Description

Stamping sewage pump

Technical Field

The utility model relates to the field of sewage pumps, in particular to a stamping sewage pump.

Background

The sewage pump is a sewage conveying device, is usually latent underwater, and is used by combining a submersible motor, while the traditional sewage pump generally comprises an upper end cover, a motor shell, an oil chamber, a pump body, a base and the like, and the parts are mostly cast parts, wherein the motor shell is arranged below the upper end cover, and the two parts are independent parts and are connected by bolts; the motor casing then bearing is in the grease chamber top, and the grease chamber lower extreme is connected with the pump body, and pump body below is connected with the base, and grease chamber, the pump body, base adopt the components of a whole that can function independently structure, and three adopts bolted connection respectively for independent part, and consequently such structure leads to the spare part of dredge pump more, and the processing degree of difficulty increase moreover, the unable effectual assurance of concentricity, manufacturing cost is high moreover, adopts the foundry goods to be unfavorable for the environmental protection mostly simultaneously.

Disclosure of Invention

The utility model aims to provide a stamping sewage pump with a new structure, few components, simple structure and more reasonable structure, wherein an upper end cover and a motor shell in the stamping sewage pump adopt an integrated structure, and the material of a casting is changed into the material of stamping stainless steel; the oil chamber, the pump body and the base also adopt an integrated structure, so that the processing steps can be simplified, the processing precision is improved, the number of parts is greatly reduced, and the manufacturing cost is reduced, and the utility model provides the following technical scheme for realizing: the utility model provides a punching press dredge pump, includes upper end cover, motor casing, grease chamber, the pump body, base, pump mouth ring, the motor casing is located the upper end cover below, with pump body connection, the pump body bearing is in grease chamber below, the base supports in pump body below, its characterized in that: compared with the prior art, the utility model has the following beneficial effects that the upper end cover and the motor shell are of an integrally formed integral structure, and the oil chamber, the pump body and the base are of an integrally formed integral structure: preferably, upper end cover and the integrative stretch forming of motor casing adopt the tensile casting of replacing of panel, reduce environmental pollution, utilize the environmental protection, and can reduce manufacturing cost, preferably, grease chamber, the pump body, base casting are integrative, and casting integrated into one piece can be better for the assurance that is divided into the structure concentricity of three part, and the assembly is simpler, can also guarantee the reliability of dredge pump simultaneously, preferably, grease chamber, the pump body, base casting are integrative, and the grease chamber design is conical, and the external diameter is less than the pump body, guarantees the stability of dredge pump when effectively reducing casting cost.

Drawings

The utility model will be further described in detail with reference to the accompanying drawings and specific embodiments, wherein fig. 1 is a schematic structural diagram of the utility model; FIG. 2 is a schematic view of a motor housing portion of the present invention; FIG. 3 is a schematic view of a pump body portion of the present invention; in the figure: 1-motor shell, 11-upper end cover, 2-pump body, 21-oil chamber, 22-base and 3-pump mouth ring.

Detailed Description

In order to make the technical means, the original characteristics, the objectives and the functions of the present invention easy to understand, the present invention will be further explained with reference to the specific drawings, and in the description of the present invention, unless otherwise specified and limited, the terms "mounted", "connected" and "connected" should be understood broadly, for example, they may be fixedly connected, detachably connected, integrally connected or mechanically connected, or electrically connected, or directly connected with each other or indirectly connected through an intermediate medium, and can be connected inside two elements, such as a stamping sewage pump shown in fig. 1, 2 and 3, which includes a motor housing 1, an upper end cover 11, a pump body 2, an oil chamber 21, a base 22, and a pump mouth ring 3, wherein the upper end cover 11 is located above the motor housing 1 and is integrally formed by stretching a plate material, the pump body 2, the oil chamber 21 and the base 22 are integrally formed by casting, the pump ring 3 is connected below the pump body 2 by bolts, the upper end cover 11 and the motor casing 1 are preferably integrally formed by stretching, the pump body 2, the oil chamber 21 and the base 22 are preferably integrally formed by casting, and what should be finally explained is that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the utility model.
