When a vertical multi-stage pump malfunctions, some people don't know how to handle it. Today, we will summarize the measures that should be taken when an accident occurs; The earlier we adopt the correct approach, the more we can avoid larger problems.
1. During operation, the pump suddenly leaks air. If a leakage point is immediately discovered, vacuum sealing mud can be used to seal the dew point. After the work is completed, it can be dealt with again.
2. You can press the accident button or disconnect the pump stop switch, and the backup pump will immediately start working to ensure normal water supply. When the common pump linkage is not in use, manually start it immediately.
3. If the current of the faulty pump is found to be zero, the outlet butterfly valve should be interlocked and closed, and the pump should not reverse; If not possible, manually close the outlet butterfly valve.
4. When the temperature is relatively high, the water is cut off or the power is cut off. When additional equipment is needed, there is a self-contained water tank or other water pipes connected to ensure safety.
5. After using a vertical multi-stage pump for a period of time, it is necessary to clean it thoroughly and take protective measures.
