| 摘 要： | 针对农业排灌机械的要求和特点，提出并分析了一种可广泛应用于农业生产的压力输送泵——活齿齿轮转子泵的结构形式及工作原理，分析了径向间隙自动补偿的实现方式，推导出了平均流量和瞬时流量公式，研究了该泵的流量特性。结果表明该泵具有流量大、流量脉动小、工作轮齿间无啮合力、运行平稳、噪声低、机械效率高及径向间隙可以自动补偿等诸多优点。在一定条件下，该泵可作为高扬程大流量农用水泵或两相流的压力输送泵，具有广阔的应用前景。

| Abstract: | Aiming at the problems of drainage and irrigation machinery in China, the structure and the working principle of the rotator pump which can be widely used in agriculture were given. The instantaneous flow characteristics and the instantaneous flow pulsation of the pump were analyzed. The flow pulsation rate of the pump was far smaller than that of common gear pump. The engaging power of the pump was zero. The results that the new kind of pump has bigger displacement and higher pressure are obtained and on some conditions it can be widely used in agricultural products processing in China. The research results will be application to the design of the new type of water pump. |
