Description
Technical field:
The utility model relates to oil extraction in oil field field of mechanical technique, is specifically related to the anti-reverse automatic controller of a kind of driving unit on screw pump.
Background technique:
Current screw bolt well ground driving arrangement mainly contains normal bias formula drive unit and motor direct-drive device two kinds, following problem is also there is: one is control can not ensure to be perfectly safe in roofbolt reversion in application process, ratchet wheel pawl type anti-reverse mechanism needs artificially to discharge moment of torsion on the ground, and risk factor is high; And although hydraulic reverse turning-proof and electromagnetism dynamic braking anti-reverse mechanism can discharge moment of torsion automatically, also there is probability out of control, polished rod and square clamp high-speed rotary on ground installation is transferred from a team to another and is brought larger security risk; Two is that maintainability cost is higher, and offset drive unit utilizes belt pulley and speed reducer to carry out transmitting torque, and transmission part is many, cause operational efficiency low, later maintenance workload is large, and motor direct-drive device adopts magneto Direct driver, the cost of magneto is high, and there is the risk of demagnetization.
Model utility content:
In order to overcome the deficiency of background technique, the utility model provides a kind of driving unit on screw pump anti-reverse automatic controller.This device is placed between motor and well head, thus realizes the rotating speed automatically controlling screw rod reversion under the condition controlled without any external force.This device has that structure is simple, low cost of manufacture, safe and reliable, maintenance cost is low, completely without the need to features such as manual operations.
The technical solution of the utility model is: the anti-reverse automatic controller of this driving unit on screw pump, comprise support, support is by support lower flange, support upper flange and cradling piece composition, described support lower flange is installed on blowout preventer, support lower flange is provided with thrust-bearing overrunning clutch and magnetic conductive disk successively, overrunning clutch is fixedly connected with magnetic conductive disk, hollow shaft lower end in overrunning clutch center hole is positioned at support lower flange, its upper end is connected with polished rod by expansion sleeve, in magnetic conductive disk, permanent magnetic disk is installed, gap is provided with and magnetic conductive disk can rotate around permanent magnetic disk between magnetic conductive disk and permanent magnetic disk, permanent magnetic disk is fixedly connected with support upper flange by adpting flange, support upper flange is provided with direct driving motor.
The utility model has following beneficial effect: existing anti-reverse mechanism replaced by the anti-reverse automatic controller of this novel employing driving unit on screw pump, compared with former anti-reverse mechanism, the sharpest edges that the anti-reverse automatic controller of driving unit on screw pump has are exactly in the process of screw rod reversion, it realizes the rotating speed limiting screw rod under the condition not needing extraneous any power, so just completely avoid hydraulic pressure and the electromagnetism anti-reverse mechanism situation that it regulates the effect of reverse to lose efficacy when exterior power disappears, self-regulating rotary speed can be realized completely.
Because the anti-reverse automatic controller of driving unit on screw pump is when work, it is also rotating along with polished rod, thus release the energy stored in screw rod, it is such that such benefit is that of avoiding similar pawl type brake devices, need the situation of artificial release moment of torsion, and then avoid secondary injury is caused to the person, improve the Security of directly-driven screw pump.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
1. direct driving motors in figure; 2. adpting flange; 3. support upper flange; 4. permanent magnetic disk; 5. magnetic conductive disk; 6. support lower flange; 7. blowout preventer; 8. polished rod; 9. expansion sleeve; 10. overrunning clutch; 11. thrust-bearings; 12. cradling pieces; 13. hollow shafts.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the anti-reverse automatic controller of this driving unit on screw pump comprises support, support is made up of support lower flange 6, support upper flange 3 and cradling piece 12, described support lower flange 6 is fixedly installed on blowout preventer 7, support lower flange 6 is provided with successively thrust-bearing 11, overrunning clutch 10 and magnetic conductive disk 5, overrunning clutch 10 is fixedly connected with magnetic conductive disk 5, and this structure improves the radiating effect of product, thus extends the life-span of product.In overrunning clutch 10 center hole hollow shaft 13 lower end is positioned at support lower flange 6, its upper end is connected with polished rod 8 by expansion sleeve 9, hollow shaft 13 and overrunning clutch 10 are fixed as one, during motor reversal, hollow shaft 13 rotates with polished rod 8, permanent magnetic disk 4 is installed in magnetic conductive disk 5, gap is provided with and magnetic conductive disk 5 can rotate around permanent magnetic disk 4 between magnetic conductive disk 5 and permanent magnetic disk 4, permanent magnetic disk 4 is fixedly connected with support upper flange 3 by adpting flange 2, and support upper flange 3 is provided with direct driving motor 1.
When motor rotates forward (screw pump normally works): polished rod 8 rotates with the rotation of motor shaft, and now overrunning clutch 10 does not work, magnetic conductive disk 5 and permanent magnetic disk 4 do not rotate.Now be equivalent to the anti-reverse automatic controller of driving unit on screw pump is not installed.
Time motor reversal (shutting down suddenly or power-off): polished rod 8 reverses because residual stress produces inertia; under the effect of overrunning clutch 10; magnetic conductive disk 5 is with the same in the same way rotational speed of polished rod 8; now namely magnetic conductive disk 5 starts the magnetic line of force cutting magnetic field of permanent magnet; induction field is produced in magnetic conductive disk 5; induction field and permanent magnetic field 4 interact; produce the power that permanent magnetic disk 4 is rotated; but can not rotate because permanent magnetic disk 4 is fixed on support, the form with heat is dispersed in air by induction field and the permanent magnetic field energy produced that interacts.Permanent magnetic disk 4 also produces to magnetic conductive disk 5 power that one is hindered its rotation simultaneously, thus limit the rotational velocity of polished rod 8, due to polished rod 8 rotating speed and the size of power hindering magnetic conductive disk to rotate and some linear, thus reach the object of adjustment polished rod speed reversal automatically.Achieve under the condition driven without any external impetus, the rotating speed of screw rod reversion is controlled automatically, and then prevents the generation of driving and other security incidents.
Because the anti-reverse automatic controller of driving unit on screw pump itself is without any need for power, save the energy, structure is simple so this equipment has, low cost of manufacture, safe and reliable, maintenance cost is low, completely without the need to manual operation, the various features such as energy-conservation.
