Powerful robust Far marine diesel engines provide a significant service life to 40 000 machine hours, ease of maintenance and have low fuel and oil. Learn more at: music downloads. Auxiliary and emergency ship gensets are designed for installation on board ships with a class of ms. Operating conditions correspond to the performance of marine diesel generator om when placed in the ship's spaces of category 4 of gost 15150-69. The ship's generator satisfies the requirements of the Rules for Classification and Construction of ships or vessels of the Russian Register of Shipping (PPP) or the Russian Maritime Register (PMC) and come with a certificate of the ppp or the pmc. Marine Diesel allow operation at full capacity within one hour of continuous operation. In this case, repeat modes for maximum power – no less than 6 hours of work for the other modes. The total time between maximum power output must not exceed 10% of the total run.

Ship Diesel allow operation at the minimum allowable capacity for prolonged use. preservation marine diesel generators 6h (n) 18/22 Conservation of marine diesel engine spare parts, tools and equipment made to protect them from atmospheric corrosion during storage in a warehouse and transportation, or on the ship when idle for more than three months. Preservation of products are subject to metal surfaces, including metallic and inorganic coatings. Painted surfaces are not subject to preservation. In the marine environment conservation is to installation site marine diesel engine at overhaul – in designated areas at 288 K (15 C) and relative humidity above 70%. The temperature coming to the preservation of products should be equal to or slightly above room temperature. The room must be isolated from the penetration of any gases, vapors that can cause corrosion.

Marine diesel generators that come on the preservation, should not have corrosion damage to metal, as well as damage to paint, metal and other coatings. All materials used for conservation, to meet the requirements of relevant standards or other technical documentation, duly approved. All of the available surface of the tested marine diesel engine must be inspected to detect corrosion. Detected traces of corrosion on steel and cast iron parts cleaned with the abrasive cloth dipped in oil on aluminum – scraper, cleaned of mechanical impurities, degreased and dried. To the surface prepared for preservation, to touch unprotected hands are not allowed. In preparation for marine diesel engine for the preservation of the following: a) the cooling system free from water, rinse with 5% solution emul'sola and dry. Holes in the pipes shall be plugged wooden plugs, and b) the inner cavity of a diesel engine, control station, guitar valve timing, cylinder bushings and other assembly units and parts, as well as rrp, cover the preservative grease K-1-7 gost 10877-64 or a mixture of working oil with 15 '% of Conservation additives akor, -1 gost 15171-70. The entire oil system required to pump this mixture until it appears from the clearance of friction surfaces lubricated under pressure, and c) the outer surfaces assembly units and parts of diesel, unprotected paints, spare parts, tools and accessories tin grease Dex gost 19537-74, NG-203-A of gost 12328-66.

Planing – is the processing of wood (or metal) with removal of chips being produced rectilinear reciprocating tool (or blank). When planing the same plane of the treated surface and cutting. This method of processing used to produce veneer, packaging boards and rough blanks. Planing is divided into longitudinal and transverse. Click Jack Fusco to learn more. Such separation occurs depending on traffic cutting tool relative to the fibers of the material. The cross-planing is very important from a practical point of view – with the help of his veneer get different textures for wall furniture. Planing wood can be used as hand tools (planes, jointer, chisels), and planers.

In machines for the production of veneer used vertical and horizontal slicing scheme. In applying horizontal scheme knife moves back and forth in a horizontal plane. Harvesting it does not change its position relative to the knife. Horizontal scheme – the most common scheme is planing. When vertical planing on the machines himself knife fixed and static. All the movement makes itself workpiece relative to the knife in the vertical plane. Is to say that veneer is satisfied with the slope of the cutting knife to the axis ridge about 12 grams. Due to the slope there is a reduction efforts for cutting, veneer the output is smoother, reduces the possibility of its bundle.

Insulation – a necessary element of the design of each home. In need of warming the ground floor and attic joists, and often the wall. In frame houses completely determined by the thermal conductivity of the walls embedded in them lagging. Walls of brick to match the requirements of the last visit to thermal insulation of walls should have a thickness of 1 m, the walls are made of wood – 0,5 m (for an average strip of Russia). Since the strength of such walls is much higher than necessary for erection of 1 – 3-storey houses, their thickness and, accordingly, the flow of materials at the walls, can be substantially reduced if the walls are additionally insulated. When selecting a heater should take into account a wide range of properties. In First of all it is thermal conductivity than it is lower, the better insulation to retain heat, the smaller the layer needed to protect home. Hydrophobicity is probably the next most important property of the insulation.

Heaters, with high hydrophobicity, they do not absorb moisture – the main enemy of a heater. When humidity increases, insulation greatly increases its thermal conductivity and reduced service life. In addition, a heater, like everyone else elements of house construction should be durable, fire resistant, and preferably easy. The lower density (specific gravity) insulation, so usually lower its thermal conductivity and the less stress it exerts on the supporting elements of home construction. In addition, it is desirable that a heater was safe to use, easy to use and cheap.
