power consumption in three years I have made 2 216 166 kW-h., and maximum — 5 444 309 kW-h. On average the enterprise it was consumed by 4 166 469 kW-h. the electric power in one quarter. Change of a quarter power consumption within three years was observed ranging from 211 937 kW-h. to 3 228 143 kW-h. The main electricity consumption the enterprise is the share on the second and third quarters of year. Every year on the fourth quarter the enterprise spends the minimum electric power.

Dynamics of change of the annual mode of a power consumption of the textile enterprise is given in figure 5. The minimum annual power consumption in three years I have made 15 962 583 kW-h. (in 2013), and maximum — 17 792 181 kW-h. (in 2015). On average the enterprise it was consumed by 16 665 875 kW-h. electric power in a year. Apparently on drawings, in recent years the enterprise observes electricity consumption growth.

Conclusions:
1. The carried-out tool measurements, have shown uneven electricity consumption in the hour mode. Also was defined that electricity consumption in night time of day is more than day than time days.
2. The daily allowance of the mode of electricity consumption the enterprise averaged 28 147 kW-h.
3. Dynamics of change of the monthly mode of a power consumption of the enterprise has shown that the main electricity consumption falls on the summer period.
4. The main electricity consumption the enterprise is the share on the second and third quarters of year. Every year the enterprise spends the minimum electric power on the fourth quarter.
5. In recent years the enterprise observes growth of electricity consumption.
6. It is necessary to look for possibilities of the differentiated tariff on the electric power, for the purpose of minimization of financial expenses on energy resources.

Еffectiveness of using by repairable disked extractor and spindles
Abstract: In the article the results of the theoretical research are provided which are about determining of the effectiveness of using by repairable disked extractor and spindles.
Keywords: horizontal spindly cotton picker machine, disked extractors, spindles, harvest.
The developed disked extractors and spindles were installed to horizontal spindly cotton picker machines and they were analyzed as a example in Yangiyul MTP AJ.
Since 2006 Yangiyul OSC branches in Tashkent and Syrdarya exploit on the contract basis 5 "Case-2022" machines imported from USA. Analyzing maintenance and other expenses during 2010 machine harvesting season on 1 hectare annual revenue and the terms of the aforementioned expenses covering is derived with the help of the equation below:
TCT = P =10150 0.089year, (1)
CT E 42785
where: TCT — is expenses reserve recovery time-frame, year;
P — Net profit of the company, year;
E — Overall expenses during a cotton harvesting season, sum.
HSM modernization will increase the annual expense-profit as before because of extreme wear-and-tear disked extractors with elastic cogs were replaced by new ones. It was made certain that the disked extractors equipped with replaceable cogs in "Case-2022" machines should be made of simple St 3 steel instead colored aluminum as in the US, as it will ensure considerable economical and technical benefits [1; 2].
Effectiveness of using by repairable disked extractor and spindles
Net profit made out of this can is calculated with the formula below:
Ax 5 STT( , = CT--= 18000--= 900 sum, (2)
rr («, ^ 100 100 '
where: SJT (M) — the expenses of current repair of modernized reparable disked extractor during the technical service;
C — the average price of a conventional disked extractor, sum;
upm or > '
Ax — division part, %.
As it was previously mentioned annually during the "Case-2022" works the extremely worn-off spindles are being discarded instead of repaired. In that case, the past net profit is calculated as such:
Ey = [(C - Cr )NJA;
Ey = (18000 - 900)40 • 850 = 1453500 sum, where: Ey — annual revenue, sum; Ca and CT — expenses for a new disked extractor and for the repair of worn-off one.
Additional expenditure coverage term is calculated thus:
TKM = = 0.0172 year, (4)
™ 1453500
where: A=714 pieces — total number of machines working in national agriculture, pieces.
Owing to RDE usage the Yangiyul motor-tractor degree of profitability will increase up to 51.6 percent.

where: Cuj — general production expenditures, sum.

Thus, usage of RDE increases competitive ability of HSM by boosting their functional and technological efficiency.
Lightened spindle usage prevents unripe cotton balls from damaging, and falling down on the soil. An opportunity emerged in our republic to create a new variant of HSM that technologically enables an efficient use of automatic cleaning system that prevents hard pieces of soil or pebbles from jamming in the harvester inlet chamber.
Repaired product total cost calculation Total repair cost includes product preparation, sale and other procedure expenses.
Total cost is calculated thus:
Cp = C + Cox + CIP, sum (6)
where: Cc — repaired product total workshop cost, sums;
C and C — overall economical and internal production ex-

penses, sums.
Cp = 3965146.8 + 75075 + 40402.2 = 4080624 sum. Facilities reconstruction project implementation economic benefit:
E = E - EN (C. - Cp )N . / N , sum (7)
