Foreword

感谢您选用了我厂的ZGM123G-Ⅲ型中速辊式磨煤机,为了使您更好地了解设备,使设备更好地为您的系统服务,我们编写了这本使用说明书,希望能给您以帮助,并真诚地希望您对其中的不足之处给予指出。 Thank you for selecting our ZGM123G-Ⅲ mill. To be able to operate the mill properly and serve for your system successfully, this operation manual is necessary for you to read before operating the mill. In the meantime, your comments are of great value. 本使用说明书是根据中速辊式磨煤机的特点和现场运行情况编写的,其中对磨煤机的运行、检查、维护、检修要求大部分是针对磨煤机易出问题的环节和总结现场出现的问题而提出的,所以下面提出的要求,用户在使用过程中请务必遵守: This manual has been revised project by project. If you have any comments or question, don’t hesitate to contact our service engineer at site or service department. Generally speaking, the following regulations shall be observed during operation, inspection and maintenance. ①磨煤机运行应严格按照运行要求,不能违章操作。 ①As for operation of the mill, the stipulation about installation, commissioning and maintenance shall be followed. ②必须保证一次风量,一次风量的测量装置要定期标定,这对磨煤机运行极为重要。 ②The sufficient primary air is essential to the steady operation. Therefore the measurement of the hot primary air shall be updated regularly. ③定期对磨煤机检查、维护,绝不允许连续数千小时不停磨、不检查、不间断地运行。 ③As to the maintenance of the mill, the routine inspection shall be performed. ④一次风入口隔绝门至关重要,没有严密的隔绝门就无法进入磨内检查、维护和检修。 ④It is important that isolating values will be installed at the inlet of hot primary air . ⑤出粉管上要有隔绝门。 ⑤The isolating values shall be operation, which installed at the outlet of coal powder. ⑥必须为检查、维护、检修工作创造必要的条件。 ⑥It is important that suppling condition to check, maintenance and repaire. ⑦应配置单独的密封风系统,不要直接采用冷一次风作为密封风。 ⑦Regarding the sealing air system, the independent sealing air system shall be equipped. The hot primary air shall not be used as sealing air.
