Embodiment 1

[0034] like figure 1 As shown, the gas detection machine for exhaust manifold of the present invention includes a detection platform 1 for placing the exhaust manifold. The detection platform is provided with a pressing device for pressing the exhaust manifold A, and the pressing device includes Lifting rod, the lifting rod is controlled by the cylinder block 4 to move up and down, and the lower part of the lifting rod is also equipped with a plurality of pressure rods 3 for pressing the exhaust manifold. The upper position is provided with an inflatable valve 7 that can slide in the detection platform 1, and the inflatable valve 7 controls its intake air volume and time through a control computer 10 and a control display panel. The control display panel includes a display screen 8 and a control key 9. In the display screen, There are pressure detection display parts, pressure drop range display parts, and ventilation time detection parts. The above-mentioned display parts can...

Embodiment 2

[0044] The difference from Embodiment 1 is that in this embodiment, the inflation time of the inflation valve 7 is set to 10S, the pre-variable pressure of the elastic seal 7.1 in the inflation valve 7 is 12N, and the preset inflation pressure value is 215 KPa. If the change value of the exhaust pipe pressure is less than 1.50 KPa, if it is greater than 1.50 KPa, an alarm will be displayed.

[0045] The rest of the working principles are the same as in Embodiment 1.

Abstract

The invention discloses an exhaust manifold gas detection machine and a detection method thereof. The exhaust manifold gas detection machine comprises a detection platform for placing an exhaust manifold; a compression device for compressing the exhaust manifold is arranged on the detection platform; the exhaust manifold gas detection machine is characterized in that an inflating valve capable of sliding in the detection platform is arranged at the side part of the detection platform; the inflating volume and time of the inflating valve are controlled by a control computer and a control display panel; the inflating valve is also provided with pressure sensor equipment capable of feeding gas pressure data back to a control display device. The detection method is reliable, and the anti-leakage property is improved by more than 40% compared with that of the existing product.

Description

technical field [0001] The invention relates to an exhaust manifold airtight detection device, in particular to an exhaust manifold gas detection machine and a detection method thereof. Background technique [0002] The exhaust manifold is connected to the cylinder block of the engine, and the exhaust of each cylinder is collected and introduced into the exhaust manifold, with divergent pipelines. The casting process generally uses commonly used metal materials. According to the needs of different models, after welding, drilling, calibration and other processes, a multi-tubular mechanism with multiple air inlets and a single air outlet is formed. [0003] However, in the exhaust manifold welding process, due to various welding, human or machine operations are not in place, after the exhaust manifold is welded, it is easy to produce some small leaks, and the existence of these leaks will be extremely serious. It greatly affects the quality of the exhaust manifold, which make...
