Two, technical background:
The invention of beam pumping unit, development and the history in existing over one hundred year of use, it is durable for a long time with its heavily fortified point, reliably, easy to use, advantages such as maintenance cost is low occupy the leading position of oil field sucker rod pumping always, but because its complex structure, technology is ancient, in decades, domestic and international many oil pumper producers and development personnel, the renewal product of successively developing along the pattern of beam pumping unit miscellaneous does not all break away from its essential characteristic---and will rotatablely move by linkage becomes rectilinear motion, therefore, this oil pumper all exists structure huge, system effectiveness is low, high problem consumes energy, bigger with the fundamental state policy gap of national energy-saving and emission-reduction, meanwhile, China oil pumper development personnel also get rid of horse head one after another in order to overcome these problems, the walking beam connecting rod, successively develop chain drive pumping unit, belt oil pumping machine, hydraulic pumping unit, a large amount of new special type oil pumpers such as linear motor oil pumping machine and oil sucking machine of compound permanent magnet motor, these technology all are to adopt to come and go the oil pumper that the pylon form is carried out the oil recovery of bar pump, but, these oil pumper great majority and immature, major technique does not also have perfect, thereby bring structure comparatively complicated, fault is many, the on-site maintenance difficulty, the new problem that manufacturing cost and use cost is all higher is unfavorable for promoting.
Three, the content of utility model
The purpose of this utility model:, provide a kind of simple in structure, cost is low, efficient is high, energy consumption is low, easy to use energy-efficient tower-type pumping unit that has no squirrel-cage permanent-magnet synchronous motor in order to overcome the defective of prior art.
The technical solution of the utility model: a kind of energy-efficient tower-type pumping unit, mainly form by no squirrel-cage permanent-magnet synchronous motor (1), combination adhesive tape (2), reducer (3), rope sheave reel (4), boom hoist cable (5,12), balancing weight (6), movable pulley (7,13), fixed pulley (8,9,10,11), polished rod eye (14), tower frame (15), variable frequency control cabinet (16).It is characterized in that: no squirrel-cage permanent-magnet synchronous motor (1) is installed in the bottom of tower frame (15), reducer (3) is installed in two layers of tower frame (15), fixed pulley (8,9,10,11) be installed in the top of tower frame (15), rope sheave reel (4) on the reducer (3) uses boom hoist cable (5) through fixed pulley (9,8) link to each other with movable pulley (7), movable pulley (7) links to each other with balancing weight (6), rope sheave reel (4) on the reducer (3) uses boom hoist cable (12) through fixed pulley (11,10) link to each other with movable pulley (13), movable pulley (13) links to each other with polished rod eye (14), polished rod eye (14) and oil pumping polish rod are fixedly connected, the power shaft of the belt pulley of no squirrel-cage permanent-magnet synchronous motor (1) and reducer (3) links to each other with combination adhesive tape (2), and no squirrel-cage permanent-magnet synchronous motor (1) is connected with power supply by variable frequency control cabinet (16).
Described no squirrel-cage permanent-magnet synchronous motor is a kind of efficient permanent magnet synchronous motor, its mechanical efficiency height, and the power factor height does not have sliver, conducting ring etc. and produces the faradic part of excitation on its rotor, controlled by special-purpose permagnetic synchronous motor variable frequency control cabinet.
Be set with brake gear on the power shaft of described reducer (3), this brake gear is connected with operating grip on being installed in tower frame (15) by backguy or pull bar.
The beneficial effects of the utility model:
1. the utility model has increased substantially the efficient of oil pumper, and has reduced energy consumption significantly.The surface efficiency of prior art beam pumping unit is lower, though the oil pumper that has has reduced transmission link, but because majority is all pursued the slow-speed of revolution, high pulling torque, selected the external rotor electric machine of high number of poles for use, yet the motor of high number of poles, common mechanical efficient, power factor all is lower than the number of poles motor, add Low speed electric motor when waiting moment of torsion frequency modulation, power attenuation is big, so its surface efficiency is also all lower, simultaneously because low stroke, down-hole efficient is also low, the general energy-saving effect of present tower-type pumping unit is all good, main cause is to have improved down-hole efficient, owing to change long pump into, carry out the long stroke operation and obtained the bigger raising of underground system efficient, so the utility model has adopted the tower-type pumping unit structure, has the high down-hole benefit of long stroke operation, simultaneously again because earth construction has adopted high efficiency no squirrel-cage permanent-magnet synchronous motor, mechanical efficiency and power factor are all than higher, though used reducer, again through the loss of transmission system, total surface efficiency still is higher than conventional pumping unit, system effectiveness is greatly improved, and energy-saving effect is fairly obvious.
2. the utility model is simple to operate; easy to use; owing to adopted high efficiency no squirrel-cage permanent-magnet synchronous motor; its rotating speed can electrodeless adjusting in the power frequency scope; startup can frequently commutate simultaneously; rotating speed through reducer output; have enough big moment of torsion and satisfy the requirement that oil pumper is transferred ginseng; regulate stroke; jig frequency is very convenient; the variable frequency control cabinet is regulated operating frequency can change jig frequency; change the travel switch position and can change stroke, simultaneously, the multiple protection functions of frequency converter has been realized Based Intelligent Control to oil pumper; hand-operated brake device and automatic control brake function have increased the safety factor of system in addition, make the well head facility fool proof.
3. the utility model is simple in structure, technical maturity, making, installation all do not have difficulty higher parts and technology in addition, cost of production is low, because overall structure is greatly simplified, complete machine weight only be same model conventional beam-pumping unit about 40%, save a large amount of steel, manufacturing cost is also less than 60% of conventional beam-pumping unit.
4. the utility model is used broad covered area, can make the different oil pumper of all size, is easy to promotion and implementation, has good social benefit and economic benefit.
