Pipeline centrifugal pump maintenance is essential to ensure the efficient and safe operation of the system. Here's a detailed guide on how to properly maintain such pumps:
1. **Operation and Maintenance Procedures**:
(1) Before starting the pump, make sure the inlet pipe is completely filled with liquid. Never run the pump for an extended period under cavitation conditions, as this can cause severe damage to the impeller and other internal components.
(2) Regularly monitor the motor current to ensure it does not exceed the rated value. Excessive current may indicate issues like overload or electrical faults.
(3) If the pump is operated continuously over a long period, mechanical wear may occur. Pay attention to any unusual noise or vibration. If detected, stop the pump immediately and inspect the unit. Replace worn-out parts, such as seals or bearings, if necessary. It is recommended to perform a full overhaul once a year to maintain optimal performance.
2. **Mechanical Seal Maintenance**:
(1) The mechanical seal must be lubricated with clean fluid free from solid particles. Contaminants can lead to premature failure of the seal.
(2) Avoid operating the mechanical seal in a dry grinding condition, as this can cause excessive heat and damage the sealing surfaces.
(3) If the medium being pumped has high viscosity or tends to crystallize, it is important to use steam to flush the seal after shutting down the pump. This prevents clogging and protects the mechanical seal from damage during the next startup.
