Description
Technical field
The present invention relates to a kind of submersible motor, it includes casing, stator, rotor and sealing device.
Background technology
The structure of submersible motor generally comprises casing, stator, rotor and sealing device, is quiet between its casing and end cap
Sealing structure is connected, and because the main shaft of rotor will stretch out from end cap, movable sealing structure, i.e. main shaft is taken between rotor and end cap
Sealing ring is provided between end cap, sealing property can decline after sealing ring is worn, water can enter stator winding, make stator around
Group insulating properties reduction, so as to electric leakage or winding coil short circuit occur.It is therefore desirable to be improved.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of submersible motor, and the submersible motor can effectively prevent water from entering
Stator winding.
The present invention solve technical problem technical scheme be：A kind of submersible motor, it includes casing 1, is pressed into casing
Stator 2, insert rotor 3 in the stator, left end cap 4 is connected with casing, and right end cap 5 is to be integrally formed with casing, water-proof cable
11 sealingly extend through right end cap is connected with the lead of stator winding, and the left end of the main shaft 7 of rotor stretches out from left end cap, main shaft
Right-hand member does not expose in being inserted in right end cap from right end cap, and the two ends of main shaft pass through clutch shaft bearing 8 and second bearing respectively（8’）
Supporting, it is characterized in that, sealing shroud is provided with the air gap between stator and rotor, there is the left end of sealing shroud the dorsad center of circle to prolong
The flange stretched, the right-hand member of sealing shroud has the flange extended towards the center of circle, and the flange of sealing shroud left end is pressed on machine by left end cap
On shell, flange and the right end cap of sealing shroud right-hand member are tightly connected, the length of the wall thickness less than air gap of the sleeve body portion of sealing shroud.
It is a feature of the present invention that right end cap is integrally formed with casing, flange and the right end cap of sealing shroud right-hand member are tightly connected,
The flange of sealing shroud left end is connected with casing sealing, and sealing shroud separates stator and water, effectively maintains the exhausted of stator winding
Edge performance.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Accompanying drawing mark is represented respectively：1- casings, 2- stators, 3- rotors, 4- left end caps, 5- right end caps, 6- sealing shrouds, 7- master
Axle, 8- bearings, 9- sealing rings, 10- water joints, 11- water-proof cables, 12- bearing chambers, 13- projections.
Specific embodiment
In conjunction with brief description of the drawings specific embodiment of the invention.
A kind of submersible motor, it includes casing 1, the stator 2 being ordinatedly pressed into casing, slotting rotor 3 in the stator, left
End cap 4 is connected with casing, and right end cap 5 is to be integrally formed with casing.
Right end cap is provided with water joint, and the lead of stator winding is by the water joint 10 that is sealingly disposed on right end cap
It is connected with water-proof cable 11；Water-proof cable also can be directly through right end cap, the contact portion epoxy of water-proof cable and right end cap
Resin seal.
Clutch shaft bearing room 12 is provided with left end cap, clutch shaft bearing 8, a left side for the main shaft 7 of rotor are provided with clutch shaft bearing room
End is stretched out from clutch shaft bearing；Second bearing room 12 ', the right-hand member closing of second bearing room, second bearing are provided with right end cap
Second bearing 8 ' is provided with room, the left end of main shaft 7 is inserted in second bearing.
Sealing shroud is provided with air gap between stator and rotor, the left end of sealing shroud has the convex of dorsad center of circle extension
Edge, the right-hand member of sealing shroud has the flange extended towards the center of circle, and the flange of sealing shroud left end is existed by left end cap by bolt presses
On the left side of casing.
The flange of sealing shroud right-hand member is tightly connected by flange and bolt with right end cap, and described bolt can be by nut
Tighten, fluid sealant is scribbled between bolts and nuts；To improve sealing property, a projection can be also extended outward on right end cap
13, bolt is spun in projection.
The wall thickness of the sleeve body portion of sealing shroud is less than the length of air gap, without friction and sealing shroud between when rotor is rotated.It is close
Big envelope closes stator, and when being intake in motor, the insulating properties of stator winding are unaffected.Because sealing shroud will not be ground
Damage, therefore can reliably keep stator winding to dry.
The water inlet position of this submersible motor is clutch shaft bearing room, and the particulate matter in water can be formed to bearing and worn and torn, and be anti-
Only bearing is worn, and sealing ring 9 is provided between the oral area and main shaft of clutch shaft bearing room, to stop that particulate matter material enters axle
In holding, the sealing property of motor is also improved in addition.
