Description

Fluid booster

The present invention relates to a fluid pressurizing device, and more particularly to a fluid pressurizing device installed in a fluid delivery line.

When the fluid flows in the conveying pipeline, the flow velocity of the fluid flowing through the pipeline is reduced due to the excessive length of the pipeline, the bending of the pipeline or the friction between the fluid and the inner wall of the pipeline, and the flow rate of the fluid is caused. insufficient. To solve this problem, a fluid pressurizing device for increasing fluid pressure and flow can be installed in the fluid delivery line.

The fluid pressure boosting device is mainly divided into a power boosting device and a non-powered boosting device, wherein the conventional power boosting device drives a pump or a piston by a power component (for example, a motor) to directly pressurize the fluid. It flows into the delivery line at a higher flow rate, thereby significantly increasing the flow of fluid through the line. However, the conventional power booster requires power output from the power component and can be operated in conjunction with a pump or piston structure. It has a problem of excessive cost, and is difficult to be widely applied to various fluid transfer pipelines, and is not in line with today's society. The trend of carbon.

On the other hand, the conventional unpowered supercharger mainly forms a reduced diameter portion at the nozzle opening of the delivery line so that when the fluid flows through the reduced diameter portion, it can be instantaneously pressurized. Although the conventional unpowered supercharging device can also increase the flow rate and pressure of the fluid flowing out of the conveying pipeline, the utility model has the advantages of simple structure and low cost, but the passive pressurization method has limited supercharging effect due to lack of external power source. And the actual flow of fluid flowing through the pipeline cannot be actually increased, which seriously affects its practicability.

In summary, there is an urgent need to develop a further improved fluid pressurization device to improve the disadvantages of the poor pressurization effect of the conventional unpowered booster device, so as to provide a low cost and can be widely applied to various fluid transfer pipelines. Fluid booster.

The above and other objects, features and advantages of the present invention will become more <RTIgt;

Referring to FIG. 1 , a fluid pressure device 1 according to a preferred embodiment of the present invention includes a housing 11 . The housing 11 defines an accommodation space R therein, and the housing 11 is preferably tubular. The two ends are respectively a first opening 111 and a second opening 112. The first opening 111 and the second opening 112 respectively communicate with the accommodating space R.

The first impeller 12 and the second impeller 13 are respectively disposed in the accommodating space R of the casing 11. The first impeller 12 is pivotally disposed in the accommodating space R through a rotating shaft 121. The second impeller 13 is also pivotally disposed in the accommodating space R through a rotating shaft 131. The first impeller 12 and the second impeller 13 are preferably at the first opening 111 And the second openings 112 are arranged opposite to each other. In addition, the structure of the first impeller 12 and the second impeller 13 may be the same, that is, have the same number of blades, blade size, blade shape and blade angle, so that the first impeller 12 and the second impeller 13 are respectively identical. When the rotational speed is rotated, the same driving force can be generated for the same fluid, but the invention is not limited thereto.

The rotating shaft 121 of the first impeller 12 and the rotating shaft 131 of the second impeller 13 can be respectively connected to two ends of a speed reducing device 14 for connecting the first impeller 12 and the second impeller 13 A speed difference is generated. In detail, the reduction gear unit 14 can be a gear reducer, a planetary gears, a worm wheel reducer, a cycloid reducer or a harmonic reducer. Drive) and other conventional deceleration structures, the invention is not limited thereto. As shown in FIG. 2 , in the embodiment, the reduction gear 14 can be a reduction gear set including a first drive gear 141 and a second drive gear 142 , the first drive gear 141 and the The second driving gears 142 are respectively coupled to the rotating shaft 121 of the first impeller 12 and the rotating shaft 131 of the second impeller 13 to be rotated by the two rotating shafts 121 and 131, respectively. The reduction gear unit 14 further has a driven gear set 143 that meshes with the first drive gear 141 and the second drive gear 142, respectively.

In the present embodiment, the driven gear set 143 includes a first driven gear 143a and a second driven gear 143b. The first driven gear 143a and the second driven gear 143b can be pivoted synchronously. The first driven gear 143a and the second driven gear 143b are respectively meshed with the first driving gear 141 and the second driving gear 142. With the above structure, when the rotating shaft 121 of the first impeller 12 rotates, the first driving gear 141, the first and second driven gears 143a, 143b and the second of the driven gear set 143 are sequentially driven. The driving gear 142 rotates to drive the rotating shaft 143 of the second impeller 13 to rotate; otherwise, when the rotating shaft 143 of the second impeller 13 rotates, the rotating shaft 121 that drives the first impeller 12 also rotates. Accordingly, the rotating shaft 121 of the first impeller 12 and the rotating shaft 131 of the second impeller 13 are interlocked. In other words, the first impeller 12 and the second impeller 13 can rotate with each other and pass through the same. The speed reducing device 14 can generate a rotational speed difference between the first impeller 12 and the second impeller 13.

