What are the applications of Yaskawa inverter?

1. Compressor load

Compressors are also widely used loads. Low-pressure compressors are widely used in various industrial sectors, and high-pressure large-capacity compressors are widely used in steel (such as oxygen generators), mines, fertilizers, and ethylene. The use of frequency conversion speed regulation brings the advantages of small starting current, power saving, and optimization of equipment service life. Also pay attention to the maintenance of Yaskawa inverter.

2. Mill load

In the metallurgical industry, in the past, large-scale rolling mills were multi-purpose AC-AC frequency converters, and in recent years, AC-DC-AC frequency converters have been used in rolling mills, especially in light load rolling mills, such as the multi-stand aluminum rolling mill of Ningxia National Aluminum Products Factory adopts universal frequency converter to meet the needs of low-frequency load starting, synchronous operation between stands, constant tension control, and simple and reliable operation.

3. Winch class load

The winch load adopts frequency conversion speed regulation, which is stable and reliable. The blast furnace winch equipment of the iron plant is the main equipment for conveying raw materials for ironmaking. It requires stable start-up and braking, uniform acceleration and deceleration, and high reliability. Originally, cascade, DC or rotor string resistance speed regulation methods were mostly used, which had low efficiency and poor reliability. It should be noted that the AC inverter for the maintenance of Yaskawa inverter can replace the above-mentioned speed regulation method, which can achieve ideal results.

4. Crusher load

Metallurgical mines, building materials use many crushers, ball mills, this kind of load after the use of frequency conversion effect is significant.

5. Large-scale kiln calciner load

In the past, most of the large-scale industrial converters (converters) such as metallurgy, building materials, and caustic soda used to use DC and 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 efficiency, in recent years, many units have adopted frequency conversion control, and the effect is excellent.

6. Converter load

For converter loads, replacing DC units with AC frequency conversion is simple and reliable, and the operation is stable.

7. Roller table load

Roller table loads, mostly in the iron and steel metallurgy industry, the use of AC motor frequency conversion control, pay attention to the maintenance of Yaskawa frequency converter can improve the reliability and stability of the equipment.

8. Pump load

Pump load, large volume and wide range, including water pumps, oil pumps, chemical pumps, mud pumps, sand pumps, etc., there are low-pressure small and medium-capacity pumps, as well as high-pressure large-capacity pumps.

Many water supply companies' water pumps, chemical pumps, reciprocating pumps, non-ferrous metal and other industries use frequency conversion speed regulation, all of which produce very good results.

9. Cranes, dump trucks

Cranes, dump trucks, etc. have large load torques and require stability, and positive and negative are frequent and reliable. Inverter-controlled cranes and dump trucks can meet these requirements.

10. Wire drawing machine load

Wire drawing machines for the production of steel wires require high-speed and continuous production. The strength of the steel wire is 200Kg/mm, and the speed control system requires high precision, high stability and synchronization.

11. Transporting vehicle loads

The raw coal loading vehicle of the coal mine or the molten steel delivery vehicle of the steel mill adopts frequency conversion technology, which works very well. Fast start and stop, strong overload capacity, flexible forward and reverse rotation, to achieve a smooth coal surface, correct weight (no more or less installation), basically do not need manual operation, pay attention to the maintenance of Yaskawa inverter to improve the production efficiency of raw coal, save electric energy.

12. Elevator elevated tour car class load

Because the elevator is a manned tool, the drag system is required to be highly reliable, and it is necessary to frequently accelerate and decelerate and rotate forward and reverse, and the improvement of the dynamic characteristics and reliability of the elevator increases the sense of safety, comfort and efficiency of the elevator ride. In the past, the elevator speed regulation was mostly DC, and in recent years, it has gradually switched to AC motor frequency conversion speed regulation, whether in Japan or Germany. Many elevator factories in China are scrambling to use frequency conversion speed regulation to equip elevators. For example, Shanghai Mitsubishi, Guangzhou Hitachi, Qingdao Fuji, Tianjin Otis, etc. all use AC frequency conversion speed regulation. Many of the original elevators have also been transformed into frequency converters.

13. Feeder class load

Metallurgy, electric power, coal, chemical and other industries, there are many feeders, whether it is a disc feeder or a vibrating feeder, the effect of frequency conversion speed regulation is very significant. The disc feeder of the sulfuric acid production line of the dye factory of Jihua Company was originally a slip speed regulation, with small low-frequency torque, many faults and frequent jamming. After the use of frequency conversion speed regulation, because it is an asynchronous machine, high reliability, power saving, and more importantly, the closed-loop temperature transmitter ensures the accuracy of the conveyed materials, and it is necessary to pay attention to the maintenance of the Yaskawa inverter so as not to cause accidents due to excessive oxidant delivery and overtemperature, so as to ensure the orderliness of production.

14. Stacker and reclaimer load

The stacker-reclaimer is the main equipment for stacking materials in coal yards, wharves and mines, and its main function is to pile and reclaim. Realize automatic stacking and semi-automatic reclaiming, improve the reliability of the equipment, the equipment runs smoothly, there is no impact and shaking phenomenon, the reclaiming process is rotated according to the 1/cosφ rule, which improves the efficiency of the bucket wheel rotary reclaiming and the uniformity of belt coal transportation, which is very popular with workers.

15. Fan load

Fan load is a large amount of equipment, steel mills, power plants, nonferrous metals, mining, chemical industry, textile, chemical fiber, cement, papermaking and other industries are more used. Most of them use the adjustment baffle opening to adjust the air volume, which wastes a lot of electric energy, and the use of frequency conversion speed regulation can save power and reduce mechanical wear and extend the life of the equipment.
