Abstract

The invention relates to the technical field of filter detection and particularly relates to a dry-type airtightness detector for an automobile filter. The detector comprises an operation table, a jacking device, a fixed sealing device, an air pump, a pipeline system, a four-way electromagnetic valve, an air tank, a micro-pressure detection device and a controller, wherein the micro-pressure detection device and the jacking device are both arranged on the operation table, the fixed sealing device is connected with a working end of the jacking device, the pipeline system comprises a first communicating pipe, a second communicating pipe, a third communicating pipe, a corrugated communicating pipe and a connecting pipe, one end of each communicating pipe is communicated with a working end ofthe four-way electromagnetic valve, the other end of the first communicating pipe communicates with a gas tank gas outlet, the other end of the corrugated communicating pipe penetrates through the jacking device to be communicated with an air outlet end of the fixed sealing device, and two ends of the connecting pipe are communicated with an air outlet of an air pump and an air inlet of an air tank respectively. The device can recycle detection gas, and working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of filter detection, in particular to a dry-type air tightness detection machine for automobile filters. Background technique [0002] Filters are mainly used in automobiles, air compressors and other equipment to filter air or oil products, etc., and since filters are used for air and oil filtration, they usually have quite high requirements on their airtightness. [0003] The existing filter structure mainly includes a cup body, a filter element is arranged in the cup body, an end cover is arranged at the mouth of the cup, and the end cover and the mouth of the cup are mainly sealed by riveting. When testing, it is mainly to put the whole filter into the water, and then to check whether there are air bubbles in the water by releasing gas into the end cap. The filter is completely dried, and after the water enters the filter, the short-term drying process cannot completely ensure that the water stains in t...
