Before the renovation, diamond frame saws usually operated at a constant frequency speed and could not be adjusted according to the texture and processing requirements of the stone. This leads to the possibility of the entire stone being shattered and causing economic losses if cracks or brittle stones are encountered during the processing process and the speed is not reduced. In addition, traditional frame sawing equipment cannot be smoothly adjusted, resulting in wavy patterns on the surface of the stone, which affects the processing quality.
The core of the renovation design lies in introducing frequency conversion technology, using ANYHZ brand FST-650L series frequency converters. By controlling with a frequency converter, the cutting speed can be adjusted according to the different characteristics of the stone, improving cutting quality and reducing stone loss. After the renovation, the equipment can achieve smooth adjustment of operating speed, extend the service life of the saw and reduce the frequency of maintenance and repair. In specific implementation, it is necessary to set the control parameters of the frequency converter based on the parameters of the motor and the on-site working conditions, such as acceleration time, deceleration time, frequency source, etc.
After the frequency conversion transformation, the benefits of the diamond frame saw are significant. Firstly, by using variable frequency speed regulation, it is possible to effectively avoid stone damage caused by excessive speed, reduce losses, and improve production efficiency. Secondly, smoothly adjusting the operating speed can improve the existing stone processing technology and extend the service life of the equipment. In addition, the application of frequency converters can reduce the impact on the power grid, lower energy consumption, and achieve energy-saving effects.
In the frequency conversion transformation of diamond frame saws, the following points should be noted:
1. There should be no reactive power compensation capacitor from the output terminal of the frequency converter to the motor to avoid affecting the normal operation of the frequency converter.
2. Due to the large periodic inertia of the equipment, it is necessary to install braking resistors (or energy feedback units) in actual use to avoid energy feedback problems caused by mechanical inertia.
3. During the debugging process, it is necessary to adjust the carrier frequency and motor tone according to the on-site conditions to adapt to the mechanical characteristics.
4. Stone equipment has periodic inertia during operation, so its current and DC bus voltage of the inverter fluctuate greatly. In application, the specifications of the inverter should be one level larger than the actual load.
The frequency conversion transformation of diamond frame saws is an important means to enhance the competitiveness of the stone processing industry. By introducing frequency converter technology, not only can cutting efficiency and quality be improved, but energy consumption and production costs can also be reduced. With the continuous advancement of technology and the deepening of applications, the frequency conversion transformation of diamond frame saws will bring greater development opportunities to the stone processing industry.
