Description
Technical field:
The utility model relates to a kind of pair of horse head forward type phased crank long-stroke energy-saving oil extractor, belongs to the oil extraction machinery and equipment design field.
Background technology:
The ground machine oil production equipment that various countries, the world today adopt all is the conventional type beam-pumping unit more than 80 percent.Though the conventional type beam-pumping unit is simple in structure, reliable, durable, stroke is low, the jig frequency height, and counterbalance effect is bad, and pump efficiency is low, the energy consumption height.Along with the exploitation of the continuous decline of OW liquid level and deep layer oil well, high viscosity oil well, make that the pump degree of depth and lifting force are increasing down, therefore, cut down the consumption of energy for improving pump efficiency, press for the oil pumper of long stroke low jig frequency.Though blue elephant is realized long stroke easily, poor reliability can not satisfy the requirement of long-term failure-free operation, therefore conventional beam-pumping unit is improved, and is to realize increase stroke, the preferred approach that cuts down the consumption of energy.
Summary of the invention:
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of pair of horse head forward type phased crank long-stroke energy-saving oil extractor, makes it to have the increase stroke, the characteristics that cut down the consumption of energy.
The utility model is to realize above-mentioned purpose by following technical solution.
In the structure of a kind of pair of horse head forward type phased crank long-stroke energy-saving oil extractor, be provided with base, brake gear, motor, balance weight, phased crank, connecting rod, polished rod eye, horse head, pulley spindle, fixed pulley, wire rope, walking beam, center bearing, balance horse head, counterweight, support, staircase, crank pin, reduction box, one end of phased crank is installed on the balance weight by crank pin, and the other end of phased crank is connected with an end of connecting rod; The other end of connecting rod is installed in the front end of walking beam; Walking beam is rack-mount by center bearing; Horse head is installed in the front end of walking beam, and the balance horse head is installed in the rear end of walking beam, and counterweight is suspended on the balance horse head; Fixed pulley is installed on the horse head by pulley spindle; One end of wire rope is fastened on the crank pin, and the other end is walked around the fixed pulley that is installed on the horse head and is connected with polished rod eye.
The utility model have compared with prior art simple in structure, stressed evenly, good balance effect, increase stroke, the advantage that cuts down the consumption of energy.
Description of drawings:
Fig. 1 is the general structure schematic diagram of a kind of pair of horse head forward type phased crank long-stroke energy-saving oil extractor.
In the drawings: 1. base, 2. brake gear, 3. motor, 4. balance weight, 5. phased crank, 6. connecting rod, 7. polished rod eye, 8. horse head, 9. pulley spindle, 10. fixed pulley, 11. wire rope, 12. walking beams, 13. center bearings, 14. balance horse heads, 15. counterweights, 16. supports, 17. staircases, 18. crank pins, 19. reduction boxes.
The specific embodiment:
A kind of pair of horse head forward type of the utility model phased crank long-stroke energy-saving oil extractor is made up of base 1, brake gear 2, motor 3, balance weight 4, phased crank 5, connecting rod 6, polished rod eye 7, horse head 8, pulley spindle 9, fixed pulley 10, wire rope 11, walking beam 12, center bearing 13, balance horse head 14, counterweight 15, support 16, staircase 17, crank pin 18, reduction box 19; Crank adopts phased crank, and an end of phased crank 5 is installed on the balance weight 4 by crank pin 18, the other end of phased crank 5 be connected with an end of connecting rod 6; The other end of connecting rod 6 is installed in the front end of walking beam 12; Walking beam 12 is installed on the support 16 by center bearing 13; Horse head 8 is fixedly mounted on the front end of walking beam 12, and balance horse head 14 is fixedly mounted on the rear end of walking beam 12, and counterweight 15 is suspended on the balance horse head 14; Fixed pulley 10 is installed on the horse head 8 by pulley spindle 9; One end of wire rope 11 is fastened on the crank pin 18, and the other end is walked around the fixed pulley 10 that is installed on the horse head 8 and is connected with polished rod eye 7.
The high speed rotating of motor 3 drives phased crank 5 and slowly runs after belt transmission and reduction box 19 decelerations, pass walking beams 12 by connecting rod 6 bands again and swing up and down.
When upstroke begins, the position height of the balance weight 4 on the phased crank 5, the position of horse head 8 is low, and this moment, crank pin 18 was near with the distance of the top edge of fixed pulley 10.In the upstroke process, wire rope 11 rotates with the fixed pulley on the horse head 8 10, and the wire rope between crank pin 18 and the fixed pulley 10 is elongated.And when upstroke finished, the position of the balance weight 4 on the phased crank 5 was low, horse head 8 position height, and this moment, crank pin 18 was big with the distance of fixed pulley 10 top edges.When upstroke begins and upstroke when finishing crank pin 18 and the range difference of fixed pulley 10 top edges be the stroke of increase.In the upstroke process, the 14 following counterweights 15 of balance horse head descend.
When down stroke began, the position of the balance weight 4 on the phased crank 5 was low, the position height of horse head 8, the distance of the top edge of crank pin 18 and fixed pulley 10 at this moment.In the down stroke process, wire rope 11 rotates with the fixed pulley on the horse head 8 10, and the wire rope between crank pin 18 and the fixed pulley 10 is shortened.And when down stroke finishes, the position height of the balance weight 4 on the phased crank 5, horse head 8 positions are low, and this moment, crank pin 18 was little with the distance of fixed pulley 10 top edges.In the down stroke process, the 14 following counterweights 15 of balance horse head are risen.
