The device needs maintenance – what should be given special attention to?

Carefully prepare the maintenance plans/projects, carry out proper process preparations before shutting down the equipment, pay attention to safety during construction, have all the necessary tools and spare parts ready, and ensure that the equipment and processes are properly verified before starting up again...

1. Make a list of the problems that cannot be resolved on a regular basis, and work together with various departments and teams to figure out these issues. Try to resolve them all during maintenance activities, so as to avoid more difficulties in the future. 2. Replace the pump inlet and outlet valves as well as the bypass valves when necessary; otherwise, internal leakage will become severe and difficult to eliminate or repair. 3. Submit the required materials accurately, ensuring there is enough of them. Preparation of materials is crucial for maintenance work; if the gaskets and bolts you submit are incorrect or insufficient, it will cause problems later on. Make sure you understand the drawings clearly: know exactly what needs to be removed and what type of materials are required. 4. After opening the manhole on the container, clean out the debris inside and replace the drain valve; otherwise, combustible gases may leak internally in the future. 5. Train employees in advance regarding the knowledge needed for maintenance work, as well as the various quality control points – it’s necessary to provide thorough training on how to carry out these tasks and to what standard they should be done. Otherwise, you’ll end up being the only one running around, with no time to focus on more important matters. 5. I’m not sure whether your company is a state-owned enterprise or a private one; the procedures are particularly complicated in state-owned enterprises. If you work for such an enterprise, find someone in advance who is familiar with all the relevant departments so that they can handle the procedures on your behalf. Otherwise, dealing with various construction firms, manufacturers, and approval processes for temporary plans will drive you crazy. I'm talking from my own experience; I'm not sure if anyone has any good methods.

A few additional points: 1. Regular issues need to be analyzed thoroughly, solutions planned out, and relevant materials reported in a timely manner. 2. Prepare a maintenance plan in accordance with the process requirements. 3. Organize maintenance personnel to hold discussions and determine the best solution. 4. Establish proper emergency measures so that all participants are aware of what to do. 5. Ensure good coordination to avoid conflicts among team members; it’s advisable to have senior management involved as well
