The Type

Depending on the type of shelves, addition to the standard of universal or basic rack with metal shelves, produce and other kinds of shelving. For example, the use of bread shelves wooden shelves or baskets, in the vegetable – metal sloping baskets in pastry and fruit – small plastic trays, etc. When choosing a rack to check with the seller of its characteristics for several key positions. 1. Dimensions. Height of racks in the proposed configurations can be very different – from 1 to 4 pm The best option is 2000mm in height: in this case to the top shelf easily reaches for a man of medium height. In warehouses, where you can use ladders, or when an acute shortage of retail space, set design height 2500, 3000 and even 4000 mm. Width shelves on average between 800 to 1200 mm.

Obviously, the longer the shelf rack, the lower the price per running meter, because the reduced number of supports, fastener, etc. However, strength characteristics deteriorate: can bend under the weight of the shelves are offered for products. Therefore the choice of the length of the rack depends on the mass and dimensions of the proposed product. The depth of the rack is determined by the width of the bottom of the base shelf 300 to 600mm. 2. The strength of the rack. Maximum load per shelf.

It is determined by such factors as the thickness used metal construction brackets and shelves. Additional indicators are the presence of a shelf bracket and ribs, the connection bracket shelves with stand (tripod). Strength values are indicated manufacturers and may reach 250 kg. 3. Cover racks also plays an important role. With heavy use, a common set of goods in the hard pack surface shelves can be damaged, and eventually rust. Color cover those parts of frame, which will be visible after installation of the goods should not pull the attention of buyers. Traditional colors – bright white, pearl white, light gray, Ivory, warm milk, etc. If the racks are used in the warehouse or the archive, then the color gamma is not important and the question is more about the ratio of the price = quality.

The Water

* Then the well should be located a maximum distance from various sources (at least 30 feet from the toilet, animals and places with manure). * If the area does not dry up, then a well chosen is the highest place. With this arrangement, the possibility of contamination is the most well small, because the laws of gravity will drain all the water from the well. * Well it is desirable to have in the country closer to the place of consumption of water, it will greatly reduce the cost of water delivery. But we should not dig a well in the close proximity to the country house (at least 5 feet from the house).

How to make the well logs from Once dug mine completely, the bottom line the future of the well and pump out excess water. Then set the first frame of the thick logs. In the case of weak soil into the first frame enclose large stones. Vertically installed crown. At first the crown is placed second. For a more dense upper crown docking pressed special wooden hammer blows. The joints between the crowns promazyvayut clay.

Once the crowns are set, the bottom of the pit is filled with sand and gravel layer. To avoid bias carcass, the inner side of corners nailed planks. To ventilate the air inside the well, install a special vent pipe. During the construction of wells in the shallow soils of the bottom of the log house is set in a tent.

Pressure

No matter how complex the hydraulic system, it always consists of various hydraulic units, interconnected pipeline systems. The quality of the data pipeline systems typically have been under stringent requirements, because of their reliability depends not only duration and reliability of hydraulic equipment, but also the stability of the entire hydraulic system. Important These components are the various piping systems weld and threaded pipe joints, which are mounted hydraulic and lubricating fluid system. These compounds are conventionally divided into two groups: terminal and loop-through. First serve for mounting on the ends of the pipe and connected to all kinds of pumps, blocks, hydraulic cylinders, etc.

The latter are mounted along the length of the pipeline and used to interconnect separate sites in the overall hydraulic system. Limit connections to complete cut-metal rings provide quick and reliable installation of pipelines using calibrated (Precision) of pipes. Due to strain a relatively soft material of the pipe with the introduction of a sharp edge cutting ring that runs from a much more durable material, sealing is achieved connection with hose pipes. In these compounds without reassembling the tie-rings and replace the pipe end preparation – is unacceptable. Typically, end-complete connection consists of cutting ring, the terminal fitting (or gon) and cap nut. Corner joints can be used to connect pipes with weld nipples, and in this case, locks the ring does not apply. The most commonly used reference materials are carbon steel, brass and stainless steel alloy. The standard is the use of ordinary carbon steel.

