China Diesel Generator Network reported: The overall orders of most diesel generator companies in the second half of this year have declined. Among them, orders for small and medium-sized diesel generator sets with large export volumes have severely shrunk, and some companies even made calls for 'the market winter is coming.' What impact will the financial crisis have on the diesel generator set industry? In the interview, most diesel generator set companies said that due to the market response, the real impact may not be revealed until the end of this year or next year. Diesel generator sets, the motor industry fluctuates. The reporter recently learned from Oriental Electric Group Oriental Electric Co., Ltd. and Harbin Power Station Group Harbin Electric Factory Co., Ltd. that the company has sufficient orders throughout the year, among which the demand for thermal power units has decreased compared with last year, but the orders for hydroelectric units are on the rise. During the bidding event for the Jinsha River Xiangjiaba and Xiluodu Hydropower Station hydropower stations not long ago, we signed

China Diesel Generator Network Report: Hydropower supply has always been an indispensable part of people's lives. Supply cannot be short of one moment. In order to prevent people from supplying water for daily life, the Yuqing Water Plant, the main water plant in Jinan, uses a diesel generator set composed of a combination of diesel engines and low-voltage generators as a replacement power supply to meet daily startup needs, and can maintain a daily water supply of 120,000 tons in case of emergency to prevent large-scale water outages. It is reported that this is the first case in the country, which has successfully solved the problem of the power supply of Yuqing Water Plant and improved the urban water supply guarantee capacity. In recent years, power supply problems have been plaguing Yuqing Water Plant.

China Diesel Generator Network Report: Since July 2008, Shandong Power Grid has implemented power restrictions, and the load of power grids in Weihai and Yantai has continued to rise. More than tens of thousands of small and medium-sized enterprises in various cities across the province have changed from 'five and two' to 'five and three' or even 'five and four' in May. In order to cope with the shortage of electricity, some small and medium-sized enterprises or commercial institutions have to purchase diesel generator sets themselves, small domestic Weifang diesel generator sets, Shanghai Dongfeng diesel generator sets, and Cummins diesel generators form popular products. On the morning of the 6th, Weihai Power Supply Company dispatched data from the high-level, economic zones and Huancui zones. Since mid-July, the company has received 8 new self-produced generator sets from the enterprise, including 6 new high-power diesel generator sets of 100 to 800 kilowatts in the economic zone alone. The dispatcher said that these companies belong to the electronics, food, textile or construction industries. Because they have foreign trade orders, they attach great importance to delivery on schedule, so they are self-employed.

In order to extend the service life of diesel generator sets, Haixing reminds users to pay special attention to the maintenance work of diesel generator sets in winter. Only by paying attention to the impact of cold climate on the generator set during daily use in winter can the diesel generator set be protected from damage. 1: Avoid choosing fuel at will. The low temperature in winter makes the fluidity of diesel worse, the viscosity increases, and it is not easy to dissipate, resulting in poor atomization, deterioration of combustion, and deterioration of the power and economic performance of the diesel engine. Therefore, light diesel should be used in winter with low cooldown points and good ignition performance. It is generally required that the defrost point of the diesel engine should be 7-10℃ lower than the local minimum temperature in the current season. 2: Use open flame to help ignite. The air filter cannot be removed, and then ignite it with cotton yarn dipped in diesel, and then made into a ignition object and placed in the intake pipe to assist in the combustion start. In this way, during the startup process, the dust-containing air from the outside will be directly sucked into the cylinder without filtering, causing abnormal wear of pistons, cylinders and other parts, and also causing

