(2) magnetostriction apparatus is installed
1) fluid reservoir is installed
At first determine the level line of each measuring point according to designing requirement, all fluid reservoir 3 containers are arranged on identical absolute altitude position (this is very important) before monitoring facilities begins.The erecting frame 6 use expansion bolts that then will install three adjusting bolts are fixed on contour survey pier or on metope, again fluid reservoir 3 is arranged on adjusting bolt 5, utilizes the nut on spirit bubble 14 adjusting screw(rod)s that are positioned on fluid reservoir 3 upper end covers to make fluid reservoir base plate 4 keep the approximate horizontal state.
Erecting frame is " L " shape steel plate, and one side has hole, the center of 3 ￠ 9 to have the hole when installing (survey pier with) of 1 ￠ 11, another side that the hole (when metope is installed with) of 2 ￠ 11 is arranged.The hole of ￠ 9 is used for installing adjusting bolt, and the hole of ￠ 11 is used for fixing and mounting bracket.Erecting frame is fixed with the survey pier or is all selected the expansion bolt of M10 to fix with metope is fixing, and expansion bolt is fixedly tightened the back nut gluing and fixed.
2) connect fluid-through tube
To be arranged on the liquid storage cylinder of 1 pipe adapter first measuring point and last measuring point when fluid reservoir 3 is installed, all the other measuring point liquid storage cylinders all are with 2 pipe adapters.
According to the distance between each measuring point, then the length of intercepting fluid-through tube join the fluid-through tube mouth of pipe and pipe adapter and use locked clip device, and each measuring point is cascaded, and carries out at last that fluid-through tube is fixed and Protection.
3) fluid reservoir topping up
Screw off the upper end cover of any one fluid reservoir 3, the anti freezing solution (can add a small amount of glycerine, prevent from evaporating) of buying is filled with static liquid level.
During operation, can only be from selected unique fluid reservoir liquid feeding, liquid feeding is continual adding slowly, air and the bubble in drain fully, the interior liquid level of continuous observing system is when stopping topping up after the liquid level equilibrium in all fluid reservoirs and when reaching graticule.
The sealing property of check system, observing fluid reservoir and each joint area has no liquid to ooze out, and can carry out next step operation without any seepage.
4) tank gage is installed
First fluid reservoir 3 upper end covers are screwed off, again the position-arresting ring 19 on magnetostriction liquidometer 1 measuring staff 17 is unloaded, take off float 18, then measuring staff 17 is inserted in fluid reservoir 3 upper end cover M18 * 1.5 threaded holes and screw, again the float 18 that takes off is resetted (hemisphere of CN mark being arranged on liquid level) by former direction, position-arresting ring reset (be fixed on apart from measuring staff end approximately 19mm place) get final product.Fluid reservoir 3 upper end covers that will install at last magnetostriction liquidometer screw.
5) connect snorkel
The ventilation effect be that all liquid level pressure are consistent, whole aerating system should be interconnected and only on one point (one is selected at two ends) be communicated with atmosphere.
Tracheae on the arbitrary liquid storage cylinder in system two ends is connected with drying tube, connects the open to atmosphere end three-way connection of drying tube, other end quarter bend pass joint.
According to the distance between each measuring point, then the length of intercepting snorkel join the snorkel mouth of pipe and pipe adapter, and each measuring point is cascaded, and is communicated with atmosphere by drying tube, carries out that snorkel is fixed and Protection.
(3) reading
When magnetostriction apparatus is measured:
1) manually image data can use GN-103A type readout instrument to measure that (front 4 figure places of modulus F=are because of the sensitivity of this instrument≤0.001mA).
2) automatic data acquisition can use the automatic measuring unit of MCU-32 distributed modular to measure.
(4) calculate
In system, each instrument liquid level changes and can calculate by following formula:
ΔELx＝Kx(Fix-Fox)+Kj(Fij-Foj)
This: the liquid level variable quantity (mm) of Δ ELx=instrument
The current reading (F) of Fix=instrument
The initial reading of Fox=instrument (F)
Kx=instrument sensor coefficient (mm/F)
The current reading (F) of Fij=reference point instrument
The initial reading (F) of Foj=reference point instrument
Kj=reference point instrument sensor coefficient (mm/F)
Annotate: apparatus measuring value Δ ELx on the occasion of the time be expressed as rising, Δ ELx is expressed as sedimentation when being negative value.
(5) temperature correction
Temperature variation in normal range of operation is very little on the measured value impact of sensor, all less than least count, all ignores temperature and need not revise the impact of sensor under normal operation.
