Abstract
The utility model discloses a special pump for a sedimentation tank, comprising a pump body. The two sides of the pump body are respectively provided with a liquid inlet and a liquid outlet. The upper end of the pump body is fixedly connected with a motor. The lower end of an output shaft of the motor is fixedly connected with an impeller. An upper water storage chamber and a lower water storage chamber are arranged within the pump body. The liquid outlet and the liquid inlet are respectively communicated with the upper water storage chamber and the lower water storage chamber. A check valve is serially connected to the liquid outlet and the liquid inlet. The lower end of the shaft is provided with a stirring wheel for stirring sediments in the pump. The surfaces of the water storage chamber, the liquid inlet, the liquid outlet and the check valve, through which media pass, are provided with High Velocity Oxygen Flame (HVOF) nano-coatings. The pump has good wear resistance, corrosion resistance and erosion resistance. Simultaneously, strong impact generated by HVOF causes the coatings in a compressive stress state, so coating cracks are reduced, and the coatings form a super wear-resistant protective layer. The pump belongs to a seal-less self-control self-priming pump technology, and is suitable for the sedimentation tank.
