Coil of rail injection solenoid valve for CNG natural gas modification

Inductance coil is very common in our daily life and plays an important role in electronic equipment. Of course, the precautions for the use of inductance coil are also very important, and the precautions for the use of inductance coil will be discussed:

1. The inductance coil should be stored in a dry and constant temperature indoor environment, away from high temperature, humidity, dust and corrosion.

2. The inductance coil should be handled with care and not transported violently. When stored, it should be ultra-high and load-bearing.

3. Wear gloves to contact the electrode in the process of production and use, so as to prevent oil stains on the hands and always ensure the best welding conditions.

4. The assembly market should not excessively bend the electrodes and pins to make them exceed the pressure they can bear.

5. Electrodes and pins should be melted by solder wire and evenly covered on the circuit board to avoid virtual welding.

6. Packaging should be based on the shape characteristics of the inductor coil. Square, cylindrical, polygonal and irregular packaging should be small in size, well fixed, stable in storage, able to withstand impact and vibration, and meet the requirements of standardization.

7. When designing the inductance coil, avoid installing it near the edge of the circuit board.

8. When using electronic measuring instruments, the operating methods, steps and precautions of the instruments should be strictly observed.

9. Do not touch any exposed winding parts after installation.

Definition of inductance coil:

Inductor coil is made by winding insulated enameled wires around an insulating tube. The wires are insulated from each other, and the insulating tube can be hollow, and it can also contain iron core, magnetic powder core or other magnetic oxide cores. In electronic circuits, it is called inductance for short. It is expressed by L, with units of Henry (H), Milli Henry (mH) and Micro Henry (uH), and 1h = 10 3mh = 10 6UH.

The role of inductance coil:

The electrical characteristics of the induction coil are opposite to those of the capacitor, "blocking high frequency and passing low frequency". High-frequency signals will encounter great resistance when passing through the inductance coil, and it is difficult to pass; However, the resistance to low-frequency signals passing through it is relatively small, that is, low-frequency signals can pass through it easily. The resistance of the inductance coil to direct current is almost zero. The magnitude of mutual inductance depends on the degree to which the self-inductance of the inductor coil is coupled
