Abstract

Rationing of specific energy consumption in woodworking enterprises is constructed in ac-cordance with the decomposition of production into the partial operations and processes by types of products and into particular areas (units, shops, enterprises). Due to this fact the operating (by partial operations) and total (by separate manufacturing processes) specific energy consumption standards are distinguished. The purpose of this article is to develop an approach to the energy balance preparation and the establishment of the operating rate of specific energy consumption to perform framed woodsawing operations. Energy properties of the electric drive of saw frames are examined in the direction in which the losses and useful energy consumption are determined by loss factors and the performance of the unit. As a result of research we obtained the analytic dependences between power consumption, specific power consumption and performance of cutting mechanism of saw frames, known as energetic characteristics, and made up the energy balance of a saw frame. The proposed method allows us to express the payload to the unit through the performance – an indicator of evaluation of the working results of the unit, site, shop, etc. The presence of power char-acteristics is a way to the more qualitative approach to the planning of specific energy con-sumption for each standard size of assortments and production. The energetic characteristics of power consumption of saw frames are nonlinear. The basic technological factors and pa-rameters of equipment and raw materials affecting specific power consumption of saw frames are determined.
