Many Jiangxi three-ton sprinklers are not aware of the difference between Jiangxi's 3-ton sprinkler EGR engine and high-pressure common-rail engine. They often ask why high-pressure common rail is more expensive than EGR engine. Next, we will explain to you what is EGR, what is the high pressure common rail, and what is the difference between EGR and high pressure common rail engine? Let you see "EGR and high pressure common rail" as "clear, clear, and honest"! What is an EGR engine? EGR is an exhaust gas recirculation system that uses an electronic control system installed in the pump. Injectors are standard mechanical injectors whose injection control is a positional control. It can barely meet the country's three emission standards, but it does not have the basis to meet the country's four emission standards. EGR can be simply understood as follows: Exhaust gas recirculation means that part of the exhaust gas is reintroduced into the combustion chamber, which reduces the oxygen concentration in the combustion chamber, thereby lowering the combustion temperature and reducing the amount of nitrogen oxides generated. What is a high pressure common rail engine? High-pressure common rail abbreviation: EFI engine, is a more commonly used fuel injection system of modern diesel engines, it is provided by one or two independent high-pressure oil pumps to the diesel engine for fuel, mainly to provide high-pressure fuel rail, is the latest diesel engine A new type of oil supply. EGR gasoline engine fuel pressure is about 4P, diesel high pressure common rail can be much higher, the injection pressure of high pressure 1600 kg or more, and the track pressure is constant, the injector is solenoid valve type, ECU control solenoid valve opening, can achieve a cycle Multiple injections (5 times), precise control, is a type of time control. What is the difference between EGR and high pressure common rail engines? The high-pressure common-rail engine has a technically speaking momentum with respect to the EGR engine. The fuel consumption of the electronic fuel injection system is even lower and the noise is even lower. However, it has a high demand for fuel, and domestic oil technology has not yet reached its standard, so high-pressure nozzle clogging often occurs. High-pressure common rail price disadvantage: At present, China's three high-pressure common-rail engine emissions compared with the standard EGR engine in the price of 1-2 million more expensive, maintenance is also more trouble than EGR and more expensive. EGR life is poor: As the EGR engine uses exhaust gas to reduce the emission of nitrogen oxides, it will easily lead to poor combustion performance of the engine, and the service life will be worse than the high pressure common rail. Conclusion : Jiangxi's 3-ton sprinkler high-pressure common-rail engine is more economical and practical than EGR. It is an inevitable trend for the development of diesel engines in the future. Whether the engine uses high-pressure common rail technology or EGR technology, both will eventually reach the same goal, both to meet higher emission standards and reduce environmental pollution.
Product Profile Large energy saving ceiling fans are green energy saving products of the 21st century. It has many advantages, such as powerful, no noise, zero pollution, low energy consumption. It is very popular for large masses of users. It is not only mainly used in steel structure plant, logistics warehouse, farm and other large enterprise buildings, but also agricultural markets, gymnasiums, waiting rooms, exhibition halls and other large public buildings. A large energy-saving ceiling fans with a speed of 50 revolutions per minute 1 to 3 meters per second to make the human body feels the best wind speed. A breeze from all directions gently caresses the body and increases the evaporation of human sweat. The cooling effect of 5 to 8 degrees is similar to the comfort presented by the natural breeze, which can not be matched by other fans. It is an ideal choice for indoor, ventilation and cooling in summer to remove humidity and heat. Only seven degrees of electricity per day, it can be cool for a whole summer. Energy saving comparation In summer, the sun shines directly and the indoor temperature is more than 40 degrees on average. Common industrial exhaust fans can only increase the indoor temperature. Industrial air conditioners consume thousands of kilowatts of energy every shift. There is no obvious unenclosed cooling in the space, which also increases the operating cost of enterprises. The emergence of a large energy saving ceiling fan brought the perfect solution. An energy saving fan with a diameter of 7.2meters can push the air to produce a large amount of winds effectively. The continuously rotating blades of circular form an airflow field with an effective area of 600 to 800 square meters. No other device has not yet been compared. The large energy-saving ceiling fan praduced by Linter technology has the characteristics of high reliability, feasibility and low power consumption. The controller unit used the stability of the energy-saving inverter system. In practice, the average power consumption is less than one killowatt per hour. It can guarantee more than 5,000 hours of uninterrupted operation. Linter7200 of a large energy-saving ceiling fan can cover the area of about 50 small fans of 0.75 megabytes worked. In a factory of 9000 square meters, if full coverage is to be achieved, it needs about 300 small fans or industrial 6 energy-saving fans. According to the use of four years, every eight months, every day for ten hours, can be run for 10,000 hours, about 90000kw power consumption, than the small wind 1080000kw, save 990000kw, save energy by 92%. When meeting the extreme high temperature climate, the large energy saving fans and air conditioners are used together, it will be coller. Using A large energy-saving ceiling fan for air supply can not only save the air conditioning tube, but also save more than 30% energy. Attentio Lectotype The building structure: H-shaped steel, I-shaped steel, Mixed steel square bar spherical column spherical structure. The total height of the building is more than 4, 0m, less than 15m. 1, 0m. The minimum distance between the fan and the roof is 1, 0m. The minimum safety distance between the fan blades and the obstacle is 0, 3 m. The distance between the fan blades and the wall on both sides is more than 1, 5 m. Effects of various environments on fan performance. Open space, promotes air circulation. Indoor airflow circulation in enclosed spaces is suitable for use with air conditioning. In a multi-fan environment, due to the low wind speed, caused by the fan, there will be no cyclones. The distance between the two fans will be separated before the wind will not cancel, and the coverage area will be increased at the same time.
