Information
Summary:
This article introduces an application case of an easy-drive ED3100 series inverter in coal washing machine. The coal washing machine can effectively extract clean coal from raw coal, coarse-washed raw coal, gangue, and gangue or sub-coal. The recovery rate is above 95%. The easy-to-drive ED3100 series inverter realizes its excellent reliability and stability. It meets the requirements of stepless speed regulation, buffer start and high quality of equipment.
I. Introduction
The coal washing machine can effectively remove gangue from raw coal, coarse washed raw coal, and extract clean coal from gangue or secondary coal. It can separate long flame coal, gas coal, fat coal, coking coal, lean coal, lean coal, etc. It is gray-black to black, with asphalt luster to diamond luster, and usually has a band-like structure without native humic acid. The volatile content is 10% to 40%, which generally decreases as the degree of coalification increases. The carbon content is 76% to 92%, the calorific value is high, and the calorific value is 2.71 to 37,200 joules/kg. Generally granular, small lumps, and powdery, mostly black and shiny, fine texture, containing more than 30% volatile content, not high ignition point, easy to ignite; high carbon content and calorific value, when burning The fire is fast, the flame is long, there is a lot of black smoke, and the burning time is long; most bituminous coal is sticky and easy to slag when burning. This article takes the easy-drive ED3100 series 15KW as an example to describe in detail the application of the easy-drive high-performance vector inverter in the coal washing machine
summary
Easydrive ED3100 series inverters have great cost-effective advantages in the coal industry due to their superior performance. The equipment fully combines the advantages of variable frequency stepless speed regulation, external terminal start, and convenient external ammeter. After the customer's use, the sorted and washed coal cinder meets the customer's product requirements, and all indicators meet the requirements. The simple operation, stability and reliability are highly recognized by users.
