This guide provides vital preparations and pro tips for water cooling Roots vacuum pumps. From checking cooling systems to precise pressure control, optimize your pump’s operation to maximize productivity and equipment lifespan.
Pre-operation water tank inspection
Prior to operation, inspect the water level in the water tank of the flushing pump (primary pump) and ensure it reaches at least 3/4 capacity. If the level is below this mark, refill it accordingly.
Water quality inspection
To ensure optimal performance and avoid costly breakdowns, it is crucial to pay attention to the water quality in the tank. Before operation, carefully inspect the water’s cleanliness, avoiding any use of water containing sediments or impurities. It is essential to prevent pipe blockages and minimize wear on the water pump’s impellers, reducing stress on the motor. By embracing this proactive approach, you can enjoy smooth and efficient operation while significantly extending the flushing pump’s overall lifespan.
Lubricating oil inspection
During the inspection, ensure that the lubricating oil level in both the intermediate and main pump bodies is at least 3/4 of the oil window. Additionally, carefully examine the lubricating oil for any abnormalities. If the Roots pump exhibits a milky or black coloration with a notable presence of impurities, promptly replace with new lubricating oil.
Circulating water cooling system inspection
Ensure the integrity of the circulating water cooling system for both the intermediate pump and main pump of the Roots pump. Open the inlet and outlet valves of the cooling water and carefully observe the water circulation to ensure its proper functioning.
Drain valve inspection
Verify whether the drain valve at the bottom of the intermediate pump’s buffer tank is securely closed.
Electrical circuit and control cabinet inspection
Thoroughly examine the electrical circuitry of the vacuum pump unit to ensure its proper functioning. Additionally, check the control cabinet for any indications of anomalies and verify if all controls and indicators are operating normally.
Pressure Gauge inspection
Verify the pressure gauges of the vacuum pump unit to ensure that the starting pressures for both the intermediate pump and main pump are within the prescribed ranges. The intermediate pump should have a starting inlet pressure of 0.065 MPa or higher, while the main pump should have a starting inlet pressure of 0.085 MPa or higher.
After thoroughly conducting all the mentioned inspections, start the water cooling vacuum pump unit with confidence.
