Best Balcony

Today's designers offer the same wall decoration issue of sex: a brick or stone. If you are not very suitable for the interior, the paint can be painted in a color that you like, well plastered wall surface. Leaving the walls white, you will create the best backdrop for the greenery, flowers, decor and furniture. Directly relevant to the loggia or balcony is a wooden and wicker furniture. Recently entered the fashion of colored plastic furniture. This furniture has many advantages. She's beautiful, light, bright, easy to clean and tough enough.

It is essential that the furniture was compact and did not occupy much space. If the balcony is narrow, it would be the best folding furniture, and the table can be mounted and bolted to the wall. Hang on a table can not even professional. Deck chairs on the narrow balcony look not only beautiful, but they very practical. If necessary, they can be folded, as if there was a desire to sunbathe, then expand the chaise is not difficult. If the balcony overlooking the sunny side, it is desirable to hang blinds or curtains decorated. Because even the most heat-loving plants do not like direct sunlight.

Modern designers have developed a number of blinds that you can easily find suitable for your balcony in color and interior. When the sizes of balcony big enough for it is possible to put a sofa, armchairs, a table covered with a beautiful tablecloth, a small bookcase. To make it more comfortable you can put on a sofa and chair cushions, made from natural fabrics: hemp, tapestries, textiles, linen.

Marine Equipment. Supporting Mechanisms

Engineering staff required extensive knowledge of the theory, design and research methods of operation of these mechanisms and systems. The widespread introduction of the hydraulic actuator in deck machinery led to the following Classification: First team – pumps, hydraulic drives and fans, the second – deck machinery. The first group provides the effect of different purpose of ship systems, including the main power plants. The second group is steering gears, anchor-mooring and lifting devices. Marine steering gears – the most important mechanisms for control of the ship. The importance of destination has special steering gears requirements to their reliability.

Steering gears on smaller vessels are made with hand-driven, in large marine vessels primarily with electro. Ship's anchor and anchor-mooring arrangements ensure the formulation and removal of the vessel with anchors and mooring the ship to berth. This ship's equipment performed manually operated on smaller vessels, with steam, electric and hydraulic, on larger vessels. Ship lifting devices share on cargo winches and cranes. Their purpose is to provide cargo operations at loading and unloading of marine vessels for general purposes. Ship cranes are more convenient and productive for processing of general cargo. Ship's winches can also raise the heavyweights in the presence of heavy arrows and the corresponding rigging.

Also establish special winches, for example, to raise and lower ship's boats and bridges. By lifting mechanisms include container ships and cranes, lifts, elevators and conveyors for loading and unloading of bulk cargoes. A special group are towing winch providing an elastic connection with the ship towed. Marine equipment lifting can have a steam, electric, hydraulic and manual drives. CLASSIFICATION OF PUMPS FOR AN ACTION operating principle pumps are divided into: 1) the bulk of 2) hydrodynamic action, and 3) jet. To pump the bulk of the first include piston pumps, in which the reciprocating motion of the piston provides flow of fluid in the delivery pipeline. Rotary gear, vane pumps, and many others are working on the principle of the piston. To the pump hydrodynamic action include vane pumps with a the main body of the rotating impeller blades equipped. The blades are putting pressure on the fluid transfer energy to it, direct stream. The pumps in the direction of fluid flow divided by centrifugal diagonal centrifugal and axial. This group also includes peripheral pumps and have received in recent years, significant spread on marine transport vessels. In jet pumps energy is fed with the flow working water or steam. In these pumps, the potential energy of the flow of seawater (communicated by a pressurized pump) or potential energy is converted into steam nozzle into kinetic energy. Therefore, the workflow enters the suction chamber device with high-speed carries (suck) water or gas from this chamber through a diffuser and a mixed stream out of the machine is keen to rail. By the ship's pumps to according to their purpose, must meet certain requirements Register of Russia, concerning both the design of pumps and their drives and their parameters, flow rate and pressure.

Welding Semiautomatic

Welding semi-automatic with high productivity compared to manual metal arc welding with covered electrodes. Creation of welded structures with high technical and economic performance is directly associated with properly chosen method of welding. On how to correctly select the welding material and welding semiautomatic type depends on the quality of welded products. Recently, the welding industry increasingly are widely used welding with semiautomatic welding. The main criteria for choosing the semiautomatic welding are: ease of maintenance welding semiautomatic continuous duty load semiautomatic welding, semiautomatic welding mobility; possibility of quick and easy replacement of wire and the burner (this is ensured by the construction of feeder semiautomatic welding) quick setup of welding semi-automatic, semi-automatic welding Ability to work in a variety of conditions, semi-automatic welding is an arc welding device in which the welding wire is fed automatically by the feeder, and the formation of a weld is a welder-operator manually.

A distinctive feature of semiautomatic welding is its versatility. Welding semi-automatic welding and are used for mechanized welding. To perform specific functions equipped with semiautomatic welding torches of various kinds. Divided welding on semi-groups may be on the following criteria: At the type of electric power supply welding semi-divided into single-phase (220V) and three-phase (380V), At the type of welding semi-automatic layout share on single-hull model with built-in feeder and control equipment and a model with an external feeder and / or remote control devices; At the wire feed welding method can be divided into semi- pulling, pushing and pulling, pushing, The type of regulation of wire feed speed semi-automatic machines are divided into a model with a stepwise, gradual or mixed control; At cooling type torch welding semi-automatic divided into a model with natural or artificial cooling (air or water / gas, respectively); By way of security experts define the arc welding semiautomatic following categories: for welding flux for gas-shielded welding, welding wire without special external protection, and universal; At the wire type semi-divided into semi-solid steel welding wire, soft wire, aluminum alloy powder (self-shielding) wires, as well as universal models By type semi-automatic feeder can be divided into semi-automatic with one drive pulley and a few, should also be noted that the welding semi-automatic can be performed both in the form of stationary systems, and on the welding mechanism (in a figurative or trolley mounted), which moved during welding. Modern semi-universal, reliable, provide high speed and efficiency, as well as compact.
