Basic working principle

The intelligent silent pump is to assemble the submersible pump and the silent submersible motor in the pipeline, and fix it in the pipeline through a specific method to ensure that there will be no vibration during operation. The interior of the submersible motor is filled with landlord liquid to lubricate the bearings; the exterior is water-cooled, and after accurate calculation, it is ensured that the water flow inside the pipeline meets the requirements of cooling the motor and increases the service life of the submersible motor.

The principle of silent operation

On the basis of ordinary submersible pumps, our company has carried out many experiments and improvements on the mechanism and material of its key components, so that the noise can be further controlled. The improvement ensures the smooth operation of the motor and greatly reduces the noise; the middle of the motor and the cylinder is filled with liquid, which also plays a role in reducing noise; the structure of the whole machine is optimized, and the product is significantly improved in shock resistance and noise reduction.
