Abstract
The utility model provides a driving device of a side driving type reverse rotation preventing screw pump and aims at solving the problem that when a screw pump oil drilling system is at a stop state, elastic deformation potential energy stored in a roofbolt is rapidly released, the roofbolt rotates reversely and severe damage can be caused. The key point of the technical scheme is that a three-phase motor and a reduction box are fixed together; the output shaft of the three-phase motor is connected with the reducing mechanism of the reduction box; the output shaft of the reduction box, the rotation number of which is reduced through the reducing mechanism, is connected with the output shaft of the screw pump; an oil box flange is arranged below the reduction box; an electromagnetic brake device is arranged at the rear end of the main shaft of the three-phase motor. The driving device of the side driving type reverse rotation preventing screw pump has the positive effect that the reverse rotation preventing requirement of the screw pump is realized by using snub function of a power losing brake and the fracture of a belt due to connection of the motor and the belt and skidding fault are avoided.
Description
Technical field
The utility model belongs to oil field equipment technical field, is that the side with the anti-reverse equipment of electromagnetism that petroleum production is carried out for drive screw pump in a kind of oil field is driven formula reverse turning-proof screw pump drive device specifically.
Background technique
Along with scientific and technological development and social progress, oil has become a requisite part in human society, and its various goods that are derived are all being played the part of important role in people's life.Along with the continuous increase of society to oil demand, also need to raise the efficiency, make recovery process safer for the equipment of recover petroleum accordingly.
In existing oil extraction in oil field system, screw pump is by a large amount of application, and screw pump is installed under oil well, 1000 meters of left and right apart from ground, driving unit on screw pump is installed on ground, and drive unit drive sucker rod rotary drive screw pump work is the oil pipeline to ground by petroleum pump.
The technical problem that general screw pump drive exists is at present as follows:
At work, the working speed of screw pump is 120 revs/min of left and right, and conventional three phase electric machine rotating speed is more than 1000 revs/min, conventionally will use speed reducer speed governing; While work in the winter time for the belt being connected between three phase electric machine and speed reducer, because temperature is low, belt occurs skidding and throws switch, and affects screw pump and normally works, and this structure also takies a large amount of spaces.
In the time recovering the oil, screw pump oil production system is shut down under the state of (or power supply system power-off), and the resiliently deformable potential energy being stored in roofbolt can quick release make roofbolt reversion, can cause serious harm.Therefore screw pump drive system must install anti-reverse system additional.Existing anti-reverse mechanism adopts ratchet braking, utilize ratchet that rotating shaft is stuck, but the energy in screw rod can not discharge in the time there is reversion; Will sudden outburst when the energy in when maintenance screw rod, moment produces huge moment of torsion, and roofbolt is reversed fast.Often cause the reversion roofbolt of screw pump to thread off, polished rod get rid of curved, damage the situation such as surface drive, even injure on-the-spot staff.
Summary of the invention
The purpose of this utility model is to provide the side with the anti-reverse equipment of electromagnetism of carrying out petroleum production for drive screw pump in a kind of oil field and drives formula reverse turning-proof screw pump drive device.
The technical solution of the utility model is: three phase electric machine and speed reducer are fixed together, the output shaft of three phase electric machine is connected with the reducing gear of speed reducer, the reduction gearbox output shaft reducing after revolution by reducing gear is connected with screw pump output shaft, speed reducer below is provided with oil box flange, and the rear-end of spindle of three phase electric machine is provided with electromagnetic brake device; Described electromagnetic brake device comprises: be arranged on friction disk and the hub splines of the rear-end of spindle of three phase electric machine, friction disk top is provided with armature, is fixed with brake spring on armature, and brake spring and electromagnetic coil are all arranged in housing.
Top on the main shaft of three phase electric machine is provided with fan.
The beneficial effects of the utility model are that it utilizes the point of the power-off brake function of stopping to realize the anti-reverse requirement of screw pump, and have cancelled motor and be connected with belt and cause belt fracture and sipping fault.The utlity model has compact appearance, save manufacture cost, winter operation is stable not to throw switch, and band electromagnetic brake device can slowly discharge screw rod elastic potential energy by control system control electromagnetic brake device in the time of system-down, thereby ensures safety.The features such as it is high that the utility model also has control progress, reliable and stable, and practicability is stronger.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A portion enlarged view of Fig. 1.
Model utility is described in further detail by example below in conjunction with accompanying drawing; but following example is only the utility model example wherein; do not represent the rights protection scope that the utility model limits, rights protection scope of the present utility model is as the criterion with claim.
Embodiment
Referring to Fig. 1, three phase electric machine 2 is fixed together with speed reducer 3, the output shaft of three phase electric machine is connected with the reducing gear of speed reducer, the reduction gearbox output shaft reducing after revolution by reducing gear is connected with screw pump output shaft 4, speed reducer below is provided with oil box flange 5, and the rear-end of spindle of three phase electric machine is provided with electromagnetic brake device 1.
Referring to Fig. 2, described electromagnetic brake device comprises: the friction disk 16 and the hub splines 18 that are arranged on main shaft 11 rear ends of three phase electric machine, friction disk top is provided with armature 15, is fixed with brake spring 14 on armature, and brake spring and electromagnetic coil 13 are all arranged in housing.
Top on the main shaft of three phase electric machine is provided with fan 12.
Working principle of the present utility model and advantage are as follows:
At work oil box flange is installed on to binding on device of ground petroleum pipeline, sucker rod is through seal shaft, be fixedly connected with output shaft by square clamp, three phase electric machine revolution nearly 1000 turns, decelerate to by gear reduction box the rotating speed that screw pump needs, the rotation of drive output shaft, and then drive screw pump work by sucker rod.
The working procedure of electromagnetic brake device when normal work: external circuit control electromagnetic coil obtains electric, makes armature adhesive, compression brake spring, friction disk rotates with motor shaft by hub splines, thereby does not affect the normal operation of motor.
Because adopt gear-box to slow down, ensure the stable of speed ratio, in the winter time also can stable operation, there is not the problem of throwing switch, also make this structure compacter, reduce and take up an area space, cost-saving.
In the time of system-down, external circuit control electromagnetic coil dead electricity, thereby release armature, under the effect of brake spring, make armature and fastening flange clamp friction disk, by hub splines by motor shaft locking, thereby sucker rod is stopped operating, through the intermittence of some seconds, external circuit control electromagnetic coil obtains electric, sucker rod can be rotated, through the releasing course of some seconds, again control electromagnetic coil dead electricity, sucker rod is stopped operating, because the time discharging is shorter, sucker rod just rotates, just again by locking, can not cause danger, through some above-mentioned work cycle, elastic potential energy in sucker rod is just by dischargeing progressively, ensure safety.
