浆液循环泵出口压力低的原有和处理办法:
1.循环泵入口滤网有异物堵塞导致入口压力低流量下降,切循环泵进行冲洗入口堵塞。
2.循环泵入口处浆液沉淀导致入口流量低,查看吸收塔搅拌器运行情况及调整浆液密度ph值,切循环泵进行冲洗入口。
3.吸收塔液位低,提高液位,。
4.吸收塔密度降低,导致压力降低,正常现象。
5.循环泵入口进入氧化空气,停用附近氧化分支管,观察效果,确认后停机改造。
6.循环泵入口泄漏造成入口压力降低,对应补漏。
7.循环泵入口阀门开不到位造成入口流量变小,调整入口门行程。
8.压力表失准,体测压力计表
Possible causes and treatment of low outlet pressure of slurry circulating pump
The original and treatment method of low outlet pressure of slurry circulating pump:
1. The inlet filter screen of the circulating pump is blocked by foreign matters, which leads to low inlet pressure and low flow. Cut the circulating pump for flushing and the inlet is blocked.
2. Low inlet flow is caused by slurry precipitation at the inlet of the circulating pump. Check the operation of the agitator in the absorption tower and adjust the pH value of slurry density, and switch the circulating pump to flush the inlet.
3. If the liquid level of absorption tower is low, increase the liquid level,.
4. The density of absorption tower decreases, which leads to the decrease of pressure and normal phenomenon.
5. The oxidation air enters into the inlet of the circulating pump. Stop the nearby oxidation branch pipe, observe the effect, and stop the machine after confirmation.
6. The inlet pressure of the circulating pump decreases due to the leakage at the inlet of the circulating pump, and the leakage shall be repaired accordingly.
7. If the inlet valve of circulating pump is not opened in place, the inlet flow will be reduced, and the stroke of inlet valve shall be adjusted.
8. The pressure gauge is out of alignment, and the body pressure gauge is measured
