Gear Pumps
Rotary pumps – pumps it out family "volume of action", which we talked a little higher. As you know, the main working element of the rotary pumps themselves are the rotors. Due to the rotors is forced displacement of the liquid. Shift comes at a time when the rotors, as well as cams and wedges are in motion. It is noteworthy that rotary pumps do not require the intake / suction valve. In addition, it is necessary to note the benefits of the next representative of the family of volumetric pump – is a gear pump. To date, gear pumps are classified into two types: – pumps with external gearing gears – pumps with internal meshing gears before we start looking at the advantages and disadvantages of each let's give a description of the most gear pump.
Gear pumps as well as use the principle of compulsory rotary displacement fluid. However, unlike the rotary gear pump, a different work item – a set of gears that are coupled to each other. One gear is leading, the second slave. Gear Pumps are easy to use and relatively inexpensive. Gear pumps with internal teeth of gears are arranged in such a way that "home" is located inside the gear pinion, while the pumps with an external meshing gears do not give a trace. It is important to say that the gear pumps have several advantages and disadvantages.
The advantages of these pumps include: – High pressure, which can create gear pumps – pumping ability of the various types of liquids, including high-temperature liquid. – Relatively high cost – Ability to control fluid flow to change direction transfer fluid. – The ease and convenience of operation as you can see, gear pumps have a long list of advantages and disadvantages of the two. Then we'll talk about impeller pumps. Impeller pumps have a rotor, which is located on the surface of the blade, which are made of special elastic material. It must be said that the blades are working (spinning) directly inside the eccentric housing. This contributes to the elasticity of the blades, which eventually bend and literally squeeze the liquid from the pump. Impeller pumps are self-priming, which allows them to easily pump any viscous fluid. The next object of our consideration will be the cam pump, which, incidentally, has two rotors. They provide the movement of fluid within the working chamber. In the manufacture of cam pumps much attention is paid to production of housing for the pump. Why? Yes, because it depends on the value gap between the two rotors. It is these gaps to prevent the direct penetration of the liquid inside the pump. Claw pumps are used for food or for making beverages. Sometimes the cam pumps can be used to produce pharmaceuticals. No less interesting in terms of Fluid Handling Solutions is a peristaltic pump. Operates the pump through a special multi-layer elastomeric sleeve. Peristaltic pumps are simple and very efficient design, which By the way, is not afraid to care "dry" method. As well as gear pumps peristaltic have the opportunity to change the fluid flow in either direction. Simultaneously, peristaltic pumps are capable of working with abrasive and aggressive substances that are not important enough. As a result, this article would like to say that the industry pumps are indispensable in the manufacture of various products and materials. That is why today as industrial pumps demand in the industrial sphere.
The Whole
If the original ceiling is painted with lime paint or glue, and later today acrylic or synthetic, then remove the last layer is simple. Put on a ceiling wallpaper glue and cover it with plastic wrap, then there is "pack." Secure the edges of the film with adhesive tape and leave the ceiling at night for of wallpaper paste. Washing and taping the ceiling 1. If after painting the ceiling you do not plan to paint the frame, panels, windows and electrical contacts, they stick with plastic wrap. Then the whole floor covered with a thick cardboard and plenkoy.2. Wash the ceiling with sponges and rags and paint with an aqueous solution of soap. Wear rubber gloves and take care of the eyes from splashes. If you are going to paint the walls, window frames, panels and other, pre-wash them, too.
Fossa and crack 1. First, close up all the large cracks and bumps on the ceiling and decorative elements, since a thick layer of dry longer. In addition, it is possible that it will need to make some raz.2. Carefully scraped (Expansion) all the cracks with a spatula. Then fill in the filler or small srednemelkoy zernistosti.3. After gluing fiberglass seen the slightest bumps, so pre-sand the ceiling to make it perfectly smooth.
Use the sanding block and sandpaper number 100 or 150. Applying 1. Ceiling primed with a brush or roller. Primer (acrylic emulsion) promotes adhesion of the adhesive for the fabric to the surface, because it reduces water absorption in osnovanie.2.
The Trouble
For cold water and the outer pipe made of polyethylene, for installation – PVC pipes, hot water and heating systems to the liner, perfect tubes made of polypropylene. And the price of their significantly lower zinc metal. Of course, as an enlightened man, you know something that the trouble with them, "your brother" (wink friendly plumbing) no less. Yes, and they last for 15 years, then still change. That's go, you poor guy, Lata old system.
This phrase is best to finish his speech and touched gently to offer the master to continue his work. Of course, you can elaborate on and shortcomings plastic pipes. But why scare the innocent? Plastic in the modern large-scale construction is still unavoidable. Yes, after all, is and has its own advantages. With these tubes you do not feel the familiar taste of water and metal rust. And the fact that any plastic has a high coefficient of thermal expansion (that is bursting from its very hot water) can be viewed as a positive thing. Suddenly, you'll want to get acquainted with neighbors, not only with the lower floors, but also from next door? In this case, when the end excuses for dating with matches and salt – safely install the plastic communication. But it will take up most, because if you suddenly the professional plumber will fall, he will be able to calculate this is the "fullness factor".
