1, the preparation before installation 1) Before starting the pump should be carefully checked in the transport, storage, installation process without distortion or damage, the fastener is loose or off. 2) Check the cable for damage, breakage and other phenomena, if damaged, need to be replaced to avoid leakage. 3) Check the power supply is safe and reliable, the rated voltage must be consistent with the nameplate. 4) with a megger to check the motor stator winding cold ground insulation resistance value of not less than 50 megohms. 5) Check the oil in the oil chamber is suitable for the unit in the vertical position when the oil level should be flush with the filler. 6) The submersible pump with cooling water cover must ensure continuous injection of clean cold water and make sure the drain is open when it is powered on. The cooling water should flow from the lower end to the upper end of the other side. 2, Matters needing attention After the pump is running, you should always observe the power supply voltage, current, pump flow and pump vibration is normal, such as the occurrence of one of the following conditions, should immediately stop checking: 1) working current exceeds the rated current. 2) Rated head, the flow rate reduced by 20% or more intermittent water. 3) The supply voltage is too high or too low. 4) The pump has obvious vibration or noise 3, Installation Precautions 1) Electrical Wiring: Electrical wiring should be performed by the official electrician in accordance with the circuit diagram. Insulation resistance should be checked at any time during the installation. Insulation resistance of the motor should not be less than 5 Megohm after installation . Lift the pump, jog observation steering, clockwise from the motor to look down the pump clockwise, such as steering is wrong, replace any two three-phase power connector. 2) Do not use the pump cable as a mounting and lifting rope, to avoid danger. 3) The pump should be vertically immersed in the water, not allowed to horizontal, can not sink into the sludge, the pump moves, you must cut off the power 4, storage precautions 1) After the pump is used for many times, it must be placed in clean water to run a few minutes to prevent Leave the sediment in the pump to ensure the pump is clean. 2) When not in use for a long time, remove the electric pump from the water to reduce the chance of damp of the motor stator windings and increase the service life of the electric pump. 3) Under normal working conditions, the pump should be maintained after 1 year of operation, replace worn parts, check the fastening status, replace or replace the bearing grease and insulating oil in the oil chamber, and ensure that the electric pump Well run.
