Modern Climate Systems

Climate system today – an integral part of any modern building. Climate control are designed to ensure that would maintain the microclimate in the apartment. Very sprostraneny split systems of all types – whether it is wall (for flats, offices, etc.), tape and konalnye conditioners (for large and technical rooms), multi-zone air conditioning, chillers and fan coils. As well as roof, tower and mobile air conditioners (Monoblock). If you've finally decided to buy air conditioners, and do not know how to choose and where to start to begin with you need to understand to what area should be a capacity air conditioner, and then based on this pick up the air conditioning system. Today's room air conditioners split system capable of providing not only cold air conditioning at home vozduhom.Oni have mass useful for home use functions. Such as function podmesa of fresh air (partial functional ventilation), purification and ionization of the air heater. Air conditioning systems are constantly improved and developed simultaneously with all modern technology and thus constantly updated with new features and modifications and all bolshii all these positive mutations both relate to exactly split systems.

The optimal option of buying the air conditioner is specialized firms that have their own staff of experts on the installation of air conditioners. Buying air conditioner in the shop of home appliances You will have to look for more extra ustanovschikov.Tak as the main sellers prodat.A that would split the system worked properly and securely it still needs to find the right within the parameters of your premises and many other factors can affect the operation sistkmy conditioning. To a lesser extent this apply to mobile air conditioners, but as practice shows, the mass sellers of household appliances have a vague idea about the properties of one-piece (mobile) air conditioning, and the quality of the equipment leaves much to be desired. You successful shopping.

About A Little Fan

Hot summer 2010 has convinced many Russians in the need for ventilation. The once-expensive and accessible enough to a narrow circle of persons, air conditioners, split systems and other ventilation systems are now becoming more available, and the modern market can choose the model that is called "under him." What is ventilation? Ventilation – the process of replacing the air in the room outside. Often, in addition to ventilation, as necessary to Clearing the air of harmful impurities (eg dust, solids), humidification, cooling, or, alternatively, heating the air ionization. That is, create an environment of air, in which a man it would be the most comfortable. Ventilation is the natural and artificial (or mechanical).

The natural use, for example, ventilation of toilets. The main drawback of such ventilation systems is heavily dependent on weather conditions (wind, air temperature), in addition, it becomes useless with increasing drought, that is, unable to cope with the function of ventilation. Mechanical ventilation, however, is different – from the small size hood over a gas stove in the kitchen to great room ventilation (ventkomnat) – in the factories. However, they are united by principle. Fans are different, and can strengthen both indoors and outside. Both have advantages and disadvantages. Thus, external fans do not take up space in the room, then the second more mobile, and if desired, may be moved to a place where they are most needed.

Particularly popular have won the devices that can simultaneously handle multiple tasks, then there is the need for multiple devices is not available. When either the air conditioner is necessary to consider not only the design and the price factor, but technical characteristics of the device. Well established air conditioning and ventilation systems brands already well known throughout the world. The best-known Japanese manufacturers – Panasonic, Toshiba, and rather exotic name – Sharp, Chofu, Funai. In any case, choosing the brands of air conditioning, you get a well-known Japanese quality, fresh design ideas and top-notch equipment. Often, it falls to overpay for a name. Less widely Russia is represented by the European technique and Korean manufacturers. European – Bosch, Ariston, Argo, the best known among the "Korean – Samsung, LG, Daewoo is not necessary to pay special attention if the purchased equipment will be written made in China. Practice use of air conditioners shows that air conditioners manufactured in China, Taiwan or Singapore, is not inferior to similar equipment, produced in Japan, as all production is under the control of Japanese or European technology, and therefore (in most cases) are taken and components. In general, manufacturing in China a few cheaper price of finished product.

Bulletproof Glass

The desire to protect themselves and the desire to protect their property is inherent to mankind from time immemorial. The window is always served vploscheniem opening to the outside world. Glass is – a fragile barrier between the cozy little world of your home and ubiquitous social environment. More than one year left on it to realize the illusory dream of military engineers and owners of banking institutions – to create. Now the worldwide use of bullet-proof, armored protection – it usual for those wishing to protect their property. Bulletproof glass is a laminated block of glass glued together with adhesive photopolymer layers of various thicknesses. There various classes of armored protection. Bulletproof glass is stable when exposed to firearms and safe for human use (by breaking cracks and breaks into fragments with blunt).

Depending on the subsequent use of materials and tasks on a shock-resistant armored glass is classified, bulletproof, safety glass. Due to the thickness and number of glass plates is determined by the stability of the material to the influence of external factors, including mechanical ones. The same applies where the bulletproof glass? Modern architecture and design solutions can be used safely armored glass for conservatories, large aquariums, stairs, ceilings and floors. Purchased from a reliable manufacturer certified bulletproof glass eliminates the possibility of cracking and eliminates the need to install bars on the windows.

