Paper Mill Vacuum Pump Start-up Precautions

In paper production line, the Vacuum Pump serves as the critical component that generates the necessary suction for sheet formation and dewatering. The reliable performance of this Vacuum Pump directly impacts the paper’s quality and the machine’s overall efficiency. From the forming fabric to the press section, a robust Vacuum Pump system is fundamental for achieving optimal dryness and consistent production speed.

Key pre-operational checks include:

Complete all standard pre-start inspections for the vacuum system, including the vacuum pump, filtrate pump, and white water tanks.

Verify the correct open or closed position of all suction, connecting, and isolation valves on the vacuum pump lines.

For new pipelines, ensure the inlet air filter screen is installed and intact to prevent metal debris or weld slag from damaging the pump impeller.

After initial runs, inspect and clean this filter screen multiple times until the pipeline is clean, then remove the screen to avoid clogging.

Fill both the main white water tank and the vacuum pump’s dedicated seal water tank to the required level before starting.
