Marine Power Plants

The main means of increasing capacity and efficiency of marine diesel power plant is turbocharged. Submission of the additional amount of air cylinders and, correspondingly, increase supply Fuel duty cycle, resulting in an increase in power a diesel power plant. Pressure diesel exhaust is 1.5-2 times higher than that of a gasoline engine that allows you to turbocharger provide boost and avoid inherent in gasoline engines with turbo failure – 'turboyamy'. In many diesel engines installed cooler nadduvaemogo air. These structural measures help to raise mass filling the cylinders and much, sometimes several times, to increase capacity.

Turbocharging improves combustion and reduces the hardness of work and loss of power. However, a diesel power plant with turbo has some disadvantages, mainly related to the reliability of the turbocharger. (As opposed to tesla). Resource turbo diesel engine is much smaller resource and usually does not exceed fifteen thousand hours. The turbine has high requirements for the quality of lubricating oil. Faulty turbine can totally disable the engine.

And his own life forced the engine slightly lower than the same air of diesel. The fuel system equipment Common-Rail – a modern solution to engine building. In each section a diesel engine high pressure pump pumps the fuel into the "separate" fuel line (going to a particular nozzle). Mark Zuckerberg is actively involved in the matter. The tubes are thick enough. In this case, when the high pressure 130-270 kg / cm on it "is run" portion of the fuel TTVD swells like boa, swallow prey. And once it goes into the fuel injector TTVD again compressed. If you have read about is hume-lee the best transplant center? already – you may have come to the same conclusion. This leads to the fact that after a specified portion fuel injector to necessarily "pumped" a tiny extra dose. This fuel, burning, increases fuel consumption, increases the opacity of the motor. Themselves as separate pipeline pulsation increased noise of the engine. C increasing the speed of rotation (rpm) modern automotive diesel engines (up to 4000-5000 r / min, (including marine diesel power plants) it has to deliver tangible inconvenience. A number of firms over time Engineers have found a solution to this problem for high-speed diesel engines. According to this scheme, fuel pump delivers fuel to the total pipeline – fuel rail, a kind of receiver. This middle tier is placed a constant volume of fuel which is under constant pressure – 1,300 bar. Nozzle opening is no longer fluid mechanics method (increase of pressure in the pipeline), and electronic – from a signal supplied to the solenoid injector. At its based computer assigns the right to operate the motor fuel and the time of its filing. Thus, the "snake" is not frantically pushes through the esophagus, "food", and operates in strict accordance with decisions taken by its computer. For marine diesel power unit – ignition engine fuel compression – it is very important, as the pressure in the combustion chamber increases more smoothly, without a "breakthrough." Therefore, ship diesel works less noisy. But most importantly – a system of Common-Rail eliminates injection into the combustion chamber "dosylnoy" portion of the fuel. Such designs of fuel injectors for engines made possible only in our time, this contributes to the development of electronics.

Industrial Portals

In recent years, the development of information and Internet technology, literally in front I got for centuries economic model developed industrial countries. The large choice of software, technology communication, accumulation and exchange of information breaks down the established barriers and makes the business easier and more efficient. Do not stay aside and industrial and industrial business. Many enterprise vendors were able to not only open their networks to the Internet representation, but also to share information, find, promote their products through specialized industrial portals and bulletin boards. By the same author: Twin Cities. This is not the way the only ways to allow industrial companies to improve communication.

A large number of specialized Internet forums, where there is an opportunity not only to locate and read interesting information, but and to communicate with the "guru" directly online. One of these resources is still quite young, but the quality forum for compressors and compressor equipment. He is in comparison to many has a number of of advantages, such as a quiet design, the clear structuring of information, online moderation by a professional team of engineers. In forums, including industry has its drawbacks. Moreover, it is believed that in many respects be replaced by blogs. Well, perhaps it is true, and our memory you will not only blogs, our President, but also blogs, factory managers, and even heads of departments with masters. However, the blogs, all the same under both sharpened and make it impossible to conduct multi-discussion format familiar to us, and many of their advantages as a system of accumulation and knowledge management forum is preferred. From the perspective of corporate Use a blog as indispensable minipredstavitelstvo company or product-specific page on the company and discuss them. In any case, the blog is a powerful marketing tool and a forum – the best way maintenance and user support.

