Precautions For Operation Of Centrifugal Pump
TIME：2024-06-03 Author：admin Views：
When we use the centrifugal pump , we need to pay attention to the following :
● No running without water is allowed, do not adjust the suction port to reduce the displacement and operation at a too low flow rate is prohibited.
● Monitor the operation process to completely stop the stuffing box from leaking, and use new packing when replacing the stuffing box.
● The main body of a centrifugal pump relies on atmospheric pressure to pump water from a low place to a high place, and atmospheric pressure can only support a water column of about 10.3 m at most, so the main body of a centrifugal pump cannot work 12 m above the water surface.
● No running without water is allowed, do not adjust the suction port to reduce the displacement and operation at a too low flow rate is prohibited.
● Monitor the operation process to completely stop the stuffing box from leaking, and use new packing when replacing the stuffing box.
● Ensure that mechanical seals have sufficient water flow for flushing, and water-cooled bearings are prohibited from using excessive water flow.
● Do not use too much lubricant;
● Carry out inspection according to the recommended cycle. Establish operation records, including hours of operation, adjustment and replacement of packing, addition of lubricant and other maintenance measures and time. The centrifugal pump suction and discharge pressures, flow rate, input power, wash liquid and temperatures of bearings, and vibration should be measured and recorded periodically.
