Device for testing sealing property of grease

The utility model discloses a device for testing the sealing property of grease, and the device comprises a housing. An accommodation cavity which contains water is formed inside the housing. The upper end of the housing is provided with a water inlet. The bottom of the housing is provided with a water outlet hole which is equipped with a filter screen. The filter screen is coated with tested grease which forms a grease film on the filter screen for preventing water in the housing from releasing. When the intensity of the pressure of the water in the housing increases, the grease film is broken by the water in the housing, and then the water releases through the filter screen. The housing is also provided with a pressure gauge which is used for measuring the intensity of the pressure during the releasing of the water. The device provided by the utility model is simple in structure, and is convenient to manufacture and use. Through the comparison of the data of the pressure gauge with the filtering density of
