During concrete operations, input on computers this time detecting information; Close draining after pressure testing device 1 is rinsed well, to the water jacket water filling, water is annotated suitable height, do not overfill as suitable to put into pressure testing bottle 2 rear water; The factory number of institute's mark on the trial jar will be treated, nominal operating pressure, test pressure, the gas cylinder quality, gas cylinder volume, manufacturer, the date of production, on the typings such as the gas cylinder affiliated unit control computer, when need obtain the actual weight of gas cylinder and volume by wireless steelyard, need to click " wireless weighting " button on the computer screen, eject dialog box, current weighing data has shown the actual weight of alleged object on the wireless steelyard, the user at first hangs over empty bottle on the wireless steelyard hook, after registration is stable, click first " setting " button on the computer screen, empty bottle weight is set, after empty bottle is weighed and is finished, in gas cylinder, add water, until fill it up with, this moment, current weighing data changed, after registration is stable, " " button can the automatic acquisition gas cylinder volume in setting to click second, this data communication device is crossed and is subtracted each other and obtain adding behind the water the heavy and empty bottle weight of bottle, that is: heavy-empty bottle is heavy altogether for gas cylinder volume=bottle water, at last, click " determining " button, can be with this data automatic input to gas cylinder weight and actual volume zone.Click " preservation information " or " load information " button, can eject the gas cylinder information parameter and preserve or load window; The user can preserve or load by selecting the data corresponding with gas cylinder; Pressure testing bottle graft head 8 is torqued-up on the pressure testing bottle 2 of filling water, and is connected with water jacket plug 12, the pressure testing bottle 2 of slinging is hung into water jacket 11 with it, and water jacket plug 12 is fastened on the water jacket 11.Open part valve, the water that the pressure-bearing flexible pipe that is connected with articulation 9 flows out adds articulation 9 to full, closely is connected rear shut-off valve 16 with articulation 9 again.Without leakage, can before hanging in water jacket, pressure testing bottle 2 connect first in case of necessity pressure-bearing pipe pressurization leak detection in order to ensure system; Then carry out water jacket 11 exhausts, the valve that is connected with gas outlet is opened in measuring cup 32 water fillings, and with T-valve 7 tangential drainage position, open valve 15 again, the valve that shut-off valve 15 is connected with gas outlet after water flows out from the valve that is connected with gas outlet.With T-valve 7 tangential location of water injection, slightly open valve 15, test water is injected into measuring cup 32, adjusts measuring cup inner storing water amount between 250～300g, and guarantees that the water filling mouth of pipe is dipped into about the following 20mm of surface level shut-off valve 15; Leave standstill again, read the indicating value of balance 31, leave standstill and observe indicating value behind the 30S and whether change.If the constant displayed value that then records.If displayed value descension theory open fire cover system has leakage, there is leakage water intaking valve inside if displayed value rises then, must continue after the eliminating leakage again; Carrying out the hydraulic testing, " current pressure " shown the dynamic pressure numerical value in the test process on the computer screen, and " Current Temperatures " shows the dynamic temperature in the test process, and " gas cylinder deflection " zone is according to current test mode one of four states such as (comprise) boosting, pressurize, pressure release, the wait water yield are stable, " water yield dynamic value " is synchronous with balance 31 data, shows the real data of balance 31; " water yield reference value " shows the supercharging water yield value of the zero hour, it becomes dilatational strain amount after the gas cylinder supercharging or the residual deformation amount after the pressure release with the difference of " water yield dynamic value ", " maximum deformation quantity " reaches maximum deformation value after the set pressure for gas cylinder, and " residual deformation amount " is that gas cylinder is in pressurize, residual variate after the pressure release, " gas cylinder rate of residual " calculates automatically: residual variability=residual variable/maximum deformation quantity * 100%, there are three kinds of displaying schemes optional in " curve type " zone: pressure-time, inflow-time, pressure-inflow curve scheme.Select the rear corresponding performance graph that just shows in the viewing area.Test pressure and dwell time are set in " test parameter " zone, after after test parameter is set, click START button and can carry out the hydraulic testing, after START button is clicked, the user need open " test pump feed water valve ", and can normally be the gas cylinder supercharging this moment.After pressure of the inside of a bottle reached set pressure, system can stop test automatically, enters pressure maintaining period.Leak if in pressure maintaining period, exist, system can judge automatically, and in " system message " if the zone provides relevant prompting system without leakage, can carry out the pressurize countdown in " system message " zone, after finishing pressurize, " system message ' the zone meeting prompting user packing setting dwell time; and require the user to carry out pressure release; at this moment; the user needs manual unlocking " pressure release back-water valve (BWV) " to carry out the gas cylinder pressure release, have suggested this moment in " system message ", after the pressure of the inside of a bottle pressure release is made zero; this moment, the reading of balance 31 was stablized, and need to wait for a period of time can.After balance 31 data were basicly stable, this time test was finished, and can show corresponding water yield data according to above-mentioned test process in " gas cylinder deflection " zone.After test is finished, click " preservation form " button and carry out form preservation, generating report forms; Unload pressure testing bottle 2, unload lower sub 8 from pressure testing bottle 2.Then calculate the rate of residual volumetric deformation of pressure testing bottle.The verification of outside measurement method test unit: precondition is must have the full deformation values of volume for the standard jar of verification test unit, and the nominal volume of standard jar should equate with the nominal volume of pressure testing bottle or approach.Points for attention: during the setting pressure table, should note the emptying tensimeter and take over interior air.Must remove bump protection ring and any impressed pressure before the gas cylinder by hydrostatic pressure test.If find in the process of boosting that the rate of rise obviously speeds or during the phenomenon that slows down, should stop immediately hydraulic pamp, seek the unusual reason of the rate of rise and also disposed.After pressure in the pressure testing bottle surpasses nominal operating pressure, the pressure testing bottle is impacted or collide.When manometric indicating value is not reduced to " zero ", forbid to dismantle all pressure parts and dismounting pressure testing bottle 2 on the bearing pipe, forbid to screw the articulation 9 on the bearing pipe.Must make the pressure slow decreasing during release.Test unit should use or special use by the dress medium classification that rushes for the treatment of trial jar generally speaking, in case different media influences each other.If find to prepare before the examination or process of the test in a certain link make mistakes, and may affect the correctness of test findings the time, this invalidate the test then.Test water must be clean fresh water.The temperature of test water must not be lower than 5 degree, is not more than 2 degree with the interior temperature difference of water jacket in the pressure testing bottle 2.Being provided with the indoor tank that the splendid attire test water must be set of test unit, could be used for the hydraulic testing at the indoor water purification that leaves standstill 24h.Treat that trial jar must be the gas cylinder that is up to the standards by related standards except the hydraulic pressure test.
