Scan WeChatHow to control the noise of fan products? Noise comes from the vibration of objects, and fan noise mainly consists of three parts: 1. Solid vibration radiation noise generated by general vibration of fan rotation, electromagnetic noise during motor operation; 2. The aerodynamic noise radiated from the air inlet and outlet (* * * the main source of noise), as well as the dynamic ···
High pressure fans are mostly used in industrial production and are widely used in environmental water treatment, such as aeration of sewage to meet the oxygen requirements of aerobic microorganisms in activated sludge and the conditions for full contact and mixing of sewage and activated sludge, thereby degrading various organic matter in water to achieve the purpose of sewage purif···
The efficiency of high-pressure fans is significantly affected by the type of motor used. Different IE (International Efficiency) levels such as IE1, IE2, IE3, IE4, and IE5 provide different levels of energy efficiency. Typical high-pressure fans use motors from IE1 to IE3, but Dereike is able to manufacture fans that use IE4 or even IE5 motors. This article explores the impact of di···
