Regarding the issue of pipeline blockage in a high-flow, low-cavitation multi-stage pump, we should take swift action to ensure the system's normal operation and safe production. Below are the handling methods and suggestions for this situation.

I. Confirming the Blockage

First, determine the specific location and extent of the blockage. By checking the pipeline's exterior, listening for sounds, or observing pressure changes, the location and cause of the blockage can be preliminarily determined.

II. Preparations Before Safe Handling

Before handling the blockage, operational safety must be ensured. The pump should be turned off and the power disconnected to prevent accidental startup during operation. Protective clothing, safety glasses, and other protective equipment should also be worn.

III. Handling the Blockage

1. If the blockage is in a pipe bend or narrow section, a pipe cleaner or high-pressure air pump can be used to clear it. During operation, attention should be paid to the force and angle to avoid damaging the pipeline.

2. If the blockage is severe, it may be necessary to dismantle part of the pipeline for processing. During this process, attention should be paid to the pipeline's sealing and connectivity to ensure normal operation after reinstallation.

IV. Preventing Recurrence of Blockage

After handling the blockage, the cause of the blockage should be analyzed, and corresponding measures should be taken to prevent recurrence. For example, regularly cleaning the pipeline, installing filters, or checking the fluid quality.

V. Precautions

1. During the handling process, ensure good ventilation in the surrounding environment to avoid the generation of harmful gases or vapors.

2. If the handling process involves hazardous substances, appropriate emergency handling preparations should be made.

3. During operation, follow relevant safety regulations and operating procedures to ensure personnel safety.

VI. Summary

To handle pipeline blockages in high-flow, low-cavitation multi-stage pumps, first confirm the blockage situation, then use safe and effective handling methods. During the handling process, pay attention to safety and take measures to prevent recurrence. Also, pay attention to the relevant precautions to ensure the safety of personnel and the environment.

Through the above steps and handling methods, we can effectively solve the problem of pipeline blockage in high-flow, low-cavitation multi-stage pumps, ensuring the normal operation and safe production of the production line.
