Emulsion air suction prevention liquid supply device

The utility model relates to an emulsion air suction prevention liquid supply device which comprises an emulsion box and an emulsion pump station, an emulsion suction booster pump is installed at the position of a liquid supply port of the emulsion box, a pressure sensor is installed at an outlet of the emulsion suction booster pump, and when the real-time pressure value alpha 1, monitored by the pressure sensor, of liquid output by the booster pump is smaller than the set pressure value alpha 2, the emulsion pump station is started. And controlling the booster pump to stop running. The liquid suction booster pump is installed at the liquid supply port of the emulsion box, liquid is forcibly supplied to the emulsion pump station, and the problem that the liquid use requirement of the emulsion pump station cannot be met due to the problem of underground geological conditions of a coal mine is solved. 本实用新型涉及一种乳化液防吸空供液装置，包括乳化液箱和乳化液泵站，在乳化液箱的供液口处安装有吸液增压泵，吸液增压泵的出口安装有压力传感器，由压力传感器监测出的增压泵输出液体的实时压力值α1在小于设定压力值α2时，控制增压泵
