Description
Technical field
The utility model relates to fluid flow electronic scales collimation technique field, is a kind of multi-stage loading system of electronic scales standard specifically.
Background technology
Electronic scales is the main standard device in mass method liquid flow standard device, and the electronic scales standard of traditional quality method liquid flow standard device is made up of as Fig. 1 weighing container, electronic scales.
The effect of electronic scales standard in mass method liquid flow standard device is: using the weighing value of electronic scales as standard metering unit, calibrating or calibration calibrated flowmeter.
Electronic scales standard device principle of work: the liquid flowing through calibrated flowmeter flows into weighing container simultaneously, examines and determine calibrated flowmeter by the contrast of electronic scales.
Electronic scales in electronic scales standard device is more higher leveled measurement standard, and the error of electronic scales is one of principal element of mass method liquid flow standard device uncertainty.The change of its repeatability, stability and indicating value in work, brings direct impact all can to tested flow metering.According to the regulation of national verification code " liquid flow standard device ", electronic scales needs periodic verification or calibration in mass method liquid flow standard device.Calibrating is counted and mostly is 10 most.Except periodic verification, when calibrating occurs abnormal during operation, also need calibration criterion device at any time, therefore can carry out multi-stage loading calibration as required.
When the electronic scales standard of traditional mass method liquid flow standard device is calibrated, by manually standard test weight evenly being removed on electronic scales table top successively, after weighing, counterweight is moved down successively.As 1000kg ~ 30000kg, obviously there is following deficiency in larger electronic scales:
1, the calibration of electronic scales more than 1 ton, the labour intensity of operating personnel is very large, and the counterweight of more than 100kg also needs the utility appliance such as crane fork truck to coordinate.
2, the working time is longer, even has certain potential safety hazard.
For above-mentioned reasons, the calibration to electronic scales is seldom carried out in the calibrating phase.
In real work, increasing user runs into electronic scales standard except periodic verification, when calibrating occurs abnormal during operation, needs calibrated electronic scale standard at any time, and traditional electronic scales standard cannot realize this work.
Utility model content
When electronic scales standard for traditional mass method liquid flow standard device is calibrated, Problems existing and deficiency, provide a kind of multi-stage loading system of electronic scales standard.
The technical scheme that the utility model adopts is:
A multi-stage loading system for electronic scales standard, comprises weighing container and electronic scales, and weighing container and electronic scales are arranged on fixed frame; Also comprise multi-stage loading system;
Described multi-stage loading system by row at the bottom of carrier, multiple extension dish pull bar, multiple counterweight, multiple counterweight, multiple hydraulic jack, multiple to hold, pneumatic system, hydraulic system form;
Described carrier and electronic scales affixed; Described carrier is quadra, and quadra is divided into two and arranges identical link code district, and a link code district is provided with many horizontal link code grooves and many vertical link code grooves, is provided with an extension dish pull bar in each horizontal link code groove; Two extension dish pull bars are provided with in each vertical link code groove; Carrier is run through by the affixed disk stop bit of end in link code groove in described extension dish pull bar upper end; Bottom described a pair extension dish pull bar, correspondence is connected with at the bottom of a counterweight and arranges; At the bottom of a described counterweight, two ends, row bottom are provided with two hydraulic jack, and this hydraulic jack drives lifting by hydraulic system; Row bottom correspondence at the bottom of a described counterweight is provided with two ground and holds, and this ground holds and drives to-and-fro movement by pneumatic system.
The utility model has the advantages that:
The utility model, on traditional electronic scales standard calibration basis, overcomes the deficiency that general (single-stage) loads, adds multi-stage loading system; Can load electronic scales at any time, any time section after work carries out automatic, semi-automatic loading; Load calibration operation safe, quick and easy, reliable.
