The LNEYA refrigeration heating temperature control system is used in the molecular distillation method. So, what should be paid attention to in the use of the molecular distillation method?
If the molecular distillation method fails to pump up the vacuum, check the joints, whether the interface is sealed, whether the sealing ring and the sealing surface are effective; whether the vacuum grease between the main shaft and the sealing ring is coated, whether the vacuum pump and its hose are leaking, whether there are glass parts The phenomenon of cracks, chipping, and damage. In the molecular distillation method, a layer of vacuum grease must be applied to each grinding port, sealing surface, sealing ring and joints before installation. Water must be added before the heating tank is energized. Dry heating without water is not allowed. Screw it into the safety hole to prevent damage to the flask. The glass parts should be handled with care and should be washed, wiped dry or dried before installation.
The heater of the molecular distillation method must be equipped with a safety valve. The steam pressure in the heater should not exceed 0.01Mpa. The safety valve should be checked frequently for malfunctions and should not be careless. In any case, the steam valve should be closed when the machine is stopped. When the molecular distillation method circulation pump stops running due to a failure, the steam must be shut off immediately, and the operation of the molecular distillation method pump needs to be checked frequently, whether the oil level is normal, and the amount of cooling water. Frequently observe the motor current and motor temperature of each device in the molecular distillation method. In the molecular distillation method, it is strictly forbidden to break any part of the material under any circumstances. The liquid level of the evaporator should be adjusted slowly, and the level of the evaporator should not be increased or decreased. When the working environment temperature of the equipment is below 0℃, the accumulated water in the equipment and its pipeline should be drained to avoid freezing damage or blocking the pipeline.
If the molecular distillation method is used improperly, it may cause certain failures in the molecular distillation method. Therefore, the operation of the molecular distillation method needs to pay attention to the above operations.
