Pump suction guide device having a blade and method of using the same {PUMP SUCTION GUIDE APPARATUS WITH BLADES AND METHOD FOR USE THEREOF}

The present invention relates to a technology for guiding the suction of a fluid pumped by a submersible pump, and more specifically, a turbulence prevention device is installed at the lower part of the inlet of the submersible pump to discharge floating matter and improve the flow of the fluid. By doing so, it relates to a pump suction guide device having a blade to improve the suction capacity of a submersible pump and a method of using the same.

A pump is a generic term for a machine that transports fluid through a pipe by means of pressure or pressurizes a fluid in a low-pressure container into a high-pressure container through a pipe. And, among these pumps, a submersible pump refers to a pump capable of pumping water in a state in which a pump and an electric motor for driving the pump are integrated and put into water.

1 is a view showing a state in which such a submersible pump is installed in a water tank or a pumping station.

The submersible pump 10 is put into a water tank or pumping station to raise fluid. At this time, the shape of the water tank or pumping station, the arrangement of the submersible pump 10, and the relationship between the submersible pump 10 and the bottom surface 30 of the water tank or pumping station Turbulence may occur inside the tank due to various installation environments such as height. Here, the turbulent flow means flowing with an irregular motion temporally or spatially. Turbulence is divided into vortex and swirl. The vortex means that there is no direction among turbulent flows, and the swirl means that there is direction.

When turbulence occurs during the operation of the submersible pump 10, air flows into the suction port of the submersible pump, causing vibration and noise. In addition, not only this, but also the performance of the submersible pump is lowered, the discharge amount is reduced, and the problem of overloading the motor is also generated.

2 and 3 are views showing the shape and use method of a conventional pump suction guide device.

In general, in order for the submersible pump 10 to smoothly suck in and transfer the fluid, the height of the inlet of the submersible pump 10 should be installed at a distance equal to or greater than the caliber of the submersible pump 10 . That is, the height of the suction port of the submersible pump 10 must be spaced apart from the bottom surface 30 of the water tank by a diameter of the submersible pump 10 or more. If the inlet of the submersible pump 10 is located lower than this, the fluid is not properly supplied into the inlet of the submersible pump 10, and the performance of the submersible pump 10 deteriorates. It is formed to cause noise or vibration to the submersible pump 10. Therefore, it is preferable to install the suction port so as to be spaced apart from the bottom surface 30 of the water tank or pumping station by the length of the aperture of the submersible pump 10 in order to maximize the suction capacity of the submersible pump 10.

4 to 7, the pump suction guide device 140 having a blade according to the present invention includes an impeller 120 and a support 130 for supporting the impeller 120 on the bottom surface 30 includes

The impeller 120 may include a brush 124 formed at the other end. Here, the other end may mean the lowermost surface of the impeller 120 . The brush 124 rotates along the impeller 120 while being in close proximity to or lightly contacting the bottom surface 30 .

Therefore, the brush 124 helps the floating matter remaining on the bottom surface 30 to float in the water, thereby preventing the floating matter from remaining on the bottom surface 30.

The shape of the impeller 120 may be implemented in various ways. For example, the impeller 120 may be implemented in a shape in which the aperture gradually decreases from the other end to one end as shown in FIG. 7 . Here, the other end means a lower end, and one end means an upper end.

The impeller 120 may have outer blades 121A and/or inner blades 121B. As the fluid is sucked by the operation of the submersible pump 10, the outer blades 121A and/or the inner blades 121B rotate the impeller 120 by the fluid to improve the flow of the fluid. Here, the meaning that the flow of the fluid is good means that the fluid sucked into the submersible pump 10 is sucked into the submersible pump 10 with a constant direction and speed. Accordingly, the suction ability of the submersible pump 10 is improved. These blades may be implemented in various forms. Here, the submersible pump 10 means a submersible pump installed in water.

5 shows that the fluid sucked into the submersible pump 10 by rotation of an impeller having outer blades 121A and/or inner blades 121B moves through the submersible pump 10 with a constant direction and speed. It is shown as an example of inhalation.

8 is a detailed view of an impeller in a pump suction guide device having blades, and FIG. 9 (a) and (b) are diagrams schematically showing blades formed in the impeller of FIG. 10 (a) and (b) are views showing a side view in order to examine in more detail the shape in which the outer blade and the inner blade are tilted in one direction or the other direction. .

As a first embodiment of the blade, the impeller 120 may include one or more outer blades 121A formed on an outer surface. The flow of fluid is improved by the outer blade 121A provided in this way.

As a second embodiment of the blade, the impeller 120 may include one or more inner blades 121B formed on an inner surface.

