Description

PUMPING DEVICE

The present invention relates to, for example, a pump device included as part of a product or a water supply line of a factory.

Conventionally, pump devices have been used in various applications such as housing water supply, water supply in factories, installation in customer assembly products, and the like.

In particular, when it is included in factory water supply or customer assembly products, it is included in the piping. Therefore, when replacing the pump unit, it is required to have the same installation dimensions as those of the existing pump unit or equivalent external dimensions. Further, most of the pump apparatuses used for factory water supply are operated at a constant speed (fixed speed) at the maximum rotational speed in a commercial power source. Energy saving can be achieved by using a variable speed pump device that operates the variable speed pump according to the demanded quantity (amount of water). However, in order to use a variable speed pump device, it is necessary to install a control panel including an inverter.

For example, according to the following Patent Document 1, a pump device which can be attached without changing the facility piping and is controlled at a variable speed such as a pressure constant control is known. 1 of Patent Document 1, in a pump device which is provided in a pump casing and has a pump portion having an impeller and a motor portion for rotationally driving the impeller 11, the pump portion receives a signal from the pressure sensor and operates the pump portion at a variable speed And the control unit is disposed outside the motor unit.

As an electric motor, according to Patent Document 2, there is known an electric motor having an integrated control device structure in an output model of a medium or more capacity. Fig. 1 of the reference 2 discloses a configuration in which the control unit case of the controller unit is divided into a plurality of unit cases, and the unit case is overlapped and fixed to the anti-load side end bracket or the housing.

Japanese Patent Application Laid-Open No. 2009-41500 Japanese Patent Application Laid-Open No. 11-27903

However, in the technique described in Patent Document 1, the existing pump apparatus, which is compatible with the piping installation dimensions but has a larger size by the minute that the control unit is attached to the outside of the motor unit and has installed the control panel separately, There is no compatibility. Further, in an environment in which the installation space is narrow or the installation conditions such as the inside of the product are severe, it is impossible to exchange with the existing pump apparatus.

In addition, when the pump device is included in the factory water supply or customer assembly product, it is included in the middle of the piping. Therefore, when the center of gravity of the pump device is biased, a load is applied to the piping. Further, at the time of replacement of the pump device, the pump device is temporarily placed temporarily, and it is required that the pump device can be stably self-sustained.

In the technique described in Patent Document 1, the center of gravity is shifted by an amount corresponding to a portion of the control portion attached to the outside of the motor portion. If the weight of the pump part and the rotating electric part is sufficiently larger than that of the control part, the self-sustaining device can be self-supporting, but since the control part has a considerable weight for the pump part and the rotating electric part, Is not considered.

In the electric motor described in Patent Document 2, power switching devices (for example, IGBTs) constituting the inverter are large in heat generation among various components mounted together with the rotary electric main body, particularly, in the electric power conversion device. Therefore, as disclosed in Patent Document 2, in the case where the motor is mounted in a cylindrical case which is placed on one end of the rotating electric machine so as to overlap on the rotating shaft, the electric power of the inverter It was difficult to reliably discharge the heat to the outside.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances and it is an object of the present invention to provide an apparatus and a method for controlling the same, Which is a space-saving driving unit control device integrated with a pump device. It is also an object of the present invention to provide a pump apparatus capable of attaching without imposing a load on a piping or a product structure of the apparatus and performing variable speed operation control such as pressure constant control by a single pump apparatus.

Further, the existing pump device is provided with a pump device , It is possible to make it equal to or less than the external dimensions of the pump portion. It is possible to replace the pump unit with the drive unit control unit without affecting the water pipe or the product.

Fig. 2 shows a cross-sectional view of the pump device. A casing cover or an end bracket integrally formed with an end bracket considering a flow of air flows between a plurality of cooling fins formed on the outer circumferential surface of the housing via a cover to be blown from the outside by rotating the centrifugal fan to be described later have. The rotary electric main body is accommodated in the cover 10, and the rotary shaft (shaft) 56 of the rotary electric machine is connected to rotate the impeller disposed in the pump casing. The rotational axis of the impeller in the pump section and the rotational axis of the rotational electric section coincide with each other.

