Heating magnetic agitator selection

Like other equipment, in order to ensure the use efficiency of heating magnetic stirrer and effectively improve the service life of heating magnetic stirrer, we need to carry out regular maintenance and maintenance, among which:

1. Clean the mixing shaft and check whether the rolling direction of the mixing shaft rotates clockwise and no rotation is allowed.

2. Check whether all inlet and outlet valves of the reactor are available. If there is any problem, it is necessary to deal with it in time.

3. Check whether there are cracks, deformation, bulge, perforation, corrosion, leakage and other scenes in the reactor body, whether the insulation, paint and other conditions are intact, whether there is a drop, burning.

4. Listen to whether the sound of reducer and motor is normal, and feel the starting temperature of reducer, motor, frame bearing and other parts.

5, check the safety valve, explosion-proof film, pressure gauge, thermometer and other safety equipment is accurate and sensitive to use, safety valve, pressure gauge is checked, and the lead seal is missing, the red line of the pressure gauge is right, explosion proof film is not inside leakage.

The maintenance of heating magnetic agitator should start from daily work, including,

1. Make sure the magnetic stirrer is not heated without water.

2. Before heating the magnetic agitator for operation, check whether it is grounded and ensure that the work can be carried out after completion.

3. In order not to damage the instrument, insulation materials are usually placed inside the instrument. Therefore, when we use the magnetic agitator for the second time, we will find white smoke and pungent smell.

4. There is an upper limit on the heating of the devices inside the magnetic agitator. Therefore, it must be taken into account when heating.

5. Heat the magnetic stirrer when you finish heating, remember to turn off the heat and wait a few minutes for the heat to dissipate before turning off the stirrer.

6, in the process of operation must be careful, do not be burned, because the general temperature is relatively high.

7, to ensure the dry operating environment, because in a humid environment, the instrument is prone to leakage of electricity and other phenomena, which is why the instrument must be grounded, if the instrument is very wet must be blown dry with hot air.
