Do not dry - heat the electric stirring sleeve
Magnetic stirring electric generally there are two sets of temperature control way, is a kind of electric contact mercury JiKong temperature temperature, the other is by controlling temperature sensor (electric), in use process CLP contact mercury and sensors are at one end into the measurement of the liquid, the other end connected to the machine, in the process of temperature control, when the temperature of the liquid is lower than the set temperature, the heating plate heat, when the liquid temperature reaches the set temperature, then by the electric point mercury thermometer or sensor signals to the host magnetic stirrer, heating plate to stop heating, again when the temperature is lower than the set temperature, the heating plate of continue heating.
In order to further reduce the failure rate of the magnetic stirring electric sleeve, we should pay attention to the following points in the operation:
1. Do not use magnetic stirring electric heat sleeve for dry heating.
2. Magnetic electric stirring sleeve shall be well grounded.
3, * times of use, the board with white smoke and odor, belongs to the normal phenomenon, because the internal insulation materials in the production process contains oil and other compounds, should be placed in the ventilation place, a few minutes after the disappearance of normal use.
4. Since the heat resistance of the motor and magnet of the agitator is limited, the instrument cannot be used only for heating in the heating test, especially in the high temperature heating test. Please adjust the motor to the rotating or low-speed rotating state (idling) to prevent the motor, magnet and high temperature radiation from being damaged.
5. At the end of high temperature heating, please turn off the heating, and leave the remaining heat for a few minutes before turning it off and stirring.
6. The heating part has a high temperature, so care should be taken when working to avoid scalding.
7. If there is wet hand, liquid overflow or long-term exposure to excessive humidity, there may be inductive electricity transmitted to the shell through the insulation, please keep the grounding wire and pay attention to ventilation. In case of serious electric leakage, please do not use it again. Please put it in the sun to dry or put it in the oven to dry before using, so as to avoid danger.
8. If no power is found, please first check whether the right rear insurance needs to be replaced.
9. Please keep the instrument clean and keep it in a dry and non-corrosive place when you do not use the magnetic stirring electric heat sleeve for a long time.
