When the production process requires adjustment of the process parameters, the flow rate can only be changed by increasing (reducing) the system resistance method, and the motor is always running under the rated operating conditions, resulting in waste of electrical energy.
The frequency conversion energy-saving is mainly used in applications where the change of rotational speed of the AC motor is required to change the driving mechanical characteristics to meet the production process requirements, and it is mostly applied to fans and pumps. When the motor can only be operated at rated speed, its drive machinery can only operate at a certain rated speed. With the continuous improvement of industrial automation, inverters have also been widely used. Energy-saving and environmental protection are the core of China's industrial economic development. While pointing the direction for the sustainable development of China's industry, they are also effectively stimulating the drive industry in China. The sustainable development of China's inverter industry has continuously expanded the market share of the industry, and has become an important starting point for the development of China's industrial economy with strong development. The frequency conversion energy-saving is mainly used in applications where the change of rotational speed of the AC motor is required to change the driving mechanical characteristics to meet the production process requirements, and it is mostly applied to fans and pumps. When the motor can only be operated at rated speed, its drive machinery can only operate at a certain rated speed.
When the production process requires adjustment of the process parameters, the flow rate can only be changed by increasing (reducing) the system resistance method, and the motor is always running under the rated operating conditions, resulting in waste of electrical energy. For example, the conventional speed regulation method for fans, pumps and other equipment is to adjust the amount of air supply and water supply by adjusting the baffle and valve opening of the outlet (or inlet). In addition to the power consumption, the system accessories are also increased, and the number of The probability of system failure. When using variable frequency speed regulation, if the flow requirements are reduced, the requirements can be met by reducing the pump or fan speed. In a comprehensive view, the inverter mainly achieves energy-saving effects through power factor compensation and soft-start. In terms of power factor compensation, the reactive power will increase the line loss and heat of the equipment. In addition, the reduction of the power factor leads to the reduction of the active power of the power grid. Among the large number of reactive power consumption lines, the equipment is inefficient and wastes. After the frequency converter is used, the internal filter capacitor of the inverter acts to reduce the reactive power loss and increase the active power of the power grid.
In terms of soft start energy saving, the hard start of the motor will cause serious impact on the power grid, and at the same time, the requirement for the power grid capacity is also too high. When the large current and vibration are generated during startup, the damage to the baffle and the valve is extremely great. The use of the equipment and pipelines is great. Life is extremely unfavorable. The use of the soft-start function of the inverter will start the starting current from zero, reduce the impact on the grid and the requirements for the power supply capacity, extend the service life of the equipment and valves, and thus save the maintenance cost of the equipment. However, it should be noted that the problem of small carts should be avoided in the use of inverters. The reason for this problem is based on the limitations of the working conditions at the time of the design being put into operation, so that the design and installation save money. In many places, the frequency conversion power is less than the rated power of the motor. However, with the development of technology and the change of production conditions, the problem of small horse-drawn carts inevitably arises, causing the inverter to fail to operate normally. Therefore, in the trial period of the frequency conversion device, in order to prevent problems, detection and adjustment should be conducted in advance to avoid the above problems. In addition, after 6 years to 10 years of normal use of the inverter, it is easy to enter the high failure period. Faults such as burn-out of components, frequent failures, and frequent actions of protection functions often occur, which seriously affect normal operation.
