Abstract
The utility model discloses a hydraulic anti-reversion mechanism matched with a screw pump permanent magnet anti-reversion direct-drive type driving device. According to the hydraulic anti-reversion mechanism, a shell body of a permanent magnet anti-reversion motor is additionally provided with an installation plate. The installation plate is provided with a brake caliper and a hydraulic station. A hydraulic oil pump is installed in the hydraulic station. The top of the hydraulic station is provided with a gear fixing frame. A gear brake disc is fixed on a main shaft torsion transferring sleeve of a screw pump, wherein one side of the gear brake disc is embedded in the brake caliper, and the other side of the gear brake disc is meshed with a small gear. An overrunning clutch is arranged between the small gear and an oil pump transmission shaft. The hydraulic anti-reversion mechanism has the advantages that when the reversion speed of the screw pump is high or when reversion torsion is great, the two sets of brake devices can be simultaneously automatically put into operation, and the reversion torsion of the screw rod can be guaranteed to be safely, reliably and simultaneously released by the driving device; and under the condition of complete failure of permanent magnet anti-reversion, the hydraulic anti-reversion device can independently brake reversion and release torsion.
Description
Technical field
The utility model relates to the supporting hydraulic pressure anti-reverse mechanism of the anti-reverse directly driving type drive unit of a kind of screw pump permanent magnetism, and this mechanism is suitable on the anti-reverse directly driving type drive unit of the permanent magnetism of screw pump, installing additional.
Background technique
Observe through long-term oil field practice application, the anti-reverse drive unit that directly drives of existing screw pump permanent magnetism exists following significant problem, and the one, when faults such as screw pump generation holddown, the electric current of motor can be multiplied, thereby causes moment of torsion increase at double.When motor is compeled stall because of moment of torsion oversteps the extreme limit; The huge reverse torque of having put aside in screw pump can be with high rotating speed pushing motor counter-rotating; At this moment can cause the total failure of permanent magnetism braking, thereby cause taking off bar, the generation of drive unit damage and even great human injury.The 2nd, because other apparatus failure, control section fails when screw pump orders about the drive unit counter-rotating adds and load also can cause the anti-reverse inefficacy of permanent magnetism, and these have all constituted serious threat to the safety of recovering the oil.
Summary of the invention
The goal of the invention of the utility model is to provide the anti-reverse directly driving type drive unit of a kind of screw pump permanent magnetism supporting hydraulic pressure anti-reverse mechanism, and this mechanism can replenish the various defectives of existing permanent magnet direct-drive drive unit, guarantees the security of operation of screw pump.
The technological scheme of the utility model is: this mechanism comprises the anti-reverse directly driving type drive unit of the permanent magnetism of screw pump; On the housing of the anti-reverse motor of this device permanent magnetism, install a mounting plate additional through bolt; A side is equipped with fitting seat on mounting plate; Opposite side is equipped with hydraulic station, and brake calipers is housed on the fitting seat, and brake calipers is furnished with brake cylinder.Hydraulic-pressure pump is housed in the hydraulic station, and hydraulic-pressure pump is connected with the brake cylinder of brake calipers through the oil circuit pipeline that has throttle valve or throttle orifice, at the top of hydraulic station the gear fixing frame is housed.
The main shaft torsion transmission that the gear brake disc is fixed on drive unit puts, and a side of gear brake disc is set in the brake calipers, opposite side and pinion, and small gear is contained in the gear fixing frame, between small gear and oil pump drive spindle, free wheel device is housed.Be suitable for the mounting hole that on dissimilar drive units, installs additional also can being provided with on the described mounting plate.
The beneficial effect of the utility model is: install the hydraulic pressure anti-reverse mechanism on the drive unit additional anti-reverse directly the driving of permanent magnetism, can make the more safe and reliable operation of whole device.When the counter-rotating of screw pump high; Two cover braking device can put into operation simultaneously automatically when reverse torque was very big; Can guarantee that drive unit can accomplish safe and reliable synchronous release with the reverse torque of screw pump, until drive unit with the whole safe releases of the reverse torque of screw pump.Hydraulic pressure anti-reverse mechanism also can independently the reverse braking and the release of moment of torsion under the situation of the anti-reverse total failure of permanent magnetism.

Embodiment
Example 1
As shown in Figure 1; This mechanism comprises the anti-reverse directly driving type drive unit of the permanent magnetism of screw pump; On the housing of the anti-reverse motor of this device permanent magnetism, install a mounting plate 7 additional through bolt, a side is equipped with fitting seat on mounting plate 7, and opposite side is equipped with hydraulic station 5; Brake calipers 1 is housed on the fitting seat, and brake calipers 1 is furnished with brake cylinder.In the hydraulic station 5 hydraulic-pressure pump is housed, hydraulic-pressure pump is connected with the brake cylinder of brake calipers 1 through the oil circuit pipeline that has throttle valve or throttle orifice, at the top of hydraulic station 5 gear fixing frame 3 is housed.
Example 2
The working principle of the utility model is to be small gear 8 transmitting torques through gear brake disc 2, and when drive unit was just being become a full member normal work, free wheel device 4 was thrown off, and a whole set of hydraulic system is not worked.When drive unit reversed, free wheel device 4 was started working, and at this moment gear brake disc 2 drives small gear 8; Drive the hydraulic-pressure pump rotation of hydraulic station 5 through free wheel device 4; The fuel feeding of hydraulic-pressure pump raises the brake cylinder pressure of brake calipers 1, and brake calipers 1 begins braking, and the speed of counter-rotating is fast more; The amount of the fuel feeding of hydraulic-pressure pump is big more, and the moment of torsion of braking is big more.When the speed drop of counter-rotating gets off, fuel delivery is also along with reduction, the pressure of brake calipers 1 since the shunting action of throttle valve also along with decline, the drive unit counter-rotating begins again to accelerate, brake calipers 1 begins braking again.Such action repeats repeatedly repeatedly, and drive unit just can discharge the reverse torque of screw pump fully.All anti-reverse devices of hydraulic pressure all are installed on the anti-reverse mounting plate of hydraulic pressure 7.Mounting plate 7 is furnished with the mounting hole of different size, can be contained on the drive unit of different manufacturers.
