Description

Technical Field

[0001] The utility model relates to the field of magnetic pumps, in particular to a rapid testing device for the isolation sleeve of a magnetic pump. Background Art

[0002] As a commonly used liquid transportation tool in the modern industrial field, the performance and safety of magnetic pumps have attracted much attention. Among them, the isolation sleeve of the magnetic pump, as one of the key components and main accessories, is mainly located between the rotating inner magnetic rotor and the outer magnetic rotor. The isolation sleeve is usually made of metal materials with strong corrosion resistance and high temperature resistance because of the limitations of the strength of the pump materials, processing technology, and usage conditions, etc.; to adapt to various liquid transportation environments, this design not only extends the service life of the magnetic pump but also reduces the maintenance cost. At the same time, it has the properties of corrosion resistance and high temperature resistance, can reduce the wear of the pump, improve the reliability of the pump, and is environmentally friendly and safe.

[0003] The isolation sleeve of the magnetic pump reliably prevents the direct contact between the liquid and the external environment by isolating the magnetic field. This electromagnetic isolation protection ensures that the magnetic force transmission system inside the pump is not interfered by external factors, improving the stability and safety of the pump. The isolation sleeve acts as a buffer and protection role during the operation of the magnetic pump, reducing the wear degree of the internal components of the pump. This helps to maintain the efficient operation state of the magnetic pump and slows down the aging speed of the equipment. By effectively isolating the liquid from the magnetic force transmission system, the isolation sleeve improves the reliability of the entire magnetic pump system. Even when the liquid medium changes or there are tiny particles, the core components of the pump can still be reliably protected, ensuring long-term safe operation. Using the isolation sleeve of the magnetic pump can effectively avoid leakage problems and reduce the potential hazards to the environment and operators during the liquid pumping process. Therefore, the isolation sleeve of the magnetic pump plays an important role in improving the stability and safety of the pump, which meets the strict requirements of modern industry for environmental protection and safety.

[0004] When selecting and using a magnetic pump, making reasonable use of the isolation sleeve will help improve the performance of the equipment and ensure the smooth progress of industrial production. Therefore, the role of testing qualified isolation sleeves is particularly important. However, the existing testing equipment requires frequent disassembly of a large number of workpieces to achieve the installation and disassembly of the isolation sleeve of the magnetic pump, resulting in low testing efficiency of the isolation sleeve of the magnetic pump and affecting the production efficiency.
