Industrial hot air blower works
Author： Date：2013-1-26 16:31:01
Energized, the blower blowing air to the heater, so that air from the electric wire of the spiral, the outer evenly through the heat generated in the electric wire is energized with the cool air through the heat exchange, thereby the outlet of the air temperature increased. The outlet at the K-type thermocouple timely feedback to the outlet air temperature probe to the temperature control device, instrument monitoring the actual temperature of the work according to the set temperature, and the information is passed back to the solid state relay and then control the heater is job. At the same time, the fan air volume control (inverter, throttle) to adjust the size of the amount of wind blowing the air.2080 non-magnetic nickel-chromium wire ohmic heating air for hot air source, clean, environmentally friendly.
Built-in anti-dry unit.
Clever wind tunnel design, the air from the spiral heating wire within / outside evenly through the heat exchange nearly 100%, less pressure loss.
This picture is taken from Huawei electromechanical
Microcomputer PID / SSR control, high precision, fast feedback, durable.
Has multiple thermal overload protection device, fully ensure the safety of the equipment can be running non-stop work 365 days a year.
Outlet with a K-type thermocouple, direct detection and control, air outlet temperature constant.
Fiber cotton insulation insulation, sturdy chassis, the use of safe and reliable.
Continuous use temperatures up to 350 ° C, a wide range of applications.
Circulating hot air blower applications patent heat sink design, continuing up to 230 ° C inlet air temperature, air volume control inverter is used, more energy-efficient, high controllability, less heat loss and other outstanding features.
The standard hot air blower uses the international brand main electrical control (such as an inverter, PID temperature controller, SSR, circuit breakers, intermediate relays, magnetic switches, etc.); PID thermostat accuracy of ± 0.1%, and is equipped with a remote switch .
Cheap hot air blower the international brand main electrical controls (such as PID temperature controller, SSR, circuit breakers, intermediate relays, magnetic switches, etc.), do not deserve the inverter, PID temperature controller with motor protection; accuracy ± 0.1%.
In addition, the development and application of heated part of the addition to the nickel-chromium wire Yiyin different environment Use a stainless steel heat pipe, iron-chromium heating wire and infrared heating tube, and in addition to the K-type temperature sensing element thermocouple, also with E-type thermocouple and Pt100 RTD.
As for the fan part, the better the motor insulation class F or more aluminum motors need enough material and lead to heavier, more built-into the wind current over-temperature (generally due to overrun or the environment caused by temperature) protection device.
The control circuit part, in addition to the performance and accuracy of the control elements on the line more automatic protection function (such as heating core over-temperature and over-current protection, motor over-temperature and over-current protection, environmental over-temperature protection, dumping protection, the wind overtemperature alarm, etc.) as possible. Able alarm signal is sent to the PLC's better.
