Description

Technical Field

[0001] The utility model relates to the technical field of shielded pumps, in particular to a shielded pump with a heat exchanger. Background Art

[0002] The working principle of the shielded pump with heat exchanger is that the centrifugal force generated by the rotation of the shielded pump impeller sucks the liquid or medium into the heat exchanger part. In the heat exchanger, these liquids or media will exchange heat with another fluid to achieve the effect of heating or cooling.

[0003] In the existing technology, the shielded pump is composed of a pump body, an impeller, an electric motor, and a heat exchanger. The pump body is the main part of the shielded pump, and the impeller is installed on the rotor shaft of the electric motor. When the motor is started, the rotor shaft drives the impeller to rotate to generate centrifugal force, so that the liquid flows in the pump body and is transported to the outlet. The cooling medium of the heat exchanger (such as water, oil, etc.) is used to cool or heat the liquid in the pump body to change the temperature of the liquid. However, in actual use, when the device passes through the heat exchanger, the internal fluid of the heat exchange box performs heat exchange, and water inlet pipes and water outlet pipes are provided on both sides to make the internal fluid flow. During the flow of the fluid, since the fluid is in the heat exchange box, the internal fluidity is poor, which may lead to the inability to absorb the heat or heat of the liquid passing through the heat exchanger in time, resulting in poor overall conversion efficiency of the device, which further makes the use effect of the device poor. Therefore, it is necessary to improve a shielded pump with a heat exchanger. Utility Model Content
