At present, engraving machines have gradually become an essential professional tool for production in various industries. With the development and application of CNC numerical control technology combined with high-performance inverter controllers and servo drive equipment in various production industries, CNC engraving machines have increasingly become the mainstream configuration of the engraving industry today. . Most of the main drive systems of CNC engraving machine tools use infinitely variable speed. Inorganic variable speed systems mainly include frequency conversion spindle system and servo spindle system. Due to the high cost performance of frequency converters, frequency converters are widely used in machine tools. The spindle system is an important component of the CNC engraving machine, and its performance has a crucial impact on the performance of the CNC engraving machine. As the heart of the spindle system, the frequency converter is an indispensable key component. The following introduces the application of Dolycon CT100E Variable Frequency Drive in the spindle drag system of CNC engraving machine. Introduction to the control principle of CNC engraving machine CNC engraving machine control system composition The CNC engraving machine control system is mainly composed of three parts: CNC numerical control system, spindle positioning system and spindle rotation system. The functions of each part are as follows: CNC numerical control system: The design and typesetting are carried out through the special engraving software configured in the computer, and the information of design and typesetting is transmitted to the controller of the engraving machine through the computer, and then the controller converts the information into a stepper motor or servo drive. The pulse signal of the motor, the positioning system completes the design and layout pattern model by receiving the pulse signal to complete the positioning. Servo positioning system: The three-axis positioning can be completed by using three axes that are perpendicular to each other in the three-dimensional space. Therefore, the three sets of servo positioning systems respectively receive the pulse signals from the CNC numerical control system to carry out the engraving and positioning of the X, Y, and Z axes. , you can complete any pattern model in three-dimensional space. Spindle processing system: The servo positioning system completes the pattern and model setting, and the corresponding engraving work needs to be completed at the corresponding fixed-sample position to complete the engraving items typed by the CNC numerical control system. Therefore, the high-speed rotation of the spindle is required to complete the engraving work. Different engraving materials and differentiated engraving precision also require the rotating system to have a flexible speed regulation function. The control requirements of the spindle processing system of the engraving machine to the frequency ...

Traditional industrial washing machines use multiple two-speed AC motors for speed regulation, which are widely used due to their simple structure, firmness, and low price. But its disadvantage is that the speed regulation performance is poor, the speed change is large, and the vibration is large. With the development of power semiconductor technology, in recent years, AC variable frequency governors have become more popular in industrial washing machines. Industrial washing machines have higher and higher requirements for inverters, and they are required to meet the requirements of industrial washing machines. High starting torque, multi-stage speed , wide voltage range, automatic slip compensation and fast and powerful communication methods and other technical difficulties. And stable performance, can adapt to a variety of complex high temperature, high humidity environment. How industrial washing machines work CNC engraving machine control system composition Fully automatic industrial washing machine refers to a large-capacity washing machine that has functions such as initial washing, washing, rinsing, bleaching and dehydration, and can realize automatic conversion without manual operation between functions. The industrial washing machine is mainly composed of the outer cylinder, the rotating cylinder, the transmission part, the electrical control cabinet, the left and right sealing covers, the pipeline instruments and the drain valve.

This article mainly describes the application of ct100 series frequency converter in high frequency ozone generator of Shenzhen Dolycon Technology Co., Ltd. the power supply system realized by ct100 frequency converter ensures the stability and reliability of ozone generator system. Ozone is a strong oxidant, which is widely used in drinking water, sewage, industrial oxidation, food processing and preservation, pharmaceutical synthesis, space sterilization and other fields. Since ozone will fission into completely harmless oxygen atoms after acting on microorganisms, it will never produce secondary pollution. Therefore, ozone has been used more and more to replace the disinfection of chlorine and its compounds. Ozone has been recognized as the best disinfectant for environmental protection. The power frequency power supply is used in the traditional ozone generation scheme, but the power frequency generator is large in volume and high in power consumption, and has been basically withdrawn from the market. The medium and high frequency generators have the advantages of small size, low power consumption and large ozone production, which are the most commonly used products now. This paper introduces the application of ct100 series frequency converter developed by Shenzhen Dolycon Technology Co., Ltd. in high-frequency ozone generator, taking the inverter matching touch screen of a Beijing ozone generator company as an example. Principle of high frequency ozone generator Principle of ozone generation The industrial production method of ozone usually uses the principle of high-voltage silent discharge: let the purified dry air or oxygen flow through the electrode gap. Through the high-voltage discharge gap, some oxygen molecules are broken and the chemical bond is broken to generate oxygen atoms. The oxygen atoms and oxygen molecules combine to form ozone. This method of ozone generation is called corona discharge, that is, when the high-frequency sinusoidal AC voltage between the two electrodes of the discharge device is greater than the critical corona inception voltage, corona discharge is generated on the surface of the discharge electrode. The instability of ozone makes it difficult to realize bottled storage. Generally, ozone generator can only be used for on-site production, which requires that the output of ozone can be automatically adjusted according to actual needs, but the gas production efficiency should not be reduced. System structure of high frequency ozone generator The main structure of high frequency ozone generator is divided into four parts 1. Power supply part: the core control part is composed of high frequency output frequency converter and step-up transformer. The high-frequency output converter transforms the power frequency power supply into the high-frequency output above 8kHz, which has provided high-frequency power supply; The step-up transformer transforms the high-frequency power supply provided by the frequency convert...
