Application
1. Frequency converter is used in washing and ironing equipment load
The washing machine and ironing equipment of larger hotels used to adopt mechanical speed regulation or variable pole speed regulation, which can only provide one speed or several speeds, which is not ideal for fabrics that need to be repeatedly washed and ironed. Adopt frequency control, greatly improve the efficiency of washing machine.
2. Frequency converter is used in music fountain load
The musical fountain is very popular with visitors. Its water level and quantity are controlled by frequency conversion.
3. Frequency converter is used in grinder and other mechanical loads
The spindle of the grinder has a high speed, and the frequency of the power supply is also high, including 200Hz, 400Hz and even 800Hz. In the past, the main shaft motor was driven by the medium frequency generator set. Intermediate frequency unit has large volume, low efficiency, much noise and poor accuracy.
4. Frequency converter is used in cigarette machine load
Cigarette industry imported cigarette machines in the past, no matter Moline 8 or Moline 0, are not stepless speed regulation. Therefore, in the cigarette industry is mainly to solve the problem of stepless speed regulation and reliability, simple technology, simple frequency converter usage, great effect.
5. Frequency converter is used to reduce vibration and noise type load
Many loads, such as large air compressors and intermediate frequency units, have large noise and vibration. Using frequency conversion technology, vibration and noise reduction can be achieved within the standard.
6. Frequency converter is used in printing and dyeing machine load
Most printing and dyeing machines are multi-unit joint working equipment. The process requires each unit to run synchronously at the same linear speed and keep the tension constant, otherwise it will break cloth, wrap cloth, color imbalance, color degree is not enough, shrinkage rate is too high and other quality problems. The printing and dyeing machinery in the past adopts DC speed control system whether it is common power supply or sub-power supply.
Because of the inherent shortcomings of DC, the printing and dyeing industry gradually adopts AC frequency conversion technology. The rotary screen printing machine is composed of cloth feeding unit, printing unit, drying room guide unit and cloth dropping unit, which belongs to one of the complex printing and dyeing speed control system. Adopt frequency control to form speed chain control. Good synchronization performance, high precision, high reliability.