Fig. 3 shows the overall structure of the rotary electric power assembly used in Figs. 1 and 2. Fig. That is, in this drawing, reference numeral 10 denotes a cover which covers the outer periphery of the rotary electric main body, and has a substantially cylindrical outer shape. The cover 10 is formed in a predetermined shape by, for example, press working, etc., in a plate-shaped resonance suppressing material. More specifically, by attaching a sound absorbing material, a sound insulating material, a damping material, a vibration absorbing material, or the like to the inside of the cover, noise and vibration can be suppressed.

A cooling cover 20 incorporating a centrifugal fan 21, which will be described later, is attached to one end portion (inside the drawing) in the axial direction of the cylindrical cover 10, and the other end portion The end bracket 11 of the rotary electric machine described below is attached. In addition, on the outer circumferential surface of the cylindrical cover 10, a case (power conversion device case) 30 housing a power conversion device to be described later, and a terminal box (a noise box built- ) 40 are attached, respectively.

4, the overall structure of the rotating electric part 50 housed in the cover 10 is shown as an exploded view. In this drawing, reference numeral 51 denotes a so-called substantially cylindrical housing (also referred to as a " frame "). The housing 51 is made of, for example, a thermally conductive And is formed by extruding a material such as aluminum. As shown in the figure, the housing 51 also has a plurality of cooling fins 52L and 52S extending in parallel along the cylindrical rotation axis on the entire outer peripheral surface thereof. A flat surface 53 having a relatively large area for attaching the above-described power conversion apparatus (that is, the power conversion apparatus case) 30 is provided on a part of the outer circumferential surface of the housing 51 And a relatively large (elongated extension) cooling fin 52L is formed in the periphery of the cooling fin 52L in the horizontal direction.

An armature constituting a stator (stator) 54 of the permanent magnet type rotary electric machine is inserted and fixed in the cylindrical housing 51, and the inside of the cylindrical internal space of the armature 54 (Rotor) 55 constituted by arranging a plurality of permanent magnets in a cylindrical shape is inserted and is rotatably attached through a predetermined gap. Reference numeral 56 in the drawing denotes a rotary shaft (shaft) formed integrally with the rotor (rotor) 55, and is configured to rotate the rotational driving force of the rotary electric machine through the shaft, for example, To the driven equipment. Reference numeral 57 in the drawing denotes an end bracket attached to the end of the housing 51 on the side opposite to the end bracket 11 described above and reference numeral 58 in the figure indicates a cross- (Shaft) 56 on the outside of the rotary shaft 57 as shown in Fig.

5 shows the parts when the rotating electric machine 50 described above is housed inside the cover 10 shown in Fig. 3, as a developed view. That is, in the rotating electrical machine 50, a part of the outer circumferential surface of the housing 51, for example, in the example shown in the figure, the portion where the relatively short cooling fins 52 are formed, The control and I / F substrate case 60 and the smoothing capacitor case 70 formed in a substantially circular arc shape are attached (or fixed) and then inserted into the cover 10 ). A power switching element (for example, an IGBT or the like) which is a heating element constituting the inverter is partially provided in the plane 53 of the housing 51 through an opening 511 provided in a part of the cover 10 A power conversion device 31 is attached to a plane 53 formed on a part of the housing 51 of the rotary electric machine 50 and thereafter a cover (See arrows in the drawing). The above-described terminal box (terminal box with built-in noise filter) 40 is attached to a part of the outer peripheral surface of the housing 51 (see arrows in the drawing). The above-described cooling cover 20 is attached to the other end (left end in the drawing) of the housing 51. Reference numeral 21 in the drawing denotes a plurality of small holes formed in a substantially central portion of the wall surface of the cooling cover 20 so as to blow out the outside air.

