Abstract
Description
Technical field
The technology belongs to pressure calibration field, and in particular to a kind of high-pressure gas pressure field calibration method.
Background technology
High-pressure gas pressure pressure instrumentation is widely used in defence and military system, the measurement range of pressure sensor used The upper limit reaches more than 70MPa.Pressure is high, dangerous big, to the standard of high-pressure gas pressure sensor measurement data during experiment True property requirement is very high, is related to type product quality.Therefore, it is necessary to essence is carried out to used high-pressure gas pressure sensor True calibration.The field calibration demand of the high-pressure gas pressure instrument of model experiment in recent years is more and more.But this method is deposited In problems：
(1) dismounting, due to the limitation of environmental condition, influences measurement data accuracy to laboratory investment；
(2) dismounting easily damages the hickey of manometer, influences equipment use；
(3) high-pressure gas pressure sensor can only be calibrated, it is impossible to which the high-pressure gas pressure including acquisition system is surveyed Amount system is calibrated；
(4) the laboratory investment cycle is longer, influences unit use.
Due to these shortcomings, there is an urgent need to innovate calibration method, carry out field calibration.
The content of the invention
It is an object of the invention to：A kind of high-pressure gas pressure field calibration method is provided, solves puzzlement gases at high pressure pressure Power calibrating indicating instrument and the problem used ensure under site environment, the accuracy of high-pressure gas pressure instrument measurement data.
Technical scheme is as follows：A kind of high-pressure gas pressure field calibration method, comprises the following steps
S1:Standard is started shooting, and standard includes pressure measuring module, digital pressure gauge, high-pressure gas pressure field calibration Device；
S2:Closing is calibrated high-pressure gas pressure instrument isolating valve, and standard access is calibrated high-pressure gas pressure instrument The special calibration interface of table accesses standard in the pipeline being calibrated near high-pressure gas pressure instrument；Or it will be calibrated High-pressure gas pressure instrument is disassembled from operating position, selects suitable connecting tooling, will be calibrated high-pressure gas pressure Instrument is installed on high-pressure gas pressure field calibration device, it is ensured that sealed reliable；
S3：Calibration point is uniformly chosen being calibrated in the range ability of high-pressure gas pressure instrument real work
S4:Calibration；
S4.1:Reading is calibrated high-pressure gas pressure instrument zero-bit indicating value, and if desired zeroing operates, then carries out zeroing behaviour Make；
S4.2:Pressure is smoothly adjusted successively since being calibrated the lower limiting value of high-pressure gas pressure instrument to choose into S3 Each calibration point, read and record the output valve for being calibrated high-pressure gas pressure instrument and standard, until upper pressure limit value, be Complete a pressure calibration process.
, it is necessary to preheating more than the 30min that is powered in S1.
In S3, calibration point is included within zero point, range higher limit, lower limiting value or neighbouring 10% input range, inside much In 3 points；If the lifting of pressure can not be realized by being calibrated high-pressure gas pressure meter locale, gases at high pressure pressure is being calibrated The pressure spot of power instrumentation carries out the calibration of 1 pressure spot.
S4.3 is further included after S4.2:3 pressure calibration processes should be at least carried out continuously.
The remarkable result of the present invention is：With preferable practicability and operability, high-pressure gas pressure can be used as Instrument carries out the method that field high pressure gas pressure magnitude is traced to the source.
Specific embodiment
A kind of high-pressure gas pressure field calibration method, comprises the following steps
S1:Standard is started shooting, and standard includes pressure measuring module, digital pressure gauge, high-pressure gas pressure field calibration Device, (from power) need preheating more than the 30min that is powered；
S2:Closing is calibrated high-pressure gas pressure instrument isolating valve, and standard access is calibrated high-pressure gas pressure instrument The special calibration interface of table accesses standard in the pipeline being calibrated near high-pressure gas pressure instrument；Or it will be calibrated High-pressure gas pressure instrument is disassembled from operating position, selects suitable connecting tooling, will be calibrated high-pressure gas pressure Instrument is installed on high-pressure gas pressure field calibration device, it is ensured that sealed reliable.
S3：The selection of calibration point
Calibration point should uniformly be chosen being calibrated in the range ability of high-pressure gas pressure instrument real work, and (from power) should 3 points are no less than including zero point, range higher limit, lower limiting value (or within neighbouring 10% input range).If it is calibrated High-pressure gas pressure meter locale can not realize the lifting of pressure, then be calibrated the pressure spot of high-pressure gas pressure instrumentation Carry out the calibration of 1 pressure spot.
S4:Calibration
S4.1:Reading is calibrated high-pressure gas pressure instrument zero-bit indicating value, and if desired zeroing operates, then carries out zeroing behaviour Make；
S4.2:Pressure is smoothly adjusted successively since being calibrated the lower limiting value of high-pressure gas pressure instrument to choose into S3 Each calibration point, read and record the output valve for being calibrated high-pressure gas pressure instrument and standard, until upper pressure limit value, be Complete a pressure calibration process；
S4.3:(from power) should at least be carried out continuously 3 pressure calibration processes.
