Anti-static measures for machines in production
When it comes to static electricity, everyone is familiar with it. The principle is the static electricity generated by the contact, separation or mutual friction of different substances. Static electricity may be generated.
Of course, the static electricity in the production process is nothing more than two aspects, one is the static electricity of the human body, but the static electricity generated by the rotation of the machine. We can start with the personal anti-static equipment, such as anti-static clothing, shoes, etc. Deal with the static electricity of the human body, but we will focus on introducing the static electricity generated by the machine in production.
The machine is a high-static power source. Because the mechanical parts of the machine, especially the engine, are prone to electromagnetic induction, it is necessary to deal with the static electricity of the machine. Grounding, etc. to achieve, the general degaussing is borrowed from the degaussing device, and the ion fan is used to eliminate the charge. The ion blower can generate abundant positive and negative ions, and blow these ions to high static objects, so the static electricity of the objects will be neutralized. These ions are generated by the ion generating element inside the ion blower, which ionizes the air.

This ion generating element is excited by a low current, high voltage transformer to ionize the air. The transformer also contains a current limiting resistor, which enhances the stability and safety of the ionization. The high-voltage alternating current acting on the circular circuit of the stainless steel ion emission point forms a strong alternating electric field at the top of the emission point, and this electric field ionizes the air and produces pole-changing ions. When the electromagnetic field cannot be eliminated or is difficult to eliminate, we use electrostatic shielding equipment to shield high-static equipment or high-static parts of the equipment, such as motors, as we all know, motors are prone to EMI, but the machine cannot run without the motor , so, be sure to block it.
In addition, the best way to eliminate machine static electricity can also start from the overall production environment, such as anti-static floors, floor mats, and use anti-static products as much as possible for all tools involved in production, so that static electricity is not removed and self-retreating.
