1.用途特点:泥沙粒徑分析用,可以木經烘称手續直接計算,繪出泥沙分析曲綫,并設备簡单,为泥沙分析工作下放到测站創造了条件。2.原理結构:利用連通管原理,主管內加沙后密度增大,压管水面上升,待主管內泥沙逐漸沉降,密度漸减,压管水面亦逐漸下降。結构系一主管及旁接 1. Uses and Features: It can be used for the analysis of sediment particle size. It can be directly calculated by wood drying procedure and draw the curve of sediment analysis. The equipment is simple and creates the conditions for the sediment analysis to be sent to the station. 2. Principle Structure: By using the principle of connecting pipe, the density of the pipe increases after the charge of Gaza and the water pressure in the pipe increases. When the sediment in the pipe is gradually subsided, the density decreases and the water pressure in the pipe decreases. Structure of a supervisor and bypass
