Description
Technical field
The utility model is a kind of analyzer of water content, is applied to oil field oil recovery, gathering-transferring technology field, measures the instrument of water percentage in the oil well output crude oil.It is a kind of water in oil analyzer that can remove crude oil water containing sensor surface greasy dirt automatically.
Background technology
In oilfield process, contain water in the crude oil of output, need carry out the water percentage analysis to output crude oil.The profit analyser that uses is that the crude oil water containing sensor is directly inserted in the pipe laying now, water percentage in the online detection crude oil.Because the content of wax in the crude oil, the viscosity height, use a period of time after, crude oil water containing sensor surface wax deposition adheres to crude oil, and sensor can not fully be contacted with detected crude oil, causes sensor signal untrue.Operating personnel need often to clean sensor, and influence is produced.That Chinese patent 00212739 discloses is a kind of " erasing type water content in oil sensor automatically ", has realized that sensor can to-and-fro movement in wiping cover, wipes the sensor surface dirt, does not need to dismantle pipeline, does not influence production, and the signal of assurance sensor is accurate.This " automatically erasing type water content in oil sensor " by the elevating mechanism of wiping the sensor surface greasy dirt, wipe control circuit automatically and the crude oil water containing sensor is formed.It is characterized in that wiping the elevating mechanism of sensor surface greasy dirt by the continuous support column of motor cabinet, support column is connected with flange, be connected with clutch coupling with motor, be connected with threaded connector by shaft coupling and clutch coupling, be connected with screw by thrust bearing and last screw thread, have and be contained in the screw and the thread slider of lower hollow, have and be contained in the miniature magnet steel in the fixed orifice on the thread slider housing, the upper limit that is contained in bar hole upper and lower side corresponding with miniature magnet steel on the support column is arranged near switch, lower limit is near switch, the following threaded connector that links to each other with thread slider is arranged, the heart yearn pillar that links to each other with following threaded connector and pass flange is arranged, the nipple that links to each other with sensor with the heart yearn pillar is arranged respectively, the cover of polishing that is fixed between guard shield and the outer cover is arranged.Automatically wipe control circuit by upper and lower spacing near switch and input end connect, lower limit constitutes near the positive and negative control circuit of motor of switch, output termination micromotor and the timing circuit of control micromotor work.
In the elevating mechanism of " automatically erasing type water content in oil sensor ", used upper limit near switch and lower limit near switch.Motor positive and inverse control is spacingly to be changeed anyway near switch control motor by upper and lower, reaches the purpose of restriction adjustable height.This structural circuit complexity, up stroke is controlled near switch by upper limit; Down stroke is controlled near switch by lower limit.Upper and lower spacingly go wrong near switch, upper and lower spacing near malfunctioning switch, can cause micromotor ceaselessly a direction rotate, elevating mechanism can't operate as normal, the purpose of wiping the sensor surface dirt can't realize.Sometimes may burn motor, whole elevating mechanism is in paralysis.
Summary of the invention
The purpose of this utility model is, changes in existing " erasing type water content in oil sensor automatically " elevating mechanism, and the SC service ceiling position is near switch and the lower limit structure near switch.Solve upper and lower spacing near malfunctioning switch, cause micromotor ceaselessly direction rotate, elevating mechanism can't operate as normal, wipes the shortcoming that the purpose of sensor surface dirt can't realize.The lifting position-limit mechanism of the structure that designs a mechanism guarantees to wipe dirt in crude oil water containing working sensor surface everything goes well with your work to finish.Improve the accuracy of the signal of sensor.
The utility model is made up of crude oil water containing sensor, sensor holder, the elevating mechanism of wiping the sensor surface greasy dirt, secondary instrument and micromotor work timing circuit, the crude oil water containing sensor is enclosed within the center pit of sensor holder with polishing, and polishing is enclosed within the periphery of crude oil water containing sensor.It is characterized in that: wiping in the elevating mechanism of sensor surface greasy dirt has support tube, and support tube one end is fixed on the sensor holder.The support tube other end has pressure cap.Pressure cap connects support tube and motor fixing frame.Motor is fixed in the fixed mount.By shaft joint motor is connected with leading screw.Leading screw has the screw rod sliding sleeve outward, and screw rod sliding sleeve inwall has ring groove.Ball and ball rack are arranged between screw rod sliding sleeve and the leading screw.Ball can roll between ring groove and threads of lead screw.Last register pin is arranged at leading screw top, and there is following register pin the lower end of leading screw.Screw rod sliding sleeve bottom connects the leading screw tube, during forward and reverse rotations of leading screw, and the upper and lower thereupon slip of screw rod sliding sleeve drive leading screw tube.Leading screw tube bottom connects the crude oil water containing sensor, and the motion of leading screw tube drives sensor upper and lower motion in the cover of polishing, and the cover of polishing is wiped the dirt of sensor surface.
In the above-mentioned elevating mechanism of wiping the sensor surface greasy dirt, in order to improve rising or falling speed, leading screw can be processed into two threaded screw rods.
For screw rod sliding sleeve reliable operation, screw rod sliding sleeve Nell wall ring groove quantity is 2-5.Corresponding ball is 2-5 row.
Convenient for the dismounting elevating mechanism, have between motor fixing frame and the leading screw slideway to connect the oily ninth of the ten Heavenly Stems.
In order to protect sensor not to be bruised, under the sensor holder, be connected with the sensor urceolus.Be fixed with to scrape in the sensor lower end and cover with paint or varnish, when the upper and lower motion of sensor, scrape and cover with paint or varnish the dirt that to remove on the sensor outer tube inner wall.Frizing has brushed " O " shape O-ring seal, and frizing is cleaner.
Effect of the present utility model is tangible.Changing the upper and lower motion of limit switch control leading screw is the upper and lower range of mechanical type control leading screw.Commentaries on classics anyway with timing circuit control micromotor.Even motor was rotated further when the screw rod sliding sleeve ran to topmost, ball is along the inwall ring groove rotation of screw rod sliding sleeve, and screw rod sliding sleeve and leading screw tube do not move, and can not produce the burn-down of electric motor accident.Otherwise the screw rod sliding sleeve runs to bottom, and motor is rotated further, and equally also can not produce the burn-down of electric motor accident.Overcome upper and lower spacing near malfunctioning switch, can cause micromotor ceaselessly direction rotate the shortcoming that elevating mechanism can't operate as normal.
