Common problems and analysis of micro water pumps

Usually, the machines that lift the liquid, transport the liquid or increase the pressure of the liquid, that is, convert the mechanical energy of the original motor into liquid energy to achieve the purpose of pumping the liquid, are collectively referred to as pumps. In the process of using miniature diaphragm pumps, there are always some simple and common problems. How can we solve these problems?

The flow gradually decreases.

Reasons: 1. The filter has been used for too long and the particles are blocked;

2. The sample port of the micro electric water pump is blocked by impurities.

The water in the micropump is abnormally interrupted.

Reasons: 1. Clean water pipes;

 2. The pipeline is blocked and the blockage is cleared;

3. Pipe rupture, repair or replacement,

4. The motor does not start and the circuit fails;

5. The water filter is blocked, the blockage is removed.

The pump runs violently or the noise increases abnormally.

Reason: 1. The installation angle is not fixed.

2. The motor or pump shaft is bent.

3. The access voltage is higher than the set voltage.

The pump motor works but does not produce water after starting.

Reasons: 1. The suction stroke is higher than the rated suction stroke of the pump,

 2. There are debris or particulate impurities in the pump;

Insufficient traffic.

Reasons: 1. The suction lift is too high;

2. There is air in the water pipe, the voltage is too low,

3. The motor speed is slow;

4. The actual lift of the pump exceeds the allowable lift.

When starting the micro water pump, the motor does not rotate.

Reason: 1. Poor contact between motor and carbon brush;

2. The matching switching DC power supply fails;

3. The battery or the battery is out of power;

4. The circuit is in poor contact.

The above are the common problems and causes of micro water pumps. Everyone should pay attention to the maintenance and repair of the pump in the daily use process to prolong its service life.
