Problems solved by technology

However, the former has the risk of radiation injury and requires higher professional quality of operators; the latter is affected by the fixed position and number of sealing devices, and a single device can generally only test the airtightness of exhaust manifolds of a series of cylinders. The flexibility is poor, and the specific leakage point cannot be accurately judged, which affects the use effect

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.

Abstract

The invention provides novel equipment capable of detecting exhaust manifold airtightness and an application method. The novel equipment comprises a detection vehicle, a starter, an alarm device and awater-gas three-way main pipe, wherein a plurality of vertical and transverse slideways are arranged on three sides of the detection vehicle, a plurality of clamping devices and a sealing device witha first claw stretch out from the inner portion of the vertical and transverse slideways, the clamping devices and the sealing device are respectively connected with a power device, a tail end of thepower device penetrates through the vertical and transverse slideways, the power device moves on the vertical and transverse slideways, the detection vehicle is provided with automatic water injection pipe fittings and automatic air transmission pipe fittings, the starter and the alarm device are arranged outside the detection vehicle and are connected with a control system through sensors, the water-gas three-way main pipe is provided with an exhaust manifold connection device and is further provided with two branch pipes, and the branch pipes are respectively connected with the automatic water injection pipe fittings and the automatic air transmission pipe fittings. The novel equipment is advantaged in that manifold airtightness is detected through compression water seepage, the detection effect is visual and obvious, and one machine multiple purposes is realized.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and relates to a device capable of detecting the airtightness of an exhaust manifold and a use method. Background technique [0002] The exhaust manifold is connected to the cylinder block of the automobile engine, and the exhaust gas discharged from each cylinder is collected and introduced into the exhaust main pipe, with a conduit with branch lines. At present, the common practice of various engine manufacturers is to package the three-way catalytic converter used to purify the exhaust gas in the exhaust manifold. If the airtightness of the exhaust manifold is not good, the exhaust gas will not only pollute the car body, but also reduce the exhaust gas of the vehicle. System life, more seriously, will cause pollution to the atmospheric environment. After the finished exhaust manifold is completed, it needs to pass the air tightness test. In the existing technology, the exhaust manifold can...
