Description

Technical Field

[0001] The utility model relates to the technical field of magnetic gear pumps, in particular to a magnetic gear pump which is easy to disassemble and clean inside. Background Art

[0002] A search revealed patent application number 201410323721.6, which discloses a magnetic gear pump. The present invention relates to a pump, particularly a novel magnetic gear pump designed to transport various chemical media, including oil, water, or toxic, hazardous, flammable, and explosive liquids. The pump is corrosion-resistant, acid- and alkali-resistant, high-temperature, and high-pressure-resistant, and features a magnetic drive, ensuring zero leakage and pulsation. The magnetic gear pump provided by the present invention addresses the shortcomings of current technology through innovative structural design, improved processing, and the rational selection of metal and non-metallic composite materials. This ensures the pump can operate under high-temperature, high-pressure, and various viscosity conditions, efficiently transporting toxic, hazardous, volatile, corrosive, and crystallizing media, as well as other harsh chemical media. Furthermore, the pump utilizes a magnetic drive to connect the motor drive, achieving zero leakage and pulsation, resolving the existing problem of shaft seal leakage, eliminating radial loads caused by misalignment, and providing overload protection. This makes it suitable for a wide range of applications in industries such as petroleum, chemical, pharmaceutical, food, tobacco, papermaking, and laboratories.

[0003] Currently, sanitary magnetic gear pumps used for food filling on the market are all sealed and have a locked screw structure. For food-grade fluids, prolonged operation can cause product contamination. Viscous substances such as milk can ferment inside the pump, causing mold and other health hazards. Cleaning the internal structure of the pump requires tools, which is very inconvenient. Using tools to disassemble and clean the pump can cause unstable operation and inaccurate accuracy.

[0004] Therefore, we propose a magnetic gear pump that is easy to disassemble and clean the interior. Utility Model Content

Example

[0024] A slot matching the specifications of the fisheye screw 9 is provided at the center of both side walls of the front end cover 14 .
