Peru will build an eco-city of 2,500 hectares that can accommodate 20,000 inhabitants in the desert area near the city of Paragas in the province of Ica.
According to local media reports, the city named “Paragas Ecological Paradise†will use solar energy and wind energy as the main energy sources, and residents in the city will use biogas to cook. To reduce pollution, fossil fuels cannot be used in any vehicle driving in the urban area.
According to the plan, the "Paragas Ecological Paradise" will be divided into three regions: agriculture and animal husbandry areas, residential living areas, and ecological villa areas for visitors to stay temporarily. Local agriculture is dominated by the cultivation of grapes, peppers, jasmine, olives, asparagus, etc., and grape as raw material is the priority for the development of Pisco wine brewing industry. All crops are not allowed to use chemical fertilizers and pesticides to ensure that the products produced are green foods. Livestock husbandry is based on raising chickens, ducks, sheep, and cattle, and a horse farm opened to tourists is set up. These agricultural and pastoral products mainly meet the needs of the residents of the eco-city.
In the residential area, a 30-meter-wide central street is planned to be laid out, and a 6-meter-wide green belt is established in the middle to plant trees that are conducive to clean air. Peru is an earthquake-prone country, so residential circular houses will use seismic technology.
The idea of ​​the "Paragas Ecological Paradise" project began in 2009 when teachers and students from the tourism school belonging to the University of St. Martin in Peru drafted the project during a survey and study in the Pisco region. This huge project is expected to require investment of 170 million U.S. dollars. The Paragas Eco-City Association is applying for assistance from some international organizations. According to the plan, this eco-city will start construction on January 5, 2011 and be completed in 2014.
The compression spring (compression spring) is a spiral spring which is subjected to pressure. It is usually made of a circular cross-section of material, and is also made of rectangular and multi-ply steel, the shape of compression spring is cylindrical, conic, convex and Concave, and a few non-circular. There is a certain gap between the circle and the circle of compression spring, when subjected to external load, the spring shrinks and deforms, storage of deformation energy. Compression spring introduction to compression spring introduction to compression spring characteristics of helical spring subjected to compressive pressure to external pressure provides resistance to external pressure application of household appliances to power equipment pressure spring compression spring parameter compression spring specification compression spring selection compression spring specification parameter compression spring design compression spring fixed mode compression spring calculation compression spring size specification table introduction compression spring (compression spring) is a helical spring subjected to compressive pressure, most of the materials used are circular in cross-section, and some are rolled in rectangular or multi-ply steel. The springs are generally of equal pitch. The shapes of compression springs are: cylindrical, conical, medium convex and medium concave, and a few non-circular, etc. , there is a certain gap between the circle and the circle of the compression spring. When the spring is subjected to external load, the spring shrinks and deforms, and the deformation energy is stored. Compression Springs provide resistance to external pressure. Compression Springs are generally metal wires with equal pitch winding and a fixed wire diameter. Compression Springs use multiple open coils to provide resistance against external forces, such as the weight of the wheel or the weight of the body on the mattress. That is, they push back against external pressure. Compression Springs are generally metal wires with equal pitch winding and a fixed wire diameter. In addition, there are conic compression springs, or conic and linear combination of springs. Compression Springs can be used to resist pressure and/or store energy, depending on the application area. Round wire is the most commonly used compression spring, but there are square, rectangular and special shapes of wire manufacturing compression spring. Wire Springs with compression springs are used for everything from home appliances to power equipment, motors, etc. because they are the desired type of spring. By the load acting on them or their ends being compressed, the compression spring is compressed by the design of the wire in an attempt to return the spring to its original shape so that the load is pushed back. Main application: medical respiratory equipment, medical mobile equipment, hand tools, home care equipment, shock absorption, engine valve spring. Production Design 1. Look at the actual product requirements to choose the spring material. 2. According to product requirements, determine the internal and external diameter of the spring, the number of effective turns, and the value range of wire diameter. 3. The relevant parameters are substituted into the design parameter formula. Associated Standard Gb/t [1] . 2-2009 technical requirements for cold rolled cylindrical helical springs, GB/T2089-94, etc. .
