Abstract

PURPOSE:To reduce the number of parts and to make the partition at the strainer section movable by providing an integrated strainer and pump fixing foot at the suction port of pump. CONSTITUTION:Fixing feet 11 are provided at the suction port of pump impeller 2 to be driven through a motor 1, while partition boards 15 are provided in grid together with the fixing holes 12 to constitute a strainer section 14. The pump is secured to said feet 11 to filter the water through the strainer section 14 and to suck through the suction port 8. Consequently, conventional strainer is not required resulting in reduction of the number of parts.

Description

[Detailed description of the invention] [Technical field of invention] This invention relates to a water pump.

[Prior art]

FIGS. 1 and 2 are a plan view and a sectional view of a conventional water pump. (1) is a motor and is fixed to the uke (4) with a motor fixing screw (6). The motor shaft (5) is
4) is passed through the air hole Ql, and the blade (2) is attached to the penetrated part. The casing (3) is attached to the housing (4) by casing attachment screws (7). The pump is fixed by inserting the suction port (8) of the casing (3) into the fixing hole 0 of the fixing leg αυ. A strainer is installed around the fixed foot αυ to prevent foreign matter from getting stuck in the pump.

A conventional pump is configured as described above, with a motor (1)
When starts rotating, the blade (2) directly connected to the motor @ (5) starts rotating, which applies centrifugal force to the water. As a result, water flows through the inlet of the casing (3) (
8) It is sucked in and discharged from the discharge port (9). As shown in Figure 1, the center of gravity is high.

In addition, since the casing (3) has an inverted conical shape, the pump itself is unstable, and the pump always requires a fixed foot αυ, and a strainer Q to prevent pump jamming.
3 was also needed. For this reason, there were drawbacks such as a large number of parts to be attached to the bomb and high cost.

It was also necessary to change the type of mesh on the strainer side depending on the type of water being sucked up.

[Summary of the invention]

This invention was made with the aim of improving such drawbacks, and it also integrates the strainer and fixed foot, which were conventionally attached as separate parts. By integrating the strainer and fixed foot with the casing, the number of parts can be reduced, and
To provide a pump in which the size of the mesh can be varied by making a part of the strainer movable.

[Embodiments of the invention]

FIGS. 3 and 4 are a plan view and a sectional view showing an embodiment of the present invention. fil~α1 is the same as the conventional pump. The α force is a fixed leg, with fixing holes and a partition plate α9 arranged in a lattice pattern to form a part of the strainer.

The pump configured as described above is fixed to the fixed foot I, and the water is filtered through a portion of the strainer (+4+) provided with the fixed foot I, and is sucked through the suction port (8) and then sucked into the discharge port (8). 9) Strainer (0 stage), which was required in the past, is no longer required, reducing the number of parts.In addition, the time required to install the strainer (8) is also eliminated, making it easier to assemble the pump. Time has decreased.

It has become possible to reduce costs by reducing the number of pump parts and assembly time.

FIGS. 5 and 6 are a plan view and a sectional view showing another first embodiment of the present invention. (1) to (21) and (41 to 41) are the same as those of the conventional pump. (3) is a casing with a fixed foot part (Le) and a part of the strainer (+7).

In the embodiment shown in FIG. 2, the strainer and the fixed leg are integrated, but in this embodiment, the casing of the pump and the fixed leg of the strainer 1 are also integrated.

The pump configured as described above is fixed at the fixed foot part αQ of the casing, and the water is passed through the strainer part a of the casing.
D is filtered, sucked in through the suction port (8), and discharged through the discharge port (9). Conventional for this reason.

The fixed foot aυ and strainer 031 that were required are no longer necessary, and the number of two parts has been greatly reduced. Also, the fixed foot aυ
and strainer - αQ) Since no installation time is required, the pump assembly time has been greatly reduced. By significantly reducing the number of pump parts and the assembly time, it has become possible to significantly reduce costs.

FIG. 14 is a plan view, a sectional view, and a detailed view showing another second embodiment of the present invention. (11~f2+, f41~0
Q is the same as the conventional pump. (3) is the casing, with a fixed leg (IQ) and a part of the strainer provided with α force.A hole (L) in the center of the temporary partition.

The core frame (11 is a through hole. Therefore, the partition plate α9
can freely rotate around the core frame αl. This reduces the roughness of the mesh of the strainer part αη.
It is now possible to change to T.

The pump configured as described above is fixed at the fixed foot part (If9) of the casing, and water is passed through the strainer part aη of the casing, sucked in through the suction port (8), and discharged from the discharge port (9). Since the partition plate (2) of the casing strainer is movable, the roughness of the mesh can be changed by moving the partition plate a according to the type of water to be sucked up.

This reduces costs and eliminates the need to change the strainer depending on the type of water pumped, as was the case in the past.

〔Effect of the invention〕

As explained above, the effect of this invention is that it requires fewer parts to be installed compared to conventional products.

Costs can be significantly reduced. ′=1:ta. By making part of the strainer as shown in Figures 1 to 9, you can change the roughness of the mesh depending on the type of water being sucked up.

Depending on the type of water to be sucked up, there are great effects such as no need to prepare a strainer.
