摘要
基于水锤发生时伴随有巨大能量的现象,介绍了一种由水泵提供低压水作为驱动源,利用水锤能量的新型脉动水锤发生装置。阐述了该装置的结构组成以及工作原理。采用PCI数据采集卡配合压力传感器构成的数据采集试验系统测定了装置产生的最大峰值压力,并根据采集的数据拟合出峰值压力3个周期的变化曲线。试验结果表明在供水泵4MPa压力水的驱动下,水锤激发的峰值压力最高可达15MPa,脉动水锤的周期约为3.77s;试验中还发现通过改变进入装置的4MPa压力水流量可以调节脉动水锤的周期,流量越小,脉动水锤的周期越大。最后对该装置在煤层注水和电厂有压管道防垢和除垢方面的应用前景进行了展望。
Based on the tremendous energy phenomenon with the reaction of the water hammer, the paper introduced the new pulse water hammer reactor with a water pump providing low pressurized water as the driving power and with water hammer energy. The stated the structure composition and the working principle of the device. The data collection and test system consisted with PCI data collection card and the pressure sensor measured the max peak value pressure of the device. With the collected data, the varied curves of the three periods for the peak value pressures were simulated. The test results showed that under the driving of the water pump 4 MPa pressurized water, the max peak value created from the water hammer could be 15 MPa and the period of the pulse water hammer would be about 3.77 s. During the test, it was found that with the adjustment of the 4 MPa pressurized water flow to the device, the period of the pulse water hammer could be adjusted. With the less of the flow, the period of the pulse hammer would be longer. In the end, the paper had a outlook on the application for the device to the pressurized pipeline antiscaling and descaling for the seam water injection and power plant.
