Biographie Original title: Precautions for use of molecular distillation method In Wuxi Shengze refrigeration and heating temperature control system, it is used in molecular distillation method. Then, what should we pay attention to in the use of molecular distillation method? Can users understand clearly? If the molecular distillation method cannot be vacuumized,winterization filtration, check whether each joint and interface are sealed, whether the sealing ring and sealing surface are effective,wiped film distillation, whether the vacuum grease between the main shaft and the sealing ring is properly coated, whether there is air leakage in the vacuum pump and its hose, and whether there are cracks, molecular distillation systems ,thin film distillation, cracks and damages in the glass parts. Before installation, the ground mouth, sealing surface, sealing ring and joint of the molecular distillation method shall be coated with a layer of vacuum grease. Water must be added to the heating tank before it is powered on. Dry heating without water is not allowed. Screw it into the safety hole to prevent damage to the flask. Glass parts should be handled with care. They should be washed, dried or dried before installation. The heater of molecular distillation method must be equipped with a safety valve. The steam pressure in the heater shall not exceed 0.01 Mpa. The safety valve shall be checked frequently to see if there is any fault. Do not be careless. In any case, the steam valve shall be closed when the machine is stopped. When the molecular distillation circulating pump fails and stops running, the steam shall be shut down immediately, and the operation of the molecular distillation pump, whether the oil level is normal and the amount of cooling water shall be checked frequently. Regularly observe the motor current and motor temperature of each equipment in the molecular distillation method. It is strictly prohibited to cut off any part of the material in the molecular distillation method under any circumstances. The liquid level of the evaporator should be adjusted slowly and should not be too large or too small. When the ambient temperature of the equipment is below 0 ℃, the accumulated water in the equipment and its pipeline should be drained to avoid freezing or blocking the pipeline. If the molecular distillation method is used improperly, it may lead to certain failures of the molecular distillation method. Therefore,jacketed glass reactor, attention should be paid to the above operations in the operation of molecular distillation.
