罗茨鼓风机卡住了怎么修：罗茨风机卡死的维修技巧，罗茨鼓风机抱死转不动是什么原因

　　备用或长期停放的罗茨鼓风机重新启动很容易出现各种问题，常见问题就是抱死转不动的情况是什么原因呢?下面小编给大家介绍下三叶罗茨鼓风机转不动的原因。

　　1.齿轮损坏

　　正常齿轮咬合面积在2/3左右，而大于这个咬合面积，齿轮之间咬合力过大，致使齿轮无法转动，进而引起风机转不动的情况。

　　2.生锈卡死

　　罗茨风机闲置的时间久了，会在内部外部出现生锈的现象，叶轮与墙板或机壳绣在一起;或者铁锈出现了大面积的脱落，叶轮之间就可能出现卡死的情况。这样的情况需要用煤油浸泡、汽油冲洗等手段对铁锈进行清理，并进行间隙调整。

　　3.异物卡死

　　有大颗粒物体进入风机腔体里，堵塞各部分间隙，造成风机无法转动。这种需要清理腔体里面的异物，并检查叶轮之间的间隙。另检查异物落入的原因，避免故障再次发生。

　　4.叶轮损坏

　　叶轮损坏风机卡死转不动，这种故障我们很容易理解，叶轮与叶轮之间互相咬合，导致叶轮转不动，这种故障需要对机壳进行拆卸检查。

　　5.轴承损坏

　　罗茨鼓风机上面有4个轴承，如果轴承损坏，会造成叶轮与叶轮、机壳、墙板之间的间隙变化，出现叶轮摩擦的情况，导致风机不能转动，这就是导致叶轮间隙变化的间接原因，也是导致叶轮不能转动的常见原因。

　　6.零部件变形

　　零部件变形造成三叶罗茨鼓风机转不动的情况很少见，有很少一部分生产厂家一味降低成本致使零部件强度不达标，同一型号价钱偏低的罗茨风机，很可能存在铸件厚度偏薄、轴颈偏细等情况，如果零件强度不达标就可能出现零件变形的情况，破坏各零部件之间的间隙，造成风机卡死转不动。另产品长期放置，也会造成零部件一定的变形。

　　7. 电机损坏

　　闲置久的三叶罗茨鼓风机，如果存在电机故障，自然会产生转不动的情况，故障很容易判断，电机不能转动，风机自然不会转动，如果是电机出现故障，应当对风机的电机进行检查，然后排出故障。

　　罗茨鼓风机抱死转不动的原因有很多，如轴承出现了损坏、齿轮损坏、机壳变形等，很多情况都会让罗茨鼓风机抱死转不动，今天锦工风机要和大家分享一个客户的案例，罗茨鼓风机典型的抱死案例，罗茨鼓风机叶轮上面有很多的灰尘，并且已经积攒了很多，这是罗茨鼓风机抱死的直接原因，造成罗茨鼓风机内部出现大量灰尘的原因有二：

　　首先，输送的气体含有大量的粉尘，粉尘进入罗茨鼓风机内部之后，不断地进行积累，慢慢地造成了叶轮的相互摩擦抱死。

　　其次，罗茨鼓风机滤芯失效，罗茨鼓风机的滤芯在长期的使用过程中，过滤效果下降，造成风机吸入过多的灰尘。

　　该客户的使用现场是这样的，可以想象罗茨鼓风机为什么抱死了吧?这现场环境比较恶劣，再好的罗茨风机长期使用下去也会出问题，该客户出现抱死情况之后，联系到我们，我们建议客户对罗茨风机进行清洗，并定期更换滤芯，间隔一段时间进行一次大的清洗保养。

　　罗茨鼓风机卡住了怎么修：罗茨风机卡死的维修技巧，罗茨鼓风机的维修方法

　　罗茨鼓风机是现在生活中必不可少的产品，但是在我们长时间进行使用的时候就需要我们进行正确的保养以及维护，那么接下来就让我们来教给您方法。

　　1、检查各部位的紧固情况及定位销是否有松动现象;

　　2、鼓风机机体内部是否有漏水、漏油现象;

　　3、鼓风机机体内部不能有结垢、生锈和剥落现象存在;

　　4、注意润滑及冷却情况是否正常，注意润滑的质量。经常倾听鼓风机运行有无杂声。注意机组是否在不符合规定的工况下运行;

　　5、鼓风机的过载，有时不是立即显示出来的，所以要注意进、排气压力，轴承温度和电动机电流的增加趋势，籍以判断机器是否运行正常;

　　6、罗茨鼓风机拆卸机器前，应对机器各配合尺寸进行测量，作好记录，并在零部件上作好标记，以保证装配后保持原来配合要求;

　　7、鼓风机的轴承与齿轮采用飞溅润滑，建议用N68-N150中极压工业齿轮油用户也可自行选用合适的润滑油，须保证润滑油与上述润滑油性能相当以利于齿轮与轴承正常运行，油箱中的油量在停车时要保证在油标中线以上3—5mm 润滑油要定期更换(**次启动工作200小时、换**次油)，以后每半年换油。注入新油前应用中性煤油把油箱和齿轮清洗干净;

　　8、维护检修应按具体使用情况拟定合理的维修制度，按期进行，并作好记录，建议每年大修一次，并更换轴承和有关易损件。

　　How to repair roots blower stuck: maintenance skills of Roots blower stuck, and what is the reason for Roots blower locked and unable to rotate

　　It is easy to have various problems when the roots blower that is standby or has been parked for a long time is restarted. The common problem is that what is the reason for the locked rotation? The following editor will introduce the reason why the three blade roots blower doesn't work.

