Abstract
A liquid level measurement and control apparatus for a submersible linear motor comprises a tail tube and a motor permanent magnet mover of the submersible linear motor. The liquid level measurement and control apparatus is characterized in that a coil winding with an iron core is disposed at the outer ring of the tail tube and close to the lower end portion of the stator of the submersible linear motor, the current output terminal of the coil winding is connected a pressure sensor at the lowest end through a rectification voltage stabilizing circuit, and a balance capsule is assembled outside the pressure sensor. The advantages are provided as follows: power supply is characterized by being independent, stable, low in voltage, etc., the circuit in the sensing system is protected from high-voltage breakdown phenomenon, the service life is long, and the work mode and work state of the prior submersible linear motor are not affected. When the liquid level measurement and control apparatus runs, power is supplied by self generation, the number of electronic components is reduced, the failure rate of the apparatus is decreased, and the service life of the liquid level measurement and control apparatus for the submersible linear motor is prolonged. The apparatus realizes intellectualization, high accuracy and real-time transmission, and unmanned operation is available.
Description
Technical field
The utility model 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, a kind of " reciprocating submersible electric pump " (Chinese utility model patent number: ZL 2,004 1 0050431.5) of research and development have changed the artificial lifting way of oil extraction for this reason.The row that this reciprocating submersible electric pump is suitable for oil, gas, water adopts.Current oil field and coal bed gas detect down-hole liquid level mode and adopt the 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 the 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 can't be detected insulation going into the well, and, because each unit original paper in pressure capsule system adopts the 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 operation of guarantee transducer; Simultaneously, can not separately descend power line for downhole sensor, if the cable of the power supply line of transducer and electric pump is parallel, be lowered to, the power supply line of transducer will be disturbed by the cable heavy current of electric pump, can't extract faint detectable signal, be a technical barrier so the power supply of downhole sensor is supplied with all the time.
The utility model content
The purpose of this utility model is to provide a kind of oil immersion line motor liquid-level measuring-controlling apparatus, electric supply installation can meet that the sensory-perceptible device is stablized, the requirement of pure supply voltage, avoid the circuit in the sensory-perceptible device to be broken down by high-voltage, reduction of service life, the problem that can't work.Realize intelligent, high precisely, real-time Transmission, unattended operation.
The purpose of this utility model is achieved by the following technical solution: 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 utility model: 1, supply power mode of the present utility model provides sensory-perceptible system stability, pure supply voltage, there are the characteristics such as independent, stable, low pressure, avoid the circuit in the sensory-perceptible system to be broken down by high-voltage, reduction of service life, the difficult problem that can't work.2, System Controlled by Measuring Pressure and oil immersion line motor system are all to have accomplished isolation fully 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 the Capacitor apart mode, use original power cable as holding wire, frequency signal is transferred to ground, can not affect the oil immersion line motor normal operation in this process.So this covering device does not affect mode of operation and the operating state of original oil immersion line motor.When 3, this device utilizes the oil immersion line motor operation, self-generating provides power supply, has reduced electronic component, reduces the failure rate of device, the useful life of having improved the oil immersion line motor liquid-level measuring-controlling apparatus.4, realized intelligent, high precisely, real-time Transmission, unattended operation.
The accompanying drawing explanation
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.
Embodiment
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, the pressure sensor 8 that rectification circuit plate 9 connects 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 the cutting magnetic induction line motion produces and be rectified into direct voltage by silicon bridge Z, again it is passed through to capacitor C 1, C2 filtering, storage, make it the stable output direct voltage, supply with pressure sensor 8 work, pressure sensor 8 is transferred to linear electric motors asterism 10 by the signal of detection, by capacitor C 3, is coupled on the linear electric motors asterism and with motor housing and forms loop.
Operation principle: permanent magnet and iron core interval are arranged and the composition N utmost point and the S utmost point on the permanent magnetism mover 3 of oil immersion line motor, 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 the 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 the network well logging by radioing to master-control room.At the balance capsule 7 of the arranged outside of pressure sensor 8, make sensing probe and liquid isolated, thereby protected pressure sensor 8.
