A:The application of pressure sensors in plastic extrusion machinery has brought significant advantages from many aspects such as product quality, production efficiency, equipment maintenance and process innovation, which helps to enhance the competitiveness and economic benefits of enterprises.
A:The electromagnetic heating ring works on the principle of electromagnetic induction. It generates an alternating magnetic field in the coil through alternating current, which causes eddy currents inside the heated object, and the eddy currents cause the object to heat itself. This method has high energy conversion efficiency, can directly heat the object, reduce heat loss, and is widely used in heating scenarios such as wood-plastic equipment.
A:The main types of heating rings of wood-plastic equipment are: cast aluminum heating rings, high heat transfer efficiency and moderate price; Ceramic heating ring, high temperature resistance, good insulation; Stainless steel heating ring, durable, corrosion resistant; Electromagnetic heating ring, energy saving and accurate temperature control; Mica heating ring, light and cheap.
A:Corrosion by chemical substances, such as strong acids and bases; Physical wear, such as water shock and friction; A large number of organisms attach and block pores; Material natural aging; Improper installation causes deformation or looseness of the interface; Too high gas supply pressure causes it to break; Blockage of foreign bodies causes excessive local pressure. All these may affect the performance and life of aerator.
A:The surface roughness of the traction roll is important. The roughness is too large, the tensile rod is easy to be deformed and broken by strong tension, and the surface is easy to have scratches; If the roughness is too small, the traction force is insufficient, the pull rod jitter and the size is not allowed. The measurement and evaluation can be done by using stylus displacement to obtain contour data and calculate roughness parameters. It can also be measured by optical method, using the light principle. The roughness range can also be estimated by comparing with the standard sample.
A:Drawing roller is the key component of drawing machine. It is usually made of metal and may have a rubber layer on the surface to increase friction. Its role is to generate enough traction through contact with the material to drive the strip forward at a constant speed to ensure the uniform size of the strip and good surface quality. The precision and performance of the traction roll directly affect the working efficiency and product quality of the stretcher.
