Blue elephant adopts the drive path of switched reluctance machines commutation, electromagnetic brake, cycloidal-pin wheel deceleration, directive wheel guiding mostly simultaneously.Find to exist cycloidal-pin wheel reducer fault rate height and influence reliability through field test; During well workover simultaneously, need remove part oil pumper parts equally, for difficulty has been added in workover treatment.
Technology contents
The purpose of this utility model is: the direct balanced oil extractor that provides a kind of switched reluctance machines to drive, can realize commutation by switched reluctance machines; Do not shut down the adjustment operational factor; Do not need mobile complete machine just can abdicate the well workover position, and have the blue elephant that volume is little, in light weight, dynamic load is little, well workover is convenient in power consumption less.
The utility model purpose is achieved in that the direct balanced oil extractor that switched reluctance machines drives comprises belt pulley, belt, switched reluctance machines, working platform, bracing frame, balance weight, friction roll, bearing bracket stand, wire rope, guide pulley, bearing, polished rod eye, electromagnetic brake.The bracing frame top is fixed with working platform.It is characterized in that: be fixed with switched reluctance machines on working platform, switched reluctance machines has driving and commutation function.Be connected with electromagnetic brake and belt drive unit on the power output shaft of switched reluctance machines, drive the positive and negative rotation of friction roll by belt drive unit.Belt drive unit plays driving torque and decelerating effect.Belt drive unit comprises two belt pulleys and belt.Top at working platform is fixed with bearing bracket stand, and main shaft is arranged on the bearing bracket stand, connects on the main shaft and is supported with belt pulley and friction roll.Edge at working platform is fixed with bearing, is fixed with guide pulley on the bearing.Wire rope is walked around friction roll and guide pulley, and wire rope one end connects balance weight, and the other end connects polished rod eye.Balance weight is hung vertically in the bracing frame inside casing.Switched reluctance machines is realized running anyway under the control of switch board, friction roll and guide pulley are reciprocating by driving wire rope, and rope belt dynamic equilibrium piece and polished rod eye pump, and finish oil extraction operation.
In order to improve stability, switched reluctance machines has the two ends output shaft, connects belt drive unit on the output shaft of two ends respectively.On friction roll and guide pulley, there are two wire rope to walk around.
In order to improve the stability of balance weight, there is directive wheel the both sides of balance weight, adopt the two sides guiding.Balance weight comprises and is divided into the stable equilibrium piece and can adds balance weight.
In order to improve the balance quality of balance weight, described structure of adding balance weight adopts the casing of steel plate welding, and iron sand or blanc fixe are arranged in casing.In casing, add iron sand or blanc fixe, make counterpoise more accurate.
The beneficial effects of the utility model are: the direct balanced oil extractor that switched reluctance machines drives, exchange system are to be realized by switched reluctance machines and switch board.Balance sysmte balance weight rectilinear motion, the balance weight guiding adopts two-sided guiding, is divided into fixed weight piece and adjustable weight balancing weight.Brake system adopts electromagnetic brake, can realize a little stopping.Bearing and guide pulley can be lifted and overturn during workover treatment, do not need mobile complete machine just can abdicate the well workover position.The direct balanced oil extractor that switched reluctance machines drives can be realized stroke and jig frequency parameter step-less adjustment, adapts to different well ' s conditions; the adjustment mode adopts turn-knob and button control, and is easy and simple to handle, adjusts the precision height; do not shut down the adjustment operational factor, monitor other outer operational factors of polished rod load in real time.
