For example, as shown in FIG. 8, the fire pump includes a pump 101, a drive motor 102, a control panel 103, a suction pipe port 104, a discharge pipe port 105, a valve 106, a flexible pipe 107, a test device (test pipe) 108, In many cases, the devices constituting the fire pump 100 such as the expiratory water tank 109 and the pressure tank 110 are set as one unit according to the specifications, and these devices are integrally installed on a common base 111 (for example, Patent Document 1).

JP 2000-93543 A

  In the unitized fire-extinguishing pump 100, a large-sized pump 101 and a drive motor 102 are used if the discharge capacity is large, and the amount of electric power required to operate the pump 101 having a large flow rate increases. The control panel 103 accommodates electrical devices such as large transformers, inverters, and breakers having a large output, and the volume of the control panel 103 increases and becomes heavy.

  In this case, as shown in FIG. 9, together with the components of the large pump 101, the drive motor 102, and the fire pump 100, a large control panel 103 is installed on a common base 111 through a frame 112. When the fire pump 100 is unitized, the control panel 103 protrudes from the base 111 to the side. Therefore, it is necessary to take measures to prevent the unit from falling over before it is installed at the installation site or during loading and installation work. If the control panel 103 is installed on the frame 112, there is a problem that the operation position of the control panel 103 is increased and the operability is lowered.

Of course, if the vertical and horizontal widths of the base 111 are widened to increase the installation area of the equipment, the large control panel 103 can be stably installed at a position that does not protrude from the base 111. The increase in the production cost such as the cost of the steel materials and welding that are the constituent materials, and the weight of the base 111 increases and the unitized fire pump 100 as a whole becomes heavy in weight. There is a problem that it is difficult to carry in and install the installation site using a large transport equipment.
The fire-extinguishing pump 100 is often installed in a narrow space with a limited installation area such as a basement of a building. When the base 111 is enlarged to increase the installation area of the fire-extinguishing pump 100 and the overall weight is increased, the installation is performed. A lot of labor is required for carrying in to the place and installation work, and the installation construction cost is inevitably high.

  In view of such problems of the prior art, the present invention aims at a large-sized pump or drive motor without increasing the size of the base, even in a pressurized water supply unit having a large discharge capacity. The control panel can be stably installed and supported on the base, and can be installed in a narrow installation space by a simple operation.

In order to solve the above-mentioned problem, the pressurized water supply unit of the present invention is a pressurized water supply unit in which a pressurized water supply apparatus component device including a pump, a drive motor and a control panel is installed on a base.

The control panel is installed on each equipment component other than the control panel and the auxiliary base, and the control panel is installed separately, and then transported to the installation site. Both bases are connected together at the loading location to form a pressurized water supply unit. Can be installed.
By making the auxiliary base on which the control panel is installed separate from the main base, a large pump or drive motor can be installed on the base of an existing size without making the base large, and unitized. There is no cost for producing a large base, and a pressurized water supply unit with a large discharge capacity can be constructed and installed at a low cost.
In addition, since the main base and auxiliary base can be transported in a separated state, it takes less time to carry in the installation site, and even when the installation space is small, each separated base can be carried in. The installation of the place can be done easily. In addition, the auxiliary base where the control panel is installed is connected to the main base in parallel, and before the equipment is brought into the installation site, the mounting position of the electrical equipment such as pumps and drive motors and the control panel must be specified. As a result, electrical wiring at the installation site can be performed with simple work.
