Magnetic stirring electric heating sleeve operation

The magnetic stirring electric heating sleeve is a new product developed for the use of laboratories in schools, factories and research institutes. The product is reliable in operation, simple in operation, reasonable in structure, and continuously adjustable in heating power.

Introduction of magnetic stirring electric heating sleeve operation method:

1. Place the stirrer and the flask containing the solution and the beaker on the heating mantle.

2. Turn on the heating control power supply, the power indicator light is on, the right rotation heating control knob, the heating control indicator lights up; the whole machine starts working.

3. Turn on the stirring control power supply, the power indicator light will be on, and the right rotation speed control knob will start to rotate. The adjustment speed is only needed for the experiment.

Magnetic stirring electric heating sleeve operation precautions:

1. In order to ensure the safe use of magnetic stirring electric heating sleeve, please use the grounding wire.

2. In order to extend the use of the magnetic stirring electric heating sleeve, all the magnetic stirrer motors have a fan heat dissipation function. Therefore, when heating experiments, especially high temperature heating tests, the instrument cannot be used for heating alone, and the motor should be rotated to rotate. Or medium speed rotation (or idling) to prevent motor and electrical appliances from being damaged by high temperature radiation. If the motor cannot start to rotate, it should be promptly found to be repaired by the dealer. Otherwise, it will not be damaged or lost due to the operation, and will not be responsible.

3. The temperature of the heating part of the magnetic stirring electric heating sleeve is high, so be careful when working to avoid burns.

4. When the high temperature heating is finished, please turn off the heating first, and then turn off the stirring after leaving the temperature for a few minutes.

5, there are wet hands, liquid spillage, or long-term leakage of electricity under the conditions of excessive humidity, should be dried in time or naturally dried before use, so as to avoid danger.

6. When using magnetic stirring electric heating sleeves, white smoke and odor appear in the sleeve. It is normal for the color to change from white to brown and then white. Because glass fiber contains oily and other compounds in the production process, it should be Put it in a ventilated place and use it after a few minutes.

7. When the electric heating sleeve of 3000ml or more is used, there is a 吱-吱 sound which is different in the structure of the furnace wire and related to the thyristor voltage regulation pulse signal, which can be used with confidence.

8. When the liquid overflows into the sleeve, please turn off the power quickly, put the electric heating sleeve in a ventilated place, and use it after drying to avoid danger of leakage or short circuit of electrical equipment.

9. When not in use for a long time, please store the electric heating sleeve in a dry and non-corrosive gas.

10. Please do not empty the stove for heating or dry burning.

11. When the ambient humidity is relatively large, inductive electricity may be transmitted to the outer casing through the insulation layer. Please use the grounding wire to avoid leakage and pay attention to ventilation.
