The invention relates to compressor and pump engineering, primarily to structures of liquid ring machines having devices for controlling production.

A known liquid ring machine with an adjustable capacity, comprising a body made of two halves, movably connected in place of the diametral connector 1.

However, in this machine, in the adjustment mode, the degree of internal compression is reduced, determined by the ratio of the volumes of the working cells in the suction and at the time of the end of the compression. As a result, at a constant final pressure, the external work of compression and the specific power consumption increase, and the labor intensity of manufacturing the machine body also increases significantly.

Also known is a liquid ring machine with adjustable capacity, comprising a housing with end clamps, one of which has a suction and discharge cavity, an impeller eccentrically housed in the housing with blades forming working cells, and a device for controlling productivity 2.

However, in this machine, the performance control is carried out in a narrow range, and there is also a hydraulic resistance in the liquid ring due to the regulating spacer, which leads to a decrease in reliability and an increase in the power consumption of the machine.

The purpose of the invention is to reduce power consumption and increase machine reliability.

The goal is achieved by the fact that in a liquid ring machine, comprising a body with end caps, one of which is made up of suction and discharge beds, an impeller eccentrically housed in the body with blades forming working cells, and a device for controlling performance, the latter is made view of a cylinder placed in the other end cap mounted in its cavity by a spring-loaded piston, equipped with an adjusting screw, and a system of channels connected in series to the working them to the cells on the side of the injection cavity and communicated with the cylinder.

FIG. 1 shows a liquid ring machine, a longitudinal section; in fig. 2 shows section A-A in FIG. one.

The liquid ring machine includes a housing 1 with end caps 2 and 3, the first of which includes suction and discharge cavities 4 and 5, an impeller 6 with blades 7 forming the working cells 8 eccentrically located in the housing 1, and a device for controlling the capacity made in the form of a cylinder 9 placed in an end cap 3 installed in its cavity 10 a spring-loaded piston 11 equipped with an adjusting screw with a screw 12 and a system of channels 13-16 connected in series to the working cells 8 on the pressure side and communicated with the cylinder 9. The liquid ring machine body 1 is filled with water, when the machine obrazuyuphey liquid

ring.

Liquid ring machine operates as follows.

When the liquid ring rotates in the suction cavity 4, the liquid moves away from the impeller 6, forming free space in the working cells into which the gas is sucked. In the injection cavity 5, the fluid enters the compressive cells while the gas.

When reducing the consumption of compressed gas, the piston 11 with the help of the adjusting screw 12 moves downward until the channels 3 and 4 are connected through the cavity 10 of the cylinder 9. As a result of the connection of the channels 13 and 14, the pressure increases

in the working cells 8 of the wheel 6 does not occur, due to the fact that part of the gas flows through the channels 13 and 14 into the suction cavity 4. The flow of the machine decreases by the amount of gas flowing from the cell on the compression side of the intake gas. With a further decrease in the consumption of compressed gas and an increase in pressure in the injection cavity 5, the piston 11 moves downward until the channel 16 is connected to the channel 13, and the consumption of the compressed gas is completely stopped. Thus, the proposed device allows smoothly adjusting performance over a wide range, reducing power consumption and power.

friction in the regulation mode, which leads to an increase in the reliability of the machine.
