Description
Technical field:
The present invention relates to the improvement of motor pulley structure.
Background technique:
Along with the oil field enters high water-cut development period, the application area of pumping unit mechanical oil production model is day by day extensive, and the application time prolongs gradually, and oil well is taken out the initial stage in commentaries on classics, and the design of its machine, bar, pump mainly concentrates on the nineties initial stage of twentieth century.At present, because the oil field has entered the high water-cut development later stage, along with the continuity of exploitation, crude oil in the recverable oil layer reduces day by day, will guarantee stable production of crude oil in development late stage, mainly relies on the mode of extract, simultaneously because the production fluid requirement of different times needs the pumping well parameter dynamically to adjust.The pumping unit parameter adjustment comprises that type adjustment, motor adjustment, stroke adjustment, jig frequency adjustment and pump directly adjust.The most simple and practical method is the adjustment to jig frequency.And mainly be the diameter of adjusting motor pulley to the adjustment of jig frequency, the variation by the belt pulley size reaches the production fluid amount that improves or reduce oil well, and pumping well is produced under a rational working state.Because the active time of pumping well is longer, following problem often appears when adjusting belt pulley: the one, and the phenomenon of belt pulley corrosion is very outstanding, field stripping is wasted time and energy, generally changing a belt pulley needs about 30 minutes time, sometimes belt pulley corrosion is serious, pull-up device also can dismount badly belt pulley during dismounting, and belt pulley is scrapped; The 2nd, because type that different exploitation is equipped with period and motor is different, size one machine of required belt pulley is the same, can only rely on processing again, could change then, causes the off-time long; The 3rd, because motor model difference, d-axis and inclined shaft size differ, and cause belt pulley to exchange poor performance.Some oil well has been installed adjustable frequency motor in order to realize dynamic adjustment, though adjustable frequency motor is easy to adjust, price is too expensive, and 200,000 yuans of general every needs have increased cost for oil production greatly.The patent No. is ZL95232916.6, name is called " a kind of formula belt of oil pumping machine wheel easy to assemble ", application number is 91227362.3, name is called " suit belt pulley on the pumping well motor ", the patent No. is ZL99224660.1, name is called " the box-like belt of oil pumping machine wheel of nested groups ", the patent No. is ZL99222441.1, name is called the patent of invention of " combined type parameter easy adjusting belt of oil pumping machine wheel ", disclosed all is that the cover of big small belt pulley adds, the cover of this big small belt pulley adds, can only rely on the connection of bolt between it is mutual, its mechanical strength is high like that not as a belt pulley body, and processing cost exceeds more than one times than a belt pulley body.Mechanical strength is low, processing charges is high, be not suitable for the pumping well running of 24 hours every days because these belt pulleys exist, so do not form commodity so far.
Summary of the invention:
The purpose of this invention is to provide a kind of need and can finish in two minutes and change the speed pulley of oil field with motor, it have simple in structure, cost is low, easy replacing, replacing speed is fast, interchangeability good, advantage of wide range of application.The present invention is made up of baffle plate 1, set screw 2, belt foreign steamer 3, spline housing 4; The central shaft of spline housing 4 is to having motor shaft hole 7, have keyway 6 in the motor shaft hole 7, be axially arranged with spline 5 on the curved surface of spline housing 4, spline housing 4 axial ends are provided with retaining platform 10, the spline housing 4 axial the other ends have screw 8, the central shaft of belt foreign steamer 3 is to having through hole 12, in the through hole 12 of belt foreign steamer 3 with spline housing 4 on spline 5 have spline 11 accordingly, spline housing 4 matches with the through hole 12 of belt foreign steamer 3, have screw hole 9 on the baffle plate 1, screw 8 on set screw 2 and the spline housing 4 screws, baffle plate 1 is fixed on the side that has screw 8 of spline housing 4, and the spline 5 on the described spline housing 4 is Spielpassung with the spline 11 of belt foreign steamer 3.Advantage of the present invention is: one, unified the size of motor output shaft by the effect of spline housing 4, realized the dynamic adjustment of pumping well parameter by the variation of belt foreign steamer 3 outside dimensions; Two, dismounting only needs belt foreign steamer 3 is taken down during belt pulley, and is convenient, laborsaving, save time, and the take-down time shortens 90% than in the past, improved working efficiency, has shortened and has stopped the well time; Three, interchangeability is good, and many mouthfuls of wells are realized the exchange use of belt foreign steamer, and that can reduce belt pulley overstocks the expense nearly 1/3rd that can save belt pulley; Four, the spline 11 because of the spline on the spline housing 45 and belt foreign steamer 3 is Spielpassung, mounts and dismounts laborsavingly, has avoided belt pulley to scrap the generation of accident; Five, compared with the prior art, yield increase effect is remarkable, motor pulley average out to of past dismounting 20 minutes only needed 2 minutes can finish replacing now, and on average saving time is 18 minutes, motor pulley according to every mouthful of well is every year on average changed once, then individual well on average produces 0.075 ton of crude oil less, by 1000 yuan of calculating of oil price per ton, and the annual economic benefit that increases by 75 yuan of individual well, according to another caculation, using the input-output ratio of every mouthful of well of the present invention is 1: 1.5625; Because reduced the overstocking of belt pulley, interchangeability is good, the minimizing of processing charges, dismounting speed is fast, average every mouthful of well can be saved nearly 700 yuans every year.
