①扬程是指抽沙泵在单位重量的液体通过泵后所获得能量。其值等于泵的吐出口总水头与吸入口总水头的数量。以符号H表示，单位为米液柱（m）。
H=Hd-Hs
式中：Hd=吐出口总水头（m） Hs=吸入口总水头（m）
HS=Z1-HfL1-Hi1
式中：HfL1=吸入口管段沿程水头损失（m） Hi1=吸入口管段总局部水头损失（m）Z1=吸入口液面高度 （m）Hd=Z2+HfL1+Hi2+ HV
式中：Z2=吐出口管段沿程水头损失（m） HfL2=吐出口管段总局部水头损失（i2=吐出口液面高度(m) V=吐出口水头扩散损失
式中：V2=管路平均流速（m/s） D=管路内径（m） g=重力加速度 f=阻力系数 L=管路当量长度（包括弯头和阀门损失当量）
F值可由公式计算得出，其中K为绝对粗糙度（mm）,Re为雷诺数（纯数值）。

① lift means after pumping sand pump unit weight of liquid through the pump for energy. Its value is equal to the total number of the pump head discharge port and the suction port of the total head. Symbol H represented in meters liquid column (m).
H = Hd-Hs
Where: Hd = spout total head (m) Hs = the inlet total head (m)
HS = Z1-HfL1-Hi1
Where: HfL1 = section along the inlet pipe head loss (m) Hi1 = Administration of the Ministry of the inlet pipe head loss (m) Z1 = suction port surface height (m) Hd = Z2 + HfL1 + Hi2 + HV
Where: Z2 = discharge outlet pipe sections along the head loss (m) HfL2 = discharge outlet pipe section Administration section head loss (i2 = spout surface height (m) V = spit saliva diffusion head loss
Where: V2 = average line velocity (m / s) D = pipe inside diameter (m) g = gravitational acceleration resistance coefficient f = L = line equivalent length (including elbows and valves loss eq)
F value calculated by the formula, wherein K is an absolute roughness (mm), Re is the Reynolds number (pure numeric).
