Being capable of safe and reliable, stable operation.
To achieve the above object, the technical solution adopted in the utility model is as follows：A kind of marine high-pressure low temperature is proposed to dive
Liquid motor, including band wound stator iron core and cast-aluminum rotor in immersed pump, band wound stator is unshakable in one's determination to be included by stator
Stator core, stator coil, leader cable and the stator pressing ring and cramp positioned at stator core two ends that punching is overrided to form, institute
Stating band wound stator iron core integral coating has solvent-free epoxy dipping paints insulating barrier；Stator coil is using the wrapped burning of laminated film
Knot copper strap wire coiling, and low resin mica tape and alkali-free band are surrounded by outside it；Stator coil is tied up via dacron glass yarn rope
It is flush-mounted in stator slot after bundle, the leader cable of stator coil is polyvinyl fluoride insulated cable；Cast-aluminum rotor includes rotor iron
The heart and cage modle winding, rotor core are overrided to form by rotor punching, and cage type winding is made up of some aluminium cores and two end ring, aluminium core
It is flush-mounted in rotor slot, aluminium core is processed using commercial-purity aluminium.
The slot wedge of heelpiece, middle pad, adjusting pad and stator slot sealing part in the stator slot is using glass fibre laminated
Plate.
The stator punching, rotor punching are the 50W350 silicon steel plates of 0.5mm.
The utility model compared with prior art, the stator coil of motor using the wrapped sintering copper flat wire of laminated film around
System, draws and connects cryocable using polyvinyl fluoride insulated motor connecting flexible cable, heelpiece, middle pad, adjusting pad and groove in stator slot
Wedge uses laminate, and after rule is fully completed, band wound stator overall leaching non-solvent epoxy impregnating varnish unshakable in one's determination is twice so that whole
Also insulation stabilization can be reached when individual system is with -165 DEG C of cryogenic media LNG, LEG, LPG directly contacts.Meanwhile, the aluminium of cast-aluminum rotor
Core density is small, and rotor weight is greatly reduced, so as to mitigate main screw lift, meets that marine floating type is peculiar to vessel to be set well
Standby lightweight demand.In addition, the rotor punching material of the stator punching of stator core, cast-aluminum rotor selects low temperature resistant, height
Magnetic conduction, low-loss 0.5mm silicon steel plates 50W350, reduce motor iron loss, improve efficiency, reduce motor feels hot, from
And reduce the evaporating capacity of pumped (conveying) medium.
