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.
