FIELD: physics. ^ SUBSTANCE: in the device, a removable sealer is docked to the magnetic fluid sealer, where the removable sealer is fitted with a pressure measuring device and a drainage valve. The inner volume of the pressure measuring device, drainage valve and the closed cavity formed by the magnetic fluid sealer under test, the removal sealer and the shaft are limited to the maximum. Smoothly rising pressure is formed at the input of the magnetic fluid sealing system and the time at which pressure begins to rise in the closed cavity is recorded at the output, and the pressure difference determines the maximum holding capacity of the magnetic fluid sealing system. ^ EFFECT: possibility of determining holding capacity of magnetic fluid sealing systems for any diametre of shafts, including large diametres. ^ 1 dwg, 2 cl |
