Description

  The present invention relates to a packaged water supply pump device that houses a pump and a control unit in a housing.

  In the pump device, a package type water supply pump device that does not require a pump room and can be installed outdoors, for example, in a space next to a building or under a stair landing is proposed.

  This type of packaged water pump apparatus employs a structure in which a pump and a control unit that controls the pump are housed in a single housing.

  On the other hand, a pump usually includes a motor as a drive source. This motor generates heat when driven. In addition, the controller that controls the driving of the motor also generates heat during driving. These motors and control units generate a relatively large amount of heat as compared to other components constituting the pump device.

Therefore, a cooling structure is provided in the packaged water supply pump apparatus having the above-described casing. As an example of the cooling structure, for example, there is a water cooling type (for example, refer to Patent Document 1).
Japanese Patent Laid-Open No. 8-319997

  In the packaged water supply pump device disclosed in Patent Document 1, the motor and the control unit are accommodated in the same casing. By housing the motor and the control unit that generate a large amount of heat in the same casing, the temperature rise in the casing increases.

  Therefore, the cooling structure provided in the housing is required to have a performance that suppresses the temperature rise caused by the two heating elements described above. However, an increase in the amount of heat generated in the housing is not preferable because the cost can be increased by improving the performance of the cooling structure.

  Accordingly, the present invention has been made based on such circumstances, and it is an object of the present invention to obtain a packaged water pump device that can effectively suppress the temperature rise in the housing.

  In order to achieve the above object, a packaged water pump apparatus according to one embodiment of the present invention includes a pump unit and a control unit. The pump unit includes a first housing and a pump accommodated in the first housing. The control unit includes a second housing and a control unit accommodated in the second housing. The first casing and the second casing are connected to each other.

  According to this configuration, the pump and the control unit that generate a large amount of heat are housed in separate housings, so the amount of heat generated in each housing is small. That is, the temperature rise in each housing is suppressed.

  In a preferred embodiment of the present invention, the pump unit includes a first door member that closes a first carry-in port for carrying the water supply pump into the first housing. The control unit includes a second door member that closes a second carry-in port for carrying the control unit into the second casing.

  In a preferred embodiment of the present invention, the packaged water pump device has a first carry-in port for carrying the water feed pump into the first housing and a second carry-in device for carrying the control unit into the second housing. A door member that closes the carry-in entrance is provided.

  In a preferred embodiment of the present invention, the first housing has an opening. When the pump unit and the control unit are connected to each other, the opening is sealed by the peripheral edge of the opening coming into contact with the second housing.

  The first casing 21 and the second casing 31 are fixed by a fixing structure 50. The fixing structure 50 includes a first through hole 51, a second through hole 52, a bolt 53, and a nut 54.

  The first through hole 51 is formed in the first upper wall 21 a of the first housing 21. In the present embodiment, the first through holes 51 are formed, for example, on both sides of the front edge of the first upper wall 21a, that is, on the first left and right walls 21c and 21d side. The first through hole 51 penetrates the first upper wall 21a in the vertical direction. The upper surface of the first upper wall 21a is a plane.

  The second through hole 52 is formed in the second lower wall 31 b of the second housing 31. The second through hole 52 is arranged at a position facing the first through hole 51 when the second casing 31 is arranged on the upper surface of the first upper wall 21a. The lower surface of the second lower wall 31b is a flat surface, for example.

  Therefore, the upper surface of the first upper wall 21a and the lower surface of the second lower wall 31b are in surface contact. In this way, the second casing 31 is stably fixed to the first casing 21 by surface contact.

  FIG. 4 is a front view of the packaged water pump device 10 with the first and second door members 23 and 32 removed.

  As shown in FIG. 4, a pump unit 22 is accommodated in the first housing 21. The pump unit 22 includes a water supply pump 60, a piping unit 70, a backflow prevention circuit 80, a flow rate sensor 90 (shown in FIG. 5), an accumulator 100, and the like. The configuration of the pump unit 22 described above is an example.

