[DESCRIPTION] [Invention Title] Impeller with Cylindrical Vanes [Technical Field] [1] This invention pertains to the impeller; to be more specific, multiple hollow vanes form spiral in one direction from the center of the base plate so that the fluid flows into the hollow housing which in turn flows into inlet ports through spin of the impeller Fluid that flowed in will flow into the multiple vanes through the inlet and discharged through outlet ports of multiple vanes which are formed in the center of the base plate. This impeller with cylindrical vanes minimizes friction with the fluid, thereby maximizing the hydraulic head and overall efficiency. [2] [Background Art] [3] In traditional architectural method of the impeller, main variables that are needed for the meridian plane and overall architecture are determined through basic theories regarding the pump and also based on the past experiences. When structure of the vane is being determined, vane's entrance angle and exit angle are usually decided by meridian plane's image or based on the past experiences. Sweep angle, which is related to the length of the vane is designed to connect the set entrance and exit angle smoothly and therefore included in the determining value and not as an important variable. Moreover, it is possible to show the shape of the impeller through vane planar diagram. [4] When the impeller is being designed, there are numerous design related variables that shows three dimension image of the impeller from the meridian plane and the planar diagram for the wing. Analyzing how much effect design variables have on the efficiency of the centrifugal pump is a very important process in order to secure the technology regarding the pump design. [5] Traditionally, impellers are composed of base plate, side plate, vane and pivot. By spinning the pivot, liquid flows in to the inlet port. The liquid is discharged through the passage created with base plate and the side plate to add energy to the liquid. [6] Vane of the above mentioned impeller connects the base plate and the side plate as multiple impellers' vanes are arranged in radial shape and each vane of the impeller is formed by bending to certain degrees. The bent impeller's vane has concaved part and a protruding part. Concaved part as mentioned above has low pressure from the fluid compared to the protruding part. Therefore, efficiency of the impeller is lowered as flow of the liquid is desquamated in the concaved part of the impeller's wing which in turn causes countercurrent. [7] Moreover, as there are limited numbers of vanes in the impeller and since liquid has viscosity; relative speed at the exit of the impeller differs from the angle of the exit in the vane. Direction of the liquid discharge has huge difference from the exit angle of the vane as numbers of vanes are reduced. [8] By this phenomenon, sliding velocity is produced in the impeller's exit and as the sliding 1 velocity occurs in opposite direction of the spinning direction of the impeller this causes the pressure head of the impeller to decrease. As sliding velocity gets bigger, main speed should be increased in order to generate an equal amount of pressure. This in turn decreases the efficiency and the usefulness of the impeller: [9] There is a possibility that impeller's efficiency could be increased if factors hindering the efficiency such as decreased Performance of the impeller which leads to increase of the shaft power that moves the impeller: [10] In case where the impeller has small ratio in the width of the exit, there is only a small difference in side plate and the base Plates' bend radius. Moreover, passage of the vane is long and the flow within the vane's passage does not decrease but increased in general even if the static Pressure is lessened in the entrance of the side plate. Therefore, in spite of pressure increase in the vane's passage where the counter pressure increases significantly, the flow in the side plate is not desquamated. [11] In case of impeller that has a big ratio in the width of the exit, there is a big difference in the side plate and the base plates' bend radius. Moreover, wing's passage is short and the flow that sped up and started from the entrance of the side plate will slow down significantly when it reaches the exit of the impeller. Distribution of speed in the impeller's exit increases greatly in the side plate compared to the entrance of the base Plate. [12] When side plate follows inner surface of the wall, flow phenomenon similar to that of the flow structure where there is a strong flow with increased counter pressure occurs. This causes a