DESCRIPTION

A PUMPING DEVICE THAT PROVIDES LINEAR CURRENT Technical Area

The current invention is related to a pumping device ensuring that the fluid materials such as water and liquid are transmitted from one area to another area.

The invention comprises a pumping device that has an outer flexible pipe forming an enclosed volume between the first suction area (A) and destination area (B) which has a flexible shaft through which the rotational motion from pumping device is transferred and which has at least one impeller to which rotational motion is transferred through this flexible shaft, and that has multiple centering components ensuring that said flexible shaft is centered and/or beared inside the outer flexible pipe. Background of Invention

In general, the pumps are described as machines ensuring that the liquids are transmitted from one point to another point. To this end, the liquids can be transmitted in diverse manners: through a reciprocating piston (piston pump), with a rapidly rotating shovel wheel (centrifugal pump), by spraying pressure water (water spraying pumps, hydraulic pressure pumps), and by spraying pressure vapor or pressure air (injector). In the piston pumps, water is transferred with a reciprocating piston inside a cylinder, thus, water can be carried intermittently only. To do that, it is needed to provide valves which open and close the suction and force equipment at intervals. To prevent intermittent movements of water inside pipes, it is pressed to air boiler before delivering to the equipment pipes; and then it is continuously fed to the equipment pipes under pressure which is somewhat not changed. For the centrifugal pumps things are different. Here it is not needed to provide valves and air boiler as water is transferred by shooting through a wheel with shovels thereon. For the hydraulic pressure pumps, also valves and a pressure air boiler are used. Similarly the pressure air pumps operate uninterruptedly and without valve, while the pressure vapor pumps operate intermittently and with valves.

The mostly used pump types are piston and centrifugal pumps. Today, the usage area of the centrifugal pumps is broader than the piston pumps. Also, although the revolutions of the piston pumps are higher than the centrifugal pumps, the centrifugal pumps need high speed machines to get driven since they operate at high speeds.

In other words, we can define the piston pumps as follows: components activating the liquid in static state and pressing to system under a specified pressure and a flow rate. Pumps receive their rotational movements with couplings from an electrical motor according to the required power, and in this way, the electrical energy is converted to the mechanical energy and the mechanical energy to the hydraulic energy. Pumps can be classified according to their intended use, materials manufactured, liquids they pumped and their shapes.

In the patent researches made concerning the pumps, some applications have been found out; among such applications, there is a utility model application numbered TR 2009 00165U dated 09.01.2009. In the summary page of this application; the invention is related to at least one electrical motor, one main switch, one pump suction line, one pump main pressure line, liquid transfer pumps having at least one pump pressure line main valve purposing to transmit any liquid, and it covers minimum one vacuum pump conducting first suction over a driving device that starts rotating in line with operation of the said electrical motor, and at least one main pump which ensures the liquid to be transferred is transmitted by pumping and which is situated on the same driving device with the said vacuum pump.

Another application is the one made for the utility model numbered TR 2009 03827U and dated 18.05.2009. As stated in the summary page of this application; our invention has been made on the purpose to add to the centrifugal pumps which are transmitting water from one point to the other by generating an artificial G force depending on revolution. Yet, it is not faced with a problem between the motor and the centrifugal system including our invention and the extreme point of the system from which suction is made even the system is open to outside, and suction is continued. Hereunder, thanks to the transmitting impeller placed immediately behind the outer strainer at the extreme point and to the motion transfer system coupled to motor and centrifuge, it is driven to transmit the liquid from extreme point to the wheel of motor and centrifuge.

Depending on distance, it takes 3 to 10 seconds that the liquid reaches the motor and centrifuge from the extreme point, which eliminates any air accumulation occurring in the centrifuge systems. Furthermore, thanks to our invention, any possible distance restriction in the centrifugal systems is eliminated and no flow rate loss occurs at the said intervals.

