Description

1233468 V. Description of the invention (1) 1. [Technical field to which the invention belongs] The present invention mainly relates to a piston pump, and more particularly to an electromagnetic rotary piston pump. 2. [Previous technology] A pneumatic pump is a device that uses mechanical principles to reduce gas volume to increase gas pressure. There are generally three types of reciprocating, centrifugal and axial flow. The reciprocating pump can obtain a wider pressure range , So it ’s most commonly used by people. Reciprocating pumps are mainly called reciprocating piston pumps because a piston reciprocates in a certain space to compress the gas to generate pressure. At present, in order to enable the reciprocating piston pump to obtain a large gas pressure, electromagnetic force is usually used to drive the piston, as shown in Figure 1. However, the reciprocating piston pump shown in FIG. 1 has the following problems. First, after the piston compresses and discharges the gas, the piston must return to the initial position to perform the next compression stroke, so the obtained gas pressure will have a problem of pressure discontinuity. Second, in order for the pump to obtain stable and continuous pressure, an additional pressure storage tank is usually required. Third, the intake valve, exhaust valve, and check valve that limit the direction of gas in and out of the double piston pump are composed of many parts, which not only increases the complexity of the system, but also makes it difficult to maintain the system. Fourth, the friction generated during the reciprocating movement of the piston will consume a large amount of kinetic energy of the piston, which must provide more kinetic energy to the piston, resulting in an increase in work costs and a decrease in work efficiency. In view of this, the present invention proposes an electromagnetic rotary piston pump to

The air-tight β space 1 11 is in communication with the air inlet opening 21 arranged near the annular partition plate 1 3a.

The pistons 14a to 14e can be accelerated in stages as they pass through the solenoids 15a to 15e one by one. The wind & tail magnetic field, for example, immediately after the piston 4b is accelerated, the vacuum effect produced by the inner ring will pass through the hole 121 in the gas-tight ring tube 12 in the air-tight space 11 1 of the outer ring tube 1 1 Inhalation of the inner ring tube = Asia and the next accelerated piston 丨 4a will be sucked and compressed and pushed forward until the compressed gas is sent to the outer ring tube through the inner through-hole 122 In the airtight space 112, it is discharged through the exhaust opening 10b connected to the i airtight space m. Then, the piston ... is no longer affected by the magnetic force, and because of the frictional force between itself and the inner annular tube 12, it decelerates until it passes through the solenoid coils 15a to 15e and then enters another pressure stroke, so the cycle is endless. .

On the other hand, in order to improve the natural deceleration effect of the pistons 14a to 14e, the speed of the pistons 14a to 14e can be quickly reduced to one without relying on any external force, such as electromagnetic force, before entering the next compression stroke.

Description of the invention (6) Laminated silicon steel sheet assembly 141 composed of sheets, a permanent magnet 142, = heat of steel = ring 143, two metal fixing caps "4, two rubber stoppers, 145, a gasket 146 and two fixing bolts. The layered Shixi steel sheet assembly 1 4 1 with σ has a central through hole 1 4 1 a and two opposite grooves 1 4 1 b. The center book recites m —, ^ Jiaxin Beitong The hole 1 41 a is used to receive the permanent magnet 142 to increase the magnetic force between the piston 14 a and the electromagnetic coils 15 a to 15 e, and the groove 1 4 1 b is used to create an air gap. 14a is automatically guided by the magnetoresistance effect near the air gap 153 of the electromagnetic coils 15a to 15e, so that the magnetic circuit impedance formed by the layered silicon steel sheet assembly 141 and the electromagnetic coil 15a is the smallest. Therefore, it is ensured that the magnetic force written by the piston 14a is a maximum value. Therefore, as long as the magnetic circuit impedance formed by the layered silicon steel sheet assembly 14 and the electromagnetic coil 15a is the smallest, the condition of the groove 1411 can be achieved. In addition to the rectangle shown in FIG. 2D, the outline may also have other shapes—for example, an arc shape. In addition, the Shixi steel sheet assembly 141 is accommodated in the piston collar 143, and is fixed by two metal fixing caps 1 4 4 installed at both ends of the piston collar 1 4 3. Further, each metal fixing cap 144 The upper part is provided with a rubber plug 145, which is used to provide the required surface of the compressed gas, and to reduce the noise caused by the piston when moving inside the inner ring tube. 2. Then, the gasket is used, and the fixing bolt is used. 47 to fix these metal fixing caps 144 and rubber plugs 145. Referring to Fig. 3, in the second embodiment, the airtight space 112 of the electromagnetic rotary piston pump 1 of the present invention can also use other annular partition plates 13c. , 13d, 1 3e are further divided into four airtight spaces 丨 13, i 14,} 15 & i 丨 6, and rows are arranged in each airtight space 1 1 3, 1 1 4, 1 1 5 and 1 1 6 Gas openings Page 15 1233468 V.

Please refer to FIG. 4. In the third embodiment, the electromagnetic rotary piston pump of the present invention can also be used. It can be connected in series to have a multi-stage boosting function. For example, the exhaust opening 10b of an electromagnetic rotary piston pump 1 can be connected in series with the intake opening 2a of an electromagnetic rotary piston pump 2. The exhaust opening 2 0 b of the electromagnetic rotary piston pump 2 is connected in series with the intake opening 3 0 a of an electromagnetic rotary piston pump 3, and so on. In this way, we can finally pass the exhaust opening 3 0 b Get higher pressure and higher air volume. As mentioned above, since the piston of the electromagnetic rotary piston pump of the present invention rotates continuously in the inner annular tube, it does not need a check valve to generate and generate continuous pressure, and reaches the same pressure range as the conventional reciprocating pump. In addition, the electromagnetic energy loss of the electromagnetic rotary piston pump of the present invention is only related to the friction of the piston during acceleration, so it can effectively reduce the electromagnetic energy loss and improve the work efficiency. In addition, it should be noted that although this embodiment The outer ring is made of plastic, but the material of the outer ring is not limited to this. Similarly, the material of the inner ring pipe is not limited to brass, but can be other materials with low friction coefficient. In addition, the phase difference between the intake opening and the exhaust opening of the present invention is not limited to 180 degrees, and may be changed according to design requirements. In summary, the present invention has been described in detail through the above-mentioned embodiments and modified examples.
