Description

The invention relates to pump engineering, in particular, to the design of a pumping unit pumping highly viscous multicomponent mixtures, and can be used in designing hydrotransport systems for general industrial purposes.

The aim of the invention is to reduce energy costs by reducing the viscosity of the pumped mixture in the injection pipeline.

The drawing schematically shows a pump installation.

The pumping station for pumping a highly viscous multicomponent mixture contains two working chambers I and 2, equipped with sensors 3 and 4 levels, connected to control unit 5 connected to flow switches 6 and 7 of the working agent, supply and discharge piping 8 and 9, having check valves 10–13, connected respectively to the source of the pumped mixture and the consumer, centrifugal flow 14, connected to the working chambers 1 and 2 via pipelines 15 and 16 to flow switches 6 and 7. In addition, the installation additionally contains a line 17 connecting the centrifugal pump 14 with the discharge pipe 9, the sensor 18 of the properties of the pumped mixture mounted on the discharge pipe M. 9, the control unit 19 for controlling the flow of working a1ent to the discharge pipeline 9 with the cut-off 20, the flow rate ) 21 and the feed regulator 22 of the operating ai eHTa, with the feed regulator 22, the flow meter 21 n cutoff 20 placed on the line 17 connecting the centrifugal pump 14 with the discharge pipe 9.

Pump installation works as follows.

At O11, the position of the switching points 6 and 7 of the gyootok, the working agent from the working chamber 1 flows through the flow switch 6 to the inlet of the centrifugal pump 14. Under the action of the pressure differential, the gas-liquid mixture from the supply pipe 8 through the check valve II flows into the release The working chamber 1. Le splitting of the mixture occurs, for example, the evolution of gas and the separation of water from oil (around the working agent is added to each cycle the mixture enters the chamber). From the outlet of the centrifugal pump 14, the working agent through the pipe 16, the flow switch 7 enters the working chamber 2, displacing the gas-liquid mixture through the check valve 12 into the discharge pipe (.) G 9. At the time of passage of the oil or water-oil emulsion like water in oil (in (n) through the sensor 18 of the properties of the unmixed my mixture, its signal is converted in the control unit 19 into a command signal to open the flow cutter 20, and the operating agent (flowing water) from the centrifugal pump 14 but line 17 through

the feed controller 22 and the flow meter 21 enter the discharge pipe 9, providing hydrotransport of highly viscous products. The flow meter 21 and the feed controller 22 allow the supply of the required amount of water. At the end of the passage of the oil and water-oil emulsion, a signal is given through the sensor 18 of the flow medium properties, which is converted in control unit 19 to a close command signal.

The process of transferring the working agent (passing water) from the working chamber I to the working chamber 2 continues until those noji, while the boundary of the 11th section is the working agent and the fluid and liquid