Then your plastic pipe may never appear in a neighbor's apartment. And the failure of the operation. You can also try to hopelessly well-established plastic water pipe to connect the latest washing machine (it is said that plastic pipes can not withstand temperatures above 90 C, and at discharge after boiling and is 100 C), but then again have to communicate with family downstairs neighbor.

There are "glam-baroque" and "soft minimalism". Designers draw Today my eyes in the 50's – 80 years. They are interested scratched and chipped things with history, vintage items on the shabby …
Reading Electronic Texts
Anyone who even slightly interested in modern gadgets will certainly familiar with this device as an electronic book. Despite the fact that these devices are rather highly specialized, they continue confidently to grow in popularity, although maybe not as fast as we would like to producers. E-book – this is not the same thing as an ordinary handheld computer, there are many differences. The main thing I would like to call – this is e-paper technology used in the device. By contrast, and clarity of the text is not worse, at least, like newsprint. Conventional monitors are not even close to such a contrast can pass. The second advantage e-book – great battery life.
From 8 to 10 thousand turning – a lot, does not it? It would seem that the device simply wonderful. Library with them, and do not need to worry if you forget this time to charge the battery. But is it all smooth? For starters, the price of such poor capabilities to devices at the level of handheld computers, if not the cost of laptops. This cost includes a few more options than just reading e-books. If the communicator – this is two in one, then the e-book you'll need at least one other separate pocket.
Reader is also quite easy to break. A very common failure – a broken screen. A repair of this damage can fly to a considerable amount. But the growth of the market such incidents do not stop. Among today's most popular chitalok are several models – is gaining momentum iPadLbook eReader V3, PocketBook 301 and others. Firmware – that's what distinguishes the main a lot of books from each other. Displays the majority – from the same manufacturer. If you are not so important usability – select a device in appearance. Reading room can make a purchase in a large number of locations. You can go to the store and You can order some online (for example PocketBook 301 can be purchased at pocketbook-301-plus.ru). Analogues of this site abound – just use the search engine. Now gaining (or maybe already lowers) speed reader from Apple – iPad. Today, it is expensive and rather ambiguous looking device on a network many people. You can verify this by looking at the statistics Vordstat from a Yandex. But how many people buy this unit for more than 30 thousand dollars? Many are not sure revolutionary this gadget. But everyone has to choose himself.
Metal Windows And Their Benefits
In the modern window market, there are two main competitors – plastic windows and wooden euro-windows. Metal and plastic windows are so named because the foundation of their window structure is a metal skeleton. More accurately be called their windows made of PVC, reinforced with galvanized corrugated steel products. The advantages of plastic windows: – Durability – guaranteed lifetime of plastic windows for 40 years and higher – Environmentally friendly – plastic windows are absolutely harmless to health. Used in metal-plastic windows is slightly different from the plastic, which is used to make bottles with drinking water and toys. Plastic windows are not subject to external influences, do not emit any substances and practically nonflammable. – Functionality – plastic windows retain heat well, remove drafts.
The ideal insulation – noise level is reduced by an order, you will not hear the street. Plastic windows do not need paint, do not have to seal up every winter, the glossy surface is easy to clean. – Design – any the most intricate designs of plastic profile: square, rectangular, arched, triangular, polygonal, circular. Plastic windows and doors in different colors for apartments offices, country houses, cottages, shops and factories, conservatories, glazed metal-windows of balconies and loggias. Plastic windows – ideal to implement any ideas in interior design. – Wealth of configurations – Aluminum windows can be ordered with a single chamber, double-glass, with glass, filled with an inert gas, with double glazing with energy efficient glass. With the deaf, turning, tilting and swivel-hinged doors. In addition, there is a lamination technology boxes under the tree, and then the street can not be distinguished from the wooden plastic windows. Accessories for plastic windows: Window sills, reveals, mosquito nets, decorative layout and falshplanki, ventilation systems (comb, slotted ventilation, HVAC valve, automatic vent slit), toning and protective film. Euro Windows 2000 – for windows.
Cameras and Photographers
Under guard an interesting point, even an amateur camera can make a beautiful wedding picture, not inferior in quality training. Photographing weddings – it's very interesting work. Amateur photographer, you can always compete with professional photographer. Watch him. Borrow from the experience. Professional photographer at the wedding – that's good! A novice photographer – better! This, of course, a joke. In spite of this, probably, every professional photographer began his career with an equally small camera.
Just before they were different, were a little easier. Were slightly less likely. With the development of modern technology, digital cameras have become more functional. A lot of options. Different modes of photography. Day, Night, Portrait, Sports. Some inexpensive cameras have already come bundled with a flash.
