Abstract
The utility model discloses a chemical process pump. The chemical process pump comprises a pump body (1), an impeller (2), a mechanical seal (3), a pump shaft (4) and a bearing (5), wherein a flow stabilizing plate (6) is axially arranged below an inlet of the pump body (1). The chemical process pump has the advantages of simple structure, reasonable design, convenience in use, long maintenance cycle, low maintenance cost, long service life and the like.
Description
Technical field
The utility model relates to pump, and a kind of chemical flow-process pump is provided especially.
Background technique
Chemical flow-process pump is one of visual plant in Chemical Manufacture, but, through being everlasting, prewhirling appears existing chemical flow-process pump in impeller eye place, net positive suction head does not reach requirement, wherein, net positive suction head causes the mechanical seal of pump housing choma and bearing damage, the cost of use that has strengthened user, causes damage, and causes the service cycle of chemical flow-process pump to shorten.
Therefore, how chemical flow-process pump is carried out to architecture advances, become people's problem demanding prompt solution.
Model utility content
The problems such as Given this, the purpose of this utility model is to provide a kind of chemical flow-process pump, and prewhirling appears in the impeller eye place that chemical flow-process pump existed in the past at least to solve, net positive suction head does not reach requirement, and user loses greatly, and process pump service cycle is short, expense height.
The technological scheme that the utility model provides is: a kind of chemical flow-process pump, comprise the pump housing 1, impeller 2, mechanical seal 3, pump shaft 4 and bearing 5, and it is characterized in that: below the ingress of the pump housing 1, be axially provided with stabilier 6 along it.
Preferably, described stabilier 6 is up-narrow and down-wide trapezium structure.
Further preferably, described stabilier 6 is integral type structure with the pump housing 1.
The chemical flow-process pump that the utility model provides; by set up stabilier below the ingress of the pump housing; improve inlet area; avoid impeller to occur prewhirling in ingress and cause cavitation erosion, improve the cavitation performance of pump, protection pump exempts from the damage that backflow, the separation of flow and cavitation cause; reduce user's maintenance cost; increase the repair cycle, made process pump can carry out long time running, enhanced productivity.
The chemical flow-process pump that the utility model provides, have simple in structure, reasonable in design, easy to use, the advantage such as service cycle is long, and maintenance cost is low, long service life.
Brief description of the drawings
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of chemical flow-process pump.
Embodiment
Be illustrated in figure 1 a kind of chemical flow-process pump, comprise the pump housing 1, impeller 2, mechanical seal 3, pump shaft 4 and bearing 5, below the ingress of the pump housing 1, be axially provided with stabilier 6 along it.
The chemical flow-process pump that the utility model provides; set up stabilier by the ingress at the pump housing; can prevent that prewhirling from appearring in impeller eye place; improve the cavitation performance of pump; protection pump exempts from the damage that backflow, the separation of flow and cavitation cause, has reduced user's maintenance cost, has increased the repair cycle; make process pump can carry out long time running, enhance productivity.
In order to improve the effect of stabilier, as the improvement of technological scheme, as shown in Figure 1, stabilier 6 is designed to up-narrow and down-wide trapezium structure, compare foursquare stabilier, the stabilier of this trapezium structure is not easy to produce and departs from, and the size of stabilier can be carried out free design along with the size of pump.
In order to prevent stabilier accidental from the pump housing, as the improvement of technological scheme, stabilier 6 and the pump housing 1 are adopted to the integral structure of casting, improve the fastness being connected between stabilier and the pump housing.
Embodiment in the utility model is to write according to the mode of going forward one by one, and highlights the difference of each embodiment, and its similar part can cross-references.
By reference to the accompanying drawings mode of execution of the present utility model is described in detail above, but the utility model is not limited to above-mentioned mode of execution, in the ken possessing those of ordinary skill in the art, can also under the prerequisite that does not depart from the utility model aim, make various variations.
Claims (3)
1. a chemical flow-process pump, comprises the pump housing (1), impeller (2), mechanical seal (3), pump shaft (4) and bearing (5), it is characterized in that: the below, ingress at the pump housing (1) is axially provided with stabilier (6) along it.
2. according to chemical flow-process pump described in claim 1, it is characterized in that: described stabilier (6) is up-narrow and down-wide trapezium structure.
3. according to chemical flow-process pump described in claim 1, it is characterized in that: described stabilier (6) is integral type structure with the pump housing (1).
