Abstract
The utility model discloses a vertical type motor for screw pump, comprising a shell, a stator, a rotor and a rotor shaft. The rotor shaft is of a hollow structure, a power polished rod passes through the inner chamber of the rotor shaft in a coaxial line driven way. A fan mechanism of the shell is provided a supporting frame for the purpose of connection. The utility model has a compact structure and a beautiful and elegant installation appearance, solves the problems of overweight and over-abrasion and is applied to oil exploitation technique with a screw pump.
Description
One, technical field
The utility model relates to motor, particularly a kind of ground driving screw pump vertical type motor.
Two, background technology
Existing ground driving screw pump motor is a solid shafting, and side is installed on the reduction box side, but it has the problem of existence to be:
1, because axiality is not enough and the existence of eccentric weight, well head is rocked seriously, especially in big discharge capacity, take out under the situation of well deeply, motor house power strengthens, and faster rotational speed is rocked all the more seriously, rocks greatly more, gets over easy damaged equipment;
2, owing to rock, the well head seal box is easy to damage, causes environmental pollution;
3, because biasing is installed, during installation the axle center difficulty is strengthened, potential safety hazard is just more outstanding.
Three, summary of the invention
That the technical problems to be solved in the utility model provides is that a kind of hollow, vertical, coaxial line is installed, do not have rock, safe and reliable screw pump vertical type motor.
The technical scheme that the utility model is dealt with problems is the screw pump vertical machine that comprises housing, rotor, stator and armature spindle, and described armature spindle is a hollow-core construction, and the power polished rod passes this armature spindle inner chamber, is the coaxial line type of drive; The fan place of described housing installs the connection bracing frame, connects anti-reverse mechanism on this bracing frame.
Wherein, the link of described armature spindle is to be suitable for the concave-convex structure that other mechanism is connected.
Wherein, the support frame as described above upper end is connected with anti-reverse mechanism, and the lower end is provided with the dividing plate of band mesopore, and armature spindle passes this hole, installs bearing on this armature spindle and this dividing plate.
The utility model has following advantage or beneficial effect compared with prior art:
1, owing to adopted hollow shaft and vertical installation, forms the coaxial line driving, therefore do not had and lay particular stress on phenomenon, also just alleviated rocking of well head, the life cycle that has prolonged equipment greatly;
2, adopt shaft coupling to connect, the transmission efficiency height, safe and reliable, maintenance is installed conveniently;
3, adopt vertical installation axis drives, complete machine stability is good, and motor power (output), design torque are unrestricted, loses for a short time, and noise is low, and operating cost is low, efficient energy-saving;
4, whole machine installation is convenient, and elegant in appearance, theftproof performance is good, is suitable for management.
Four, description of drawings
Fig. 1 is the utility model mounting structure schematic diagram;
Fig. 2 is the utility model electric motor structure schematic diagram.
Five, embodiment
Referring to Fig. 1-Fig. 2, a kind of screw pump vertical type motor, comprise housing 70, stator 67, rotor 66 and armature spindle 68, described armature spindle 68 is a hollow-core construction, power polished rod 1 passes this armature spindle 68 inner chambers, be the coaxial line type of drive, install connection bracing frame 61 on fan 62,63 end faces of described housing 70, connect anti-reverse mechanism 4 on this bracing frame 61.
Armature spindle 68 of the present utility model is the concave-convex structure with the link of anti-reverse mechanism 4, is connected by shaft coupling; Support frame as described above 61 upper ends are connected with anti-reverse mechanism 4 bottoms, and the lower end is provided with the dividing plate of band mesopore, and armature spindle 68 passes this dividing plate mesopore, install bearing 64 on this armature spindle 68 and this dividing plate.Fan 62,63 is installed in the upper end of this armature spindle 68, and rotor 66 is installed on the armature spindle 68, outside the rotor and on the housing 70 stator 67 is installed, and lower flange 71 is installed in housing 70 bottoms, and lower bearing 69 is installed in lower flange 71 and armature spindle 68 lower ends.
Overall structure of the present utility model is installed as shown in Figure 1, and motor 6 bottoms connect well head flow tee 7, and these flow tee 7 inner chambers are installed polished rod seal box 8; Motor 6 tops connect anti-reverse mechanism 4 and reduction box 3 successively, and the hollow rotor shafts 68 that power polished rod 1 passes motor 6 is connected by square clamp 2 with the hollow shaft of gearbox 3 on gearbox 3 tops, fixes.
Claims (3)
1, a kind of screw pump vertical type motor, comprise housing, stator, rotor and armature spindle, it is characterized in that described armature spindle is a hollow-core construction, the power polished rod passes this armature spindle inner chamber, be the coaxial line type of drive, the fan end face of described housing is installed the connection bracing frame.