Art Casting Models In Sand Mold

Art Casting of models in ground form – this is the easiest way to get castings. Briefly technology is this: on the template (model) of forming the shape of the land is made for pouring molten metal. The shape made by a particular pattern – a one-time: when it breaks notch cast, as created from a mixture of sand and clay (25% of the content in a mixture of clay, 75% – sand). But the very mixture for the mold can be used repeatedly, updating only the inner cladding layer. The template can be made of any material – clay, gypsum (the most acceptable and comfortable materials), wood, plastic, metal. Model can serve itself and detail, if you want to do the same (to restore its original form), then the clay to build up a restored or restored parts missing parts of the initial sample. If for some reasons it is impossible to use as a model plasticine replica of the original, yet spine out is to make a plaster cast from the original (though this is more time-consuming and troublesome way).

The process of obtaining a plaster product model is that the original is placed face up on a flat plate in a frame of wood or other material, with the side frame must be above the copied items from inside and lubricated lather. Gypsum is dissolved in a rich water until a creamy liquid state of the masses. For more specific information, check out Samsung Electronics. In the fast paced original carefully covered with a layer of liquid plaster, causing its wide paint brush, and then pour plaster of Paris to the frame edges. Can accelerate or retard the setting of gypsum: In the first case a supplement 4% solution of sodium chloride, in the second – 1% acetic acid. Next, a plaster mold (mold) is dried at a temperature not exceeding 50 C, treated in kontrrelefe, increase as needed relief, smooth ribs, close up the shell. Before the direct production of cast models cover a 3% solution liquor, and even easier – well whipped soap, that creates a separation layer, and pour liquid plaster. Thus, the pattern is ready, and you are ready to molding.

Investment ring is put on the board submodel, which also put the template or the original. Board sprinkled with graphite, to avoid sticking Facing a mixture that is poured through a sieve to completely cover the model. Densely fill the investment ring to the rim, laying the ground layers and compacting the tamper, and the surplus land smooth bar of special or a flat strip, holding the edges of the flask, and invert it, becoming the second top mold, which zaformovyvayut taper bars – model sprue and riser. Then, removing the upper mold, remove the stones, but from the bottom of the flask is removed template, after which the holes left from the sprue and vent patterns, cut out the template cavity narrow connecting channels. Flasks combine in the same position and pour through a funnel liquid metal that flows in mold cavity, and on another channel, aiming to vent from the mold is displaced air, the shape evenly and completely filled with metal. Specified cast is received.

Mobile Measurement System

Inventor of mobile measurement system is considered to be by Leonardo da Vinci's sketches on which are stored in the Louvre, you can see the sliding mast "yardstick", mounted on a cart drawn by four in which the horses. Two slaves rotate the gate mechanism of guidance, next to the wagon keeper is to compute the coordinates of the points at the top of the mast. Of course, neither of which the practical use of this device at the time could not be speech: a simple means of measurement provides an order of magnitude greater accuracy. The rebirth of mobile measurement systems occurred in the late 20th century, when the level of technology has allowed to begin production of accurate coordinate machines with sufficiently low cost. Today on the accuracy of the best mobile measurement systems approach to fixed, while having almost an order of magnitude lower cost. The following types of Mobile measuring systems: The machine type 'Hand': consists of a base that can be fixed to any flat surface or be based on a portable tripod, and several articulated knees.

In each hinge located Encoders that are sent to computer information about the relative positions knees. Software in real time calculates the coordinates of the measuring probe, which ends with the hand. KIM working area is a sphere with a diameter of 1.2 to 3.7m (depending on the length of the arm), the probe can easily get to almost anywhere inside this sphere. The hand does not have the drive, moving the measuring probe and the fixation point measurement made by the operator.

Special Equipment

Today, it is possible to rent actually any transportation special purpose vehicles. Starting from warehouse equipment to road machinery. Choosing to rent special equipment to be taken into attention, what tasks it will perform and the conditions in which to work. Of these needs will be considered requirements that apply to the technical characteristics of certain types of technology. In some cases, it is worth considering the mechanisms that combine features of several types of machinery at the same time. Rental of cranes, loaders, bulldozers, aerial platforms, excavators and other machinery required in different cases.

In carrying out the work or not long when you need a rare special, whose presence in your fleet is not profitable. Also, special rent when you must have a large number of special equipment for long time or need to make work in a remote location, where the technique is difficult to use personally identifiable or it is busy. With the rental of special equipment you can increase its fleet and perform simultaneously many orders. Just spectrum fleet affects the kinds of workflows that can make the organization! Rental of special equipment – a type of lease, which is divided for rental equipment with the crew and lease without crew, as well as provision of additional services. Rental of construction equipment to avoid buying expensive cars, taking the equipment on lease for a specified period, you can do the job quickly and efficiently, without the high cost of its acquisition. In recent years, such a service as special equipment rentals in Moscow, is in great demand.

