Catalytic cracking distillation three-path cycle

In a catalytic cracking distillation system, the reasons why the slurry pump fails to deliver sufficient flow may include the following: 1. Slurry pump malfunction: There may be faults within the slurry pump itself, such as motor damage or bearing failure, which prevent the pump from operating normally and pumping the slurry. 2. Pump inlet blockage: There may be blockages in the pipes or valves leading to the slurry pump; for example, foreign objects or deposits in the pipes can prevent the flow of the slurry, preventing the pump from sucking in the slurry properly. 3. Excessive resistance at the pump outlet: Excessive resistance in the pipes or valves at the pump outlet prevents the pump from delivering the slurry to its intended destination, thus preventing an increase in flow rate. 4. Other equipment failures: In the catalytic cracking distillation system, in addition to the slurry pump, there are other key pieces of equipment such as condensers and heat exchangers. If these devices fail, it may prevent the slurry pump from operating properly. To address the issue of the slurry pump suddenly failing to deliver flow, a thorough inspection and diagnosis are required to identify the specific cause of the fault, and appropriate repair measures should be taken promptly to ensure the normal operation of the catalytic cracking distillation system. At the same time, regular maintenance of equipment and enhanced inspection efforts can effectively prevent and reduce the occurrence of failures. .

At temperatures below 200 degrees, water in the system causes pump cavitation

How long did it cycle before the sudden depletion occurred? Considering that excessive water accumulation in the pipeline during circulation can cause the pump to go into vacuum, open-circuit circulation is used for dehydration while fluid is being fed in and removed at the same time ； Alternatively, there may be too many impurities in the pipeline or the pump inlet filter is clogged; try shutting down the pump and removing it for cleaning.

There is a lot of debris in the filter at the inlet of the slurry pump during operation； The raw material contains a high amount of water, and cavitation during the heating process prevents an adequate increase in output

It was cycling for several hours, and then suddenly it stopped producing any output

There is no problem with the process or the slurry pump itself; it’s most likely that water is present
