Through the demagnetizing machine in what aspects are more suitable

Through the demagnetizer equipped with a conveying device, not only can reduce labor costs, but also work efficiency will be higher. However, due to the limitation of the installation space of the plate demagnetizer, there are certain requirements for the space size of the plate demagnetizer, so how much is the appropriate size of the conveying device? According to our field practice, it is found that the conveying length has a great relationship with reliability, taking into account the reliability to consider the design of the conveying device length, we recommend that the general demagnetizing machine engineers do 12 meters through the demagnetizing machine conveying device is more appropriate, comprehensive index comparison.

Our superior through the demagnetization machine sales department received through the demagnetization machine telephone consultation, often customers will ask, you can return the mold, caliper, stainless steel........... through the demagnetization machine Wait a minute? We encounter such customers you have to slowly clarify the role and scope of practice demagnetization machine, engineer's answer not through the demagnetization machine, not everything can be degaussed, the scope of application of the entire equipment is as follows:

1, the type of demagnetization machine is demagnetized by physical magnetic field, rather than thermal demagnetization, so the demagnetization site does not cause damage, non-destructive demagnetization.

2, the relative thermal demagnetization, demagnetization machine power is small, demagnetization effect is good, energy saving and environmental protection.

3, the premise of demagnetization through the demagnetization machine is that the demagnetization object must be a magnetic material or simply should be metal parts, copper, aluminum........ Except for waiting.

4. The effect of the type demagnetization machine is related to the demagnetization intensity of the type demagnetization machine, the size of the demagnetization workpiece and the material of the demagnetization workpiece.

5. Finally, even if the above three conditions are met, it cannot be said that demagnetization can be achieved. Demagnetization is related to the density of the material and the production process.

How to choose the magnetic powder material in the DC magnetic powder inspection equipment

It is very important to magnetize the object of the DC magnetic particle flaw detector. The general magnetic particle flaw detection machine generally adopts the method of magnetization, and the direction of the magnetic track and the direction of the magnetic field line are 90 degrees. In addition, for suitable magnetization, various methods can be used according to the shape of the flaw detection object.

First, the type of magnetic powder material

In order for the magnetic powder of the magnetic pole to stick to the wound to appear in the detection image, a small magnetic field of the magnetic powder should be used to magnetize the wound and adhere to the magnetic pole, which also needs to have perfect mark adsorption function. In addition, high resolution of magnetic particle image is required.

Magnetic particle detection equipment is used in the use of white, black, red and other different colors of magnetic particles under the light, as well as fluorescent magnetic particle testing machines using fluorescent lamps. From the different use of magnetic powder, dry powder and wet powder are used in water or oil.

Second, the use time of magnetic powder

The application time of magnetic powder can be divided into two kinds: one is the continuous method of magnetizing current using magnetic powder at the same time, and the other is the residual method of using the residual magnetic force of the detector when the magnetizing current is disconnected. In order to facilitate the detection of magnetic powder images attached to the wound, an environment that is easy to view needs to be created. General magnetic particles need to be observed in bright light, fluorescent magnetic particles need to be observed in dim light with ultraviolet lamps.

In order for the magnetic powder of the magnetic pole to stick to the wound to appear in the detection image, a small magnetic field of the magnetic powder should be used to magnetize the wound and adhere to the magnetic pole, which also needs to have perfect mark adsorption function. In addition, high resolution of magnetic particle image is required.

The magnetic powder used by the ultrasonic flaw detection machine factory in China uses white, black, red and other different colors of magnetic powder under the light, and uses fluorescent bright fluorescent magnetic powder. From the different use of magnetic powder, dry powder and wet powder are used in water or oil.
