Automatic control of hot air temperature in hot air circulation type enameled wire oven

摘要

The content of this study is to maintain the hot air temperature in the hot air circulation enamel steel wire oven for heat treatment of paint gasket, and to maintain a certain temperature regulating device.This is the engine overload caused by the old temperature regulating tool that manually adjusts the exhaust damping when the exhaust damping is fixed, when the exhaust fan rpm is adjusted or when the exhaust fan rpm is fixed,Reduced heater life,In order to solve the problem of temperature precision control, etc,Set the best range of the exhaust fan rpm, and adjust the hot air temperature of the RPM only within the set range,If it is out of the set range, the exhaust damper will be automatically activated to let the exhaust fan RPM return to the set range,In order to prevent the overload of fans and heaters, the hot air temperature in the oven can be effectively maintained and the product quality can be improved.
