How does a canned motor dissipate heat?

 In fact, there is a small gap between the rotor and the stator in the pump, so that the liquid flowing in the pump flows through and takes away the heat of the motor. The motor and the pump of the canned pump are connected together and sealed in a container filled with the pumping medium. Its sealed and safe characteristics are widely used to transmit highly corrosive, flammable, explosive or toxic gases. In recent years, canned pumps The effect of its use is more and more recognized and accepted by people.
       Canned pump can be used in particularly harsh environments, such as petroleum, chemical, environmental protection, high temperature hot water circulation system environment. Due to the special nature of the pumping medium, the stator and rotor in the pump must be equipped with shielding sleeves to ensure that they are not Eroded. Extend the life of canned pumps.
       Due to the sealing requirements of the canned pump, the material requirements for its production are also particularly high. Generally, stainless steel with high corrosion resistance is used. Welding is performed using special welding equipment. After welding is completed, helium gas is also required to test for leaks and ensure its Tightness.
       Bearings in canned pumps are subject to frictional damage due to constant rotation during work. Therefore, the materials used to make bearings in pumps need to be corrosion-resistant and friction-resistant, such as lcr18Ni9Ti stainless steel. In the manufacturing process, you can choose to dip the epoxy resin treatment, which can ensure higher heat resistance and lower friction coefficient.