　　1. Gear damage

　　The bite area of normal gears is about 2/3. If it is larger than this bite area, the bite force between gears is too large, which makes the gears unable to rotate, thus causing the fan to stop rotating.

　　2. Rust and jamming

　　If roots blower is idle for a long time, rust will appear inside and outside, and the impeller will be embroidered with the wallboard or casing; Or the rust falls off in a large area, and the impeller may be stuck. In this case, it is necessary to clean the rust and adjust the clearance by means of kerosene immersion, gasoline flushing, etc.

　　3. Foreign matters are stuck

　　There are large particles entering the fan cavity, blocking the gap between various parts, causing the fan to fail to rotate. This requires cleaning the foreign matters in the cavity and checking the clearance between the impellers. In addition, check the cause of foreign matter falling to avoid the recurrence of the fault.

　　4. Impeller damage

　　The impeller is damaged, and the fan is stuck and cannot rotate. This fault is easy to understand. The engagement between the impeller and the impeller causes the impeller to not rotate. This fault requires disassembly and inspection of the casing.

　　5. Bearing damage

　　There are four bearings on the roots blower. If the bearings are damaged, the gap between the impeller and the impeller, the casing and the wallboard will change, and the impeller friction will occur, resulting in the fan can not rotate. This is the indirect reason for the change of the impeller gap and the common reason for the impeller can not rotate.

　　6. Deformation of parts

　　It is rare for the three blade roots blower to stop rotating due to the deformation of parts and components. A few manufacturers blindly reduce costs, resulting in the strength of parts and components not up to standard. The roots blower with the same model and low price is likely to have thin casting thickness and thin journal. If the strength of parts is not up to standard, parts and components may be deformed, damaging the gap between parts and components, causing the fan to lock and stop rotating. In addition, long-term placement of products will also cause certain deformation of parts.

　　7. Motor damage

　　The three blade roots blower, which has been idle for a long time, will naturally stop rotating if there is a motor fault. The fault is easy to judge. The motor cannot rotate, and the fan will not rotate naturally. If there is a motor fault, the motor of the fan should be checked, and then the fault should be eliminated.

　　There are many reasons for Roots blower to lock up and stop rotating, such as bearing damage, gear damage, casing deformation, etc. many situations will make roots blower lock up and stop rotating. Today, Jingong blower wants to share with you a customer's case. A typical locking case of Roots blower is that there is a lot of dust on the impeller of Roots blower, and a lot of dust has accumulated, which is the direct reason for Roots blower locking up, There are two reasons for a large amount of dust in Roots blower:

　　First of all, the conveyed gas contains a lot of dust. After entering the roots blower, the dust continues to accumulate, slowly causing the mutual friction and locking of the impellers.

　　Secondly, the filter element of Roots blower fails. During the long-term use of the filter element of Roots blower, the filtering effect decreases, causing the fan to inhale too much dust.

　　The customer's use site is like this. Can you imagine why the roots blower is locked? The on-site environment is relatively bad, and even the best roots blower will have problems if it is used for a long time. After the customer has locked up, contact us, and we recommend the customer to clean the roots blower, replace the filter element regularly, and carry out a major cleaning and maintenance at intervals.

　　How to repair roots blower stuck: maintenance skills of Roots blower stuck, maintenance methods of Roots blower

　　Roots blower is an indispensable product in our life now, but we need to carry out correct maintenance and repair when we use it for a long time. Then let's teach you the method.

　　1. Check the fastening of each part and whether the locating pin is loose;

　　2. Whether there is water leakage or oil leakage inside the blower body;

　　3. There shall be no scaling, rust and peeling inside the blower body;

　　4. Pay attention to whether the lubrication and cooling conditions are normal, and pay attention to the quality of lubrication. Always listen to whether the blower operates with noise. Pay attention to whether the unit operates under conditions that do not meet the regulations;

　　5. Sometimes the overload of the blower is not immediately displayed, so pay attention to the increasing trend of inlet and exhaust pressure, bearing temperature and motor current, so as to judge whether the machine operates normally;

　　6. Before disassembling the machine, the roots blower shall measure the matching dimensions of the machine, make records, and mark the parts to ensure that the original matching requirements are maintained after assembly;

　　7. The bearings and gears of the blower adopt splash lubrication. It is recommended to use n68-n150 medium extreme pressure industrial gear oil. Users can also choose suitable lubricating oil by themselves. It must be ensured that the performance of the lubricating oil is equivalent to that of the above lubricating oil, so as to facilitate the normal operation of gears and bearings. The oil volume in the oil tank should be ensured to be 3-5mm above the centerline of the oil standard when it is stopped. The lubricating oil should be changed regularly (the first start-up work for 200 hours, the first oil change), and then every six months. Clean the oil tank and gear with neutral kerosene before injecting new oil;

　　8. A reasonable maintenance system shall be formulated according to the specific use conditions for maintenance and overhaul, which shall be carried out on schedule and recorded. It is recommended to overhaul once a year and replace the bearings and relevant vulnerable parts.