In the current technique, there are different pump mechanisms to provide liquid transfer between specified points. For such operations, the pipes prepared in the standard lengths such as 3 to 6 meters and pump equipment complying with these pipe lengths/diameters are used. In some cases, this type of pump lines fails to satisfy. Such insufficient facilities, particularly shortages such as not presence of a straight line among points where the liquid transfer shall be made, need for implementing zig zag transmission, providing liquid transfer line over standard heights constitute significant obstacles for the current pump systems. Particularly, a straight transfer line could not be available on boards of vessels or in similar places. In the long suction lines, suction can not be achieved as the single point suction system is not capable to provide sufficient vacuum. Thus, there are several developments to lay out pipes curled and in spite to be able to implement liquid transfer.

Description of Invention

The objective of the invention is that no vibration occurs because no impact takes place due to physical feature of turbine blades when the air sucks and forces the liquid fluids. Additionally, it has a strong horizontal - G - passage when it provides linear flow. Thanks to this feature, it has a flow rate parallel to revolution. The invention does not lead to any air bubbling when it sucks and forces the fluids. For this reason, no loss of flow rate and pressure take place. The system is composed of a half submerged pump partly. It is a pump which is operated based on the method of remote converted free flow, and this system can be operated by applying two cycles. An objective of the invention is to provide a suction impeller added to the suction end of the pipe line through which suction is made to ensure the vacuum capability in case of extension of pipe line.

An objective of the invention is to attain flow rate depending on revolution. The operation logic is that the rotational motion from motor reaches the pump and the suction source (impeller) and thus, suction happens with more pressure and flow rate.

Another objective of the invention is that the developed turbine pump has neither air accumulation nor vibration. No vibration occurs because no impact takes place due to physical feature of turbine blades of the end impeller. Air accumulation is prevented as the suction is stronger thanks to jet pump.

A further objective of the invention is that there are no mechanical failures among bearing pipes such as jamming and contracting under no circumstances, because some flexible and extending/contracting mechanisms have been used among the bearing pipes.

Another objective of the invention is that this pump can be used in an optimal working range of 9 mt to 90 mt horizontally and vertically. The invention can be coupled to the conventional pumps which lead to air accumulation and have no suction force remotely, in order to serve as a feeding unit. A further objective is that there is a filter on the first suction nozzle where water is sucked. This filter is used to clean and separate the materials, wastes and contaminants carried by the material to be sucked. The kinetic energy of water entering into the impeller is increased by energizing through turbine.

Another objective of the invention is that the time elapsing to reach the vertical peak of water inside a hose, 9 mt long, with a diameter of 100 mm is 3 seconds and the utilized power is 0.25hp. These results were obtained by the lab tests. It is observed that thanks to this features the pump system can be operated without having impacted by any and all flexibility horizontally and vertically.

To achieve the aforementioned objectives, it comprises a pumping device that has an outer flexible pipe forming an enclosed volume between the first suction area (A) and destination area (B) which has a flexible shaft through which the rotational motion from pumping device is transferred and which has at least one impeller to which rotational motion is transferred through this flexible shaft, and that has multiple centering components ensuring that said flexible shaft is centered and/or beared inside the outer flexible pipe.

Detailed Description of Invention

The current invention is related to a pumping device (10) having a motor (11) and pump (12) to ensure that the fluid materials such as water and liquid are transmitted from one area to another area, and it comprises an outer flexible pipe (44) forming an enclosed volume between the first suction area (A) and destination area (B), which has a flexible shaft (28) through which the rotational motion from the said pumping device (10) is transferred and at least one impeller (33) to which rotational motion is transferred through this flexible shaft (28).

Also, it contains multiple centering components (35) ensuring that said flexible shaft (28) is centered and/or beared inside the outer flexible pipe (44), multiple centering blades (36) of the said centering component (35), the single housing prominent clamp (20) transferring the rotational motion received from pump/motor group (10) to the flexible shaft (28), said single housing prominent clamp (20), and the connection protrusion (21) made on the one end and the connection recess (22) made on the other end, at least one casing component (41) clutching the said single housing prominent clamp (20) and the flexible shaft (28) from outside and ensuring that they can be bedded, and a bedded ball bearing (23) between the said casing component (41) and single housing prominent clamp (20). It further comprises multiple outer covers (24) having a cover extensity (25) and located between the said outer flexible pipes (44), a two sided female clamp (42) serving as a connection between a single housing prominent clamp (20) in the intermediate connections and the flexible shaft (28), the connection housings (43) made in both directions of the said two sided female clamp (42), the bearing components (26) positioned between the said two sided female clamp (42) and single housing prominent clamps (20) and centering components (35), the clamp holders (29) ensuring the said flexible shaft (28) is bedded between the bearing components (26), minimum one shaft bearing (30) bearing the said flexible shaft (28) and the spiral casing enclosing this shaft bearing (30), a filter cartridge (32) positioned on the said first suction area (A), an impeller shaft (37) connecting the said impeller (33) and flexible shaft (28), a felt (34) positioned between the said impeller shaft (37) and centering component (35), segments (38) and ball bearings (39), and a minimum alien housing (27) positioned among the said impeller shaft (37), connection protrusion (40) and the said two sided female clamp (42) and single housing prominent clamp (20).

