The specific embodiment
This passive PIG in Oil Pipeline comprises sun gear 1, planetary gear 2, central gear 3 and impeller 4.The two ends of sun gear 1 are provided with front sealing plate 6 and rear sealing plate 7 by fixed bar 5 respectively.
The outside of front sealing plate 6 and rear sealing plate 7 is fixed with respectively front leather cup 8 and the rear leather cup 9 of being made by silica gel material.On front sealing plate 6, rear sealing plate 7, front leather cup 8 and rear leather cup 9, be respectively arranged with centre bore 12.
In sun gear 1 between front sealing plate 6 and rear sealing plate 7, by front sealing plate 6 and rear sealing plate 7, be triangular shape planet pin 10 is installed.On planet pin 10, be movably installed with respectively planetary gear 2, in the sun gear 1 between planetary gear 2, central gear 3 be housed.Between sun gear 1 and central gear 3 and front sealing plate 6 and rear sealing plate 7, be separately installed with ball 11; Effectively to reduce the frictional resistance of 3 of front sealing plate 6 and rear sealing plate 7 and sun gear 1 and central gears, make it to relatively rotate.
In central gear 3, be provided with impeller 4, impeller 4 is fixedly connected with central gear 3.On the appearance circumference of sun gear 1, be provided with a plurality of grooves, in groove, by bearing pin, be movably installed with respectively hobboing cutter 13.In the shape of a spiral, one end of hobboing cutter 13 is provided with pin shaft hole 14 to hobboing cutter 13, and the other end of hobboing cutter 13 is provided with telescopic spring bar 15.
The circumferential inner surface of sun gear 1 is provided with driving cog, and planetary gear 2 is connected with a joggle with central gear 3 and sun gear 1 respectively.
When this passive PIG in Oil Pipeline is used, by delivery device, put in the oil pipeline of working, crude oil impacts impeller 4 by centre bore 12 to be made it start to rotate and drives this wiper integral body to move ahead, in this course, impeller 4 drives central gear 3 to rotate, and drive sun gears 1 to rotate by planetary gear 2, the more long-pending wax rotary-cut on tube wall is got off by the hobboing cutter 13 on it by sun gear 1, thereby complete the cleaning work of oil pipeline.The chip that cleaning work produces flows away with crude oil.
The hobboing cutter 13 of this passive PIG in Oil Pipeline is movable installation, and one end of hobboing cutter 13 can be rotated around bearing pin under telescopic spring bar 15 effects of the other end in groove.When hobboing cutter 13 runs into enough large radial load, the inside Compress Spring expansion link 15 of hobboing cutter 13, to avoid hobboing cutter 13 to damage blade and pipeline when elbow or pipeline large deformation place contact with tube wall rigidity, when hobboing cutter 13 force in radial weaken, hobboing cutter 13 sets back.
The front leather cup 8 of this passive PIG in Oil Pipeline and rear leather cup 9, when running into bend, have guiding and supporting role, so that this wiper passes through bend pipe smoothly.When in the course of work, if the place ahead runs into thicker wax layer, front leather cup 8 inwardly shrinks so that this wiper continues to move ahead under drag effect, but front line speed slows down, now the flow by runner (centre bore 12) increases, the output torque and rotational speed of impeller 4 increases, the cutting force of hobboing cutter 13 and cutting speed also increase thereupon, thereby thick wax layer is excised.When the place ahead wax layer is thinner, the suffered resistance of this wiper is less, and axially the speed of service is relatively large, and impeller 4 rotating speeds are relatively little, and the cutting force of hobboing cutter 13 is equally also relatively little.
After operation completes, by wiper retracting device, receive and reclaim this wiper, then this wiper is detected, cleans, stored, in order to using next time.
