Description
Technical field the utility model relates to a kind of one for field produces and directly drives extracting device of oil without counterweight, belongs to petroleum recovering machinery class.
The existing oil recovery machiner in background technology oil field, more than 90% is beam pumping unit, and profile is huge, and weight is large, floor space is large, and adjust ginseng complicated, energy consumption is high, and power transfer path is long, and efficiency is low, and fault rate is high, can not be applied in offshore oilfield.
Summary of the invention the purpose of this utility model is that providing a kind of directly drives extracting device of oil without counterweight, this device utilizes pinion and rack that the rotary motion of motor is directly converted to rectilinear motion, utilize energy back that polished rod down stroke produces by frequency converter feedback system to electrical network, thus cancel ballast box structure, make complete machine mechanism compact, power transfer path is short, and efficiency is high.
The purpose of this utility model is achieved in that it is by polished rod (1), tooth bar lower guide and lubrication assembly (2), motor (3), reducer (4), gear (5), interior pipe (6), tooth bar assembly (7), optical-rod clamp (8), tooth bar upper rall assembly (9), switch board (10), casing (11) forms, its assembled relation is: motor (3) is directly connected to by flange on the power shaft of reducer (4), the output shaft of reducer (4) is installed gear (5), engage centered by position by gear (5) with tooth bar assembly (7), a closed casing (11) is set up to be sealed by wheel and rack, lubrication oil will be stored in casing (11), the adpting flange connecting tooth bar lower guide and lubrication assembly (2) is had in the bottom of casing (11), the adpting flange connecting tooth bar upper rall assembly (9) is had on the top of casing (11), interior pipe (6) and tooth bar lower guide and the bottom of lubricating assembly (2) are connected and rely on thread seal, simultaneously, pipe (6) is inserted in tooth bar assembly (7), the external diameter of interior pipe (6) is less than the internal diameter of tooth bar assembly (7), polished rod (1) enters from interior pipe (6), fix with optical-rod clamp (8) on the top of tooth bar assembly (7).
Operating principle of the present utility model is: utilize pinion and rack to be rectilinear motion by convert rotational motion, control motor commutation and rotating speed is utilized to come rotating and the rotating speed of control gear, the deceleration force amplifier mechanism of reducer is utilized to amplify the driving force of motor, the energy feedback that polished rod down stroke produces by employing frequency converter dragging motor, frequency converter energy feedback system is to electrical network, thus the design realized without ballast box, reach the feature that mechanism is compact, consumptive material is few.
Description of drawings 1 directly drives extracting device of oil schematic diagram for a kind of without counterweight, is described further enforcement of the present utility model below in conjunction with accompanying drawing.
Detailed description of the invention as shown in Figure 1, the utility model is by polished rod 1, tooth bar lower guide and lubrication assembly 2, motor 3, reducer 4, gear 5, interior pipe 6, tooth bar assembly 7, optical-rod clamp 8, tooth bar upper rall assembly 9, switch board 10, casing 11 forms, its assembled relation is: motor 3 is directly connected on the power shaft of reducer 4 by flange, the output shaft of reducer 4 installs gear 5, engage centered by position by gear 5 with tooth bar assembly 7, a closed casing 11 is set up to be sealed by wheel and rack, lubrication oil will be stored in casing 11, the adpting flange connecting tooth bar lower guide and lubrication assembly 2 is had in the bottom of casing 11, the adpting flange connecting tooth bar upper rall assembly 9 is had on the top of casing 11, interior pipe 6 and tooth bar lower guide and the bottom of lubricating assembly 2 are connected and rely on thread seal, simultaneously, pipe 6 is inserted in tooth bar assembly 7, the external diameter of interior pipe 6 is less than the internal diameter of tooth bar assembly 7, the top of interior pipe 6 is higher than the lubrication oil dynamic liquid level height in casing 11, polished rod 1 enters from interior pipe 6, fix with optical-rod clamp 8 on the top of tooth bar assembly 7.Frequency converter dragging system and energy feedback system is had in switch board 10.
