The present invention is superior to available walking beam pumping unit, and has the features of high effective load factor, low power consumption, small size, less dead weight and low cost.
Description
Technical field:
The present invention relates to lifting device used in the oil field machinery oil field, especially composite cylinder type pulsing decelerating energy-saving oil pumping machine.
Background technology:
Under condition of market economy, oil field development must be the center with the economic benefit, greatly develops energy-saving beam pumping unit, reduces energy consumption, reduces cost for oil production.In cost for oil production, the oil pumper electricity charge account for about 30%, and pumping unit system efficient and power saving rate improve 1 percentage point, will bring considerable economic, and therefore, developing energy-efficient oil pumper has very significance.Along with Oilfield developing, technology constantly develops, mechanical oil recovery equip ment from the beam pumping unit to the submersible electric pump, screw pump etc., of a great variety, to adapt to the needs of different productive lives.The existing oil pumper that is used for artificial lift is based on beam pumping unit, and beam pumping unit is to utilize quadric chain to realize the purpose of well liquid lifting.The oil pumper pay(useful) load rate of this structural shape is low, and power consumption is high, and machine packet size and deadweight are all very big, and one-time investment is more, is unfavorable for applying.
Summary of the invention:
Low in order to solve existing beam pumping unit pay(useful) load rate, power consumption is high, machine packet size and from great, the problem that one-time investment is more, the invention provides a kind of composite cylinder type pulsing decelerating energy-saving oil pumping machine, this composite cylinder type pulsing decelerating energy-saving oil pumping machine has pay(useful) load rate height, and it is low to consume energy, machine packet size and deadweight are all little, the characteristics that one-time investment is few.
Technical scheme of the present invention is: this composite cylinder type pulsing decelerating energy-saving oil pumping machine comprises bearing and pulsing decelerating device, be fixed with the pulsing decelerating device that is connected with motor on the bearing, be connected with seating nipple and counterweight tube on the pulsing decelerating device output shaft, be fixed with support arm on the bearing of seating nipple correspondence, supporting arm front end is connected with pulley, the flexible drive parts that twines on the seating nipple is connected with the down-hole oil production pump by pulley, and the counterweight wire rope that twines on the counterweight tube is connected with the ballast box under the bearing.
Be connected with telescopic arm in the support arm in the such scheme, the telescopic arm upper end is connected with pulley; Ballast box places in the slideway under the bearing.
The present invention has following beneficial effect: this composite cylinder type pulsing decelerating energy-saving oil pumping machine is owing to take such scheme, cancelled quadric chain by using the pulsing decelerating device, type of belt drive and balance mode have been changed, and by the realization of the ballast box on counterweight tube accumulation of energy effect, thereby improved the pay(useful) load rate, because the special construction of pulsing decelerating device, in the time of can realizing the oil pumper down stroke, motor does not participate in the balance acting, has effectively reduced power consumption so more.Owing to adopted the combined type cylinder, make the stroke of ballast box, can not be subjected to the restriction of driving stroke and design, the advantage of this structure is effectively to reduce whole height.
Because above-mentioned special construction makes obviously to reduce complete machine packet size and deadweight than conventional pumping unit, so it is more to have reduced one-time investment, helps more applying.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is vertical views of Fig. 1.
1-bearing among the figure, 2-pulsing decelerating device, 3-motor, 4-seating nipple, 5-counterweight tube, 6-support arm, 7-pulley, 8-flexible drive parts, 9-counterweight wire rope, 10-ballast box, 11-telescopic arm.
The specific embodiment:
The invention will be further described below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with shown in Figure 2, this composite cylinder type pulsing decelerating energy-saving oil pumping machine comprises bearing 1 and pulsing decelerating device 2, be fixed with the pulsing decelerating device 2 that is connected with motor 3 on the bearing 1, be connected with seating nipple 4 and counterweight tube 5 on pulsing decelerating device 2 output shafts, be fixed with support arm 6 on the bearing 1 of seating nipple 4 correspondences, be connected with telescopic arm 11 in the support arm 6, telescopic arm 11 upper ends are connected with pulley 7, the flexible drive parts 8 that twines on the seating nipple 4 is connected with the down-hole oil production pump by pulley 7, and the interior ballast box 10 of the counterweight wire rope 9 that twines on the counterweight tube 5 and the slideway under placing bearing 1 is connected.
During actual the use, at first bearing 1 is fixed on the basis of well head one side, again with motor, pulsing decelerating device 2, seating nipple 4, counterweight tube 5 and in be connected with telescopic arm 11 support arm 6 be connected on the bearing 1, make flexible drive parts 8 and well head centering by adjusting telescopic arm 11, at last the flexible drive parts 8 that twines on the seating nipple 4 is connected with the down-hole oil production pump by pulley 7, the interior ballast box 10 of the counterweight wire rope 9 that twines on the counterweight tube 5 and the slideway under placing bearing 1 is connected, and can normally use.Motor 3 drives 2 motions of pulsing decelerating device, because of pulsing decelerating device 2 utilizes special changement, under direction of power shaft of pulsing decelerating device 2 is rotated, can obtain the regular rotation of the positive and negative both direction of exchange repeatedly at output shaft at pulsing decelerating device 2, also just drive seating nipple 4 and the 5 forward and reverse rotations of counterweight tube, flexible drive parts 8 on the seating nipple 4 drives the down-hole oil production pump and pumps, but also can come accumulation of energy, the power of balance up-down stroke by 9 times connection ballast boxes 10 of counterweight tube 5 counterweight wire rope.Because of pulsing decelerating device 2 has function of stepless speed regulation, make the jig frequency of oil pumper can be from regulating arbitrarily between 0-10, and motor do work can realize the oil pumper down stroke time.Can realize regulating arbitrarily stroke by displacement and time relay adjustment.Make this oil pumper have better energy-saving effect.Thereby cancelled quadric chain by pulsing decelerating device 2, changed motion mode, improved the pay(useful) load rate, reduced power consumption, reduced machine packet size and deadweight, it is more to have reduced one-time investment, more is added with to help applying.
