为保证卷盘喷灌机水涡轮性能测试数据的真实可靠，需要对卷盘喷灌机水涡轮性能测试系统进行数据校正。为此，通过建立卷盘喷灌机水涡轮性能参数采集数据的数学模型，推导出水涡轮参数采集数据与实际数据的函数关系，得到参数测量误差与实际信号的对应关系；在保证性能测试系统试验条件与试验环境相对稳定的条件下，计算出各性能参数的校正参数，并基于LabView 开发平台对卷盘喷灌机水涡轮性能测试系统数据校正进行软件设计。通过误差分析表明：本研究对卷盘喷灌机水涡轮性能测试系统的数据校正符合 GB／T3216－2005《回转动力泵水力性能验收试验1级和2级》的规定，可以有效提高卷盘喷灌机水涡轮性能测试系统测试数据的准确性。
