Press out the liquid at this time to overcome the pressure out of pipeline systems with all the necessary resistance to the pressure from the pumpdischarge.
压出，此时液体带有克服压出管道系统所有阻力所必需的压力从泵中排出。

In order to reduce the fluctuation of pressure and discharge capacity of the triplex drilling pump, the air accumulator is often fixed on the discharge pipe.
为了降低三缸单作用钻井泵的压力和排量波动，通常在排出管线上安装有空气包。

TUPWR algorithm was adopted for the pump turbine model, SFPUMP for feed pump system, SOVLV for minimal flow valve, and pressure node for calculating the discharge rate of the pump.