Now every aspiring photographer can feel like a real wedding photographer – professional! And so, today's digital amateur cameras, and now, as well as for professional cameras photographers have the opportunity to change the iso, aperture and bear it. Why do it? You ask. Try to answer. Looking through the beautiful wedding photos, you may notice that some of them there is a considerable blurring background. A small part of the picture very clearly. This clarity in our opinion it attracts. Makes everything more closely and consider carefully the details of this object. The image is so clearly against the background slight blurring that creates the impression of "ringing" clarity. Such strong contrasts of clarity and a little blurry create the effect of expression, and stop the viewer's attention on a single subject, showing us how it is beautiful, elegant and unique. This technique often used by professional photographers at weddings. He reached for wide-open apertures. On the amateur cameras of this effect to achieve nearly impossible. But you can try. Another interesting effect that you can try on an amateur camera – this is the effect of blurring. Or conversely, hardening. Let me tell you about the second, he more interesting. For a start, a little theory. The size of exposure, this time, in seconds, during which the open shutter camera. At this time the exposure of an image on a photosensitive element. If during this time, until we opened the camera shutter, our object photography will change its position, then we get a fuzzy picture is not pretty. How can this be avoided? It is very simple. It is necessary to reduce the time duration of the opening curtains and everything! Usually, all cameras, including professional, exposure is set in inverse units. Eg. If the camera set the shutter speed 30, then this will correspond to 1 / 30 seconds if the set 60, it will be 1 / 60 second, and so on. The larger the shutter speed the less short time we have opened curtain. And so you understand the theory of aging, finally begin to practice. Why is all we need? This allows us to stop the clock and see that in real life you and I do not notice. For example, champagne, flying tube, flying a bunch of brides and a dozen hands that want to catch him, and much, much more. Most often such photographs can only get a professional photographer. With more brisk camera, a photographer at a wedding a little easier to others to catch such a moment. But that is no reason that would hopelessly lose heart and abandon yourself try to make this shot! Very beautiful pictures can be obtained by capturing the moment of collision of droplets with a surface smoothness of water! Want to try?
BluRay
We are now seeing the midst of war formats Blu-Ray vs HD DVD, as in other matters it was in 80 years. XX century between VHS and Betmax. But put aside the war in the background and let's see how it all began … In the recent 2002 global companies: Hitachi, LG, Matsushita (Panasonic), Thomson, Philips, Samsung, Sharp, SONY and Pioneer have conceived creation of a new format than the DVD. At this stage, and there was a split: one side has offered to finalize the red laser (DVD), while the other took up a brand new blue – purple. Subsequently, the modified format red laser will be called HD-DVD, and blue – purple blu-ray. For more information on HD-DVD.
In technology, blu-ray were clear advantages with respect to the opponent – its capacity was 27 GB single layer, the HD-DVD is 15 GB. Also blu-ray supports up to 8 layers of meaning 200 GB of information. Both formats support video in HD 1920×1080, also a blu-ray discs will be able to connect to the Internet through the players and blu-ray recorders and upload the required subtitles, languages, and additional materials to film. The only drawback of blu-ray is its higher cost relative to competitors. Original article is here

Comments Off on Bonding Of Insulation Boards
adminTree
Gluing polystyrene foam insulation boards to the prepared substrate should be carried out by means of adhesives. The adhesive is applied around the perimeter insulation boards stripe width from 40 to 50 mm at a distance of about 20 mm from the edge and some bread diameter from 80 to 100 mm – in the middle of the plate. The number of adhesive composition should be such that after pressing plate area of the contact adhesive layer is not less than 40% of the Square plate. With a flat wall surface bonding insulation boards can produce-Xia for the entire plane. In this case the adhesive is applied to the surface of the insulation board with a notched trowel or trowel with teeth the size of 12 mm.
When applying adhesive to the excess must be removed from the edges of the slab to prevent the penetration of the joints in the bonding plates. Method of attaching insulation boards made of accordance with the P3 to the SNIP 03/03/01 and indicated in the draft of the work. Insulation boards are fixed with ligation of vertical joints tightly to one another from the bottom up from the basement to the eaves or the profile of the roof overhang. Plate applied to the ground, pressed down and finish a long trowel so that it was in the same plane as the adjacent slabs. The gaps between the insulation boards laid over a width of 2 mm should be filled foam. The foam should be given deep, so it will not get into the gap between the insulation boards and the wall. The excess foam after curing medium zayut knife. When designing a building insulation angles insulation board glued on the corner with an overlap of not less than the thickness of a plate, and another joined to it.
This should be provided plates bond series. Speakers of the insulation boards should be cut exactly to the different sides of the angle of turn. All joints with protruding structural elements (balcony slabs, roofs and other parts beyond the insulation system) must be filled with sealant. No sooner than 3 days after bonding insulation boards Styrofoam their surface should be treated with a rough sandpaper.