  The feed water pump 60 is a pump referred to in the present invention. The water supply pump 60 is, for example, a vertical pump. For example, three water supply pumps 60 are arranged on the upper portion of the first housing 21 along the left-right width direction, for example. The feed water pump 60 includes, for example, an electric motor 61 and a multistage turbine-type pump main body 62. The electric motor 61 is an example of a drive source. The feed water pump 60 includes the electric motor 61 as a drive source, so that the amount of heat generated during driving increases. The pump body 62 is connected to the output shaft of the electric motor 61. The feed water pump 60 having the above configuration is arranged such that the electric motor 61 is on the top and the pump body 62 is on the bottom.

  The piping unit 70 includes a suction header pipe 71, a discharge header pipe 72, and the like. FIG. 5 is a partial cross-sectional view of the packaged water supply pump apparatus 10 from which the first left wall 21c is omitted as viewed from the left side. In FIG. 5, the accumulator 100 is omitted.

  As shown by a dotted line in FIG. 5, the suction header pipe 71 is disposed immediately below each pump body 62. The suction header pipe 71 extends along the width direction of the first housing 21. The width direction of the first casing 21 is a direction from the first left wall 21c toward the first right wall 21d, and a direction from the first right wall 21d toward the first left wall 21c.

  A maintenance on-off valve 63 is attached to the suction port 62 a of each pump body 62. The maintenance on-off valve 63 is connected to the suction header pipe 71.

  The discharge header pipe 72 is disposed directly under the pump main body 62. The discharge header pipe 72 extends in the width direction of the first housing 21. In FIG. 5, the discharge header pipe 72 is partially cut.

  As shown in FIG. 4, the suction header pipe 71 and the discharge header pipe 72 are connected to each other via a bypass check valve 66. At the time of high pushing-in of the water guided to the water supply pump 60, the water is discharged from the suction header pipe 71 without passing through the water supply pump 60 and is sent to the header pipe 72.

  As shown in FIG. 5, the discharge port 62 b of each pump main body 62 opens toward the front. Therefore, the discharge port 62 b of each pump body 62 is connected to the discharge header pipe 72 using the discharge pipe 64. The discharge pipe 64 incorporates a check valve (not shown). A flow rate sensor 90 is attached to the discharge pipe 64.

  As described above, the discharge header pipe 72 is disposed immediately under the pump main body 62. Therefore, as shown in the drawing, the discharge pipe 64 is bent downward and has, for example, a substantially L shape. One end of the discharge pipe 64 is connected to the discharge port 62 b of the pump body 62. The other end of the discharge pipe 64 is connected to a discharge header pipe 72.

  As shown in FIG. 4, the discharge header pipe 72 is connected to the first connecting pipe 73. The first connecting pipe 73 is provided on the first right wall 21 d of the first housing 21. The first connecting pipe 73 passes through the first left wall 21 c and protrudes into the first housing 21. Therefore, one end of the first connecting pipe 73 is opened in the first housing 21.

  One end 72 a of the discharge header pipe 72 is connected to one end 73 a of the first connecting pipe 73 (one end opened in the first housing 21).

  The other end 73b of the first connecting pipe 73 (the end protruding outside the first housing 21) is connected to a water supply pipe (not shown). The water pipe goes to each household.

  The accumulator 100 is connected to the discharge header pipe 72.

  The second connecting pipe 75 passes through the first right wall 21 d of the first housing 21. The second connecting pipe 75 passes through the first right wall 21d. Therefore, one end 75 a of the second connection pipe 75 is open in the first housing 21.

  The other end 75 b of the second connection pipe 75 protrudes outside the first housing 21. The other end 75b of the second connecting pipe 75 forms a suction port connected to a water main pipe (not shown). The second connecting pipe 75 is disposed below the first connecting pipe 73, for example.

  As shown in FIGS. 4 and 5, the backflow prevention circuit 80 is disposed between the suction header pipe 71 and the second connection pipe 75.

