Magnetic heating stirrer|A magnetic stirrerA few precautions:

1When there is a malfunction in the electric mixer, it is not necessary to immediately take action. Instead, one should first inquire about the process and symptoms of the malfunction. For unfamiliar equipment, one should first familiarize themselves with the circuit principles and structural characteristics, and follow the corresponding rules. Before dismantling, it is necessary to fully familiarize oneself with the function, position, connection method, and relationship with other surrounding components of each electrical component. In the absence of an assembly diagram, sketches should be drawn and marked while dismantling.

2. The equipment should be checked for obvious cracks and defects first, and its maintenance history should be understoodMagnetic heating stirrerService life, etc., and then inspect the interior of the machine.It is necessary to eliminate the surrounding fault factors and determine that it is an internal fault before disassembling. Otherwise, blindly disassembling may cause the equipment to deteriorate over time.

3. Mechanical and Electrical: Electrical inspections should only be conducted after identifying the mechanical components. When checking for circuit faults, detection instruments should be used to locate the faulty area. After confirming that there are no poor contact faults, the operation relationship between the circuit and the machinery should be checked in a targeted manner to avoid misjudgment.

4. Static first, dynamic later:When the equipment is not powered on, check the quality of electrical equipment buttons, transformers, thermal relays, and fuses,A magnetic stirrerSo as to determine the location of the fault. Power on test, listen to its sound, measure parameters, determine faults, and then carry out maintenance. If it is impossible to distinguish the three-phase voltage value when the motor is in phase loss, one should listen to its sound and measure the relative ground voltage separately to determine which phase is missing.

5. Clean before repairing: For heavily polluted electrical equipment, clean its buttons, wiring points, and contact points first, and check if the external control keys are malfunctioning. Many faults are caused by dirt and conductive dust blocks.

6. Power supply before equipment: The failure rate of the power supply part accounts for a high proportion of the entire faulty equipment, so repairing the power supply first can often achieve twice the result with half the effort.

7. Fault first and then debugging: for electrical equipment with debugging and fault, the fault should be eliminated before debugging, and debugging must be carried out under the premise of electrical line speed.

8. First universal, then special:A magnetic stirrerMalfunctions caused by the quality of assembly parts or other equipment failures generally account for about 50% of common malfunctions. The special faults of electrical equipment are mostly soft faults, which require experience and instruments to measure and repair.

When we encounter damage to the electric mixer during the experiment, we should not be anxious and should calmly respond. Through the 8 points we have explained above, we should first determine the cause of the malfunction and then prescribe the right medicine, which will definitely achieve twice the result with half the effort. In addition, we should also pay attention to daily useA magnetic stirrerThe maintenance.
