The top rapping shaft for electrostatic precipitators is used to drive the rapping and dust cleaning device at the corona electrode side of the electrostatic precipitator, serving as a transmission and insulation role. Insulators are suitable for use under working conditions where the working temperature does not exceed 160-500 ℃, the DC working voltage is 72KV to 100KV, and the altitude of the installation site does not exceed 1000m.
Insulators shall strictly comply with GB/T772-2005 Technical Conditions for High Voltage Insulator Porcelain Parts and B/T6746. Manufacture of Porcelain Insulators for Electrostatic Precipitators (3-1993). The surface of porcelain pieces shall be painted with white or brown glaze.
Note: Insulators of different material grades can be used in environments ≤ 160 ℃, ≤ 500 ℃, and the working voltage is 72-100KV.
When using various porcelain insulator products, it is necessary to install them smoothly and evenly under uniform stress. Before operating the equipment, heat and dry the porcelain bottle and installation location for about 12-24 hours (ensure that the porcelain bottle and installation location are clean and dry, free of moisture such as oil stains, and check whether the voltage meets the requirements) before operating the equipment. Sudden temperature rise and drop can cause the porcelain bottle to explode due to temperature differences.
