1, Before using the pump should be fully checked in the transport, storage process is not bad, if damaged, should promptly replace the living professionals to repair. 2, before use to install leakage, phase loss, over-current overload protection device. 3, pipeline booster pump operation, check the insulation resistance should be greater than 20MΩ, otherwise it should be dried. 4, the pump inlet and outlet flanges and flanges with rubber seals and solid connections. 5, in the pump inlet and outlet piping installed on the control valve, and flange near the exit of the installation of pressure gauge. 6, open the inlet control valve, so that the sealed chamber (pump) filled with liquid, to determine the correct steering pump, open the control valve outlet pipe on the control valve, the pump in the vicinity of the rated point of operation. Pipeline pump repair and maintenance 1, Regularly check the organization between the pump winding and the chassis insulation resistance, insulation resistance should be greater than 20MΩ, or must take appropriate measures to meet the requirements before use. 2, 2000 hours after normal use, the pipeline centrifugal pump maintenance, bearings to replace the oil. 3, when the temperature below 4 ℃ the best antifreeze work, so as to avoid the pump body rupture. 4, the pipeline booster pump for a long time do not use, should be removed from the pipeline, drain the net water pump, the main components scrub clean rust-proof dry treatment, placed in a dry and ventilated place, and safekeeping.
