Wood splitter, as its name implies, is designed for splitting wood. In the above article woodpile machine is called a machine that performs operations trimming and splitting wood. The principle of operation of typical next machine. The log is set on the input conveyor belt moves it to the side facing machine. Facing machine cut churbak, who falls into the chute.

Cylinder push churbak to splitting knife. Churbak falls on the knife and break into pieces. Available in the woodpile specific machines that use a different principle. Suppose, Palax 55, which first churbak saws off of logs, then manually installed opposite the facing of the wedge. But the performance of their much lower. There are machines using the guillotine cut a device.

However, ergonomics, performance and cause serious resource doubt. In a typical machine woodpile trimming is performed using a disk or a chainsaw. Machines that use the circular saw, have a great performance, do not need a daily podtochke saw. But their value above. In contrast to the Woodchopper (Cleaver), woodpile machines have more opportunities to install auxiliary equipment. Racks can be installed for the supply of logs. The design of machines allows the woodpile set the input conveyor. Palax machines originally equipped with them. Also very convenient to work with vygruzhnym conveyor. Classification woodpile machines. By type of blade: – Machine with a band saw – Machines with circular saw, for maximum diameter of the split wood: – up to 25 sentimentality – sentimentality and 35 – to 40 sentimentality – over 40 sentiment, by Type of drive: – Drive a tractor – from the electric motor drive – Combo (Tractor / electric motor) – Diesel; Control devices: – Mechanical – Hydraulic. Manage. Apply two basic principles of control devices: mechanical and hydraulic. Mechanical represent a system of levers lifting / lowering of saw blade, adjust the length of churbaka, dumping logs into the chute for the split, etc. In machines with hydraulic control levers are used instead of joysticks. Working with joysticks easier. But this appropriately reflected in the price. Performance. Productivity tools woodpile higher than that cleaver. And, actually, it's more predictable. The feed rate is constant at the bench. This reduces the human factor. Assistive devices. For energy efficiency possible use of assistive devices. First of all, feeding and storage racks. Also worth noting is the system for cleaning and packaging wood. For machines with diesel engines running in cold weather, reasonable fuel heaters installation.

Pro Drawing

cat June 28th, 2015 by Virtual Keeper

Drafters disappear as a class. Why in our ability to write time drawing characters, show the dimensions and sections, draw the main lines of the drawing? Driving a T-square, wash, wipe up the holes? Blade 'Neva', remember? A redraw again, ate something wrong, huh? All technical drawing valilos on our shoulders. Yes to any shoulders? Log dumped on his head and swung it up to date figure. It has now become much easier. Oh, God, thanks for the computers, for the mega programs that you gave us.

Programs do much more. They have the property – quick, we love them, they make it easy. Now we all can. Now each of us can draw without any difficulty pairing the two circles, smart – to design a car, but whatever. And time? Time decreased markedly for this robot. There is no need to plot the bar pretty dotted line, draw a frame with the main inscription, biting a pencil at aerial thoughts. We have a screen and mouse. They tell us replace dozens of tools for drawing.

Convenient, is not it? Remember their college years. Nachertalka. 'Sign it to me, and me, about me not forget? You're beautiful sign! ". Of course, the beautiful signature girls. Everything was done quickly and to couples. As is usually the students. In high school we were taught a good drawing, and from there learned so beautifully display bukovki. I noticed a group of such was not enough, I have one body, with very pretty eyes – she asks, as many as two people. We served a couple of classmates. It was easy. But his thoughts still went to, how do I draw complex drawings, but they will be, I know it's a-go-go time. To the surprise was the 1st course, and then the 2nd. The teachers we were allowed to draw everything on your computer. This is convenient for them and us. The first program, which I learned was AutoCad. Then there was the Compass program 3D. And I am astounded by made from spent time for it. We simplify your stay by new technologies, they save us time, and the impact is much greater. Cons as always. Forming the drawings in the programs, we forget to build practical skills. We do not think about how to divide the circle into 13 equal parts, all make the program. Drawing the program easier and mental work, but without the brain we do not develop, or at least less develop.

The Glass

Of no small importance in the window system has fittings. Hardware – this is not only window handles and hinges, but also many other pleasant things that can make our life more convenient and comfortable. For example, additional protection against hacking, mikroprovetrivatel allowing leave a small crack to fresh air lifter, the fuse erroneous opening and much more. The company uses its windows fittings German company Siegenia, product quality is very good score for both domestic and foreign experts. In 2003 Siegenia offering newfangled color line of accessories – 'titanium-silver', which is more generous than those already familiar golden.

