脱硫吸收塔系统常见故障
循环泵叶轮及泵壳磨损对吸收塔参数的影响脱硫系数的运行中,因浆液循环泵中介质为石灰石浆液,外加浆液中ph值变化较大,因此浆液循环泵的磨损在所难免。浆液在泵内高速运转流动,对泵壳产生一定的冲刷磨损,造成泵壳壁厚变薄、磨穿的情况。
The influence of wear of impeller and pump shell on absorber parameters in circulating pump During the operation of desulfurization coefficient, the wear of slurry circulating pump is unavoidable because the medium of slurry circulating pump is limestone slurry and the pH value of the added slurry varies greatly. The slurry runs at high speed in the pump, which results in erosion and wear of the pump shell, resulting in thinning and wearing of the shell wall.
解决方案:当浆液循环泵叶轮及泵壳磨损严重时,相应出现浆液循环泵电流减小,出力降低,将循环量减少,此时应停止运行,对该泵叶轮及泵壳进行特殊工艺防磨,当防磨工作处理且养护完毕,可在投入运行。
Solution: When the impeller and shell of slurry circulating pump are worn seriously, the current of slurry circulating pump decreases, output decreases and circulation volume decreases accordingly. At this time, the operation should be stopped. The impeller and shell of slurry circulating pump should be anti-abrasion by special technology. When the anti-abrasion work is processed and maintained, it can be put into operation.