strong desquamate to occur in the side plate where the flow is continued. Through the desquamated flow, vane's passage in the inner wall is completely blocked, thereby forming a strong countercurrent in the exit of the side plate. [13] By following side plate's inner surface of the wall, flow phenomenon similar to that of the flow structure where there is a strong flow with increased counter pressure occurs. This causes a strong desquamate to occur in the side plate where the flow is continued. Through the desquamated flow, wing's passage in the inner wall is completely blocked, thereby forming a strong countercurrent in the exit of the side plate. [14] When this phenomenon occurs, desquamated flow completely blocks the side plate's inner wall surface in the wing's passage. This greatly decreases the flow velocity in the side plate's exit and sliding velocity rapidly increases which in turn reduces the pressure formation that decreases the efficiency and the usefulness of the impeller. [15] The preexisting impeller is explained through figure 1. In the figure 1, it shows the impeller (1) which is includes boss (2) that serves as the passage where fluid flows in for the first time, upper plate (3) that supports the lower part of the boss (2) as it is formed as one with the boss (2), base plate (4) located in the lower part of the upper plate (3) and number of vanes (5) formed as a spiral on the bottom. Impeller (1) as mentioned above has a wall with certain space in vertical direction of the upper plate (3) and the base plate (4). Therefore, the fluid that came in through boss (2) is discharged through the space between the walls. 2 Moreover, in case of the preexisting impelle, cross sectional areas of the space which is formed in upper plate (3), base plate (4) and the walls are square shaped, thus causing the whirlpool to occur which is problematic. [16] As the whirlpool occurs, it disrupts smooth flow of the fluid which decreases the efficiency of the impeller. [17] Moreover, this causes the impeller (1) which is as mentioned above causes the fluid that doesn't get flown in to the boss (2) to collide with the upper plate (3) when the fluid is flow in to the impeller (1). This in turn causes the loss of friction which leads to loss of energy. [18] [Disclosure] [Technical Problem] [19] Purpose of this invention which seeks to solve the problems as mentioned above is to provide the impeller with cylindrical vanes which minimizes friction with fluid and increases hydraulic head and the efficiency at the same time. The impeller as mentioned above achieves these results by multiple hollow vanes forming spiral in one direction from the center of the base plate so that the fluid flows into the hollow housing which in turn flows into inlet ports through spin of the impeller. Fluid that flowed in will flow into the multiple vanes through the inlet and discharged through outlet ports of multiple vanes which are formed in the center of the base plate. [20] Moreover, purpose of this invention is to provide the impeller with cylindrical vane where base plate supports one side of vane's outer circumference as vane and the base plate is formed as one. [21] Moreover, purpose of this invention is to provide the impeller with cylindrical vane that can provide structural stability through forming the base plate, vane and the inlet as one. [22] Moreover, purpose of this invention is to provide the impeller with cylindrical vane that can minimize the risk that comes from friction with the fluid that flows in other places because one vane's outer circumference and another vane's outer circumference which is close to another vane is separated. [23] Moreover, purpose of this invention is to provide the impeller with cylindrical vane that enables the smooth flow of the fluid that flows into the inside from the inlet as the apex is formed in the upper part of the base plate. [24] [Technical Solution] [25] In order to solve the problems as mentioned above, impeller with cylindrical vane which is in accordance with this invention includes the impeller with inlet port and hollow vane. The vane as mentioned above has an inlet has a funnel that connects to the inlet port. Through this, the fluid that passed through the inlet port as mentioned above will be discharged through the vane as 3 mentioned above. And the shape of the above mentioned vane is circular or elliptical and the characteristic is that it gradually increases from the above mentioned inlet port to the above mentioned outlet port. [26] Ideally above mentioned impeller includes base plate which is one with above mentioned vane. And the