Precautions for the use of the deionizing fan device
The static elimination device can be divided into AC and DC according to the high voltage type used by its discharge electrode (discharge needle). The AC is divided into high frequency and ordinary AC (commercial frequency), and the DC is divided into continuous DC. , DC pulse type.
The difference between the AC and DC static elimination devices is that a discharge needle of the AC type static remover can alternately generate positive and negative air ions. The discharge electrode is composed of a discharge needle and a ground electrode. A grounding electrode is required, and the discharge electrode is composed of separate discharge needles for positive and negative. When there is no external air supply (such as a fan, compressed gas, etc.), the DC static elimination distance is farther than the AC type. In the case where there is external air supply, the static elimination distance mainly depends on the static elimination distance. The structure, the air volume and the strength of the high-voltage power supply.
The difference between AC and DC static elimination devices is the difference in ion balance. The AC type static elimination device generates both positive and negative ions on the same discharge needle, so even if the discharge needle wears out for a long time, the ion balance There will be no major changes, and the ion balance performance is better. Since the discharge needle is composed of independent positive and negative electrodes, the ion balance is poor when used in close distance. In addition, the discharge needle is affected by the environment and the degree of contamination of the needle during use will affect the ion balance, especially the discharge After the needle is used for a long time, the degree of wear of the positive and negative discharge needles is different, and the ion balance cannot be corrected even after cleaning.
Since the discharge needle will be contaminated after long-term use, it will directly affect the static elimination performance and ion balance. Therefore, the static elimination electrode part should be cleaned regularly during use. Electrical appliances should be cleaned more frequently, and the degree of wear of the positive and negative discharge needles is different. Regular ion balance testing is required. When the discharge needle is severely worn, the discharge needle should be replaced in time.
