Abstract: in article the role of cocoonowinding production and an important place in the total production of the entities of light industry of Uzbekistan is analyzed. And also for the purpose of power consumption determination the separate of aggregates is brought experiments based on silkwinding factory IP Verigrow Ipagi, an equiped cocoonowinding by automatic FY 2000 NT machines of the Chinese production and the specific expense of the electric power taking into account qualitative indexes of raw silk is determined. On the received values of a specific power consumption of machines for each speed of unwinding of cocoons and linear density of raw silk it is given to the recommendation after their use. Keywords: power consumption, electric power, cocoon, energy indicators, specific expense, raw silks.

Аннотация: в статье анализируется роль кокономотального производства и значительное место в общем объеме производства предприятий легкой промышленности Узбекистана. А также с целью определения энергоемкости отдельных агрегатов приводятся эксперименты на базе шелкомотальной фабрики ИП «Verigrow Ipagi», оснащенной кокономотальными автоматическими станками типа FY 2000 NT китайского производства и определяется удельный расход электроэнергии с учетом качественных показателей шелка -сырца. По полученным значениям удельного электропотребления станков для каждой скорости размотки коконов и линейной плотности шелка-сырца даются рекомендации по их использованию.
Ключевые слова: энергоемкость, электроэнергия, кокон, энергетические показатели, удельный расход, шелка сырца.
Reeling occupies a significant place in the total output of light industry enterprises of Uzbekistan. There are 30 filature operating in the country that totally consume more than 4690 thousands million kWh of electricity per year.

These factories are equipped with mechanical machines MMR-10, KS-10, KM-90
(Uzbekistan), automatic D-300B, FEIYU 2000EX (PRC), the SKM-320 (Vietnam). The
composition of the processing equipment differs from plant to plant. Electricity
consumption of filatures counted in total, though for the analysis and calculation of power
consumption we need data for each type of production unit in the development of raw silk of
different linear density [1].
For the construction of the energy characteristics of the specific energy consumption, the
performance of the machine, depending on the linear density of raw silk and reeling speed
was determined by the formula:
„ V ■ B ■ 60 • T ■ C ,, ,1Л
А =-s-4 t / h (1)
109
where B - the number of catchers; T - linear density of raw silk, g / m; - Efficiency factor of time for working machine (depending on the machine downtime due to breaks in raw silk load and other reasons, ranging from 0.85 to 0.95); V- unwinding speed, m / min. Specific energy consumption including quality indicators of raw silk can be determined by the formula:
* = ^-1q9 , (2) т ■ v ■ B ■ 60 ■ c
If we take the specific power consumption of the machine FY 2000 NT equal to 1, the energy intensity factor Cc of the remaining machines in relation to it at the same linear density of raw silk and cocoon unwinding speed for SKM-320 - 1.55 for KSM-10 - 0.177. Thus, machines FY 2000 NT, SKM-320 consume maximum power for reeling, and the minimum at the MMR-10 [2].
Specific electricity consumption for FY 2000 NT ranges from 2700 to 700 kWh / t; for SKM-320 - from 4200 to 1100; for MMR-10 from 470 to 120.
The resulting values of the specific machine energy consumption for each reeling speed and the linear density of raw silk can be used in the electrical calculations at the design and operation.
