我厂液氯的计量,原来一直采用油压秤,将油压秤安装在有Ω弯管架设的液氯贮槽下面,解决了液氯的计量问题,但由于油压秤内工作液体受昼夜温差的影响,造成测量误差高达10％左右,维修工作量也很大。由于这种原因,我们在七三年十一月份在2＃液氯贮槽上试装了一台电子秤,实践证明,用电子秤代替油压秤来计量液氯,解决了温差的影响,並且便于集中管理,最大误差一般在±2％左右,有时可达±1.5％以下。
I plant liquid chlorine measurement, the original has been using hydraulic scale, the hydraulic scale installed in the o-shaped tank has been set up below the liquid chlorine tank to solve the problem of liquid chlorine measurement, but the working fluid within the hydraulic scale by day and night The impact of temperature difference, resulting in measurement error of up to 10%, the maintenance workload is also great. Because of this, we tried out an electronic scale on a 2 # liquid chlorine storage tank in November of November, and proved that replacing electronic scales with hydraulic scales to measure liquid chlorine solved the influence of temperature difference, And to facilitate centralized management, the maximum error is generally ± 2%, and sometimes up to ± 1.5% or less.
