In general, there are three smoke situations. (1) Black smoke. Why does a diesel generator emit black smoke is because the diesel is not completely burned, forming black carbon and being discharged? causes black smoke. There are the following five types: Wear of piston rings and cylinder liners After the piston rings and cylinder liners are worn, the compression pressure is insufficient, resulting in a change in the normal mixture ratio at the end compression. stroke of the cylinder, causing the fuel to burn under anaerobic conditions. The fuel injector is not working properly. The fuel injector does not atomize or drip oil, so the fuel cannot be completely mixed with the air in the cylinder and cannot be completely burned. The phenomenon of black smoke caused by a malfunction of the fuel injector is pMost obvious when the diesel engine is running at low speed. Since the air intake vortex into the cylinder is small during low speed operation, the possibility of oil droplets or oil jets being dispersed by the air flow is reduced and the droplets Oil remains longer, making it easier for black carbon discharges to form. The shape of the combustion chamber changes. The manufacturing quality of the combustion chamber shape does not meet technical requirements. If the compression gap is too large or too small and the piston is installed in the wrong position, the combustion will form. The chamber will be changed, thereby affecting the quality of the fuel and air mixture and worsening the fuel combustion conditions. Improper adjustment of the fuel feed advance angle (1) The fuel feed advance angle is too large and the fuel is injected prematurely into thehas combustion chamber. Since the pressure and temperature in the cylinder are low at this time, the fuel cannot ignite and burn. When the piston rises, the cylinder reaches a certain pressure and temperature, the combustible mixture burns. (2) The fuel supply advance angle is too small, and the fuel injected into the cylinder is too late. Part of the fuel does not have time to form a combustible mixture and is separated or discharged. The fuel discharged with the exhaust gases is decomposed. at high temperature, forming black smoke. 5. The fuel supply is too large, which increases the amount of oil entering the cylinder, resulting in more oil and less gas and incomplete combustion of the fuel. In addition, excessive workload, poor fuel quality and low operating temperature can also cause black smoke from the exhaust. (2) Fublue smoke Why does blue smoke appear? This is related to lubricating oil. The lubricating oil enters the cylinder and is heated and evaporates into blue oil vapor. Blue smoke is emitted with the exhaust gases. The main reasons are: the air filter is clogged, the air inlet is not regular or the oil level in the oil basin is too high (oil bath air filter). Lubricating oil is mixed with fuel. The piston rings are aligned and the cylinder gasket near the oil passage from the body to the cylinder head is blown. Wear of piston rings, pistons and cylinder liners (3) White smoke White smoke is caused by the white smoke emitted from the exhaust pipe of the diesel generator set when it is just started or when it is cold . It is formed by evaporation. of oil and gas due to the low temperature in the cylinder of the diesel engine. This is particularly true inwinter. If the exhaust pipe still emits white smoke when the engine is hot, this is considered a diesel engine failure. The main reasons are: the cylinder liner is cracked or the cylinder seal is damaged, cooling water enters the cylinder, and water mist or water vapor is formed when exhaust. The fuel injector has poor atomization and oil dripping. The fuel feed advance angle is too small. There is water and air in the fuel. The fuel injection pump pressure is too low or the piston, cylinder liner, etc. is damaged. are severely worn, resulting in insufficient compression force.
Why does the Ruizhi 06 generator emit smoke?
The generator emits black smoke and cannot be used.
The generator is smoking. The insulated enameled wire inside thegenerator is burned, causing a short circuit in the coil., the generator cannot be used.
Generators refer to mechanical equipment that converts other forms of energy into electrical energy. They are driven by water turbines, steam turbines, diesel engines or other electrical machines, and generate water flow, air flow, fuel combustion or nuclear fission. The energy is converted into mechanical energy and transmitted to the generator, which is then converted into electrical energy.
Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life. There are many forms of generators, but their operating principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is as follows: utilize suitable magnetic and conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction with each other to generate electromagnetic energy and achieve the goal of energy conversion.
History of invention
In 1832, the Frenchman Bixy invented the manual DC generator. The principle is to modify the magnetic flux in the coil by rotating the electromotive induced permanent magnet. force and produces this electromotive force in the form of direct voltage.
In 1866, German Siemens invented the self-excited DC generator.
In 1870, Gram of Belgium manufactured an annular armature and invented the annular armature generator. This type of generator uses hydraulic power to turn the generator rotor. After repeated improvements, it reached an output power of 3.2 kW in 1875.
In 1882, Gordon of the United States made a giant beep generatorhas a power of 447 kW, a height of 3 meters and a weight of 22 tonnes.
In 1896, Tesla's two-phase alternator began operating at the Nyala power station, and 3,750 kW, 5,000 V AC, was sent to Buffalo, 40 kilometers away. there.
Generator failure. The Ruizhi 06 generator smoked and the generator failed. If the generator emits black smoke, it means that some atomized particles from the diesel are being discharged without burning in the cylinder. There are mainly three reasons:
1. First, the fuel supply is too large and the diesel engine is overloaded.
2. Secondly, the injection pressure of the injector is low and the atomization degree of diesel is low.
3. Third, the oil supply is too late and the engine temperature is low. Troubleshooting method: For diesel engines with excessive fuel supply, reduceproperly supply fuel and monitor operation within normal load; For diesel engines with low fuel injection pressure, promptly repair or replace fuel injectors to increase fuel injection pressure. For diesel; engines whose fuel supply is too late, the fuel supply advance angle must be adjusted.
