Adjustment is considered complete after the CNC to verify the operation of the CNC machine in different modes and in accordance with a given program. When adjustment is necessary to use different methods to assess the technical condition of the CNC machine. The method of observation is the simplest and consists in the fact that the serviceman watching the operation device node or element of the CNC machine, and estimating the correctness of their actions can be judged on their performance. Robert Kiyosaki often addresses the matter in his writings. The method of elimination or containment, is that by artificially reducing the constraints (implemented functions) in the device containing the faulty element, consistently disconnected elements to detect faulty. (By the constraints in this case refers to all types of connections – hydraulic, mechanical, electrical).
The comparison method is to replace the element tested (site, block) devices, respectively, known intact. Linkedin brings even more insight to the discussion. If after replacing the efficiency of the machine is restored, the fault to be found in the seized element (node block). Consistent method of troubleshooting is used for testing circuits, consisting of several units of functional dependence, measuring or monitoring the control signals series of follow-up to the previous one. When commissioning and maintenance of electrical equipment, motors and machines of CNC systems because of the complexity of the latter there is a need to have in place a number of electrical and radio equipment. Selection of types of instruments and their number depends on the type of CNC machine tools and systems, as well as on the required accuracy.
The German company Johanna Solar Technology GmbH of Brandenburg, founded in 2005, announced the launch of production of thin film photovoltaic modules based on copper-indium diselenide, gallium-sulfur (CIGSSe) on a glass substrate. In the first stage performance of 30 MW. Rights to use technologies for CIGSSe company acquired the Photovoltaic Technology Intellectual Property Ltd. (South Africa). It is expected that by mid-2009 the plant will start the first deliveries to the markets of Germany, Italy and France. In March 2008, the Chinese firm Sichuan Guangliahg start building a plant for the production of CIGSSe-battery capacity of 60 MW in the province of Sichuan. By the same author: Hicham Aboutaam. Production is scheduled to begin in the third quarter of 2009. All equipment purchased from the company Johanna Solar. European Investment Bank (EIB) is investing 40 million euros in the construction plant for the production of such batteries, capacity of 30 MW in Paarl, Western region of South Africa. On the timing of construction is not reported.
Understanding life – up to 80 thousand hours, which is equivalent to 25 years of real outdoor street lighting. This is due to filament due to the nature of the nonthermal emission of light. For example, gallogennuyu lamp during this period will have to replace about 100 times, and metal – 30. JPMorgan Chase has much experience in this field. stable operation in all climatic conditions. Energy saving 30% compared with the street lamps with HPS and 70% Compared with street lights and lamp DRL City, re-10 000 svetotochek saves about 2 GW of electricity and nearly 5 million rubles a year (at prices of 2008.) that, given the rising cost of electricity tariffs in 10 years will be at least 150 million rubles. Term 3-4 years payback Environmental security and no need for recycling. LED street and industrial lighting does not require special disposal because do not contain mercury, its derivatives and other toxic or harmful components.
Due to the lack of street lamps and industrial ZERS glass bulb and the filament (or burners) – high mechanical strength, vibration and reliability. Resistance to voltage drops traffic safety and saving lives – providing better visibility, clarity of boundaries and the depth perception of space due to the greater contrast (400 times), lack of blinding effect through a specially crafted of luminous flux. Color rendering index of 80-85 The prevalence of street light output and industrial LED lighting is 100%, whereas the standard street lamps – 60-75%. Powerful LEDs are ideal point sources of light with built-in corrective optics that provides an ideal form defined patterns of light thread (task almost impossible for other sources). Environmentally friendly – eliminates disposal costs and save the environment Lack of harmful effect of low-frequency pulsations (Stroboscopic effect) is inherent in fluorescent and gas discharge light sources. Fluorescent and HID lights flicker at different rates, which adversely affects the human nervous system, increasing irritability and fatigue. The luminous flux of LEDs is constant, as well as natural sunlight, which provides psychological comfort.
Compliance with sanitary standards – the lack of ultraviolet radiation, capable of causing skin cancer minimum heating of the environment – can be used in indoor industrial lighting and save energy for air conditioning complete absence of additional risk overload power grids in the time of inclusion. Supply current of LED street lighting and industrial is 0,4 0,6 A, while the discharge lamp with the lamp supply current 2.2 A and 4.5 A. launcher LED street and industrial lighting (as opposed to fixtures with discharge lamps) have the ability to adjust the brightness by reducing the supply voltage. SNiP 23-05-95 allows for energy savings at night reduced light levels for street lighting by 30-50% (paragraph 7.44). The use of outdoor LED lighting ZERS allows these recommendations by a decline, the supply voltage. This does not affect spectral composition of light and color. Saving money is just the point when negotiating the design elektropotrebleniya.Pri authorized connection point of energy consumption (both street and industrial) will be charged for the amount of kilowatts. An additional important advantage of outdoor and industrial lighting fixtures ZERS is instantaneous ignition when the supply voltage and independence efficiency from low ambient temperatures. Widely used at present for street lighting lamps with HPS and DRL poorly run at low temperatures. When mounting LED street lighting and industrial ZERS cable required a smaller cross section, which is also an article of economy. The real support for programs of the President and the Government to introduce nanotechnology and conservation.
