Abstract
A self-priming apparatus for quick no-water startup includes a front-stage inlet chamber, a middle-stage gas-liquid separation chamber, and a rear-stage gas-liquid separation chamber. A plurality of two-stage chamber gas-liquid separation one-way channels are symmetrically arranged between adjacent chambers of the front-stage inlet chamber, the middle-stage gas-liquid separation chamber and the rear-stage gas-liquid separation chamber. A plurality of one-way outlets are symmetrically arranged in an inner cavity of the rear-stage gas-liquid separation chamber. By decreasing or increasing the volumes of an outer cavity and an inner cavity of the front-stage inlet chamber, water is sucked in due to pressure difference and water intake and preliminary gas-liquid separation are carried out. The middle-stage gas-liquid separation chamber is configured for gas-liquid separation. By decreasing or increasing the volume of the inner cavity of the rear-stage gas-liquid separation chamber, water is rapidly expelled due to pressure difference and gas-liquid separation is carried out.
