Described inflation platform is connected with the fixed rack of test board by screw rod.Can adjust the lift rod stroke of cylinder, so that adapt to the filter cleaner of Multiple Type, only need to adjust the height of screw rod, both can adjust easily the working depth of depression bar.Be convenient to test, be convenient to change.
Described cylinder arranges control handle, and control handle is fixed on test board one side.Operate push rod by control handle and compress filter cleaner and air inlet, convenient control.
Described jacking cylinder arranges foot-operated gauge tap, and foot-operated gauge tap is arranged on the ground of frame bottom.Convenient operation: when the workman operated, action is installed, changed to both hands at upper operating, then then the action that compresses and pressurize can step on the jacking of completing water tank by the football star, moves single, avoid bimanualness too much to move and cause error, improve detection efficiency.
The push rod of described cylinder arranges depression bar by fixed head, and the another side of fixed head arranges guide pole, and the pilot hole on guide pole and fixed rack adapts.Guide pole is guaranteed the stroke of push rod, so that guarantee that depression bar compresses filter base exactly.
The beneficial effects of the utility model are: by frame lower, water tank is set, upper rack arranges test board and cylinder, cylinder is fixed on fixed rack, the push rod of cylinder is fixedly installed depression bar, depression bar is arranged on above inflation platform, depression bar and filter base adapt, during testing, the sample corresponding site is stuck on register pin, depression bar compresses filter base under the effect of cylinder, make it to coordinate with sealing gasket airtight, then aerostatic press provides the filling channel of test air by inflation platform to enter filter cleaner; As in water tank, whether range estimation has bubble to emerge, and by overall improvement optimization, makes to have with the filter cleaner after pressurization: 1, detect air pressure high, improve outgoing; 2, change test filter cleaner sample conveniently, improve detection efficiency; 3, easy to operate, save artificial.
