The discharge cycle of the sediment at the bottom of the diesel transfer tank needs to be flexibly determined based on the frequency of use, oil quality, environmental conditions and other factors to ensure the cleanliness of the oil and the safety of the equipment. The specific suggestions are as follows:
1. Frequency of use orientation:
For diesel transport tanks that are used frequently, such as vehicles that undertake daily transfer tasks, it is recommended to discharge sediment once a week to promptly remove impurities accumulated due to frequent transportation; for low-frequency use, such as spare tanks that are only used 1-2 times a month, they can be discharged once a month to avoid excessive impurity deposition due to long-term static use.
2. Influence of oil quality:
If the diesel procurement channels are complex, the quality is uneven, or there is a mixture of different batches, the discharge cycle should be shortened to once every 3-5 days because the impurities and moisture content are difficult to control; if high-quality diesel that has undergone strict quality inspection is used, it can be appropriately extended to once every 10-15 days.
3. Environmental considerations:
For transport tanks in dusty and humid environments (such as construction sites and coastal areas), external pollutants and moisture can easily enter the tank body. It is recommended to discharge once every 5-7 days; in dry and clean environments, it can be relaxed to 7-10 days.
4. Special situation handling:
After the tank body has experienced long-distance bumps and bad weather, or before the planned oil change, it is necessary to discharge and check in time; if the diesel color is abnormally deepened, turbid, or the pipeline pressure changes suddenly during transportation, or the equipment fails, it should be discharged immediately and the tank body should be cleaned as appropriate.
5. Discharge operation points:
Before discharging, ensure that the tank body is left still for 4-6 hours to allow the sediment to settle fully; use explosion-proof containers to collect to avoid diesel leakage or static electricity.
After discharging, the sediment will be handed over to professional institutions for compliance treatment. It is recommended to establish an emission record ledger to record the time, emission volume, sediment status and other information in detail, so as to facilitate traceability analysis, timely discover potential problems and take countermeasures.