More specifically, the reduction gear unit 14 is a reduction gear set, and the first drive gear 141, the second drive gear 142, the first driven gear 143a and the second driven gear 143b are appropriately selected. The number of teeth can be such that the reduction gear unit 14 has a reduction ratio, which is the ratio of the rotation speeds of the first impeller 12 and the second impeller 13. For example, if the first driving gear 141, the second driving gear 142, the first driven gear 143a, and the second driven gear 143b have 〝20〞, 〝10〞, 〝10〞, and 〝20, respectively When the rotating shaft 121 of the first impeller 12 rotates once, the first driving gear 141 is rotated once, and the number of teeth of the first driving gear 141 and the first driven gear 143a is rotated. The first driving gear 141 will drive the first driven gear 143a to rotate two times. The first driven gear 143a and the second driven gear 143b are synchronously pivoted, so the second driven gear 143b also rotates two times, and the second driven gear 143b and the second driven gear 142 The number of teeth is 〝20〞 and 〝10〞, respectively, so the second driven gear 143b will drive the second drive gear 142 to rotate four times.

Therefore, if the first drive gear 141 and the second drive gear 142 are respectively regarded as the input end and the output end of the reduction gear device 14, the reduction ratio of the reduction gear device 14 is 〝1:4〞, that is, When the first impeller 12 rotates at a rotational speed, the second impeller 13 is synchronously rotated at four times the rotational speed, so that a rotational speed difference is generated between the first impeller 12 and the second impeller 13.

It should be noted that the reduction gear set is a prior art that can be understood by those skilled in the art. The structure of the above-mentioned reduction gear 14 is only one of the embodiments. The reduction device 14 has a plurality of different implementations, and can be first. A difference in rotational speed is generated between the impeller 12 and the second impeller 13, and the invention is not limited thereto.

Referring to FIG. 3, when the fluid pressure device 1 of the present invention is actually used, a delivery line P may be coupled to the first opening 111 or the second opening 112 of the housing 11 to The fluid pressure device 1 is installed in the delivery line P, but the fluid pressure device 1 can also be installed inside the delivery line P, and the inner wall of the housing 11 and the delivery line P A tight fit is formed, and the invention is not limited thereto. When the delivery line P is used to transport a fluid (for example, a gas or a liquid), and the fluid flows through the fluid pressure device 1, if the fluid flows from the first opening 111 into the accommodating space R, The flow system first flows through the first impeller 12 and drives the first impeller 12 to rotate. When the first impeller 12 rotates at a rotational speed, the second impeller 13 is synchronously rotated at four times the rotational speed, so that there is a rotational speed difference between the first impeller 12 and the second impeller 13 When the two impellers 13 rotate, the fluid will be driven to flow at a higher flow rate, which can effectively increase the flow rate of the fluid flowing out of the second opening 112, thereby achieving the effect of increasing the pressure of the fluid in the delivery line P.

It should be noted that if the first drive gear 141 is used as the output end of the reduction gear 14 and the second drive gear 142 is used as the input end of the reduction gear 14, the reduction ratio of the reduction gear 14 will be 〝4:1〞, that is, when the second impeller 13 rotates at a rotation speed, the first impeller 12 is synchronously rotated at a quarter of the rotation speed, so that the first impeller 12 and the second impeller 13 A speed difference is generated between them.

Accordingly, if the fluid flows into the accommodating space R from the second opening 112, the flow system first flows through the second impeller 13 and drives the second impeller 13 to rotate. When the second impeller 13 rotates at a rotation speed, the first impeller 12 is synchronously rotated at a quarter of the rotation speed, so that there is a rotation speed difference between the first impeller 12 and the second impeller 13. When the first impeller 12 rotates, the fluid will be driven to flow at a lower flow rate, which can effectively reduce the flow rate of the fluid flowing out of the first opening 111, thereby achieving the effect of reducing the pressure of the fluid in the delivery line P. .

