Different types of fire pumps may have different faults and different frequencies. Today, let’s explore the reason what causes the fire pump overheating?. how to deal with it?
First, The motor
The fire pump motor overheat. First of all, it is necessary to consider whether the motor has broken down. For example, the connection of the relevant line is wrong, resulting in a rapid increase in the temperature of the motor. Or, the stator winding of the motor has a phase-to-phase short circuit, a turn-to-turn short circuit or local grounding. The motor is partially overheated, and the insulation is burnt out in severe cases; if the squirrel cage rotor is broken or defective, the temperature of the iron core will rise rapidly after the motor runs for 1 to 2 hours; or if the ventilation system fails, the fan should be inspected. Whether the direction of rotation is correct, whether the ventilation is blocked, or the bearing of the motor is worn, resulting in a rapid rise in the temperature of the iron core, the motor will be smoking, or even the coil burned up.
Second, Power supply
In general, fire pump voltage is high or low, will affect the operation of the fire pump motor, that is to say voltage fluctuation range should be +10% to -5% of the rating can cause overheating, this also means that, the voltage of fire pump operation need to be set according to the demand, In fire pump operation system, if the power supply voltage is up to standard, which determines the relative equipment of the fire pump is in normal operation.
Third, The water pump
Pump power does not match, electric power overload running for a long time, the motor temperature will rise; In addition, the pump started too frequently, non-stop work is also the cause of motor overheating, so it is very important to pay attention to the frequency of usage.
Fourth, The environment
The Environment of a fire pump is the key to determine fire pump failure frequency, if the fire pump is in a wet environment, the motor winding will be damp or covered with dust, grease and so on, then causes the insulation reduced. In usually, the environment is dusty, not cleaned, or the temperature is too high, etc. will cause various failures of the fire pump.
