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,

centrifugal extractor, check whether each joint and interface are sealed,
whether the sealing ring and sealing surface are effective,
thin 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,

rotovap, 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,
rotary

operation of molecular distillation. (This article comes from the network, if
