Description
Technical Field
The invention relates to a pump, in particular to a high-temperature magnetic pump.
Background
The magnetic pump is a common fluid conveying machine, and is widely applied to the industries of medicine, chemical industry, bathroom and the like due to the advantages of no leakage, low noise, stable operation and the like. The magnetic pump comprises a shell, an impeller, a pump cover, a pump shaft, an inner magnetic rotor, an isolation sleeve, an outer magnetic rotor, a motor and a lining plate positioned at the end part of the motor, wherein the outer magnetic rotor is fixedly connected with the motor shaft, the inner magnetic rotor is fixedly connected with the pump shaft, the isolation sleeve consists of a flange, a thin-walled cylinder and a bottom plate, the flange of the isolation sleeve is connected with the pump cover, the motor drives the outer magnetic rotor to rotate and then drives the inner magnetic rotor to rotate, and the inner magnetic rotor is a driven part. When the magnetic pump is used in a high-temperature environment, heat is transferred to the motor due to the fact that the conveying medium has the higher temperature, and the motor has the thermal protector, so that the utilization rate of the magnetic pump is reduced, and the use cost of a user is higher.
Disclosure of Invention
