介绍了一种适于与气体自动观测仪器配套、应用于地震地下水前兆数字化观测的定量自动脱气装置。该装置根据气体溶解平衡原理设计而成,采用了交联双循环技术,由单板机实现程序控制,可利用连续流经该装置的被测水样,周期性制备定量体积的与被测水样具有确定浓度关系的气态样品,供气体自动观测仪器进一步测量,并按照给定的理论公式,对被测水样中相关溶解气的真实浓度给出精确的定量表达。专门设置的“稳压功能”和“除水功能”使该装置具有较稳定的工作性能。
A quantitative automatic degassing device suitable for digital observation of earthquake groundwater precursors is introduced. The device is designed according to the principle of gas dissolving and balancing. It adopts the cross-linking double-cycle technology and is controlled by the single-board machine. The water sample to be measured that flows continuously through the device can be used to periodically prepare the quantitative volume A gas sample with a defined concentration relationship can be further measured by a gas automatic observation instrument and given an accurate quantitative expression of the true concentration of the dissolved gas in the water sample according to a given theoretical formula. Specially designed “regulator function ” and “water removal function ” makes the device has a more stable performance.
