SBFEC Type DMF Series 13.5mm Hole Dust Collector Pulse Jet Valve Coil

SBFEC Type DMF Series 13.5mm Hole Dust Collector Pulse Jet Valve Coil

The connection mode of the solenoid coil can be divided into a lead type and a pin type.

First, the solenoid coil connection method:

1. Lead type: The electromagnetic coil lead type connection method can be divided into electric wires, two-core cables and three-core cables.

2. Pin type: pin type can be divided into three plugs (DIN43650A, DIN43650B, DIN43650C, or customized), two plug or custom-made form.

Second, the insulation level of the solenoid coil:

1. Insulation material grade: 130 (B) Temperature rise ≤ 85 ° C

2. Insulation material grade: 155 (F) temperature rise ≤ 115 ° C

3. Insulation material grade: 180 (H) temperature rise ≤ 140 ° C

4. Insulation material grade: 200 (N) temperature rise ≤ 160 ° C

How to improve the Q value of the wound solenoid coil?

The quality factor Q is a weight parameter that reflects the quality of the coil. Increasing the Q value of the coil is one of the important points that must be paid attention to when winding the electromagnetic coil. So, how to improve the Q value of the electromagnetic coil? Let me introduce you in detail below.

According to the working frequency, the wire of the coil is selected. Inductors with short working and low frequency are usually fired with insulated wires such as enameled wires. The operating frequency is higher than tens of thousands of Hz, and in the circuit below 2MHz, the multi-strand insulated wire is used to wind the electromagnetic coil, which can effectively increase the surface area of ​​the conductor, so that the Q value is higher than the coil wound by the single wire of the same cross-sectional area. About 30%.

Use a high quality coil bobbin to reduce media loss. In high frequency applications, such as short-wavelength bands, due to the common coil bobbin, the dielectric loss is high. Therefore, high-frequency dielectric materials such as high-frequency ceramics, polytetrafluoroethylene, polystyrene, etc. should be used as the skeleton, and Winding is performed by the winding method.

Choose a reasonable coil size to reduce damage. When the winding thickness t, the winding length L, and the outer diameter D satisfy 3t + 2L = D, the loss is also the smallest. The coil with the shield is optimal when L/D = 0.8-1.2.

Select the diameter of a reasonable shield. Using a shield can increase the damage of the solenoid and reduce the Q value. Therefore, the size of the shield should not be too small. If the area of ​​the shield is too large, the volume will increase.
