Application field of micro DC water pump in kitchen and bathroom appliances industry

Now with the continuous improvement of living standards, people's demand for small household appliances is increasing. Running service adults need water pumps, and DC brushless water pumps are the most widely used water pumps in these small household appliances. Now let everyone understand how the water pump works.

Micro water pumps generally have 12V, 24V, 36V, 48V, etc. Micro water pumps are similar to other pumps. They are usually used to lift liquids, transport liquids or increase liquid pressure, that is, convert mechanical energy into liquid energy to achieve the purpose of pumping liquids, and The volume is very small, so they are collectively called miniature water pumps.

Micro DC brushless water pump refers to a machine that uses DC 4.5~24V to drive the brushless motor to run, and the rotation of the brushless motor drives the impeller to rotate, thereby increasing the hydraulic pressure of the liquid to achieve the function of transmitting liquid.

The working principle of the micro brushless DC water pump is through electronic commutation without using carbon brushes. The magnet rotor and stator silicon steel sheet have multi-level magnetic fields. When the magnet rotor rotates an angle relative to the stator, it will automatically change the direction of the magnetic poles, so that the rotor always Maintain the same level of repulsion, so that the brushless DC magnetic pump has a higher speed and efficiency.

The DC brushless water pump can work continuously and normally above 100 degrees. Can reach food grade. The field with the widest popularity and largest number. Mainly used in dishwashers, coffee machines, water dispensers, fruit juice machines, and other drinking water equipment.

Advantages of DC pumps

1. The pump shaft changes from a dynamic seal to a closed static seal, completely avoiding medium leakage. Can be used amphibiously and completely waterproof;

2. There is no need for independent lubrication and cooling water, which reduces energy consumption;

3. The power consumption is small, the efficiency is high, and it has the function of damping and vibration reduction, which reduces the influence of motor vibration on the pump and the influence of pump cavitation vibration on the motor.

4. When overloaded, the rotor will slip on the ceramic shaft, which has a protective effect on the motor and pump;

5. Adopt brushless motor, small size, meet food grade standard, long life, low power consumption, low noise;

6. It can be equipped with protection function and variable frequency.
