ESN and EO of the Heavy Engineering Shop

In the heavy engineering shop, metallurgical, power, lifting and transporting, and other equipment and machines are usually of large dimensions and weight, which determines the placement of production facilities in buildings with large spans and overhead cranes with a lifting capacity of up to 250 tons or more, often located in two or even three tiers.

Machine-building enterprises are sometimes classified according to the weight of their products. In this case, heavy engineering plants include those enterprises in which assembly shops are serviced by overhead cranes with a lifting capacity of more than 50 tons (rolling equipment, heavy machine tool building, heavy electrical equipment, etc.).

The output of heavy engineering enterprises is mainly small-scale, one-off. The product range consists of a large number of standard sizes and types. These enterprises are mainly complex and include machining, assembly, procurement, and auxiliary shops.

New heavy engineering enterprises are designed and built, as a rule, without foundries and forging shops; Main The workshops are specialized, and the auxiliary shops are smaller in volume than before, due to the organization of regional procurement bases, plants for the centralized production of parts and products for mass general machine-building use, as well as regional repair, tool and woodworking enterprises.

In addition to specialization and production cooperation, economic cooperation of heavy engineering enterprises with neighboring enterprises that are part of the industrial sector is widely used. node, in terms of the organization of general systems of transport, power supply, sanitary and technical. devices and other engineering communications, as well as connection of enterprise networks to the networks of the settlement.

In order to reduce construction costs, as well as operating costs at heavy engineering enterprises, blocking workshops and services into large buildings is widely used.

At the new plants, the main production shops (mechanical assembly, metal structures, and so on) are interlocked with auxiliary shops and departments and related industries (metal cleaning, metal coatings, gumming, thermal processing, painting, and so on), as well as with closed warehouses, open crane racks, and small energy, transportation, and sanitary facilities. (transformer substations, pumping stations, electric car depots, etc.).

Facilities with increased fire or explosion hazard (warehouses of flammable materials, acetylene, oxygen and large compressor stations, large boiler houses, etc.) are located in separate buildings.

Electricity supply is the provision of electricity to consumers.

A power system is a set of power plants, electric and heat networks, interconnected and connected by a common mode in a continuous process of production, transformation, transmission and  distribution of electric heat energy with a common control of this mode.

The electrical part of the power system is a set of electrical installations of power plants and electrical networks of the power system.

Electric power system is the electrical part of the power system and the receivers of electrical energy powered by it, united by the commonality of the process of production, transmission, distribution and consumption of electrical energy.

Power supply system is a set of electrical installations designed to supply consumers of electric energy (external power supply, in-plant power supply, intra-shop power supply).

Centralized power supply is the supply of electricity to electricity consumers.

An electrical network is a set of electrical installations designed for the transmission and distribution of electrical energy, consisting of substations, switchgears, busducts, overhead and cable power lines operating in a certain area.

Receivers of electrical energy are apparatuses, units, etc., designed to convert electrical energy into another type of energy.

Consumers of electric energy are an electrical receiver or a group of electrical receivers united by a technological process and located in a certain area.
