排涝泵价格


Reasons for power supply: The voltage is too high or low. Under certain load, if the voltage fluctuation range should be outside the + 10% to -5% of the rated value, it will cause the motor to overheat; The phase-to-phase imbalance of the electric voltage exceeds 5%, which can lead to overheating of the windings; experience of phase loss operation indicates that more than 85% of the agricultural motors are burned due to phase loss operation. Phase loss protection devices should be installed in the motor.

Reasons for pumps: Use of unmatched power, small horse-drawn carts, long-term overload operation of the motor, which makes the temperature of the motor too high; starting too frequently, and the price of the drainage pump is short-term or intermittent work system continuous operation. Should limit the number of starts, the correct selection of thermal protection, according to the rated value on the motor.

Causes of the motor body: wrong connection method, wrongly connecting the △ shape to the Y shape, causing the temperature of the motor to rise rapidly; the stator windings have phase-to-phase short circuit, inter-turn short circuit, or local grounding; the motor is locally overheated when light, and the insulation is burned out in severe cases. The squirrel-cage rotor is broken or defective, and the core temperature rises rapidly when the motor runs for 1 to 2 hours; if the ventilation system fails, check whether the fan is damaged, the rotation direction is correct, and the ventilation holes are blocked; the bearings are worn and the rotor is eccentrically swept The bore causes the iron core phase of the stator and rotor to wipe out a metal impact sound, the core temperature rises rapidly, and in severe cases, the motor smokes and the coil burns out.

Reasons for the working environment: the motor winding is damp or dust, oil, etc. are attached to the winding, causing the insulation to decrease. The insulation resistance of the motor should be measured and cleaned and dried; the ambient temperature is too high. When the ambient temperature exceeds 35 ° C, the inlet air temperature is high, which will cause the temperature of the motor to be too high. Try to improve its working environment. Such as shed shading. Note: If there is a failure due to electrical reasons, you should ask an electrician who has obtained a professional qualification certificate to repair it. A person who knows nothing about it should not repair it blindly to prevent personal injury.
