Embodiment 1
[0033]A device that can detect the airtightness of exhaust manifolds, including a detection car 1, a starter and an alarm 2, and a water-air tee 21; The slideway 11 extends inwards a plurality of clamping devices 5 and a sealing device 7 with claws 16; the clamping devices 5 and sealing devices 7 are respectively connected to the power unit, and the tail of the power unit runs through the vertical and horizontal slideways 11 , moving on the vertical and horizontal slideway 11; the detection car 1 is provided with an automatic water injection pipe 8 and an automatic gas delivery pipe 3; the starter and the alarm 2 are arranged on the outside of the detection car, and are connected to the control system through sensors; The main pipe of the water-air tee 21 is provided with an exhaust manifold connecting device and two branch pipes 27; the branch pipes 27 are respectively connected to the automatic water injection pipe 8 and the automatic gas delivery pipe 3. The power unit incl...
Embodiment 2
[0037] The second embodiment is basically the same in structure and principle as the first embodiment, except that the clamping device 5 and the support base 10 are provided with electromagnetic coils inside. After placing the branch port of the exhaust manifold to be tested upright on the support base 10, the clamping device 5 and the electromagnetic coil inside the support base 10 are energized to form an electromagnet, which attracts the exhaust manifold to initially fix the exhaust manifold to be tested. exhaust manifold.
Embodiment 3
[0039] The third embodiment is basically the same in structure and principle as the first embodiment, except that the automatic gas delivery pipe 3 is provided with a high-power heating wire 19 and a pressure relief valve 20 inside. After completing the leak detection, open the pressure relief valve to release the pressure 20, discharge the water in the exhaust manifold, start the high-power heating wire 19, blow hot air into the exhaust manifold, and dry the residual moisture.