As a third embodiment of the blade, the impeller 120 may include one or more outer blades 121A formed on an outer surface and one or more inner blades 121B formed on an inner surface. In this case, since a water flow is formed on the outer surface of the impeller 120 and also on the inner surface, the suction capability of the submersible pump 10 can be further improved.

The outer blades 121A may be inclined on the outer surface of the impeller 120 so that the pressure surface 122 and the suction surface 123 are formed. Similarly, the inner blades 121B may be inclined on the inner surface of the impeller 120 so that a pressure surface and a suction surface are formed. Here, the pressing surface 122 means an upper side with respect to the outer blade 121A when looking at the impeller 120 from above through the drawings, and the suction surface 123 means a lower side. Here, the inclination directions of the outer blades 121A and the inner blades 121B may be implemented in various forms. For example, the outer blade 121A may be inclined by an angle of θ1 in one direction as shown in (a) of FIG. 10, and the inner blade 121B may have an angle of θ1 in one direction and the opposite direction as shown in (b) of FIG. It may be formed to be inclined by an angle. For reference, θ1 is an acute angle less than 90 degrees.

Here, the pressure surface 122 is a surface that provides pressure to the fluid according to the rotation of the impeller 120 and pushes it out, and the suction surface 123 is a surface through which fluid is introduced according to the rotation of the impeller 120. refers to the side In general, in the case of an impeller mounted on a submersible pump, it is rotated by a driving source, so the surface forming an acute angle with the outer surface of the blade provides pressure to the fluid and becomes a pressure surface, and the surface forming an obtuse angle with the outer surface of the blade. Since the fluid is introduced through the , the corresponding surface becomes the suction surface. However, since the impeller 120 constituting the pump suction guide device having blades according to the present invention operates passively according to the fluid sucked by the operation of the submersible pump 10, the surface forming an obtuse angle is the pressure surface 122 It can act as, and the surface forming an acute angle can act as the suction surface 123. For reference, it should be noted that the classification of the suction surface and the pressure surface in the present invention is divided into whether pressure is provided or suctioned based on the fluid. For example, when the impeller 120 of FIG. 8 actively rotates counterclockwise, the surface forming an acute angle becomes the pressure surface 122 and the surface forming an obtuse angle becomes the suction surface 123, which is a submersible pump ( If it is operated passively by the rising water flow by 10), the water flow pushes the surface forming an acute angle to become a suction surface 123, and since the opposite surface pressurizes the fluid, it can be referred to as a pressure surface 122. For reference, it is necessary to keep in mind that this is strictly classified for the purpose of explaining the present invention, and it can also be used as the same meaning as the impeller 120 operating in the submersible pump 10 even when operated passively or passively. However, it should be noted that there is no change in the fact that the outer blades 121A and the inner blades 121B tilt in either direction no matter how they are described.

The reason why the outer blades 121A are inclined on the outer surface of the impeller 120 so that the pressure surface 122 and the suction surface 123 are formed in this way is to provide a certain direction and speed to the water flow starting from the lower part of the impeller 120. This is to ensure that it is concentrated into the inlet of the submersible pump (10).

As shown in (a) of FIG. 10 , the outer blades 121A may be inclined in one direction on the impeller 120 so that a pressure surface 122 and a suction surface 123 are formed. And, as shown in (b) of FIG. 10, the inner blades 121B may be inclined in the other direction to the impeller 120 so that the pressing surface 122 and the suction surface 123 are formed. Here, being formed inclined in one direction means that each outer blade 121A is all inclined in one direction. And, being formed to be inclined in the other direction means that each inner blade (121B) is inclined in a direction different from the direction in which the outer blade (121A) is inclined. The reason why this should be is that the outer blades 121A are passively rotated by the water flow generated according to the operation of the submersible pump 10, but the inner blades 121B are actively rotated by the rotation of the impeller 120 . However, it is not essential that the inclination directions of the outer blade 121A and the inner blade 121B are different, but may be selectively determined as needed. For reference, a plurality of through holes 121C through which water flows may be formed between the outer blades 121A and the inner blades 121B.

As another embodiment, as shown in (a) of FIG. 11, the outer blades 121A are inclined in one direction on the impeller 120 so that the pressure surface 122 and the suction surface 123 are formed, and (b) of FIG. As such, the inner blades 121B may be inclined in one direction on the impeller 120 so that the pressing surface 122 and the suction surface 123 are formed.

In this way, the outer blades 121 are inclined in one direction on the impeller 120 so that the suction surface 123 and the pressure surface 124 are formed, and the inner blades are formed on the impeller 120 in one direction so that the suction surface and the pressure surface are formed. By forming it inclined, the flow of fluid from the bottom surface toward the submersible pump 10 is formed well, and the suction ability of the submersible pump 10 is improved.

