Equations based on hydrodynamics, thermodynamics, gasdynamics and the law of energy conservation are used to find the time required for self-priming and rate of air pumping.
根据流体力学、热力学、气体动力学方程和能量不变方程，求得了自吸时间和抽气速率公式。
Have good self-priming, and so every time there is no need to open before the pump filled with liquid.
具有良好的自吸性，故每次开泵前无须灌入液体。
