This standard is a revision of JB5906-91 "General technical conditions for C-type anode plates for electrostatic precipitators". When this standard was revised, it stipulated the requirements for various deformation states of the pole plates, such as bending, twisting, and waviness. When measuring, place the plate sideways on a special inspection device and use the two-point method to measure. This makes the measurement of these shape deviation items closer to the use state and facilitates product quality control.
This standard will replace JB5906-91 from the effective date. This standard is proposed and centralized by the Electrostatic Precipitator Sub-Technical Committee of the Environmental Protection Machinery Standardization Technical Committee of the Ministry of Machinery and Industry. The main drafting unit of this standard is: Shanghai Metallurgical Mining Machinery factory. The organization participating in the drafting of this standard: Kunshan Chengbei Corona Wire Factory. The main drafters of this standard: Yuan Hongrui, Zhu Huafu, Wang Fengen, Xu Yulong. This standard is interpreted by the Electrostatic Precipitator Sub-Technical Committee of the Environmental Protection Machinery Standardization Technical Committee of the Ministry of Machinery. 1 Scope
