Diesel generator set daily fuel tank as an indispensable auxiliary equipment of diesel generator set, because the technology is relatively simple, it is often ignored, not only in terms of safety, but also to a certain extent, it will affect the normal use of the unit. What is the cause of the diesel generator tank failure? What are the precautions to avoid failure? How to solve the failure? Beidou Power for your answer.
First, the causes of diesel generator tank failure
1. The fuel tank function design of diesel generator set is not perfect, such as no oil overflow port, water drain valve, etc.
2, diesel generator fuel tank has not been anti-corrosion anti-rust treatment, after a period of time, serious rust.
3, diesel generator fuel tank capacity indicator is not clear enough.
4, the supporting valve is not standardized, there are many water heaters instead, the effect is not ideal.
5, the design capacity is unreasonable.
Second, precautions to avoid the failure of diesel generators.
1, should pay attention to the standby diesel generator fuel tank made of stainless steel or steel plate, do not paint or galvanized inside the fuel tank, because they will chemically react with diesel, produce impurities that may cause damage to the diesel generator set and reduce the quality of diesel, cleanliness and combustion efficiency.
2, diesel generator tank storage location must be safe to prevent fire, the tank or oil drum should be placed in a visible place, appropriate away from the diesel generator, and strict regulations are not allowed to smoke.
3, after the diesel generator tank is placed, the oil level cannot be higher than the base of the diesel generator set by 2.5 meters, such as the oil level of the large oil depot is higher than 2.5 meters, the daily oil tank should be added between the large oil depot and the diesel generator set, so that the pressure of direct oil delivery is not more than 2.5 meters. Even during the shutdown of the diesel generator set, fuel is not allowed to flow into the diesel engine through the oil intake line or the injection line, relying on gravity.
4, the resistance at the oil port is not allowed to exceed the specified value of the use of clean filter elements specified on the performance data sheet of all diesel generator sets. This resistance value is based on the fuel tank is half filled with fuel.
5. The position of the oil supply pipe end of the oil tank should be about 50MM higher than the bottom of the oil tank of the diesel generator set to prevent sediment and water from being sucked into the oil supply pipe.
6. The oil supply and return areas of the fuel tank of the diesel generator set should be provided with perforated partitions to reduce the heat exchange of the diesel generator set.
7. The connection of the fuel return oil pipe should not cause shock waves in the oil pipe of the diesel generator set.
8. The fuel capacity in the fuel tank of the diesel generator set should ensure the daily supply.
Third, the method to solve the diesel generator fuel tank failure.
1. The internal and external surfaces of the fuel tank of the diesel generator set are treated with anti-corrosion treatment, which improves the level of anti-seepage and anti-leakage.
2, diesel generator fuel tank function design is perfect, reasonable design of oil spill port, breathing apparatus, oil inlet filter, normally closed tank cleaning port, etc.
3. Different from the glass tube and rubber tube oil gauge of other oil tanks, UPT series oil tank adopts indirect magnetic float column oil gauge. Because the display part is isolated from the oil, the display is clear and clear, and it will not be black for a long time.
4. All valve connections of diesel generator fuel tank are pressure-resistant and corrosion-resistant connectors.
5, diesel generator fuel tank and the unit is connected by thick wall copper pipe, wiring beautiful and reasonable, completely eliminate leakage phenomenon.