  Due to the relative positional relationship between the suction header pipe 71 and the second connecting pipe 75, the backflow prevention circuit 80 is disposed below and forward of the water supply pump 60 and the pipe portion 70. Therefore, the suction header pipe 71 and the backflow prevention circuit 80 are connected to each other via the relay pipe 76. In view of the above arrangement, the relay pipe 76 is formed in a substantially U shape obliquely downward and forward.

  The backflow prevention circuit 80 includes a first ball valve 81, a backflow prevention device 82, and a second ball valve 83. The backflow prevention circuit 80 is connected to each other in the order of the first ball valve 81, the backflow prevention device 82, and the second ball valve 83.

  The first ball valve 81 is connected to the second connecting pipe 75. The second ball valve 83 is connected to the relay pipe 76. A drain pipe 84 is connected to the backflow prevention device 82.

  An electrical component 33 is accommodated in the second casing 31. As an example, the electrical component unit 33 includes an inverter 101, a DC reactor 103, a control panel 104, and the like. The control panel 104 is a control unit referred to in the present invention. An inverter 101 and a DC reactor 103 are prepared for each water supply pump 60. The configuration of the electrical unit 33 is not limited to the above.

  The control panel 104 is connected to each water supply pump 60 by a communication cable 105. FIG. 6 shows an enlarged view of F6 surrounded by a two-dot chain line in FIG. For this reason, as shown in FIGS. 2, 4, and 6, a through hole 106 is formed in the first upper wall 21 a of the first housing 21. A through hole 107 is formed in the second lower wall 31 b of the second housing 31 corresponding to the through hole 106. The communication cable 105 passes through the through holes 106 and 107. Seal members are interposed in the through holes 106 and 107 so that heat does not move between the first and second casings 21 and 31 through the through holes 106 and 107. In the present embodiment, for example, a rubber bush 108 is provided as a seal member, for example.

  As shown in FIGS. 1 and 2, the second door member 32 is formed with a window 130 through which the control panel 104 can be confirmed from the outside.

  In the packaged water supply pump device 10 configured as described above, the water supply pump 60 is accommodated in the first housing 21. The control panel 104 is accommodated in the second casing 31. The electric motor 61 of the feed water pump 60 and the control panel 104 generate a large amount of heat.

  Thus, by accommodating the feed water pump 60 and the control panel 104 that generate a large amount of heat among the components that constitute the pump device in separate housings, the temperature rise in the housings 21 and 31 is suppressed. The

  More specifically, when the water supply pump 60 and the control panel 104 are housed together in one casing, the temperature in the casing rises due to the heat generation of the water supply pump 60 and the heat generation of the control panel 104. To do.

  However, as described above, the water supply pump 60 is accommodated in the first casing 21 and the control panel 104 is accommodated in the second casing 31, whereby the temperature in the first casing 21 is increased. The temperature inside the second casing 31 rises due to the heat generated by the control panel 104.

  That is, the temperature in the first casing 21 is not affected by the control panel 104, and the temperature in the second casing 31 is not affected by the water supply pump 60. The temperature rise in 21 and 31 is suppressed. Therefore, the temperature increased by the feed water pump 60 and the temperature increased by the control panel 104 do not affect each other.

  In particular, it is conceivable that the control panel 104 loses its efficient operation due to a rise in temperature. Therefore, it is not preferable that the temperature rises. The temperature of the control panel 104 is affected by the temperature around the control panel 104, that is, the temperature inside the second casing 31.

  Therefore, as described above, since the ambient temperature of the control panel 104 is not affected by the heat generation of the feed water pump 60, the efficient operation of the control panel 104 is not lost.

  Further, the communication cable 105 that electrically connects the water supply pump 60 and the control panel 104 is passed through the through holes 106 and 107 by passing through the through holes 106 and 107 with a sealing member such as the rubber bush 108. The movement of air between the casings 21 and 31 is suppressed.

  Therefore, the movement of temperature between the first and second casings 21 and 31 through the through holes 106 and 107 is prevented.

