Description

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

Conventionally, pump devices have been used for various purposes such as residential water supply, factory water supply, and incorporation into customer assembly products.

Above all, since it is installed in the middle of piping when it is installed in factory water supply or customer assembly products, when replacing the pump device, it is required to have the same mounting dimensions or the same outer dimensions as the existing pump device. Furthermore, most of the pump devices used for factory water supply are operated with a commercial power supply at a fixed maximum speed. Energy saving can be achieved by using a variable speed pump device that operates the pump at a variable speed according to the amount of water demand, but installation of a control panel including an inverter is required to obtain a variable speed pump device.

For example, according to the following Patent Document 1, there is known a pump device that can be installed without changing the equipment piping and is variable speed operation control such as constant pressure control. Figure 1 of Cited Reference 1
In the pump device in which the pump unit provided in the pump casing and having the impeller and the motor unit for rotationally driving the impeller 11 are integrated, the pump unit is operated at a variable speed in response to a signal from the pressure sensor. The control unit is arranged outside the motor unit.

Further, as an electric motor, according to Patent Document 2, an electric motor having a control device integrated structure in an output model having a medium capacity or higher is known. FIG. 1 of the cited document 2 discloses a configuration in which the control device case of the controller unit is divided into a plurality of unit cases, and the unit cases are stacked and fixed to the non-load-side end bracket or the housing.

However, in the technique described in Patent Document 1, although the pipe mounting dimensions are compatible, the dimensions are increased by the amount that the control unit is mounted on the outside of the motor unit, and the existing pump in which the control panel is installed separately. The external dimensions are not compatible with the device. In addition, it is impossible to replace the existing pump device in an environment where the installation conditions are severe, such as a small installation space or built in the product.

In the electric motor described in Patent Document 2, among various components mounted together with the rotating electrical machine main body,

Therefore, as disclosed in Patent Document 2 above, when mounted in one end of a rotating electrical machine inside a cylindrical case that is stacked on the rotating shaft, the inverter (ie, its power) It was difficult to reliably dissipate the heat generated by the switching element) to the outside.

The present invention has been made in view of the above circumstances, and can be mounted without changing the equipment piping and product structure while reliably performing heat dissipation, and variable speed operation control such as constant pressure control can be performed by a single pump device. It is an object of the present invention to provide a space-saving drive unit control device-integrated pump device that can be carried out in

Or, an end bracket is provided. The rotating electrical machine main body is housed inside the cover 10, and a rotating shaft (shaft) 56 of the rotating electrical machine is connected to rotate an impeller disposed in the pump casing. The rotating shaft of the impeller in the pump unit and the rotating shaft of the rotating electrical machine unit coincide.

FIG. 3 shows the overall configuration of the rotating electrical machine assembly used in FIGS.
That is, in this figure, the code | symbol 10 has shown the cover which covers the outer periphery of a rotary electric machine main body, and is provided with the substantially cylindrical external shape. The cover 10 is formed into a predetermined shape by, for example, pressing a plate-shaped resonance suppression material. More specifically, noise and vibration can be suppressed by attaching a sound absorbing material, a soundproofing material, a vibration damping material, a vibration damping material, or the like inside the cover.

A cooling cover 20 containing a centrifugal fan 21 to be described later is attached to one end portion (back side in the drawing) of the cylindrical cover 10 in the axial direction, and the other end portion (front side in the drawing). ) Is attached with an end bracket 11 of a rotating electrical machine described below. Furthermore,
On the outer peripheral surface of the cylindrical cover 10, a case (power conversion device case) 30 containing a power conversion device, which will be described later, and a terminal box (noise filter built-in terminal box) 40 incorporating a noise filter therein. Are attached.

