Definitions

• the essential invention is related to the complex, and, moreover, to the central flavor.
• the leading level of technology Known is a central compressor, in the corpus of the corpus, which is closed with one element and is located
• the statistic elements contain diaphrases, diffusers, and common - directing allarates, which are rigidly connected between themselves.
• ⁇ contains the shaft, which is installed in the lodpids, and the working forests.
• the diaphragm connectors use the same type of connector to keep them out of the box for ease of use.
• the design of split diaphragms is becoming more complicated, due to the presence of rail elements.
• the presence of a socket for replacement makes it hard and increases the possibility of mutual displacement of both diaphragms, which reduces the need for their production and assembly.

• the central piece of technology, developed in accordance with the invention, is comparatively developed in production and in the process of assembly, which is reliable in operation because of the increase in price, which is very good.
• the ⁇ ata ⁇ lse of the four ⁇ ig. ⁇ depicts the centrally necessary compound, in accordance with the language of the tongue, lord ⁇ lnom; ⁇ ig.2 - node ⁇ on ⁇ ig. ⁇ on a larger scale; ⁇ ig. ⁇ - node ⁇ on ⁇ ig. ⁇ on a larger scale.
• the described model considers a two-stage cytropressor, which contains a corpus I (fig. ⁇ ). Corpus I is designed as an integral cylindrical part 2 and a torso wall 3, made 5 as a whole. The corpus I closes with a shell 4 with the corpus I. The corpus 4 is connected to the corpus I by studs 5, which are located in the same space.
• Diaphragms '10, II, 12, 13 are cut out as monolithic (intact), that is, they do not have connectors.
• Diaphragm 10 was made in one piece with corpus 17, in which a corpus was installed 18.
• Diaphragms 10 and 13 for the existence of a breakdown of the package 6 of the old elements are tightly connected to the middle part of the 22-series with bolts, which are equally important. ⁇ m ⁇ m ⁇ all elements
• Diaphragm 10 is rigidly connected to the torso wall 3 corpus I by bolts 23, equally located on the corpus. As a kind, the whole package is 6 statuary
• ⁇ 7 contains a shaft 25, on ⁇ installations
• Working forest 26 has a unique connection with shaft 25, which provides a comparatively easy attachment and makes good harvesting of hardwood 26.
• Working wheels 26, 27 have driving disks 32, 33, respectively.
• ⁇ 7 is installed in the bearings 18, 20 of the total displacement, but it is kept by a comfortable bearing 21.
• the internal seals 38 and 39 of shaft 25 are made identical and installed in corpus 17 and 19,
• the labyrinth seals 38 and 39 have arms 45 (fig. 3) and tombstones 46, which have a cylindrical bearing 47 of the shaft 25, and form a small diaphragm seal 38 and 38 ⁇ réelle ⁇ ⁇ -

• the diaphragm 10 with the corpus 17 and the bearing 18 installed in it and the labyrinth seal 38 and the labyrinth seal 38 are used.
• the office of the compressor is analogous to the laptop - 8 - this type.
• the presence of monolithic diaphragms has made it possible to have a tough concept of the statistic elements of the pack. This ensures the consistency of the statistic elements of the 5th package and makes it possible to have the smallest gaps in the labyrinth seals, which increases the efficiency.
• the efficient operation of the labyrinth seals and the monolithic concept of diaphragms reduces the energy consumption for internal flows and increases the life expectancy of 10 prices.
• the multiplicity of differential diaphragms excludes the loss of oil in the whole part of the compressor from the hydraulic seals.
