A mobile container pumping unit is designed to collect spilled oil, pump oil and oil products from oil pipelines and oil pipelines when they are freed up for repair, fill main oil pipelines with water, etc., has a lightweight design that allows transportation to the place of work

on the external suspension of the helicopter, in the back of a vehicle or drag. It is a complex of energy and pumping equipment located on a sled type chassis.

The research and development work carried out by NII TNN LLC and Transneft organizations made it possible to develop the basic requirements for a mobile container pumping unit, produce prototypes and conduct their tests. The results showed an increase in the range of the pump in supply from 50 m / h to 300 m / h, in pressure from 50 to 350 m. The pumping equipment of the installation allows you to pump both oil and light oil products. In addition, the new design provides transportation of the device to the place of work in the vehicle body, on the external suspension of the helicopter or drag.

The equipment of the proposed device is mounted in a container. The container consists of a frame made in conjunction with the chassis 1 and the hood 4.

A power plant, a pump, a shield of instrumentation are mounted on the frame, they are covered with a hood from the outside, and the chassis itself has runners and drawbar.

To protect the power plant 2 and pump 3 from atmospheric precipitation and external accidental shocks during transportation of the mobile container pumping unit, they are closed by a hood 4. The hood 4 is separated by a sealed partition separating the engine compartment from the explosive pump compartment. A sealed partition prevents the pumped explosive atmosphere from getting into hot engine parts in case of emergency release. The hood has doors for access to equipment.

The power plant 2 is made in conjunction with an internal combustion engine, a clutch, a multiplier and a prestarting heater, and is connected to the pump 3 by a cardan shaft 9. Control

 power plant 2 is carried out by the control panel of the power plant 6.

Pump 3 of a two-module design with piping and ball valves for switching modes. The piping of the pump with ball valves allows you to quickly switch the modules to serial or parallel operation, which provides an extended range of pump operation from 50 m / h to 300 m / h, pressure from 50 to 350 m. The pumping equipment of the installation allows you to pump both oil and light oil products. Pump 3 is equipped with a shield for instrumentation of pump 5. It is connected to the inlet sleeve by a knee to connect to the pump 11, and to the output sleeve through a knee to connect to the pump 11, a wedge gate valve 12, an ultrasonic flow meter 10, and a reversible rotary shutter 13.

To protect the mobile pumping unit from unacceptable operating modes, the alarm and protection system unit 7 was used, which turns off the internal combustion engine of the power plant 2 during unacceptable operating modes (low or high pressure at the pump inlet, high pressure at the pump outlet, exit from building mechanical seals, etc.).

To illuminate the site around the mobile container pumping unit, energy-saving 14 outdoor lights (4 pcs.) With an LED module were used. The headlights are connected via explosion-proof connectors.

The exhaust system of the internal combustion engine of the power plant is equipped with a removable spark arrestor 15. The exhaust pipes of the engine are closed by a casing that protects against the presence of explosive atmospheres on the hot parts of the pipeline.

A remote control is provided to improve the operator's working conditions.

It provides remote control of equipment of a mobile container pumping unit and control of pumping parameters. The design of the remote control provides the ability to remotely control and control the pumping parameters of a mobile container pump unit, for example, in a heated trailer or shelter. To ensure safety requirements, the room (trailer) should be located at a distance of 25-30 meters from the pump unit.

A mobile container pumping unit is provided with a fire extinguishing system: three fire extinguishers, for example, OP-8 with a volume of 8 liters and a foam generator, for example, GPS-200 with a foam solution supply pipeline.

Work of a mobile container pumping unit.

Transportation of the device to the place of work can be carried out in the back of a vehicle, on the external suspension of a helicopter, or by drag.

At the site of scheduled work or accident, produce its deployment. To do this, carry out preparatory work: connect the grounding device to the ground loop, check the quality of grounding, insulation of the power supply circuits, connect temporary pipelines to the input and output of the pump 3.

At the pump outlet, a wedge gate valve 12, an ultrasonic flowmeter 10, a rotary back-lock valve are mounted 13. Hydraulic tests of temporary pipelines are carried out, heating

engine, the inclusion of electrical equipment installation.

Then start the pump to the desired mode of operation by adjusting the speed of the power plant 2.

After work, the installation is minimized and prepared for transportation. For this, temporary pipelines are disconnected, product residues are drained from the pump, the electrical equipment is turned off, and the hood doors are closed.

The application of the proposed utility model increases the range of the pump in supply from 50 m ³ / hour to 300 m ³ / hour, in pressure from 50 to 350 m and provides pumping of both oil and light oil products.