In other words, according to the rotary electric assembly including the rotary electric main body and the peripheral device described above, the centrifugal fan 58 attached to the front end thereof is rotated by the rotary shaft (shaft) 56 rotating with the operation of the rotary electric machine The air from the outside is guided to the inside of the cover 10 and flows between the plurality of cooling fins 52 formed on the outer peripheral surface of the housing 51 to perform heat exchange (see the white arrow in Fig. 4) , And thereafter flows out to the outside through a gap between the end bracket 11 and the other end. That is, the airflow generated by the rotation of the centrifugal fan 58 cools the housing 51, on which a plurality of cooling fins 52 are formed.

As described above, the power conversion device 31 includes a power switching element, which is a heating element, in order to configure the inverter, so that the amount of heat generated is large. However, according to the present invention, as described above, the power inverter 31 is provided with a part of the housing 51 integrally provided on the outer periphery of the stator (stator) 54 for discharging the heat of the rotating electric machine to the outside, That is, directly attached to the flat portion 53 for attachment. According to this, the heat generated by the power inverter 31 is transmitted to the housing 51 along with the heat generated by the rotating electric machine (particularly, the heat generated by the armature) The cooling fins 52 formed so as to be arranged in parallel with each other by the material excellent in heat resistance are efficiently transmitted to the outside air. That is, it is possible to efficiently discharge the heat generated by the power conversion device 31 to the outside, together with the generation of the rotating electric power, thus achieving a good cooling effect of the power conversion device.

Particularly, in the above-described embodiment, the periphery of the attaching plane 53 formed on the upper portion of the cylindrical housing 51 in which the power inverter 31 is disposed is provided with a relatively large Since the fin 52 is formed, it is possible to efficiently cool the heat generated by the rotary electric machine 31 as well as the heat generated by the rotary electric machine.

As described above, according to the present invention, the control & I / F substrate case 60 and the capacitor case 70 are also attached (fixed) to a part of the outer peripheral surface of the housing 51, The heat generated inside these cases can be efficiently discharged to the outside through the cooling fins 52 formed on the outer periphery of the housing 51 as described above.

This control & I / F board case 60 is a board for a control & I / F board, in which an I / F board for communication is built in, together with a control controller (for example, a control microcomputer) Which is excellent in environmental resistance and impact resistance. By attaching the control & I / F board case 60 to a part of the rotary electric machine, it is possible to perform the communication control with the outside by wireless / wired as well as drive control of the outdoor installation pump. According to this, by mounting a pressure sensor, a flow rate sensor, or the like on the control & I / F substrate, it is possible to automatically control the amount by using these amounts as a feedback signal, Communication), centralized management and an integrated energy saving monitor system can be realized. In other words, the operation management of the outdoor installation pump, the energy saving operation, and the like become possible, and remote monitoring control, centralized management, or systemization by a plurality of pumps can be realized as described later.

The condenser case 70 is a housing in which a smoothing capacitor constituting a part (component) of the inverter circuit of the power inverter 31 is accommodated. In the same manner as described above, a resin material or the like By injecting, environmental resistance and impact resistance are promoted. Although the DC reactor constituting a part of the inverter has been described as being included in a part of the power conversion device 31 in this example, the DC reactor is also built in the special case, Or may be attached to a part of the outer circumferential surface.

In addition, in the present invention, instead of the above-described embodiment, as shown in Fig. 6, for example, the heat generating portion (mesh portion) H in the power inverter 31 may be formed in a cylindrical shape On the flat surface portion 53 of the housing 51 and away from the central portion of the stator (armature) 54 (indicated by the broken line B in the figure), which is the heat generating portion of the rotating electrical machine, So as to be positioned close to the centrifugal fan 21 side built in the cooling cover 20. According to this, since the heat generating portion is dispersed without concentrating, efficient cooling becomes possible.

7, a portion of the outer periphery thereof, particularly, a portion near the flat portion of the housing 51 to which the above-described power conversion device 30 is attached is cut off (cut) (541)), so-called cut cores may be employed. According to this, by separating the power conversion device 30 and the stator (armature) 54, which are the heat generating portion, at the cut portions, the absorption of heat by the housing 51 can be separately separated and efficiently cooled.

