Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, a kind of watertightness performance testing inspection of the present invention system, comprising: water supplying unit, its outlet is communicated with testing container 3 by pipeline, and water supplying unit is used for providing pressure stability and the water source of pressure adjustable joint to testing container 3; Flow detection unit, is arranged on the pipeline between described water supplying unit and testing container 3, and flow detection unit is used for the fluctuations in discharge in signal piping, and testing result is fed back; Alarm unit, is connected with flow detection unit, for receiving the signal of flow detection unit feedback, and judges whether to give the alarm.
Concrete, described flow detection unit comprises sensor 4 and is connected to described sensor 4 imports and exports the first valve 7 and the second valve 9 on pipeline, and sensor 4 is for the water volume flow rate in signal piping.And described flow detection unit is parallel with branch road, described branch road is provided with the 3rd valve 8.Before test, need, first to water filling in testing container 3, to close the first valve 7 and the second valve 9, open the 3rd valve 8 on branch road, open the solenoid valve between variable frequency pump 1 and accumulator 2, start water filling; The water of the pressure stability that accumulator 2 flows out directly enters testing container 3 from branch road, until the vent port of testing container 3 there are flowing out, illustrates in testing container 3 and is full of water, shut electromagnetic valve, stops water filling, and closes the vent port of variable frequency pump 1 and testing container 3.In the injecting process, current are without sensor 4, play the object of protection sensor 4, extend its serviceable life.
Described alarm unit comprises the processor 5 be connected with described sensor 4 and the hummer 6 be connected with described processor 5; The information that described processor 5 detects for receiving, processing described sensor 4, and judge whether to send alarm command to hummer 6 according to result; Described hummer 6 is for the alarm command that receives described processor 5 and send and give the alarm.Described processor 5 is connected with display module, for showing the water volume flow rate that described sensor 4 detects.
As shown in Figure 2, after water filling terminates, close the 3rd valve 8, open the first valve 7 and the second valve 9, make current through the probe of sensor 4; According to the pressure values of operating mode free setting primary pressure, final pressurization value, pressure difference, voltage stabling control step by step between pressurization, build the pressure the parameters such as time, open variable frequency pump 1 to pressurize, when the pressure in pipeline reaches setting value, the rotating speed of adjustment variable frequency pump 1, makes manifold pressure keep stable; Then system enters the state of building the pressure, build the pressure certain time, build the pressure in process, the flow velocity of water in the real-time testing pipes of sensor 4, and change the data measured into electric signal and feed back to processor 5, processor 5 pairs of data process, and obtain the flow parameters in pipeline, and are transferred to display module and show; If the flow parameter after process exceedes setting value, illustrate that testing container 3 has leakage, processor 5 sends alarm command signal, and hummer 6 Received signal strength starts to give the alarm.
Do not report to the police in process if build the pressure, illustrate that container does not leak, now continue pressurization, repeat above-mentioned steps, again carry out voltage stabilizing, build the pressure, detect operation, until pressurization value reaches final pressurization value, if No leakage, then measured; If find that there is flow variation in measuring process or report to the police, then testing container 3 is defective.
