The signal test table is established where the Labview signal collection system collects the concrete exit pressure signals, the piston displacement signals of concrete cylinder and the main hydraulic signals. The real measured signals are processed through arithmetic equilibrant filter of the data signal processing method. The pumping efficiency and relative error of real time output are measured by two output calculation methods.

The invention is to control transmission ratio of a continuously variable hydrostatic transmission including an input shaft, an output shaft, a hydraulic pump unit driven by the input shaft, a grounded hydraulic motor unit, and a wedge-shaped swashplate drivingly, pivotally connected to the output shaft and positioned to accommodate pumped hydraulic fluid exchanges between the pump and motor units.

为了控制一可连续地变化的静液传动装置的传动比，该传动装置包括一输入轴（14）、一输出轴（16）、由输入轴（14）驱动的一液压泵装置（18）、被固定的一液压马达装置（20）、和一楔形斜盘（22），其被可驱动地转动连接到输出轴（16）上并且被定位成在泵和马达装置（18，20）之间容纳泵送的液压流体交换。

Performance prediction of the pump when transporting water and salt solution is also studied.Results are compared and analyzed with experimental data.6.The salt-out flow field is measured on three dimensions by Particle Image Velocimemter via radial and axial two test models.After image processing, velocity distribution of crystal particles in the pump is obtained.Particle flow field is visualized to reveal the particle motion law intuitionally.

此外对泵送清水和盐溶液时的性能也进行了预测，并将结果与外特性试验数据对比。6、运用PIV在径向和轴向两种测量模式下对泵内不同外部条件下盐析两相流场进行了准三维测量，经图像后处理，获得了盐析晶体颗粒在叶轮内、无叶腔中及轴面上的速度矢量分布，实现了颗粒流场的可视化，更为直观地揭示了泵内盐析颗粒的运动规律。

Should not be filled with concrete hopper online, on-line super-size aggregate and debris to be cleared in time, when the mixing hopper card axis was never transferred, it is necessary to suspend the pump, and a timely reversal operation, troubleshooting , hopper of the concrete should not be too few to prevent air suction pipe and plug the cause, when the feed can not keep up, it is necessary to stop pumping in time.

、料斗网上不应堆满混凝土，对网上的超粒径骨料及杂物要及时清除，当料斗内的搅拌轴被卡死不转时，要暂停泵送，并及时反转操作，排除故障，料斗中的混凝土不能太少，以防止因吸空而导致管路堵塞，当供料跟不上时，要及时停止泵送。
