Embodiment
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-Fig. 3, leakage test device for medical filter, comprise support body 1, the water tank 2 be fixed in support body, the castor 22 that is arranged on the electric cabinet 20 on support body one end and is arranged on bottom support body.Filter dive cylinder 16 is equipped with by dive cylinder mount frame in the corresponding water tank top position place of described support body, and is provided with the shutoff cylinder 23 of the compression cylinder 8 and horizontal motion that can move up and down by shutoff cylinder mount frame.Described dive cylinder mount frame comprises dive cylinder linear axis web joint 3, dive cylinder supports plate 13 and dive cylinder web joint 14, install dive cylinder linear axis 4 and dive cylinder linear bearing 19 respectively at dive cylinder linear axis web joint 3 two ends, described dive cylinder linear axis is fixed through dive cylinder supports plate 13 and dive cylinder web joint 14.The affixed dive riser 17 of described dive cylinder supports plate 13 central bottom and the dive base plate 21 be connected with dive riser 17, dive base plate 21 is provided with filter pedestal for placed 6.Described filter dive cylinder 16 is packed on dive cylinder web joint 14, and its piston rod is connected with dive cylinder supports plate 13 by screw 15.
Described shutoff cylinder mount frame comprises symmetry and is arranged on shutoff Cylinder mount bracket 9 bottom dive cylinder supports plate 13 two ends and shutoff cylinder linear axis mounting bracket 11, and described shutoff cylinder linear axis mounting bracket is equipped with shutoff cylinder linear axis 10 and shutoff cylinder linear bearing 12.Described shutoff cylinder linear axis 10 is connected with shutoff connecting link 7 by shutoff cylinder linear bearing 12, and filter shutoff 5 is equipped with in one of them shutoff connecting link lower end described, and the other end of filter shutoff is by shutoff rubber cushion 25 Bonding pressure relay; Another shutoff connecting link 7 lower end is connected with pressure detection shutoff 18, and pressure detection shutoff 18 one end is by shutoff rubber cushion 25 Bonding pressure sensor.In the present embodiment, adopt two symmetrically arranged shutoff cylinders 23, each shutoff cylinder one end is connected with shutoff Cylinder mount bracket 9, the other end connects shutoff connecting link 7, described compression cylinder 8 upper end is connected with shutoff Cylinder mount bracket 9, compression cylinder 8, for pushing down two interfaces of filter 24 respectively, is connected with two interfaces of filter exactly so that filter shutoff 5 and pressure detection shutoff 18 can be distinguished.The effect compressing cylinder 8 is fixing filter three-pronged connector, causes shutoff not tight, cause error of leaking hunting to prevent from moving during the shutoff of shutoff cylinder.
Described electric cabinet 20 is provided with manual enclosed switch, Manual descending switch, emergency stop switch, manual gas-filled switching tube, manual-automatic switch and automatic start switch, after automatically controlling startup, completes various action by programmed control.
Principle of work of the present invention is: forward manual-automatic switch to automated location, and filter is placed on the dive base plate 21 of leakage testing device by operating personnel, and is placed in above filter pedestal for placed 6 by two of filter interfaces, then gas-charging connection is connected to filter interface.Now, start automatic start switch, two compression cylinders 8 are simultaneously descending and be fixed by two of filter interfaces, then two symmetrically arranged shutoff cylinders 24 are automatically started to direction motion in opposite directions, and the shutoff 18 of the filter shutoff 5 and Bonding pressure sensor that promote Bonding pressure relay runs in opposite directions and two of a filter Interface realization can be sealed, whether filter shutoff 5 detects connector unobstructed, and whether namely shutoff 18 detects connector unobstructed and carry out pressure detection.As shown in Figure 3, the inflation of filter 24 is by inflation inlet air inlet, and admission pressure can set; Filter shutoff 5 left end connects the unobstructed detection that pressure switch carries out three-pronged connector, namely has signal to export if unobstructed, and under the condition that shutoff 18 right-hand member three-pronged connector is also unobstructed, pressure transducer just carries out the pressure detection of filter.Pressure switch is connected on pressure display unit by tracheae, reaches the closed output signal of pressure back contact and judges that trident is unimpeded.
Start hand-pump system, make it reach setting value by gas charging system to filter inflation, pressure switch action proves that trident connector is unimpeded, then automatically starts next program shutoff 18 and detects the unimpeded detection of three-pronged connector and reach set pressure.
The dive cylinder crane DL synchronization that automatic lifting program makes filter dive cylinder 16 and is made up of dive cylinder linear axis 4, dive cylinder supports plate 13, dive riser 17 and dive base plate 21 etc., and make then to carry out leak test detection in filter immersion water tank.After leak test detection reaches setting-up time, filter dive cylinder 16 and dive base plate 21 etc. form crane and synchronously rise, if there is leakage phenomenon in leak test testing process, filter dive cylinder and dive cylinder crane can automatically rise and report to the police.
This device is also provided with autoalarm, and autoalarm is arranged in pressure display unit, realizes fault alarm and detection completes warning by different acoustic.
