Hose 5 is connect with connector 6, and the mobile device includes worm screw 16, worm gear 17, screw rod 18, bearing block 19, nut 20 and leads
Bar 23, the worm screw 16 are connect with the output shaft of motor 15 by shaft coupling, and worm screw 16 is meshed with worm gear 17, worm gear 17
It is fixedly connected with nut 20, nut 20 is connected through a screw thread with screw rod 18, and screw rod 18 is connect with baffle 21 by bearing, described
Nut 20 is rotatably connected with bearing block 19, and bearing block 19 is connect with 12 inner top wall of air storage chamber, the quantity of the guide rod 23
It is two, two guide rods 23 are located at the side of screw rod 18, and two guide rods 23 are across respectively inside air storage chamber 12, and two are led
Bar 23 is slidably connected with baffle 21 respectively.
Pressure sensor B24 is equipped with inside the air storage chamber 12 and pressure sensor is fixed in fixed plate 13.
The air storage chamber 12 is equipped with solenoid valve 2.
The gauge outfit 3 is equipped with control panel 7, and control panel 7 is equipped with display screen 8 and key screen 9.
Specific implementation process is as follows: in use, controller is equipped on control panel 7, controller is NFC control
Device, controller are connect with display screen 8 by conducting wire, and controller is connect with key screen 9 by conducting wire, and controller passes through with air pump 11
Conducting wire connection, controller are connect with motor 15 by conducting wire, and controller is connect with solenoid valve 2 by conducting wire, controller and pressure
Force snesor A10 is connected by conducting wire, and controller connect with pressure sensor B24 by conducting wire, and when calibration, connector 6 is pacified
On Devices to test, air pump 11 is controlled by key screen 9 and is powered, the gas that air pump 11 generates enters air storage chamber 12 by pipeline
Inside, the pressure being fixed on inside the pressure sensor B24 measurement air storage chamber 12 in fixed plate 13, meanwhile, it is controlled by key screen 9
