Abstract
The utility model relates to a high-precision measuring device for the water percentage of crude oil. The probe head point of a sensor is provided with an erasing slice, and the erasing slice is connected with a motor through a reciprocating motion mechanism. The motor is connected with a controller, and the erasing slice is matched with the cylindrical surface of the probe head. When the utility model works, the controller sends signals out to the motor to make the motor started one time for every certain time, and the motor makes the erasing slice move in a reciprocating mode along the surface of the probe head through the reciprocating motion mechanism. The impurities, such as wax, alkali, sand, etc. accumulated on the surface of the probe head can be cleaned out in time, the cleaned probe head can be always sufficiently contacted with measured mediums, and the sensibility and the measurement precision of the sensor can be ensured.
Description
The utility model belongs to the technology of instrument and meter field, is a kind of crude oil water content analyzer.
At present, the analyzer of the monitoring crude oil water content that domestic petrochemical industry is used is by the column probe of sensor, adopt the shortwave absorption process, utilize water percentage to absorb the relation that energy is directly proportional with shortwave, change electric signal again into, flow to microprocessor, calculate parameters such as water percentage, oil mass, the water yield.But, owing to contain impurity such as a large amount of wax, alkali, sand in the crude oil, behind the working sensor certain hour, will amass knot at detecting head surface, cause the water cut monitor distorted signals and influence measuring accuracy.
The purpose of this utility model is will provide a kind of can remove detecting head surface, thereby can guarantee the crude oil water content analyzer of monitoring accuracy.
Solution of the present utility model is to be provided with at the sensor probe place to wipe sheet, wipes sheet and is connected with motor by reciprocating mechanism, and motor is connected with controller, wipes sheet and matches with the cylindroid of probe.During work, at regular intervals, controller sends signal to motor, make motor start-up once, motor by reciprocating mechanism make wipe sheet along the probe the surface move back and forth, impurity such as the wax of long-pending knot on detecting head surface, alkali, sand are in time removed, the clean probe of cleaning is fully contacted with measured medium all the time, guaranteed the sensitivity and the measuring accuracy of sensor.
The utility model can guarantee monitoring accuracy, goes slick, easy to maintenance dependable performance.
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing is the utility model synoptic diagram.
The utility model is made of main frame 1 and probe 2, what be provided with annular at probe 2 places wipes sheet 3, wiping sheet 3 is connected with motor 9 by reciprocating mechanism, motor 9 is connected with controller 11, wiping sheet 3 matches with the cylindroid of probe 2, wherein reciprocating mechanism is by screw mandrel 6, screw 5, guidepost 7 and wipe bar 4 and constitute, the output shaft of motor 9 connects screw mandrel 6 by a clutch coupling 8, screw mandrel 6 is a left-right turning screw rod, screw 5 is enclosed within on the screw mandrel 6 and with guidepost 7 and cooperates installing, screw 5 is wiped sheet 3 by wiping bar 4 connections, motor 9 receives the signal of controller 11 transmissions and starts working, its output shaft drives screw mandrel 6 rotations, screw 5 is that track pumps with guidepost 7 under the effect of screw mandrel 6, and drives and wipe sheet 3 and move back and forth on the surface of probe 2 by wiping bar 4, and limit switch 10 is housed on motor 9, reciprocating number of times when may command is wiped sheet 3 and wiped at every turn makes motor 9 stop operating automatically after the work.Reciprocating mechanism also can be wiped bar 4 by the cam connection and constitute, and also can wipe bar 4 by the linkage assembly drive and constitute, and can also adopt reversing motor, thereby left-right turning screw rod can change single rotation direction leading screw into.
