Abstract
The utility model relates to a kind of water pump vane, specially a kind of tight-holding type impeller hub, including the axis connection portion being connected as one and blade mounting portion, the end in the axis connection portion is provided inwardly with skirt, and the width of the skirt is the 1/3-1/2 of axis connection portion radius；Angle between the axis connection portion and blade mounting portion is obtuse angle.The upper end of the wheel hub of the utility model is provided inwardly with skirt, and impeller press-assembling rear package power on axis is big, and transmitting torque is big, and up to 45N.m or more, impeller is not easily to fall off, more safe and reliable than traditional impeller hub open type.
Description
Technical field
The utility model relates to a kind of water pump vane, specially a kind of tight-holding type impeller hub.
Background technique
Water pump vane is driven by motor to be rotated, and makes medium by centrifugal force or lifting force, medium is made to have machinery
Energy.Its core component as water pump, shape and size and pump performance have substantial connection, are the main influences of working efficiency
Element.Water pump vane generally can be divided into single-suction and two kinds of double-suction type, and single-suction impeller is unilateral water suction, and small flow water pump impeller is more
For such pattern.Double-sided impeller is both sides water suction, and big flow water pump vane is all made of double-sided impeller.Under specific operation,
If Impeller Design is bad will to generate hydraulic loss and gap loss at pump intake and blade.
As shown in Figure 1, for impeller hub frequently with open type, transmitting torque is only 30N.m or so, impeller in the prior art
It is easy to fall off, safety is low.
Summary of the invention
The utility model aims to solve the problem that the above problem, provides a kind of tight-holding type impeller hub, impeller press-assembling is on axis
Package power is big afterwards, and transmitting torque is big, and impeller is not easily to fall off.
According to the technical solution of the utility model, shown tight-holding type impeller hub, wheel hub includes that the axis being connected as one connects
Socket part and blade mounting portion, the end in the axis connection portion are provided inwardly with skirt, and the width of the skirt is axis connection portion radius
1/3-1/2；Angle between the axis connection portion and blade mounting portion is obtuse angle.
Further, the impeller hub is using stamping.
Further, the angle between the axis connection portion and blade mounting portion is 93-98 °.
Further, the angle between the axis connection portion and blade mounting portion is 95 °.
The utility model has the beneficial effects that: the upper end of wheel hub is provided inwardly with skirt, impeller press-assembling on axis after pack tightly
Power is big, and transmitting torque is big, and up to 45N.m or more, impeller is not easily to fall off, more safe and reliable than traditional impeller hub open type.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the prior art.
Fig. 2 is the structural schematic diagram of the utility model.
Description of symbols: 1- axis connection portion, 2- blade mounting portion, the skirt 3-, 4- blade.
Specific embodiment
The utility model is described in further detail with attached drawing combined with specific embodiments below.
As shown in Figure 2: the utility model tight-holding type impeller hub is pacified including the axis connection portion 1 being connected as one and blade
Dress portion 2.The end in axis connection portion 1 is provided inwardly with skirt 3, and the width of skirt 3 is the 1/3-1/2 of 1 radius of axis connection portion, specific
Radius size appropriate adjustment of the ratio according to axis connection portion 1, the package power being subject to after guaranteeing impeller press-assembling on axis.Axis connection
Angle between portion 1 and blade mounting portion 2 is obtuse angle.
Specifically, impeller hub, using stamping, processing quality is stable, consistency is good, high in machining efficiency, operation side
Just, it is desirable that worker's industrial grade it is not high, die life is long, and production cost is low.Axis connection portion 1 and blade mounting portion 2 it
Between angle be 93-98 °, blade 4 is mounted on the end of blade mounting portion 2.Axis connection portion 1 and blade peace in one embodiment
Angle between dress portion 2 is 95 °.
The utility model impeller hub upper end is tight-holding type, i.e., is provided inwardly with skirt 3, impeller in the end in axis connection portion 1
Package power is big after being fitted on axis, and transmitting torque is big, and up to 45N.m or more, impeller is not easily to fall off, securely and reliably.
