Abstract
A kind of long-stroke pumping unit without walking beam belongs to oil exploration equipment.The present invention adopts the chain type travel prolongation mechanism to increase the stroke of pumping unit; The suspension point commutation realizes by connecting rod tractive changement; Outstanding rope chain moves back and forth transmission power in the top of head sheave and third wheel outer rim.This machine functional reliability and durability are strong, operate steadily.12 tons of suspending point loadings, length of stroke is 6 meters, is applicable to the petroleum production of general oil well, more suitable height is sticking, rich gas, many sand, heavy wax, water logging and deep mining.
Description
The present invention is a kind of long-stroke pumping unit without walking beam, belongs to the petroleum production manufacturing mechanism.
At present, the domestic no slide beam long stroke pumping unit that uses in oilfield exploitation has the above pumping unit of steel cable distance-increasing type long stroke pumping unit of CN86102979 path chain formula pumping unit and CN85103185 to exist various deficiencies respectively.Many as path chain formula pumping unit easily damaged parts, functional reliability and poor durability, commutation specific links, cylinder balancing sealing etc. are easily damaged parts, and path chain produces than high acceleration at last lower dead centre, and the suspension point commutation owes steady.Steel cable distance-increasing type long stroke pumping unit, fatigue ruption takes place in the increment steel cable because of bending radius is little, working life is short, eccentric wear and curved card take place in the balancer weight guide rail under the tractive moment loading of the public fast line of increment slide rail set, boundary dimension height, weight are big, especially a day wheel diameter reaches 4.5 meters, shows top-heavy, and global stability is poor.Above-mentioned pumping unit is subjected to the influence of casing or height all to exist maintenance and repair inconvenience, regulates the problem of stroke and jig frequency trouble.
The objective of the invention is to overcome the deficiency of above-mentioned long-stroke pumping unit without walking beam, for petroleum production provides a kind of simple in structure, functional reliability, durability height, advanced technology, repaiies the novel long-stroke pumping unit without walking beam of easily making well.
Main structure of the present invention has: support, frame; Motor, v belt, Vee pulley V, speed reducer; The slide block draw-off mechanism comprises: connecting rod, slide block, slide rail, reversing chain, the sprocket wheel that commutates up and down; Travel prolongation mechanism comprises: increase the journey sprocket wheel, increase the journey chain, the sprocket-type head sheave; Outstanding rope chain type balance sysmte comprises: outstanding rope chain, balancer weight, guiding third wheel suspension point etc.
Fig. 1 is the structural representation of long-stroke pumping unit without walking beam.
Elaborate below in conjunction with accompanying drawing: support 24 links to each other with frame 23, and other structure of pumping unit is installed in respectively on support 24 and the frame 23.Motor 1 links to each other with speed reducer 3 by Vee pulley V 25; Crank 4 is housed on the reduction gearbox output shaft; One end of crank 4 links to each other with connecting rod 5 and constitutes connecting rod; Slide block 7 in the slide rail 22 links to each other with an end of reversing chain 8 and connecting rod 5; Reversing chain 8 is bearing on the commutation sprocket wheel 6,9; By connecting rod rotatablely moving of motor 1 is converted to slide block 7 and the vertical linear reciprocating motion of reversing chain 8 in slide rail 22.Commutation sprocket wheel 9 with increase journey sprocket wheel 10 with being loaded on the sprocket shaft 20; Increase journey sprocket wheel 14 and be loaded on sprocket shaft 21 together with sprocket-type head sheave 15; Increase journey sprocket wheel 10 and increase journey sprocket wheel 14 and link to each other by increasing journey chain 12.By commutation sprocket wheel 9 with increase journey sprocket wheel 10, the pitch diameter that increases journey sprocket wheel 14 and sprocket-type head sheave 15 is formed the chain travel prolongation mechanism by bigger than 2～4 multiplications surely, it makes the stroke of slide block obtain amplifying.The sprocket wheel of travel prolongation mechanism counterclockwise back and forth rotates along suitable around sprocket shaft when work.Outstanding rope chain 13 is by sprocket-type head sheave 15, guiding third wheel 16 and directly lodges are on the gear teeth of sprocket-type head sheave 15 upper limbs and guiding third wheel 16 upper limbs, and an end of outstanding rope chain is consolidated in suspension point 11 and connects the extension polished rod, and the other end directly hangs the formula balancer weight 17 that sinks.
Complete machine external dimension of the present invention are little, and total height is 9 meters, and gross weight is 18 tons.This machine travel prolongation mechanism adopts chain-driven; Thereby the suspension point commutation realizes the suspension point commutation by connecting rod traction sliding block 7 tractive changements, and the commutation acceleration is little, and it is reliable to operate steadily; Adopt outstanding rope chain balance sysmte, the direct hanging balancing in outstanding rope chain 13 two ends weighs 17 and polished rod, wherein balancer weight 17 does not support the formula that sinks for having, and sinks in the groove that sinks work safety, complete machine is low to the field work environmental requirement, this pumping unit does not have easily damaged parts, and no guard shield is regulated stroke, jig frequency is all carried out on ground, and operation and maintenance is convenient.This machine moving-mass is little, thereby inertia loading is little, and energy loss is low.Strokes per minute is low, is 2.5 times/minute～6.5 times/minute; Suspending point loading is big, is 12 tons; Point suspension movement is 15 meters/minute～39 meters/minute, can make the suction of pump be full of the raising pump efficiency, because stroke is long, is 6 meters; Loss of plunger stroke is little relatively, and the pumping liquid measure is big.It is not only applicable to the petroleum production of general oil well, more is applicable to high sticking, rich gas, many sand, heavy wax, water logging and deep-well petroleum production or powerful exploitation.Its usability is wide, under identical polished rod load, can realize dark pump extension or small pump diameter, and little load under identical pump setting depth, can be realized the performance characteristic of big pump diameter, long stroke, big discharge capacity.
Embodiment: the present invention drops into and recovers the oil when producing, and complete machine is placed on the basis, sets up stroke, jig frequency; Make slide block 7 and reversing chain 8 in the connecting rod tractive slide rail 22 carry out up-and-down movement, amplify by the stroke of travel prolongation mechanism slide block 7, and make sprocket-type head sheave 15 along back and forth rotating along counter clockwise direction, thereby make outstanding rope chain 13 on sprocket-type head sheave 15 and guiding third wheel 16, move back and forth transmission power, polished rod fixed on the balancer weight 17 at outstanding simultaneously rope chain 13 two ends and the suspension point 11 is finally realized long stroke pumping fluid in the up-and-down movement of frame both sides by outstanding to-and-fro motion of restricting chain 13.Can realize by the radius of change crank 4, rotating speed or the replacing triangle belt leather wheel 25 that the adjusting jig frequency can change motor 1 when regulating stroke.
