5. Maintenance Recommendations
To ensure long-term stable operation of the 350QH40-90 submersible mixed-flow pump, we recommend the following maintenance measures
5.1 Regular Inspection
Check the pump’s operating condition monthly, including the motor’s insulation resistance, cable integrity, and any looseness or damage to the pump body.
Cleaning and Lubrication: Clean the pump quarterly to remove debris and deposits. Lubricate key components like bearings to ensure smooth operation.
5.2 Seal Inspection and Replacement
Inspect the seal chamber and oil quality every six months. If oil emulsification or water sedimentation is found, promptly replace the 10-30 grade oil and mechanical seal.
5.3 Annual Maintenance
Conduct comprehensive maintenance annually or after 2,500 hours of operation. This includes disassembling the motor, cleaning all parts, removing scale and rust, and replacing damaged components.
5.4 Insulation Testing
Regularly measure the insulation resistance between the pump’s stator winding and housing using a megohmmeter. Ensure it is above 1 megohm, with a minimum of no less than 0.5 megohm.
5.5 Rust Prevention
Apply rust prevention treatment to the pump’s surface annually, repainting as needed based on corrosion. Internal rust prevention is applied depending on the pump model and corrosion condition.
5.6 Proper Storage
When not in use for long periods, avoid submerging the pump. Store it in a dry, well-ventilated indoor area. Protect the rubber cable from direct sunlight to prevent aging.
By following these maintenance steps, the 350QH40-90 submersible mixed-flow pump will maintain optimal performance, providing reliable support for the client’s water management needs.
