Abstract
The utility model discloses a direct-drive permanent-magnet synchronous motor oil pumping system. The direct-drive oil pumping system mainly comprises a screw pump connector, a blowout preventer, a permanent magnet motor, a control cabinet, a seal, a transmission plate, a protective cover, and a screw pump rotary rod. The blowout preventer is connected and fastened with the permanent magnet motor, and then penetrates through the screw pump rotary rod and is mounted together with the screw pump connector and is connected and fastened. The seal is mounted at a permanent magnet motor shaft end, and the transmission plate is used for pressing the seal and the permanent motor shaft end tightly and is connected and fastened with the screw pump rotary rod. The control cabinet is mounted near the permanent magnet motor. After power-on, electric current is transported to the permanent motor through the control cabinet, and an output shaft of the permanent magnet motor drives the screw pump rotary rod to rotate through the transmission plate.
Description
Technical field
The utility model 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.
Utility model content
The purpose of this utility model 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 purpose of this utility model is achieved in that
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 beneficial effects of the utility model are:
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 utility model
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 utility model
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.
