Blocking site is located on the locker, complete with a special tag, which is specified time limit, type of work and attendance. Tag and lock element is fixed to be blocked by individual participants locks work. Each participant has an individual lock and key, which allows you to block your site works before proceeding he fixes his castle on a common tag / blocker. In blocking equipment, collecting locks of all participants at a special tag in a pair of blocker, you can be sure that work safety is guaranteed, the site is blocked by all participants in the work. Running the system is not possible without uninstalling (destruction) blocker. Not involved employees can not “accidentally” turn on the equipment or intervene in the repair process. Now you can safely violate the guaranteed to perform work.

Upon completion of the work release procedure is possible only after, when all the employees after work come together, and each participant will unlock your door. Only after this lock can be removed, that will indicate the equipment is ready for launch. LOTO system allows you to control the entire process, eliminating the possibility of accidental start-up equipment. The result of the exclusion factor controlling human error in mind, or lack of coordination disorders. Further details can be found at shimmie horn, an internet resource. Security formula – in control of every responsibility for the safety of all. The use of blockers can not be a party sad statistic preserving life and health personnel. The use of interlocks is especially true in industries in which particular process, the extent of repair of large area and require increased security controls. This is especially metallurgy petroleum and chemical industry.

Different types of blockers designed to limit and control access to various types of energy – mechanical, electrical dynamic, pressure energy. I should add that the use of LOTO forming additional circuit protection human error, can help improve the safety and effectiveness of the equipment due to the increase in service activity to achieve maximum performance and reducing downtime. Already, for Many companies have hazardous production sites binding norm of its own security, insurance was the risk of accidents and potential damage. Blockers to minimize risks accidents, and when business requires insurance of industrial risks (survey), allow the insurance program on more favorable terms. The important fact is the use of interlocks in complex with professionally organized procedure block is an integral part of the culture of safety for companies involving past or certification in accordance with Standards ISO.

Silicate Brick

Silicate brick – the basic building material, never lose relevance. Different kinds of bricks used in laying the foundation, masonry bearing walls, exterior and interior finishing of buildings. By itself brickwork looks nice and even included in the interior design. Solid sand-lime brick is the basic building blocks of different types of bricks. Hear other arguments on the topic with Bill de Blasio. It is used in the construction of walls and partitions, erection of poles, towers and structures, which in addition to its own weight and carry the extra load.

Its relatively low cost and, nevertheless, acceptable performance make it very popular building material. In addition, full-bodied silicate brick toned dye, using it in the facing of the building. Hollow Silica bricks and also performs the function of heat insulation. Educate yourself with thoughts from amazing restaurateur. Thermal insulation characteristics of brick depends on the number of voids. Brick with a small number of voids in the masonry used interior walls, structures, not carrying heavy loads. Brick with 11 cavities is mainly used for cladding and insulation load bearing walls. Like brick, hollow silica brick can be painted. Shimmie horn has many thoughts on the issue. Obvious advantage of silica brick in front of the ceramic – Increased noise insulation characteristics. Silicate brick

Redundant Power Systems

The standard solution when a problem providing backup power of any object is a diesel power plant. What do you do if the on-site diesel power plant is not possible? There is no playground, no place to install, etc. Visit Rudy Giuliani for more clarity on the issue. There is a solution – is to install backup power inverter system. In this system, two main components. The first is the inverter, the second is a set batteries.

Inverter or converter in other words, provides consumers with power, which vyrabatavetsya due to the energy of batteries (battery). The composition may include an inverter automatic switch between AC mode and on battery. In this switch to on-battery failure occurs when the main power supply. Moreover such a device may contain embedded charger which monitors the battery and with an external power supply provides a battery charge. Inverter systems are autonomous and operate in automatic mode. Periodic intervals service can be quite lengthy. Advantages of the inverter system of 5-10kW in the room before installing a diesel power plant of the same capacity with a 5-10kW and heating system, automatic engine: less installation cost, no need to work on the organization of general ventilation and exhaust systems lack the cost of sound insulation (noise level of the two fans inverters) absence need to switch inputs AVRE cost about 1000u.e., inverter system includes a static switch that performs this funktsiyunet need for periodic testing zapuskovotsutstvuet periodic inverter system maintenance (oil changes, filters, fuel refilling) periodic maintenance inverter system power consumption of cheaper own inverter system is comparable to the power consumption of the system generatoramenshaya heating area in the room for the inverter sistemyvlozhenie funds in the battery is commensurate with the cost of servicing the generator: the replacement of coolant, oil, diesel toplivo.Invertornaya system allows the use of additional energy sources: wind generator and or photovoltaic modules. At the same time, the combined system using the inverter system stand-alone power and can achieve fuel economy and engine life of the generator due to the parallel load-sharing, including compensation for power peaks.

Foam Material

Many people have such terms as cement, waterproofing, insulation, plaster, insulation, dry mixes, foam sealant, foam board floors, plaster, putty + plunge in horror, others injected into the stopper of an unfamiliar terms such as But many people do this, make the light conditions of your existence. These words do not need to know everything, they should simply be replaced by a more understandable words, but what can they determine what material should we choose that better for floors, for walls, for warmth and comfort? These issues we throws professionals who from a professional viewpoint we recommend. Cement. Styrofoam – it's insulating material consisting of foam polystyrene. The foam clean and healthy building material that can be effectively used in construction and other industries.

