Prevention of submersible sewage pump motor water coup

Taking into account the submersible sewage pump motor diving work for a long time, so the prevention of motor water is particularly important, once the motor water is likely to damage the submersible axial pump bearing and winding insulation, burn the motor, not only increase the maintenance time and maintenance costs, Also delayed the normal work. It can be seen that the prevention of water intake is the key to ensuring that the motor is sealed. Reasonable prevention of submersible sewage pump motor water.
    (1) regularly check the pump motor winding on the ground insulation resistance. Regular inspection of the insulation resistance of the pump motor windings, the value should be greater than the different temperature of the submersible axial pump insulation value requirements, or should be disassemble maintenance, if the water to be dry, and should check whether the ground is strong.
    (2) check the oil chamber sealing situation. Sewage pump in the prescribed medium after six months, should check the oil chamber sealing situation, such as oil found in water submersible axial pump or milk emulsion, according to the provisions of cleaning the oil room, if necessary, replace the mechanical seal, Conditions of the poor use of the sewage pump should be routinely overhauled. If the oil after the operation of a very short time to leak the probe that alarm, mechanical maintenance should be overhauled, such as mechanical seal damage, should be replaced or overhaul.
    (3) Check whether there is a leak in the service seal. Submerged pump leakage failure, mostly due to the aging of the sealing device, due to wear, then replace the new seal can achieve the purpose of preventing water.
    (4) Check if the leaky probe is out of order. Leakage probe failure, generally because the drain probe wire blown, overhaul the first leaky probe diving axial pump copper tube filled with epoxy resin filler, and then put the lead wire connected to each lead wire conductive And insulated from each other, and finally in the copper tube pouring epoxy resin, so to re-create a leaky probe. The lead wire on the probe is firmly connected with bolts and leads to the external junction box with the motor power cord, which ensures effective monitoring of the water intake problem.