As described above, according to the pump apparatus of the present invention, the housing in which the cooling fin is formed on the outer periphery is directly used as the cooling portion of the heat generating component such as the inverter, And a circuit board, or a noise filter or a condenser. That is, in the present invention, by adopting the permanent magnet motor, the dimension of the motor can be made smaller than the dimension of the induction motor. By arranging the components such as the power conversion measures and the control board on the periphery of the housing as described above, the external dimensions of the pump device having the same output performance and the induction motor having the separate control panel It is possible to provide a pump device which is capable of supplying a high- In other words, it is possible to replace the conventional pump device equipped with the induction motor, and a control panel is not required, thereby realizing a considerable space saving.

In addition to the external dimensions, it is possible to provide a pump device that can achieve a high heat radiation effect and can also be driven practically by employing the above-mentioned heat dissipation structure for heat dissipation which has been a conventional problem.

In the present invention, since the drive unit control device integrated pump device having the above-described characteristics, there is no need to separately install a control panel, and a plurality of pump devices can be used for a portable terminal, The control can be performed simply.

Next, Fig. 8 shows an overall configuration of a longitudinal-type direct-acting pump, for example, as an outdoor installation pump apparatus, which is another embodiment of the present invention. As the rotary electric machine assembly to be used, the same rotary elements as those described in Figs. 3 to 7 are used.

In this drawing, reference numeral 1 denotes a pump casing, and reference numeral 10 denotes a cover which covers the outer periphery of the rotary electric assembly. Reference numeral 20 denotes a cooling cover. Reference numeral 30 denotes a case housing the power conversion device, and reference numeral 40 denotes a noise filter built-in terminal box.

Fig. 9 shows a cross-sectional view of the pump device. As described later, as the centrifugal fan rotates, air is blown from the outside, and a plurality of cooling fins formed on the outer circumferential surface of the housing through the cover flows through the cover and flows out to the outside through a gap between the cooling fin and the end bracket. Considering the flow, a casing cover indicated by reference numeral 2 is attached.

In addition, the rotary electric main body is accommodated in the cover 10, and the rotating shaft (shaft) 56 of the rotary electric machine is connected to rotate the impeller disposed in the pump casing. The rotational axis of the impeller in the pump section coincides with the rotational axis of the rotating electrical section, and when the pump is used, the rotational axis is perpendicular to the pump mounting surface.

Next, balance and self-sustaining stability of the pump apparatus of the present embodiment will be described with reference to the schematic diagrams of Figs. 10 to 14. Fig.

10 is an explanatory diagram (schematic diagram) of the position of the center of gravity when the power conversion apparatus including the inverter is installed in a pump apparatus in which a conventional rotary electric assembly (motor unit) is integrated. In Fig. 10, the power conversion device is collectively disposed on the outside of the motor portion integrated with the pump portion. In this case, the weight of the power conversion apparatus is large, and the position of the center of gravity in which the power conversion apparatus and the motor unit are combined is largely deviated from the rotation axis of the rotating electric machine (motor) as shown in the lower portion of Fig.

In such a state, even if the entire pump apparatus is slightly inclined as shown in Fig. 11, since the position of the center of gravity is located at a position deviated from the rotation axis of the motor unit, it soon collapses and the balance and self- . If such a pump device is included in the middle of the piping, it can be understood that a large load is applied to the other piping portion.

Fig. 12 is an explanatory diagram (schematic diagram) showing the center of gravity of the pump apparatus of the present invention. In the present invention, unlike FIG. 10, the power conversion device, the control board, and the smoothing capacitor are disposed so as to be at least partly housed inside the cover of the rotary electric assembly.

Specifically, as shown in Fig. 5, the power conversion device 31 is disposed on the upper portion of the housing 51, and the capacitor case 70 is disposed inside the lower portion of the housing 51, (60) is disposed in front of the lower portion of the housing (51). Each member is about 120 DEG centered on the rotational axis of the rotating electrical machine.

