The valve body is an important part of the equipment and pipeline, and its maintenance must be combined with the equipment and pipeline maintenance plan. The valve manufacturer of Shanghai Ruwei Automation Technology Co., Ltd. recommends: Refinery equipment is overhauled every year, and thermal power plant generator sets are overhauled in two years. Equipment and maintenance valves caused by overhaul should be overhauled or replaced at the same time.
The equipment maintenance and overhaul procedures formulated by the original fuel chemical department of the refinery. Imported solenoid valves are used for oil products with a rated pressure of 16MPa and a medium temperature of 550℃ or less for the refinery, as well as high, medium and low pressure valves for steam, water and various gases. The maintenance content of the vehicle is regulated, divided into minor repair type, medium repair type and overhaul type.
For the management of valve maintenance sites, various management systems with economic responsibility as the core should be established and improved. The valve material management should be collected and kept by a part-time custodian, and the accounts should be consistent. Spare parts, parts, materials, and appliances should be placed separately to make them easy to clean and use. Prepare accessories and materials according to production needs.
It should be managed by a dedicated person, maintained by a dedicated person, and maintained regularly, and a practical safety technical operation procedure should be formulated according to the equipment performance.
The management of maintenance and production must have annual, quarterly, and monthly plans, and the original record of the solenoid valve brand must be complete and complete. Individual production plans should be contracted or broken down. Quantity and cost should be considered when issuing plans to prevent repairing only medium-sized and small-sized valves but not large-sized valves, or only large-sized valves but not small-sized valves, and only expensive valves. Do not repair ordinary valves. The squad leader must correctly implement the maintenance plan, be good at coordinating the relationship between the various links, and ensure the smooth progress of the maintenance work.
