Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a high-efficiency reciprocating piston electro-

TECHNICAL FIELD [0001] The present invention relates to a high-efficiency reciprocating piston electromagnetic pump used for transferring a gas or a liquid (hereinafter referred to as "fluid"). Efficiency reciprocating piston electronic pump capable of freely controlling the reciprocating movement distance and the moving speed of the piston in the cylinder by power supply control that enables independent generation of a magnetic field by independently installing the number of the piston.

Generally, a transfer pump for transferring gas or liquid is to transfer the fluid at a predetermined position to a desired position by rotating the impeller using the rotational driving force of the motor. The transfer pump is generally connected to the crankshaft of the motor by a rotor The piston is reciprocated in the cylinder and the check valves at both ends are alternately opened and closed to transfer the fluid.

However, the conventional transfer pump has a problem of low energy efficiency due to the motor. Also, in the method using the piston and cylinder, there is a problem of noise generation in the process of converting the rotational motion of the motor into the linear reciprocating motion by the crank In addition, there is a problem that the structure becomes complicated and the manufacturing cost increases.

To improve this point, Japanese Unexamined Patent Publication No. 56-66467 of Patent Document 1 discloses that this prior art uses a commercial AC power source to repeat the attraction and repulsion of the permanent magnet by the electromagnet, (Electromagnetic) fluid pump in which suction and extrusion are repeated.

This fluid pump is advantageous in that it is not provided with a separate power motor but has a small size as well as an improvement in energy efficiency. However, since the fluid pump is provided at a position outside the stroke of the permanent magnet reciprocating while sucking and repelling the electromagnet, There is a problem in that the distance between the permanent magnets reciprocating in the cylinder and the electromagnets becomes relatively large because the electromagnets are arranged on the left and right sides.

Therefore, in order to obtain the starting torque necessary to change the direction of motion in such a state, a large amount of power is required to generate electromagnetic force inversely proportional to the square of the spaced distance in the electromagnet, which may cause a decrease in efficiency. Since the power available is very limited, the fluid pump has a small output, which is mainly used for toys and simple facilities, and is not economical to be used for industrial use.

To solve the problems of the prior art, Japanese Utility Model Registration No. 96-3409, which is disclosed in Patent Document 2, has been proposed. However, this prior art also discloses that the electromagnets of the fluid pump have four electromagnets 5A-5D, And has a structure in which a driving coil is wound around a core protruding along the longitudinal direction of the main body 1.

However, in the case of a small-size fluid pump, since the driving coils of the electromagnets, which can be divided into a plurality of small portions, are limited, the length of the driving coils and the amount of current flowing therethrough are relatively small The electromagnetic force of the electromagnet is also made small, so that the output of the fluid pump becomes small. In particular, there is a problem that it is difficult to control the reciprocating distance of the piston.

On the other hand, Patent Document 3 also proposes a piston fluid pump heating system. However, as disclosed in Patent Document 2, the heat medium is moved to a desired position while reciprocating the piston with respect to the coil portion installed over the entire length of the cylinder There is a problem that it is difficult to control the reciprocating movement distance of the piston, and it is difficult to control the strength of the fluid pump.

Therefore, it is urgently required to develop a high-efficiency reciprocating piston electronic pump capable of freely controlling the reciprocating movement distance of the piston in the piston electromagnetic pump, while increasing the reciprocating distance of the piston by a factor of two.

FIGS. 2A to 2I are diagrams showing steps of an operating state of the high-efficiency reciprocating piston electromagnetic pump shown in FIG. 1,

Hereinafter, a more preferred embodiment of a high-efficiency reciprocating piston pump according to the present invention will be described with reference to the accompanying drawings.

1 is a cross-sectional view showing an example of a high-efficiency reciprocating piston pump according to the present invention.

As shown in the drawings, the structure of the high-efficiency reciprocating piston electromagnetic pump 100 according to the present invention can be roughly divided into a cylinder 110, a piston 120, a plurality of independent first through third coils 131, 132, and 133, and a power control unit 140.

