Why design a diesel loading platform? A diesel loading platform is a specialized loading and unloading facility in the petrochemical industry, with the core function of achieving safe, efficient, and sealed transfer of diesel from storage tanks to transport tankers.
1. Core Design Reason 1 Safety protection: Diesel fuel belongs to flammable dangerous goods (Class III), and the loading platform directly eliminates the risk of combustion and explosion through explosion-proof electrical, static elimination, emergency cut-off, combustible gas monitoring and other systems. 2. Environmental compliance: The country requires the recovery and treatment of volatile organic compounds (VOCs) (GB 20950-2020), and the loading platform is equipped with an oil and gas recovery device (recovery rate ≥ 95%) to prevent gas emissions during the loading and unloading process. 3. Accurately measure the integrated quality flow meter (accuracy level 0.2) and automatic batch control system, achieve trade settlement level data management, with an error rate of less than 0.35%, and avoid measurement disputes. 4. Process efficiency improvement: Quantitative loading instrument (QLL) and anti overflow interlock system are used for single vehicle oil loading. The time is reduced to 15-25 minutes, and the throughput efficiency is increased by more than 40% compared to manual operation.
2. Key technical parameters (based on the latest design standards of Sinopec) • Design pressure: -500Pa~+1500Pa (oil and gas pipelines) • Loading speed: Initial silver reserve ≤ 1m/s, normal ≤ 4.5m/s • Static grounding resistance:<10 Ω (ASTM standard) • Emergency shut-off valve response time:<3 seconds • VOCs emission concentration:<10g/m ³ (national st
3. Warning for dangerous operation. It is strictly prohibited to operate the imitation breakfast tank truck without effective static grounding. Diesel vapor can be ignited when the energy released by human static electricity reaches 0.1mJ (minimum ignition energy is 0.25mJ).
.2. How to clean a broken air flow meter in a diesel car
Cleaning process for an undamaged air flow meter in a diesel car:
1. Safety preparation and disassembly. Disconnect the negative pole of the battery: Before cleaning, disconnect the negative pole of the vehicle battery to avoid circuit failure or electric shock risk caused by short circuit during operation.
. Locate and remove the air flow meter: The air flow meter is usually installed on the intake duct, near the air filter and throttle valve. When disassembling, pay attention to the position of the fixing screws or buckles to avoid damaging the sensor housing or connecting wires.Secondly, for cleaning the sensor part, choose a cleaning agent: preferably medical alcohol: use medical alcohol with a concentration of 95% or 99%, and gently wipe the sensor surface with a cotton swab.
. Alcohol is highly volatile and non corrosive, and can effectively dissolve oil stains and dust. Stubborn stain treatment: If there is stubborn carbon or oil sludge on the surface of the sensor, a dedicated electronic cleaner (such as circuit board cleaner) can be used, but it is necessary to ensure that the cleaner does not contain corrosive components. It is strictly prohibited to use carburetor cleaning agents, gasoline, or ammonia containing cleaning agents, as these substances can damage the precision components inside the sensor. Cleaning method: Dip a cotton
