(54) ПОРШНЕВОЙ КОМПРЕССОР(54) PISTON COMPRESSOR

II

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

Наиболее близким к изобретению по технической сущности вл етс поршневой компрессор , содержащий цилиндр с всасывающими и нагнетательными окнами, установленный в цилиндре с образованием рабочей полости поршень и смесительную камеру, сообщенную каналами соответственно с рабочей полостью и источником смазочно-охлаждающей жидкости 1.Closest to the invention to the technical essence is a piston compressor comprising a cylinder with suction and discharge ports, installed in the cylinder with the formation of a working cavity, a piston and a mixing chamber connected by channels with a working cavity and a source of coolant 1, respectively.

Недостатком известного поршневого компрессора вл етс невысока эффективность охлаждени сжимаемого газа.A disadvantage of the known reciprocating compressor is the low cooling efficiency of the compressible gas.

Цель изобретени - повышение эффективности охлаждени сжимаемого газа.The purpose of the invention is to increase the cooling efficiency of the compressible gas.

Указанна цель достигаетс тем, что смесительна камера выполнена в виде кольцевой проточки в стенке цилиндра, при этом каналы, сообщающие ее с рабочей полостью , выполнены заодно со всасывающими окнами, а каналы, которыми смесительна камера подключена к источнику смазочно-охлаждающей жидкости, сообщены с окнами и выполнены напротив последних.This goal is achieved by the fact that the mixing chamber is made in the form of an annular groove in the cylinder wall, while the channels that connect it to the working cavity are integral with the suction ports, and the channels by which the mixing chamber is connected to the source of coolant are communicated with the windows and performed opposite the latter.

При этом всасывающие окна выполнены в виде конических отверстий, сход щихс в направлении оси цилиндра.In this case, the suction ports are made in the form of conical holes converging in the direction of the cylinder axis.

На фиг. 1 схематично изображено порщневый компрессор, продольный разрез; на фиг. 2 - узел I на фиг. 1.FIG. 1 schematically shows a piston compressor, longitudinal section; in fig. 2 — node I in FIG. one.

Компрессор содержит цилиндр 1 с всасывающими 2 и нагнетательными 3 окнами, установленный в цилиндре 1 с образованием рабочей полости 4 поршень 5 и смесительную камеру 6, сообщенную каналами 7 и 8 The compressor contains a cylinder 1 with suction 2 and injection 3 windows, mounted in cylinder 1 with the formation of the working cavity 4, the piston 5 and the mixing chamber 6, communicated by channels 7 and 8

JQ соответственно с рабочей полостью 4 и источником 9 смазочно-охлаждающей жидкости . Смесительна камера 6 выполнена в виде кольцевой проточки в стенке цилиндра 1, при этом каналы 7, сообщающие ее с рабочей полостью 4, выполнены заодно со всасывающими окнами 2.JQ, respectively, with a working cavity 4 and a source of 9 coolant. The mixing chamber 6 is made in the form of an annular groove in the wall of the cylinder 1, while the channels 7, which connect it with the working cavity 4, are integral with the suction ports 2.

Каналы 8, которыми смесительна камера 6 подключена к источнику 9 смазочноохлаждающей жидкости, сообщены с окнами 2 и выполнены напротив последних, а всасывающие окна 2 выполнены в виде конических отверстий, сход щихс в направлении оси цилиндра.The channels 8, with which the mixing chamber 6 is connected to the source 9 of the lubricant cooling fluid, communicate with the windows 2 and are opposite the latter, and the suction ports 2 are made in the form of conical holes converging in the direction of the axis of the cylinder.

Claims

The compressor works as follows. When the reciprocating movement of the piston 5 in the working cavity 4 of the cylinder 1 alternately suction occurs and the subsequent injection of gas to the consumer. At the same time, at the time of gas suction into the working cavity 4, the intake gas enters the mixing chamber 6, where it mixes with the coolant flowing through the channels 8. From the chamber 6, the gas-liquid mixture is sucked into the working cavity of the cylinder through the suction ports 2, made in the form of conical holes converging in the direction of the axis of the cylinder 1. Mixing is also carried out when liquid and gas move in the suction ports 2. The gas-liquid mixture entering the cylinder 1, provides on the course of compression effective lubrication of the walls of the cylinder 1 and the cooling of the injected gas. Thus, the application of the invention allows the coolant to be in the working cavity of the cylinder in the state of the smallest particles, which increases the heat exchange. the surface of the coolant fluid and accordingly increases the cooling efficiency of the compressible gas. Claim 1. Piston compressor comprising a cylinder with suction and discharge ports, installed in a cylinder with formation of a working cavity and a mixing chamber communicating with channels through the working cavity and a source of coolant, in order to increase cooling efficiency compressible gas, the mixing chamber is made in the form of an annular groove in the wall of the cylinder, while the channels that connect it with the working cavity, are made integral with the suction windows The channels, with which the mixing chamber is connected to the source of coolant, are in communication with the windows and opposite the latter.

2. A compressor according to claim 1, characterized in that the suction ports are made in the form of conical holes converging in the direction of the axis of the cylinder.
