Self-water-cooled energy-saving motor for centrifugal pump

Abstract

The invention discloses a self-water-cooled energy-saving motor for a centrifugal pump. The energy-saving motor comprises a base. A bottom plate is fixedly connected with the upper surface of the basethrough a bolt. A motor body is fixedly mounted on the upper surface of the bottom plate. A pump body is further fixedly mounted on the upper surface of the base and located on the right side of thebottom plate. The pump body comprises a pump cover. A groove is formed in the pump cover. A mechanical seal is fixedly mounted in the groove. A rotary shaft is fixedly sleeved with the interior of themechanical seal. The right end face of the mechanical seal is attached to the inner bottom wall of the groove. The right end of the rotary shaft penetrates through the pump cover and extends to the right side of the pump cover. According to the self-water-cooled energy-saving motor, by winding a heat exchange pipe on the outer surface of the motor body, water extracted into the pump body during operation of the centrifugal pump can flow through the heat exchange pipe and absorbs heat generated by the motor during operation, the working temperature of the motor is lowered, the energy consumption of the motor is reduced, the radiating effect is good, and the energy conservation effect is achieved.

Description

technical field [0001] The invention relates to the technical field of energy-saving motors, in particular to an energy-saving motor for a self-water-cooled centrifugal pump. Background technique [0002] A centrifugal pump refers to a pump that delivers liquid by the centrifugal force generated when the impeller rotates. The centrifugal pump uses the impeller to rotate to make the water centrifugally move to work. Before the pump starts, the pump casing and the suction pipe must be filled with water, and then started. The motor drives the pump shaft to drive the impeller and the water to rotate at high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller, and flows into the pressure water pipeline of the pump through the flow channel of the volute pump casing. The centrifugal pump is mainly composed of a pump body and a motor. . [0003] The motor in the centrifugal pump will generate a lot of heat when it works for a long time. The...
