1. Analysis of Common Faults, Causes and Treatment of Small - sized Fountain Submersible Pumps
2. Rewinding of Stator Winding of Submersible Pump Motor
(1) In order to avoid or reduce assembly error caused by the rotation of the rotor is not flexible, before disassembling the motor, in the front and rear ends of the joint with the machine at the sign with the child, to be repaired as is.
(2) dismantling group, we should pay attention to protecting the core, to avoid silicon steel tilt, shift, slot angle burr and other phenomena. A good method of stitching is to first cut the coil from one end with a diagonal pliers, and then use the forceps to pull out the other end.
(3) according to the size of the required winding coil winding system to ensure that the winding end of the gap and the coil into the slot.
(4) embedding using the "three-plane method", that is embedded in one phase and then embedded another phase, so that the end of the formation of "three-dimensional plane":
Embedded to pay attention to: ① the first two "hanging" the location of the coil to be appropriate to ensure that embedded in other coils do not scratch when the stator core;
② under the coil with less crossed plate, so as not to damage the coil insulation;
③ phase insulation paper to be inserted in place, two-phase coil to be strictly separated;
④ For oil-immersed and water-filled motor, the coil (including the end) can not be compacted, so that oil (water) can flow for the winding heat.
(5) handle the joint insulation. Then peeling welding, and clear the sharp corners, burrs and residual welding fluid; and then with a half-stack of polyethylene with a layer of two layers , With about 2 times the tension of the self-adhesive tape semi-wrapped 6-layer (joints do tight seamless), and finally with a polyethylene adhesive tape or polyester tape with semi-folded package 2 layers as a mechanical protection.
(6) Keep the assembly clean. Carefully adjust the bottom of the "limit screw", so that the rotation of the rotor freely, and tighten the lock nut. Install the end cap in its original position, taking care not to damage the rubber sealing ring in the sealing box. Integral sealed box can only gently push the assembly, not percussion.