  In the present embodiment, the rubber bush 108 is interposed in the through holes 106 and 107 through which the communication cable 105 passes. However, the present invention is not limited to this. For example, when a cable such as the communication cable 105 passes through the walls of the first and second casings 21 and 31, a seal member such as a rubber bush 108 may be interposed in the through hole.

  In addition, since the pump unit 22 including the water supply pump 60 is accommodated in the first casing 21, the sound absorber 26 that absorbs these noises is concentrated on the first casing 21. become.

  Therefore, noise can be effectively suppressed while suppressing the range in which the sound absorber 26 is provided.

  In addition, since the electrical unit 33 and the pump unit 22 are housed in separate housings, even if water leakage occurs in the first housing 21, water may be applied to the electrical unit 33. Is prevented.

  Further, it is conceivable that there is a difference between the temperature of water in the piping unit 70 and the backflow prevention circuit 80 and the temperature in the housing. For this reason, when the said temperature difference becomes large, such as summer and winter, dew condensation tends to occur in the housing.

  However, since the pump unit 22 and the electrical component unit 33 are housed in separate housings, the electrical component unit 33 is not affected by condensation.

  The first and second door members 23 and 32 are used to block the first and second carry-in ports 24 and 34. Therefore, since the first and second door members 23 and 33 only need to have a size that covers only the corresponding first and second carry-in ports 24 and 34, an increase in weight is suppressed.

  Furthermore, when the 1st and 2nd door members 23 and 32 are used, when maintaining the pump part 22 and the electrical equipment part 33, only a required one can be opened.

  More specifically, for example, when the pump unit 22 is maintained, only the first door member 23 needs to be opened. Similarly, when the electrical component part 33 is maintained, only the second door member 32 needs to be opened. Thus, maintainability improves by opening only a required door member.

  Moreover, since the pump part 22 is provided with the water supply pump 60 and the piping part 70, it becomes larger than the electrical equipment part 33. Therefore, the first housing 21 is larger than the second housing 31.

  Therefore, even if no air inlet / outlet is formed in the first housing 21 in particular, the space in the first housing 21 is increased, so that the temperature in the first housing 21 is less likely to rise. .

  Moreover, the package-type water supply pump apparatus 10 is divided into two parts, that is, the pump unit 20 and the control unit 30, so that the first casing 21 has a size that accommodates the pump unit 22. . The second housing 31 only needs to have a size for housing the electrical component 33.

  Therefore, the height of the first housing 21 can be made lower than the height of the housing used when the pump unit 22 and the electrical component unit 33 are accommodated in one housing. Similarly, the height of the second casing 31 can be made smaller than the height of the casing used when the pump unit 22 and the electrical component unit 33 are accommodated in one casing.

  Therefore, the rigidity required for the first casing 21 of the pump unit 20 is smaller than the rigidity of the casing when the packaged water supply pump device 10 is configured by one casing.

  Therefore, the first upper wall 21a, the first lower wall 21b, the first left wall 21c, the first right wall 21d, the first front wall 21e, and the first rear wall 21f are combined into a package type water supply pump device. 10 can be made thinner than the wall portion of the housing in the case of a single housing.

  The same applies to the second casing 31 of the control unit 30.

  As described above, when the packaged water supply pump device 10 includes the pump unit 20 and the control unit 30, it is possible to thin the wall portion constituting the first housing 21 and the second housing 31. As a result, the cost of the packaged water pump device 10 can be reduced.

  Next, a packaged water pump device 10 according to a second aspect of the present invention will be described with reference to FIGS. In addition, the structure which has a function similar to 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits description.

  In the present embodiment, the first carry-in port 24 and the second carry-in port 34 are closed by one door member 110. Other structures may be the same as those in the first embodiment.

  This point will be specifically described.

  FIG. 7 is a front view of the packaged water supply pump apparatus 10 of the present embodiment. FIG. 8 is a side view of the state in which the door member 110 is removed as viewed from the side.

