Petroleum product distillation unit HZ-662 ASTM D86

for hydrocarbonssolventautomatic

The HZ-662 petroleum product distillation tester is designed and manufactured according to the GB/T6536-97 test method. Suitable for natural gasoline (stable light hydrocarbons), automotive gasoline, aviation gasoline, jet fuel, special boiling point solvents, naphtha, kerosene, diesel, gas oil, and similar petroleum products. The petroleum product distillation tester is composed of an automatic bath temperature control system, an automatic distillation temperature control system, a refrigeration system, an automatic liquid level automatic tracking system, and a safety protection system. The instrument adopts the whole machine multi-thread operation control, which makes the instrument realize the operation, control, calculation and display automation, which greatly improves the measurement intelligence and automation. The instrument adopts the fuzzy temperature control principle, and the Freon compressor is used to control the temperature of the refrigeration equipment, which can accurately and precisely control the temperature of the condenser tube and the receiving chamber. The temperature measurement system uses high-precision thermal resistance to accurately measure the steam temperature. The instrument adopts imported high-precision liquid level identification system, which can accurately measure the distillation volume, and the measurement accuracy reaches 0.1ml. - Power supply: AC220V ± 10% 50Hz - Heating power: 2KW - Refrigeration power: 0.5KW - Steam temperature measurement range: 0°C ~ 400°C - Electric furnace temperature measurement range: 0°C ~ 500°C - Refrigeration temperature range: 0°C ~ 100°C - Refrigeration control accuracy: ± 1°C - Temperature measurement accuracy: ± 0.1°C - Volume accuracy: ± 0.1ml - Fire alarm system: nitrogen fire PRECAUTIONS - Please read the manual carefully before use to avoid misoperation. - When the system automatically prompts an error, please follow the instructions step by step to troubleshoot. - Avoid sticking oil to the bottom of the flask, if necessary, wipe it dry with a rag, otherwise it may cause a fire. - The equipment has been calibrated before leaving the factory. Do not touch precision equipment such as photoelectricity during operation. - Please set the test parameters accurately, otherwise the test results may be unreliable. - Refrigeration equipment cannot be turned on continuously, and the interval between two uses is more than 10 minutes. - The instrument bath must be filled with medium before it can be powered on, otherwise the heater will be damaged. - If the instrument will not be used for a long time, the medium in the bath should be completely removed by using a liquid suction device, and the instrument should be wiped clean with a rag to avoid affecting the life of the instrument due to the presence of the medium. The next time you use it, be sure to fill it with media before using it. - For safety, the air nozzle at the rear of the machine can be connected to nitrogen or carbon dioxide gas source. For equipment without automatic fire extinguishing, if a fire occurs, turn off the power switch of the host and then press the fire button on the front panel of the host.
