500 degree blast drying oven

500 degree blast drying ovenPrice,The hot air circulation industrial oven has reached the domestic and international level after multiple upgrades and replacements. The hot air circulation industrial oven is a substitute product with an average thermal efficiency of about 30%. It adopts a centrifugal fan, external circulation of the box, and manual temperature control. After multiple renovations, a hot air circulation industrial oven has been formed. This series of hot air circulation industrial ovens all use axial flow fans, are equipped with automatic constant temperature control systems, and have a computer control system for selection.

500 degree blast drying ovenPrice,The thermal efficiency is about 70%. The hot air circulation industrial oven uses steam or electricity as the heat source, and uses an axial flow fan to heat the air through convection heat exchange in the heat exchanger. The hot air flows laminar through the drying plate and transfers heat to the material. Fresh air is replenished from the air inlet, and waste humid and hot air is discharged from the dehumidification outlet, continuously replenishing fresh air and continuously discharging humid and hot air to maintain appropriate relative humidity in the industrial oven. The major feature of this series of industrial ovens is that some hot air circulates inside the oven, and the entire circulation process is enclosed, thereby enhancing heat transfer and saving energy.

Whether there are mechanical faults such as sweeping, vibration, bearing overheating, damage, loose fan blades, and cleaning of the casing. Specific situations can be excluded. Recheck if there are any local open circuits in the solid-state relay and heater. Solid State Relays (SSRs), abbreviated as' SSRs', are a new type of contactless switching device composed entirely of solid-state electronic components. They utilize the switching characteristics of electronic components such as switching transistors, bidirectional thyristors, and other semiconductor devices to achieve the purpose of connecting and disconnecting circuits without contact or spark. Therefore, they are also known as' contactless switches'.

SSR successfully achieved the control of weak signal (Vsr) over strong current (output load voltage). The partial open circuit caused by SSR virtual connection or conduction results in a phase loss of the 380V power supply, and the heater cannot be fully heated. The solution is to repair or replace the solid-state relay. The partial disconnection of the heater will also prevent the heating from working completely, resulting in a slow heating process. Repair or replace the heater. Resolve the fault issue properly. Close the air switch of the closed-loop industrial oven and run its program according to the operating instructions of the industrial oven. After 2.5 hours of heating, the industrial oven reaches the set temperature, and the time relay starts timing. The industrial oven enters the insulation stage of intermittent heating. After 1 hour of insulation, the industrial oven began to cool down. After 2.3 hours, the entire drying cycle program ended, meeting the technical and process parameter requirements provided by the industrial oven.
