Foreword

This procedure has been prepared in accordance with the requirements of the State Food Administration's Letter Management [2003] No. 173. And according to the National Grain Bureau National Reserve Grain Depot The requirements of the construction office meeting minutes 149 (November 19,.2003), the name of the procedure was installed by the "food shallow round warehouse mechanical and electrical equipment The Technical Regulations for Commissioning was changed to the Technical Regulations for the Installation of Mechanical and Electrical Equipment for Grain Warehouses. The content of the regulations was also expanded from shallow round warehouses to flat warehouses and The main warehouse type of silos and other current grain warehouses in China. In recent years, China's grain storage and transportation facilities have developed rapidly. The newly built grain depots are mechanized and highly automated, and the installation and commissioning of electromechanical equipment are all Higher requirements were raised. The industry has not had technical standards for the installation and commissioning of the grain and storage electromechanical systems, the installation and commissioning of electromechanical systems. There is no rule to follow the acceptance work, and there is no need for regulation. In order to guide the installation and commissioning of mechanical and electrical equipment in grain warehouses, to ensure the quality of the project and improve economic efficiency This regulation is specially formulated to promote technological advancement in the industry and ensure production safety. This regulation is a mandatory standard for the food industry. This regulation stipulates the general technical requirements for the installation and commissioning of mechanical and electrical equipment for grain warehouses. As this standard is the first domestic regulations on the installation technology of mechanical and electrical equipment for grain warehouses, in order to improve the quality of procedures, all units are required to implement During the process of this procedure, pay attention to summing up experience, accumulating information, and feedback relevant opinions and suggestions to Zhengzhou Branch of National Grain Reserve Bureau at any time. Research and Design Institute (Address. No. 153, Nanyang Road, Zhengzhou City, Henan Province, post code 450053) for future reference. This regulation was proposed by the Department of Circulation and Technology Development of the State Grain Administration. This regulation is under the jurisdiction of the National Grain and Oil Standardization Technical Committee. The chief editor, the editorial unit and the main drafters of this procedure.
