【Abstract】：
The following points should be noted when operating the centrifugal pump:
①It is forbidden to run without water, do not adjust the suction port to reduce the displacement, and it is forbidden to operate at a too low flow rate;
②Monitor the operation process, completely prevent the stuffing box from leaking, and use new packing when replacing the stuffing box;
The following points should be noted when operating the centrifugal pump:
①It is forbidden to run without water, do not adjust the suction port to reduce the displacement, and it is forbidden to operate at a too low flow rate;
②Monitor the operation process, completely prevent the stuffing box from leaking, and use new packing when replacing the stuffing box;
③Ensure that the mechanical seal has sufficient water flow for flushing, and it is forbidden to use excessive water flow for water-cooled bearings;
④ Do not use too much lubricant;
⑤ Check according to the recommended cycle. Establish operation records, including operation 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 the washing liquid and bearing, and vibration of the centrifugal pump should be regularly measured and recorded.
⑥The main unit of the centrifugal pump relies on atmospheric pressure to pump low water to high places, and the atmospheric pressure can only support a water column of about 10.3m at most.
