工程机械零件在装配前、装配中、装配后大都需要进行清洗,有些零件还根据需要在试运行后进行清洗。清洗零件的目的是清除其表面残留的铸造型砂、铁屑、铁锈、研磨剂、油污、尘土等各种污物。零件清洗后的洁净程度将直接影响装配质量和工程机械的使用寿命,因此零件的清洗工作是工程机械装配中十分重要的环节。做好零件的清洗工作,应根据其材料、结构特点、污染情况以及对其清洁度要求等,正确选用清洗剂和清洗方法。
Construction machinery parts before assembly, assembly, the assembly after most of the need for cleaning, some parts are also needed after the test run for cleaning. The purpose of cleaning parts is to remove the surface of the remaining casting sand, iron, rust, abrasive, oil, dust and other dirt. The cleanliness of parts after cleaning will directly affect the assembly quality and service life of construction machinery, so the cleaning of parts is a very important part in construction machinery assembly. Do a good job cleaning parts, should be based on their materials, structural characteristics, pollution and its cleanliness requirements, the correct choice of cleaning agents and cleaning methods.
