Check before running multipoint magnetic agitator

Multi-point magnetic agitator is mainly the use of magnetic substances repel and attract the principle, we believe that we have played with the magnet, the principle of the magnet is the same repulsive opposite attraction, magnetic agitator principle is the same. The device, which constantly changes the magnetic poles at each end of the base to make a pulsating machine mix and roll, mixes the material inside the magnetic agitator extremely well and is commonly used in industrial and chemical research.

When running the multi-point magnetic agitator, check whether the accessories are complete or not, and then install the 2 stanches at the bottom (fix them with a wrench) according to the sequence. Then install the connecting head and clamp the solution bottle. Check to see if the electrical fixture is secure. After installation, tighten and calibrate the mixing rod, insert the motor power plug into the speed regulating control box, and then connect the power supply, the speed can be adjusted according to demand.

In order to ensure the safety of equipment and operators, we need to pay attention to the following points when using multi-point magnetic agitator:

1. Multi-point magnetic agitator is necessary to be firmly grounded to ensure the safety of equipment and person.

2. When mixing, adjust the speed control button gradually. Too fast adjustment will make the mixing rotor jump out of the magnetic steel force. Should be agile to stop the knob, to be mixing child stop, gradually rise speed mixing, level by level safe rise speed.

3. If liquid falls on the aluminum plate outside the heating plate, it will corrode the plate surface or generate heat and gas, which will affect the heating element and the motor. Please turn off the power immediately to eliminate it.

4, at room temperature viscosity of the liquid, often poor heat transfer function, heat mixing, should not be rapid heating, to avoid the container rupture. Make full use of the constant temperature equipment, gradually step up the temperature, and the sensor element must be thrust into the outer water jacket.
