Fluid is a working fluid, which is driven by a pump or driving a motor. Fluid may be either in a gaseous state, i.e. compressed or liquid, that is incompressible. Simultaneous existence of fluid in two States, that is, to provide a gas-liquid mixture.

From the previous prior art installation for the supply of fluid under pressure, containing a volume of hydraulic machines action, the reservoir with the working fluid, a source of compressed gas and the valves (A. C. the USSR 541049, F 15 1/02, 1976).

The drawback of the prior art is that the supply of fluid under pressure has limited use.

Closest to the claimed device to the technical essence is the supply of fluid under pressure,mainly explosive and nonflammable mixtures on the basis of nitrogen containing air compressor low pressure, is connected by its output to the input of membranes is Alenia, having a liquid inlet and a pump outlet in communication with the separator having a liquid outlet and a gas outlet, which is the output of the installation, the tank and the pump feed connected to an input of the latter. RF patent 2089750 C1, 10.09.1997.

The disadvantage of this device is the high temperature of the separated liquid is supplied to the input gas booster pump supplied by a pump recharge, which in General leads to lower efficiency gas booster pump.

The objective of the invention is to increase the efficiency of the gas booster pump and installations for supply of fluid under pressure, mainly explosive and nonflammable mixtures based on nitrogen as a whole.

In addition, the unit can be equipped with an additional line for supplying gas from an external source connected to the gas inlet gas booster pump.

And the external source may be in the form of a pressurized pipeline gas field.

The drawing shows a block diagram of an installation for supplying fluid under pressure, mainly explosive iparameter mixtures on the basis of nitrogen.

The supply of fluid under pressure, mainly explosive and nonflammable mixtures on the basis of nitrogen, contains air compressor 1 low pressure connected to the output of a 2 input 3 of the membrane device 4, output 5 which pneumological 6 is connected to the gas inlet 7 gas booster pump 8 having a liquid inlet 9 and the outlet 10 gas booster pump 8 communicates with the separator 11 having a liquid outlet 12 and a gas outlet 13, which is the output of the installation, the tank 14 and the feed pump 15, is connected by its input to the last 16, the heat exchanger 17, input 18 which getrighttogo input 9 gas booster pump 8, while the pump 15 recharge completed dosing and connected to the output 22 to the output 13 of the installation.

Using an air compressor 1 low pressure (0.8 to 2.5 MPa) air from the atmosphere is supplied to the input 3 of the membrane device 4, where the air is oxygen and removing it into the atmosphere. Next, the remaining mixture containing 85-95% nitrogen, from the output 5 of the membrane device 4 is supplied via the air supply 6 to the gas inlet 7 gas booster pump 8.

If you have an external source of compressed gas (natural gas, petroleum or other gas safe under the conditions of ignition of hydrocarbon environment) installation can pump the gas into an object of consumption, for example in the well or pipeline. Then from the source 2>/P>At the same time on the liquid inlet 9 gas booster pump 8 to the hydroline 21 output 20 of the heat exchanger 17 is supplied metered quantity of the cooled process fluid, which can be used butter, oil or water.

In the gas booster pump 8 a mixture containing nitrogen, or a gas from an external source is compressed to a discharge pressure using a cooled working fluid.

Due to the fact that the liquid is cooled, it contains less dissolved gas and, therefore, the bulk modulus of elasticity of such a liquid is higher and correspondingly higher rigidity hydromechanical gas booster pump 8 and its efficiency. Next, the resulting gas-liquid mixture from the output 10 of the gas booster pump 8 is supplied to the separator 11. In the separator 8 of the gas-liquid mixture is separated liquid, which is removed from separator 8 through the liquid outlet 12 and hydroline 19 is supplied to the input 18 of the heat exchanger 17 where it is cooled. The remaining fluid containing compressed to the required pressure gas from the separator 11 with a gas outlet 13 is supplied to the consumer.

At the same time at the output 13 of the consumer outlet 22 of the pump 15 recharge made dosing, may p mixed with gas foam manufacturing operations with its use.

Mechanical muscle // 2247875

FIELD: devices for transformation of intrinsic energy of an energy carrier into mechanic motion of technical objects.

SUBSTANCE: the invention presents a mechanic muscle intended for transformation of intrinsic energy of an energy carrier into mechanic motion of technical objects with variable inertial parameters. The mechanic muscle contains some connecting elements and a filled in with energy carrier elastic shell reinforced in transversal and longitudinal directions by flexible non-expandable filaments. At that reinforcement in the longitudinal direction is made with a step ensuring a transversal deformation of the shell without a loss of leakproofness and reinforcement of the shell in the transversal direction is made with a step selected from conditions of provision of maximum shortening of an shell at simultaneous decrease of its transversal size, consumption of the energy carrier and increased response speed. At that the longitudinal reinforcement of the elastic shell is made layer-by-layer. And the discharge-antifriction layer is made out of continuous mutually crossing filaments helically laid on the shell surface. At that a step of the helical laying of the filaments of a next layer is equal to the previous one. Direction of a helical laying of the filaments of the next layer is a counter-directional to a previous one. Filaments of the layers are not linked among themselves and from interlayer rhombic cells, which diagonals are commensurable with value of deformation of the shell in an axial and in diametrical directions under a rhombic cell. At that the filaments of the next layer are shifted concerning to the filaments of the previous layer having the same direction of a step of the helical laying. The filaments of each layer are fixed concerning to adapters of the muscle separately from the shell and the length of an axial projection of the filaments exceeds the length of the shell, the energy layer is made out of the longitudinally oriented filaments fixed in respect to the adapters of the muscle and separately from the shell. At that the adapters of the mechanic muscle contain two coaxial surfaces for a separate fixation of the shell and the reinforcing filaments. At that the surfaces are partitioned by a ring-type boss, the height of which concerning to a surface for fixation of the shell corresponds to the thickness of the elastic shell. The adapters themselves or their external surface are made out of an electrical insulating material and contain gauges to control the working medium pressure and mutual motion of the adapters. Besides a decorative protective layer may be made out of the continuous filaments helically laid on the surface of the muscle. At that a step of a helical laying of the filaments of the next layer is equal to the previous step and direction of the step of the helical laying of the filaments of the next layer is counter-directional to the previous one. The filaments of the layers are not connected to each other and form the inter-layer rhombic cells. At that the filaments of a next layer are shifted to the filaments of the previous layer having the same direction of the step of the helical laying. And the filaments of each layer are fixed concerning to the adapters of the muscle and separately from the shell. The technical result is increased reliability.

EFFECT: the invention ensures an increase of reliability of operation of the mechanical muscle.
