Abstract
The utility model relates to a novel pipeline pump, which comprises a motor, a pipeline pump body, an impeller, an inlet flange and an outlet flange. The utility model is characterized in that the horizontal centerlines of the inlet flange and the outlet flange are positioned on one same horizontal line and are lower than the centerline of the impeller. The utility model has the advantages that the size of the suction section of the pump is reduced under the condition of the satisfaction of the reduction of the hydraulic loss of the pipeline pump and the suction performance of the pipeline pump, and thus, production cost is reduced and the service performance of the pump is increased.
Description
Technical field
The utility model relates to a kind of pump, particularly a kind of late-model inline pump.
Background technique
Traditional pipeline mounted pump enters the impeller of pump relatively smoothly in order to guarantee medium at present, and guarantee the flange bolt connection space of pump inlet and pipeline simultaneously, impeller central lines in the center line of the import and export flange of general pipeline mounted pump and the pump, and impeller center line minimum range of height at the bottom of the pump, therefore existing pipeline mounted pump is in order to satisfy above-mentioned requirement, the length of its suction casing and tortuosity all have a restrictive condition, as the length of wanting to shorten suction casing certainly will to make that then suction casing becomes flat, and in order to guarantee the minimum range of impeller center line at the bottom of the pump, then the length of suction casing will prolong, so for the requirement on the usability that satisfies pipeline mounted pump, corresponding size can only be amplified, the result causes the installation dimension of pump to strengthen, weight improves, and has strengthened cost of production, and pump inlet simultaneously is also longer to the impeller inlet distance, so make that the hydraulic loss of pump is bigger, suction performance reduces.
Summary of the invention
The purpose of this utility model is the installation dimension increasing that solves the center line and the existing pump of impeller central lines in the pump of the import and export of pipeline mounted pump in the prior art, weight improves, pump its hydraulic loss when work is bigger, the problem that suction performance reduces, provide a kind of in light weight, size is little, and hydraulic loss is little, the late-model inline pump that imbedibility is good.The utility model designs a kind of late-model inline pump, comprise motor, the pipeline pump housing, impeller, suction flange, outlet(discharge) flange, it is characterized in that: the horizontal center line of suction flange and outlet(discharge) flange is positioned on the same horizontal line, and the horizontal center line of suction flange and outlet(discharge) flange is lower than the center line of impeller.The utility model has the advantages that under the condition that the imbedibility that satisfies pipeline mounted pump and hydraulic loss reduce, dwindle the suction casing size of pump, thereby reduced cost of production, improved the usability of pump.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
Embodiment
Comprise motor 1, the pipeline pump housing 2, impeller 3, suction flange 4, outlet(discharge) flange 5 among the figure, it is characterized in that: the horizontal center line of suction flange 4 and outlet(discharge) flange 5 is positioned on the same horizontal line, and the center line of suction flange 4 and outlet(discharge) flange 5 is lower than the center line of impeller 3.As shown in drawings, the common center line of suction flange 4 centers of pipeline mounted pump 1 and outlet(discharge) flange 5 is moved down a distance from the center line level of impeller 3, because suction flange 4 centers of pipeline mounted pump 2 and the common center line of outlet(discharge) flange 5 move down a distance from the center line level of impeller 3, therefore have under the minimum value situation that satisfies the waterpower requirement satisfying the distance of impeller 3 center lines to base, the inlet pipeline of pump can have the bigger stretching, extension curved space, satisfying under the water inlet requirement smoothly, make the suction casing of pump 2 fuller, the length of suction casing reduces, in addition, liquid changes less by the direction that pump inlet flow into impeller inlet, be that hydraulic loss reduces, improve the suction performance of pump, and satisfied the installing space of suction flange connecting bolt.
Claims (1)
1, a kind of late-model inline pump, comprise motor, the pipeline pump housing, impeller, suction flange, outlet(discharge) flange, it is characterized in that: the horizontal center line of suction flange and outlet(discharge) flange is positioned on the same horizontal line, and the horizontal center line of suction flange and outlet(discharge) flange is lower than the center line of impeller.
