First, unable to start $ j9 N & S should first check the power supply situation: whether the connector connection is solid; switch contact is tight; whether the fuse is blown; If there is an open circuit, poor contact, the fuse blown, lack of phase, should identify the cause and timely repair. Second, check if it is a mechanical failure of the pump itself, common causes are: packing is too tight or clogged with debris between the impeller and the pump body; pump shaft, bearings, leak ring rust live; severe shaft bending and so on. Remedy: relax the filler, clear the diversion trough; open the pump body to remove debris, rust; remove the pump shaft to correct or replace the new pump shaft. 4 b * {& w Second, the supporting motor overheating 1 b, ~ 4 Z (c "Z1 r $ A7 Y + [0 u; G2 M9 C) {g There are four reasons. First, the power of the reasons: High or low, under certain load, if the voltage fluctuation range should be beyond the rated value of + 10% to -5% outside the motor will cause overheating; power supply three-phase voltage asymmetry, power supply three-phase voltage imbalance of more than 5 %, Will lead the winding overheating; lack of phase operation, the experience shows that agricultural motor is burned more than 85% due to lack of phase operation, the motor phase loss protection device should be installed.Second, the pump reasons: the use of power is not complete, the pony Pull the cart, the motor overload operation for a long time, so that the motor temperature is too high; start too often, the fixed short-term or intermittent work of the motor continuous work should be limited to the number of starts, the correct choice of thermal protection, according to the rated motor Use. Third is the reason of the motor itself: the connection error, will be mistakenly connected to the Y-shaped Y-shaped, so that the motor temperature rose rapidly; stator windings have short-circuit between the short circuit or turn to turn the ground, light motor Overheating, serious insulation burnout; broken squirrel cage rotor or defective, the motor running for 1 to 2 hours, the core temperature rises rapidly; ventilation system failure, the fan should be checked for damage, rotation is correct, the ventilation holes are Jamming; bearing wear, the rotor eccentric heartburn make the rotor core wipe out the metal percussion sound, the core temperature rises rapidly, serious motor smoke, or even coil burned.Four reasons for the work environment: the motor winding damp or dust, Oil and other attached to the winding, resulting in reduced insulation. Insulation resistance should be measured and cleaned motor, drying; Ambient temperature is too high. When the ambient temperature exceeds 35 ℃, the inlet temperature is high, the motor temperature will be too high, Should try to improve their working environment, such as scaffolding sun shade, etc. Note: due to electrical reasons for failure, should obtain a professional qualification certificate of electrical maintenance, illiterate people can not be blindly repaired to prevent personal injury accidents.

Remedy: Replace the bearing; Remove the back cover, install the gasket between the bracket and the bearing seat; Investigate the pump shaft or adjust the concentricity of the two shafts; Adjust the tightness of the tape properly; Fill with clean butter and butter Accounting for about 60% of the gap within the bearing; clear the balance hole plug. * K.
