( ПОРШНЕВОЙ ВЕРТИКАЛЬНЫЙ КОМПРЕССОР(PISTON VERTICAL COMPRESSOR

II

Изобретение относитс к компрессоростроению и касаетс поршневых вертикальных компрессоров.This invention relates to a compressor industry and relates to reciprocating vertical compressors.

Наиболее близким по технической сущности к предлагаемому вл етс поршневой Вертикальный компрессор с бесконтактным уплотнением поршн , содержащий цилиндр и установленный в нем с образованием полости сжати поршень, имеющий шток с подключенным к источнику жидкости осевым каналом и сообщенную с ним внутреннюю полость, частично заполненную жидкостью с образованием газовой и гидравлической полостей, перва из которых подключена при помощи вы-. полненного в дни1це поршн отверсти к полости сжати The closest in technical essence to the present invention is a piston Vertical compressor with a non-contact piston seal containing a cylinder and a piston installed therein to form a compression cavity, having a rod with an axial channel connected to the fluid source and an internal cavity communicated with it, partially filled with a fluid gas and hydraulic cavities, the first of which is connected by means of vy-. filled in the bottom of the piston bore to the compression cavity

Однако этот поршневой компрессор, обладает недостаточно высоким КПД.However, this piston compressor does not have high enough efficiency.

Цель изобретени - повышение КПД поршневого компрессора.The purpose of the invention is to increase the efficiency of a piston compressor.

Указанна цель достигаетс тем, что отверстие в днище поршн имеетThis goal is achieved by the fact that the hole in the bottom of the piston has

плавно сопр женные между собой сужающийс и расшир ющийс участки, а в днище и стенке поршн выполнены каналы, подключенные к гидравлической полости и зоне сопр жени участков отверсти .tapering and expanding sections are smoothly mated with each other, and in the bottom and wall of the piston channels are connected that are connected to the hydraulic cavity and the junction of hole sections.

На чертеже изобрак ена схема предлагаемого поршневого компрессора, продольный разрез.The drawing shows a diagram of the proposed piston compressor, a longitudinal section.

Поршневой компрессор с бесконтакт10 ным уплотнением поршн содержит цилиндр 1 и установленный в цилиндре с образованием полости 2 сжати поршень 3, имеющий шток k с подключенным к источнику жидкости осевым A piston compressor with a contactless 10 piston seal contains a cylinder 1 and a piston 3 mounted in the cylinder with the formation of a cavity 2 of compression, having a rod k with an axially connected to the source of fluid

15 channel 5 and an internal cavity 6 communicated with it, partially filled with liquid to form gas and hydraulic cavities 7 and 8, the first of which is connected with a piston 3 made in the bottom 9 of the piston 3 holes 10 to the cavity 2 of compression i the bottom 9 of the piston 3 has smoothly conjugated and expanding 11 and 12, and in the bottom 9 and in the wall 13 of the piston 3 the channels 1 are connected to the hydraulic cavity 8 and the interface of the portions of the hole 10. In the wall 13 of the piston 3 there are choke holes 15. Offered piston vertical compress) e; with contactless piston seal works as follows. During the upward stroke of the piston 3, the process of compressing gas in the cavity 2 is compressed and supplied to the consumer. A portion of the compressible gas from the compression cavity 2 enters the gas cavity 7 of the piston 3 passage. through the opening 10. Due to the presence of a narrowing and expanding sections 11 and 12, the flow of intake gas provides for the spraying of the fluid flowing through the channels 1 from the hydraulic cavity 8. The sprayed liquid at the same time cools the flow of gas sucked into the gas cavity 7, which is then The piston 3 is centered and sealed against cylinder 1. As piston 3 moves downward, gas is sucked into cavity 2 of cylinder 1 o With this pressure in cavity 2, compression decreases and is compressed The gas in the gas cavity 7 expires into the cavity 2 by squeezing through the opening 10, which, due to the presence of the constricting and expanding portions 11 and 12, provides the coolant from the hydraulic cavity 8 and sprays into the gas stream. Part of the gas in the gas cavity 7 provides, through the throttle holes 15, centering and sealing the PISTON 3 relative to the cylinder. As the fluid flows, the hydraulic cavity 8 is fed through the channel 5 from the source of coolant. Thus, making holes in the bottom of the piston with gently mating tapering and expanding "1c sections, and in the bottom and the wall of the piston channels connected to the hydraulic cavity and the junction area of the orifice sections, ensures" 1BayTe cooling of the compressed gas and thereby increases the efficiency compressor with contactless piston seal. Claims: Piston-type vertical compressor with non-contact piston seal, comprising a cylinder and a piston installed therein to form a compression cavity, having a rod with an axial channel connected to the fluid source and an internal cavity connected to it, partially filled with liquid, forming a gas and hydraulic cavities, first of which are connected by means of a compression hole made in the bottom of the piston to the compression cavity, in which, in order to increase efficiency by improving cooling, we compress bgo gas, the hole in the bottom of the piston has smoothly mating constricting and expanding parts, and in the bottom and wall of the piston there are channels connected to the hydraulic volume and the mating of the portions of the bore.
