Why Refrigeration Equipment Breaks Down ?

Often, owners of grocery stores and sellers of products in the sales rooms face the problem that commercial refrigeration equipment suddenly breaks down. Refrigerators, freezer chests, open and closed refrigerated display cases are no longer cool and freeze sometimes abruptly, most often it occurs in the summer time. One of the main reasons – pollution of the condensate. More information is housed here: Vadim Belyaev. If, however, it will be time to clean, wash, blow, then contact customer service and repair you'll be much less. Indeed, in the data sheet for refrigeration equipment is clearly stated that at a large cross-country people need to be cleaned condensate equipment at least once every two months. This will avoid significant damage, as repairs can cost much more expensive, so try not to forget to clean the condensation of dust, dirt, due to which the refrigerator may overheat and fail. Of course there are more complex breakdowns, so you need to consult specialists at the service of refrigeration equipment. If the refrigerator is not working the light, it is possible to change a light bulb and independently.

Each type has its own refrigeration equipment types breakdowns. If we talk about street cabinets, which cost about outlets that are most often broken closing mechanism. Indeed, in summer, the refrigerator door can open up to 700 times a day, so the arrangements are a big impact, and some parts fail. Outdoor cooling equipment also suffers greatly from the external habitat – moisture and precipitation fall in the mechanisms, the details quickly rust and fail.

Rolled Metal And Its Application

In the modern world very widely used metal products in all spheres of life: engineering and construction, interior design and furniture of various steel structures and frameworks in the chemical and food industries. Rolled metal products are divided into: * Rolled. It is: o circle; o square; o Allen; o fittings; o band; o rod. Scope of long products is huge. It is used in construction and in all industries. Fittings used for building structures made of concrete (reinforced concrete). Circle and square is used as a billet for shapes and sections.

And also for the manufacture of parts for machines – different shafts, rods, bushings, axle and much more. As the circle is used as a billet for subsequent production of pipes. Hexagon used for the manufacture of various fasteners (bolts, nuts, etc.), machine parts and mechanisms. There is also a special kind of drilling hollow hexagons, which is used in the petroleum industry. The band used to produce steel, cutting tools and bent structures (channels, angles). Wire rod is used to followed by wire drawing, manufacture valves for concrete or springs. * Tube rental.

This includes all the variety of pipes (seamless and welded, round, shaped and variable size cross section of steel and cast iron, pvc and non-ferrous metals). Scope Tube rental is also very wide. That pipeline, oil and gas pipelines that serve to transport gases and liquids. This variety of applications in construction. Pipe, with a slight loss in strength, is much easier and cheaper similar-sized solid bars. Just pipes are used for installation of various steel structures. * Plates. o Hot. To obtain hot-rolled sheet at a rolling mill roll out a red-hot steel ingot. Basically this type of sheet used in construction. o cold. Applied in the construction and engineering. For example, the car body is made of cold rolled steel. o profiled. Used in construction as a material for the construction of fences, walls, roofs. * Structural shapes: o beam; o channel; o corner. Beam used in mainly in the construction of various structures. As an overlap in the construction of buildings, supporting structures, bridges, hanging rails and other channels – this is a product of the metal profile in the section which is U-shaped. They are produced primarily by hot rolling mills for long. Depending on the form and method of treatment they are divided into: * Hot-rolled Steel channels, Steel channels * special * channel bars bent steel equal-* channel bars bent steel unequal. Used mainly in construction and installation of metallic structures, slabs between floors. Area, again, is involved mainly in construction. For example, is used to produce various welded frames and skeletons. The modern world is difficult to imagine without the metal in all its various forms and images. Production technology of rolled improving day by day, which leads to increased product quality – durability and strength. Metal acquires special properties – resistance to pressure, aggressive media and temperatures, etc. The Russian metal products can satisfy any, even the most demanding quality requirements.

Annular Steam

The operating principle of psa is based on the known physical phenomena of hydrodynamics two-phase flows, whose essence lies in the occurrence of shock in two-phase flow to disperse the latter to supersonic speeds and then braking the sound barrier. psa comprises a body with a pipe supplying water to the inlet flange of steam. The housing is coaxially installed pipe. Along the axis of the device is installed central body and the steam wand. At the entrance of the device installed base of the central body. The output of the device installed base of the central body. Mixing cone of the mixing chamber and outlet diffuser are implemented by annular gap between the outer surface of the central body and the inner surface of the pipe. The device operates as follows: active medium (steam) through a pipeline attached to the flange enters the nozzle, in where in the expansion process reaches the speed of flow close to the speed of sound, or exceeding it.

Passive medium (water) is supplied to the flange, and further, passing through the annular gap between the edge of the nozzle and the pipe is fed into the mixing chamber. In the mixing chamber is complete ring spray jets of water high speed flow of steam. A thin mist with a particle size of about 1 micron. Area of contact between steam and water flows increases substantially. For example, in one liter of the mixture can get a contact surface of phases up to 2000 m2.
