As an indispensable power supplier in people's production and life, many electric pump motors will have a very hot phenomenon in the process of use, but many times they don't know how to solve it. What is more serious is that they don't know what it is. The cause of the motor heating, the following Dalan motor editor teaches you to learn the five conditions of motor heating, this should be the first to grasp the use of the motor.
Overheating of the oil pump motor is generally caused by the following conditions: power failure, motor overload, phase loss operation, winding failure, cooling air passage blockage, etc.
1, power failure
If the power supply has a problem, it is common to cause the oil pump motor to heat up. What is wrong with the power supply? To check whether the three phases are balanced, whether the voltage fluctuation value is greater than or less than 10%, otherwise three-phase unbalanced current will be generated, causing the motor loss to increase and the motor to heat up.
2, motor overload
If the load is too large or the motor broom will cause the three-phase current to exceed the limit value, the pump motor will heat up. Pay attention to the load of the motor and understand the condition of the pump motor.
3, lack of phase operation
If the oil pump motor runs out of phase, first find the cause. If you don't know the professional, you can't solve it blindly. If it is a small problem, you can solve it yourself.
4, winding fault
The winding is a transformer with a primary winding and several secondary windings wound around the core. Since the number of turns of each secondary winding is different, the terminal voltages are different, so the multi-winding transformer can supply power to several different voltage consumers. The most commonly used in power systems is a three-winding transformer. It is more convenient to use three three-winding transformers to connect three different voltage transmission systems than to use two ordinary transformers, which is economical, takes up less space, and is easier to maintain. When the winding fails, it must be repaired in time.
5, cooling air passage blockage
If the cooling air passage is clogged, the oil pump motor will overheat. Therefore, the cooling air passage should be repaired in time to avoid the situation.