Subsequently, in FIG. 4, the entire structure of the rotating electrical machine portion 50 incorporated in the cover 10 is shown as an exploded view. In this figure, reference numeral 51 denotes a so-called substantially cylindrical housing (
Alternatively, the housing 51 may be, for example, a heat conductive material (also referred to as a “frame”).
It is formed by extruding a material such as aluminum having excellent thermal conductivity. Also,
As shown in the figure, the housing 51 is formed with a large number of cooling fins 52L and 52S extending in parallel along a cylindrical rotation axis on the entire outer peripheral surface thereof. In addition, a plane 53 having a relatively large area for mounting the above-described power conversion device (that is, the case for the power conversion device) 30 is formed on a part (the upper portion in the drawing) of the outer peripheral surface of the housing 51. And
Around the periphery, cooling fins 52L that are relatively large (longer) are formed in the horizontal direction.

Note that an armature constituting the stator (stator) 54 of the permanent magnet type rotating electric machine is inserted and fixed in the cylindrical housing 51, and the cylindrical inner space of the armature 54 is inserted. Inside, a rotor (rotor) 55 configured by arranging a plurality of permanent magnets in a cylindrical shape is inserted, and is attached rotatably through a predetermined gap. Reference numeral 56 in the figure denotes a rotating shaft (shaft) that is formed integrally with the rotor (rotor) 55, and the rotational driving force of the rotating electrical machine is driven through the shaft, for example, by a pump or the like. Communicate to equipment. Reference numeral 57 in the figure denotes a housing 5 on the side opposite to the end bracket 11 described above.
1 is an end bracket attached to one end portion, and reference numeral 58 in the drawing denotes a centrifugal fan attached to the rotary shaft (shaft) 56 outside the end bracket 57.

Further, FIG. 5 is an exploded view showing each part when the rotating electrical machine 50 described above is housed in the cover 10 shown in FIG. That is, the rotating electrical machine 50 has a housing 51.
A case for a control & I / F board in which the outer cross section is formed in a substantially arc shape in a part of the outer peripheral surface of the substrate, for example, in the example shown in the drawing, a portion where the relatively short cooling fins 52 around the lower part are formed. 60 and the smoothing capacitor case 70 are attached (or fixed), and then inserted into the cover 10 (see arrows in the figure). Further, the electric power provided in part on the flat surface 53 of the housing 51 is partly provided with a power switching element (for example, IGBT) which is a heating element constituting the inverter through an opening 511 provided in a part of the cover 10. The conversion device 31 is attached to a flat surface 53 formed on a part of the housing 51 of the rotating electrical machine 50, and then a cover (cover for power conversion device) 30 for protection is attached from the outside (see the arrow in the figure). reference). Further, the above-described terminal box (noise filter built-in terminal box) 40 is attached to a part of the outer peripheral surface of the housing 51 (see the arrow in the figure). And the cooling cover 20 mentioned above is attached to the other edge part (left end of a figure) of the housing 51. FIG. Further, reference numeral 21 in the figure indicates a small hole for taking in external air, which is formed in a large number of mesh shapes in the substantially central portion of the wall surface of the cooling cover 20.

That is, according to the rotating electrical machine assembly including the rotating electrical machine main body and the peripheral devices described above, the centrifugal fan 58 attached to the tip of the rotating shaft (shaft) 56 that rotates with the operation of the rotating electrical machine is provided. The air from the outside is guided to the inside of the cover 10, and the housing 51
Heat exchange is performed by flowing between the cooling fins 52 formed on the outer peripheral surface of the outer periphery (see the white arrow in FIG. 4 above), and then through the gap with the end bracket 11 at the other end. To leak. That is, the air flow generated by the rotation of the centrifugal fan 58 cools the housing 51 in which many cooling fins 52 are formed on the outer peripheral surface thereof.

In addition, since the power converter device 31 comprises an inverter as mentioned above, since the power switching element which is a heat generating element is provided in the inside, the emitted-heat amount is large. However, according to the present invention, as described above, the power converter 31 is a part of the housing 51 provided integrally on the outer periphery of the stator (stator) 54 in order to discharge the heat generated by the rotating electrical machine to the outside, that is, , And directly attached to the mounting plane portion 53. According to this,
The heat generated in the power conversion device 31 is transmitted to the housing 51 together with the heat generated by the rotating electrical machine (particularly, the heat generated by the armature), and a large number of the outer peripheral surfaces are arranged in parallel by a material having excellent heat conductivity. By the cooling fins 52 formed in this way, it is efficiently transmitted to the outside air. That is, together with the heat generated by the rotating electrical machine, the heat generated by the power conversion device 31 can be efficiently discharged to the outside, thereby achieving a good cooling effect of the power conversion device.