The cylinder 110 is formed in the shape of one straight pipe so that a fluid inlet 111 and a fluid outlet 112 are formed opposite to each other so that fluid can be introduced and discharged at both ends and the fluid inlet 111 and the fluid The valve 112 is provided with a check valve 113 to prevent the fluid from flowing through the cylinder 110. The fluid inlet 111 and the fluid outlet 112 are alternately opened or closed . Fluid piping (not shown) provided for various purposes may be installed in the fluid inlet 111 and the fluid outlet 112 in a watertight manner.

The piston 120 is accommodated in the cylinder 110 so as to reciprocate in a shape corresponding to a sectional shape of the cylinder 110. The piston 120 has an N pole and an S pole A through hole 121 is formed in the center of the piston 120 to allow the fluid to flow therethrough and a through hole 121 is formed at one side of the piston 120 to prevent reverse flow The opening and closing plate 123 is provided to open and close the piston 120 when the piston 120 reciprocates, thereby allowing the fluid to flow in and out. The length of the piston 120 is formed to have a length corresponding to the width of one of the first through third coils 131, 132, and 133. The reason is that the reciprocating distance of the piston 120 may be shifted to a distance corresponding to the entirety of the first to third coils 131, 132, and 133, but any one of the first to third coils 131, 132, Width or a distance corresponding to the width of two coils. Therefore, the length of the piston 120 can be arbitrarily changed in accordance with the variation of the width of any one of the first to third coils 131, 132, and 133.

The coil 130 is independently arranged around the cylinder 110 by a plurality of first to third coils 131, 132 and 133. The number of the coils 130 is larger than the number of the coils 130 The reciprocating distance of the piston 120 can be adjusted by adjusting the number of the piston 120 disposed in any direction. The present invention is characterized in that the coils 130 are independently arranged by the first to third coils 131, 132 and 133 so that the first to third coils 131, 132, and 133, respectively, An independent magnetic field is generated in which the S-pole and the N-pole or the N-pole and the S-pole are alternately performed in accordance with the alternate power application direction of the battery. Independent magnetic field generation in which the S pole and the N pole from the first to third coils 131, 132, and 133 are alternately performed is performed by moving the moving distance of the piston 120 in the cylinder 110 from the first to third It is possible to freely adjust the amount of fluid to be fed while giving a pressure to the coil 131, 132, 133, which is moved by the amount corresponding to the magnetic field generation region of the coil. The first to third coils 131, 132 and 133 are formed of a general magnetic body core and a coil installed in the magnetic body core.

The above operation can be performed according to the speed of switching the power application direction and the power application direction applied to the first to third coils 131, 132, and 133. This alternate power application is performed by the power control unit 140 . The power control unit 140 includes a power control circuit for alternately applying power to the first to third coils 131, 132 and 133 in a forward or reverse direction. The first to third coils 131, 132, Since various circuits can be employed for the power supply control circuit for this purpose, only one of them is specifically described in the present embodiment.

The power control unit 140 is installed in an electrical circuit with the first through third coils 131, 132, and 133. In accordance with the settings of the users, the power controller unit included in the power control unit 140 may include first to third Alternately applying forward or reverse power to any one, two or all of the coils 131, 132, and 133 so that the N-poles and the S-poles from the first to third coils 131, 132, and 133 are alternately Thereby causing the piston 120 to be reciprocated by a corresponding distance of the magnetic field generating region generated from the first to third coils 131, 132 and 133 in the cylinder 110. At this time, The fluid flowing through the fluid inlet 111 is continuously fed through the fluid outlet 112 to a desired destination while generating a pressure corresponding to the movement. Also, the power control unit 140 controls the piston 120 to rotate in the forward and reverse directions alternately (alternately or in reverse) to the first to third coils 131, 132, The poles and the S poles are controlled to reciprocate rapidly or slowly in a reciprocating manner while responding to the alternating magnetic field generation speed. The control of the reciprocating speed of the piston 120 by the power control unit 140 is advantageous in that the fluid can be quickly or reliably fed to a desired destination.

FIGS. 2A to 2I are diagrams showing the operating states of the high-efficiency reciprocating piston electromagnetic pump shown in FIG. An operation example of the high-efficiency reciprocating piston electromagnetic pump according to the present invention will be described with reference to the drawings.

