Description

[Detailed Description of the Invention] The present invention relates to a pump device that can be installed even in narrow spaces.

A pressure tank is also usually used in pump equipment, but when this pressure tank is installed above the pump body,
There are various cases, such as when it is installed on the bottom or on the side.

However, in pump devices that use a so-called preload pressure tank whose interior is partitioned into a pressure chamber and an ice chamber by a flexible membrane, the pressure tank is often installed next to the pump body to simplify assembly.

FIG. 1 shows a conventional example, in which a pump main body 2 is installed on a base 1, a self-priming tank 3 is connected to the discharge side of the main body, and a pipe 4 is drawn out from the self-priming tank.
In many cases, a pre-pressure type pressure tank 5 is connected in the middle.

Although this makes it easy to connect the pressure tank 5, it has the disadvantage of requiring a large installation area.

The present invention reduces the installation area by projecting a pressure tank upward from the discharge side of the pump via a pull-out pipe, and also covers the pump with a cover having an opening larger than the pressure tank, and provides service to the opening. The service batch is designed to keep the pump warm by blocking it with a batch.The service batch is provided with a notch through which the extraction pipe passes, so that the service batch can be removed when priming water, and rainwater and dust are removed from this notch. It is covered with a waterproof cap to prevent foreign substances from entering.

The present invention will be explained below based on FIG.
A pressure tank 11 is provided protruding from a self-priming tank 9 connected to the discharge side of the pump body via a pull-out pipe 10.

Reference numeral 12 denotes a suction pipe connected to the suction side of the pump 8 via a check valve 13, and has a piping connection portion 14 protruding from its lower end.

Further, 15 is a discharge pipe, the upper end of which is connected to the self-priming tank 9, and a piping connection portion 16 similarly protruding from the lower end.

Furthermore, 17 is a cover, which covers the pump 8 and the self-priming tank 9 and fits into the base 7, and the cover 17 fits into the base 7.
A notch 18° 18 is provided at a position facing 4.16, and an opening 19 larger than the diameter of the pressure tank 11 is provided in the ceiling surface.

Reference numeral 20 denotes a service batch that closes this opening, and a part of the service batch is provided with a notch 21 through which the extraction pipe 10 passes, so that the service batch can be attached without passing through the pressure tank 11.

If this notch exists, there is a risk that rainwater may enter the cover 17 from here, so in order to avoid this, a waterproof cap 22 is loosely fitted to the extraction pipe 10, and the notch 21 is covered with the cap. covered.

Reference numeral 23 denotes a plug for a self-priming water inlet drilled in the self-priming tank 9. When filling self-priming water into the self-priming tank 9, the service hatch 20 and this plug 23 are removed.

Further, 24 is a pressure switch connected to the side of the self-priming tank.

Furthermore, the pressure tank 11 is a so-called pre-pressure type pressure tank whose interior is partitioned into an air chamber and an ice chamber via a partition membrane (not shown), and is screwed to the upper end of the extraction pipe 10.

As described above, the present invention has a pressure tank 1 on the upper side of the pump body 8.
1, the installation area is small, and an opening 19 is provided on the upper surface of the cover 17 that covers the pump body 8, and a service hatch 20 that closes the opening is provided with a pressure tank 11.
Since a cutout 21 is provided for passing the extraction pipe 10,
This service hatch 20 can be easily removed, making it easy to inject priming water and inspect the inside.

Furthermore, since a waterproof cap 22 is attached to the extraction pipe 10 to cover the notch 21, rainwater will not enter the cover 17 from the notch 21, and the opening 19 bored in the cover will not leak into the pressure tank 11. Since the diameter of the cover 17 is larger than that of the cover 17, there is no problem in attaching and detaching the cover 17 during assembly or repair, and this has a great practical effect.
