Description

The utility model relates to general engineering, in particular to autonomous mobile energy sources, and can be used to drive various hydroficated equipment, providing two independent working lines.

Known hydraulic pumping stations containing a power plant, a pumping unit connected to it by a suction line of a hydraulic tank and a pressure line, hydraulic equipment including a fluid flow regulator and distributor (RF patent No. 2171915 F 04 23/00, 07.23.99 and RF patent No. 2207244 V 25 D 9 \ 00, 01/19/03 g)

The disadvantage of these devices is low efficiency, because they can be used only for equipment (tools) that operate from one working line (pressure-discharge), i.e. It has one permanently connected executive water system.

The closest set of essential features, taken as a prototype, is a hydraulic pump station with two independent working lines, containing a power unit, a pump unit in the form of a double-flow gear pump and a tank for the working fluid connected to it and a hydraulic panel with flow controllers, a filter, and output hydraulic line fittings and equipment supply hoses (ELASTEC company prospectus - USA power plant D-10, copy for 2 liters attached).

The design of such a hydraulic pumping station allows powering equipment with two constantly operating executive waterworks or simultaneously two consumers with one waterworks, since each working line has its own independent parameters for liquid flow and pressure.

For example, the length of all devices for collecting accidentally spilled oil products on the water surface requires one independent controlled flow to the hydraulic drive of the working body collecting the oil product, and a second stream

with its adjustable parameters to the hydraulic pump of the pumping system of the collected oil products.

The main disadvantages of this design are:

- the inability to summarize the flow of the working fluid of two lines and quickly disconnect the working lines in an emergency (depressurization of hydraulic hoses, jamming of the working body or executive waterworks), which narrows the scope of the stations, especially for equipment with one executive water system, but with a high flow rate of the working fluid, and its functionality;

- the layout of the hydraulic equipment and the location of the channels on the hydraulic panel determined the location of the outlet fittings, and, accordingly, the sleeves of the working lines on the "front side" of the station, which complicates access to the controls.

The task that the proposed technical solution solves is to increase the efficiency and expand the scope of the station due to the ability to summarize two independent working fluid flows into either of the two hydraulic lines, doubling the range of controlling the flow rate of the working fluid, as well as reducing the amount of lost working fluid during an emergency depressurization of the hydraulic line by quickly switching the flow of the working fluid to drain into the hydraulic tank, blocking the latter's access to the working hydraulic lines.

In addition, the layout of hydraulic equipment on the hydraulic panel and channel drilling in it can be performed with the orientation of the outlet fittings along with the sleeves down the station, providing free access to controls.

To solve this problem, in a hydraulic pump station containing a power plant, a pump unit in the form of a double-flow gear pump and a tank for the working fluid and a hydraulic panel with flow controllers, a filter, outlet fittings, and also sleeves for connecting to the equipment, the authors propose after the regulators the flow set the flow adder, which allows, depending on the position of the control knob, to sum the flows on any of two independent hydraulic lines and two hydraulic distributors, allowing Using the control knobs, quickly, in one motion, turn off any of the hydraulic lines.

Placement of hydraulic equipment (adder flow regulators, distributors, filter on the hydraulic panel, as well as the execution of channels in the latter, with the outlet of the fittings and hoses of the hydraulic lines down the station, without falling into the station control zone.

The proposed design of the utility model increases its efficiency, increases functionality, expanding the scope of the pump station, while ensuring reliability and ease of use.

When conducting a search in patent and scientific and technical literature, no technical solutions were found containing the proposed set of features, which allows us to conclude that the proposed technical solution meets the criterion of "novelty"

The industrial applicability of the utility model can be seen from the design description of the hydraulic pumping station.

The proposed utility model is illustrated by drawings:

Figure 1 - shows a hydraulic pumping station - side view

In Fig 2 - shows a hydraulic diagram of the station

The hydraulic pump station contains a frame 1 with wheels, on which the power plant 2 is installed complete with the fuel system and the engine control drives of the power plant. The suction line of the double-flow gear pump 3 is connected to the hydraulic tank 4, and the pressure line 5 to the hydraulic panel 6, on which the hydraulic equipment is located, including flow controllers 7, on-off valves 8, adder 9 filter 10 mounted on the combined return hydraulic line. The relative position of the hydraulic equipment and the connecting channels in the hydraulic panel 6 determine the output of the fittings 11, and accordingly the hoses 12 of the hydraulic line down the station.

The principle of operation of a hydraulic pumping station by the example of connecting it to equipment with two executive hydraulic units (oil collector) is shown in the hydraulic diagram of the station (figure 2).

The power unit 2 is started, the engine of which drives the dual-flow gear pump 3. The working fluid through the suction two-channel line from the hydraulic tank 4 enters the sections of the gear pump 3 and, under pressure, through the two-channel pressure pipe 5 enters the hydraulic panel 6, where it is isolated from each other

drilling, each of the independent lines passes through its flow control 7 and on-off valve 8.

The speed of each executive body of the equipment is regulated by the dial of the flow controllers 7, the pressure in the line depends on the resistance on the working body and is regulated by the speed of the crankshaft of the engine of the power plant 2.

Each two-position dispenser 8 can be powered to drain the working fluid into the hydraulic tank 4 (position "I") or to the working branch A, C (position "II"),

Where:

A - to the hydraulic motor of the oil recovery pump,

C - to the hydraulic motor of the drums of the oil collector.

The "I" position on the drain is used:

- when starting the station and warming up the engine of the power plant 2 and the working fluid, when working on only one line and emergency shutdown of the line in an emergency.

In position "II", the working fluid flows under pressure with the required flow rate into the pressure line sleeve to drive the working body of the equipment.

When working on two hydraulic lines, both independent flows of the working fluid pass through their channels of the adder 9, and in the case when it is necessary to power the equipment (tool) with one executive water system, requiring an increased flow rate of the working fluid, the flows are summed up to any of the hydraulic lines.

The working fluid after passing through the Executive nodes (node) of the equipment through a single drain line B is returned to the hydraulic tank 4.

Thus, the proposed utility model will increase the efficiency, supplement the station’s functionality, expand its field of application, reducing the consequences of emergency situations due to the speed when disconnecting unpressurized hydraulic lines, while ensuring reliable and convenient control of the station.
