Abstract
The utility model relates to a pump, in particular to a centrifugal pump with high lift and high pressure, comprising a spiral case, a vane wheel, a pump shaft and a sealing member. The tangency position of the parallel line of the central shaft of the fluid issuing and the diameter of the vane wheel is the cutting isolation point of the fluid. Because the fluid is drained in a linear mode at the outlet, and the fluid power is not wasted, the centrifugal pump has the advantage of high lift and large pressure. Simultaneously, because the distance of the cutting isolation point and the low pressure area is increased, the short-circuit phenomenon of the fluid is reduced.
Description
Technical field
The utility model relates to a kind of pump, particularly a kind of centrifugal pump with high-lift high pressure.
Background technique
Existing centrifugal pump, fluid cut out isolating points above the water outlet of spiral case, this design that cuts out isolating points can cause the power of fluid to decompose and the short circuit phenomenon of fluid, thereby makes lift of pump, pressure reduction.
Technology contents
The purpose of this utility model provide a kind of have pressure, lift high from anti-pump, to overcome the deficiencies in the prior art.The utility model is to improve to realize that be made up of spiral case, impeller, pump shaft and Sealing, main points of the present utility model are that the parallel lines and the tangent place of impeller diameter of fluid output central shaft is that fluid cuts out isolating points on the basis of existing centrifugal pump.The utility model is because fluid is that straight line is discharged in outlet, and do not have the fluid dynamic loss, thereby has lift height, advantage that pressure is big, owing to cut out isolating points and low pressure area apart from increase, reduced the short circuit phenomenon of fluid simultaneously.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
Specific embodiment
1 is spiral case of the present utility model among the figure, and impeller, pump shaft and Sealing are installed in the spiral case 1, and spiral case has fluid output 2, and its technological points is: the tangent place of the parallel lines of the central shaft of fluid output and impeller diameter is that fluid cuts out isolating points.
Claims (1)
1, a kind of centrifugal pump is made up of spiral case (1), and spiral case is equipped with impeller, pump shaft and Sealing in (1), and spiral case has fluid output (2), it is characterized in that: the tangent place of the parallel lines of the central shaft of fluid output and impeller diameter is that fluid cuts out isolating points.
