Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee of mechanical separation (SAC/TC92) centralized. This standard is drafted by. China Shipbuilding Diesel Engine Co., Ltd. Anqing, Hefei General Machinery Research Institute, Zhejiang Light Industry Machinery Industry Co., CSSC Nanjing Luzhou Machine Co., Ltd., Shanghai Mechanical and Electrical Plant sea. The main drafters of this standard. and Cao Li, WANG Liang-en, Zhangde You, Wu will be days, Sunzi Hong, Zhou Jin, Zhao Zhong Guan, Li Zhenwei, XIAO Hai, Wanggui Yun.

Introduction

This standard is mainly based on ISO 11342.1998 "Mechanical vibration mechanically flexible rotor balancing methods and guidelines", GB/T 6557- 2009 "flexible rotor balancing mechanical methods and guidelines", GB/T 9239 "Mechanical vibration steady state (rigid) rotor balancing quality requirements" and The actual needs of the separation machinery industry status and development to develop, on the relevant technical content GB/T 6557-2009 equivalent, and GB/T 6557-2009 on technical content and is equivalent to the ISO 11342.1998. In recent years, various types of centrifuges, separator drum and rotor balancing technology at home and abroad with new development, and has accumulated more balance Practical experience, in order to further improve the safety and reliability of the centrifuge, separator, reducing machine vibration standard is formulated to meet the separation machinery The industry needs to improve product quality and technical capabilities. The standard machinery on the flexible rotor balancing method and criteria equivalent GB/T 6557-2009, in line with the truth and of the separation machinery industry Dovetail with national standards and is conducive to international standards. Of course, there are differences in the breakdown of the development of other technical content. Centrifuge separator drum balance test specification

1 Scope

This standard specifies the criteria for industrial centrifuge drum balance, balance separator drum guidelines, drum balance correction, drum balance correction people Members and safety requirements balance correction, drum balance correction reports test specifications and requirements. This standard applies to all kinds of a metal drum (with or without liner bag liner bag) industrial centrifuges, including industrial dewatering machine (hereinafter referred to as centrifugal Machine) and a variety of industrial disc separator, tubular separator chamber separator (hereinafter referred to as separator) drum balance and current balance on the device Field correction.

3 Terms and Definitions

GB/T 4774, GB/T 6444 defined by the following terms and definitions apply to this document. 3.1 Rigid rotor rigidrotor At any speed up to the maximum operating speed of rotation of the deflection by the distribution of a given amount of unbalance is below the allowable limit Rotor. 3.2 Flexible rotor flexiblerotor Since the elastic deflection of the rotor can not be considered to be rigid. Note 1. The elastic deflection means bending deformation within the elastic range of the rotation of the rotor. Note 2. GB/T 6557-2009 Appendix H gives the definition of the relevant terms of flexible rotors can be used as a reference. 3.3 Residual unbalance residualunbalance Rotor unbalance remaining balance after any form. ...
