Electromagnetic pump is a kind of liquid transportation device using electromagnetic principle, which is widely used in chemical industry, medicine, food and other fields. Due to its special working principle and long-term use, some malfunctions may occur. The following are some common electromagnetic pump failures and their solutions.

1. common faults

1. No liquid or insufficient flow: it may be caused by air leakage in the suction pipe, gas in the pump cavity, blockage of the inlet pipe, etc.

2. Excessive noise: it may be caused by damage to the motor bearing, excessive friction between the rotor and the stator, or high motor speed. The noise may be caused by bearing wear, loose impeller or motor failure.

3. Motor heating: may be due to overload, motor heat dissipation or motor winding short circuit and other reasons.

4. The electromagnet does not work: it may be caused by power supply problems, electromagnet damage or line failure.

5. The electromagnetic pump cannot work normally after starting: this may be caused by power failure or circuit connection error.

Leakage phenomenon: This may be caused by aging or damage to the seal.

2. Solution

1. The solution of no liquid or insufficient flow

Check whether the suction pipe is leaking and tighten, remove the gas in the pump cavity, and clean the blockage of the inlet pipe.

2. The solution of excessive noise

Check whether the motor bearing is damaged. If it is damaged, replace it in time. Adjust the gap between the rotor and the stator to avoid excessive friction. Adjust the motor speed to the appropriate range. The way to solve this problem is to check the condition of the bearing first. If the bearing is worn, it should Replace it in time. Secondly, check whether the impeller is installed tight, if loose, should be adjusted. Finally, check whether the motor is operating normally. If there is any abnormality, it should be repaired or replaced in time.

3. The solution of motor heating

Check whether it is overloaded. If it is overloaded, adjust the process or add heat dissipation measures; clean up the dust inside the motor to maintain a good heat dissipation effect; check whether the motor winding is short-circuited, and repair it if there is a short circuit.

4. Solving method of electromagnet not working

Check whether the power supply is normal, if the power supply problem needs to be repaired; check whether the electromagnet is damaged, if it is damaged, replace it; check whether the circuit is faulty, if it is faulty, repair it.

5. Solution to the problem that the electromagnetic pump cannot work normally after starting

First check whether the power supply is normal to ensure that the voltage and frequency meet the equipment requirements. Second, check whether the circuit connection is correct, including the power line, control line and ground line. If a fault is found, it should be replaced or repaired in time.

6. The solution of leakage phenomenon

Check the state of the seal, if found damaged or aging, should be replaced in time. In addition, it should be ensured that the installation position of the seal is correct and the tightness of the seal is appropriate to avoid leakage problems.

3. preventive measures

1. Regularly check the performance of the electromagnetic pump, such as the discovery of abnormal timely processing.

2. Keep the electromagnetic pump and its surrounding environment clean and prevent dust and other pollutants from entering the pump.

3. Operate the electromagnetic pump according to regulations to avoid overload and long-term continuous work.

4. Regularly check the lubrication of the motor bearing to ensure the good operation of the bearing.

In short, understanding the common faults and solutions of electromagnetic pumps is very important for the maintenance and repair of electromagnetic pumps. Through careful inspection and correct operation, we can ensure the normal operation of electromagnetic pumps, improve work efficiency, ensure the smooth progress of industrial production, correctly operate and maintain electromagnetic pumps, and deal with faults in time, which can ensure the long-term stable operation of electromagnetic pumps and improve production efficiency.