Considering that the weight of the power conversion device 31 and the smoothing capacitor is greater than the weight of the control & I / F substrate 60 in the present invention, at least the power conversion device and the smoothing capacitor are separated from the rotation axis of the rotating electric machine Position (for example, 120 DEG to 180 DEG).

On the other hand, since the noise filter is relatively small in weight relative to the power converter, the noise filter case 40 is disposed outside the cover 10, The impact is small.

Accordingly, as shown in the lower part of Fig. 12, the center of gravity of the motor unit and the combined power converter, control board, condenser, and pump unit is close to the rotation axis of the motor unit.

As shown in Fig. 13, in the pump apparatus of the present invention, since the center of gravity of the pump is located in the vicinity of the rotation axis of the motor unit, the pump does not collapse to some extent, and balance and independence stability can be ensured. Accordingly, when the pump apparatus of the present invention is installed in the middle of the piping, it is possible to stably install the piping and other parts without applying a large load. Further, also in the installation work, the pump apparatus of the present invention is excellent in self-supporting property, so that damage to the pump apparatus or other members due to collapse of the pump can be prevented, and the workability is excellent.

14 shows a region of the center of gravity at a preferable position as the whole pump apparatus. Since the position of the center of gravity is less likely to collapse as it is closer to the center axis, the position of the center of gravity should be near the center axis. Particularly, it can be said that the rotational axis of the impeller and the rotational axis of the rotating electrical unit in the pump unit are coincident with each other, and it is preferable to be within a range of 1/2 of the diameter of the motor unit around the rotational axis of the motor unit and the pump unit.

Further, as shown in the hatched portion in Fig. 14, the center of gravity of the upper bottom surface of the cylindrical portion of the housing of the motor portion becomes the apex of the lower center of gravity of the lower portion of the motor portion, It is preferable to make the inside of the cone defined by the circle of circle 2. In this case, the diameter of the motor section means the maximum diameter of the motor section covered with the cover.

In the above embodiment, the rotary electric power unit for driving the outdoor installation pump is constituted by the permanent magnet rotary electric machine. However, the present invention is not limited to this, and the rotary electric machine for other purposes And it will be clear to those skilled in the art that the same effect can be obtained thereby. In the above embodiment, the cover 10 is formed so as to extend so as to substantially cover the entire rotating electric part 50. However, the present invention is not limited to this, and for example, And the cover 10 may be set to about half of the longitudinal direction of the rotating electric part 50. In this case as well, the same effect as described above can be obtained.

The control of the drive unit control device integral pump device taking advantage of the above features will be described with reference to Figs. 15 to 17. Fig.

15 is a flowchart of a control method when a plurality of pumps of the same kind are used. During the stop of the pump 101, it is determined that the pump needs to be started in the case where the amount of water (water amount) exceeds the predetermined reference or the pressure is lower than the predetermined reference (102), and the pump is started up 103). On the other hand, in the case where the water quantity is reduced (104), since the pump does not need to be started, the pump stop state continues (101).

In the case where the pump 1 is in operation (201), it is determined that a new pump needs to be started at 202 when the quantity exceeds the predetermined reference or the pressure falls below the predetermined reference, (203). On the other hand, if the water quantity is reduced (204), since the pump does not need to be started, stopping the pump 1 is stopped (205).

Also, in the case where the two pumps are in operation (301), it is determined that a new pump is required to be started at a time when the water quantity exceeds the predetermined reference or the pressure falls below the predetermined reference (302) (303). On the other hand, when the water quantity is reduced (304), the stop of the pump 1 is stopped (305). Control is also performed for three units or more by the above-described flow.

As shown in Fig. 16, the above-described control of the pump is performed with respect to a plurality of drive unit control unit integral type pump units from a pump market or a master unit of a pump apparatus of the same kind.

