Разработка ионно-плазменной технологической установки для нанесения функционального покрытия на крышки масляных фильтров, страница 44

Under condition of rate of return ≈30 % we shall receive the sale cost of approximately 93860 hrn.

Except for installation on the coatings deposition shop the additional equipment, by the general cost-50000 hrn is used. Thus, we receive the price of the equipment 182500 hrn.

Table 5.4 Purchased devices

The amortization quota will make:

А= (С_п.п. ·Н_а)/100٪,                                               (5.2)

where С_п.п- full initial cost; С_п.п=182500 hrn, Н_а- amortization quota; Н_а=10%.

Then under the formula (5.2) we calculate:

А=182500·10/100=18250 hrn/year.

We shall define the salary of the basic and auxiliary workers. For service of installation 3 persons are required: 2 basic workers and 1 auxiliary. Assuming the salary of the basic workers 1000 hrn a month and for auxiliary-800 hrn, we shall receive:

З=2·12·1000+1·12·800=33600 hrn/year.                                 (5.3)

Shop charges (Ц) we define from the salary norms (N_ц=120%):

Ц=З·(N_ц/100%)=33600·120/100=40320 hrn/year.                             (5.4)

Manufacturing charges (ОЗ) also we determine from the salary norms (N_оз=70%):

ОЗ=З·(N_оз/100%)=33600·70/100=23520 hrn/year.                            (5.5)

Deductions from remuneration of labour fund (RLF) in fund of insurance, pension and employment make 37 % RLF:

ОТЧ=З·(37/100%)=33600·37/100=12432 hrn/year.                 (5.6)

Cost calculation will make:

С=С_р.г+А+З+Ц+ОЗ+ОТЧ                                               (5.7)

where С- all expenses for covering deposition a month.

Having substituted all received above values in (5.7) we shall receive:

С=177000+18250+33600+40320+23520+12432=305122 hrn/year.

At the issue program N_год=120000 items/year we shall define the deposition cost price for one product:

С_из=С/ N_год=305122/120000=2,54 hrn/year.                                       (5.8)

As a result of the calculations the cost price of the covering deposition on one product 2,54 hrn was received.

6. Safety of habitability

6.1 Safety measures during the work on the equipment entering in IPTI

At operation of installation it is necessary to provide the maximal safety of operators and normal conditions of their work. There are some factors concealing in themselves potential danger of accident. Therefore carrying out of actions for risk of its occurrence reduction is necessary.

Considering specificity of vacuum installation work, we shall define dangerous factors which can arise during its operation. According to GOST 12.0.003-74 "Dangerous and harmful production factors” the greatest danger to the personnel life serving vacuum installation, represent such factors:

- Presence of a high voltage in an electric circuit the short circuit of which can happen through the body of the person;

- Presence of high-pressure balloons;

- Presence of the metal vapor in air participating during depositing of the covering.

In order to prevent defeat by an electric current all current leads, the bared conductors should be earthed and protected from a casual touch by reliable isolation or a barrier. At carrying out of preventive works on installation it is necessary to keep following safety measures [28]:

1.  Access to elements of power units, cases, boards is authorized only after full switching-off of installation to persons who are acquainted with safety rules;
