山东空压机主机维修的正确操作规范

空压机主机维修是针对空压机维修保养中重要的一个环节，更好的保养空压机转子与轴承能很好的维护机器使用年限，当喷油螺杆压缩机使用时间过长，螺杆转子可能会出现以下问题：关于空压机主机中转子维修的损害 ：轴承磨损 、啮合间隙过大 、油路不畅 、振动、运行噪声过大造成问题的原因是因为转子长时间在高负荷及高温度下运行难免将产生机械磨损和疲劳，如果不进行及时的检查及修理，您将可能面临很多损失。

The maintenance of air compressor host is an important link in the maintenance of air compressor. Better maintenance of air compressor rotor and bearing can well maintain the service life of the machine. When the oil injection screw compressor is used for a long time, the screw rotor may have the following problems: the damage of the rotor repair in the air compressor host: bearing wear, excessive meshing clearance, poor oil path The reason for the problem is that the rotor will inevitably suffer from mechanical wear and fatigue when it runs under high load and high temperature for a long time. If you do not carry out timely inspection and repair, you may face a lot of losses.

引起轴承损伤的原因很多，诸如安装不当、污物侵入或水分侵入等是很多轴承早期损伤的常见原因。以下是一些大尺寸轴承的常见损坏原因分析以及相应的能延长轴承寿命的预防措施。

There are many reasons for bearing damage, such as improper installation, dirt intrusion or moisture intrusion. The following is a number of large-scale bearing damage cause analysis and the corresponding measures to extend the bearing life.

操作不当：安装、操作或拆卸不当可能引起保持架变形或缺损预防措施：使用合适的操作、安装和拆卸工具。

Improper operation: improper installation, operation or disassembly may cause deformation or defect of cage preventive measures: use appropriate operation, installation and removal tools.

润滑不充分：润滑不充分或不当可能导致元件擦伤或者严重的轴承变形预防措施：改进润滑系统，定时恰当地补充或更换润滑剂。

Inadequate lubrication: inadequate or improper lubrication may result in component scuffing or severe bearing deformation. Preventive measures: improve the lubrication system and replenish or replace the lubricant properly at regular intervals.

生锈与腐蚀：接触水可能导致轴承元件蚀损并生锈。锈蚀损伤后的轴承

Rust and corrosion: contact with water may cause corrosion and rust of bearing elements. Bearing damaged by corrosion

在工作时可能导致剥落预防措施：定期检查密封，保证良好的密封效果，正确储存轴承。

Preventive measures: regularly check the seal to ensure good sealing effect and store the bearing correctly.

电流：轴承转动时通电可能导致出现凹槽或刻痕。轴承静止时，电气操作接地不当会导致轻微的烧伤预防措施：在对轴承以外的部件焊接前通过适涤地连接减少或避免电流通过轴承。

Current: energizing the bearing as it rotates may cause grooves or nicks. When the bearing is stationary, improper grounding of electrical operation may cause slight burn. Preventive measures: reduce or avoid the current flowing through the bearing through a suitable polyester connection before welding the parts other than the bearing.

外部材料：磨损性颗粒污染和碎片侵入可能导致轴承工作面磨损、擦伤和凹陷预防措施：清理侵入颗粒和碎片，更换润滑剂，检查密封系统。偏心：偏心、倾斜或过大负荷可能导致几何应力集中或表面剥落预防措施：准确加工轴承座和挡肩。

External materials: abrasive particle contamination and debris intrusion may cause wear, scuffing and dents on the bearing working surface preventive measures: clean up the invasive particles and debris, replace the lubricant, and check the sealing system. Eccentricity: eccentricity, inclination or excessive load may lead to geometric stress concentration or surface spalling preventive measures: accurately process bearing pedestal and shoulder.
