Abstract
The utility model discloses a stainless steel multiple-stage centrifugal pump. The stainless steel multiple-stage centrifugal pump comprises a base, a motor installed on the base, and a pump body installed on the base, wherein the pump body is provided with a shell body, a shaft installed in an inner cavity of the shell body and an impeller installed on the shaft, the shaft is connected with a power output end of the motor, and the shell body is provided with a water inlet end and a water outlet end. The stainless steel multiple-stage centrifugal pump is characterized in that the water inlet end and/or the water outlet end are/is provided with an inner thread structure, the inner thread structure is provided with an installation head with a flange disc in a matched mode, and the installation head is provided with an outer thread sleeve matched with the inner thread structure. The stainless steel multiple-stage centrifugal pump has the advantages that the whole stainless steel multiple-stage centrifugal pump not only can be installed through a flange disc structure and external equipment, but also can achieve threaded connection with the external equipment under the condition that the installation head is detached, the whole stainless steel multiple-stage centrifugal pump is provided with a TiAlN composite ceramic coating and a TiCN coating, and corrosion resistance is largely improved.
Description
Technical field
The utility model relates to a kind of stainless steel multistage centrifugal pump.
Background technique
For applicable to carrying for the stainless steel multistage centrifugal pump of slight Korrosionsmedium, the Placement of itself and external equipment is comparatively single, and its structure adopts stainless steel to make conventionally, although have certain anti-corrosion capability, whole structure is not satisfactory.
Model utility content
The purpose of this utility model is exactly in order to address the above problem, and a kind of stainless steel multistage centrifugal pump is provided.
To achieve these goals, the utility model adopts following technological scheme:

Accompanying drawing explanation
Fig. 1 is stainless steel multistage centrifugal pump structural representation.
Description of reference numerals:
1. pedestal; 2. motor; 3. the pump housing; 4. housing; 5. axle; 6. impeller; 7. mounting head.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
In literary composition, "/" represents the implication of "or".
As shown in Figure 1, stainless steel multistage centrifugal pump, it comprises: the pedestal 1 of its carrying effect; Power be provided to stainless steel multistage centrifugal pump and be installed on the motor 2 of pedestal, it adopts the mode that level installs and makes pto＝power take-off in level; Be installed on the pump housing 3 of pedestal, the impeller 6 that it has a housing 4, is installed on the axle 5 of housing inner chamber and is installed on axle, described axle is connected in motor power output terminal, the left end of described housing has a feed-water end and a waterexit end of being located at housing top, and feed-water end and waterexit end are positioned in two orthogonal directions substantially; The inwall of described feed-water end is provided with female thread structure, this female thread structure coordinates the mounting head 7 that a flanged dish is installed, this mounting head has an external thread sleeve coordinating with female thread structure, the medium transport channel part that extends to feed-water end at external thread sleeve is provided with external thread structure, and this external thread sleeve extended distance should not be too large.
For guaranteeing the airtight performance of whole mounting head, the surface of contact of described mounting head and feed-water end is provided with flexible seal ring/sealing gasket, such as rubber seal or rubber gasket.
Consider the particularity of fed sheet of a media, such as with mild corrosion medium, described housing, axle, impeller are provided with TiA1N composite ceramic coat and TiCN coating, the two be used in conjunction with adhesion and the antiseptic effect that contributes to strengthen corrosion-inhibiting coating.
When needs are used connection structure of ring flange, mounting head installation in position, coordinate the flange plate of mounting head to be connected with external equipment, if to using worm structure to connect, remove mounting head and can use threaded connection, brought great convenience and versatility to the installation of external equipment.
The foregoing is only preferred implementation of the present utility model, protection domain of the present utility model is not limited in above-mentioned mode of execution, and every technological scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvement of carrying out under the prerequisite that does not depart from principle of the present utility model, these improvement also should be considered as protection domain of the present utility model.
