Key Points for Safe Use of Miniature Brushless DC

The biggest feature of the micro DC water pump is that it is small and light, easy to install, low noise, low power and high efficiency. Widely used in landscaping, grassland irrigation, aquaculture, small household appliances, etc., covering many fields such as industry, agriculture, chemical industry, transportation, IT, construction and home appliances.

In order to ensure the normal service life of the micro brushless DC water pump, maintain stable performance and avoid accidents and losses during use, the following points should be paid attention to when using:

1. Avoid frequent switching:

Do not switch on and off the miniature submersible pump frequently. This is because backflow will be generated when the electric pump stops. If it is turned on immediately, the motor load will start, resulting in excessive starting current and burning of the winding. Due to the large current when starting, frequent starting will also burn out the motor winding of the submersible pump:

2. The product is a centrifugal pump and must be installed below the liquid level;

3. It is strictly forbidden to use liquids with 0.35mm impurities and magnetic particles;

4. It is strictly forbidden to use when there is no liquid in the pump, so as to prevent the high-temperature wear of the internal structure caused by the high-temperature rotation of the liquid;

5. When using in a low temperature environment, please ensure that the liquid used will not freeze or be very viscous;

6. It must meet the situation of low temperature frost heave to prevent the inside of the water pump from freezing and bursting in winter;

7. The internal clearance of the DC brushless water pump is precisely controlled, please do not beat it, otherwise it will cause increased noise and vibration;

8. Do not let the brushless DC water pump work overloaded for a long time;

In order to avoid the long-term direct load operation of the pump, do not pump water with high sand content and observe whether the current value is within the value specified on the nameplate at any time. If the current is found to be too large, it should be stopped for inspection. In addition, the dehydration operation time of the electric pump should not be too long , so as not to overheat the motor and burn it.

9. Check frequently and find problems and fix them in time

Usually, the motor should be checked frequently. If cracks are found on the lower cover, or the rubber sealing ring is damaged or invalid, it should be replaced or repaired in time to prevent water from seeping into the submersible pump.

10. The rotation direction of the motor should be correct:

The rotation direction of the motor should be clarified. There are many types of submersible pumps that can discharge water when they are running forward and reverse, but the water output is small and the current is large when the reverse is reversed. If the reverse time is long, the motor winding will be damaged.