In particular, in the above-described embodiment, the periphery of the mounting plane 53 formed on the upper portion of the cylindrical housing 51 on which the power converter 31 is disposed is relatively large (extends long) in the horizontal direction.
Since the cooling fins 52 are formed, it is possible to efficiently cool both the heat generated by the rotating electrical machine and the heat generated by the power conversion device 31.

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

  The control & I / F board case 60 includes a control controller (for example, a control microcomputer) and a communication I / F board inside, and a resin material or the like is injected into the case. It has excellent environmental resistance and impact resistance. Then, by attaching the control & I / F board case 60 to a part of the rotating electrical machine, it is possible to perform a wireless / wired communication function with the outside as well as drive control of the outdoor installation pump. In addition, according to this, for example, by mounting a pressure sensor, a flow rate sensor, etc. on the control & I / F board, it is possible to automatically control these amounts as feedback signals, and further to support sensors. By transmitting (communication), centralized management, an integrated energy saving monitor system, and the like can be realized. In other words, this enables operation management and energy-saving operation of an outdoor installation pump, as well as remote monitoring control and centralized management, as well as systemization with multiple pumps, as will be described later. Become.

Further, the capacitor case 70 contains therein a smoothing capacitor that constitutes a part (component) of the inverter circuit of the power converter 31. Similarly to the above, a resin material or the like is contained therein. By injecting, environmental resistance and impact resistance are achieved. Moreover, although the DC reactor which comprises a part of inverter was demonstrated as what was integrated in a part of the said power converter device 31 in this example, this DC reactor is similarly incorporated in an exclusive case. Then, it may be attached to a part of the outer peripheral surface of the housing 51.

In addition, in the present invention, instead of the above-described embodiment, for example, as shown in FIG. 6, the heat generating portion (mesh portion in the figure) H in the power converter 31 is a flat portion of the cylindrical housing 51. 53, a stator (armature) which is a heat generating part on the rotating electric machine side on the rotation center axis.
For example, it is arranged so as to be located closer to the centrifugal fan 21 built in the cooling cover 20 than the position of the central portion 54 (indicated by a broken line B in the figure). According to this, efficient cooling can be achieved by dispersing the heat generating parts without concentrating.

Furthermore, as shown in FIG. 7, the stator (armature) 54 is cut out at a part of the outer periphery thereof, in particular, a portion close to the flat portion of the housing 51 to which the power conversion device 30 described above is attached ( A cut portion 541), a so-called cut core, can also be employed. According to this, the power converter 30 and the stator (armature) 54, which are heat generating parts, are thermally separated at the cut portions, whereby the absorption of heat by the housing 51 is separated and cooled efficiently. It becomes possible.

As described above, according to the pump device of the present invention, as is clear from the above description, the housing in which the cooling fins are formed on the outer periphery is directly used as a cooling unit for heat-generating parts such as an inverter. , A power converter including an inverter, various circuit boards, and a noise filter and a capacitor. That is, in the present invention, by adopting a permanent magnet motor, the size of the motor can be made smaller than the size of the induction motor. Then, by arranging parts such as the power conversion measure and control board around the housing as described above, the outer shape of the pump device equipped with the induction motor having the same output performance as the outer dimensions and having the control panel separately. It becomes possible to provide a pump device having a size equal to or smaller than the size. In other words, it can be replaced with a pump device equipped with an existing induction motor,
A control panel is not required, and a significant space saving can be realized.

In addition to external dimensions, a heat pump that can be driven practically can be obtained by adopting the heat dissipation structure as described above for heat dissipation, which has been a conventional problem. Can do.

In the present invention, since it is a drive unit control device integrated pump device that sells hot water vinegar with the above-described features, there is no need to separately install a control panel, and a portable terminal or pump for a plurality of pump devices Control can be easily performed from a monitoring station or a master machine of the same type of pump device.

