There are several areas that the inverter can be applied to, do you know?
1. Air-conditioning load office buildings, shopping malls and some supermarkets and factories have central air-conditioning. In summer, the peak of electricity consumption, air-conditioning power consumption is very large. In the hot climate, the electricity consumption of air conditioners in Beijing, Shanghai and Shenzhen accounted for more than 40% of peak power. Therefore, using the frequency conversion equipment, dragging 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 air conditioning in the country. The first skill is frequency conversion and power saving. 2. Crusher load metallurgical mines, building materials use a lot of crushers, ball mills, the effect of this type of load after the use of frequency conversion is significant. 3. Large-scale industrial rotary kiln (converter) such as furnace calciner-loaded metallurgical large-scale kiln, building materials, caustic soda, etc. used to use DC, commutator motor, slip motor, cascade speed regulation or medium frequency unit speed regulation. Because these speed control methods either have slip rings or low power, in recent years, many units have used variable frequency control, and the effect is excellent. 4. Compressor-type load compressors also belong to a wide range of loads. Low-pressure compressors are used throughout the industrial sector. High-pressure large-capacity compressors are used in steel (such as oxygen generators), mines, fertilizers, and ethylene. The use of variable frequency speed control brings the advantages of small starting current, power saving, and optimized equipment service life. 5. Rolling mill load in metallurgical occupation. In the past, large-scale rolling mills used AC-AC inverters. In recent years, AC-DC-AC inverters have been used. Rolling mill communication has become a trend, especially in light-load mills. The multi-stand aluminum rolling mill of Ningxia National Aluminum Products Factory selects the general-purpose frequency converter, which is satisfied with the low-frequency load launching, synchronous operation between the racks, constant tension control, and simple and reliable operation. 6. The hoist type load hoist type load is selected by frequency conversion speed regulation, which is stable and reliable. The blast furnace hoisting equipment of the iron plant is the primary iron-conveying material conveying equipment. It requires smooth start and brake, uniform acceleration and deceleration, and high reliability. The original multi-stage, DC or rotor string resistance speed control method is adopted, and the power is low and the reliability is poor. By using a communication inverter instead of the above-mentioned speed control method, the desired effect can be obtained. 7. Converter type load converter type load, using communication frequency conversion instead of DC unit is simple and reliable, and the operation is stable. 8. Roller type load roller type load, mostly in steel metallurgy occupation, use communication motor frequency conversion control, can improve equipment reliability and stability. 9. Pump type load pump type load, wide range, including water pump, oil pump, chemical pump, mud pump, sand pump, etc., low pressure medium and small capacity pump, high pressure and large capacity pump. Many of the water pump, chemical and fertilizer professional chemical pumps, reciprocating pumps, non-ferrous metals and other professional mud pumps, such as the use of frequency control, have a very good effect. 10. Cranes, dump trucks, load cranes, dump trucks, etc. have large load torque and require stable, positive and negative frequency and require firmness. The inverter equipment and the dump truck can satisfy these requirements.