Among the fuel injection systems that have the most significant improvement in combustion effects, 'high-pressure injection' and 'injection freedom' have become important means in current fuel injection systems.The common rail injection system has entered the second generation, and can achieve an injection pressure of 160-180MPa and five multi-stage injections within the variable range of the injection period above 180°C.In the future, through measures such as improving the strength of each part of the common rail injection system and reducing oil leakage, it is expected to achieve high-pressure injection above 200MPa.In the future, there are methods to improve combustion such as premixed combustion and low NOx combustion. In order to achieve premixed combustion, measures such as multi-stage injection and switching combustion methods that can promote premixing are adopted, which requires a higher degree of injection freedom.In addition, due to high EGR and low NOx combustion, it is necessary to consider further increasing the injection pressure as a black smoke countermeasure when the O2 concentration in the intake air is greatly reduced.On the other hand, the combination of fuel injection system and after-treatment technology is also very important.

one. What are the conditions for generator sets to operate side by side? The entire process of putting generator sets into parallel operation is called parallelism. Run one generator set first and send the voltage to the busbar. After the other generator set is started, it is parallel to the previous generator set. At the moment of closing, the generator set should not experience harmful impact current and the shaft should not be hit suddenly. After closing, the rotor should be pulled into synchronization quickly.

The current diesel generator industry is such that investing in diesel generator fields will result in no return or even loss of money. However, some people still invest, and there is a huge demand for diesel generator equipment.Where opportunities exist in the market, competition exists where opportunities exist. Where competition exists, there is no way to escape the natural law of 'big waves wash away the sand, and the survival of the fittest'.Currently, 1/3 of the wind turbines are basking in the sun because the grid connection problem has not been solved.The entry barrier for the fan manufacturing industry is low, and 80% of the more than 70 complete machine manufacturing companies are simple assembly plants.Blades, generators, gearboxes, etc. are purchased from upstream parts companies, assembled and sold in various specifications, causing difficulties in grid connection.A few months ago, a new fan installed by a fan manufacturing company fell from the air and was damaged.It’s time for the market, which is a mixed bag of good and bad, to be cleaned up.Policies are becoming more and more standardized, the need for the introduction of standards is becoming more and more urgent, and competition is becoming more and more fierce. After the golden years of explosive growth, diesel in the post-'golden era'

The power shortage and frequent pull-out limiting electrodes have greatly affected people's lives and industrial production, and have also caused diesel tension in Zhejiang, Jiangsu and other regions to be tight and even partially out of stock, because the company's own diesel generator sets consume a large amount of diesel. This year's power shortage has arrived unexpectedly. According to data, except for Heilongjiang, Jilin, Liaoning and Xinjiang, other regions across the country have experienced power cut-offs to varying degrees. Similarly, Zhejiang, Jiangsu, Shanghai, Guangdong and other places are still the best. In view of the lessons learned last year, more companies, especially foreign trade processing companies, have to purchase diesel generator sets to deal with the panic in order to complete foreign orders on time and deliver goods in a timely manner. Some diesel generator manufacturers have launched 'out of stock' signs, and the large demand has brought some diesel engine manufacturers that were originally 'in desperate situations' back to life. The price of diesel generator sets is also high, with the price of 200KW diesel generators rising from 120,000 to 130,000 yuan to 200,000 yuan.

The Development of China's Ultra-Large Displacement Diesel Engines my country's automotive diesel engine market has gone through several important time points from the quasi-heavy-duty stage to the super-heavy-duty stage of more than 10L.Among them: 2003 was the period of intensive launch of quasi-heavy-duty diesel engines, and the displacement was concentrated at 7L; 2005 was the first stage of heavy-duty diesel engines, and the displacement was concentrated at more than 8L; 2006 was the second stage of heavy-duty diesel engines, and the displacement was between 9 and 10L ; From the second half of 2008 to the present, major manufacturers have begun to focus on the launch or mass production of diesel engines above 10L, and vehicle diesel engines have entered a period of super heavy-duty and large displacement above 10L.The characteristic of this period is that it is based on 11L and aims at the next displacement range-12~13L.The current situation of supporting extra-large displacement diesel engines and complete vehicles. Since 2008, some new 12L and 13L extra-large displacement diesel engines have been launched by various diesel engine factories one after another, thus making my country's extra-large displacement heavy-duty engines above 10L
