China Drying News In 2012, faced with the grim situation of global economic downturn and continued downward pressure on the domestic rare earth market, Baotou City, Inner Mongolia took a variety of measures and actively tackled the unfavorable factors, achieving 179 batches of exported rare earth products. 4086 tons, the value reached 93.91 million US dollars.
Since 2008, due to the continuous impact of the international financial crisis, the international market demand for rare earth has continued to decline. With the introduction of the national regulatory quotas and the introduction of macro-control policies such as the minimum price set by the customs, the export volume of rare earths in the Baotou region has been declining year after year.
It is understood that in 2012, the country listed 70 kinds of rare earth primary products in the “Legal Inspection Catalogueâ€. In order to better maintain the export order and ensure the quality of exported rare earth products, relevant departments of Baotou City have taken a series of effective measures to do a good job in export supervision and supervision of rare earths: First, to further improve the export supervision and inspection model of rare earth, and strengthen production, processing and storage. The source control and process control of the transportation and other links shall prevent the incorporation of foreign impurities; secondly, do a good job in the classification management of export rare earth production enterprises; regularly check and supervise the export of rare earth production enterprises to ensure the effective implementation of inspection and supervision; and thirdly, further regulate enterprise declarations. Management, preventing the export of rare earth products in disguise, creating a healthy and competitive environment.
It is reported that in 2013, the export quotas for rare earths obtained by enterprises in Baotou area decreased slightly compared with the number of quotas obtained in 2012. In 2013, Baotou City will further standardize the management of rare earth industries, provide more complete and high-quality services for rare earth export companies, help local rare earth companies to emerge from the predicament, and promote the rational development of the rare earth market.
Pneumatic cylinders (sometimes known as air cylinders) are mechanical devices which use the power of compressed gas to produce a force in a reciprocating linear motion.
Like hydraulic cylinders, something forces a piston to move in the desired direction. The piston is a disc or cylinder, and the piston rod transfers the force it develops to the object to be moved. Engineers sometimes prefer to use pneumatics because they are quieter, cleaner, and do not require large amounts of space for fluid storage.
Because the operating fluid is a gas, leakage from a Pneumatic Cylinder will not drip out and contaminate the surroundings, making pneumatics more desirable where cleanliness is a requirement. For example, in the mechanical puppets of the Disney Tiki Room, pneumatics are used to prevent fluid from dripping onto people below the puppets.
Once actuated, compressed air enters into the tube at one end of the piston and, hence, imparts force on the piston. Consequently, the piston becomes displaced (moved) by the compressed air expanding in an attempt to reach atmospheric pressure.
Although pneumatic cylinders will vary in appearance, size and function, they generally fall into one of the specific categories shown below. However there are also numerous other types of pneumatic cylinder available, many of which are designed to fulfill specific and specialized functions.
