Description
Technical Field
The invention relates to the field of performance detection of an air inlet purification product of an engine, in particular to a tool and a method for detecting air tightness of a spiral-flow tube type air filter.
Background
The cyclone tube type air filter is an important part in a vehicle engine, the efficiency of the cyclone tube type air filter is determined by the efficiency of a cyclone tube element, and the cyclone tube is developed towards miniaturization along with continuous promotion of the requirement on the efficiency of the cyclone tube at present. Especially, some swirl tubes of the air filter of special vehicles have tube diameters even smaller than 10mm, and the result is that dozens or even hundreds of swirl tubes are used by one filter.
As shown in fig. 1-3, the cyclone tube air cleaner axially admits air and discharges air, separates dust into a dust collecting chamber, and discharges the dust in the dust collecting chamber through a dust suction device (such as a dust suction pump). For the cyclone tube type air filter, the effect of ensuring dust extraction is a key factor for maintaining high efficiency air filtration, so the air tightness in the dust collection cavity is most important.
If the cyclone tube that cyclone tube air strained can not form confined space after the installation is accomplished, then leak gas slightly will reduce cyclone tube air cleaner's efficiency by a wide margin, thereby make a large amount of dusts pass through cyclone tube air and strain the entering second grade filter core, finally make the air filter core of cyclone tube rear end block up with unusual speed, need frequent maintenance, increase the maintenance work load to cyclone tube air cleaner, influence the normal use of vehicle, cause bad public praise influence simultaneously.
The spiral-flow tube type air filter shell is a welding part, the air tightness of the welding part is easy to guarantee, and the installation connection part of the spiral-flow tube and the shell leaks air most easily in actual production. However, in actual production, whether the swirl tube is installed or not and whether the swirl tube leaks air or not are often determined by checking whether the swirl tube is loosened or not and the edges of the swirl tube are transparent. These inspections often do not serve to meet the actual use requirements for the installation process level of the cyclone. According to the actual conditions and the inspection requirements, aiming at the cyclone tube type air filter, an air tightness inspection tool and an inspection method are necessary to be developed, so that a manufacturer is required to inspect the air tightness of the cyclone tube installation before the product leaves a factory, and the requirement of a user on product re-inspection is met.
