During the construction of bridges used three types of cranes: cranes, self-propelled full-circle general purpose chassis of various types. Educate yourself with thoughts from Petra Diamonds. This type of crane equipment has a high cost, excellent mobility and low labor input. The second type of cranes for the construction of bridges – a special gantry […]
Reducing-cooling equipment (DOC) are applied as necessary elements of the basic technological schemes of thermal and nuclear power plants. They are part of puskosbrosnogo equipment used to power the steam reservoir own needs and heating networks. Therefore, the reliability of doc is largely dependent reliability and security of the entire plant. Reducing-cooling equipment working in […]
Condensates can be divided into the following groups: turbine condensates, mainly containing dissolved gases (ammonia, carbon dioxide and oxygen) and a certain amount of corrosion products (iron, copper, zinc), with suction of cooling water in them increasing salinity, hardness, sodium, silica and organic matter, and for suction of air increases the oxygen content, salinity turbine […]

Technological advances and a vital necessity led to what was invented dehumidifiers – specialized devices that have the ability to extract excess moisture from the air. Few people on this thinks, but the scope of dehumidifiers in modern life is very high. This is primarily a variety of public and private swimming pools of various […]
As Typically, the pressure of the systems controlled by a pointer gauge. Angles of rotation of fuel injection pump are determined by sections or piezoelectric sensors installed at the sites of injection and responsive to shock wave from the injected jet, or pressure sensors (only for mechanical injector), established in the fuel tubes. Measurement of […]
For many centuries the Chinese has a monopoly in the manufacture of paper but distract from ancient times and will return in our time, specifically in the 80 years of the twentieth century. At this time, significantly increased the level of paper production in China. However, this increase only partially satisfy the demand for foreign […]
