Summary of the invention
The purpose of this utility model is to provide a kind of energy-conservation plunger type submersible electric pump extracting device of oil, the existing apparatus structure complexity of solution, the problem that system effectiveness is low, power consumption is high.
The technical scheme of the energy-conservation plunger type submersible electric pump of the utility model extracting device of oil: comprise a plunger displacement pump, it is characterized in that: plunger displacement pump is a stroke fixed distance polyphone linear switched reluctance motor above pumping hole, linear switched reluctance motor is made of with one heart electric motor primary and motor secondary, between motor secondary and the electric motor primary sliding bearing is arranged, motor secondary is the high magnet tube of low-carbon (LC), the iron pipe inner chamber is cylindric, iron pipe covers the layer of metal skin outward, electric motor primary is alternately stacked together at interval by annulus iron core and annulus winding and forms, the electric motor primary fixed outside has end cap and shell, its motor secondary upper end links to each other with petroleum pipeline, petroleum pipeline passes to well mouth of oil well, and the lower end of motor secondary links to each other with the pull bar of plunger displacement pump.
Above-mentioned metal skin is thick copper sheet of 1～2mm or aluminium skin.
Above-mentioned electric motor primary outside is by bolt end cap and shell.
The beneficial effects of the utility model: utilize the linear switched reluctance motor detent torque big, starting current is little, and be applicable to the characteristic of frequent start-stop and reverse conversion operation, make it be applicable to down-hole oil production and oil transportation, motor secondary adopts the high magnet tube of low-carbon (LC), covers thick copper sheet of one deck 1～2mm or aluminium skin outside iron pipe, send the electricity back under the control system preset sequence, motor secondary can reach inverted running up and down to set speed, for plunger displacement pump provides power, and suitable startup thrust is arranged.Plunger displacement pump has the bar oil production method to be fixed in the oil well by tradition, the pull bar of plunger displacement pump is with the secondary operation up and down of linear switched reluctance motor, pump plunger is also corresponding to be moved up and down, and petroleum pipeline by being communicated with cavity and its upper end of motor secondary, pump and oil transportation, constantly crude oil is given rise to the purpose that ground reaches oil recovery.The utility model is direct-connected with motor and pump, the efficient height, can completely abolish the long sucker rod of pumping unit system complicated on the ground and last km, general oil recovery technique is save power significantly, cut down the consumption of energy, also have simple in structure, drive disk assembly is few, the advantage that operate steadily, fault rate is low, the operation of motor secondary and direction can be adjusted as required according to oil production technology, can realize intelligent oil extraction.
