在油田注水泵性能的测试计算中,需要应用等熵温升值△Ts。根据等熵温升曲线图的泵出口压力和入口温度,找出△Ts值,然后代入公式计算。这种方法工效低,且易出错。经进一步研究,我们对等熵温升曲线建立数学模型,可以计算曲线簇范围内任意点的△Ts值,使油田注水泵性能测试人员不必查图纸,只须将有关的测试参数输入计算机,计算机就能立即打印出计算结果,包括泵效等十个参数,提高工效二十倍以上。该程序稍加改动,即可在其它型号的计算机上使用。
In the field of water injection pump performance test calculation, the need to apply the isentropic temperature rise △ Ts. According to the isentropic temperature rise pump outlet pressure and inlet temperature, find △ Ts value, and then substituted into the formula. This method is inefficient and error-prone. After further research, we set up a mathematical model of isentropic temperature rise curve, which can calculate △ Ts value of any point within the curve cluster, so that oilfield water pump performance test personnel do not have to check drawings, only the relevant test parameters into the computer, computer You can immediately print out the calculation results, including pump efficiency and other 10 parameters to improve work efficiency twenty times more. The program a little change, you can use on other types of computers.
