Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile fuel, an airtight inspecting unit for an oil supply pipe unit,

The present invention relates to an automobile fuel supply system and an oil supply system, and more particularly, to an automobile fuel supply system and an oil supply system, , A tightness inspection of a pipe unit for supplying oil and a cleaner.

As is known, an automobile has a fuel supply pipe unit for supplying fuel to the engine and an oil supply pipe unit for supplying oil.

In order to prevent the pipe unit from colliding with peripheral parts installed in the engine room, the pipe unit is formed to have a fixed piece so that it can be installed at a predetermined position while being bent in various forms. And ring-shaped connectors are integrally formed on both sides of the pipe unit.

After manufacturing the automobile fuel and oil supply pipe unit constructed as described above through various processes, it is possible to prevent leakage phenomena due to welding failure in each part of the pipe unit, which may be damaged in the manufacturing process, And to perform the airtight inspection for providing a pipe unit with excellent quality and to remove the foreign substance generated in the manufacturing process.

The airtightness inspection and the cleaning operation of the fuel unit and the oil supply pipe unit described above will be described in detail. First, the airtightness inspection of the pipe unit is performed mechanically to check whether the air is poured by injecting air into the pipe unit. There is a disadvantage in that the efficiency is largely deteriorated because it is not injected at a high pressure.

In addition, since the foreign substance cleaning is performed manually by the inside of the pipe unit, it is not possible to perfectly remove the foreign matter, and the cleaning liquid used for cleaning can not be completely removed, and the inside of the pipe unit is air- Or drying by applying heat. In such a case, since the removal and drying of foreign substances in the pipe unit are not performed completely, there are many problems such as deterioration of quality and defects by providing cause of oxidation.

Particularly, since the pipe unit for fuel and oil supply is attached to the airtightness tester of the pipe unit, the pipe unit is separated, and the process of manually immersing the pipe unit in the cleaning solution and washing the surface by washing is repeated. There is a problem that it takes a lot of time.

In order to solve the problem of manual hand washing of the pipe unit, a washing operation using an ultrasonic washing machine has been performed. However, even in such a case, a pipe unit for fuel and oil supply is mounted on the pipe unit air- This is also troublesome because it is separated and washed again by immersing it in an ultrasonic washing machine, and since the ultrasonic vibration is not smoothly performed in the inside of the pipe unit, foreign matter can not be completely removed and quality can not be guaranteed there is a problem.

In order to remove the cleaning liquid inside the pipe unit, air is blown into the pipe unit to dry it. However, the pipe unit is held in one hand and the air gun is held in the other hand. When drying is carried out by dropping and applying heat, there is a problem that foreign substances are also dried to form a scale.

The cleaning of the pipe unit as described above has a problem that the work efficiency is greatly reduced because the piping unit is moved after the pipe unit is inspected for airtightness and the work is performed by a separate cleaning and drying apparatus.