In this case, and end fittings, and coupling nuts have a special plating (Usually zinc or yellow chromate). It is worth noting that the most widely used in Russia and Europe have connections with metric threads and sealing cone 24 . Depending on the job Pressure connections are divided into groups: ultra-light, light and heavy. Properly chosen, taking into account the specifics of a particular hydraulic system, used for repairs, will minimize the risk of downtime and breakdowns hydraulic equipment, as well as significantly increase the safety of staff.

Series

GPI Series oils are designed specifically for hydraulic drives on the experience of firms, "VAZ" and "Fiat" and contain additives to improve performance. Industrial oils with high impurities are recommended only for irresponsible systems. Therefore, any oil must be filtered with a subtlety not worse than 25 microns, oil cleanliness class – no coarser than 12 and even 13 under GOST 17216-71. Keep it should be in closed containers and carefully protected from being hit by dust, moisture and pollutants (especially abrasive or solid particles and objects that could clog the valves and oil lines). At a temperature of -10 …- 15 C should be more viscous oil (AND 20 AND 20A, MGE, etc.) at low temperatures down to -40 C – less viscous (EL, q VMGZ etc.). Recommended grade oils are listed in the technical documentation MPI. The use of other brands of oil should be coordinated with the manufacturer. It should be keep in mind that here and below are the usual (old) designations brands of oils.

According to GOST 17479.3-85 new designation for hydraulic oil, used as working fluids for hydraulic systems of machines was cited above in 1.8,10.1 and 11.10. The design of hydraulic MPI includes a number of special assemblies and components (lip seal, seals, rings, valves, pump plunger pairs, etc.), working under great pressure working fluid. Therefore, the reliability of hydraulic machines, the ability to develop large forces at relatively low weight and high efficiency primarily depends on the failsafe of the listed items from their right of assembly and good condition.

Freight Elevator

Elevator – mode of transport, designed for vertical movement of passengers and cargo. A modern passenger elevator can carry up to thirty people, and mine passenger lifts – up to a hundred people. The ordinary elevator moves with a velocity of 0.5 – 4 m / s, while the high-speed elevators can be 17 m / sec. Freight elevator can move up to 10 tons of cargo at speeds up to 1.5 m / sec. Elevators for residential buildings – an obligatory attribute of comfort and convenience, without which is impossible to imagine today's skyscrapers and conventional buildings. Hotyadaleko not everyone knows how and when they were created first lifts. Now we will tell the story.

Scientists believe the advent of the elevator in 1743. It was then in command of the French king Louis XV, who then passed 33 years in the palace at Versailles was built the first lift. The king did not like peretruzhdatsya and climb to the room of his mistress, located above a floor. However, the prototype elevator, familiar to our eyes, was established more than 100 years through the American EG Otis (1811 – 1861.). This man changed my life in a lot of work – worked in construction and mill, digging coach. In 1852, working on furniture factory, manufactures beds, Otis received an unusual assignment – design a hoist to lift the planks on the second floor. In 1853, the inventor discovered light freight elevator with the emergency brake, which breakdowns quickly in case of a rope.

The Camera

Otherwise, early or later the entire structure may simply come down on your head. But for outdoor unit of a special fixture is required. He, as the saying goes, "stand up on foot." It is only necessary to pick a place for him (when choosing a place keep in mind that the unit is not blowing in the curtains or wall, and stood away from the heat source). While unit is not attached to the floor, but after laying all communications move it from place to place anymore. Thus, the indoor unit You can not install: 1. … Over the heat source (eg, above the battery). Otherwise the air conditioner will work on refrigeration, "before losing momentum" and very quickly goes down.

