Water pressure before umpeu must ensure receipt at the exit of her hot stream (from the loss of water pressure) with the required pressure of water mains. On the pumping effect of psa. In promotional materials, on psa, often stresses such property as an opportunity to heating and pressurizing the water network. There are allegations about the possibility to refuse pump (negative pressure drop). Expert opinion on this issue 3: 1.Ispolzovanie steam injector for heating the cold water steam and hot water in a storage container is possible if the water and steam in their characteristics comply with sanitary norms and rules. 2. usefulness of the steam injector system for training a network of water at consumer substations that are connected to the steam heating systems are not so obvious and should be considered for each object individually.

If the scheme of heating mains water will be used by psa, which combines the heating system water to increase its pressure, the hydraulic and thermal regimes of the thermal system with psa are interrelated. Dr. Hedvig Hricak describes an additional similar source. With increasing (decreasing) the outside air temperature required temperature of network water should decrease (increase) according to the temperature control schedule. This means that the flow of steam through nozzle psa should also decrease (increase), which leads to changes in network pressure hot water at the outlet of psa, and therefore will change its flow. In turn, due to variable water flow, the temperature at exit from the heating system is not equal to the values that should correspond to temperature profiles, calculated at constant flow of water mains.

At the first move of the piston due to the flywheel kinetic energy, stored during the previous operation of the machine, the air is sucked into the cylinder. During the second stroke also committed by personnel of the flywheel, locked up in the air cylinder is compressed to 35 atm. In this case, the heat released during compression, bringing it to the ignition temperature of fuel. At the beginning of the third turn at the pumps injected kerosene. Learn more at this site: Vanessa Marcil. This injection lasted only a fraction of stroke. During the rest of the mass of the gas expanded and the piston communicated to the labor force, which is transmitted through the connecting rod and crankshaft engine.

In the fourth course of erupted products of combustion through an exhaust pipe into the atmosphere. The engine was equipped with a compressor, which is in a special vessel to thicken the air at a pressure slightly higher than the highest pressure in the cylinder. From this reservoir of air through the tube a very small diameter was directed into a small chamber nozzle, that is, the apparatus for spraying fuel supply, to simultaneously fed kerosene. Connect with other leaders such as Jorge Perez here. This chamber is communicated with the interior of the cylinder with small holes, a lockable tip: when the needle is lifted kerosene to drive into the cylinder due to excess pressure in the chamber. Combustion in the cylinder regulated, depending on the force that was supposed to develop the engine or change the length of the intake of fuel, either by varying the pressure in the compressor. The same compressed air was used for the initial start-up the engine from cold. Placed at the top of the engine camshaft with five cams of a controlled valve, intake air, the other – a valve let in kerosene, the third – a valve manufactured products combustion.

The last two cam operated valves, with which let in air pressure in the cylinder during the initial engine start. The first official test of the new engine produced a real sensation among engineers. From that time began the march of 'diesel' around the world. Many firms that previously had not responded to the offer Diesel, rushed to buy him the right to build engines invented them, and this right now costs them dearly (for example, Immanuel Nobel, wanting to build a ship plants in Russia, Diesel paid about 500 thousand dollars). Already in 1898, Diesel, quite unexpectedly, became a millionaire. However, the first engines fired into production, proved to be unsatisfactory, capricious, and often out of order, required more expensive Spare parts. Produce such complex and high-tech machine was not under force many factories with outdated equipment. As in his time Watt, Diesel had to spend a lot of effort to ensure that perfected the manufacturing process of manufacture of diesel engines – to develop new machines to find suitable alloys to prepare specialists. For several years he wandered through Europe and America, visiting factories, which went on production of his engines. By the beginning of xx century, the main difficulties have been overcome, and diesels are gradually gain more and more new areas of applications in industry and transport. In 1900 at the World Exhibition in Paris, diesel engines have received the Grand Prix. Particularly raised the prestige of the new engines the news that the plant Nobel in Russia established a very good issue of ship power plant design Diesel's working for crude oil.

Confectioner's shop – it is the special case when not working technology sales, used for trade in other products (groceries, restaurants, etc.). There are no trifles, rather, depends on them all. You can not just 'put money 'and wait until they' beat off '. Typically, such an approach leads to sad consequences. Pastry display cases, designed to take account of many years of experience pastry departments and a cafe with them.

One of the problems with facing staff confectionery, is the need to move perishable items from the shop windows in the cold room overnight. As a rule, cold stores operating in negative mode and frozen goods. In morning customers who choose to drink coffee and cake, risking their teeth pieces of ice. To prevent this from happening, pastry display cases and maintains the low temperature throughout the volume. For this used instead of conventional glass windows. The powerful cooling unit can easily handle a full load, display merchandise. All that is necessary to the seller, it lay a fresh product instead of sold. Clean and tidy view – that without which you can not submit work of all shop and shop windows in particular. a>.

For ease of cleaning in the window provided by reclining front glass, it can wipe it without removing the goods from the shop window. Design cabinet designed to meet the specific trade confectionery. And a big cake, and a small cake will be clearly visible to customers, because the backlight has all four levels of computations. In case you need to equip cafes or restaurants, as standard equipment is not suitable for some parameters may make a special shop equipment with non-standard features – size, placement of the unit, an unusual lighting, etc. For example, chocolate and chocolate products require special storage conditions – low humidity and temperature, and should be an appropriate trade oborudovanie.Klassicheskie and together with the soft shapes display set the tone interior and underline good taste of the owners. After all, the most important thing for confectionery – creating an atmosphere, a certain charm that people want to go, even if you originally did not intend.
