Description

[0001] Duplicated watering system for booster pump [0002]

The present invention relates to a water supply system, and more particularly, to a booster pump system for supplying water to a building or a housing complex, a water supply system of a double booster pump capable of using the water source on the inflow side of the water supply facility in parallel with a water storage tank .

Generally, a booster pump for supplying water required for a building such as a building or a housing complex generally supplies water from a water source for the above-mentioned function and supplies the water to a necessary place. In the conventional water source-booster pump inter- Is shown in Fig.

As shown in FIG. 1, a plurality of booster pumps P are supplied with water in an arrow direction from a water supply pipe 10 connected from a water supply source (not shown). In the general water supply system, The booster pump 10 is provided with a water storage tank 20 capable of storing a predetermined amount of water without passing water directly to the booster pump P and a connection pipe 30 is provided between the water storage tank 20 and the booster pump P, Respectively. The water provided by the water supply pipe 10 is stored once in the water storage tank 20 and the water stored in the water storage tank 20 is pressurized through the connection pipe 30 via the booster pump P Through the water supply pipe (40).

The reason for configuring the water supply system as described above is that since the distance between the booster pump P and the water source (not shown) is long, it is difficult to draw water from the water source (not shown) The booster pump P is installed in the water storage tank 20 so that the booster pump P is installed in the water storage tank 20 when necessary. It is to supply water.

However, the conventional water supply system has the following disadvantages. First, the water supply system constructed as above includes a water supply pipe 10, a water storage tank 20, a connection pipe 30, and a booster pump P, In the event that an abnormality occurs on either side, for example, when leakage of water or foreign matter into the pipes (10, 30) or the water storage tank (20) occurs, the entire water supply is stopped, There arises a problem that the suspended state continues.

Also, in the same context as the above-mentioned problem, since the water in the water tank 20 may stay in the water for a long time, problems such as hygiene may occur. Therefore, the water needs to be periodically cleaned.

In the water supply system constructed as described above, when the booster pump P uses water in the water storage tank 20, since the pressure on the suction side is low, the booster pump P pumps water through the water supply pipe 40 at a high pressure For example, when the water needs to be supplied to a high-rise building or a remote area of a building, the amount of operation of the booster pump P must be increased, which inevitably causes power consumption and is uneconomical.

In addition, since the water supply system is provided with water only through the water tank 20, a sufficient water storage amount in the water tank 20 must be provided. Therefore, the water tank used for the water tank 20 must be designed to have a large volume. Occurs. Such a large water tank not only generates an economical additional cost but also causes a waste of unnecessary space. However, in the conventional water supply system, when water stored in the water storage tank 20 is used up, it is impossible to supply water. Therefore, it is inevitable that the volume of the water storage tank 20 is designed to be large. There is no.

As a prior art related to the water supply system, a pressurized water supply system includes a water supply line instead of the water tank of the pressure field, as well as a water supply line through which water is supplied from a water source to a plurality of pressure chambers, A pressurized water supply and reception system in which a water supply line is directly connected to pressurized water supply and reception is disclosed in Patent Document 10-2007-0104322 (hereinafter referred to as Prior Art 1).

However, the above-described prior art 1 is a technology for directly feeding raw water lines and water supply lines, and is a completely different technology from the present invention in which water supply systems are duplicated using existing waterworks.

In addition, Patent Document 10-0454677 (hereinafter referred to as "Prior Art 2") discloses a water-based air-boosting type air-conditioning system capable of supplying water and fire for 20 minutes or more at a high- As the water supply device, the above-mentioned prior art 2 relates to a hydraulic ground-operated air supply water supply device which is regulated by a transverse type pressure-regulated water supply tank portion, a hydraulic ground-operated valve portion, a gas bottle collecting device portion, a small-

However, the prior art 2 described above is different from the present invention in that the present invention, which is an invention related to a general water supply facility, is related to a fire water supply system, and as a water supply system using a public water supply pressure, The present invention aims to provide a technology that is different from the present invention in both its configuration, orientation and method.

In the prior art 3, the water of a water source such as ground water or a reservoir is pumped and stored in a remote water reservoir This is a technology that controls the water level in the water tank to be in an appropriate range in a simple watering facility that supplies water to the user.

However, as described above, the prior art 3 is completely different from the present invention by the technique related to the water tank as described above.
