Ordering Flowers Online

Order a bouquet over the Internet – a very good solution for the business person who, on the one hand, limited in time, but on the other hand, wants to be sure not to lose face in front of the target, because the fresh quality flowers are collected in the composition of a professional florist. The accelerating pace of life presents new challenges and offer new ways of their solutions. Not surprisingly, order flowers over the Internet is becoming increasingly popularity, because this method helps not neglected by their relatives, even in the absence of free time. A stylish, beautiful bouquet donated by a business partner undoubtedly contribute to strengthening business relations. In addition, if more recently, this possibility was available in only a few major cities, geography is now considerably expanded. The collected songs of professionals will deliver virtually any point on the globe as soon as possible.

The growth in demand and supply of birth – is already filled with lots of ooiao sites offering flower delivery in Russia, CIS, Europe and the rest of the world. Some are the same further and offer the opportunity to order as sweets, soft toys, candy bouquets, fruit baskets. However, the most ordered are still flowers, because it is truly a universal gift, who will be glad to get on holiday the vast majority of people, and, incidentally, contrary to popular belief – not just women. Flowers – perfect assistant willing to talk about their feelings, to congratulate significant event, thank or apologize. In addition, the order via the Internet and offers features not available with gift live – the donor's anonymity. If you want to intrigue recipient, or, conversely, to make this gesture was understood only two of you – delivery of your order by courier as well as possible help in this. Of course, the absolute leader among the flowers are roses, but fans exotics also always find something to your taste – for large sites is a wide choice of various colors and compositions. In addition, as a rule, they are always happy to go to meet the most unusual customer requirements and, therefore, the choice is limited essentially only a flight of fancy client. That's why a growing number of people have benefited or will benefit from this service in the near future.

Reciprocating Compressors

Reciprocating compressors consist of the following elements: a working cylinder, piston, injection valves, crank mechanism with the crankshaft. The principle of reciprocating compressors simple: first, by the action of a crank mechanism to the piston of a reciprocating motion of the latter. In this case there is a scattered pressure and the cell enters the air (gas). During the return piston pressure increases, and when the pressures are greater than the drag force springs, clamping the discharge valve, is pushing air (gas) into the duct. Feature of the piston compressors is the presence of air or water cooling, which prevents the spontaneous combustion of lubricating the compressor. Reciprocating compressors are divided into several basic types: single-cylinder; multiple cylinders. Depending on the layout of the cylinder compressors are classified as: vertical, horizontal; V-shaped; W-shaped; L-shaped. In smaller compressors most common V-shaped pattern.

In large double-acting compressors most common L-shaped arrangement of the pistons. In addition, reciprocating compressors compressors are divided into single-or double-acting. In single-piston piston compressor runs only on one side, and, respectively, in the compressors of double action – the two sides. Depending on the compression process are divided into single-stage compressors and multi-stage compression. One important feature of reciprocating compressors is the system drive. Depending on the type of piston compressors are distinguished: direct drive, belt-driven. An example of modern reciprocating compressors can be used compressors Remeza , providing high efficiency and are characterized by reliability in operation. Screw compressors Screw compressors, along with piston received also widespread.

This is due to the following factors: the number of pairs of screw compressors friction is minimum (impact on life); screw compressors are more resistant to overheating than, for example, Piston, rotary screw compressors are more simple to use and install; screw compressors are economical. The presence of such positive qualities screw compressors due to their design and function. Screw compressors consist of driving and driven rotors, rotating toward each other. Compressed air or gas is by means of rotating to different sides of the rotors. Their rotation provides a central rotor in the form of a screw. Each element has a certain degree of pressure increase. This value depends on the length, pitch and shape of a pint of the outlet. Unique property of screw compressors is that they lack mechanical strength, causing imbalances. This allows the screw compressor to operate at very high speeds of rotation of the shaft, which provides high performance at small sizes. Initially, the compressor of this type used symmetrical screw. Today, the screw has acquired a variety of asymmetric helical (spiral) structures, which significantly increase the efficiency of compressors of this type. Screw compressors subdivided into several types: screw compressors, single screw, screw compressors in a double screw. Depending on the type of transmission is divided: screw compressors with direct drive, screw compressors belt drive. Screw compressors are most effective for large and medium-pressure conditions. An example of the modern screw compressors can be used compressors Remeza , providing high performance and characterized by high reliability in operation.
