Dalan Motor takes you to the 5 major culprits of the oil pump motor failure and 3 common fault solutions


The motor plays a vital role in industrial production and is an important guarantee for the stable operation of the equipment and the continuous development of industrial production. In daily production, we must pay great attention to the maintenance and repair work of the motor. The following is a small series of Dalan Motor to give you a solution to the 5 major causes of motor failure and 3 common faults, so as to reduce the occurrence of motor failure as much as possible to ensure the normal operation of the equipment. run.

The five major culprit of oil pump motor failure:

Overheat

Overheating is the biggest cause of motor failure. In fact, the other four reasons listed in this article are on the list, in part because they generate heat.

In theory, for every 10 °C increase in heat, the life of the winding insulation is halved. Therefore, ensuring that the motor is operating at the right temperature is the best way to extend its life.

2. Dust and pollution

All kinds of suspended particles in the air enter the inside of the motor and cause various hazards. Corrosive particles can wear parts, and conductive particles can interfere with component currents, which can accelerate overheating once they block the cooling channels. Obviously, choosing the right IP protection level can alleviate the problem to some extent.

3. Power supply problem

Harmonic currents caused by high frequency switching and pulse width modulation can cause voltage and current distortion, overload and overheating. This shortens the life of motors and components and increases long-term equipment costs. In addition, the surge itself can cause the voltage to be too high or too low. To solve this problem, we must continue to pay attention to and check the power supply.

4. Wet

Moisture itself can erode motor components. When the moisture and airborne particulate contaminants are mixed, it is a fatal injury to the motor, further shortening the life of the pump.

5. Improper lubrication

Lubrication is a matter of degree. Excessive lubrication or insufficient lubrication can cause harm. Also, pay attention to the contamination problems in the lubricant and the type of lubricant used.

3 major common motor fault solutions

1. Inspection and maintenance measures for motor heating problems

1) External measures

1 check to ensure the stability of the motor input voltage, and the voltage can not be too high;

2 Check to ensure that the working environment temperature of the motor is not too high, do a good ventilation and clean work to avoid affecting the heat dissipation of the motor;

3 Check that the mechanical equipment driven by the motor does not suffer from sluggish operation, etc., to avoid overload;

4 When it is found that the motor is overheated, it must stop in time to avoid the motor working under overheating.

2) Internal measures

1 Check to ensure that the internal stator, rotor and other components of the motor meet the installation requirements;

2 check to ensure that the lubrication state of the motor is good;

3 Check that the insulation parts inside the motor are good.

2. Inspection and maintenance measures for motor vibration problems

1) Mechanical measures

1 Check whether the linearity of the motor shaft is static and dynamic, and do a good job of lubrication;

2 Check to ensure that the fixed condition between the motor and the workbench meets the requirements;

3 Check the main running parts of the motor, such as bearings, for damage, and ensure that the performance of the motor components meets the working requirements.

2) Electromagnetic measures

1 Start with the power supply, check to ensure the balance of current and voltage;

2 Check the symmetry of the guaranteed winding resistance value;

3 Check that the correct wiring of the circuit contact parts such as the wiring head is ensured.

3. Maintenance and maintenance methods for motor noise problems

The motor noise problem is mainly caused by overheating of the motor or severe vibration of the motor. The main solutions are summarized as follows:

1) The staff should carefully and carefully check the assembly of the motor components to ensure that each component assembly can meet the standards of use. Once problems are found, the corresponding solutions are taken immediately to avoid unnecessary motor installation. Trouble.

2) It is necessary to fully guarantee the lubricity of the motor and prevent the motor from blocking.

3) The staff should pay special attention to whether each part of the motor and other parts are scratched.