  As shown in FIGS. 7 and 8, the door member 110 is large enough to block the first and second carry-in ports 24 and 34 in a state where the second housing 31 is fixed to the first housing 21. have.

  Further, the packings 25 and 35 are connected to the first and second casings through the first and second carry-in ports 24 and 34 when the door member 110 is blocking the first and second carry-in ports 24 and 34. Measures are taken to prevent the temperature in 21 and 31 from moving.

  In the present embodiment, in addition to the effects of the first embodiment, the use of the door member 110 instead of the first and second door members 23 and 32 reduces the number of parts, thereby reducing the cost.

  Next, a packaged water pump device 10 according to a third embodiment of the present invention will be described with reference to FIG. In addition, the structure which has a function similar to 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits description.

  In the present embodiment, the first casing 21 and the fixing structure 50 between the first casing 21 and the second casing 31 are different from those in the first embodiment. Other structures may be the same as those in the first embodiment.

  This point will be specifically described.

  FIG. 9 shows a state in which the first and second casings 21 and 31 of the present embodiment are disassembled. In FIG. 8, the first and second door members 23 and 32 are omitted. The pump unit 22 and the electrical unit 33 are schematically shown by a two-dot chain line.

  As shown in FIG. 9, in the first casing 21 of the present embodiment, an opening 120 is formed in the first upper wall 21a. The opening 120 is formed over substantially the entire region, for example, leaving the peripheral edge 121 of the first upper wall 21a. The opening 120 passes through the first upper wall 21a.

  For example, a dust-proof rubber 122 is provided as a seal member over the entire area of the peripheral edge 121 of the opening 120. As shown in the first embodiment, the first upper wall 21a of the first casing 21 and the second lower wall 31b of the second casing 31 have substantially the same shape. Therefore, when the second casing 31 is fixed to the first casing 21, the opening 120 of the first upper wall 21a is closed by the second lower wall 31b. The opening 120 is sealed with a dustproof rubber 122.

  The fixing structure 50 includes an L-shaped member 123, a bolt 53, and a nut 54. A through hole 123 b through which the bolt 53 passes is formed in one wall portion 123 a of the L-shaped member 123. The L-shaped member 123 is provided on the first left and right walls 21c and 21d. The L-shaped members 123 provided on the first left and right walls 21c and 21d are arranged on the upper portions of the outer surfaces of the first left and right walls 21c and 21d with the wall portion 123a in which the through hole 123b is formed facing upward.

  In addition, two L-shaped members 123 are provided at the bottom of the outer surfaces of the second left and right walls 31c and 31d. The L-shaped member 123 provided in the second left and right walls 31c and 31d has a wall portion 123a such that the through hole 123b faces the through hole 123b of the L-shaped member 123 provided in the first left and right walls 21c and 21d. Is arranged in a posture positioned below.

  Therefore, after the control unit 30 is placed on the pump unit 20, the L-shaped member 123 provided on the second left and right walls 31c and 31d and the L-shaped member 123 provided on the first left and right walls 21c and 21d. The pump unit 20 and the control unit 30 are fixed to each other by tightening with a nut 54 through a bolt 53.

  In the present embodiment, the opening 120 is formed in the first upper wall 21a of the first casing 21, so that the efficiency of the work of arranging the pump unit 22 in the first casing 21 is improved, and the work The degree of freedom increases.

  Further, by providing the dust-proof rubber 122 at the peripheral edge 121 of the opening 120, the opening 120 is sealed, so that rain or the like can be prevented from entering the first housing 21.

  In addition, in this embodiment, although the opening 120 was formed in the 1st upper wall 21a, it is not limited to this. For example, when the pump unit 20 and the control unit 30 are connected to each other in a state where the first left wall 21c and the second right wall 31d are in close contact with each other, the opening 120 is formed in the first left wall 21c. May be formed.

  In short, the opening 120 may be formed in a contact portion of the first housing 21 that contacts the second housing 31.
