Operation instruction and maintenance manual of nitrogen storage cabinet

1. Overview With the development of microelectronics industry, many special microelectronic devices and circuits have appeared. In order to avoid the influence of trace corrosive harmful gases such as oxygen, water vapor and dust in the atmosphere, these products need to be stored in high-purity nitrogen environment, so the demand for nitrogen purification storage cabinets is increasing. On the basis of analyzing the nitrogen filling system of gas seal welding equipment imported from abroad, according to the specific use requirements, the equipment was designed and improved many times, and the first nitrogen filling storage system in China was developed. The microcomputer chip was used to control the nitrogen source in the whole process and automatically reach the set humidity. The equipment has the characteristics of simple operation, humanized management, cost saving and automatic constant humidity and pressure. 2. Main technical indicators Product model: QUX-3 150 Inner cavity size:1350 mm×1870 mm× 600 mm (width× height× depth). Static nitrogen consumption:
