Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pump device in which a booster that has a rod shape and circulates a liquid to be treated around a motor part of a land pump and cools the motor part is housed in a booster housing case.
[0002]
[Prior art]
A conventional booster, for example, a land pump used on land, is installed with the motor part and the pump part exposed to the air.
When electric power is supplied to the motor unit of such a land pump and the pump is operated, the rotating blades of the pump unit rotate, so that the pump unit pumps the liquid flowing into the inflow port with the rotating blades and sends it out from the outflow port.
The heat generated by the operation of the motor unit is radiated to the atmosphere around the motor unit.
[0003]
[Problems to be solved by the invention]
Since the conventional land pump is air-cooled as described above, in order to efficiently dissipate the heat generated by the operation of the motor unit, the motor casing is made of a good thermal conductor and the motor casing has cooling fins. A large number of ventilation holes for heat dissipation are provided in the motor casing.
Therefore, since it is necessary to secure a heat radiation space for circulating the air around the land pump to dissipate the heat of the motor unit, the installation space becomes wide and the space cannot be used effectively.
[0004]
Also, in order to prevent the operating noise of the motor part from leaking to the outside, for example, even if the land pump is covered with a soundproof box, heat is accumulated in the soundproof box, and the above-mentioned heat radiation space is secured. In view of what must be done, it is difficult to provide compact and effective sound insulation measures.
Furthermore, even if it is compact, there is a disadvantage that noise is leaked because a ventilation hole such as a gallery for heat dissipation and a sufficient space are required.
[0005]
Therefore, the present applicant has proposed a booster that cools the motor part by circulating a liquid to be handled around the motor part in a bar shape, according to Japanese Patent Application No. 5-47104 and Japanese Patent Application No. 5-47105.
However, the booster previously proposed by the applicant also has points to be improved in terms of soundproofing and coldproofing.
[0006]
The present invention has been made to solve the above-described disadvantages, and can be used effectively with a small installation space. Effective soundproofing, coldproofing and dustproofing can be performed with a small volume. Provided is a pump device that can handle the above.
[0007]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view in which a booster storage case of a pump device according to an embodiment of the present invention is broken, and FIG. 2 is a front view of a state in which a door of the pump device according to an embodiment of the present invention is closed.
In these figures, 1 is a water inlet pipe, 2A, 2B are valves connected to the water inlet pipe 1, 3A is a booster connected to the valve 2A, 3B is a booster connected to the valve 2B, and each booster 3A, 3B Is a water-cooled type in which a liquid to be handled, for example, water is circulated around the motor unit to cool the motor unit.
[0009]
And each booster 3A, 3B is made into the rod shape where each shaft of a motor part and a pump part was comprised by one shape, and an inflow port and an outflow port are formed concentrically with a shaft at the both ends, for example. ing.
Reference numeral 4 denotes a water discharge pipe connected to the boosters 3A and 3B.
[0010]
Reference numeral 11 denotes a booster storage case, which is a rectangle that is substantially sealed, and is formed in a flat box shape.
The front surface is covered with a door 11d whose center is the right side, the water inlet pipe 1 passes through the lower side of the left side surface 11sl, and the water outlet pipe 4 passes through the upper side of the right side surface 11sr.
Reference numeral 12 denotes a soundproofing material, which is disposed on the entire inner surface of the booster storage case 11.
Reference numeral 13 denotes a water draining mechanism, which is provided on the bottom surface 11 f of the booster storage case 11.
[0011]
The plane connecting the centers of the boosters 3A and 3B and the back surface 11r and the door 11d of the booster storage case 11 are substantially parallel.
Further, legs 11b for floating the drainage mechanism 13 are provided at the four corners of the bottom surface 11f.
Further, as a matter of course, the soundproof material 12 is also disposed on the inner surface of the door 11d.
[0012]
Next, the operation and action will be described.
First, when the water usage point is in a water usage state, for example, the booster 3A is driven and controlled by a control unit (not shown).
When the booster 3A is activated, the water flowing into the booster 3A from the water inlet pipe 1 through the valve 2A is pumped by the booster 3A and sent out to the water use location through the water outlet pipe 4.
Therefore, water is fed by the booster 3 </ b> A until the water use place is in a water non-use state.
[0013]
When water is supplied to the water use site in this way, an operating noise is generated by operating the booster 3A. This operating noise is generated when the booster storage case 11 is in a substantially sealed state and the soundproofing material 12 acts on the booster. No leakage to the outside of the storage case 11.
And the heat which generate | occur | produces when the motor part of booster 3A or booster 3B act | operates is conveyed with the water which flows around a motor part, and is thermally radiated.
Further, the water leaked from the boosters 3A and 3B during the repair and inspection of the boosters 3A and 3B is discharged to the outside of the booster storage case 11 by the drainage mechanism 13.
[0014]
As described above, according to the embodiment of the present invention, since the boosters 3A and 3B are water-cooled, it is not necessary to provide a space for heat dissipation around the boosters 3A and 3B. Therefore, the installation space can be reduced, the space can be used effectively, and maintenance and inspection can be facilitated.
[0015]
Since the boosters 3A and 3B are arranged on the same plane and accommodated in the booster storage case 11, the door 11d and the back surface 11r of the booster storage case 11 are made substantially parallel to the plane on which the boosters 3A and 3B are arranged. , also the water inlet pipe 1 and the water outlet tube 4, booster 3A, since disposed on a plane by arranging 3B, compact, blanking Suta 3A, the booster housing case 11 substantially as flattened consisting of an outer diameter thickness 3B is Since it can be formed, compact soundproofing measures, cold protection measures and dustproof measures can be taken.
[0016]
Therefore, since the boosters 3A and 3B are rod-shaped, they can be accommodated or embedded in the wall, hung on the wall, the boosters 3A and 3B can be placed vertically, and the boosters 3A and 3B can be placed horizontally. To increase.
Moreover, the booster housing case 11 to the booster 3A of substantially sealed state acoustic insulation 12 is disposed on the entire inner surface, since the housing a 3B, booster 3A, even operation sound is generated by the 3B is actuated, operating sound Will not leak to the outside, and will exhibit further soundproofing and dustproofing effects.
[0017]
Further, since the surroundings of the boosters 3A and 3B are covered with the soundproofing material 12 and the booster storage case 11, the boosters 3A and 3B are not directly exposed to the outside air, thereby exhibiting a cold protection effect.
And since the drainage mechanism 13 was provided in the bottom face 11f of the booster storage case 11, the water which leaked from the boosters 3A and 3B at the time of repair inspection can be discharged | emitted to the exterior of the booster storage case 11.
[0018]
In the above-described embodiment, an example in which only the boosters 3A and 3B are accommodated in the booster storage case 11 has been described. However, in addition to the boosters 3A and 3B, a control device that drives and controls the boosters 3A and 3B is accommodated. also not good.
[0019]
The detailed description of the water draining mechanism 13 as a liquid draining mechanism is omitted, but it may be a discharge cylinder or a discharge cylinder with a cock.
[0020]
【The invention's effect】
As described above, according to the present invention, since the booster is water-cooled, there is no need to provide a space for heat dissipation around the booster. Less space can be used effectively, and maintenance and inspection can be facilitated.
And since the plurality of boosters were arranged on the same plane and accommodated in the booster storage case, the front and back of the booster storage case were made substantially parallel to the plane on which the plurality of boosters were arranged. the water outlet pipe, since disposed on a plane by arranging a plurality of booster, a compact, substantially because the flattened booster housing case which is the thickness of the outer diameter can be formed, compact soundproofing measures blanking Suta, warm measures and dustproof Measures can be taken.
[0021]
Therefore, because the booster has a rod shape, the degree of freedom to accommodate or embed in the wall, hang it on the wall, place the booster vertically, or place the booster horizontally increases. Impossible breakthrough installation forms can be provided.
Further, since the housing a plurality of booster booster storage case substantially sealed state, further, since the provided acoustic insulation in all the inner surface of the booster housing case, even if the operation sound is generated by the booster is actuated, actuation Sound is prevented from leaking to the outside, and a further soundproofing effect and dustproofing effect can be obtained.
[0022]
Furthermore, since the periphery of the booster is covered with the soundproofing material and the booster storage case, the booster is not directly exposed to the outside air, so that a further soundproofing effect and a coldproofing effect can be obtained.
And since the liquid draining mechanism was provided in the bottom face of the booster storage case, the liquid which leaked from the booster at the time of repair inspection can be discharged | emitted outside by a liquid draining mechanism.
