Description
Technical field
The utility model relates to machine field, is specifically related to a kind of totally-enclosed oil-well rig top and drives variable-frequency motor.
Background technology
Oil field drill limited space, require that top-drive motor power is large, volume is little, the product structure of domestic and international electrical machinery plant of the same trade is mostly open type, good heat dissipation, exert oneself large, but it is poor to protect, the heart of motor--winding directly contacts with outside air, be difficult to reach waterproof, moistureproof, anticorrosion, the ability of sand-proof, be difficult to meet the severe operating mode of oil field drill, easily occur in using that electrical machine insulation damages, burn-down of electric motor phenomenon, reduce the reliability of motor, particularly offshore oil rig, motor is more needed to have good protection against the tide, anti-corrosion function, therefore in the urgent need to meeting under property indices and the large prerequisite of installation dimension, solve the protection question of motor.
Summary of the invention
The utility model object provides a kind of totally-enclosed oil-well rig top to drive variable-frequency motor, the deficiency solved the problem, and meets the demand of the sector.
The utility model is achieved in the following ways a kind of totally-enclosed oil-well rig top and drives variable-frequency motor, comprise stator frame and the stator being fixed on stator frame inside, and the rotor be rotatably mounted in stator, rotor comprises armature spindle, armature spindle is provided with rotor end ring, rotor bar is fixed on rotor end ring, rotor air channel is provided with between armature spindle and rotor bar, the left end of armature spindle is fixed wtih internal fan, internal fan copper rotor axle can together rotate, when internal fan rotates, air is moved right by rotor air channel, the left side of internal fan is provided with stator end cap, stator end cap is bolted on stator frame, form closing of a left side, stator frame is fixed on enclosure, then be fixed between stator on stator frame and shell and be provided with stator air channel, end cap is bolted on the left end of shell, and the right-hand member of shell is fixed with blower fan, blower fan carries out rotating air driven, along stator air channel to left movement.
Described case surface pastes aluminum alloy heat sink, and hot-air, through stator air channel, will be touched shell, be dispelled the heat by heat by aluminum alloy heat sink; Sealing ring is provided with between described end cap and armature spindle.
The beneficial effects of the utility model be when meet the motor feels hot and volume requirement, totally enclosed machine will be converted to by open-type electric machine in the past, and installation dimension is consistent with domestic and international motor, motor winding is totally-enclosed, be hedged off from the outer world, there is good waterproof, protection against the tide, anticorrosion, sand-proof ability, greatly improve the protective of motor, reliability.
Accompanying drawing explanation
Fig. 1 is that entirety partly cuts open figure;
As described in Figure 1, stator frame (1), stator (2), rotor (3), armature spindle (4), rotor end ring (5), rotor bar (6), internal fan (7), rotor air channel (8), stator end cap (9), shell (10), stator air channel (11), end cap (12), blower fan (13), sealing ring (14).
Embodiment
Variable-frequency motor is driven on a kind of totally-enclosed oil-well rig top, comprise stator frame and the stator being fixed on stator frame inside, and the rotor be rotatably mounted in stator, rotor comprises armature spindle, armature spindle is provided with rotor end ring, rotor bar is fixed on rotor end ring, rotor air channel is provided with between armature spindle and rotor bar, the left end of armature spindle is fixed wtih internal fan, internal fan copper rotor axle can together rotate, when internal fan rotates, air is moved right by rotor air channel, the left side of internal fan is provided with stator end cap, stator end cap is bolted on stator frame, form closing of a left side, stator frame is fixed on enclosure, then be fixed between stator on stator frame and shell and be provided with stator air channel, end cap is bolted on the left end of shell, and the right-hand member of shell is fixed with blower fan, blower fan carries out rotating air driven, along stator air channel to left movement.
Described case surface pastes aluminum alloy heat sink, and hot-air, through stator air channel, will be touched shell, be dispelled the heat by heat by aluminum alloy heat sink; Sealing ring is provided with between described end cap and armature spindle.
Operation principle: when rotor rotates, internal fan on armature spindle just and then together rotates, air now can be driven to move right from rotor air channel, heat is produced because rotor rotates, the air that heat moves thereupon moves right, when hot-air moves to right-hand member, blower fan rotates and hot-air is blowed to left, now internal fan and blower fan produce convection current, so hot-air will to the stator duct flows on both sides, when hot-air is from stator duct flows, and send heat to shell with housing contacts, shell is being dispelled the heat by the aluminium alloy be pasted onto on shell.
