Embodiment
Fig. 1 is an automobile radiators sealing property testing equipment structure principle chart, and in Fig. 1, the automobile radiators sealing property testing equipment is made up of air switch 1, the time relay 2, oil-water separator 3, solenoid directional control valve 4 and water container 5.
The oil-water separator 3 that the utility model adopted has pressure regulator valve and tensimeter, can adjust pressure as required; The time relay 2 that the utility model adopted is cycle time relay, the a pair of normally opened contact and a pair of normally closed contact of the time relay are interlockings, as being adjusted into S1 and S2 cycling time, when the time relay is worked, the normally closed contact energising S1 of the outage S1(of the normally opened contact elder generation time relay of the time relay), be recycled to the normally closed contact outage S2 of the normally opened contact energising S2(time relay of the time relay then).
In Fig. 1, first outlet of solenoid directional control valve 4 links to each other by the upper port of tracheae with the automobile radiators 6 of need test, second outlet of solenoid directional control valve 4 links to each other with oil-water separator 3 by tracheae, oil-water separator 3 external high-pressure air pipes link to each other with foot of the ground wire with the stitch mutually that air switch 1 connects AC power with the two ends of the power supply bundle of lines time relay 2 solenoids; One end of the time relay 2 normally closed contacts and alternating current line end electrical connection mutually, the other end of the time relay 2 normally closed contacts is electrically connected with an end of solenoid directional control valve 4 solenoids, and the other end of solenoid directional control valve 4 solenoids is electrically connected with the AC power earth terminal.
The normally closed contact of the time relay 2 commutates to solenoid directional control valve 4, and (the solenoid energising of solenoid directional control valve makes the spool in the valve move commutation in control, solenoid outage retracing spring makes spool commutation return), further by the break-make gas control system of solenoid directional control valve 4 realizations to automobile radiators 6;
In the water container 5 water is housed, the heating radiator of being tested 6 lower port that are inserted with tracheae are blocked with plug, put into water container 5 invasion waters, thereby realize automobile radiators is carried out the sealing property test.
Fig. 2 automobile radiators sealing property testing equipment principle wiring schematic diagram, in Fig. 2, the time relay 2 solenoids one end and normally closed contact one end and air switch line end electrical connection mutually; The time relay normally closed contact other end is electrically connected with solenoid directional control valve 4 solenoids one end; The time relay solenoid other end and the solenoid directional control valve 4 solenoid other ends are electrically connected with the air switch earth terminal; First outlet of solenoid directional control valve 4 links to each other by the upper port of tracheae with the automobile radiators 6 of need test, and second outlet of solenoid directional control valve 4 links to each other oil-water separator 3 external high-pressure air pipes with oil-water separator 3 by tracheae.
Its principle of work is:
Requirement according to GB 9421-88 " automobile radiators technical conditions ", the detection method of sealing property is to pour out behind the radiator by injecting full water, draining 5min, then all apertures are blocked, immerse in the normal temperature tank, heating radiator inside passes to the pressurized air that pressure is 1.5 times of compound filler cap air outlet valve opening pressures, and dwell time 30S does not allow any gas leakage.
Before the automobile radiators sealing property is tested, pouring out after heating radiator 6 fills with water that will test, draining 5min, then all apertures are blocked, with tracheae first outlet of solenoid directional control valve 4 is linked to each other with the upper port of heating radiator 6, heating radiator 6 immersed be equipped with in the water container 5 of normal-temperature water, the admission piece of oil-water separator 3 is linked to each other with high-pressure air pipe joint in the test site with tracheae.During test, open the high-pressure air pipe switch, with the pressure regulator valve of oil-water separator 3 air pressure of high-pressure air pipe being transferred to 1.5XMPa(X is the compound filler cap air outlet valve of the heating radiator opening pressure of being tested), air switch 1 attaching plug is inserted in the supply socket of～220 V, can be provided with 30S after being transferred to 30S and 30S(the cycling time of the time relay 2 arbitrarily according to test situation).
Its principle of work is:
1, to the control of heating radiator ventilation pressurize 30S:
2, to the die control of 30S of heating radiator:
The time relay 2 is recycled to retracing springs in the solenoid outage 30S → solenoid directional control valve 4 of back 30S → solenoid directional control valve 4 and makes spool move commutation 30S → spool to move commutation and cut off solenoid directional control valve 4 first outlets and the second venting channels → heating radiator that the exports 30S that dies;
In time, whether have gas leak phenomenon, as do not have if observing the heating radiator 6 that immerses in the water container 5, can turn-off the air switch power supply, cuts off source of the gas, finishes test at heating radiator ventilation pressurize 30S.
As observing continuously, allow the time relay constantly circulate, the every circulation primary of the time relay, time relay normally closed contact closure once, disconnect then once, make heating radiator ventilation pressurize 30S once, heating radiator dies 30S once, on-off-Tong once is a circulation.
