Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
Consult Fig. 3 and Fig. 4, the embodiment that the utility model has the vertical pump of exhaust throwing disc comprises a motor 2, shaft seal unit 3, outer cover 4, and an impeller 5.
This motor 2 comprises a motor body 21, and one from this motor body 21 to the axle center 22 of downward-extension.
This shaft seal unit 3, comprises an axle sleeve group 31, throwing disc 32, shaft seal cover 33, and a fluid-tight circle 34.
This axle sleeve group 31 is set in this axle center 22, and has Upper shaft sleeve 311, Lower shaft sleeve 312 away from this motor body 21 of this motor body 21 of vicinity, and a set screw 313.This Upper shaft sleeve 311 has a joint 314 away from this motor body 21.This Lower shaft sleeve 312 embeds this joint 314 and is fixed on this Upper shaft sleeve 311.This set screw 313 enters this axle center 22 from the side screw lock of this Upper shaft sleeve 311, makes this Upper shaft sleeve 311 be fixed on this axle center 22.
This throwing disc 32 is arranged on the Upper shaft sleeve 311 of this axle sleeve group 31, and extends along this axle center 22 radial direction.In the present embodiment, this throwing disc 32 manufactures in one piece with this Upper shaft sleeve 311.
This shaft seal cover 33 is arranged on this motor body 21, and is passed by this axle sleeve group 31, and and there is a gap 331 between this axle sleeve group 31.This shaft seal cover 33 has a lid shell 332 and a closed loop 333.This lid shell 332 is arranged on this motor body 21 and covers this throwing disc 32, and has the perforation 334 that this axle sleeve group 31 of a confession passes, at least one runner 335 being positioned at side.This runner 335 is communicated with this gap 331.In the present embodiment, the lid shell 332 of this shaft seal cover 33 has the runner 335 that two are positioned at two opposition sides, and, the contiguous described runner 335 of outer periphery of this throwing disc 32.
This closed loop 333 to be arranged on outside this lid shell 332 and around this perforation 334.In the present embodiment, this closed loop 333 is ceramic rings.
This fluid-tight circle 34 is positioned at the outside of this shaft seal cover 33, and is set in the Upper shaft sleeve 311 of this axle sleeve group 31, and has a flexible lip 341.This lip 341 can abut against the closed loop 333 in this shaft seal cover 33, and closes the gap 331 of this shaft seal cover 33.
This outer cover 4 comprises cover body 41, bailing outlet 42 away from this motor body 21 that covers this shaft seal unit 3, and at least one connects inside this this cover body 41 logical and the relief opening 43 in outside.In the present embodiment, this outer cover 4 comprises four relief openings 43, and described relief opening 43 is one group with every two, lays respectively at two opposition sides of this cover body 41, and is communicated with the gap 331 of this shaft seal cover 33 by described runner 335.
This impeller 5 is arranged on this axle center 22 end and connects with the Lower shaft sleeve 312 of this axle sleeve group 31, and is positioned at the bailing outlet 42 of this outer cover 4.When this motor body 21 starts, this impeller 5 can rotarily drive by this axle center 22, and rotates in this bailing outlet 42 and draw water.
Close this motor body 21 and make it remain static, this fluid-tight circle 34 can abut against mutually with this closed loop 333, and then closes the gap 331 of this shaft seal cover 33, therefore, corrosive gas in liquid is subject to the stop of this fluid-tight circle 34, cannot enter this motor body 21 inside and be corroded.
Consult Fig. 5, start this motor body 21 and make it be in operating condition, this axle center 22 rotarily drives this axle sleeve group 31 and this fluid-tight circle 34 rotates, make the lip 341 of this fluid-tight circle 34 by the impact of centrifugal force away from this closed loop 333, now, corrosive gas via path II as shown in Figure 5, can enter this lid shell 332 via this gap 331, and flow out from the runner 335 of this lid shell 332 by rotarily driving of this throwing disc 32, and discharged by the relief opening 43 of this outer cover 4.Discharge corrosive gas by the way, can avoid contacting with this motor body 21 and making it damage.
It is worth mentioning that, this throwing disc 32 has multiple rib (not shown).Described rib is formed at the side away from this motor body 21 at intervals.Described rib can promote the usefulness of this throwing disc 32 exhaust, and corrosive gas is efficiently discharged from described relief opening 43.
In sum, this throwing disc 32 can rotarily driving by this axle center 22, order about the corrosive gas being positioned at this outer cover 4 to discharge from described relief opening 43, avoid this motor body 21 contact with corrosive gas and damage, so really can the purpose of this utility model be reached.