The operation mode of pumping device (10) is as follows; in figure 1 and 2, the complete perspective views of the device are illustrated. The outer flexible pipe (44) can be comfortably used in all angles and curled shapes thanks to its flexible structure (see figure 2). In the first suction phase, it is prevented that the particles, residues and wastes together with water are entered through a filter cartridge (32) placed on the first suction area (A) of the pumping device (10). In the other figures, the internal mechanical structure of the device is illustrated.

As it may be understood from the figures, the flexible shaft (28) which is exercised to start with rotational motion with drive from motor (11) and pump (12) assembly takes its first motion from the connection recess (22) and single housing clamp (20) with which it is connected. The one end of clamp (20), namely the connection protrusion (21 ) is associated with pump (12). As a result of having exercised the flexible shaft (28) to make rotational motion, this motion is transferred to the impeller (33) which is positioned in the first suction area (A). Many intermediate members are used when transferring the rotational motion of the flexible shaft (28) to the impeller (33). For the intermediate connections, the single housing prominent clamps (20) and the two sided female clamps (42) are used. The rotational motion of the impeller (33) is obtained by the impeller shaft (37) and the two sided female clamp (42) connected with this shaft (37). The flexible shaft (28) used in the system is operated with highly low frictional losses. The outer flexible pipes used for the device (44) can be 3 to 6 mt long; when mounting this system to the pipes (44), there are ball bearings (23, 29), clamps (20, 42) and bearing components which are centering and fixing the device on one side. Thanks to the clamps (20,42) and to the recesses and housings (22, 43) made on these clamps, the extensions and contractions arising when the outer flexible pipe (44) is used flexibly in horizontal and vertical motions are provided. Otherwise, jamming and contracting of system may occur which leads to power loss. As known, the flexible shaft (28) transfers driving from motor (11) assembly to the impeller (33). However, as an alternative to the flexible shaft (28), it is possible to use a very little and x-proof electrical motor (45) behind turbine which can be operated in water. For example; the conventional centrifuge eliminates the suction based air accumulation problem when we couple the outlet side of this pump with the inlet of the centrifuge. Further, the problem of suction from depth and remotely is eliminated when it is coupled with the centrifugal pump as this system pumps directly from the source at 9 to 90 mt distance horizontally and vertically. If the system is coupled with the centrifugal pumps or other pumps, it feeds the fluid to the unit pressurizing it to the pump and thus it can be used for all pumping systems requiring this action. Through the pumping device (10) which is the subject matter of the invention, the time for reaching of water inside a pipe (44), 9 mt long, 100 mm diameter, to the vertical peak is 3 seconds. The power utilized is 0.25hp. Thanks to these features, the pumping device (10) can be operated without having affected by all flexions, regardless vertical or horizontal, (see figure 2)ยท

In figure 6; the section where the impeller (33) is exercised to start with rotational motion and suction is made from the main source. In this section pressure and flow rate are increased. The fluid to be sucked is firstly passed through filter. The filter cleans materials, wastes and contaminants coming with the material to be sucked. The kinetic energy of water entering into the impeller (33) is increased by energizing through turbine. One of the most important features of the pumping device is that it does not cause any air accumulation and vibration. Due to the physical structure of the turbine vanes, the impeller (33) does not impact the fluid resulting in no vibration occurs. Since suction is also highly strong thanks to the impeller (33), no air accumulation occurs.
