Why has the outlet pressure of the slurry pump decreased compared to before?
Thread Content
The outlet pressure of the slurry pump has decreased. What could be the reasons?
It’s likely that the filter at the pump inlet is clogged; remove it and clean it.
Is the pressure in the outlet’s backflow system low?
There’s nothing wrong with the filters; they were just cleaned. Additionally, we encountered the same issue when switching to the backup pump.
Is it dirty when cleaning the filter? It’s also possible that the filter in the tower is clogged ； It’s also possible that the pump inlet pipeline has clogged.
Check if there are any changes in temperature and viscosity
1. Changes in the process flow; 2. Changes in the opening degree of the control valves at the top and bottom of the tower; 3. Coking or blockages in the pipelines or heat exchangers, which are then removed; 4. Changes in the composition of the slurry
Consider whether there is a leak in the rear heat exchanger
What is the change in pressure, from one value to another? Stating the parameters clearly helps solve problems.
The flow rate is low; the inlet filter is clogged, the pipelines are coked, and the viscosity of the slurry increases. The pressure gauge’s pressure lead pipe has cooled down and solidified. Changes in the export process system
