According to the Shandong Machinery Industry Association, from the January to November 2013 economic operation of the machinery industry in the province, the "winter" of the Shandong Machinery Industry has passed, and the cumulative growth of the main indicators such as main business income and total profit has been restored. To about 15% of the normal level.
It is understood that in 2013, the overall income and profits of the Shandong Machinery Industry fell sharply in the first quarter, and the province’s machinery industry accounted for more than half of the 14 sub-sector losses. The situation is very grim. After a series of efforts such as technological transformation and scientific and technological innovation, the overall economic efficiency of our province's machinery industry has picked up moderately. From January to November 2013, 11666 enterprises above designated size in the machinery industry of our province had achieved a total income of 2,514.144 billion yuan, a year-on-year increase of 14.95%, and a total profit of 163.951 billion yuan, an increase of 15.39% compared with the previous year. The main indicators such as main business income, total profits and taxes, and total profits of the machinery industry in Jiangsu province ranks second among all provinces and municipalities in the country after Jiangsu.
Shandong Machinery Industry Top 100 released Shandong Machinery Industry Association recently announced the province's top 100 machinery industry enterprises, Weichai, heavy truck, when the wind and other companies on the list.
It is understood that last year, the province's large-scale mechanical industrial enterprises in the main business income, the total amount of profits completed were 2.7706 trillion yuan, respectively, 186.8 billion yuan, an increase of 15.06%, respectively, 16.41%. The major economic indicators, such as operating income and total profits, ranked second in the national machinery industry and ranked second among the 14 industrial sectors in the province. Among them, the top 100 companies achieved a total revenue of 575.6 billion yuan from their main business and a total profit of 29.1 billion yuan, accounting for 21% and 16% of the total machinery enterprises above designated size.
This year, the growth rate of the machinery industry will continue to slow. Cai Weici, vice president of the China Federation of Machinery Industry, said on the same day that this year, the overall external environment for the development of the machinery industry is unlikely to change significantly. It is expected that this year's mechanical industry will increase production and sales and profits this year. The speed will reach about 12%, and the export growth rate is expected to reach about 8%.
"The total demand for mechanical products in this year is expected to continue to grow at a moderate rate without drastic changes, but due to the ever-increasing number of bases, the increase will continue to slow. It is expected that the division of machinery and industrial enterprises will further increase in the future. The merger and reorganization between enterprises will continue to accelerate.†Cai Weici said that machinery companies must enhance their awareness of the crisis and accelerate their own quality and competitiveness. Focusing on attacking the high-end and bases as the main focus points for structural adjustment, the transition to a development approach that focuses on innovation, integration, and green development will be adopted.
Motocycle battery mainly used for various specifiction of motocycle staring and light, usually motocycle battery is also called motocycle starting battery.
Electric motorcycle battery is the small heart of electric motorcycle. Its safety, environmental protection and durability are the most important performance for consumers. Currently motorcycle battery already renovate the traditional process of lead-acid batteries and establish a new green environmental protection and energy-saving process. Because the traditional chemical conversion process is cut off and the main pollution is eliminated, the product is environmentally friendly; the quality is high, the service life is long, the capacity is large; the low temperature start performance is good, and it is especially suitable for use in cold regions in the north. As a power battery, it can be discharged at a high rate; it has a small self-discharge and is suitable for long-term storage; it has obvious cost performance advantages compared with other imported batteries.
Motorcycle battery use and maintenance According to the technical conditions of the battery, the correct charging voltage of the motorcycle battery should be maintained at 13V-16V, and the charging current should be 0.1A-2.5A. Some motorcycle manufacturers have set the clamp voltage of 15V, which is more suitable and can be used for reference. But there are many motorcycle manufacturers lack of knowledge in this respect, the charging system is not strictly controlled, resulting in no regulation of the charging voltage, current, with the increase of engine speed and increase, high speed can reach 18V4A above, so that the rapid evaporation of battery electrolyte affect its performance, especially for maintenance-free battery, because of the rapid evaporation of electrolyte and shorten its life; Some motorcycles charging voltage is very low, only 13V or lower, so that the battery long-term charging insufficient failure, consumers do not know the reason, only constantly replace the battery. For these cases, consumers should check the charging system in time, replace the rectifier regulator, motorcycle electrical parts manufacturers should fully grasp this knowledge, produce products that meet the technical requirements. The main electrical components which have direct influence on the use of battery are: rectifier regulator, electric door lock, starting relay, anti-theft device and so on. In order to pursue low cost and low price, some enterprises produce electrical components that do not meet the requirements at all. For example, the electric door lock cannot completely cut off the circuit when it is closed, the rated current of the immobile device is greater than 5mA when it is in standby state, and the rectifier regulator only has the function of rectifier without regulating voltage and current. Consumers should carefully judge and buy electrical components of good quality that meet the requirements. One, usually how to maintain the battery.
1. How to maintain the battery in use the battery should be regularly checked the liquid level of the electrolyte, so that it is located in the specified range. If the electrolyte splash, pour and cause the liquid level to drop, it should be added a certain proportion of electrolyte. If it is because the distilled water is evaporated and the liquid level drops, then the distilled water should be added. For the normal use of batteries to add the main should be distilled water, because sulfuric acid is almost not consumed. The filling plug should be covered in time after charging and filling; The surface of the battery should be kept clean to prevent debris from entering the battery and causing short circuit and self-discharge between the electrodes. The battery shell should be maintained to avoid breakage. Electrolyte leakage is found, should be cleaned in time to prevent the surrounding parts by acid corrosion. Positive and negative terminals have good electrical conductivity. If the surface is oxidized or corroded, it should be cleaned in time and coated with butter.
Three, how to safely use battery plus electrolyte to use protective equipment, beware of electrolyte overflow or splash on the skin. The remaining electrolyte should be kept in a container and neutralized with quicklime when discarded. Before charging, the filling plug should be opened, because the battery should release a lot of gas when charging. In addition, pay attention to good ventilation in the charging room, and smoking should be strictly prohibited.
Dispose the waste battery in time to prevent the electrolyte from flowing out and damaging the surrounding objects. Not to be played with by children. When the electrolyte touches the skin, wash with clean water immediately; If splashing into eyes, rinse immediately with water for 15 minutes. The electrolyte is mistakenly eaten into the body, immediately drink water for several mouthfuls, and then the egg white and emulsion mixed drink; You can drink a lot of water and rest. When the electrolyte is splashed on the clothes, wash them with water immediately and then neutralize them in a weakly salty solution.
