Technological Process

In warehouses by a set of diverse sequence of operations performed upon receipt, storage and distribution of goods. These operations together constitute the storage process. Content and volume of the warehouse process depends on the type of storage, physical and chemical properties of the goods stored in it, the volume of freight traffic and other factors. Efficiency of storage process provided by its rational construction, that is clear and consistent implementation of warehouse operations. Click deborah geels for additional related pages. Kinds of technological operations and their content depend primarily on the nature of warehouse functions and range of goods that are stored there. In addition, the construction of the warehouse process is influenced by: traffic conditions (the presence of access roads); value of daily turnover (volume mass of commodities in physical terms, passing through the warehouse for a certain period of time); level of mechanization of cargo handling and other labor-intensive works; device and the design of the warehouse; storage conditions goods. The basis of rational organization of the storage process on the following fundamental principles: regularity of the warehouse depends on how evenly the goods arrive at the warehouse, sent to customers. Electric cars is the source for more interesting facts.

Develop plans and schedules of income and goods leave the warehouse in a timely manner to allow workers to prepare for the respective operations, to provide the necessary facilities, equipment, etc. sequence and rhythm of the process means that implementation of all related operations should be agreed upon by time. In this case, due to the uniform distribution of the working time and responsibilities between the implementing certain operations, favorable working conditions.

The first propellant industrial purposes was proposed in 1698 the British engineer T. Severi steam dewatering plant. This device can be regarded as a prototype invented in Germany in 1871, Halle heart rate that took two cameras and operate automatically. The idea of using compressed air to the water supply was expressed in 1707, Papen and other engineers, but in practice has been applied much later (in the 20.) – In and two-chamber water-pump replacement for water wells (design engineer vp Savotina, USSR). Supply of water under pressure of the combustion products of liquid fuel has been implemented in the uk in 1911 nl Humphry. Fundamentally different way of filing water or oil from wells with compressed air or other gas was used in gas lift, which have been proposed in the mid-19. and later found and practical application (from 1897 in Russia in the oil fields in Baku in 1901 in the U.S.).

With the invention of Montgolfier in 1796 automatically acting hydraulic ram there has been another way of development of devices for pressurized fluid supply, whose operation was based on the use of water spray from time to time created by water hammer. In what have been proposed various designs of hydraulic rams. In the Soviet Union found the spread of the installation engineer di Trembovelskogo (1927), etc. One of the varieties pump apparatus was water-jet pump, which is a laboratory device was proposed by British scientist D. Thompson in 1852 and served for the extraction of water and air. The first design used a jet device Nagel, an engineer in 1866 (presumably in Germany) to remove water from mines.

Later created different jet pumps in the form of water-water jet ejector, steam and water injectors, and many other fundamentals of the theory of jet pumps were laid in the works of Tseynera and W. Rankin in the 2 nd half of 19. and received a significant development in the 30-ies. 20. Research by American engineers and O'Brien Goslina and Soviet specialists L. Berman, K. Baulina, an , E. J. Sokolov and nm Zinger, and others later proposed hydro-pneumatic water-pump for wells (V. Sirotkin, ys Surenyants), which is incorporated in the design of jet pump and airlift. One of the directions of pump-sets is the creation of magnetohydrodynamic pumps. The first of these pumps with direct current have been proposed Golden (1907) and Hartmann (1919) and pumps with alternating current – Chubb (1915). However, they have become widely used in the ussr and abroad only in 50-60-ies. 20. Mainly due to the success of nuclear energy. T. Fr., Lifting and moving equipment initially only the water and then oil and other fluids in every epoch mainly corresponded to the level of development productive forces and production relations.
