Description
Technical field
The utility model relates to a kind of three cylinder reciprocating borehole pump merit figure test macros, is used for the borehole pump fault diagnosis, belongs to petroleum gas equipment field.
Background technology
Borehole pump is as the important equipment of drillng operation, mainly bears to shaft bottom delivery cycle cleaner for high-pressure drilling fluid when work, be used for flushing manhole at the bottom of, fractured rock, cooling and lubricating drill bit, and landwaste carried returns ground.Abominable because of its complex structure and operating mode, often because causing construction, stagnates abnormal failure in the production, cause larger economic loss.In drillng operation, drilling well pump performance, state, application life are the important deciding factors that rig normally creeps into.Borehole pump mainly is comprised of power end and fluid end two parts.Fluid end mainly is comprised of plunger, cylinder sleeve, pumping cylinder, pump valve, clack box and air bag, and is abominable because of complex structure, operating mode, usually breaks down.With respect to power end, the failure-frequency that fluid end occurs is high, kind is many.For this reason, the borehole pump fluid end is carried out real-time state monitoring and fault diagnosis seems particularly important.
At present, generally adopt vibration test technology that borehole pump is monitored and fault diagnosis.For the moving information of borehole pump fluid end institute vibration measuring, except pump valve cuts out the vibration of generation in turn, also there is multiple vibration source, cross the vibration of pump valve valve clearance generation and the vibration of power end generation etc. such as vibration, flow that the piston impact fluid produces.This will cause there is larger difficulty in borehole pump fluid end Fault Identification, and to the higher requirement of disposal ability proposition of signal, the modeling of diagnostic system is relative complex also.
The diagnosis of borehole pump also rests on the off-line diagnostic phases at present substantially, all is by regularly detecting the borehole pump working condition, off-line analysis diagnostic data, and judgement borehole pump fault.Because fault diagnosis does not have and the real-time control of borehole pump combines, the operating process real-time is poor, can not in time find the borehole pump fault, will affect largely drillng operation efficient.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of three cylinder reciprocating borehole pump merit figure test macros to be provided, to realize the online diagnosis and detection fault to the borehole pump fluid end.
The technical solution of the utility model is:
A kind of three cylinder reciprocating borehole pump merit figure test macros of the utility model mainly are comprised of power sensor, displacement transducer, Dynamic Data Acquiring instrument, microcomputer.On the piston rod of three pumping cylinders of borehole pump fluid end and clip that pull bar is connected, settle respectively a displacement transducer; On the piston rod of three pumping cylinders of borehole pump fluid end, settle respectively a power sensor; In the running of borehole pump, the signal that records by power sensor and displacement transducer is passed to computer through the Dynamic Data Acquiring instrument, obtain the borehole pump measured indicator diagram by interpretation software again, and the fault signature amount of extraction measured indicator diagram, characteristic quantity with the characteristic quantity of measured indicator diagram and the borehole pump fluid end fault indicator card in the fault database is analyzed at last, diagnoses out borehole pump fluid end fault.
Described power sensor adopts resistance strain-gauge transducer, and displacement transducer adopts optical displacement sensor.
By microcomputer and software borehole pump real-time testing data are carried out high speed acquisition, processing, demonstration and fault diagnosis, realized the inline diagnosis to borehole pump fluid end fault.But this system's inline diagnosis goes out the major failure of borehole pump fluid end, comprises cylinder sleeve, Remedy for Piston Damage and wearing and tearing, and the leakage of blow off valve and inlet valve, spring breakage, valve body is stuck or foreign matter such as blocks at the fault.
Advantage of the present utility model: 1, this system diagnoses the borehole pump fluid end by merit figure test macro, and the sensor of employing is power sensor and displacement transducer, so can avoid vibrating in the vibration test technology impact on signal; 2, this system can detect rapidly particular location, the degree of borehole pump fluid end fault accurately, avoids fault to enlarge and causes larger economic loss; 3, have simple in structure, cost is low, accurate high characteristics.
