Abstract
An oil pumping system of a direct drive type permanent-magnet synchronous motor is mainly composed of a screw pump connector 1, a blowout preventer 2, a permanent magnet motor body 3, a control cabinet 4, a seal 5, a drive plate 6, a protective cover 7 and a screw pump rotary rod 8. After the blowout preventer 2 is connected and fastened with the permanent magnet motor body 3, the blowout preventer 2 penetrates through the screw pump rotary rod 8, and the blowout preventer 2 and the screw pump connector 1 are mounted and are connected and fastened. The seal 5 is arranged at the shaft end of the permanent magnet motor body 3, the seal 5 and the shaft end of the permanent magnet motor body 3 are tightly pressed through the drive plate 6, and the seal 5 is connected and fastened with the screw pump rotary rod 8. The control cabinet 4 is arranged near the permanent magnet motor body 3. After a power supply is switched on, currents can be transmitted to the permanent magnet motor body 3 through the control cabinet 4, and an output shaft of the permanent magnet motor body 3 drives the screw pump rotary rod 8 to rotate through the drive plate 6.
Description
Technical field
The present invention is a kind of oil pumping system, is exactly a kind of direct-drive type permanent magnet synchronous motor oil pumping system that is applied to screw pump specifically.
Background technology
In the existing oil pumping system that is applied to screw pump, be mainly by belt, to drive the indirect drive screw pump of reductor by asynchronous motor.Condition of work more complicated while starting due to load, when apolegamy asynchronous motor, have to select the motor that power is larger, when this makes Asynchronous Motor Driving load, most of the time is operated in light condition, waste electric energy, its power factor and efficiency are very low, add the existence of reductor, make system effectiveness lower, and need to safeguard whole reducing gear intermittent oiling, whole driving mechanism volume is larger simultaneously, installation and maintenance are very inconvenient.The in the situation that of the unexpected power-off of oil pumping system, can not well process screw pump reverse rotation phenomenon.
Summary of the invention
The object of this invention is to provide that a kind of efficiency is high, volume is little, simple in structure, energy-conservation, the direct-drive type permanent magnet synchronous motor oil pumping system that can prevent screw pump reverse rotation.
The object of the present invention is achieved like this:
It mainly comprises screw pump interface 1, blowout preventer 2, magneto 3, switch board 4, seal 5, driver plate 6, protective cover 7, screw pump bull stick 8 form.
Its operating principle is such:
By blowout preventer (2) with magneto be (3) connected fastening after, be (8) (1) installed together with screw pump interface and be connected fastening through screw pump bull stick.
(5) sealing is arranged on to (3) axle head of magneto, with driver plate (6) by sealing (5) with magneto (3) axle head compress and be (8) connected fastening with screw pump bull stick.
By switch board be (4) arranged on magneto (3) near.
Its operation acts process is such:
After switching on power, by switch board, (4) convey electrical current to magneto (3), (6) magneto output shaft (3) drives screw pump bull stick (8) to rotate by driver plate.
The invention has the beneficial effects as follows:
Efficiency is high, volume is little, simple in structure, energy-conservation, rotating speed is adjustable, and startup and running moment of torsion are constant, can effectively prevent screw pump reverse rotation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Screw pump interface 1, blowout preventer 2, magneto 3, switch board 4 in Fig. 1, seal 5, driver plate 6, protective cover 7, screw pump bull stick 8.
Fig. 2 is the schematic diagram of protecting sheathing of the present invention
The specific embodiment
By blowout preventer (2) with magneto be (3) connected fastening after, be (8) (1) installed together with screw pump interface and be connected fastening through screw pump bull stick.(5) sealing is arranged on to (3) axle head of magneto, with driver plate (6) by sealing (5) with magneto (3) axle head compress and be (8) connected fastening with screw pump bull stick.By switch board be (4) arranged on magneto (3) near.
After switching on power, by switch board, (4) convey electrical current to magneto (3), (6) magneto output shaft (3) drives screw pump bull stick (8) to rotate by driver plate.
Claims (1)
1. a direct-drive type permanent magnet synchronous motor oil pumping system, it by screw pump interface (1), blowout preventer (2), magneto (3), switch board (4), sealing (5), driver plate (6), protective cover (7), (8) screw pump bull stick forms, it is characterized in that: by blowout preventer be connected with magneto fastening after, through screw pump bull stick, be installed together with screw pump interface and be connected fastening, sealing is arranged on to magneto axle head, with driver plate, will seal with magneto axle head and compress and be connected fastening with screw pump bull stick, switch board is arranged near magneto, after switching on power, by switch board, convey electrical current to magneto, the output shaft of magneto drives screw pump bull stick to rotate by driver plate.
