Description

 The invention relates to a device for lifting, relates to vibration pumps and can find application in various sectors of the economy, as well as in everyday life for lifting liquids from wells, wells and other bodies of water.

 Known vibration pumps with an electromagnetic vibration exciter containing a bipolar magnetic circuit with a winding and an armature spaced apart from it by the size of the working air gap, connected through the rod with an elastic suspension. / V.M.Usakovsky "Water supply in agriculture". -M. Agropromizdat, 1989 /.

 Known vibration pump containing a bipolar core with coils, an electromagnet anchor mounted on a rod and connected with a damping suspension and a working valve, a suction valve. The core and anchor are housed in the housing. The water outlet is located next to the water inlet openings. / Electric vibrating household pump "INCAR-1" 1746.00.00.000RE Operation manual. - Perm, 1993, 15 pp. The disadvantage of this pump is the difficulty of increasing its performance, since the dimensions of the suction and discharge valves, the volume of the working chamber is limited by the diameter of the pump / well diameter /. Another disadvantage of the known pumps is the low load of the magnetic circuit due to the operation of the electromagnet with relatively large air gaps, which are selected taking into account the magnetic force arising in the exciter. In this case, the constant component force is parasitic, and for its compensation the air gap increases. As a result, the known pumps have low magnetic circuit efficiency and low efficiency. In addition, when operating in the pump, significant mechanical vibrations occur that reduce the life of the pump or the entire water supply system.

 Closest to the proposed invention is a vibration pump comprising a housing, covers with suction valves, rods with operating valves, elastic suspensions mounted between the housing and covers, a magnetic circuit with windings and anchors connected through rods to operating valves / RF patent N 2011025, class . F 04 F 7/00, 04/15/97 /. The disadvantage of this pump is also the difficulty of increasing its performance, low load of the magnetic circuit, low efficiency of use of the magnetic circuit, as well as significant mechanical vibrations that reduce the life of the pump.

 The objective of the invention is to increase productivity, efficiency, pump life.

 The essence of the invention is illustrated in FIG. 1, 2, 3, 4, 5, 6.

 In FIG. 1 shows a General view of the proposed vibratory pump.

 In FIG. 2 shows a magnetic circuit with a magnetic jumper / shunt /.

In FIG. 3 and 4 are graphs of the variation of the magnetic flux in the yoke / φ _max / magnetic core and shunt (φ _w).
In FIG. Figure 5 shows the change in the magnetic flux in the air gap (φ _δ ) and the yoke of the magnetic circuit (dashed line is the change in magnetic flux before the shunt).

 In FIG. Figure 6 shows a graph of the change in electromagnetic force (F) (dashed line - change in electromagnetic force before the introduction of the shunt).

 The pump contains a four-pole magnetic circuit 1 with windings 2 and magnetic conductive jumpers (shunts) 3, mounted in the housing 4 of the pump. Using elastic suspensions 5, fixed between the body 4 and the covers 6 and rods 7 at a distance of the air gap, anchors are placed 8. The anchors 8 through the rods 7 are connected with damping suspensions 9 and operating valves 10. Suction valves 11 are installed in the covers 6, holes are installed 12 for suctioning water and a hole 13 for discharging water.

где φ_мак - максимальный поток в магнитопроводе;
φ_δ - поток в рабочем воздушном зазоре;
B_n - индукция насыщения материала перемычки.The four-pole magnetic circuit 1 is made of a four-pole H-shaped. Magnetically conductive jumpers 3 are located between two pairs of poles at the level of the latter from the side of the anchors 8. The cross-section of the magnetically conductive jumpers 3 is selected from the relation

where φ _poppy - the maximum flow in the yoke;
φ _δ is the flow in the working air gap;
B _n - induction of saturation of the jumper material.

 The vibration pump operates as follows.

 Under the action of a sinusoidal alternating current and the opposing force of the elastic 5 and damping 9 suspensions, the anchors 8 make reciprocal movements and change the volumes of the hydraulic chambers 14 formed by the suction 11 and working 10 valves and damping suspensions 9 together with the parts of the housing 4. As a result, the displaced water accelerates through the cavities of the housings 4 and then is thrown out through the hole 13. Since the vibration of the two parts of the pump occurs in opposite directions at the same time, the total vibration I pump is reduced and depends only on technological deviations in the dimensions of the parts of the two parts of the pump.

 In the vibration pump, it is possible to change the water supply or supply water to two consumers. For this winding 2 electromagnets are connected to two sources of electricity. If one winding 2 is disconnected from the power source, then half the pump is working, its performance is equal to half the nominal value.

 The introduction of a magnetic shunt changes the flux in the air gap of the electromagnet, creating pauses without flux when the current passes through the zero value and reducing the constant component of the electromagnetic force. In this case, the total clearance in the electromagnet of the pump is reduced while maintaining the same amplitude of oscillations and hydraulic parameters of the pump. The above leads to a decrease in the magnetizing component of the current and an increase in the efficiency of the pump.
