Abstract

A liquid ring machine comprising a housing with discharge and suction windows, a fluid supply channel, an impeller located in the end cap, cantileverly mounted on a shaft supported by bearings mounted in the housing, a thrust bearing with a cap, characterized in that the fluid is supplied into the chamber between the radial bearings having channels for the passage of the working fluid, and the chamber communicates with an additional channel with the thrust bearing cavity.

Description

LIQUID S-RING-RING MACHINE The invention relates to compressor engineering and can be used in liquid-ring machines, which use 6 chemical, pulp and paper, mining, textile,

food, metallurgy and other industries and

Agriculture T H

A liquid ring machine containing a casing with discharge and exhaust windows, an eccentrically located impeller, a bidet filled with a hub with vanes and a cantilever mounted b casing, a hollow bobbin placed with a clearance of a hub, and having a channel for selection is selected. liquids, a release window on a cylindrical surface b of the area of the discharge window, and on the inner end face of the housing on the side opposite to the absorption window, a recess is located located b radially Between the billet and the outer edge of the emptying window with the possibility of communication between the inner cavity of the hub and the working chamber, and in the circumferential, between the sections corresponding to the beginning and end of the emptying, the bobbin is filled with a variable outer radius, the smallest magnitude of which is located in the region of the emptying window (1) .

The disadvantage of a custom device. There is a need for high accuracy. manufacturing and assembly to ensure

the coordinated work of the hub and hub, because the impeller is mounted cantilever on a shaft having a support in the forehead, and the hub is additionally supported by a sleeve located in the housing

 of the present invention is a visit to the manufacturability and reliability of the machine, as well as simplification of the design. This goal is achieved due to the fact that 5 of the proposed design uses plain bearings, the lubrication of which is carried out by the working fluid, which, 6 failure turn, allows

to carry out an adjustment of the working fluid b the chamber between the radial

j bearings, whence, through channels b radial bearings, on

sealing the hob of the casing and the blades of the impeller, on the liquid ring and on the mirror of the thrust bearing. The proposed design allows you to place a broken thrust bearing, perceiving axial loads on the shaft, inevitably arising from the console installation of the wheel, which increases the reliability of the machine. The proposed design is simple and technological in manufacture and operation. Figure 1 shows a liquid ring machine, a longitudinal section. The liquid ring machine contains: a housing 1, with discharge and suction windows 2, a working fluid supply channel 3, an impeller with vanes 4 located in the end cap 5, cantilevered on a shaft 6, supported by radial bearings 8 of the thrust bearing 9, mounted in the housing 1, the chamber 10 between the radial bearings 7 and 8, the passage of the working fluid 11 in the bearings 7 and 8, the radial grooves 12 of the thrust bearing 9, the cover 13 of the thrust bearing 9, an additional channel 14 for returning the working fluid from the cavity of the thrust bearing 9 to the chamber 10.

The device operates as follows.

The shaft 6 of the liquid ring machine receives rotation from engine M.

- 3 nalam 11 b bearings 7, lubricating them, gets on the seal

the lobbins of the housing 1 and / yupatok wheels 4, and then the liquid zone

rings. The remaining part of the working fluid through the channels 11 b of the radial bearings 8 gets into the cavity of the thrust bearing 9, then through the radial grooves 12 of the thrust bearing 9 and the additional channel 14

chamber 10 turns around. Here it mixes with the incoming working fluid, and the cycle breaks. Cyclic flow

working fluid from the chamber 10 through the cavity of the thrust bearing 9, the additional channel 14 b of the chamber 10 turns out to be possible due to the fact that the thrust bearing 9 works as a centrifugal pump, and the cross section of the channel 11 b of the radial bearings 8, additional channel 14, the size and shape of the thrust bearing 9, calculated in a certain way.

Particular loads booming on ball 6 are received by radial bearings 7 and 8 and thrust bearing 9. The machine operates in the usual manner.

The proposed design is simple and technologically advanced for manufacturing, and also reliable in operation.
