[0025] like Figures 1-5As shown, this embodiment provides a high-temperature resistant, jacketed, insulated magnetic pump, including a magnetic pump body 1. The magnetic pump body 1 consists of a pump body 24 and a mounting mechanism 11. The bottom of the pump body 24 is mounted on the upper side of the mounting mechanism 11. A control processor 8 is mounted in the middle of the front end of the mounting mechanism 11. A wireless transceiver module 10 is mounted below the front end of the control processor 8.

Preferably, the heat preservation mechanism 7 consists of a housing 12, an inlet pipe 25, and an outlet pipe 26. The housing 12 is mounted outside the pump casing 16, the inlet pipe 25 is mounted at the bottom right side of the housing 12, and the outlet pipe 26 is mounted at the upper right side of the housing 12. The insulation mechanism 7 consists of a housing 12, an inlet pipe 25, and an outlet pipe 26. The housing 12 is wrapped around the outside of the pump housing 16. The inlet pipe 25 is installed at the bottom right side of the housing 12, and the outlet pipe 26 is installed at the top right side of the housing 12. During operation, the insulation medium, such as hot water or heat transfer oil, flows into the interlayer between the housing 12 and the pump housing 16 through the inlet pipe 25, forming a circulation channel, and then flows out through the outlet pipe 26, continuously providing temperature protection for the pump housing 16 and the liquid transported inside.

The advantages are that the welding fixing method is stable and reliable, the heat-conducting plate can enhance the heat transfer efficiency, which not only helps to improve the heat preservation effect, but also plays a certain role in heat dissipation protection, extends the service life of the pump casing 16, and meets the requirements of high temperature resistance design.

[0027] Preferably, a first heat-conducting plate 15 is installed on the outer side of the mounting cylinder 14, and the first heat-conducting plate 15 is welded to the outer side of the mounting cylinder 14. The first heat-conducting plate 15 can conduct heat from the surface of the mounting cylinder 14, avoiding local heat accumulation in the mounting cylinder 14. In particular, it can be combined with the overall heat insulation design to reduce heat diffusion to the magnetic drive area. Its advantages are simple structure, rapid heat conduction, and it can help ensure the temperature stability of the mounting cylinder 14 and surrounding components, prevent high temperature from affecting the equipment connection structure or magnetic coupling effect, and further improve the high temperature resistance of the equipment.

The rubber damping plate 6 is installed at the bottom of the installation plate 2, and the bottom of the rubber damping plate 6 is installed on the upper side of the fixing plate 5. The fixing plate 5 provides a stable installation foundation, the installation plate 2 bears the weight of the magnetic pump body 1, and the rubber damping plate 6 absorbs the vibration energy generated during equipment operation through its own elastic deformation, weakening the impact of vibration on the pump body 24 and the installation foundation. The advantages are that the vibration reduction effect is significant, which can reduce the operating noise of the equipment, reduce the loosening or wear of parts caused by vibration, improve the operating stability and service life of the equipment, and simplify the installation process and enhance the adaptability of the equipment under different working conditions.

[0029] Preferably, the environmental detector 23 consists of a temperature sensor and a vibration sensor. During operation, the temperature sensor collects real-time temperature data of the area surrounding the pump body 24 and the medium, while the vibration sensor monitors the amplitude and frequency of vibration during equipment operation. Both types of data are transmitted to the control processor 8 for analysis and processing. The advantage is that it can comprehensively capture key environmental parameters of equipment operation, promptly detect problems such as abnormal temperature rise and excessive vibration, provide data support for subsequent alarm prompts and fault diagnosis, improve the safety and reliability of equipment operation, and adapt to the design requirements of strong magnetic resistance and high temperature.

[0030] Preferably, a display 9 is mounted on the upper left side of the control processor 8, and control buttons 4 are mounted on the upper right side of the control processor 8. During operation, the display 9 shows the temperature and vibration data collected by the environmental detector 23 in real time, as well as the equipment operating status such as start / stop and insulation medium circulation. The control buttons 4 can be used to manually set operating parameters such as insulation temperature range, alarm threshold, and start / stop the equipment. The advantages are that the visual display interface allows operators to intuitively grasp the equipment status, and the manual control buttons 4 are convenient and flexible, allowing for quick adjustment of operating parameters to adapt to different work needs. Combined with the core control functions of the control processor 8, the ease of operation and intelligence of the equipment are further improved.

[0031] Work steps

[0032] During operation, after the motor 22 starts, it drives the outer magnet 20 to rotate. Through magnetic coupling, the magnetic lines of force generated by the outer magnet 20 penetrate the isolation sleeve 13, driving the inner magnet 19 to rotate synchronously. The inner magnet 19 then links the pump shaft 18 and the turbine 21 inside the pump body 24 to form rotational power. The negative pressure suction generated by the rotation of the turbine 21 draws in the liquid to be transported, and after pressurization, it is transported stably. At the same time, the extended pump shaft 18, together with the isolation sleeve 13, heat insulation piles 27 and heat insulation sleeves 28, constructs a double heat insulation barrier, effectively preventing the heat of the transported medium or the external environment from being transferred to the magnetic drive area. To prevent magnetic attenuation or component damage caused by high temperatures, the environmental detector 23 collects key operating data such as temperature and vibration in real time during the process and transmits it synchronously to the control processor 8 for analysis and processing. The control processor 8 realizes remote data interaction through the wireless transceiver module 10. If abnormal parameters are detected, the alarm 3 will be triggered immediately to issue a reminder. The entire operation relies on a contactless magnetic transmission structure to eliminate the risk of leakage from the source. Combined with comprehensive heat insulation protection and intelligent monitoring mechanisms, it not only ensures the conveying efficiency under high-temperature conditions, but also improves the safety and ease of operation of the equipment.