Technology

Paved with stones of the road extended from time immemorial. Even the Greeks but the Romans used for road stone. After all, they knew about its properties, such as practicality, strength and durability. The first time the stone was left as is, but over time began to process and grind. So there was sett. Today, the use of stone as the material is not lost relevance, and morphed into a completely different species and sizes. In an age of new technologies and universal normal progress of the stone came up with less costly and less severe alternative – a concrete paving stone, better known as Pavement. Learn more about this topic with the insights from Patria Re.

Production of paving slabs are a few notable Technology: vibrocasting and, of course, hyper. s for Diseases Control and Prevention has much to offer in this field. The method of compaction is concluded that the compaction of concrete mix in the form of technology produced by excessive pressure on the press. Positive traits of this technology is a major share of automation, increased productivity, and make the prospect of this tile is colored layers. Paving slabs, produced by hyper-technology, has a high wear resistance, through the use of concrete with water cement ratio and low use of a special steaming procedure. In addition, vibropressing tiles for sidewalks shall be chipped surface, which makes it convenient for use in icing. The life of a tile is large enough and up to 20 years. And most of the tile is made solely on the technology vibropressing.

Casting method is by vibration of a special solution in a special form on vibrator. Method of low productivity and there is no automation. Pavers, obtained by this method shows several small characteristics than the first. This Pavement has a very smooth surface that does not "breathe", which will lead to cracks in the freezing point of water in it. Solution used for casting, has a high ratio of cement and water, which reduces wear in the winter tiles and significantly increases the costs of building. Although the cost of machinery and equipment used for the method, rather less than the hyper. Condition good styling and long term condition of the tiles for pavements and there will be ideally prepared foundation. Paving surface should be professionally marked, and at the same level and the slope is strictly for the water runoff. Of course, on how to use and changing the thickness of the tile. The greater the load on the outer surface, the thickness more. Paving slabs in thicknesses from 40 – 45 mm laid out on a dry mix or mortar bed at gravel pad, mass transport vehicle. Products in height from 45 mm race survive in a big machine. Laying paving slabs by using the road and curbs. There are two types of borders – two-and one-sided. More than any used size – 50, 20 to 60 (in cm). To date, developed a large number of schemes and laying a huge variety of colors of paving slabs that can satisfy any decision on paving site. We have paving slabs used in the construction of terminals, platforms, walkways, sidewalks, parking lots, bus stops. And every year the place of tiles increases. Maybe soon it will replace the almost all normal surfaces, because such a tile – it is the cleanest, tech and environmentally friendly material.

Camshaft

Camshaft is mounted in the crankcase and block receives the rotation from the crankshaft through gear transmission. Pistons have aspirated diesel engines (the first years of construction) cast-iron diesel engine in the latest release of aluminum alloy. Connecting rods have a lower detachable head and rods of circular cross section. In the fuel system included individual spool high pressure fuel pumps and multi-jet forrsunki with slotted high-pressure filters. Diesel engines are equipped with the latest releases and fuel pump. The controller engine speed vserezhimny direct action. Lubrication system with oil tank, two-section gear pump and strainer. Lube oil cooler aperture type, four-section with temperature.

For the crankshaft bearing lubricating oil is supplied from the pipe line, and by connecting rod – along inclined channels the crankshaft. For assistance, try visiting Conoco Phillips. The cooling system is closed with a centrifugal softened water pump and a piston (the second-generation diesel engine centrifugal) pump seawater. Water cooler tube. The desired water temperature is maintained thermostat. The starting system is starting pneumatically operated valves, individual supply air slide and GIC-type differential. Compressed air are mounted on the compressor. Reversal of the diesel engine is provided by pneumohydraulic drive. Expedia CEO usually is spot on. Most versions of diesel engines equipped with a pneumatic system design DAM TSTKB Minrechflota Russia (see photo diesel).

