A control panel 30 (corresponding to a control device) for controlling the operation of the water supply pump 11 is attached to the inside of the case body 18 immediately above the water supply pump 11 arranged at the uppermost stage. It is.

An accumulator 31 for maintaining the water supply pressure at a predetermined level is provided in the case inside immediately above the suction header 20 and the discharge header 21 adjacent thereto. Specifically, the accumulator 31 is fixed to the discharge header 21 by a bracket 31a as shown in FIG. 3, and is installed above the suction / discharge headers 20, 21. In addition,
The accumulator 31 communicates with the discharge header 21 via a communication pipe 31b.

Due to the structure of supporting the upper and lower two-stage water supply pump 11 on the gantry side, the structure of supporting the suction side device on the gantry side, the structure of supporting the discharge pipe 23a on the gantry side, and the structure of supporting the accumulator 31 on the discharge header 21, Equipment around the pump including the water supply pump 11 that causes generation of water (water supply pump 11, piping, accumulator 31a)
Is housed in the case 17 without touching the case 17.

The side of each water supply pump 11, the suction header 20, the discharge header 21, the front of the control panel 30, and the accumulator 31 face from the opening 18a of the case body 18. Each part of the device can be seen, and a work space necessary for taking in and out each device can be obtained. Note that a window 19 a is formed in the door 19 so that the meters of the control panel 30 can be visually recognized.

The place where the control panel 30 is located is shown in FIGS.
As shown in FIG. 5, the partition is formed by an L-shaped partition wall 32 extending continuously from the back surface in the case body 18 to the opening 18a. Specifically, the vertical portion of the partition wall 32 is continuous with the ceiling surface of the case body 18, and the horizontal portion of the partition wall 32 is continuous with the left side surface of the case body 18, forming a partition space 33 in the same portion. ing. The control panel 30 is accommodated in the partition space 33.

On the inner surface of the door 19a facing the end of the partition wall 32, a heat insulating member, for example, a urethane foam member 33a is attached in an inverted L-shape according to the shape of the partition wall 32. When the 19a is closed, the urethane foam member 33a comes into close contact with the end of the partition wall 32 to seal between them.

External pipes (not shown) are connected to the suction port 28 and the discharge port 29 through the soil (ground). Of course, holes are formed in the cover 34 so that the suction port 28 and the discharge port 29
May be connected to a pipe from outside.

In such a water supply apparatus, the water supply pump 11 is installed on the plurality of pump installation sections 6 and 10 formed on the upper part of the gantry, and the case 17 is installed on the upper part of the gantry so as to surround the periphery of the water supply pump 11. , Water supply pump 1
Since the water supply pump 11 is housed in the case 17 without touching the inner surface of the case 1 with the water supply pump 11, the water supply pump 11 can be stored in a multi-story structure which reduces the floor space occupied by the water supply pump. In addition, vibration from the water supply pump 11 is not transmitted to the case 17.

As a result, noise caused by the vibration of the case 17 can be reduced, and the noise reduction can be achieved while reducing the occupied floor area. Moreover, since the suction header 20 and the discharge header 21 extending in the vertical direction are supported by the connection with the suction part 11b / discharge part 11c of the water supply pump 11, the vertical piping structure which is excellent in space saving is kept as it is. Vibrations transmitted from the header 20 and the discharge header 21 (suction / discharge piping) to the case 17 can be eliminated.

In addition, since the control panel 30 is incorporated above the uppermost feed pump 11 and the accumulator 31 fixed to the discharge header 21 is incorporated above the suction header 20 / discharge header 21, the exclusive floor space is reduced. In addition, vibration transmitted from the accumulator 31 to the case 17 can be eliminated.

By the synergistic effect of these effects, the noise caused by the vibration of the case 17 is greatly reduced, and a water supply device excellent in installation and quietness can be provided. In addition, since all the openings on the four sides of the gantry 1 are covered with the cover 34, the noise of the water supply pump 11 radiated to the outside from between the legs 3 and 3 of the gantry 1 can be reduced, and the noise can be further reduced. A water supply device with excellent performance can be provided. In addition, since the urethane foam member 35, which is a heat insulating member, is attached to the inner surface of the cover 34, the suction side device installed in the gantry 1 is kept warm, and a water supply device excellent in freezing prevention is provided. it can.

In addition, the case 17 for accommodating such a pump device does not need to have much mechanical strength because the heavy device is not fixed.
, And thus the water supply device.

Also, since the main body case 18 through which the internal equipment faces the opening 18a and the doors 19a and 19b for opening and closing the opening 18a of the main body case 18 are employed, maintenance of the equipment in the case can be easily performed. it can.

Further, a partition wall 32 is provided in the main body case 18.
The control panel 30 is accommodated in the partition space 33, and the urethane foam member 3 which is a heat insulating member is formed.
At 3a, the space between the door body 19a and the closed door body 19a is sealed to seal the partition space 33, so that the control panel 30 is isolated from the water supply pump 11, the piping, and the accumulator 31. As a result, the water supply pump 11 Of the motor 11b can be prevented from entering the control panel 30, and water leakage from the piping can be prevented from entering the control panel 30 and flooding. In addition, the partition wall 32 also improves the mechanical strength of the case body 18.

The bottom surface of the case 17 and the upper surface of the gantry 1 are both frame-structured and open, so that even if water leakage occurs during the test operation of the pump, or even if condensation water is generated, Since it flows out without staying at the bottom of the case 17, an increase in the humidity inside the case 17 is suppressed, and there is no danger that various electric components and mechanical components are corroded by the humidity.

In the embodiment, a water supply device in which water supply pumps are accommodated in two upper and lower stages is taken as an example. However, the present invention is not limited to this, and it is also applicable to a water supply device in which water supply pumps are accommodated in more stages. Not even.