Referring to FIG. 4, the fluid pressurizing devices 1, 1' of the present invention can be combined with each other. For example, the second opening 112 of the fluid pressurizing device 1 can be the same as the fluid pressurizing device 1'. An opening 111' is combined. Thereby, if the structure of the fluid pressurizing device 1' is When the fluid pressure boosting device 1 is identical, when the first impeller 12 of the fluid boosting device 1 rotates at a rotational speed, the second impeller 13 is synchronously rotated at four times the rotational speed. The fluid in the delivery line P is driven by the rotation of the second impeller 13 to flow out of the second opening 112, and flows into the accommodating space R' by the first opening 111' of the fluid pressure device 1'. The first impeller 12' is also driven to rotate at four times the rotational speed, causing the second impeller 13' to be driven to rotate at sixteen times the rotational speed.

In other words, when the delivery line P is used to deliver a fluid and the fluid flows through the fluid pressure device 1, if the fluid flows from the first opening 111 into the accommodating space R, the flow system first flows. Through the first impeller 12, and driving the first impeller 12 to rotate, since the first impeller 12 rotates at a rotation speed, the fluid is synchronously driven to flow through the second impeller 13 of the fluid pressure device 1' at the rotation speed. The sixteenth rotation, so that a larger one can be provided between the first impeller 12 of the fluid pressurizing device 1 and the second impeller 13 of the fluid pressurizing device 1' than in the case of only a single fluid pressurizing device 1. The rotational speed difference is such that the fluid is driven to flow out of the second opening 112' at a higher flow rate. Accordingly, the body pressurizing devices 1, 1' are combined with each other, and the supercharging effect of the fluid in the transport line P can be further enhanced.

Referring to FIG. 5, a fluid pressurizing device 2 according to another preferred embodiment of the present invention is different from the previous preferred embodiment in that three housings R of the housing 21 are provided. The above impeller includes a first impeller 22, a second impeller 23 and a third impeller 26. In detail, similar to the foregoing preferred embodiment, the first impeller 22, the second impeller 23, and the third impeller 26 are pivotally disposed in the accommodating space R through a rotating shaft 221, 231, and 261, respectively. The first impeller 22 , the second impeller 23 , and the third impeller 26 are preferably arranged opposite to each other between the first opening 111 and the second opening 112 . The rotating shaft 221 of the first impeller 22 and the rotating shaft 231 of the second impeller 23 are respectively connected to two ends of a speed reducing device 24, and the rotating shaft 231 of the second impeller 23 and the rotating shaft of the third impeller 26 The 261 can also be connected to the two ends of the other reduction device 25, respectively. The reduction device 24 and the reduction device 25 can be implemented as described above For example, the reduction gear unit 14 has the same reduction gear set.

With the above configuration, when the first impeller 22 of the fluid pressurizing device 2 is rotated at a rotation speed, the second impeller 23 is synchronously rotated by the deceleration device 24 at four times the number of revolutions. Since the rotating shaft 231 of the second impeller 23 is further connected to the rotating shaft 25, when the second impeller 23 rotates four times of the rotating speed, the third impeller 26 is synchronously driven via the speed reducing device 25 at ten Six times rotation.

In other words, when the delivery line P is used to deliver a fluid and the fluid flows through the fluid pressure device 2, if the fluid flows from the first opening 211 into the accommodating space R, the flow system first flows. The first impeller 22 is rotated by the first impeller 22, and when the first impeller 22 rotates at a rotation speed, the third impeller 26 is synchronously driven to rotate at a rotation speed of sixteen times. For example, the fluid pressurizing device 1 can provide a larger rotational speed difference between the first impeller 22 and the third impeller 26 of the fluid pressurizing device 2 to drive the fluid to flow out of the second opening 212 at a higher flow rate. . Accordingly, by increasing the number of impellers in the fluid pressurizing device 2, the effect of supercharging the fluid in the delivery line P can be effectively enhanced.

In summary, the fluid pressure boosting device of the present invention utilizes at least two impellers in a housing, and any two adjacent impellers are respectively connected to a deceleration device, and when one of the impellers rotates, the deceleration device is driven. The other impeller rotates at a different rotational speed, and the fluid pressure in a delivery line is adjusted by the difference in rotational speed generated between the at least two impellers. Accordingly, the fluid pressurizing device of the present invention can indeed increase the pressure of a fluid, thereby achieving the effect of increasing the flow rate of the fluid.

Furthermore, the fluid pressurizing devices of the present invention can be combined with one another such that a greater rotational speed difference between the impellers in the different fluid pressurizing devices is used to drive the fluid in a delivery line to flow at a higher flow rate, indeed Achieve further enhanced boost effect.

While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention.