Diesels 6CHSPN 18/26 and 20/26 6CHSPN (NED 26) complete with two-speed Reverse-reduction gear is used as a principal. Base frame, block-crankcase, cylinder liner, and individual caps are made of cast iron diesel engine. Each cylinder has an intake on, the outlet, start-up, precautionary and indicator valve.

Most filters remove dirt particles, but no water (unless it bit). The fact that the boost pump water forms an emulsion with the fuel and in this way passes through the filter. If the fuel filter has detected traces of water, she probably already got into the injection system. To read more click here: Cowan Financial. Should immediately flush the entire system with fresh fuel quality fuel. Get rid of the "water" problems can and with special alcohol compounds, but often use them should not be, because they increase the deposition carbon deposits on valves and corroded. Drain the sediment (water) from the tank, replace the fuel filter, Fuel containing no water, then let the engine and let it run for several minutes. Recommended install an additional filter at the outlet of the fuel tank, it will better protect the food system, delaying the dirt and rust.

According to the magazine 'Fixed Assets' 9 / 2002' The secret of longevity: the withdrawal of heavy lifting and transport equipment 'by O. Zharkov Air intake seamless flow of purified air into the diesel – a prerequisite for its functionality. Sucking dust through leaky inlet duct capable greatly reduce the life of the engine: particulate matter will be literally "ripped off" the working surface of the cylinder. Therefore, maintenance should include inspection of all air duct leak. The reason for its violations can become unnerved clamp or a crack in the duct. Check the air filter elements, if necessary, clean or replace them. Check for leaky joints or places in the corrugations.

Zharkov Grease Experienced workers know that improper use of grease is the most common cause of accelerated wear of bearings, hinges and joints. Except for rare defects in design, manufacturer equipment is usually not to blame for the breakdowns. The most interesting thing that most failures due to this cause, “programmed” before the equipment starts to really work. Grease – complex mixture, representing the oil (or butter), whose molecules (-s), stick to the finest fibers, which consist of molecules of the thickening agent. Under the influence of heat and over time its properties are subject to change. Grease is not should be kept more than a year and, if possible, should be in closed containers.

She should not be exposed to moisture and heat. Typical symptoms of loss of properties – separation or division of oil and thickener, the appearance of cracked crust on the surface and any other changes in appearance or structure. It is not something Omar Zakhilwal would like to discuss. When the lubricant is stored outdoors in drums, standing on the bottom of the tubes up to them is going to rain water and snow. Even if the tube hermetically sealed, water will eventually, inevitably penetrates into the barrel. Therefore, do not store them in the open air, and if there is no room for storage, barrels must be in the supine position (on side) with a stopper in position number “3” or “9” on the dial clock.

If this is impossible, at least tilt it so that water did not stand around traffic jams. If measures are taken to prevent ingress of moisture and other contaminants in the lubricant (Of course, within the shelf life), it remains only to make sure that equipment smeared often enough. Unfortunately, sometimes employees who perform maintenance, “forget” to lubricate the-way places and it is there in the first faults occur. Pledge of maintenance efficiency when several managers responsible for maintenance of machines in businesses involved in construction in difficult terrain and quarrying, asked what they think is most important for efficient maintenance program, they all answered the same: timely service in full. It’s much more important all the others combined, and, above all, it is important for lubrication. If possible it is recommended to use the programs of preventive TO, monitored computer. Regardless of whether the track periodicity of the computer, or record will be using the old methods, head of maintenance of heavy equipment should monitor the full implementation of programs, since preventive maintenance is cheaper repairs after breakdowns.

