The features such as that advantage of the present invention is that power supply has is independent, stable, low pressure, avoid the circuit in sensory-perceptible system to be broken down by high-voltage, and reduction of service life, do not affect mode of operation and the duty of original oil immersion line motor. When operation, self-generating provides power supply, has reduced electronic component, reduces the fault rate of device, the service life of having improved oil immersion line motor liquid-level measuring-controlling apparatus. Realized intelligent, high precisely, real-time Transmission, unmanned.
Description
Technical field
The invention belongs to a kind of underground liquid level measure and control device, particularly oil immersion line motor underground liquid level checkout gear.
Technical background
At present, the general oil recovery machiner that adopts oil pumper, sucker rod and oil well pump to form both at home and abroad recovers the oil, existing oil recovery machiner exists volume large, cost is high, reactive loss is large, the shortcoming such as easily break down, the one " reciprocating submersible electric pump " (Chinese invention patent number: ZL200410050431.5) of research and development has changed the artificial lifting way of oil extraction for this reason. This reciprocating submersible electric pump is suitable for the mining of oil, gas, water. Current oil field and coal bed gas detect down-hole liquid level mode and adopt sonic test method more, and the method is difficult to guarantee accuracy of detection, therefore urgently provide a kind of intellectuality, high liquid-level measuring-controlling apparatus accurately to meet the needs in present market.
Analyze technically, because oil production equipment adopts high-voltage large current power supply more, if the required power supply of sensor-based system takes out from oil immersion line motor is inner, motor is done the used time and cannot be detected insulation going into the well, and, because the each unit original paper in pressure capsule system adopts low pressure original paper more, can not bear the high pressure of oil immersion line motor work, therefore the power supply of downhole sensor needs low pressure, isolation, DC voltage-stabilizing, the normal work of guarantee sensor; Simultaneously, can not be that downhole sensor separately descends power line, be lowered to if the cable of the power supply line of sensor and electric pump is parallel, the power supply line of sensor disturbs the cable heavy current that is subject to electric pump, cannot extract faint detectable signal, be a technical barrier so the power supply of downhole sensor is supplied with all the time.
Summary of the invention
The object of this invention is to provide a kind of oil immersion line motor liquid-level measuring-controlling apparatus, electric supply installation can meet that sensory-perceptible device is stablized, the requirement of pure supply voltage, avoid the circuit in sensory-perceptible device to be broken down by high-voltage, reduction of service life, the problem that cannot normally work. Realize intelligent, high precisely, real-time Transmission, unmanned.
The object of the invention is to be achieved through the following technical solutions: the tail pipe, the motor permanent magnetism mover that comprise oil immersion line motor, it is characterized in that: at oil immersion line motor tail pipe outer shroud place, place one with cored coil windings near oil immersion line motor stator bottom, the current output terminal of coil windings connects pressure sensor bottom by regulator rectifier circuit, the outside assembling of pressure sensor balance capsule.
Good effect of the present invention: 1, power supply mode of the present invention provides sensory-perceptible system stability, pure supply voltage, there is the features such as independent, stable, low pressure, avoid the circuit in sensory-perceptible system to be broken down by high-voltage, reduction of service life, the difficult problem that cannot normally work. 2, System Controlled by Measuring Pressure and oil immersion line motor system are all to have accomplished isolation completely at power supply supply respect or side signal transmission face, because adopting, transmission exchanges high-frequency mode, data transmission central's frequency reaches 120KHZ, far away higher than the frequency of electrical source of power, therefore adopt Capacitor apart mode, use original power cable as holding wire, frequency signal is transferred to ground, in this process, can not affect oil immersion line motor and normally work. So this covering device does not affect mode of operation and the duty of original oil immersion line motor. 3, when this device utilizes oil immersion line motor operation, self-generating provides power supply, has reduced electronic component, reduces the fault rate of device, the service life of having improved oil immersion line motor liquid-level measuring-controlling apparatus. 4, realized intelligent, high precisely, real-time Transmission, unmanned.
Brief description of the drawings
Fig. 1 is the concrete schematic diagram of oil immersion line motor liquid-level measuring-controlling apparatus.
Fig. 2 is oil immersion line motor liquid-level measuring-controlling apparatus electrical schematic diagram.
Detailed description of the invention
See Fig. 1, concrete structure is as follows: at the tail pipe 6 outer shroud places of oil immersion line motor 1, place one with cored coil windings 4 near oil immersion line motor stator 2 bottoms, coil windings 4 connects rectification circuit plate 9 by probe power cable 5, rectification circuit plate 9 connects pressure sensor 8 bottom, the outside assembling balance capsule 7(prior art of pressure sensor 8).
See Fig. 2, measure and control device circuit theory: by coil windings 4(L) make with the permanent magnetism mover 3 of oil immersion line motor the alternating voltage that cutting magnetic induction line motion produces and be rectified into DC voltage by silicon bridge Z, passed through again capacitor C 1, C2 filtering, storage, make it stable output DC voltage, supplying with pressure sensor 8 works, the signal of detection is transferred to linear electric motors asterism 10 by pressure sensor 8, is coupled on linear electric motors asterism and with motor housing and formed loop by capacitor C 3.
Operation principle: have permanent magnet and iron core interval on the permanent magnetism mover 3 of oil immersion line motor and the composition N utmost point and the S utmost point, in the reciprocating process of permanent magnetism mover 3, the magnetic line of force of sectioned coil winding 4 produces induced electromotive force, electric current provides pressure sensor 8 to carry out work after by rectifying and voltage-stabilizing, pressure sensor 8 is sent to ground master control system by the detectable signal of perception down-hole pressure by linear electric motors asterism 10, oil immersion line motor 1, power cable, also can realize network well logging by radioing to master-control room. At the balance capsule 7 of the arranged outside of pressure sensor 8, make pressure sensor 8 and liquid isolated, thereby protected pressure sensor 8.
