Asphalt gear pump several major development direction
Asphalt gear pump several major directions Extruder high-speed, high yield, allows investors to lower input to obtain greater output and high returns. However, the high speed extruder asphalt gear pump speed also brought a series of difficulties to be overcome: If the material in the screw residence time reduction will lead to uneven plasticizing material mixing, material over-shear may cause rapid heating material And thermal decomposition, extrusion stability control difficulties will cause the extrusion geometry fluctuations, related auxiliary devices and control system accuracy must be increased, screw and barrel wear and tear need to use high wear-resistant and ultra-high wear-resistant material, Reducer and bearings at high speed in the case of how to improve their life and other issues need to be resolved. Asphalt gear pump efficiency is mainly reflected in the high output, low energy consumption, low manufacturing costs. In terms of function, the screw extruder has been used not only for the extrusion molding and mixing of polymer materials, but also has been expanded to feed, electrode, explosive, building materials, packaging, pulp, ceramics and other fields. In addition, the mixing granulation and extrusion processes combined one-step extrusion process is also worthy of attention. To achieve large-scale extrusion equipment can reduce production costs, which in large asphalt pump gear, blown film crew, pipe extrusion unit, etc. more obvious advantages. Large-scale extrusion granulation units, one of the three key equipment required for large-scale ethylene projects, rely on import for major technological equipment required by the state key construction services and the localization process must be accelerated. The precision of the product can increase the gold content, such as composite films are required precision extrusion, and as an important means of precision extrusion - melt gear pump must increase efforts to carry out research and development. Modular production can be adapted to the special requirements of different users, shorten the R & D cycle of new products and strive for greater market share; and specialized production can make all system module components of extrusion equipment to fixed-point production or even global procurement, Ensure the quality of the entire period, reduce the cost of asphalt gear pump, accelerate capital turnover are very beneficial.