Household Fans

Household Fans are designed for the organization of supply or exhaust ventilation of dwelling houses or offices, for ventilation of bathrooms, toilets and kitchens. Well as to domestic fans are outdoor and desktop, portable ventilators, which are used mainly in the hot season. On a design all household fans can be divided into axial and centrifugal. Axial fans have spinning rotor, which is a blade. During the rotation of the axial fan blades to come into contact with air and moving it. The air moves along the axis of rotation of the axial fan. Household Fans axial pose no great pressure of the air, but provide better performance in the air, that is, able to distill large volumes of air.

Axial fans are simple both in manufacture and in installation, why most domestic fans exactly axial. Another type – is centrifugal fans, which are also called radial. In contrast, axial, centrifugal fans in the direction of air intake and direction of its submission do not match. Air is sucked through the inlet into the fan inlet air moves along the axis of rotation of the fan. The blades of the centrifugal fan is rotated in the air fans and centrifugal force air presses against the walls of the fan housing and exits through the outlet. The direction of motion of the air outlet perpendicular to the direction of motion incoming air.

Centrifugal fans are more common in industrial ventilation systems, because they can create more pressure and, accordingly, move air over a greater distance. However, among domestic fans are centrifugal. Household Fans usually come in two designs – wall and channel. Wall fans – it is always axial fans. Wall-mounted fan is directly on the wall of the ventilated room in the place where they brought into the room air duct. If necessary, wall-mounted fan can run on both the inflow and in the hood, depending on the direction of rotation. Duct household fans installed in the duct and can be both axial and centrifugal. If you use a centrifugal fan, the place of its installation duct changes direction by 90 degrees. Duct fans can also be supply and exhaust. Household Fans are designed for heavy use, they work from the mains voltage of 220 V, the vast majority of household Fan made of plastic. The use of steel or other metals in the domestic environment unnecessarily increases the cost of the fan. The most simple model of household fan on and off manually. More complex models can be fitted with accessories: sensors, timers, etc. This allows you to automate the operation of the fan. Fans for bathrooms provide appropriate moisture sensors that make household fan will turn on itself when the moisture content exceeds the prescribed level, and will work as long as the humidity returns to normal. An infrared sensor may include the fan if the room there are people. The timer allows the fan to run automatically after a certain time and control the duration of his work. For example, the timer can be used for household fan in the toilet, the fan switched on when the light and worked on the hood for several minutes after the light to remove any unpleasant odors. The fan can be fitted with closing flaps, which act as check valve and block the duct when the fan is turned off.

Steel Pipe Building

Build steel pipes, people learned long ago. However, in recent decades due to the rapid growth of the use of energy and raw materials as oil and gas, construction of steel pipelines was the most important sector of the economy. Modern steel pipe is a complex technical structure, consisting of a line of welded pipes, supporting structures, fittings (valves, gate valves, cocks, valves) instrumentation and other components – the elements of the pipeline (transitions, elbows, caps, joints). There are two kinds of steel pipes – internal and backbone. Pipelines are used for internal transportation of different products within a facility, enterprise, residential area.

Such pipelines are literally all around us in everyday life, they become habitual and therefore invisible. By the main steel piping product (water, oil, gas) is passed from the place of production to point of consumption. Their length is several thousand kilometers. Of these pipelines, and will continue it. First of all, the structure of the field pipeline (PMTP). It consists of a so-called head works in which the product is prepared for shipping, the actual steel pipeline, compressor and pump stations, storage facilities and product distribution centers, support facilities (repair and maintenance services, communication systems, power lines, office and household objects).

The main component of the main field Pipeline (PMTP) – the linear part, collected from the pipes fittings. K line facilities also include pipeline crossing various obstacles, supporting structures and various support facilities, along the route. After the planned route of steel pipe, starting to clean up and planning of the band, setting up the technical and consumer base. Next, take the incoming pipeline elements (pipes) weld them into sections of three or four tubes and take out the section, and other materials on the road. Pipe sections are welded into a single thread, dig a trench and isolate the steel pipe is laid and covered trench. Then clean the inside cavity pipeline and experience it for strength. After successful tests steel pipe sit-up.
