According to the “Planningâ€, the development of the Yellow River Delta has been given two missions: to undertake opportunities for development of the Tianjin Binhai New Area, to serve the Bohai Sea, and to face Northeast Asia; to rely on the Shandong Peninsula City Cluster and Jinan City Circle to support the sustainable development of Shandong Province. The director of the Shandong Provincial Development and Reform Commission, Fei Yunliang, said that the Yellow River Delta region is rich in natural resources, especially with more than 8 million acres of unused land. This has become a unique scarce resource in the context of the country’s strict control over construction land in recent years. At the same time, there is also Shengli Oilfield, China's second largest oil base, and a vast wetland.
According to the "planning", efficient eco-economy refers to the economical and intensive economic development model with typical ecosystem characteristics. In the type of industry, a circular economy industrial system composed of cleaner production enterprises is formed; in the industrial layout, an ecological industry group composed of a number of ecological industrial parks is formed; in the production process, no waste or less waste is used to realize the production process. Recycling and re-use are ultimately manifested in the efficient operation of the entire economic system and the coordinated development of economy, society and ecology.
“In its periphery, Tianjin Binhai New Area and Tangshan Caofeidian New Area have become a booster for China’s new round of economic development. After participating in the industrial division of Bohai Rim, it is expected to become an important growth pole for the coordinated economic development of eastern China. Fei Yunliang said.
Dongying City plays a leading role in the development of the highly efficient ecological economy in the Yellow River Delta. The mayor of the city, Zhang Jianhua, said that Dongying will invest 110 billion yuan in the development of the Yellow River Delta this year to develop petrochemical, petroleum equipment manufacturing and modern fisheries and animal husbandry. The three leading industries.
Binzhou has long advocated the development and construction of the Yellow River Delta. In September this year, the city proposed to take advantage of regional characteristics and advantages of marine resources, give priority to accelerating the construction of core areas and cutting-edge, and strive to foster the development of seven major industrial bases such as marine chemicals, ecological energy, equipment manufacturing, marine biological medicine, and port logistics.
It is reported that during the “Eleventh Five-Year Plan†period, Shandong will invest 1.5 trillion yuan to accelerate the development and construction of the highly efficient ecological economic zone in the Yellow River Delta. According to the "planning", the main economic indicators in the region will increase rapidly. In 2008, the regional production value was 475.6 billion yuan, and it is expected to reach 930 billion yuan in 2015 and 1.5 trillion yuan in 2020.
News Links The Yellow River Delta is located in Shandong Province and is currently China's last delta to be developed. In terms of location, the Yellow River Delta region is an important part of the Bohai Economic Circle, and it is also the middle zone where the industries of the Yangtze River Delta and the Pearl River Delta shift to the north. The Yellow River Delta Economic Zone includes all the cities of Dongying and Binzhou, as well as some adjacent counties and cities with similar natural and environmental conditions, with a total area of ​​26,500 square kilometers, accounting for 1/6 of the entire province.
In accordance with the principle of unity of high efficiency and ecology, harmony of development and protection, and harmony between man and nature, combined with the combination of natural resources, the “Planning†is planned and implemented according to the three types of functional areas: key development zones, restricted development zones, and banned development zones. Classification development plan. Among them, the key development zones are located on saline-alkaline lands 10 km away from the coastline and rely on the port and railway traffic lines to build the four major coastal industry zones in Dongying, Binzhou, Weifang and Laizhou and their provincial-level economic development. Regional and provincial industrial parks are featured industrial parks and high-efficiency eco-agriculture demonstration parks focusing on the production and processing of high-quality agricultural products. On this basis, a large chemical base, energy base, and logistics base will be constructed to develop the ecological industry and circular economy.
Conveyor Drum Pulley Bearing is rolling element bearing used in conveyor system. Usually use Spherical Roller Bearing and Self-aligning Ball Bearing in Conveyor Drum Pulley etc. which plays a role of reducing the friction among the components. Bearings support the rotating shaft and hence the pulley. The bearings are housed in 'plummer blocks' which enable the mass of the pulley assembly plus the belt tension forces to be transmitted to the pulley supporting structure.
Bearings used for conveyor pulleys are generally spherical Roller bearings, chosen for their radial and axial load supporting characteristics. The bearings are self-aligning relative to their raceways, which means that the bearings can be 'misaligned' relative to the shaft and plummer blocks, to a certain degree. In practical terms this implies that the bending of the shaft under loaded conditions as well as minor misalignment of the pulley support structure, can be accommodated by the bearing.
TYPES:
Due to customers` requirements, XKTE can offer different structures of spherical Roller Bearing , such as steel sheet metal frame structure(C type), brass solid cage structure(CA type/M type)
CC, CA Spherical roller bearings are special bearings, because the energy consumption of such bearings is relatively low, just toughness more advantages. CA, CC Spherical roller bearings can operate freely in high-speed machinery, as well as high rigidity Low-friction precision work in the popular, but also has high bearing capacity so much loved by the majority of users.
Both the dynamic load rating and rating life equations contain no difference regarding cage design and material (brass or steel)
CC Spherical roller bearings equipped with steel cages and operating in conditions of poor lubrication, may lead to adhesive wear and smearing. The hard steel contaminants that may appear, as well as the indentations that may form on raceways and rolling elements, act as locations for surface fatigue
brass cages have a much higher resistance to adhesive bonding and, for this reason, even in harsh conditions, when lubrication is insufficient, they enable bearings to attain the design rating life.
Some spherical roller bearing variants may include perforated outer ring and oil groove features in their design to facilitate easier lubrication and further extending their longevity. with the suffix W33 or H.
Self-Aligning Ball Bearing for conveyor drum pulley.
Main products are 1308-1316
APPLICATION:
Spherical roller bearing are available with heavy duty rollers and cages that are suitable for extreme demand harsh applications such as vibratory screens. Mining Conveyor Machine, and mining bulk Conveyor Pulley . In this sort of aggressive operational environment, the spherical roller bearing is the only type that delivers acceptable service life. generally have a longer life span than other bearing types.
Main Models:
Spherical roller bearing
Series 222.., 223.., 230.., 231.., 232.., 239.. 240.., 241.., CA/CC/W33
