The method is based study on particle size and chemical and mineralogical composition of cement, depending on the strength parameters of cement on the ratio of the size fractions of 0-40 micrometers and 40-80mkm and more – in manufactured according to the traditional technology of cement has a particle size and 200 m. Experiments have […]

Noise is a major source of violations of the comfort of staff of the enterprise, located directly next to the operating compressor equipment. Therefore, often accounting noise characteristics needed in the design, selection and installation of compressor stations. What are the sources of noise? The cause of the noise is the sound waves produced by […]

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 […]
