outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 子棉烘干机性能的评价应依据“烘干机国家行业标准”并从实用性角度考虑。即评价烘干机性能的主要指标是能量消耗、经一次干燥除水率、干燥不均匀度和安全运转率。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 1.能量消耗<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 能量消耗包括热能消耗和电能消耗。热能消耗通过下式计算:</span></p><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; font-size: 14px; text-align: center; line-height: 1.75em; overflow-wrap: break-word !important;

outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; font-size: 14px; line-height: 1.75em; overflow-wrap: break-word !important;

margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 2.经一次干燥除水率<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 经一次干燥除水率并不是越高越好,因为进入锯齿轧花机子棉的含水率在7%～9%是轧花系统的最佳工作条件,此时棉纤维的产量最高、质量最好、机器工作最稳定、设备和工艺的故障率最低。所以,对于超水分子棉,经一次烘干后含水率在7%～9%最佳。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 3.干燥不均匀度<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 干燥不均匀度是指子棉经烘干后最高含水率与最低含水率之差,标准中规定干燥不均匀度不能超过1%,也就是要求烘干机烘后子棉的含水率应尽量一致,不能有的干,有的湿。否则影响后续子棉的加工。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 4.安全运转率<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 烘干机应不堵塞,能连续长期工作,不能因使用了烘干机而影响轧花厂的正常生产。</span></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%;
