(Summary description)Note 1: The oil storage room of the diesel generator room is not equipped with a breather pipe and a breather valve with a flame arrester. According to Clause 2 of Article 5.4.15 of Code for Fire Protection Design of Buildings GB500162014 (2018 Edition): "The oil tank in the oil storage room shall be sealed and equipped with a breather pipe leading to the outside. The breather pipe shall be equipped with a breather valve with a flame arrester (which must be indicated in the design description of electrical or HVAC drawings)." The correct approach is to set the site according to the requirements of the specification. The site selection should be concealed and not easily damaged. Note 2: Improper selection of detectors in diesel generator room and oil storage room. According to Article 5.4.13.6 of the Code for Fire Protection Design of Buildings GB500162014 (2018 Edition), "When automatic sprinkler systems are installed in other parts of the building, the diesel generator room shall be equipped with automatic sprinkler systems", the automatic sprinkler system fire extinguishing system is generally used in the generator room, and the thermal detector is selected for the generator room detector. The fire extinguishing form of the oil storage room is generally the dry powder automatic fire extinguishing system, because the control mode of the system is generally divided into two types (temperature control and electric control). If the electric control is required to be controlled by the fire alarm linkage, then the oil storage room detector should select the combination of temperature and smoke detectors, otherwise, the temperature detector can be selected. The correct way is to select the detectors in the generator room and oil storage room according to the fire extinguishing form of the room. Pay attention to confirm the fire extinguishing form of the above places with the water supply and drainage discipline. Note 3: The diesel generator room uses ordinary lamps; The common rocker switch for lighting in the oil storage room of diesel generator room is set in the oil storage room. According to the Code for Design of Electrical Installations in Explosive Atmospheres (GB500582014), the diesel oil with flash point greater than 60 ℃ is currently used in the self-provided diesel generator set, so the daily fuel tank room is classified as a non-explosive hazardous area. If the daily oil tank room is really designed according to the explosion hazard area, all disciplines such as architecture, structure, ventilation and electrical must consider explosion-proof, otherwise all previous efforts will be wasted; However, the current specifications or atlas examples obviously do not do this. The correct approach is to use sealed (waterproof and dustproof) ordinary lamps in the oil storage room of the diesel generator room. The lamp switch in the oil storage room can be installed outside the oil storage room and can be installed inside the oil storage room. The distribution box should not be installed in the oil storage room, and the junction box should also be sealed (waterproof and dustproof).

Internal structure of Diesel generator

The internal structure of Diesel generator usually includes the following main components: Diesel engine (internal combustion engine): It is the core part of the generator set, used to convert the energy generated by fuel combustion into mechanical energy. It includes components such as cylinders, pistons, crankshafts, connecting rods, etc. Crankcase: used to install the crankshaft and connecting rods, providing support and lubrication for the engine. Piston ring: A circular component located on the piston, used to seal the gap between the piston and the cylinder, preventing high-pressure gas leakage in the combustion chamber. Cylinder and cylinder head: The cylinder is the place where the internal combustion process occurs in the engine, and the cylinder head is used to seal the upper part of the cylinder. Valve and valve drive mechanism: responsible for controlling the intake and exhaust processes, ensuring the inflow of fuel mixture and the discharge of exhaust gases. Fuel system: includes components such as fuel tank, fuel filter, fuel pump, and fuel injector, used to supply fuel to the combustion chamber for combustion. Air intake system: including air filters and intake ducts, used to introduce air into the combustion chamber. Exhaust system: including exhaust pipes and mufflers, used to exhaust the exhaust gas generated after combustion. Cooling system: including cooling water tank, water pump, radiator, etc., used to reduce engine temperature and maintain its normal operating temperature. Lubrication system: including oil tank, oil pump, and oil filter, used to provide lubrication for the engine and reduce friction and wear of components. Starting system: used to start the engine, usually including a starting motor and starting circuit. Generator: The generator generates electrical energy by turning the engine. Control panel and control system: used to monitor and control the operating status of the generator set, including parameters such as voltage, current, frequency, temperature, etc. These are the main components of Diesel generator, and different types and specifications of Diesel generator may have some differences. Understanding the internal structure of a generator helps to better understand its working principle and maintenance methods.

Several Precautions for Summer Maintenance of Diesel Engines

Summer is a hot season for diesel engine operation. In order to ensure the performance and lifespan of the diesel engine, the following are some precautions for summer maintenance: Cooling system inspection: Ensure that the coolant level in the cooling system is sufficient and the coolant concentration is appropriate. At the same time, check whether the water pump, radiator and cooling fan of the cooling system operate normally, and clean the surface of the radiator to prevent the blockage of dust and dirt. Air filter maintenance: Clean or replace the air filter to ensure that the engine receives sufficient and clean air. In summer, there is a lot of dust in the air, which can easily block the air filter, leading to insufficient air supply and affecting combustion efficiency. Fuel quality: Use high-quality fuel and avoid using inferior or unknown sources of fuel. Poor quality fuel is prone to impurities, leading to fuel injector blockage and incomplete combustion, which affects engine performance. Lubrication system inspection: Ensure that the oil level is appropriate and the oil quality is good. Under high temperatures, the lubrication needs of the engine are higher, so it is necessary to regularly check the concentration and cleanliness of the engine oil, and replace the engine oil and filter in a timely manner. Battery maintenance: High temperatures in summer can easily cause battery moisture to evaporate. Check the battery electrolyte level and add distilled water if necessary. Keep battery terminals clean to prevent corrosion. Transmission system inspection: Regularly check the working status of the clutch, transmission belt, and gearbox to ensure smooth operation of the transmission system. Ventilation of engine room: ensure good ventilation of the engine room, install Sun visor or shelter to avoid direct sunlight and reduce the internal temperature of the engine room. Regular maintenance: Summer is a hot season, and maintenance of diesel engines is more important. Regularly conduct comprehensive inspections and maintenance to ensure timely repair of problems and prevent the occurrence of faults. In summary, summer maintenance is crucial for the performance and lifespan of diesel engines. Following the above precautions and conducting regular inspections and maintenance can ensure stable operation of diesel engines under high temperature conditions and improve their service life. If you are not familiar with the maintenance of diesel engines, it is best to hire professional technical personnel for inspection and maintenance.