In addition to the standard equipment now includes such components as "basic security" – the special pins that prevent the doors from the outside by the raised arm and the lifter – promotes ideal location in relation to the sash box windows. And, of course, choosing windows play an enormous role themselves windows, the optimum thickness – 38 mm. Double-glazed windows have a high thermal and sound insulating properties. Due to tightness in the gap between the glass does not fall moisture and dust, not deteriorating light areas. Double glazing consists of two or more panes and spacer with desiccant. For the production of glass, you can use almost all types of glass. The choice of glasses depends of the requirements for a particular wooden box.

It is also important to correctly identify the location and orientation of the glass with special properties in the pane. For example, in the case of energy-efficient glass surface coated, usually located inside the glass. Sunglasses are recommended to set the glass as the outer glass. The existence of people remember slopes (Or know) only during the repair or replacement of windows. Slope – a plane between the wall and immediately a window. Ironically, around the slopes of serious passions simmer. Paradoxically, the shortcomings of old windows is a guarantee long service plastering slopes. In the gap little by little ash pit, and the slopes were gentle intermediate temperature zone. In modern wooden windows sealed almost perfect, and when you open the doors for ventilate the cold air outside 'falls' to warm to room temperature, slope, and it cracks. Must be strict compliance with the technology and the use of fairly expensive finishing materials to protect the slope from the cracks.

Quantitatively Reliability

cat December 9th, 2013 by Virtual Keeper

Accordingly, when evaluating the performance of lamps are the most important: energy efficiency lamps in a given region of the spectrum efficiency efficient lamps for the corresponding effective radiation detector output lamp radiation effective flow, as measured by the level of response receiver – dimensional value, measured in special units, chosen to evaluate the response of the receiver; kmax (h)-value of the maximum spectral sensitivity of the detector (dimensionless quantity). The work of the light source in any real lighting Installation is associated with a number of devices that provide normal operation of the source, the radiation source in redistributing the space for the best performance of the receiver and the system realizing the energy receiver. In all these devices tend to have the energy loss. So depending on what part of the flux or effective flow to a part-consumed power is, it is possible to obtain different efficiency characterize the transformation of the energy of a device of lighting installation. Reliability – ability of an object to perform all specified functions under certain operating conditions within a specified time at conservation values of key parameters in a pre-established limits. Reliability – a complex property, which consists of a combination of properties: reliability, durability, maintainability, safety.

Quantitatively Reliability is measured by a number of indicators (for more details – see GOST 27.002-83). For sources of optical radiation the most important indicators of reliability are the types of tenure. Full term of service, or duration of burning lamps is the total burning time of commencement of operation or testing of hours until the total loss of efficiency, such as incandescent lamps because of burnout thread in discharge tubes due to loss of ability to light up, etc. The useful life of lamps is the total burning time of lamps in hours from the start of operation or testing prior to the departure of one of the parameters that determine the appropriateness of the use of lamps of this type, the specified limits, for example due to reduced flow or brightness below a certain limit for lighting lamps and irradiation or inability to use special discharge lamps of high-brightness light-optical devices in due to the instability of the arc, etc.

Conditions for successful mastery of technical skills are the ability to read blueprints and knowledge of the rules of implementation and design drawings. Drawing is one of the main carriers of technological information, without which no do any production. Development of hardware and software computer technology led to the fact that when dealing with the computer main carrier of information is the image. Computer graphics is the most widely used in various fields of science and technology, economics and management in industry and in the learning process. Along with the improvement of perception allows computer graphics to simulate the on-screen display studied processes and phenomena, as well as create processes and objects. There are currently a lot of specialized software graphics package with which you can create pictures, drawings and blueprints.

In order to master them in addition to knowledge of programming necessary to own the device engineering graphics. The use of modern computer graphics tools on the basis of possible bases engineering graphics. Engineering Graphics – discipline required for training of technical specialties. It teaches methods of image and the general rules of drawing. For a specialist to address these issues is not an end in itself but a means to design, as well as the development and implementation of design documentation. In the study of computer graphics in the graphics system, "Compass" must learn to input and Output from the session of the program. Then learn how to open an existing document and create a new one. Further study should be the main interface elements "Compass" to get acquainted with the basics of graphics.

To learn how to construct drawings of details in two forms, you must learn the basic types of anchors and their use in specific situations. The basic techniques for building and editing of geometric objects, the use of auxiliary constructions to create more complex drawings of details. After examining the construction of chamfers and fillets, symmetry and truncated objects, hatching and dimensioning, you can create a working drawing in three parts projections. To apply this classic 2D technology and drawing on which the design is through projection – flat maps of the object (diagram Monge). Here, a graphics system "Compass" is role of e-Kuhlmann, automating graphic part. The knowledge gained on the construction drawings in the "Compass" apply when the course and degree projects.
