DESCRIPTION OF THE INVENTION
The invention relates to the field of mechanical engineering and can be used in compressors, pneumatic and steam engines, in combined gas-steam engines, centrifugal pumps.
A centrifugal hydropneumatic machine is known, comprising a hermetic housing with outlets, an inlet pipe and two cut-offs, the housing is partially filled with liquid and there is a rotatably mounted impeller in the form of a rotor with radial curvilinear channels, And the outlets are made from the side of the wheel axis, and along the periphery of the rotor, the cutters are made with a calibrated gap to the impeller (DE 952445 A, 25.10.1956, F 01 C 7/00) .
The disadvantage of this design is an increase in the specific power of centrifugal machines and the expansion of the scope of application.
The object of the invention is to increase the specific power of centrifugal machines and expand the scope of application.
This object is achieved by the fact that a centrifugal hydropneumatic machine comprising a sealed housing with an outlet, an inlet pipe and two shut-offs, the housing partially filled with a liquid and a rotatably mounted impeller in the form of a rotor with radial curvilinear channels, Are provided on the side of the wheel axis, and the outlet holes are formed along the periphery of the rotor installed with the calibrated gap to the two cut-offs formed in the housing body according to the invention, the machine is provided with a distributor installed in the housing from the central part of the impeller, And outlet openings of the rotor channels, the cut-offs and the distributor are made in one another against the upper and lower cavities, the latter of which is made in the form of a cochlea and in the enlarged part is communicated by means of a pipeline and a distributor with the inlet holes of the rotor channels located in the upper cavity of the housing, This outlet is formed in the upper part of the upper cavity, and the intake manifold is communicating with the inlet holes of the rotor in the lower cavity of the housing by means of a distributor.
In addition, the upper cavity of the body can be made in the form of a cochlea.
In addition, the blades of the impeller can be thickened at the ends.
In addition, in the upper part of the upper cavity of the body, removable bumpers can be made.
The drawings show:
 1 - centrifugal hydropneumatic machine in the form of a compressor, steam or air motor, side view, section |
 FIG. 2 shows a centrifugal hydropneumatic machine in the form of a pump or a hydraulic motor |
The centrifugal hydropneumatic machine comprises a hermetic body 1, rotatably mounted therein, an impeller 2 in the form of a rotor with channels 3 with inlet openings 4 on the shaft side, cutters 5 separating the body into an upper cavity 6 and a lower cavity 7 made in the form of a cochlea with A hole 8 and a discharge conduit 9 connected via the distributor 10 to the inlet openings 4 of the impeller 2 in the upper cavity 6 where the liquid strikers 11 and the outlet 12 are installed, the inlet conduit 13 exiting the distributor 10 in the lower cavity 7 of the housing 1.
The centrifugal hydropneumatic machine works as follows.
In the compressor plants (FIG. 1), when the wheel 2 rotates from any drive in the channel 3 of the wheel 2, centrifugal forces arise, pushing the liquid out of the channels, whereupon through the distributor, the air or gas flows through the inlet pipe 13. From the channels 3, the liquid enters the lower cavity 7, whence, due to its cochlear-shaped form, is injected through the opening 8 and the conduit 9 by means of the distributor 10 to the inlet ports 4 of the channels 3 of the wheel 2 located in the upper cavity 6 of the housing 1, where, due to centrifugal forces and pressure, Channels 3, displaces air therefrom, which is lifted away from the residual liquid by means of bumpers 11 and other devices and exits through outlet 12 to the consumer.
In the pneumatic and steam engines (FIG. 1), compressed air, gas or steam is supplied through the inlet line 13 to the inlet ports 4 of the channels 3 of the wheel 2, pushes the liquid out of them and, due to the flow of curvilinear channels and the reaction of the jet, causes the impeller to rotate 2. The liquid then flows into the lower cavity 7, from which it is forced through the opening 8 through the conduit 9 to the inlets 4 of the channels 3 located in the upper cavity 6 of the body 1, from which it displaces the air or gases in the air channels 3 to the deflectors 11 and the outlet 12 , Again causing the impeller to rotate.
In the pumps and hydraulic motors (FIG. 2), a liquid is introduced into the inlet line 13, which, passing through the curvilinear channels 3 of the wheel 2, enters the lower cavity 7, then the liquid again flows into the curvilinear channels 3 of the wheel 2 via the conduit 9 and the distributor 10, but Already in the upper cavity 6 of the body 1, and further to the outlet opening 12. The strikers in this case are removed. If the impeller 2 is connected to an external drive, the machine operates as a pump, pumping the liquid. If the intake manifold 13 is connected to a high pressure hydraulic pipe, the machine operates as a hydraulic motor.
In pneumatic machines, the blades may be thickened at the ends in order to reduce leakage from the lower cavity 7 to the upper cavity 6.
When several centrifugal hydropneumatic machines are connected in series, the device can become multistage to create a high operating pressure.
The use of this invention will increase the efficiency of using centrifugal machines at low and medium speeds of rotation of the impeller, increase the torque and specific power of centrifugal pneumatic and hydraulic motors, expand the scope of application of centrifugal machines, for example, in combined gas-steam plants, aerators, purification plants, dustproof devices , Centrifugal pumps.
