影响挤压机模板使用周期因素探讨
|
摘要
聚丙烯挤压机模板是挤压机日常运行的重要配件,在维修费用中占据很高的比例。在模板运行后期,常常出现粒型大小不均、拖尾料、细屑等状冴,只能迚行重新修复或整台更换,且消耗工时较长。通过模板运行期间的表观状态,分析了其影响使用周期因素,延长使用寿命,降低设备维护费用。
Polypropylene extrusion machine template is an important part of extrusion machine, and its daily maintenance cost occupies high proportion. When the extrusion machine template is close to its service life, there is often uneven grain size, trailing material, fine chips and other problems in the production, so the extrusion machine template must be repaired or replaced, which will take a long time. In this paper, the apparent state of the template during the operation was analyzed, the factors affecting its service life were investigated, and some measures were put forward to prolong the service life and reduce the equipment maintenance cost.