2A to 2I illustrate a case where the power control unit 140 controls the piston 120 to move one by one corresponding to the first to third coils 131, 132 and 133 provided independently of the cylinder 110, This is an example of the operation process of pushing. First, a description will be given of how the piston 120 is operated stepwise in the positive direction by the power control by the power control unit 140 with reference to FIGS. 2A to 2E.

2A is a schematic diagram illustrating an operation of a reciprocating piston electromagnetic pump 100 according to the present invention when power is controlled from a power control unit 140 to a coil 130. The third coil 133 is turned off While the first and second coils 131 and 132 are controlled to apply a forward power to both ends of the first and second coils 131 and 132 so that a magnetic field having the same polarity as that of the permanent magnet of the piston 120 is generated. The reason why the control circuit is controlled in this manner is that the piston 120 is temporarily in a stable state so that the piston 120 is not moved to the first predetermined position, that is, the first coil 131 before the movement.

2B shows a state in which the power is turned off from the power control unit 140 to the first and third coils 131 and 133 while the second power is applied to the second coil 132, The polarity of the piston 120 in the opposite direction to that of the permanent magnet of the piston 120 is independently generated only at both ends of the first coil 132 and the second coil 132, And is quickly moved to the area of the second coil 132 while being attracted by the magnetic force. The movement of the piston 120 causes the oil pressure enough to move the piston 120 to be generated in the cylinder 110 so that the opening and closing valve plate 123 of the piston 120 itself remains closed, The opening and closing valve plates 113 of the cylinder 110 are opened in proportion to the oil pressure corresponding to the movement of the piston 120 so that the fluid is allowed to flow into the cylinder 110 through the inlet 111. The switching from Fig. 2A to Fig. 2B is performed quickly.

2C shows a state in which the first coil 131 is controlled to be in the OFF state from the power control unit 140 in the state of FIG. 2B while the second power and the third coils 132, So that a repulsive force magnetic field is generated by polarizing the same polarity as that of the permanent magnet of the piston 120 so that the piston 120 is maintained in a stable state so as not to be moved within the region of the second coil 132. The reason for this is the same as that in Fig. 2A.

In FIG. 2 (d), the first and third coils 131 and 132 are controlled to be turned off from the power control unit 140 while the third coil 133 is supplied with the reverse power again The piston 120 independently generates the polarity opposite to the polarity of the permanent magnet of the piston 120 only at both ends of the third coil 133 so that the piston 120 reacts strongly to the magnetic field of the third coil 132, (133).

The movement of the piston 120 to the region of the third coil 132 further opens the opening and closing valve plates 113 of the cylinder 110 more in proportion to the movement of the piston 120 than the state of FIG. The amount of fluid flowing into the cylinder 110 is increased.

In FIG. 2E, in the state of FIG. 2D, the first coil 131 from the power control unit 140 is controlled to be kept in the off state as it is while the second coil 131 and the third coil 132 So that the magnetic field having the repulsive force of the same polarity as that of the permanent magnet of the piston 120 is temporarily generated so that the piston 120 is temporarily stable so as not to be moved in the region of the second coil 132 State. The reason is the same as that in FIG. 2A.

Referring to FIGS. 2F to 2I, it is explained that the piston 120 is operated in a stepwise reverse direction by the power control by the power control unit 140. FIG.

In FIG. 2F, in the state of FIG. 2E, the first and third coils 131 and 133 are controlled to be kept in the off state from the power control unit 140 while the second coil 132 is again supplied with the reverse power So that the polarity of the opposite direction to the polarity of the permanent magnet of the piston 120 is independently generated only at both ends of the second coil 132 so that the piston 120 is able to generate a strong magnetic field in response to the magnetic field of the second coil 132 2 coils 132, as shown in FIG. The reverse movement of the piston 120 to the region of the second coil 132 causes the opening and closing valve plate 123 of the piston 120 to open only to the extent corresponding to the pressure of the reverse movement of the piston 120, So that the fluid introduced into the piston 120 through the through hole 121 of the piston 120 is allowed to flow into the cylinder space of the region opposite to the piston 120. [

In FIG. 2G, in the state of FIG. 2F, the third coil 133 from the power control unit 140 controls the power supply to be maintained in the off state as it is, while the first and second coils 131, The power is again applied so that a magnetic field having a repulsive force of the same polarity as that of the permanent magnet of the piston 120 is generated so that the piston 120 is temporarily held in a stable state so as not to be moved in the region of the second coil 132 . The reason is the same as that in FIG. 2A.

