Description
The utility model relates to the petroleum production instrument, is a kind of linear motor driving non-beam beam-pumping unit that is used for oil field surface mining oil.
Present field use pumping unit the most widely is by quadratic crank mechanism, and rotatablely moving of motor is converted into pumping of sucker rod polished rod, thereby drives downhole pump.The pumping unit floor space of this structure is big, the consumption steel are many, device is complicated, power demand is big, system effectiveness is low, and it is big to adjust the working system workload aborning.The method that Chinese patent application 94108326.8 discloses a kind of " DC linear electric motor of motor pump at the bottom of the control well ", this method is that linear electric motor and pump are installed under oil well, do the motion of pumping of a fulcrum with the well casing base, linear motor stator electric has adopted 3 pulsed coils, and linear motor rotor adopts the permanent magnet of a plurality of equidistant accumulations.The linear electric motor of this structure improve the power of motor difficulty because the well casing space is limited, and electric control element is installed in the down-hole, and maintenance or replacing element difficulty have strengthened the intensity of oil well operation.
China Patent No. 96217683.9 discloses a kind of " adopting the pumping unit of linear motor driving ", and this pumping unit is fixed on ground with linear electric motor and transmission system thereof, by sucker rod power is reached underwell pump, realizes the function of pumping according to this.The sucker rod that this pumping unit links to each other with underwell pump is to be fixed on the linear motor rotor of hollow structure with deck, and the positioning block on the linear motor rotor leans against on the limited post, keeps the electromagnetism air gap and sets upright well casing.Wire rope on derrick is by pulley two termination deck and balancing weights, balance rod weight and oil-pumping resistance.Because the linear electric motor of pumping unit are fixed on well head, the underground work difficulty, in case power failure or mistake are carried, can not realize brake or braking, increase the dangerous factor of system, because electric efficiency is on the low side, do not reach purpose of energy saving, and only be applicable to the middle-shallow layer oil well, after this electric machine structure is determined, rely on to change the parameter of electric machine to regulate oil well production working system difficulty big.
The purpose of this utility model is to overcome the deficiencies in the prior art, and the linear motor driving non-beam beam-pumping unit that a kind of floor space is little, in light weight, energy-efficient, the accent ginseng is convenient, be convenient to keep in repair is provided.
The purpose of this utility model is achieved in that
A kind of linear motor driving non-beam beam-pumping unit, mainly by rope hanger 3, wire rope 4, sheave block 5, support 6, linear motor stator electric 7, linear motor rotor 8, cable 9, balancer weight 10, leading screw 11, control cabinet 12, snubber 13, buffer 14 is formed, support 6 tops are equipped with sheave block 5, linear motor stator electric 7 is installed in the interior both sides of support 6, linear motor rotor 8 is installed in the middle of the linear motor stator electric 7, wire rope 4 connects rope hanger 3 and linear motor rotor 8 by sheave block 5, balancer weight 10 is connected the lower end of linear motor rotor 8, and linear motor rotor 8 and balancer weight 10 are installed in the same side of support 6.
The purpose of this utility model can also realize like this:
Upper and lower end at linear motor stator electric 7 is equipped with snubber 13, at the upper and lower end of support 6 buffer 14 is installed, and support 6 bottoms or top are equipped with leading screw 11, and sheave block 5 can be single group or many groups, and snubber 13 has four.Linear motor rotor 8 and linear motor stator electric 7 are plane structure, and are vertically to arrange.
The utility model accompanying drawing is a linear motor driving non-beam beam-pumping unit structural representation.
The utility model has the advantages that: linear electric motors participate in gravitational equilibrium, few, the consumed power of drive disk assembly Less, high efficiency, complete machine is in light weight, floor space is little, the motion of linear electric motors can be defeated by regulating Enter electric current and control, can conveniently abdicate the above space of well head during oil well operation, be applicable to various degree of depth oil wells The oil recovery requirement.
Further specify the utility model below in conjunction with accompanying drawing.
The linear motor driving non-beam beam-pumping unit, mainly by rope hanger 3, wire rope 4, sheave block 5, support 6, linear motor stator electric 7, linear motor rotor 8, cable 9, balancer weight 10, leading screw 11, control frame 6, linear motor stator electric 7, linear motor rotor 8, cable 9, balancer weight 10, leading screw 11, control cabinet 12, snubber 13, buffer 14 is formed, at support 6 tops sheave block 5 is installed, sheave block 5 can be single group or many groups, support 6 is fixed pulley group 5 and linear motor stator electric 7 simultaneously, linear motor stator electric 7 is installed in the inboard both sides of support 6, adopts steel plate structure.Linear motor rotor 8 is equipped with four pairs of miniature rollers, and is installed in the middle of the linear motor stator electric 7, and linear motor rotor 8 and linear motor stator electric 7 are plane structure, and is vertically to arrange, and can move up and down.Rope hanger 3 and linear motor rotor 8 that wire rope 4 connects on the pumping well well heads by sheave block 5, balancer weight 10 are connected the lower end of linear motor rotor 8 and it together moves.Linear motor rotor 8 and balancer weight 10 are installed in the same side of support 6.Rope hanger 3 is connected with polished rod 2 in the well head 1, and wire rope 4 is two parallel connections.At the upper and lower end of linear motor stator electric in 7 snubber 13 is installed, snubber 13 can be two or four, and the turning to of control linear motor rotor 8 is equipped with buffer 14 and leading screw 11 at the upper and lower end of support 6.Leading screw 11 is used for can moving in whole or in part when the oil well operation, abdicates pithead position.Control cabinet 12 is installed in a side of support 6, and the control linear electric motor open machine and stop and changing working system, and power cable 9 is attached thereto.