vane as mentioned above has the characteristics of supporting one side of vane's outer circumference. [27] Ideally, base plate, vane and inlet as mentioned above are formed as one as its characteristics. [28] Ideally, one vane's outer circumference which is from the multiple vanes as mentioned above and another vane as mentioned above which is close to another vane's outer circumference are separated as one of its characteristics. [29] Ideally, base plate as mentioned above includes the apex formed on the top of the above mentioned base plate as one of its characteristics. [30] [Advantageous Effects] [31] As mentioned above, this invention's purpose is as follows: multiple hollow vanes forming spiral in one direction from the center of the base plate so that the fluid flows inside which minimizes friction with the fluid, thereby maximizing hydraulic head and the overall efficiency. [32] Moreover, this invention forms the vane and the base plate as one which causes the effect of the base plate supporting one side of the vane's outer circumference. [33] Moreover, this invention forms base plate, vane and the inlet as one which provides structural stability as one of its effects. [34] Moreover, one of the effects of this invention is that it minimizes the friction with the fluid that results in a loss which happens as one's outer circumference which is from the multiple vanes and another vane which is close to another vane's outer circumference are separated. [35] Moreover, this invention eases the flow of the fluid that flows in to the inner part of the inlet as apex is formed on the top of the base plate. [36] [Description of Drawings] [37] Figure 1 is the slanted diagram of the traditional impeller from one view point. [38] Figure 2 is the diagram that helps understand the impeller with cylindrical vane of this invention from view point of the pump as an example, and [39] Figure 3 is a slanted diagram of the impeller with cylindrical vane of this invention from one point of view as an example. [40] 4 [Detailed Description of Exemplary Embodiments] [41] The impeller with cylindrical vane of this invention (100) has a good example in Figure 1 and Figure 3 for further reference. During this process, thickness of the lines in the figure or the size of the components may have been exaggerated for clearer explanation and for convenience. Moreover, terminologies that are used are defined in regards to the function of this invention. The terminologies are subject to change in regards to the user, operator's intent or according to the customs. Therefore, definition of these terms should be depicted according to the content of this specification. [42] Area that above mentioned invention applies to is about the pump; it is especially about the centrifugal pump. The centrifugal pump is a well-known hydraulic machine where it converts the mechanical energy into hydraulic pressure and kinetic energy by receiving the energy from the outside and through the spinning impeller. It should be noted that hydraulic head, efficiency, shaft power and other things regarding the centrifugal pump is affected greatly according to the number of impeller vanes, change in form and number of spins. [43] On the other hand, the term 'transverse cross section area' in this invention refers to fluid moving vertically in the cross sectional area in the vane. [44] Also, the term 'longitudinal cross section area' in this invention refers to fluid moving in the cross sectional area in the vane. [45] [46] The important parts needed to explain this invention, impeller with cylindrical vane (100) are as follows. [47] Housing (10) forms the outer part of the pump and enables impeller with cylindrical vane (100) to be located inside the housing (10). This housing (10) should be able to withstand the fast spins of the pump type impeller (100) powered by the motor (30) which will be discussed later. For this reason, it is recommended that strong material be used such as a material that has high wear and corrosion resistance that can withstand the water pressure and the friction caused by the movement of the fluid impeller with cylindrical vane. [48] The pivot (20) is located in the central lower part of the impeller with cylindrical vane (100). This pivot (20) carries out the task of delivering the motor's (30) rotational force, which will be discussed later, to the impeller (100). [491 The motor (30) enables the impeller (100) to rotate by delivering the rotational energy to the pivot (20). [50] [Industrial Applicability] [51] In the description below, impeller with cylindrical vane (100) of this invention will be