Description

The field of technology.

The technical solution relates to the field of mechanical engineering, in particular, to the field of compressor engineering, namely, to compressors without lubrication of cylinders and seals. The compressor station is intended for use in medical purposes and in food industry enterprises.

prior art.

A piston opposed compressor is known (Voroshilov I.V. Piston opposed double-row two-stage compressor without lubrication of cylinders and seals - utility model patent RU 129166 dated 12/18/2012, publ. 06/20/2013, Bull. No. 17, [1]), containing a frame opposed base, to which cylinders are connected through remote lights, and oil deflectors are made on piston rods in the area of remote lights, while oil skimmers are installed between the frame and remote lights. The cylinders on the side of the remote lights are equipped with seals.

The disadvantage of this analogue is the significant size of the remote lamp, due to the need to provide space for the movement of the oil deflector. This leads to an increase in the external dimension of the compressor station and does not allow it to fit into the transport dimension (or into a sea container).

The design of the remote lamp used in analog [1] is disclosed in the patent of Voroshilov I.V. Reciprocating compressor remote lamp - utility model patent RU 134250 dated 11/26/2012, publ. 11/10/2013 Bull. No. 31, [2].

The design of the cylinders is known from the patents Voroshilov I.V., Storozhik S.O. DOUBLE-ACTION CYLINDER (VERSIONS) - patent for invention RU 2573724 dated 01/30/2014, publ. 27.01.2016 Bull. No. 3, [3]; Voroshilov I.V., Storozhik S.O. DOUBLE ACTION CYLINDER - patent for invention RU 2573730 dated 01/30/2014, publ. 27.01.2016 Bull. No. 3, [4]; Voroshilov I.V., Storozhik S.O. DOUBLE ACTING CYLINDER - utility model patent RU 170620 dated 09/30/2015, publ. 02.05.2017 Bull. No. 13, [5]. Disclosure of the proposed technical solution.

The technical problem to be solved by the claimed technical solution is to ensure the possibility of placing the compressor station completely within the transport clearance and sea container.

The technical result provided by the claimed technical solution is to reduce the overall dimensions of the compressor station.

The essence of the claimed technical solution is that the compressor station on the opposite base contains a frame of the opposite base, to which cylinders are connected through single-chamber remote lights. Oil deflectors are made on the piston rods in the area of the distance lamps. Oil skimmers are installed between the frame and the remote lights, having a thickness less than the wall thickness of the remote lights in the area of their installation. The oil skimmers are installed closer to the outer surface of the spacer lights to form space in the spacer chamber for the movement of the oil deflectors outside the plane of the inner wall of the spacer lights. The seals of the cylinders have an annular groove on the side of the distance lamps, made with the possibility of entering the oil deflector into it when the piston rod moves.

The above entity is a set of essential features of the claimed technical solution, ensuring the achievement of the claimed technical result.

Ensuring that the oil deflector enters when it moves in the spacer in the areas that were previously occupied by the cylinder seal and the oil skimmer made it possible to reduce the size of the spacer and also use a single-chamber light. This reduces the size of the compressor station along the axis of the cylinder, allowing the compressor station to fit within the shipping clearance or sea container, simplifying its transportation.

The enterprise-applicant of the technical solution produced samples of this solution, the tests of which confirmed the achievement of the technical result.

Brief description of the drawings.

Figure 1 shows an example of a four-row compressor in a compressor station, FIG. 2 - area of the remote lamp of the compressor station. Options for the implementation of the technical solution.

The compressor of the air compressor station is made on an opposed base, for example, on a four-row base 4M 2.5. The compressor is mounted on a single welded frame together with an electric motor from which the drive is carried out. All air lines, water lines, purge lines and oil line with pre-lubrication system are also mounted on the base frame and the refrigerator frame. Thus, the station is delivered as a single finished product in full factory readiness, with the exception of the automation cabinet that performs the function of control and emergency protection of the compressor, which is installed separately in the operator's room, or in another place where personnel can control the operation of the compressor without noise from the operating station.

The compressor has cylinders (1). In FIG. 1 shows 4 cylinders: the 1st and 2nd stage cylinders are double-acting, and the 3rd and 4th stage cylinders are single-acting with a working cavity on the side of the crankshaft.

In the compressor, air is compressed without lubrication of the cylinders and glands. To do this, instead of cast iron rings, piston rings made of composite non-metallic materials based on fluoroplast - 4 are used. Cooling of cylinders and gas in interstage and aftercoolers is carried out by running water.

The cylinders (1) are connected to the frame (2) through single-chamber spacers (3) - box-shaped cast-iron cases / spacers, inside which oil skimmers (4) are installed (Fig. 2). Inside the oil scraper, there is an oil baffle (5) and a pair of oil scraper rings (6), which prevent the intensive application of oil on the piston rod (7) and its further penetration in the form of an oil film from the frame (2) into the compression cavity along the rod (7).

The compact design of seals (8) and oil skimmers (4), taking into account the piston stroke, allows placing an additional device in the cavity of even a single-chamber lantern on the rod, which prevents oil from entering the rod in the form of an oil film - an oil deflector (9). On other well-known compressors, similar devices are placed in the cavities of two-chamber lanterns with a large dimension along the axis of the rod.

The oil skimmers have a thickness less than the wall thickness of the distance lamps in the area of their installation and they are installed closer to the outer surface of the distance lamps with the formation of space (10) in the remote lamp chamber for the movement of the oil deflectors outside the plane of the inner wall of the distance lamps.

The seals of the cylinders have an annular groove (11) on the side of the distance lamps, made with the possibility of the oil deflector entering it when the piston rod moves.

The use of the aforementioned construct excludes the ingress of oil into the cylinder cavity and further into the compressed air of the consumer. Thus, the compressor station can be operated for medical purposes and in the food industry. The installation of single-chamber lanterns made it possible to manufacture the compressor in a transport dimension in width, which greatly facilitates the process of transporting the station to the installation site.

Work description.

When the compressor is running, the oil separator (9) dumps oil from the rod, brought from the frame (2). In this case, the self-lubricating material of the seals (8) of the rods, oil seals (6) and sealing elements of the pistons lubricates the rubbing surfaces, which makes it possible to operate the compressor without lubrication.

Industrial applicability.

The claimed technical solution is implemented using industrially produced devices and materials, can be manufactured at any machine-building enterprise and will be widely used in the compressor industry.
