Abstract
The utility model provides a submersible direct-drive screw rod pump, comprising a ground part, a middle part and an underground part, wherein the ground part comprises a control cabinet and a junction box; the middle part comprises a cable; the control cabinet is electrically connected with the junction box through a cable; the underground part comprises a special submersible motor, a protector, a connector and a screw rod pump; the submersible direct-drive screw rod pump is characterized in that the special submersible motor is placed at the bottom end of the underground part and is sequentially and coaxially connected with the protector, the connector and the screw rod pump from bottom to top; and the special submersible motor is electrically connected with the junction box through a cable. The submersible direct-drive screw rod pump has the advantages of simple structure, safe and reliable work, convenience for installation and maintenance, low-rotary-speed operation and large-torque output, flexibility in control, low oil extraction power consumption and the like.
Description
Technical field
The utility model relates to a kind of screw pump, particularly a kind of latent oily directly-driven screw pump.
Background technique
At present, the used system of petroleum production is normally a kind of to place above the ground screw pump system with motor, because the design reasons of this structure, cause power plant to carry out transfer of torque to the screw pump below the km by sucker rod, this indirectly transfer mode has caused starting torque excessive, caused a large amount of idle works, reduce entire system efficient, and this indirect moment of torsion transmission by sucker rod, easily cause sucker rod to produce metal fatigue, cause the phenomenons such as disconnected bar, dropout, increase maintenance cost; For overcoming the deficiency of said system, also occurred in the prior art a kind of motor being placed below ground, this structure needs motor to drive the screw pump rotation by retarder, but because of the too small reason of environment, the retarder volume can not be excessive, this has born excessive torque load with regard to the retarder that has caused per unit volume, so that retarder is shorter working life, and the parking of often breaking down.
The model utility content
This uses novel technical problem to be solved to provide a kind of latent oily directly-driven screw pump, can not only effectively solve sucker rod wearing and tearing and the large problem of energy consumption that ground driving screw pump recovers the oil and brings, and can give full play to the superiority that down-hole drive screw pump recovers the oil, avoid decelerator trouble.
For solving the problems of the technologies described above; the utility model provides a kind of latent oily directly-driven screw pump; comprise above ground portion, intermediate portion and down-hole part; described above ground portion comprises control cabinet and terminal box; intermediate portion comprises cable; described control cabinet is electrically connected by cable with terminal box; the down-hole part comprises dive oily motor special, protector, connector and screw pump; the oily motor special of diving places the bottom of down-hole part; and successively with protector, connector and screw pump coaxial connection from bottom to top, described latent oily motor special is electrically connected with terminal box by cable.
Described latent oily motor special is permagnetic synchronous motor
Described protector adopts the column type structure.
Good effect of the present utility model is: product structure is simple, and is safe and reliable, convenient for installation and maintenance, has the output of slow-speed of revolution operation high pulling torque, and control is flexible, the oil recovery low power consumption and other advantages.
Description of drawings
Fig. 1 is the structural representation of a kind of latent oily directly-driven screw pump of the utility model preferred embodiment
Among the figure: 1. control cabinet, 2. terminal box, 3. screw pump, 4. connector, 5. protector, 6. dive oily motor special, 7. cable.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is elaborated.
With reference to Fig. 1; a kind of latent oily directly-driven screw pump of the utility model preferred embodiment; comprise above ground portion; intermediate portion and down-hole part; described above ground portion comprises control cabinet 1 and terminal box 2; intermediate portion comprises cable 7; described control cabinet 1 is electrically connected by cable 7 with terminal box 2; the down-hole part comprises the oily motor special 6 of diving; protector 5; connector 4; with screw pump 3; the oily motor special 6 of diving places the bottom of down-hole part; and successively with protector 5; the coaxial connection from bottom to top of connector 4 and screw pump 3, described latent oily motor special 6 is electrically connected with terminal box 2 by cable 7.
Described latent oily motor special 6 is permagnetic synchronous motor
Described protector 5 adopts the column type structure.
During work, by the latent oily motor special 6 of ground control cabinet 1 control, it is carried out stepless time adjustment control, it is moved with the slow-speed of revolution, high pulling torque output is recovered the oil by direct drive screw pump 3.The tactic pattern that this direct driving is recovered the oil has been saved sucker rod, mechanical deceleration device, and is simple in structure, improved system effectiveness, reduced rate of fault and energy consumption, saved cost.This structure does not have valve body and runner, and water conservancy loss is few, and medium sucks and arrange the mountain continuously, is difficult for the sand card, is difficult for producing gas lock yet, therefore transmits kind wider range of liquid, comprises high viscosity, the high content of wax, contains the crude oil of sand, gassiness.
Above-described only is preferred embodiment of the present utility model; institute is understood that; above embodiment's explanation just is used for helping to understand method of the present utility model and core concept thereof; and be not used in and limit protection domain of the present utility model; all any modifications of within thought of the present utility model and principle, making, be equal to replacement etc., all should be included within the protection domain of the present utility model.
Claims (3)
