Description

Technical Field

[0001] The utility model relates to the field of magnetic pumps, in particular to a magnetic pump with a cooling function. Background Art

[0002] The magnetic pump consists of three parts: a pump, an electric motor, and a magnetic transmission. The key component, the magnetic transmission, consists of an outer magnetic rotor, an inner magnetic rotor, and a non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic materials, driving the inner magnetic rotor connected to the impeller to rotate synchronously, realizing contactless power transmission and converting the dynamic seal into a static seal. However, a large amount of heat is generated when the device is used as a whole. The commonly used magnetic pump lacks effective heat dissipation components, resulting in limited heat dissipation effect of the magnetic pump. After working for a long time, the device is prone to overheating and damage.

[0003] The existing patent discloses "a magnetic pump with a cooling function", including a base, a bracket is provided at the upper end of the base, a pump body is provided on the upper end surface of the bracket, a water inlet pipe is penetrated through the right end surface of the pump body, a water outlet pipe is penetrated through the upper end surface of the pump body, a baffle is provided inside the pump body, a transmission shaft is rotatably provided on the baffle, an impeller is provided on the left side of the outer end surface of the transmission shaft, and multiple impellers are provided in the circumferential direction of the impeller, an inner magnetic rotor is provided on the transmission shaft, a drive shaft is rotatably provided at the left end of the pump body, an outer magnetic rotor is provided on the right side of the outer end surface of the drive shaft, a drive motor is connected to the left end of the drive shaft, an isolation sleeve is provided between the outer magnetic rotor and the inner magnetic rotor, the isolation sleeve is fixedly mounted on the baffle, a shell is provided on the outside of the pump body, the shell is detachably provided on the upper end of the base, a cooling water pipe is detachably provided inside the shell, and a water supply pipe and a water return pipe are respectively connected to the left and right sides of the cooling water pipe. In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. In the above-mentioned device, the first heat dissipation fins and the second heat dissipation fins dissipate heat for the heat dissipation component after absorbing the heat of the magnetic pump. The first heat dissipation fins and the second heat dissipation fins in the device are in the external environment, and the industrial and chemical industries are one of the most widely used fields for magnetic pumps. The air in the working environment of the magnetic pump is dusty, and the dust accumulates on the surface of the heat dissipation fins, which will reduce the heat dissipation efficiency of the heat dissipation fins; 2. The first heat dissipation fins and the second heat dissipation fins in the above-mentioned device use natural airflow for cooling, so that the heat dissipation efficiency of the heat dissipation device is limited after absorbing the heat of the magnetic pump.
