[0002] A magnetic pump is a leak-free, reliably sealed water pump that transmits power through magnetic force. It is widely used in the fields of petroleum, chemical industry, metallurgy, electricity, aerospace, environmental protection and water treatment. However, after long-term use, the parts connected to the external pipe of the traditional magnetic pump are exposed for a long time and corroded by corrosive liquids for a long time, which is prone to corrosion, which is not conducive to later use and maintenance and affects work efficiency. Therefore, we designed a corrosion-resistant magnetic pump.

[0003] Patent No. CN202221892345.9 is a Chinese utility model patent, which discloses a long-term use type corrosion-resistant magnetic pump, which solves the problem of easy corrosion at the interface, including a magnetic pump body, the front surface of the magnetic pump body is provided with a front panel, the outer surface of the front panel is connected with a connecting component, the front panel is connected with a protective component through the connecting component, the protective component includes a ring plate that fits the outer surface of the front panel, and the outer surface of the ring plate is provided with a connecting hole. The utility model can prevent the magnetic pump from being connected to the pipe body during long-term use through the designed connecting component and protective component. The interface is easily exposed, and at the same time it can prevent external corrosive liquids or fluids from eroding the interface, effectively provide anti-corrosion protection for the interface, avoid some problems caused by liquid corrosion at the interface, and the connecting component can provide a stable connection fulcrum for the protective component, which can be quickly disassembled and fixed. However, the utility model has the following problems: First, a large number of bolts are used to connect the front panel and the connecting component and the protective component in the utility model. The large number of bolts reduces the speed of production and assembly and increases production costs. Secondly, the sealing effect between the front panel and the protective part in the utility model is poor, which is prone to leakage of the transported liquid. Utility Model Content