Imagine that you opened the refrigerator door, and it will be cool not only the camera, but the whole room. He "earn" and fails to end the day. The same thing happens with air conditioning. In addition, the heat coming from the battery room, a plastic housing unit may deformed. 2.

… In areas where devices are constantly working with high-frequency electromagnetic waves (eg, drill, drill press). High-frequency oscillations can "bring down" the chip (CPU) installed inside the air conditioner. 3. … Directly over the bed or place of work, otherwise there is danger always catch a cold or, worse, pneumonia. 4. … Where air circulation is impeded, for example, curtains, etc. The distance to the obstacle should not be less than 3 meters. Otherwise, air conditioning, which maintains the set temperature automatically fails.

Vibrating Pumps Brook Brook

Vibrating pumps differ in design: – depending on water intake (the location of the suction hole) top or bottom – of power: from 180 to 320 Tues – The material of manufacture: aluminum, impact-resistant plastic or There are two shared material – current-carrying wire along the length of 6 m, 10m, 15m or 16m, 25m, 40m. – depending on the regulation of domestic pump, maximum flow without the pressure ranges from 1 to 1.5 m3 per hour . The principle of vibration Pump: The principle of the pump is based on the use of variable current, transformed by an elastic shock absorber in the mechanical vibrations of the armature and the piston. Piston, vibrating, creating a hydraulic shock in the glass. Simultaneously, the valve closes the inlet and the water is forced into the pump discharge nozzle. The pumps are equipped with a rope of nylon (required), which is used for mounting and fastening of the vibration pump.

Rope, as he is from nylon, does not carry electric current, thus protecting the rights in the event of breakdown of insulation from the danger of electric shock. The use of wire rope is not recommended, because the cable is ground lug housing. To ensure the operating parameters of domestic brook vibration pump (for example), we recommend complete pump hose with an internal diameter of at least 18-21mm (3 / 4 inches). Using hoses smaller cross-section leads to an overload of the pump and loss of productivity. The pump on the design is simple: it is not burdened by any rotating elements, no motor, it does not require any serious maintenance (Eg grease), no serious repair. The pump is easy: just having a mass of 4.1 kilograms, it can be transferred into any container (even a plastic bag) and then apply anywhere in any tank, whether it be water (river or lake) well (well) or even an ordinary barrel, and it can be hung on a rope of nylon. The main advantages of vibrating pumps brook: – reliability and durability, in compliance guide operation;-meets Russian safety standards – 100% final inspection of each pump on the performance and compliance with the specs – the best match of price and quality of the pump; – quality of materials used vary according to the manufacturer, but meet the necessary requirements – as required from time to time required for washing the flow of the pump from solids, to include the pump in clean water – the suction hole is located at the top or the bottom of the hull that allows the user, depending on the individual existing water supply, select the desired option.

Constructive Solutions

Attic for installation of need for a couple of cubes of more boards and insulation than ordinary attic. Insulated attic – quite suitable for habitation in the winter with a reasonable heating. Warming loft (loft insulation) Construction attic to a greater extent than the lower floors are exposed to heat loss by reason of the lack of roof attic "thermal pad", as well as on the roof of the attic has a large surface contact with the outside world. Therefore, for the comfort and heat economy requires effective and thorough insulation of the attic. So maybe the attic insulation foam or styrofoam, as well as slabs of mineral wool on the basis of basalt fibers. At higher Attic insulation to insulant impose more stringent requirements, as well as to thermal compaction and its execution. This seal prevents warm air to penetrate through the sealing layer.

Attic Insulation must effectively retain heat at the same time should not "steal" extra inches of space. When the attic insulation is important to remember that the heat loss occurs not only through the coating, but also through the end wall. Therefore, gable houses also need to insulate well in line with modern requirements. Heat loss from the roof of the attic are large enough, so competently executed warming could have a mansard roof appreciable effect. Quality roofing permit with the state of thermal insulation can reduce heat loss by more than 3 kW and thereby significantly reduce the cost of heating homes.
