1. Fault diagnosis and maintenance: The use of remote monitoring data to identify equipment faults, and timely maintenance and troubleshooting to reduce production losses.

2. Basic principles of equipment maintenance: Follow the principles of prevention first, comprehensive coverage, standard operation and detailed records, and regularly check and maintain all parts of the equipment, including electrical system, mechanical transmission system, hydraulic system, etc.

3. Lubrication and fastening: Special grease lubrication for gear and worm gear and other transmission components, add lubricating oil regularly to ensure smooth transmission and reduce wear. At the same time, regularly check the fasteners on the equipment to ensure that they are fastened reliably and prevent loosening leading to equipment failure.

4. Monitoring and adjustment: real-time monitoring of the temperature and oxygen concentration of the fermentation pile, control the humidity of the fermentation pile within a reasonable range, to prevent spontaneous combustion, explosion and bacterial growth.

5. Replacement of wearing parts and spare parts management: replace wearing parts and aging parts regularly, establish a sound spare parts management system, ensure the timely supply of key spare parts, reduce the downtime caused by lack of spare parts.

6. Safety training and management: Conduct training on the safety operation procedures and emergency measures for the operators of organic fertilizer equipment, establish a sound safety management system, strengthen the safety management of equipment, and prevent human damage and equipment accidents.

Through the above measures, we can ensure the stable operation of the automatic control system of the organic fertilizer production line, improve production efficiency and product quality, and reduce the failure rate and maintenance costs.