described. [52] The impeller with cylindrical vane (100) of this invention includes the base plate (101), inlet port where the fluid first flows in, (102) multiple numbers of vanes (104a, 104b, 104c, 104d, 104e) connected to the base plate (101), multiple numbers of inlet ports (105a, 105b, 105c, 105d, 105e) that are formed in one side of the multiple numbers of vanes (104a, 104b, 104c, 104d, 104e), and multiple numbers of outlet ports (106a, 106b, 106c, 106d, 106e) fo rmed on the other side of the multiple numbers of vanes. (104a, 104b, 104c, 1046, 104e) [53] Following will be explained in detail in the order as below: base plate (101), inlet port (102), multiple numbers of vanes (104a, 104b, 104c, 104d, 104e), multiple numbers of inlet ports (105a, 105k, 105c, 105d, 105e), and multiple numbers of outlet ports (106a, 106b, 106c, 106d, 106e). [54] Base plate (101) has the function of supporting multiple numbers of vanes (104a, 104b, 104c, 104d, 104e) and this base plate (101) includes the apex (103). [55] Inlet port (102) is composed of cylinder open to the top and bottom and the inlet port (102) works as the passage so that the fluid would be flown in for the first time. [56] Apex (103) is formed on topmost part of the base plate (101). This apex (103) is going to minimize the friction of the fluid which flows in through the inlet port (102) and does the task of sending the fluid in to the multiple numbers of vanes (104a, 104b, 104c, 104d, 104e). [57] Multiple numbers of vanes (104a, 104b, 104c, 104d, 104e) is formed in cylinder and formed to be bent in one direction. It is especially recommended that it would be bent over the same direction as pivot (20) and motor (30) spin. This is because it will minimize the friction with the fluid and consequently increase the efficiency of the pump. [58] Moreover multiple numbers of vanes (104a, 104b, 104c, 104d, 104e) is formed with circular or cylindrical and it is recommended that it will gradually increase from inlet port towards the outlet port. [59] For example, observing the traditional impeller (1) as seen in the figure 1, it is shown that as cross sectional areas is formed in square shape which could cause the loss of shaft power due to the whirlpool phenomenon. Through this invention, whirlpool phenomenon is eliminated as it had been stated earlier and it helps the fluid move smoothly and minimizes the loss of shaft power. These multiple numbers of vanes (104a, 104b, 104c, 104d, 104e) carry out the task of being the passage that passes the fluid through the inlet port (102) which includes the of inlet ports (105a, 1.05, 105c, 105d, 105e) and outlet ports (106a, 106b, 106c, 106d, 106e). [60] Multiple numbers of inlet ports (105a, 105b, 105c, 105d, 105e) is located in the base plate's (101) center and in the side of multiple numbers of vanes (104a, 104b, 104c, 1046, 104e). The multiple numbers of inlet ports (105a, .05b, 105c, 105d, 105e) carry out the task of making the fluid that came in through the inlet ports (105a, 105b, 105c, 105d, 105e) flow into the multiple numbers of vanes (104a, 104b, 104c, 104d, 104e). [61] Multiple numbers of vanes (104a, 104b, 104c, 104d, 104e) is located in the left side of the base plate (101) and another side of multiple numbers of vanes (104a, 104b, 104c, 104d, 104e). The multiple numbers of vanes (104a, 104b, 104c, 104d, 104e) carry out the task of discharging the fluid that flows into multiple number of inlet ports (105a, 105b, 105c, 105d, 105e) and discharge it outward. [62] 6 [63] The multiple numbers of vanes (104a, 104b, 104c, 104d, 104e), inlet ports (105a, 105b, 105c, 105d, 105e), and outlet ports (106a, 106b, 106c, 106d, 106e) that were mentioned previously are formed in five each as shown in figure 2 but as the efficiency of the pump and hydraulic head may change according to the number of the vanes, user may change the number and use it. [64] [65] As mentioned above, impeller with cylindrical vane (100) as this invention is going to spin with the pivot (20) by the motor. This is when the fluid that came through the inlet port (102) goes through the inlet ports (105a, 105b, 105c, 105d, 105e) by spinning impeller with cylindrical vane (100). The fluid passes through multiple numbers of vanes (104a, 104b, 104c, 104d, 104e) and ultimately discharged through outlet ports (106a, 106b, 106c, 106d, 106e). [66] [67] As stated above, there were good examples for the invention but anyone with the knowledge of the industry would know that this invention can be edited and changed in various ways as long as it does not go out of bounds of the area and the idea as stated in the patent specification. 7