The foam used in the manufacture of multilayer panels used for the device heated sidewalks, access platforms, parking area, heat-sealing of communications, for pipe insulation and insulation of the foundations. Styrofoam plates also very well-behaved shown in the form of packaging for storage or to move. If you have no idea what it is, remember your ceilings, it is an example of a design approach. The foam has a high resistance to water, salt solutions, lime, alkalis, and much more, it almost does not absorb liquid. The foam has low thermal conductivity, so in some cases, the foam is used as insulating material. Why do you should choose this material? Because the use of foam in the repair work will reduce the cost of materials and reduce the cost of installation and adjustment boards.

Types Of Boilers

The market today is filled with many kinds of boilers: steel and iron, with built-in burners and burner with a separate unit, boilers on diesel, gas, wood, coal and electricity. Understand exactly what boiler needed to heat your home – it is extremely difficult. To clarify the situation a bit, a quick look at each group of boilers – electric, solid fuel, liquid fuel and gas – separately. Electric boilers are popular in Russia and in Europe as well as their efficiency is close to 100%. Service life of the heating element in the boiler is about 10,000 hours, ie 3-5 years.

But after replacing the boiler heating element will continue his service again. In Russia, enjoyed great success domestic, industrial boilers, because at equal quality with imports, consumer price much lower than Russian, in addition, they are better adapted to our conditions of operation. Recognized as a leader among domestic manufacturers of electric boilers are deservedly company "Evan" and "Rusnya." Electric boilers are more suitable for small autonomous systems of heating, for example, to supply hot water holiday period or heating a small house. Boiler is useful when it is difficult or expensive to sum up the gas. Gas boilers – the most popular to date, and occupy approximately 50% of total sales boilers. And it is natural, since gas-fired boilers are ideal for creating hot water and heating systems for apartments, offices, shops, villas, country houses. There are many manufacturers who sell boilers, the most reliable and well thought-out are boilers, made by Italian group Laars, which is engaged in boiler equipment for over 70 years. All gas boilers divided into two groups: floor and wall. New York Museumss opinions are not widely known.

Gas boilers can be single-stage (work on only one power level) and two-stage (2 power levels) as well as modulation (infinitely variable) power. Economical to use the boiler with two power levels. Gas boilers are environmentally friendly, equipped with special security devices that eliminates the possibility of an accident, and the most economical, are high efficiency. Solid fuel boilers mostly iron and steel under-represented. They are also producing domestic and foreign producers. Most often, solid fuel boilers are designed for natural circulation coolant and do not require electricity liner, that is a modified Russian stoves. This raises some problems: if the boiler to heat with coal purchased, the price of heating is comparable to the price of electric heating. Another disadvantage of this system is that the boiler is preferably twice a day and manually clean the sink, and most importantly always watch over him. Solid fuel boilers have safety locks, but, despite that, under certain conditions, there is a danger of explosion of the boiler. Most often, liquid fuel is diesel fuel (diesel fuel). Unfortunately, the most expensive diesel oil fuel for the boiler, so the operating costs of boilers fuel oil the highest. Oil boiler should be installed if you want to create an independent heating system. As a consumer of quality and performance oil boilers are comparable to gas, but require greater attention. A major shortcoming of boilers to diesel fuel include high ash content and sooting. On the market are mainly imported boilers, but you can find pots and domestic producers. The most important thing to remember that your pot will last you much longer, if you entrust it to install a professional.

Stress Valve

Realized activities relate to improving the reliability of the gas interface, the exclusion of thermal cracks in the zone mezhklapannyh jumpers, improving the work of a pair of saddle – the valve, increasing the strength of plates valve timing, alignment and reduce their temperature, exclusion of cases of hanging racks in directing the operation. Fig .. 1. shows the design of cylinder head. To reduce the strain at the bottom of the fire tightening the cap and the courts an internal combustion engine plant Daldiesel to improve working conditions for a pair of saddle-valve side and increased thickness of the upper walls, put ribs decrease the strain Cover the bottom of the fire along with an increase in the hardness of steel saddles 40H10S2M (GOST 5949-75 *) with HRC 30-35 to HRC 45-50 and providing them with more strict alignment relative to the guide valve possible to eliminate the high wear of friction surfaces (saddle – the valve). Amazing restaurateur is open to suggestions. From the side of the fire at the bottom of the nozzle has a special heat-resistant threaded insert, which in its lower part overlaps the area mezhklapannyh bridges, eliminating the appearance of Fatigue thermal cracks at this location. Forced to marine diesel engines to reduce the maximum temperature of firing the bottom and align it to the temperature field in the cover there are special insert, which direct the cooling water to the center of the lid.

