A:The methods to improve the energy saving of plastic dryers are: optimize the drying process, accurately control the temperature and time; Upgrade the equipment with efficient heating elements and reasonable air ducts; Recovery of waste heat; Strengthen heat preservation; Reasonable selection; Use intelligent control. Combining these measures can significantly reduce energy consumption, improve efficiency, and realize energy saving and environmental protection production.
A:Plastic dryer is an important equipment for plastic processing. It can remove the moisture in plastic raw materials and ensure the quality of plastic products. Its working principle is based on technologies such as hot air circulation or vacuum drying. Common types are hot air and vacuum dryers. Selection should consider plastic characteristics, production scale and so on. It is of great significance to plastic processing.
A:Twin-screw extruder parts wear problems need attention. There are mainly three types of abrasive wear, corrosion wear and internal wear. The characteristics, characteristics and diagnostic methods are different. Reasons include material, environment, parameters, etc. Countermeasures include replacement of parts, selection of appropriate materials, strengthening maintenance and so on. Solving this problem can ensure production efficiency and product quality.
A:To determine the heating temperature and feeding speed of the plastic granulator, it is necessary to consider the type characteristics of plastics, product requirements, and equipment performance. Refer to the material manual and experience, experiment and explore. Heating temperature depends on plastic melting point and thermal stability, feeding speed depends on equipment capacity, screw speed and plastic fluidity, observation and adjustment to the best.
A:When using the plastic granulator, pay attention to: check the connection of the components before starting; Set the heating temperature according to the type of plastic to avoid too high or too low; Keep the feeding speed uniform and stable; Pay attention to safety protection, no limb extension; Regular maintenance; Stop immediately in case of failure; Shut down according to the procedures.
A:The precision of pressure sensor has great influence on plastic extrusion machinery. High precision can accurately reflect pressure changes to ensure stable product quality, such as dimensional accuracy and physical properties; It can also accurately adjust process parameters, optimize energy consumption, reduce waste and reduce costs, and accurately evaluate equipment status. Insufficient precision, on the other hand, affects production efficiency and product quality.