For each pump device, confirmation of the current state, an instruction to start the operation, an instruction to stop the operation, and the like are sent from the pump market or the master device of the same kind of pump device. This instruction is performed by a wireless communication or a control signal line (wired) such as a wireless LAN or Bluetooth (registered trademark) built in for the control & I / F board of the pump device.

In communication, an identification number is assigned to each pump device. The control board of the pump apparatus is provided with a storage section and has an area for storing an identification number unique to the pump apparatus. A randomly generated number other than a predetermined number (for example, 0000 to 0099) is set as an identification number, and data is transmitted according to a predetermined communication format. The data is transmitted to the pump device from the pump market or the master device of the same kind of pump device, but if there is no reply, the communication is resumed after the time determined at random. When there is a reply, the identification number (for example, 0000 to 0099) specified in the reply data is used as the identification number of the pump device. In order to prevent communication conflicts, the pump apparatuses to which 0000 to 0099 are allocated are not allowed to communicate for a certain period of time so as to perform communication other than 0000 to 0099 after each communication.

When the pump device fails, the effect of the fault is communicated to the pump device side by communication. If there is a failed pump device, stop the pump device and start another pump device.

In addition, the monitoring device and the pump device for monitoring the pump device can be operated in the same manner as in the case where the operation status of the other pump (the details of the failure in the case of failure) and the breakdown history, the number of the same kind of pump device, A logarithm number, the number of pump apparatuses currently operating, and the number of pump apparatuses that have failed. By outputting the information to the portable terminal, it is possible to grasp the situation (overall situation) of all the pump devices by communicating with one monitoring device or pump device.

Further, when the control board of the pump apparatus has a position information detecting apparatus (for example, a GPS apparatus), the mounting position of the pump apparatus can be grasped, and a plurality of pump apparatuses can be grouped and controlled for each position of the pump apparatus .

17 is a block diagram showing the connection relationship of a plurality of pump devices. 17, reference numerals 1-1, 1-4, 2-1, 2-4, 3-1 and 3-4 denote gate valves, 1-2 denote pump units 1, 2-2 denote pump units 2, 1-3, 2-3 and 3-3 are check valves, 1-5 are the first motor section, 2-5 are the second motor section, and 3-5 are the third, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, , Reference numeral 3-7 denotes a control board 3, reference numeral 1-8 denotes a wireless interface, reference numeral 2 denotes a wireless interface, reference numeral 2 denotes a wireless interface, and reference numeral 3 denotes a wireless interface.

For example, when data (data items and data contents) to be set are transmitted from a portable terminal (not shown), the pump control is performed through the air interfaces 1-8, 2-8, 3-8 of the pump apparatus Data is written in a storage unit for storing data. In this case, the identification number of the pump is sent together with the data to clarify the object to which the data is to be transmitted. The wireless interface and the storage unit are included in the control & I / F board 1-8, 2-8, 3-8 of the pump apparatus.

It is preferable that the portable terminal includes a display device, and the display on the portable terminal is not a data content itself but a conversion (for example, 0? Pump stop, 1? Pump operation, etc.) Display. In the portable terminal, for example, when an error code indicating an error code is displayed, even when an operation status or a fault detail is acquired, the contents indicated by the error code are displayed (for example, if the error code " E1 "Quot; overcurrent ").

Next, when a command to acquire the driving situation is given from the portable terminal, the driving condition data is stored in the storage section for storing the pump operation data through the air interfaces 1-8, 2-8, 3-8 of the pump apparatus And the read data is sent to the portable terminal through the wireless interface.

Further, when the pump is operated from the portable terminal, it is possible to set a frequency (motor revolution number) for giving an operation / stop command or operating such as setting of data. When the data item related to the operation state of the pump device is designated instead of the " command " of the operation / stoppage, the operation is set to " operation "Quot; can be set.

As shown in Fig. 17, when there are three or more pumping apparatuses, priority is given to the pumping apparatus in advance, and the pump apparatus having the highest priority can be used as the master pumping apparatus.