2H, in the state of FIG. 2G, the second and third coils 132 and 133 from the power source control unit 140 are controlled to be kept in the off state while the first coil 131 is again supplied with the reverse power So that the polarity of the opposite direction to the polarity of the permanent magnet of the piston 120 is independently generated only at both ends of the first coil 131 so that the piston 120 is able to respond to the magnetic field of the first coil 131 strongly 1 coil 131 to move it. The reverse movement of the piston 120 to the region of the first coil 131 is performed only when the opening and closing valve plate 123 of the piston 120 corresponds to the pressure of the reverse movement of the piston 120 The fluid that has been introduced into the space on the right side of the cylinder 110 as viewed in the drawing flows through the more open through hole 121 of the piston 120 into the space on the left side of the cylinder To allow for more inflow of.

In FIG. 2I, only the third coil 133 from the power control unit 140 controls the power supply to be maintained in the off state while the first and second coils 131 and 132 are in the forward direction The power is again applied to generate a magnetic field having a repulsive force of the same polarity as that of the permanent magnet of the piston 120 so that the piston 120 is temporarily kept in a stable state so as not to be moved in the region of the first coil 131 . The reason is the same as that in FIG. 2A.

The operation state of FIG. 2I is a return to the initial operation state of FIG. 2A. In this state, the power is again alternately applied in the forward and reverse directions by the power controller 140 so as to be operated in a state of being circulated from FIG. 2B to FIG. The fluid sucked into the cylinder 110 is pumped to the desired position through the fluid outlet 112 through the fluid opening / closing plate 113 which is opened by the amount corresponding to the moving pressure of the piston 120.

In order to facilitate understanding, in the above embodiment, power supply alternately applied to the coil 130 from the power supply control unit 140 has been described in terms of operation of the piston 120. However, Power application is alternately controlled so that the piston 120 is moved stepwise corresponding to each of the coils 131, 132, and 133 while feeding a desired amount of fluid.

Particularly, the movement of the piston 120 in the cylinder 110 can be freely performed in accordance with the control of the alternating power supply switching from the power supply control unit 140 to the coils 131, 132, and 133 in the forward or reverse direction . Accordingly, when it is necessary to speed up the feeding of the fluid, a control signal is inputted from the power control unit 140 so that the alternating power supply applied to the coils 131, 132, The control signal for the alternating power switching applied to the coils 131, 132, and 133 from the power control unit 140 in the forward or reverse direction may be delayed You will understand.

Also, in the above embodiment, the movement of the piston 120 in the cylinder 110 has been described as moving stepwise with respect to each of the coils 131, 132, and 133. However, The reciprocating motion of the piston 120 in the cylinder 110 is moved from the first coil 131 to the third coil 133 of the cylinder 110 at a time unlike the above embodiment The piston 120 may be returned to the first coil 131 from the third coil 133. The piston 120 may also be moved back and forth by the coils 131, 132, and 133 in the power supply control circuit, The N-pole and S-pole magnetic fields that cause the S-pole, N-pole magnetic field, and repulsive force, which induce attractive force for strongly attracting the piston 120, are alternately applied to the coils 131, 132, Foot To make the piston 120 is stronger than the pressure by the power-on control that can be controlled to be reciprocated, causing. It will be appreciated that such a control method may be implemented in various ways through the design of the power control circuit set in the power control unit 140.

[ The opening and closing plates 113 closing the fluid inlet 111a and the outlet 112a are opened and closed by the suction output generated in the cylinder 110a when the reciprocating operation of the piston 120a is performed by the applied power source, And the outlet port 112a, respectively. Other operations are the same as those of the above-described embodiment, and a detailed description thereof will be omitted.
