(54) VOLUME ELECTROMAGNETIC PUMP (57) The invention improves the reliability of the pump. The shell b with the discharge valve 7 in the upper end is connected to an additional power source. The lower inner part of the shell 6 is hermetically connected to the outer upper part of the shell 1 so that the discharge valve 4 of the working chamber 5 is suction for the working chamber 8 formed by the shell 6. Power is supplied to the shells 1.6 alternately. 1 ill.

1645612 A2 mutual attraction of the turns of the electric coil 2 and the axial compression of the shell 1. In this case, the volume of the working chamber 5 is periodically changed, the pumped medium is sucked into it through the suction valve 3 and pumped through the pressure valve 4. Similarly, the axial compression of the additional shell 6 occurs, in which there is a periodic change in the working chamber 8, the suction of the pumped medium through the valve 4 and forcing through the valve 7. In this case, the power supply to the shells 1 and 6 is supplied alternately.

Depending on the need, the length of the pump can be increased by connecting new links.

The power supply is carried out in such a way that any adjacent chambers are alternately compressed, for example, so that in the first cycle the voltage is applied only to the odd links, causing them to be compressed, in the second cycle, all even ones are triggered. At the moment of reducing the even 25 links, the current medium is pumped into the odd working chambers not only due to the reduction in the volume of the first, but also due to the stretching of the elastic shells of the odd chambers by the compressed 30 neighboring ones, as a result of which rarefaction is created in the stretched chambers, which facilitates absorption. Then the odd links are reduced and the process repeats.

Claims (1)

35 claims Volumetric electromagnetic pump according to ed. St. No. 1341381, characterized in that, in order to increase reliability, the pump is equipped with at least one additional shell with a discharge valve in the upper end connected to an additional voltage source, identical to the main shell and covering it with its lower end. The invention relates to pump engineering, relates to electromagnetic pumps, can find application in various sectors of the economy for pumping fluids, in particular there. where 5 pumping systems are required with increased reliability, great compactness, and is an improvement on avt. No. 1341381. The purpose of the invention is to increase reliability. 10 The drawing shows a General view of a volume electromagnetic pump. The volume electromagnetic pump contains an elastic shell 1 reinforced with an electric coil 2 connected to a power source (not shown), and a suction and discharge valves 3 and 4 located at the ends of the shell 1 with the formation of the working chamber 5. Valves 3 and 4 are made, like the shell 1, from elastomer. 20 Electric coil 2 is made in the form of a multi-coil spiral spring placed in the shell 1 with the possibility of axial compression. The pump is also equipped with at least one identical shell 1 additional shell 6 with a discharge valve 7 in the upper end connected to an additional power source. The lower inner part of the additional shell 6 is hermetically connected to the outer upper part of the shell 1 so that the discharge valve 4 of the working chamber 5 is suction for the working chamber 8 formed by the additional shell 6, Volume electromagnetic pump operates as follows. When an alternating voltage is applied from the power source to the electric coil 2, an alternating electric current flows in the latter, leading to the formation of an electromagnetic field. The electromagnetic fields of the turns of the electric spiral 2 interact with each other, causing periodic