It is associated with a significant expansion of the construction. To date, there a huge number of construction projects all levels, ranging from building small houses and finishing construction of residential and nonresidential buildings. It is worth noting that no matter what the scale of construction was not carried out, in most cases facility requires special equipment. You never know exactly what will be needed in the near future, bulldozer, forklift or crane. Therefore, in such cases is very convenient and profitable rental of special equipment. Positive aspects rental of special equipment are obvious. Allocate funds to purchase necessary equipment for construction, it is very expensive and the payback period is much longer than the completion of a specific building project. In other words, purchased equipment, just not able to quickly recoup itself. Withdrawal from leasing construction equipment a lot of pluses. No need to waste time and money on repairs and preventive maintenance, no need to worry about how and where to store equipment during the winter. The next favorable factor is that when renting machinery can always choose the technique which is needed for the job and in a prepared state. Thus, you can always rent the required technology, while at the start, namely the laying of the foundation or the purchase of building materials and finishing final papers. Rental of special equipment – a key to the speed and quality of all types of work. No need to have your own excavator, dump truck, crane or bulldozer, and spend significant funds for the maintenance of machinery, its maintenance and repair. A tech also hold in the state of professional workers able to competently operate machinery. Mainly machinery rental can save considerable time and money.


Weight – 5 kg. Locking device secures the hatch over a concrete slab foundation, brick walls or well, that makes the protected door virtually invulnerable, and in this scenario can not be tearing the whole structure. Designed LLC PG "Finprom-Resource" product has a simple and original design. In the center of the hatch drilled one hole with a diameter of 36 mm, which is a keyhole. Drilling is performed by one worker and possibly on-site installation hatch. With the help of the head, rod and nut by one person lever-hinge mechanism is mounted on the lid.

Lock screw has a buttress thread, which prevents the corrosive "gripe" with the nut. Locking is performed manually using a special key. Key inserted into the keyhole and by rotation actuates the locking mechanism, which includes the levers at his disposal with a concrete slab foundation or brickwork hatch design also allows the key cleaning the inlet of all forms of pollution, making it easier to operate the equipment in all weather conditions. UZKL installed as the roads and on the green zone. Depending on the height of the neck well, the variant with an elongated rod. Saratov colleagues proposed closure device compares favorably with other low weight, its versatility, reliability, ease of operation and low value. By using this UZKL, preventing all access by unauthorized persons in the mine communication cable wells and reservoirs to prevent theft, and ensures the safety of the equipment. When drilling holes use a drill with carbide inserts.

Horizontal Directional Drilling

There are many methods of trenchless: horizontal drilling, piercing, sanitation, etc. buroshnek All these methods are designed for laying pipes under the ground. HDD method takes a leading place among all the trenchless technologies as possible, and in abundance. Advantages of HDD as compared to traditional methods of laying utilities are obvious: speed, less financial and labor costs, the possibility of installation in inaccessible locations other methods, environmental, and security. Most of Horizontal Directional Drilling is used for transitions, which for one reason or another do not open. For example, under natural and man-made obstacles (rivers, wetlands, roads, houses, ecological zones, etc.) More and more use of horizontal drilling for economic reasons: because of the speed pads, no need for improvement, dumping, attracting substantial resources and technology workforce. The preparatory process precedes drilling to complete the organization of work required a team of at least 3 Specialists (not counting part-time workers): the operator on the locator, the operator of the installation of HDD and operator mixing plants, mixing bentonite solution. Pretreatment involves a comprehensive analysis and explore the place of work.

Analysis of soil, abundance of communication and other barriers in the land, planning and calculation of the trajectory of drilling. Prior to the drilling unit is brought to the job on a vehicle corresponding to its size and weight (trawl, semi-trailer or a truck). The vehicle must be equipped similar to a certain angle of the Congress (usually 17-20 degrees). Next to install the system for training of specialized drilling mud is mixed water, bentonite and polymers.

American Welding Society

In many cases, the deposited aluminum can be left unprotected, without the use of impregnation. The use of aluminum alloy with 5% magnesium is a great alternative to coating with paint. This alloy is an effective coating for offshore platforms and components that are on deck. Thermally sprayed aluminum is well used for factory equipment operating at high temperatures. When using epoxy impregnation, the coating can withstand up to 5000S, using silicone impregnation – a higher temperature.

In contrast to the coverage surface of the paint coated products Spramet can be used almost immediately after application. Still less damage during operation will be, if coat the individual parts in the production process that allows the sprayed coating to any part of the product and makes it possible to assemble the product after completion or after the repair. The study of the corrosion process by the American Welding Society for 19 years in 1974, the American Welding Society has completed the 19-year study of corrosion protection, zinc and aluminum sputtering coatings on steel with low carbon content. The results of this study the following: aluminum coating thickness of 0.08-0.15 mm, as with the use of impregnation, and without it, provide complete corrosion protection of the base metal for 19 years in sea water and in harsh marine and industrial atmosphere; Zinc coverage without the use of impregnation should be 0.30 mm thick in order to ensure full protection of the surface in sea water for 19 years. In a tough marine and industrial atmosphere, zinc coating thickness of 0.23 mm without of impregnation and 0.08-0 .. 15 mm using impregnation, provide corrosion protection for 19 years in the harsh conditions of the marine atmosphere exposure, apply a layer of wash solution and add 1-2 layers vinyl aluminum. This will improve the appearance of the product and prolong the life of the zinc coating is nearly 100%.
