Description
The present invention relates to a kind of pumping unit that is used to aspirate down-hole crude oil, belong to technical field of petroleum extraction.
The existing pumping unit that is used to aspirate down-hole crude oil, energy consumption is big, and efficient is low, and stroke machine jig frequency is all placed restrictions on.
The objective of the invention is to design a kind of pumping unit that is used to aspirate down-hole crude oil, energy consumption is little, the efficient height, and the stroke of the pumping unit that has than oneself can increase, and jig frequency can increase.
Realize that above-mentioned purpose has designed a kind of pumping unit that is used to aspirate down-hole crude oil, comprise frame 17, motor 22, belt gear 21, reduction gears mechanism, it is characterized in that promoting gentle rope 2 and stride across the large pulley 1 that is positioned at frame 17 tops, promote the sagging connection vibration damper 3 of an end of gentle rope 2, the other end of vibration damper 3 is connected with the sucker rod of oil well, and the other end that promotes gentle rope 2 is connected with the top sheave 4 of commutator 24; The gentle rope 11 of balance strides across the pulley 20 of the chain-wheel box 19 of the equalizer pulley 14 that is arranged in frame 17 tops and frame 17 belows, one end of the gentle rope 11 of balance connects balancer weight vibration damper 15, the other end of balancer weight vibration damper 15 is connected with balancer weight 16, and the other end of the gentle rope 11 of balance is connected with the lower pulley block 8 of commutator 24; Commutator 24 comprises the housing 5 that has bearing 6, is bearing in the reversing shaft 7 in the bearing 6, and reversing shaft 7 two ends are provided with specific links 9 and chain 25 engagements, and roller 10 is housed on the specific links 9; Drive sprocket 18 is opposed to be installed on the output shaft 26 of chain-wheel box 19 middle gear reducing gears of frame 17 belows; Be positioned at output shaft 26 and back shaft 28 and on the frame 17 in drive sprocket 18 and driven sprocket 12 outsides guide track 23 be set respectively longitudinally, its length is distance between output shaft 26 and back shaft 28 axis, on the plane of chain 25, guide track 23 is positioned at the inboard of balancer weight 16 chain 25 straightways on one side.
Advantage of the present invention is a non-crank connecting rod mechanism, and stroke simple in structure can be greater than 8 meters, and jig frequency can not reduce because of stroke increases significantly.The pumping unit of the suction down-hole crude oil of same stroke and jig frequency, motor power (output) can reduce, the efficient height.
The present invention is described in further detail by embodiment below in conjunction with accompanying drawing.
Fig. 1 is that the pumping unit of suction down-hole crude oil is faced partial cutaway schematic when sucker rod descends;
Fig. 2 is that partial cutaway schematic is looked on the left side of pumping unit when sucker rod rises of suction down-hole crude oil.
The pumping unit that Fig. 1 illustrates suction down-hole crude oil is faced partial cutaway schematic when sucker rod descends.Promote the large pulley 1 that gentle rope 2 strides across frame 17 tops, promote the sagging connection vibration damper 3 of an end of gentle rope 2, vibration damper 3 can be used spring cushion, and the other end of vibration damper 3 is connected with the sucker rod of oil well, and the other end that promotes gentle rope 2 is connected with the top sheave 4 of commutator 24; The gentle rope 11 of balance strides across the pulley 20 of the chain-wheel box 19 of the equalizer pulley 14 that is arranged in frame 17 tops and frame 17 belows, one end of the gentle rope 11 of balance connects balancer weight vibration damper 15, the other end of balancer weight vibration damper 15 is connected with balancer weight 16, and the other end of the gentle rope 11 of balance is connected with the lower pulley block 8 of commutator 24; Promoting gentle rope 2 and tail rope 11 can be with wire rope or flexible broadband.Commutator 24 comprises the housing 5 that has bearing 6, be bearing in the reversing shaft 7 in the bearing 6, reversing shaft 7 two ends are provided with specific links 9 and chain 25 engagements, roller 10 is housed on the specific links 9, roller 10 every ends can be provided with two, for when sucker rod rises, commutator 24 is positioned at chain 25 the right straightways shown in Figure 1, prevent that chain 25 is subjected to unnecessary applied force, therefore on the frame 17 in drive sprocket 18 and driven sprocket 12 outsides guide track 23 is set respectively longitudinally at output shaft 26 and back shaft 28, its length is distance between output shaft 26 and back shaft 28 axis, on the plane of chain 25, guide track 23 is positioned at the inboard of balancer weight 16 chain 25 straightways on one side.When guide track 23 contacts with the roller 10 of commutator 24, guide track 23 bears vertical pressure, make the specific links 9 on the reversing shaft 7 only be subjected to the driving force of chain 25 at the straightway of chain 25, because sucker rod and balancer weight 16 balances, so the driving force of chain 25 does not need too big.This just can save energy consumption, raises the efficiency.
Fig. 2 is that partial cutaway schematic is looked on the left side of pumping unit when sucker rod rises of suction down-hole crude oil.Motor 22, logical belt gear 21 is connected with the input shaft 27 of chain-wheel box 19, and input shaft 27 drives two opposed output shafts 26 through the reduction gears mechanism double reduction gearing, on the drive sprocket 18 opposed output shafts 26 that are installed in the chain-wheel box.On the driven sprocket 12 opposed output shafts 26 that are installed in the chain-wheel box.On the driven sprocket 12 opposed output shafts 26 that are installed in the chain-wheel box.Driven sprocket 12 is opposed to be installed on the back shaft 28 of upper rack driven chain wheel seat 13 engagement in drive sprocket and driven sprocket and the chain.Chain-wheel box 19 is screwed with frame 17 and is connected.
