U.S. dollar is another name of U.S. dollar. Why is U.S. dollar also called U.S. dollar. The Bretton Woods enlightenment came at the end of the Second World War
In July 1944, more than 300 representatives from 44 countries held the "UN International Monetary and financial conference" in Bretton Woods, New Hampshire, U.S.A., and adopted the final resolution of the UN monetary and financial agreement as well as the International Monetary Fund Agreement and the international bank for reconstruction and development agreement, Thus, the Bretton Woods system centered on US dollar was establishedestablish the International Monetary Fund to negotiate international monetary affairs and provide financing support for the short-term balance of payments deficit of member countries; The US dollar is directly linked to gold, and the currencies of various countries are linked to the US dollar (i.e. "double pegging") to implement an adjustable fixed exchange rate system. Because of the history of pegging US dollar to gold, it is customary to call us dollar US dollar
extended data:
the direct link between us dollar and gold is one of the two main contents of the Bretton Woods system. According to the international monetary fund agreement adopted in Bretton Woods, New Hampshire in July 1944, all countries must confirm the official price of gold of US $35 per ounce stipulated by the US government in 1934, which is the basis of the international monetary system
the U.S. government undertakes the obligation of governments or central banks to exchange U.S. dollars for gold at this official price, while governments of all countries must assist the U.S. in maintaining the official price of gold and cooperate with the U.S. government to intervene when the price of gold is impacted. The direct link between us dollar and gold makes us dollar equal to gold and establishes US dollar's central position in the Bretton Woods system
after determining the basic model of the impeller feeder, it is necessary to pay attention to whether the working environment of the impeller feeder has positive or negative pressure. When there is wind pressure, the impeller feeder must be selected as the air lock type. Generally, there is mechanical air lock, that is, the impeller feeder and the valve body are mechanically finished. After finishing, the gap is small, and the material fills the gap when working, The purpose of wind locking can be achieved. In addition, there is flexible air lock. According to different materials, wear-resistant canvas belt and thin stainless steel sheet can be selected and fixed on the impeller flange, 5-10mm beyond the flange. During the rotation process, the gap between the flange and the valve body can be blocked by the deformation of stainless steel sheet
after the basic configuration of the impeller feeder is determined, the frequency conversion speed regulation can be determined according to the specific feeding range. If the frequency conversion speed regulation is required, the driving motor of the impeller feeder can be selected as the frequency conversion motor, which is equipped with a frequency converter to micro control the feeding amount in the later stage. The normal speed of impeller feeder is generally between 24-43 rpm. When the feeding amount is very small, the two-stage motor can be selected to rece the speed and adjust the feeding.
