Anti-static measures for machines in production
When it comes to static electricity, everyone is familiar with it. The principle is static electricity generated by the contact, separation or friction of different substances. For example, during the production process, there are a series of activities such as machine movement, handling and staff walking, sitting and standing. May generate static electricity.
Of course, 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 static electricity of the human body with anti-static equipment such as anti-static clothing and shoes. 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, the static electricity of the machine must be handled properly. The static electricity protection of the machine is generally through the elimination of electromagnetic fields, the shielding of high static electricity parts, and the machine Grounding is achieved. Generally, demagnetizers are used for degaussing, and ion fans are used to eliminate electric charges. The ion blower can generate abundant positive and negative ions, and blow these ions to objects with high static electricity, so the static electricity of the objects will be neutralized. These ions are generated by ionizing the air by the ion generating element inside the ion blower.
This ion generating element uses a low-current, high-voltage transformer to stimulate air ionization. The transformer also contains a current limiting resistor, which can enhance the stability and safety of ionization. The high-voltage alternating current acting on the circular circuit of the stainless steel ion emission point creates a strong alternating electric field at the top of the emission point. 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, for example, motors. Everyone knows that motors are prone to EMI, but they cannot be separated from motors. , So don’t prevent it from being shielded.
In addition, the best way to eliminate machine static electricity can also start from the overall production environment, for example, anti-static floors, floor mats, and all tools involved in production should use anti-static products as much as possible, so that static electricity will not remove itself.
