Description
Technical field
The invention belongs to ore pulp-measurings and fluid metering calibration technique field, and in particular to a kind of ore pulp caliberating device.
Background technique
Currently, mainly flowmeter is used to carry out quick metering ore pulp-measuring, flowmeter is mainly ultrasonic flowmeter,
Time difference type and Doppler type can be divided by measuring principle point, ultrasonic flowmeter is propagated in flow media based on ultrasonic wave
Speed is equal to the principle of the mean flow rate of measured medium and the geometry sum of sound wave speed itself and designs.It is also by velocity measurement
To reflect uninterrupted.It receives extensive attention and makes in recent years using the transit time ultrasonic flowmeter that time difference type principle manufactures
With being a kind of most commonly used ultrasonic flowmeter of current enterprises and institutions.The ultrasonic Doppler flow manufactured using Doppler effect
Meter is chiefly used in measuring medium and has certain suspended particulate or bubble medium, using there is certain limitation, but solves the time difference
Formula ultrasonic flowmeter can only measure the problem of single clear fluid, be also considered as the ideal instrument of non-cpntact measurement two-phase flow
Table.Ultrasonic flowmeter used at present has the disadvantage that the temperature measurement range of 1) ultrasonic flowmeter is not high, general
It is capable of measuring the fluid that temperature is lower than 200 DEG C, poor anti jamming capability；2) vulnerable to bubble, fouling, pump and the mixed ultrasound of other sound sources
Noise interference influences measurement accuracy；3) straight pipe requires stringent, is preceding 20D, rear 5D, otherwise discreteness is poor, and measurement accuracy is low；
4) uncertainty installed, can bring large error to flow measurement；5) it is accurate to seriously affect measurement because of fouling for measurement pipeline
Degree, brings significant measurement error, or even for instrument without flow indication, reliability, accuracy class be not high (generally when serious
1.5~2.5 grades or so), poor repeatability, service life is short (general precision can only guarantee 1 year)；6) ultrasonic flowmeter is logical
Measurement fluid velocity is crossed to determine volume flow, its mass flow should be measured liquid, instrument measurement mass flow is logical
Volume flow is crossed multiplied by what is obtained after the density of artificial settings, when fluid temperature variations, fluid density is variation, is artificially set
Density value is determined, it cannot be guaranteed that the accuracy of mass flow.Fluid density can only be measured while measuring fluid velocity,
Operation could be passed through, obtain real quality flow value.It is very high that this results in cost, and replacement is very inconvenient, because live
Various problems can be usually met during the installation process, this is just that field maintenance brings difficulty, not only time-consuming, laborious, Er Qieji
Production is easily influenced, especially when the pressure at scene is larger, is less prone to repair.Therefore, this field needs a kind of mark of ore pulp
Mode or device are determined to change present metering method, quickly calculate ore pulp convenient for scene.