The support 130 serves to support the impeller 120 on the bottom surface 150. As shown in FIGS. 4 and 11 , the support 130 may include a rotation connecting member 131E that rotatably connects the support 130 to the impeller 120 . Here, the rotation connecting member 131E may be implemented in various forms. For example, the rotation connecting member 131E may be implemented as a bearing. As another embodiment, the rotation connecting member 131E may be formed below the impeller 120 . In this way, by implementing the rotary connecting member 131E as a bearing, there is an advantage of minimizing frictional force generated when the rotary connecting member 131E is rotated.

The support 130 may include a flat portion 131A and one or more openings 131B formed in the flat portion 131A. Also, the support 130 may include one or more bolts 131C that are accommodated in the opening 131B and fix the support 130 to the bottom surface 150 through the flat portion 131A. Also, the support 130 may include a pillar portion 131D formed in a direction perpendicular to the flat surface of the flat portion 131A.

As described above, one end portion of the pillar portion 131D is rotatably connected to the impeller 120 through the rotation connecting member 131E, or the other end portion is rotatable toward the bottom surface 150 through the rotation connecting member. might be connected.

The pump suction guide device having a blade according to the present invention induces a good flow of fluid from the bottom surface toward the suction port of the submersible pump using an impeller, so that the operator must calculate and install the arrangement of the pump suction guide device one by one. There is no inconvenience, and even if the initial arrangement position is displaced to some extent, there is an effect that the suction capacity of the pump does not decrease according to use.

13 is a flowchart of a method of using a pump suction guide device having a blade according to the present invention.

Referring to FIG. 13, a pump suction guide device having a blade and a method of using the same according to the present invention include installing a pump suction guide device having a blade at the front end of an inlet of a submersible pump (S1), A step of sucking (S2) and rotating the impeller of the pump suction guide device having blades according to the sucking of the fluid (S3).

As a preliminary work for realizing a pump suction guide device having blades and a method of using the same, a pump suction guide device 140 having blades is installed at the front end of the inlet of the submersible pump 10. (S1)

In this state, when the submersible pump 10 is driven, fluid is sucked by the pumping operation of the submersible pump 10 (S2).

At this time, the impeller 120 of the pump suction guide device 140 having blades is rotated by the upward water flow formed according to the fluid suction operation of the submersible pump 10. (S3)

One or more outer blades 121 are formed on the outer surface of the impeller 120 or one or more inner blades are formed on the inner surface of the impeller 120 . The outer blades 121 and the inner blades rotate together as the impeller 120 rotates to improve the flow of fluid.

Accordingly, the flow of the fluid from the bottom surface toward the submersible pump 10 is formed well, so that the suction capacity of the submersible pump 10 is improved.

As another embodiment, one or more outer blades 121 may be formed on the outer surface of the impeller 120, and one or more inner blades may be formed on the inner surface of the impeller 120. Alternatively, inner blades may be formed only on the inner surface of the impeller 120 as needed.

In this case, since a water flow is formed on the outer surface of the impeller 120 and also on the inner surface, the suction capacity of the submersible pump 10 is further improved.

The outer blades 121 may be inclined at the impeller 120 so that the suction surface 123 and the pressure surface 124 are formed. The reason for doing this is to concentrate the water flow starting from the lower part of the impeller 120 to the inlet of the submersible pump 10 along the inclined surface. Here, the pressing surface 122 refers to an upper side surface relative to the outer blade 121A, and the suction surface 123 refers to a lower side surface.

In addition, the inner blades 121B may be inclined at the impeller 120 so that a suction surface and a pressure surface are formed.

The outer blades 121A are inclined in one direction on the impeller 120 so that the pressure surface 122 and the suction surface 123 are formed, and the inner blades 121B are formed on the impeller 120 so that the pressure surface and the suction surface are formed. It may be formed inclined in another direction.

A brush 124 is formed at the other end of the impeller 120, and the impeller 120 may be implemented in a shape in which the aperture gradually decreases from one end to the other end, as shown in FIG. Here, the other end means a lower end, and one end means an upper end. Then, the brush 124 rotates along the impeller 120 while being in close proximity to or lightly contacting the bottom surface.

Therefore, the brush 124 helps to float the floating matter remaining on the bottom surface in the water, and thereby has an effect of preventing the floating matter from remaining on the bottom surface.

The impeller 120 is coupled to the support 130 through a rotation connecting member 131E, and the rotation connecting member 131E may be implemented as a bearing. In this way, by implementing the rotary connecting member 131E as a bearing, it is possible to minimize frictional force generated when the rotary connecting member 131E is rotated.

The support 130 includes a flat portion 131A, and one or more openings 131B capable of receiving a bolt 131C serving to fix the support 130 may be formed in the flat portion 131A. there is.

A pillar portion 131D formed in a direction perpendicular to the flat surface of the flat portion 131A may be further formed on the support 130 .