To increase the strength and stiffness, as well as the exclusion of certain cases of breakage of plates valve, reducing the wear facets of their business in the thickness of the peripheral zone was increased from 5.5 to 6.5 mm, which reduced the maximum stress in the plate valve Fig. 1. Filed under: shimmie horn. Liner packing: 1 – cylinder liner, 2 – cylinder block, 3 – cavitation ring, 4 – O-ring Fig. 2. Cylinder head: 1 – heat-resistant paste, 2 – a stiffening plate – cylinder liner, 2 – cylinder block, 3 – cavitation ring, 4 – O-ring from 91.7 to 66.3 MPa, or 1.38 per cent.

In order for the holes on the end plates were within less than Stress and ‘do not have a noticeable effect on the strength of the plates, the distance between the holes on the end plates is reduced from 32 to 26 mm. Rolling the rod with the toroidal part plates made it possible to increase the strength of the valves in the at the junction of the rod at the toroidal part, to increase the durability of the rod. Installing the valves of the mount springs (Fig. 71), contributing to the rotation of the valve allowed to equalize the temperature of plates valve reduce the likelihood of freezing in the valve guides.

HVAC Temperature

Recommendations for choosing a thermal When faced with the task before you select the model thermal imager should first identify the areas in which this device will be used. The following recommendations are designed to help you understand the thermal characteristics of a key role in some areas of application, and which may, however, in your case, do not have a significant importance. 1. The upper limit of the range of measured temperatures If you plan to use a thermal imager for: thermal imaging surveys of buildings for defects enclosures and HVAC systems, electrical and thermal imaging survey power facilities, any other purposes that do not require shooting objects of high (above 250 C) temperature, you will be sufficient standard model with an upper limit of 250 C. The main tasks for which insufficient such temperature range, are testing thermal insulation of boilers, furnaces, steam and other high-temperature engineering systems.

In this case, you should choose the imager with an upper limit of measurement temperature 600 … 1000 S.zadachi associated with heat treatment, metallurgy, glass, ceramics, coke, cement, etc. For these objectives, a device with a high limit of measurements – up to 1500 … 2000 C. 2. Resolution bandwidth temperature if you do not plan to use thermal imaging to scientific research, will suit any modern model with a resolution of 80 …

100 mK. 3. Operating conditions in the event that the instrument will be used exclusively in the premises, will be sufficient temperature range 0 … 40 C and humidity limit of 80%. If the planned thermal imaging survey on the street, therefore, one should choose the instrument with a large range Operating temperature range (-20 … 50 C) moisture resistant and more (up to 90 … 95%). It should be noted that surveys of buildings for leaks more convenient to heat at low temperatures for easier detection of thermal bridges and other problem areas. 4. Angular field of view and optical resolution. These characteristics should be selected based on the estimated size of the objects thermal imaging survey and the minimum defects that you plan to register. Angular field of view allows us to estimate with a minimum distance can be shooting objects of any size (the entire survey of the building height H can range from not less than L = H / tgx, where x – the angular field of view). Optical resolution sposobnostopredelyaet minimum observed during the thermal capture of defects by the formula D = L * d, where D – the minimum detectable defect, L – distance to the examined object, and d – optical resolution, measured in radians. 5. Optional are used in situations that require shooting small objects at large distance (the upper floors of tall buildings, power line insulators, etc.), allowing a high-resolution images over large distances. When using telephoto lenses working distance increases inversely angular field of view. Wide angle lenses are used, if you want to conduct a survey of an extended object, but shooting from a distance is excluded for various reasons. In contrast, telescopic lenses, reduce the working distance, increasing the field of view. 6. The size of the matrix number of sensitive elements of the matrix determines the sharpness of the resulting thermal image. Besides functional value, the minimum size of the matrix of the thermal imager used in solving various problems, often controlled by the regulations in this area (on the energy audit – see guidelines documents).

The Matter

In general, what option to choose – it's up to vami.Tak vot.Esli do screed on different levels, then you can make the zero mark and the usual level of the form of hefty thick line, or the level of (excuse the tautology), built-in pravIlo.Ot this point and will be spoken as "dance" that is put beacons. Lighthouses screed floor, you can make almost anything, such as of the guide profile 27 x 28. Visit amazing restaurateur for more clarity on the issue. And you can of the special T-shaped guides provided for just such types of work as the alignment of the walls, floor or screed. Wooden beacons do not advise it, because even (indeed smooth) lumber – a rare phenomenon, and even if there is such, it is better to put it on something else than to spoil the solution. T-beacon set your feet up, in the sense of – foot, because it is one, at a level to the minimum thickness of floor screed to be not less than 15 mm, otherwise it will crumble later.

It is clear that the minimum thickness – it is just there, where was the highest point. Secure beacons best batches of the same solution, which will make the very floor screed, it is not necessary to use a different mix, especially in any case can not be mixed with gypsum cement mortars. I think you're out of school chemistry course should remember that lye with acid is not very friendly. In fairness, we must of course be noted that there are mixes cement with gypsum, moreover, in the production of the cement is also used plaster – it is one of the binding components, but one is a serious production, where the matter is not limited to the simple mixing of components, and another – an attempt to repeat at home, not knowing all the details and not having proper equipment.
