How to avoid abnormally turning on the pump power supply voltage?

[Avoid frequent switching]Do not switch the Solar seawater pump frequently. This is because the recirculation occurs when the electric pump is stopped. If it is turned on immediately, the motor load will start, causing the starting current to be too high and the Winding to be burned out. Due to the large current at start-up, frequent start-up will also burn the Solar seawater pump work windings. [Do not let the Solar seawater pump work for a long time]In order to avoid long- Term addition operation of the Solar seawater pump, do not pump water with a large amount of sand and observe whether the current value is on the name plate. If it is found that the current is too large, stop the inspection. In addition, the dehydration The operation of the electric pump should not be too long, so as to prevent the motor from overheating and burning. [The direction of rotation of the motor is correct] The direction of rotation of the motor should be clarified. Solar seawater pu Mps that can discharge water during forward and reverse rotation. However, when reversing, the water output is small and the current is large. If the reversal time is long, the motor winding will be damaged. [Cable line installation and insulation resistance requirements of Solar seawater pump]When installing the Solar seawater pump, the cable should be overhead and the power cord should not be too long. Do not force the cable when the Solar seawater pump is launched or raised, so as not to cause the power cord to Break. Do not sink into the mud when the Solar seawater pump is working, otherwise it will cause poor heat dissipation of the motor and burn the motor windings. When installed, the insulation resistance of the motor should not be less than 0.5 megohms.
