Glass – an amorphous substance consisting of oxides of silicon (the majority), as well as sodium and other elements. Its production is carried out by boiling in glass furnaces and the subsequent spill on the surface molten tin or punching – depending on what items to get. Glass is widely used in various industries: glazing of windows, furniture, construction of a packaging for liquids, create individual interior decoration. This material does not hinder the passage of light with sufficient strength, but at the same time and high fragility. Therefore, for a competent and effective glass treatment requires special tools and equipment. Glaziers an indispensable tool for cutting glass is a glass cutter. And if the choice was not rich before, now we can just get lost among variety of models.
Diamond glass cutter glass cutter very first of a tool, a work element is a small diamond. Such a model and now considered one of the best, not lost relevance even emergence of modern high-strength materials. Diamond is securely fastened to the tool holder using silver solder, which provides the necessary strength. Holder is slotted so as to make it easier to break off the narrow strips of glass, and wooden handle for ease of use with the tool. Diamond glass cutter can cut the glass sheet thickness of 10 mm and the "mileage" is no less than 10,000 m. At the cutting edge dulled a tool to We introduce another. Locking screw on the tool holder elevate and rotate the blade at 90 and then fixed.
The most rational viscosity before jets 2-2,5 VU, in which the terms of atomization of heavy fuel oil are approximately the same as when operating on distillate diesel fuel. Fuel systems of diesel engines operating on heavy fuel, usually provide two versions of the main engine: start and operate on heavy fuel, start on diesel fuel and switched to heavy fuel. Start malooborotnyh diesel can be produced on srednevyazkom Fuel type diesel fuel or diesel, medium-speed – only on diesel. In all cases, the ship entered the port of 1 to 1.5 hr diesel must be translated into diesel fuel for the complete cleaning of the injection system of heavy fuel oil. To The diesel engine on heavy fuel heater, filter and piping connecting the pipe to the fuel NVD, warm. Then let the fuel pump is self-contained to create the circulation of fuel through the mixer elements fuel supply system back into the mixer. In the presence of the connecting pipe between the heater and piping from the fuel return line to the mixer pump NVD Table 1 Temperature heating, C The fuel in the fuel tanks in the slop and supply tanks to the nozzles for the separation motor fuel DT Bunker oil F5 Fuel Gas turbine fuel DM 5 5 20 15 50 50 70 50 65 70 90 70 70 Not is separated 105 60 fuel system is possible through this tube. The fuel injector is purged, which creates a few high blood pressure in the pressure pipe as long as from the pre-open air outlet of the nozzle starts to leak fuel.
Then how long an instrument, how comfortable they will use and what the results will be working with them, depends on whether selection is made. So, what do you need to look for when buying power tools? All the electric is divided into two types: professional and amateur. The differences between them are significant and technical characteristics, and in terms of price. Professional tools designed for continuous operation and regular use. In connection with this power tool in such high requirements, it goes through many trials and tests, excluding the possibility of overheating and in the course of a long continuous use. Amateur tool – does not mean that it is not quality. He simply is not designed for long lasting stress. But if they are not forthcoming, then spend money on a professional tool has sense.
Distinguish between professional and amateur instrument is not difficult. The first can not be multi-functional, has a high price, the body is made of aluminum alloys. A number of manufacturers to certainly avoid any confusion, the distinction between these two groups are also color. The next thing that you need to pay attention – this type of instrument by the method of supply. Mains or battery? As in the first and the second has its advantages and cons. What good is a network tool? Well, first of all, of course, that does not need to be recharged. This is good in the long run. But the minuses here, perhaps more. First, be aware that import tool must necessarily be designed for use in Russian networks.
