Precautions When Changing Lubricants in NPK Fertilizer Production Lines
When changing lubricants in npk fertilizer produciton line, the following precautions apply:
1. Preparation: Before changing the lubricant, thoroughly clean the lubricating parts of the fertilizer equipment. This includes removing old oil, dust, and impurities to prevent contamination of the new oil. Inspect the equipment's lubrication system, including the oil pump, oil pipes, and oil tank, to ensure there are no leaks or damage. Select only qualified lubricants. Ensure that the lubricant's type and performance indicators match the equipment's operating conditions.
2. Change Procedure: When changing the lubricant, completely drain the old oil. Ensure that all old oil in the oil tank, oil pipes, and lubricating parts is completely removed. When adding new lubricant, use clean refueling tools. Determine the amount of lubrication to be added each time based on the equipment's lubrication requirements. Ensure adequate lubrication while avoiding excess lubrication that could cause waste or leaks.
3. Follow-up Inspection: After refueling, check that the oil level has reached the specified level. After the equipment has been running for a period of time, check that the lubricating oil temperature and pressure are normal. If any abnormalities are found, shut down the equipment for inspection. Regularly inspect the lubricant's physical and chemical properties. Visually inspect the lubricant's transparency and color changes to determine if it's aged or contaminated.
4. Safety and Environmental Protection: When changing lubricants, ensure the equipment is shut down. Avoid changing lubricants while the equipment is running to prevent accidents.
By following these steps, you can ensure proper lubrication during lubricant changes in your nitrogen, phosphorus, and potassium fertilizer production line, extending equipment life and improving production efficiency.
