Problems solved by technology

Since 2009, the inventor has successively obtained more than ten invention patents on permanent magnetic coupling speed regulators, and has built a factory with self-raised funds, forming mass production. Energy saving and emission reduction has been widely used and praised, which has greatly improved the level of energy saving technology. However, during the promotion process, it gradually realized that permanent magnetic coupling speed regulators have many advantages, but there are also the following shortcomings that are difficult to overcome: 1. Because the active and passive disks are air gap coupled cantilever beam structures, and are limited by the design of the axial installation size of the equipment, severe vibration and noise will inevitably occur under high power or / and high speed conditions, resulting in reliable system The second is that the system efficiency is low, especially under the conditions of low rated speed, high power, and more speed reduction, the energy proportional to the percentage of speed reduction will become a large amount of heat and be consumed in the metal conductor disk In fact, the average actual working total useful efficiency of the power load system is generally lower than 60%, especially for high-power models, because the system needs to add cooling devices, the cost will increase accordingly, and the reliability will also be greatly reduced; the third is It can only be adjusted by reducing the speed, but not by increasing the speed; fourth, the accuracy of speed adjustment is relatively low; fifth, there is no torque conversion or self-locking function between the active (power) shaft and the passive (load) shaft, so the application is greatly limited

[0003] High-voltage and high-power motor inverters also have many applications in the field of energy saving and emission reduction of centrifugal load systems. However, due to high requirements on the operating environment (constant temperature and humidity), they occupy a large space, have poor reliability, and consume a lot of energy; due to their working efficiency characteristics Constraints make the average actual total useful efficiency of the power load system in most frequency bands significantly lower than the rated efficiency, generally lower than 60%; the inverter will also produce serious power harmonic pollution, and the high-voltage inverter equipment is expensive, requiring There are many shortcomings such as dedicated maintenance and huge operating costs, which are also widely criticized

[0004] Hydraulic coupling governors are also widely configured in adjustable centrifugal load and non-centrifugal load systems (such as fans, water pumps, ball mills, feeders, conveyor belt conveyors, roadheaders, drilling machines, elevators, air compressors, etc.) , because the average actual working efficiency of the power load system is relatively low, and its speed regulation range is small, the consumption of hydraulic media consumables is large and the environment is polluted, etc., the technology is even more backward

[0005] For the traditional speed governor energy-saving technology mentioned above, on the one hand, it is only applicable to the "big horse-drawn trolley" system, which is not conducive to improving system efficiency and causing waste of resource allocation; During the adjustment process, only the power consumed by the load can be reduced, and the output efficiency of the power system cannot be improved. It will also cause the power system to greatly reduce the working efficiency, causing serious energy consumption and heat generation in the system. This heat is not only difficult to recycle, but also needs to be equipped with the system. Cooling device, while greatly increasing the cost input, the system reliability is also significantly reduced

In other words, for the current large-scale power load system, especially centrifugal equipment such as large fans and pumps, even if energy-saving equipment such as frequency converters, permanent magnet governors, and hydraulic couplings are installed, the average actual work of the power load system The total useful efficiency is generally not more than 65%, or even lower, and the waste is huge

In addition, due to the matching problem of power and load in the common power and load system, it will also cause serious energy or power waste.
