漳州移动螺杆空压机维修保养一、光滑油缘由
I. The Reasons for Smooth Oil
1、机头内部油量缺乏，暂时停用(包括运输)。形成霎时缺油，招致卡死，所以暂时停机的设备要先往机头内加足量的油，再起机。
1. The engine nose is short of oil and is temporarily suspended (including transportation). Suddenly oil shortage causes stuck, so temporary shutdown e should first add sufficient oil to the nose, and then start up.
2、光滑油改换或添加不及时，供油缺乏。或油路梗塞、泄露，招致机头缺油卡死。
2. The change or addition of smooth oil is not timely and the supply of oil is insufficient. Or oil road obstruction, leakage, resulting in engine head oil shortage stuck.
3、杂质太多积碳，结焦。所以选光滑油，改换光滑油比拟关键;运用劣质光滑油或超期运用时更容易发作此类事故。在这个时分机头卡死处置办法：必需拆检，用清洗剂浸泡五个小时就能够恢复。
3. Too many impurities accumulate carbon and coke. Therefore, it is crucial to choose smooth oil and replace it; it is easier to have such accidents when using inferior smooth oil or overdue use. At this time, the machine head jam disposal method: must be disassembled and inspected, soaked with detergent for five hours can be restored.
二、转子缘由
2. Rotor Reasons
1、招致转子直接接触爆死。主机轴承发作磨损，从而招致螺杆发作轴向窜动及径向窜动增大，该变化会让螺杆与螺杆之间、螺杆与主机壳体及前后端面之间的间隙发作变化。该间隙变化在轴承寿命期限内是正常的允许的而由此产生的空压机产气量衰减及传动电机负荷增加也是正常的允许的。
1. Causing the explosion of the rotor in direct contact. The abrasion of the main bearing results in the increase of the axial and radial channeling of the screw, which will change the clearance between the screw and the screw, between the screw and the main body shell and between the front and rear end faces. The change of clearance is normally allowed during the life of bearing, and the resulting air compressor gas production attenuation and transmission motor load increase are also normally allowed.
2、轴承老化，磨损严重，详细检测轴承磨损程度能够在轴承没拆下时，拨动轴承内下侧滚针或滚珠，如能轻松拨动阐明需求改换了;随着空压机运转时间的推移。就可能发作严重结果。但是当轴承磨损及主机配合间隙超越允许的极限量后。1毫米厚这么一块铁屑进去了也都卡死。特别的有异物掉入卡死。
2. Bearing aging, serious wear, detailed detection of bearing wear degree can be in the bearing without removal, pull the needle or ball, if you can easily dial to clarify the need for change; with the passage of the running time of the air compressor. Serious outcomes may occur. But when the bearing wear and the main engine clearance exceed the allowable limit. A scrap of iron as thick as one millimeter stuck when it went in. In particular, foreign bodies fell into the jam.
3、主机内部螺杆与前后端面之间、螺杆与主机壳体之间会发作磨擦。首先，电机负荷急剧增加，Zui严重的结果就是螺杆抱死以至主机报废，假如电机维护反响不灵活或失效则可能招致电机烧毁。
3. Friction will occur between the internal screw and the front and rear end surfaces of the main engine, and between the screw and the main engine shell. First of all, the load of the motor increases sharply, the most serious result is screw locking and even the main engine scrap, if the motor maintenance response is not flexible or failure may cause motor burning.
