Abstract

The utility model discloses an exhaust manifold leakage test device, which comprises a test frame body, a pneumatic pressing device, a sealing ring and an air tightness leakage detection instrument, wherein the pneumatic pressing device is arranged on the test frame body, the sealing ring is arranged on an air inlet of a tested product, and the air tightness leakage detection instrument is connected with the tested product through an air duct. The utility model changes a sealing pad into the sealing ring, so the air leakage defective rate of the small air holes or collision and scratch on large surfaces of the product is lowered from the original 0.8 percent to 0, the equipment is changed from a water soaking type leakage detection instrument into the air tightness leakage detection instrument, the leakage quantity is controlled to a level lower than 11 Pa under the conditions of the set leakage test pressure of 207 kPa and the leakage test time of 88 seconds, simultaneously, the equipment realizes the automatic warning effect, a manual pressing device is changed into the pneumatic pressing device, the product installing and clamping stability is enhanced, and finally, the utility model ensures that the problem that the gas leakage of the exhaust manifold can not be accurately judged is solved.

Description

A kind of exhaust manifold leakage testing device
Technical field
The utility model belongs to exhaust manifold detection technique field, particularly a kind of exhaust manifold leakage testing device.
Background technology
At present, internal combustion engine just develops towards direction high-power, light weight, and its reinforcing degree improves constantly.The thermal load of reinforcing stimulus is one of key issue in its development process.Exhaust manifold is the part that mainly is heated of engine, it directly contacts with high-temperature fuel gas, and temperature is higher, and working environment is very abominable, particularly the effect repeatedly owing to high temperature and the even thermal stress that produces of temperature distributing disproportionation often forms heat fatigue cracking, causes its destruction.The impermeability that guarantees exhaust manifold is a difficult point in the production run often, and the testing staff typically uses the sealed silicon rubber cushion and contacts with product when detecting, but the silicagel pad area is big, and the scuffing of colliding with little on the product can not detect; By gas outlet is immersed in the water, to leak test equipment and each pipeline inflation of gas outlet, whether there is bubble to produce by operative employee's range estimation, judge whether product leaks gas, because of little bubble is difficult for discovering, easy detection is not come out during leak test, causes the inaccurate of testing result.Equipment can not be reported to the police automatically in addition, no time monitoring.
The utility model content
The utility model provides a kind of exhaust manifold leakage testing device that can judge accurately whether exhaust manifold leaks gas.
A kind of exhaust manifold leakage testing device, it comprises test support body, air clamper, O-ring seal and airtight leak locator, described air clamper is arranged on the test support body, and O-ring seal is arranged on the air intake opening of test product, and airtight leak locator is connected by wireway with test product.
Described airtight leak locator is provided with warning device.
The utility model changes sealing gasket into O-ring seal, directly cause big little pore of product or collide with scratching the gas leakage fraction defective and being reduced to 0 by former 0.8%, and change equipment into airtight leak locator by the immersion type leak locator, can be at the leak test pressure 207KPa that sets, under 88 seconds leak test time, the control leakage rate is less than 11Pa, equipment has been realized automatic warning again simultaneously, manual hold down gag is changed to air clamper, strengthen product clamping stability, finally guaranteed accurate exhaust manifold this difficult problem of whether leaking gas of judging.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of exhaust manifold leakage testing device, it comprises test support body 1, air clamper 2, O-ring seal 3 and airtight leak locator 5, described air clamper 2 is arranged on the test support body 1, O-ring seal 3 is arranged on the air intake opening of test product 4, and airtight leak locator 5 is connected by wireway 6 with test product 4.
Described airtight leak locator 5 is provided with warning device.
The utility model changes sealing gasket into O-ring seal, directly cause big little pore of product or collide with scratching the gas leakage fraction defective and being reduced to 0 by former 0.8%, and change equipment into airtight leak locator by the immersion type leak locator, can be at the leak test pressure 207KPa that sets, under 88 seconds leak test time, the control leakage rate is less than 11Pa, equipment has been realized automatic warning again simultaneously, manual hold down gag is changed to air clamper, strengthen product clamping stability, finally guaranteed accurate exhaust manifold this difficult problem of whether leaking gas of judging.
