1. The inverter is used in the air conditioning load class
Office buildings, shopping malls and some supermarkets and factories have central air conditioning, and the electricity consumption of air conditioning is very large at the peak of electricity consumption in summer. In the hot climate, the electricity consumption of air conditioners in Beijing, Shanghai and Shenzhen accounts for more than 40% of the peak electricity. Therefore, using inverter equipment to drag the refrigeration pump, cold water pump and fan of the air conditioning system is a very good power-saving skill. At present, there are many companies specializing in short-term regulation of electricity in the country, during which the main skill is frequency conversion speed regulation and power saving.
2. The inverter is used in the crusher load
Metallurgical mines, building materials use a lot of crushers, ball mills, this kind of load after the selection of frequency conversion effect is significant.
3. The inverter is used in large kilns and calciners
Metallurgy, building materials, caustic soda and other large-scale industrial converter kilns (converters) used to use most of the DC, commutator motors, slip motors, cascade speed regulation or intermediate frequency unit speed regulation. Due to the fact that these speed regulation methods may have slip rings or low power, in recent years, many units have chosen frequency conversion control, which has an excellent effect.
4. The inverter is used in compressor loads
Compressors also fall under the widely used class of loads. Low-pressure compressors are widely used in various industrial sectors, and high-pressure large-capacity compressors are more used in steel (such as oxygen generators), mines, fertilizers, and ethylene. The selection of frequency conversion speed regulation brings the advantages of small starting current, power saving, and optimization of equipment service life.
5. The inverter is used in the rolling mill load
In the metallurgical profession, in the past, large-scale rolling mills used AC-AC frequency converters, and in recent years, AC-DC-AC frequency converters have been selected, and the communication of rolling mills has been a trend, especially in light load rolling mills, such as the multi-stand aluminum rolling mill of Ningxia National Aluminum Products Factory, which uses a universal frequency converter to satisfy the low-frequency load start, synchronous operation between the frames, constant tension control, and simple and reliable operation.
6. The inverter is used in the winch load
The winch load is selected for frequency conversion speed regulation, which is stable and reliable. The blast furnace winch equipment of the iron plant is the main equipment for transporting ironmaking materials. It requires stable start-up and braking, uniform acceleration and deceleration, and high reliability. Originally, the cascade, DC or rotor string resistance speed regulation method was mostly used, which had low power and poor reliability. Replacing the above-mentioned speed regulation method with a communication inverter can obtain the ideal effect.
7. The inverter is used in converter loads
For converter loads, the DC unit is replaced by AC frequency conversion, which is simple and reliable, and the operation is stable.
8. The inverter is used for roller table loads
Roller table loads, mostly in the iron and steel metallurgy occupation, the use of communication motor frequency control, can improve the reliability and stability of the equipment.
9. The inverter is used in pump loads
Pump load, large volume and wide area, including water pumps, oil pumps, chemical pumps, mud pumps, sand pumps, etc., there are low-pressure medium and small capacity pumps, as well as high-pressure and large-capacity pumps.
Many water supply companies' water pumps, chemical pumps, reciprocating pumps, non-ferrous metal and other occupations of the chemical pump, non-ferrous metal and other occupations use frequency conversion speed regulation, all of which have a very good effect.
10. The inverter is used in cranes and dump trucks
Cranes, dump trucks, etc. have large load torque and require stability, positive and negative frequency and require reliability. Inverter equipment can meet these requirements by operating cranes and dump trucks.
