1. What are the startup steps for a centrifugal pump? Answer: 1) Rotate the rotor for more than one full turn to confirm that there is no jamming ； 2) Check that the oil level in the oil cup is normal (above 1/2) ； 3) Confirm that the outlet valve is closed and open the inlet valve ； 4) Vent the pump body; close it once it meets the requirements ； 5) If seal water is to be used, supply the seal water ； 6) Start the motor; once the outlet pressure is normal, open the outlet valve to confirm that the motor pump is operating properly. 7) If the centrifugal pump is equipped with an auxiliary oil pump, establish oil circulation first before starting the pump ； Those that require a heat pump must have a qualified heat pump.
Starting a centrifugal pump: (1) Pre-startup preparations a: Verify that the pump’s protective cover is secure. b: Manually rotate the pump shaft several times to ensure smooth operation with no signs of friction. c: Check the quality of the lubricating oil, its level, and whether the cooling water is functioning properly. d: Ensure that the liquid level in the tank is normal; then open the pump’s inlet valve. e: Open the pump’s outlet drain valve to release air. f: Turn on the pump’s flushing and sealing water supplies. g: Confirm that the valve at the base of the pressure gauge is open. (2) Starting the pump a: Close the pump’s inlet and outlet drain valves. b: Start the pump and verify that its shaft rotates in the correct direction. c: Once the outlet pressure reaches the specified value, open the pump’s outlet valve. d: After running the pump for five minutes with no abnormalities, it is safe to leave; record the time at which the pump was started
