The invention relates to pump engineering, in particular, to pumping installations with norso pumps designed to inject a liquid-vapor mixture.

The aim of the invention is to improve the quality of adjusting the composition of azo-fluid mixture and the reduction of abarites with non-simultaneous actuation of valves.

The drawing shows a diagram of a device for injecting a gas-liquid mixture.

At the same time, the nuns 30 and 31 at the same time carry out pumping cycles in their phase, in which the liquid or gas-liquid mixture is displaced through the injection valves 17 and 18 into the discharge manifold 2 from additional chambers 12 and 13.

When the plunger 29 is in the course of forcing, the plungers 30 and 3 each in their phase take in suction cycles, while the discharge in the additional 12, 13 and working 5 and 6 chambers does not occur, because the gas is under excess pressure from the source through the inlet valves 14 and 15 gas from the collector 16 enters the additional chambers 12 and 13, the liquid remaining in them enters the working chambers 5 and 6, while the pressure n, i; i, HHx is actually set to iaBHbi.M d; 1 Laziness gas.

LIKE 1kosti.

L, operation of the device in the mode of injection of mixtures with menilim gas content (}) ase close valve 19 or 20.

For example, when the valve 19 is closed, when the plunger 30 runs at vs-cbiBLiHiic in working 5 and an additional 12 chambers, a discharge is created, which leads to opening of valves 27 and 8 and refilling of these chambers with liquid from a source. When vp1o, tpenii plunger 30 stroke injection fluid from the additional chamber 12 is forced through the discharge valve 17 into the discharge manifold 2. Thus, in this mode, only the liquid flows into the discharge manifold 2, from the chambers 13 and 12, and from the chamber 13 - gas-liquid mixture .

The volumetric flow of the hydraulically driven pump can be adjusted by moving the piston stroke limiter 28 22. The amount of gas entering the additional chambers 12 and 13 can also be regulated in principle by moving the valve gates 19 and 20 relative to the gas inlets of the valves 14 and 15, which allows It is possible to control the content of the gas phase in the pumped gas-liquid mixture over a wide range.
