If you do not know, the following small series We will introduce centrifugal pump operation requires attention. Centrifugal pump operation precautions 1, prohibit the anhydrous operation, do not adjust the suction port to reduce the displacement, prohibit the operation of the flow is too low; 2, monitoring the operation of the process to completely prevent the stuffing box leak, replace the stuffing box with new Packing; 3, to ensure that the mechanical seal flush water, water-cooled bearings prohibit the use of excessive water flow; 4, do not use too much lubricant; 5, according to the recommended cycle of inspection. Establish operating records including operating hours, packing adjustments and replacements, adding lubricants and other maintenance measures and times. Centrifugal pump suction and discharge pressure, flow, input power, lotion and bearing temperature and vibration conditions should be measured regularly recorded. 6, Centrifugal pump host is relying on the atmospheric pressure will be low water pumping to a high place, while the atmospheric pressure can only support about 10.3m of water column, so the centrifugal pump away from the surface of the host 12 meters can not work. Above is the centrifugal pump in the operation should pay attention to the matter, I hope everyone at the time of operation can provide a reference.
