Abstract
A test method for testing the anti-collapsing performance of a filter element, including four steps of installation, preparation before pressurization, pressurization test and data processing. Uniform external pressure load, the deformation of the filter element is measured by the dial gauge, and finally the external pressure crushing strength of the filter element is obtained. The test method of the present invention is reasonable, easy to operate, obtains the relation between the deformation amount of filter element and the external pressure through the test, and according to the relationship between the deformation amount of filter element and the external pressure pressure, the use condition and environment of the automatic backwashing filter Set certain requirements, or add a device to prevent excessive external pressure in the automatic backwash filter, or improve the structure or material of the filter element to obtain greater compressive strength, so as to avoid the filter element being crushed during use and causing automatic backwashing. The backwash filter is malfunctioning.
Description
Technical field [0001] The present invention relates to a test method for testing filtering anti-external pressure compact properties used in the field of water treatment. Background technique [0002] At present, automatic anti-rinsing filters have been widely used in power plants, ocean, petrochemical and other industries. The automatic anti-rinsing filter is mainly composed of the filter element, the contracted member, the transmission member, and the filter element belongs to the important components of the filter, and its performance is good or bad directly affects the ability of the filter. [0003] The inlet of the automatic anti-rinsing filter is directly connected to the imported water valve. The other end of the imported water valve is connected to the water port pump, and the water port is directly connected to the outlet valve, and most of the imported water valve and the outlet water valve are electrically used in the electricity. Valve or pneumatic valve. When the f...
