillation system is used to provide cooling of the device, by the constant temperature water bath, heater, circulating pump and circulation piping of the water bath temperature can be 0 - 100 arbitrary settings. Cold trap: cold trap cooled with liquid cooling to keep the temperature below -40 , can be done with liquid nitrogen coolant. 1) fixed at the top of the condenser and vacuum system is used to the cold trap distillation recovery at the condenser cooling in the low boiling point component. 2) fixed at the temperature sensor and vacuum gauge between the cold trap is used to prevent the distillation of low boiling point when the vacuum component of pollution. Glass distillation unit, its structure is manufactured in accordance with the standards GB/T9168-1997 for high temperature vacuum device. Use, I should wipe all the grinding and high temperature vacuum grease coating. Electronic control unit is the core control equipment, mainly by the CPU Intelligent control systems, color LCD touch screen operating system, printing system and test records, as well as the executing agency and so on. 5.Technical parameters Working power: AC 220V ± 10% 50 HZ Input power: <3000W Ambient temperature: 5 35 Humidity: ≤ 85%, Flask with the highest melting temperature materials: 400 Temperature range: <450 Temperature measurement accuracy: ± 0.1 Condenser maximum temperature: 80 The largest amount of equipment like: 200ml Graduated cylinder to collect the maximum volume: 200ml Contact:Mobile:(0086)13942632309Tel:(0086)411-84754555-801Fax:(0086)411-84753759
