一、前言水力输送是利用水力输送固体材料的一种方式。管道输送,具有建筑费用低,输送能力大,运转可靠,使用方便,施工期限短、能节省大量人力、物力等优点。目前许多国家在冶金、煤炭等方面广泛采用管道水力输送。我国劳动人民在长期水利建设的实践中,创造了利用水力输送泥土修堤筑坝的经验。大量节约了劳力、物力和时间。随着我国社会主义建设的飞跃发展,水力输送已成为我国工农业生产中一个重要方面。近年来,我国在采矿、冶金等部门已较广泛采用水力输送,但在设计方面多用国外的一些计算公式,
I. INTRODUCTION Hydraulic transmission is a way of using water to transport solid materials. The pipeline transportation has the advantages of low construction cost, large transmission capacity, reliable operation, convenient use, short construction period, and saving a lot of manpower and material resources. At present, many countries have adopted extensive pipeline hydraulic transmission in metallurgy and coal. In the long-term water conservancy construction practice, the working people of our country have created experience in using water to transport mud to build dikes and dams. Significant savings in labor, material resources and time. With the rapid development of China’s socialist construction, hydraulic transmission has become an important aspect of China’s industrial and agricultural production. In recent years, China’s mining, metallurgical and other departments have adopted more extensive hydraulic transmission, but in the design of the use of some foreign formulas,
