Technical Field

[0001] The utility model belongs to the technical field of filter detection, and particularly relates to a filter sealing detection device. Background Technique

[0002] Filters are filtering devices that play a crucial role in many fields. They are mainly used to remove impurities, pollutants, and particulate matter in fluids (such as gases, liquids) to protect the normal operation of equipment and improve work efficiency. There are many types of filters, such as air filters, oil filters, fuel filters, hydraulic filters, etc. Air filters are mainly used to filter dust, pollen, particulate matter, etc. in the air entering the engine or other equipment to prevent these impurities from causing wear and damage to the inside of the engine. Oil filters can remove metal debris, gum, carbon deposits, etc. in the oil to ensure the cleanliness of the oil, provide good lubrication and protection for the engine. Fuel filters are responsible for filtering impurities and moisture in the fuel to ensure the purity of the fuel, make the combustion more complete, improve fuel economy and reduce exhaust emissions. Hydraulic filters are used in hydraulic systems to filter pollutants in the hydraulic oil to ensure the normal operation of hydraulic components and the stability of the system.

[0003] The problem of the existing technology is that when the traditional immersion method is used to detect the sealing performance of the filter, only a variety of simple tools are used in cooperation for detection. This method has low detection efficiency, and it is very difficult to carry out the detection without one of the tools. Therefore, we propose a filter sealing detection device.
