基于流量的水泵运行数据采集系统摘要摘要：水泵技术是一个半理论和半经验的实验学科。在水泵的开发中已经进行了实验研究。脚的地位和作用。作者指的是大量国内外相关文献，主要关注泵流量，提出了磁头，轴功率和速度的测试原理和测试方法，并将电测量方法与电机效应相结合。速率特性曲线测量泵轴功率，从而避免损耗分析方法中的大量复杂中间过程，满足测试设备的自动测量要求;使用漏磁感应线圈法测量电机的速度来弥补其他水下电机测试速度测量方法的局限性已经适用于 Ryan 公司开发的潜水泵。实际需要。在此基础上，作者设计了一种基于单片机系统的外围测量方法。该电路实现了各种传感器输出信号的实时准确数据采集。此外,作者还对水泵测试系统的精度作了分析,对测量系统误差的主要来对源进行了探索，得出了用于选择测试仪器精度的数学模型。在处理测量数据时，采用中值滤波和二次曲线拟合技术，尽可能确保软件测量值的准确性。关键词：水泵；数据采集；流量Abstract:Water pump technology is a semi-theoretical and semi-empirical experimental subject. Experimental research is of great significance in the development of water pumps. A pivotal position and role. The author, referring to a large number of relevant domestic and foreign documents, emphatically discusses the pump flow rate,The testing principle and method of lift, shaft power and rotating speed are proposed, and the electric measuring method is combined with motor efficiency.The rate characteristic curve measures the shaft power of the water pump, thus avoiding a large number of complicated intermediate processes in the loss analysis method.The automatic measurement requirements of the test device are met. The magnetic flux leakage induction coil method is adopted to measure the rotating speed of the motor to compensateThe limitation of other rotational speed measurement methods to underwater motor testing is overcome, which is suitable for the development of submersible electric pump by Laing Company. The actual needs of th...
