Description

There is the immersible pump of axle envelope sand-prevention structure
Technical field
This utility model relates to a kind of immersible pump, particularly relates to a kind of immersible pump with axle envelope sand-prevention structure.
Background technology
As depicted in figs. 1 and 2, during immersible pump work, silt is likely to enter the annular seal space 3 of motor, causes sealing device 2 Damage, ultimately result in water and other foreign material invade motor cavity 1, cause electric pump cisco unity malfunction, Danger Electric shock risk, burn-down of electric motor etc. Serious adverse consequences, therefore, existing submersible pump installs rotary shaft lip seal 4 at motor-shaft extending, in lip-type packing 4 End is embedded in electric motor end cap outer end, utilizes lip 41 interference fit of rotating shaft 5 and rotary shaft lip seal 4, makes annular seal space 3 close Envelope, intercepts water and other foreign material invade motor cavity 1.
The material of rotating shaft 5 is 45 steel, and hardness is about HRA60, and surface roughness is 0.8Ra, when electric pump runs, and rotating shaft 5 High speed rotating, rotating shaft 5 mutually rubs with the lip 41 of rotary shaft lip seal 4, lip 41 He of rotary shaft lip seal Rotating shaft 5 has abrasion, the wear extent of rotating shaft 5 to be more than 10 times of rotary shaft lip seal lip 41 wear extent, after abrasion, and rotation Rotating shaft lip-type packing 4 and rotating shaft 5 are no longer interference fit, there is gap, cause the seal failure of annular seal space 3.
Draw through test, use the sand-prevention structure that rotary shaft lip seal 4 is formed with rotating shaft 5 interference fit, service life Life was less than 1000 hours, and after measures for sand prevention inefficacy, the service life of electric pump is 24 hours-500 hours, illustrated that axle seals sand-prevention structure Very big on impact in electric pump service life, through market survey with to reprocessing water pump statistical analysis, the electric pump quality accident of more than 30% with Bearing sealing failure is relevant, causes a large amount of economic loss.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above of prior art existence and provide one to have axle envelope sand prevention The immersible pump of structure, changes the sealing structure between rotating shaft and grease chamber's lid, makes to get rid of husky set and rotates together along with rotating shaft, makes to get rid of husky set Form sand prevention with sand prevention pad and seal structure, get rid of not exist between husky set and rotating shaft and relatively rotate, it is to avoid mutually wear and tear, when sand prevention is close When abrasion occurs in seal structure, change and get rid of husky set and anti-sand cushion, convenient maintenance and replacement, improve the service life of electric pump.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: have axle envelope sand-prevention structure Immersible pump, including motor, the rotating shaft being arranged on motor, one end of described rotating shaft passes the end cap of motor casing, described end cap And You Shigai is set between rotating shaft, it is characterised in that sand-prevention structure, described sand prevention are set between lid outer end, described grease chamber and rotating shaft Structure includes the anti-sand cushion being fixedly installed on lid outer end, grease chamber, fixing be nested with in rotating shaft get rid of husky set, described in get rid of the interior of husky set End is conflicted at the outer surface of described anti-sand cushion, and resistance surface between the two forms anti-Shamian Island.Change between rotating shaft and grease chamber's lid Seal structure, make to get rid of husky overlapping along with rotating shaft rotates together, make to get rid of husky set and form sand prevention sealing structure with sand prevention pad, get rid of husky set and turn Do not exist between axle and relatively rotate, it is to avoid mutually wear and tear.When sand prevention seals structure appearance abrasion, change and get rid of husky set and anti-sand cushion , convenient maintenance and replacement, improve the service life of electric pump.
As improving further and supplementing technique scheme, this utility model uses following technical measures: described Installation groove is set in rotating shaft, described in get rid of the outer wall interference fit of husky set outer end and described installation groove.The setting of groove is installed, Axial limiting can be carried out to getting rid of husky set, prevent water from the impact getting rid of husky set is occurred axial displacement.
Described sand set outer end of getting rid of coordinates a circlip for shaft, described circlip for shaft to be stuck in described installation groove. Circlip for shaft carries out axial limiting to getting rid of husky set further, prevents from throwing away.
The described sand set that gets rid of is for tubaeform.Tubaeform get rid of husky set when coordinating with anti-sand cushion, silt and foreign material can not only be blocked, Can also prevent from getting rid of husky set periphery accumulation by extrapolated for the foreign material such as silt, prevent getting rid of husky set and block.
Get rid of husky effect to improve, described in get rid of the horn mouth of husky set to extend out angle be 10 ° ~ 170 °.
The hardness of described anti-sand cushion is not less than HRA85, and surface roughness is 0.4Ra, and its material is pottery or alloy.Carry The hardness of high anti-sand cushion and flatness, reduce the degree of wear, improve the wearability of anti-sand cushion.
The outer of described anti-sand cushion outer surface arranges fixing groove, is nested with follower gasket circle, described follower gasket in described fixing groove Circle is fixed on described end cap by connector.Fixing anti-sand cushion that can be stable by fixing groove, pressing plate packing ring and connector, Make anti-sand cushion be fixed on firmly on end cap, do not rotated affected by getting rid of husky set.
This utility model has the advantages that
1, change the sealing structure between rotating shaft and grease chamber's lid, make to get rid of husky set and rotate together along with rotating shaft, make to get rid of Sha Taoyu Sand prevention pad forms sand prevention and seals structure, gets rid of not exist between husky set and rotating shaft and relatively rotates, it is to avoid mutually wear and tear, when sand prevention seals When abrasion occurs in structure, change and get rid of husky set and anti-sand cushion, convenient maintenance and replacement, improve the service life of electric pump.
2, get rid of between husky set and rotating shaft and form fixed installation, phase by interference fit, installation groove and circlip for shaft Do not exist between Hu and relatively rotate, it is to avoid mutually wear and tear.
3, improve hardness and the flatness of anti-sand cushion, reduce the degree of wear, improve the wearability of anti-sand cushion.
