Application On Die Casting Machine Frequency Conversion Modification Of Plant

Firstly, according to the history, die casting machine’s working principle,analyses the working principle of variable frequency speed regulation. This paperdiscusses the application of current of variable frequency speed regulation device,structure characteristics of frequency converter focuses on rapid response in, andthe frequency of various well-known brands as an example, expounds theapplication of frequency converter and rapid response in the intermittent load.Then proceed from the running status of die casting machine, from thetheoretical analysis of the feasibility of the application of variable frequency speedcontrol technology in die casting machine. The frequency conversiontransformation of our company800tons die casting machine as an example,analyzes the concrete implementation method of frequency conversiontransformation projects and the implementation process. The special evaluation testof die casting machine of reconstruction, based on experimental data, a detailedanalysis of the security and economy of before and after the system transformation.The results show that the frequency converter has obvious energy saving effect, atthe same time running state of motor has been greatly improved, frequency controlscheme of the project is successful, and provides a reference example for otherprojects.
