Abstract
The utility model discloses a kind of vertical pump axle stretch end sealing structure, for preventing gap of the water flow between the gap and fan blade and shaft outside shaft and motor between seat from entering inside motor, is also formed with bearing between the shaft and the outer seat of motor；Wherein, the sealing structure has the fan blade being set in shaft section of stretching out and supports the gasket on shaft end face and fan blade by screw fit sealing, and the fan blade is formed and covered from top to bottom the gap between shaft and the outer seat of motor using totally-enclosed face.Compared with prior art, the utility model is realizing that a bit friction energy loss is completely absent when sealing loses, and due to not any wearing detail, therefore also has the characteristics that long service life.
Description
Technical field
The utility model relates to the field of sealing technology of the vertical pump housing, and in particular to be a kind of vertical pump axle stretch end sealing knot
Structure.
Background technique
Most of pump housing is all that power support is provided by motor, and motor due to that can generate heat in use, usually all
Configure fan blade cooling structure.Most of pump housing is all to be arranged indoors in the prior art, so all not accounting for rain substantially
The seepage problem of axle stretch end when season is also all by the way of sealing ring is arranged substantially come real even if having in view of seepage problem
Existing, first sealing ring is bad using being easy for a period of time, needs to be replaced frequently, and has replacement troublesome and the high problem of replacement cost,
Once being likely to cause leak and and then damage motor without replacing in time；Second the setting of sealing ring can directly result in energy damage
Consumption.
In view of this, the applicant furthers investigate regarding to the issue above, there is this case generation then.
Utility model content
The main purpose of the utility model is to provide a kind of vertical pump axle stretch end sealing structures, can be directly in room
Outer application, and have the characteristics that long service life, without frictional dissipation and energy conservation.
In order to achieve the above objectives, the solution of the utility model is:
A kind of vertical pump axle stretch end sealing structure, for preventing gap and wind of the water flow outside shaft and motor between seat
Gap between leaf and shaft enters inside motor, is also formed with bearing between the shaft and the outer seat of motor；Wherein, described close
Seal structure has the fan blade being set in shaft section of stretching out and is supported on shaft end face and fan blade by screw fit sealing
Gasket, the fan blade formed using totally-enclosed face and covers the gap of shaft and motor outside between seat from top to bottom.
Further, the radius of the fan blade is greater than the radius of bearing between shaft and the outer seat of motor.
Further, the sealing structure further includes the annular water blocking boss being formed on the outer seat of motor, and the shaft is located at
The height of the ring-shaped inner part of annular water blocking boss, the annular water blocking boss is higher than the height of the outer seat upper surface of motor.
After adopting the above structure, the utility model relates to a kind of vertical pump axle stretch end sealing structures, first due to fan blade
It is formed using totally-enclosed face, so that the phenomenon that there is no leaks in the region covered；Second blocked using gasket fan blade and
Rainwater has been blocked in the outer of motor housing so when entire vertical pump is in upright state by the gap between shaft substantially
Portion.Further, in order to prevent there is the dip deviation in some angles in vertical pump during installation, in turn result in rainwater through electricity
Gap enters inside motor between the upper surface of the outer seat of machine and shaft and the outer seat of motor, is additionally provided with annular water blocking boss.
Compared with prior art, the utility model is realizing that a bit friction energy loss is completely absent when sealing loses, by
In not any wearing detail, therefore also has the characteristics that long service life.
Detailed description of the invention
Fig. 1 is that the utility model relates to a kind of schematic perspective views of vertical pump axle stretch end sealing structure.
Fig. 2 is the schematic diagram of the section structure of the utility model.
In figure: shaft 1；The outer seat 2 of motor；Annular water blocking boss 21；Upper surface 22；Bearing 3；Fan blade 4；Screw 41；Gasket
42。
Specific embodiment
In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into
Row elaborates.
As shown in Figure 1 to Figure 2, for the utility model relates to a kind of vertical pump axle stretch end sealing structure, for preventing
Gap of the sealing stream outside shaft 1 and motor between seat 2 enters inside motor, is also formed between the shaft 1 and the outer seat 2 of motor
There is bearing 3；The sealing structure has the fan blade 4 being set in 1 section of stretching out of shaft and is supported by 41 fit sealing of screw
Gasket 42 on 1 end face of shaft and fan blade 4, the fan blade 4 are formed using totally-enclosed face and cover 1 He of shaft from top to bottom
Gap between the outer seat 2 of motor.
In this way, the utility model relates to a kind of vertical pump axle stretch end sealing structures, first since fan blade 4 is using totally-enclosed
Face molding, so that the phenomenon that there is no leaks the region that is covered of fan blade 4；Second fan blade 4 is blocked using gasket 42 and is turned
Rainwater has been blocked in the outer of motor housing so when entire vertical pump is in upright state by the gap between axis 1 substantially
Portion.
In order to further prevent rainwater to enter inside motor, described 4 radius is greater than axis between shaft 1 and the outer seat 2 of motor
Hold 3 radius.Since the radius of bearing 3 is greater than the radius of shaft 1, described in this way 4 radius between seat 2 outside shaft 1 and motor
Much larger than the radius of the shaft 1.
As shown in Fig. 2, further, in order to prevent there is the dip deviation in some angles in vertical pump during installation,
Rainwater is in turn resulted in enter inside motor through gap between seat 2 outside the upper surface of seat 2 outside motor and shaft 1 and motor, it is described close
Seal structure further includes the annular water blocking boss 21 being formed on the outer seat 2 of motor, and the shaft 1 is located at the ring of annular water blocking boss 21
Inside shape, the height of the annular water blocking boss 21 is higher than the height of outer 2 upper surface 22 of seat of motor.In this way, the outer seat 2 of the motor
On ponding due to being kept out by annular water blocking boss 21, cannot be introduced into the gap between the shaft 1 and the outer seat 2 of motor
In.Closer, the annular water blocking boss 21 is completely covered the fan blade 4；It is deposited above water blocking boss 21 annular in this way
In keeping out for fan blade 4, rainwater can not enter from top；Ponding can not also enter to the shaft 1 and motor from side simultaneously
In gap between outer seat 2.
Compared with prior art, the utility model is realizing that a bit friction energy loss is completely absent when sealing loses, by
In not any wearing detail, therefore also has the characteristics that long service life.
The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field
The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
