Each air knife system is specially designed to meet project requirements while reducing energy consumption or reducing compressed air. Usually air knife systems generally provide ROI in 6 months.
Blowers are maintained for several years through regular visual inspections. Blower always needs service to check the direction of blower, nameplate, and motor and fan rotation shown on the motor. Incorrect mounting or a tightened belt produces vibrations on the pulley blower side, causing belt and bearing damage. Bad belts can cause problems of vibration, dust and heat at the end of the pulley blower. Poor filtration can affect the quality of process air. As a result, the substance in the air of the impeller accumulates, rolls the gap, causing the pads to fail, locking the blower.
Design of the air knife
Many manufacturing processes use air curtains for drying, film control and wet tissue products. For example, an air knife including a cylindrical plenum that extends across the width of the product line has a slot along its length. Air is supplied to the courtroom at high pressure, and passes through the gap with a high-speed “knife” of air and the shock of the underlying product line. The traditional multi-nozzle system can supply air through a belt-driven single-step blower.
Using a single continuous nozzle longer than a double nozzle can degrade performance and reduce the noise output of the nozzle itself. If the air supply room is designed aerodynamically close to the entrance of the knife nozzle, the jet noise can be reduced even further.
This type of dryer uses a straightforward two-tiered centrifugal blower, capable of reaching about 110 liters per second, a maximum of 16 kilopascals per second