Control of the drive unit control device integrated pump device taking advantage of the above features will be described with reference to FIGS.

FIG. 8 is a flowchart of a control method when a plurality of pumps of the same type are used. While the pump is stopped (101), it is determined that the pump needs to be started when the amount of water increases from the predetermined reference or the pressure falls below the predetermined reference (102), and one pump starts up. (103). On the other hand, when the amount of water decreases (104), it is not necessary to start the pump, so the pump stop state is continued (101).

Even when one pump is in operation (201), it is determined that further pump activation is required when the water volume increases above a predetermined standard or the pressure falls below a predetermined standard (202), and One pump is started (203). On the other hand, when the amount of water is reduced (204), it is not necessary to start the pump, so that one pump is stopped (2).
05).

Further, even when two pumps are in operation (301), it is determined that further pump activation is required when the water volume increases from a predetermined reference or the pressure falls below a predetermined reference (302). One pump is started (303). On the other hand, when the amount of water decreases (304), the stoppage of one pump is stopped (305). For three or more units, control is performed according to the same flow as described above.

Control of the pump as described above is performed from a pump monitoring station or a master device of the same type of pump device for a plurality of drive unit control device-integrated pump devices as shown in FIG.

A confirmation of the current state, an operation start instruction, an operation stop instruction, etc. are sent to each pump apparatus from a pump monitoring station or a master machine of the same type of pump apparatus. Such an instruction is performed by wireless communication such as a wireless LAN or Bluetooth (registered trademark) built in the control & I / F board of the pump device or a control signal line (wired).

In communication, an identification number is assigned to each pump device. The control board of the pump device includes a storage unit and has an area for storing an identification number unique to the pump device. Data is transmitted according to a communication format determined in advance using a randomly generated number other than a predetermined number (for example, 0000 to 0099) as an identification number. If data is transmitted from the pump monitoring station or the master device of the same type of pump device to the pump device but there is no reply, the communication is retransmitted after a randomly determined time. When there is a reply, the identification number (for example, 0000 to 0099) designated by the reply data is used as the identification number of the pump device. In order to prevent communication from colliding, the pump devices to which 0000 to 0099 are assigned are set to refrain from communication for a certain period of time so that communication other than 0000 to 0099 can be performed after each communication.

When the pump device fails, the fact that the pump device has failed is communicated via communication. Pump monitoring station,
If there is a faulty pump device, the pump device master machine that manages the number of operating units stops the pump device and starts the alternative pump device.

In addition, the monitoring device or pump device that monitors the pump device is the operation status of other pumps (the content of the failure if it is in failure), the history of the failure, the number of pump devices of the same type installed, the same type of pumps It has an area for storing the number of devices that can be connected in parallel, the number of pump devices that are currently operating, and the number of pump devices that are malfunctioning. By outputting these information to the portable terminal, the status of all pump devices by communicating with one monitoring device or pump device (overall status)
Can be grasped.

  Furthermore, when the control board of the pump device has a position information detection device (for example, a GPS device), the installation position of the pump device can be grasped, and a plurality of pump devices are provided for each position of the pump device. Can be grouped and controlled.

In this case, the identification number of the pump is sent together with the data in order to clarify the object to which the data is transmitted. The wireless interface and the storage unit are incorporated in the control & I / F board (1-8, 2-8, 3-8) of the pump device.

The mobile terminal preferably includes a display device, and the display on the mobile terminal displays not the data content itself but a converted version (for example, 0 → pump stop, 1 → pump operation, etc.). . In the mobile terminal, even when the driving status and the history of failure are acquired, for example, if the error code represents the failure content, the content indicated by the error code is displayed (for example, if the error code “E1” is “overcurrent”, The display is as shown in “Overcurrent”).

Next, when the operation status acquisition command is given from the portable terminal, the operation status is stored in the storage unit that stores the pump operation data through the wireless interface (1-8, 2-8, 3-8) of the pump device. Data is read, and the read data is sent to the mobile terminal through the wireless interface.

Further, when the pump is operated from the portable terminal, it is possible to give an operation / stop command and to set the operating frequency (motor rotation speed) in the same manner as data setting.
