The proposal relates to pumping devices used mainly in mining machines, such as self-propelled drilling rigs that require remote control of the variable capacity pump from the cabin.

Known pumping unit comprising a pump adjustable performance with camera control and actuator, valve, drain tank, battery, pump swap the battery with the actuator and the pump swap the battery is communicated through the valve with battery [1].

However, in this from the changes in pressure in the pressure supply, that does not ensure stable operation of the pump.

The technical result, to achieve the aims of this technical solution is that it will allow to change the setting of the regulator directly in the process.

This result is achieved due to the fact that the pump device including a pump adjustable performance with camera control and actuator, valve, drain tank, battery, pump swap the battery with the actuator, and in which the pump swap the battery is communicated through the valve with battery, last communicated with the control chamber of the variable capacity pump and through the second valve to the drain tank.

The drawing shows a pump device. It includes pump 1 variable performance control chamber 2 and the actuator 3, the valves 4, 5, the drain tank 6, a battery 7, a pump 8 swap the battery with the actuator 9, and the pump swap the battery is communicated through the valve 4 with the battery 7 via the pressure line 10 camera control 2 control pump 1.

The device operates as follows.

When the solenoid valve 11 nadla is strali 10 in the battery 7 and the camera control 2. As a result, in the latter increases the pressure. When disconnecting the electromagnetic valve 11 nadupana cavity 12 valve 4 is connected with a pressure line 10 and the valve 4 is closed, while maintaining existing stable pressure. With the change of pressure in the accumulator 7 and the camera unit 2 changes the performance of the regulated pump 1.

For lowering the pressure in the accumulator 7 and the camera unit 2 includes an electromagnetic valve 13, and nadupana cavity 14 of the valve 5 is connected to the drain 6. The valve 5 is opened, fluid from the accumulator 7 and the camera control 2 merges and the pressure decreases. When off, the electromagnet 13 nadupana cavity 14 of the valve 5 is connected with a pressure line 10 and the valve 5 is closed. Remote enabling and disabling of the electromagnets 11 and 13 change the setting of the desired pressure in the accumulator 7 and the camera control 2 directly in the process, and therefore provide the possibility of stable control performance of the regulated pump 1 for the necessary parameters actuators.

Thus, the proposed technical solution will change the industry stable control performance of the regulated pump to obtain the necessary parameters actuators.
