The forced convection oven is mechanical equipment commonly
used in the laboratory to reduce the moisture of substances by using heat
energy. It is used to dry the substances and is common drying equipment in the laboratory.
The water in the material overflows by vaporization. The purpose of drying the
material is to use or further process the need. Hot air drying oven is used for
industrial and mining enterprises, laboratories, scientific research units such
as drying, baking wax, sterilization.
So how to maintain and use the drying oven?
1. users must read the operation manual and notice
carefully
2. use the drying oven, we must pay attention to the
conformity of all the power supply voltages. When using, the socket ground wire
of the power supply must be grounded according to the regulations of use to
ensure the safety of the machine and the user.
3. do not touch the drying oven by hand as an electrical
part of the left space or rinse with water with a wet rag wiping machine. When
repairing the drying oven, cut off the power cord.
4. samples put into the air circulation oven, pay attention
to check, flammable, volatile items can not be put into the drying oven for
drying. And the items placed should not be overloaded and too dense. It is
necessary to leave space for natural convection of air so that the moist air
can accelerate the overflow at the top of the dryer and can’t be placed without
material for drying.
5. the power cord of the lab oven should not be wound on
the metal material, do not imitate the high temperature or wet place, also
check the installation position of the heater electric heating wire, confirm
the normal use of the electric heating wire.
6. drying oven should regularly check whether the silver
contact of the temperature regulator is hairy or uneven. If so, the contact can
be sanded with gauze and then used and should be cleaned with a clean cloth
regularly to make it in good contact (note that the power supply must be cut
off). Do not impact metal pipes of indoor temperature regulators to avoid
affecting sensitivity.
7. After connecting to the power supply, set the
temperature to the required one, the temperature indicator light is on, the
temperature begins to rise, and the blower can be opened at the same time, and
the blower is running normally. When the temperature rises to a predetermined
temperature, the constant temperature indicator lights up and the temperature
controller automatically controls the temperature.
