When Operating A Centrifugal Pump, The Following Points Should Be Noted

① Do not operate without water, do not adjust the suction port to reduce displacement, and do not operate at low flow rates;
② Monitor the operation process, completely prevent leakage of the packing box, and use new packing when replacing the packing box;
③ Ensure that the mechanical seal has sufficient flushing water flow, and excessive water flow is prohibited for water-cooled bearings;
④ Do not use too much lubricant;
⑤ Inspect according to the recommended cycle. Establish operating records, including operating hours, adjustment and replacement of fillers, addition of lubricants, and other maintenance measures and time. The suction and discharge pressure, flow rate, input power, temperature of washing solution and bearings, as well as vibration of centrifugal pumps should be regularly measured and recorded.
⑥ The main engine of a centrifugal pump relies on atmospheric pressure to pump water from low points to high points, and atmospheric pressure can only support up to about 10.3m of water column, so the main engine of a centrifugal pump cannot work when it is 12 meters away from the water surface.
