羅茨鼓風機卡住了怎么修：羅茨風機卡死的維修技巧，羅茨鼓風機抱死轉不動是什么原因

　　備用或長期停放的羅茨鼓風機重新啟動很容易出現各種問題，常見問題就是抱死轉不動的情況是什么原因呢?下面小編給大家介紹下三葉羅茨鼓風機轉不動的原因。

　　1.齒輪損壞

　　正常齒輪咬合面積在2/3左右，而大于這個咬合面積，齒輪之間咬合力過大，致使齒輪無法轉動，進而引起風機轉不動的情況。

　　2.生銹卡死

　　羅茨風機閑置的時間久了，會在內部外部出現生銹的現象，葉輪與墻板或機殼繡在一起;或者鐵銹出現了大面積的脫落，葉輪之間就可能出現卡死的情況。這樣的情況需要用煤油浸泡、汽油沖洗等手段對鐵銹進行清理，并進行間隙調整。

　　3.異物卡死

　　有大顆粒物體進入風機腔體里，堵塞各部分間隙，造成風機無法轉動。這種需要清理腔體里面的異物，并檢查葉輪之間的間隙。另檢查異物落入的原因，避免故障再次發生。

　　4.葉輪損壞

　　葉輪損壞風機卡死轉不動，這種故障我們很容易理解，葉輪與葉輪之間互相咬合，導致葉輪轉不動，這種故障需要對機殼進行拆卸檢查。

　　5.軸承損壞

　　羅茨鼓風機上面有4個軸承，如果軸承損壞，會造成葉輪與葉輪、機殼、墻板之間的間隙變化，出現葉輪摩擦的情況，導致風機不能轉動，這就是導致葉輪間隙變化的間接原因，也是導致葉輪不能轉動的常見原因。

　　6.零部件變形

　　零部件變形造成三葉羅茨鼓風機轉不動的情況很少見，有很少一部分生產廠家一味降低成本致使零部件強度不達標，同一型號價錢偏低的羅茨風機，很可能存在鑄件厚度偏薄、軸頸偏細等情況，如果零件強度不達標就可能出現零件變形的情況，破壞各零部件之間的間隙，造成風機卡死轉不動。另產品長期放置，也會造成零部件一定的變形。

　　7. 電機損壞

　　閑置久的三葉羅茨鼓風機，如果存在電機故障，自然會產生轉不動的情況，故障很容易判斷，電機不能轉動，風機自然不會轉動，如果是電機出現故障，應當對風機的電機進行檢查，然后排出故障。

　　羅茨鼓風機抱死轉不動的原因有很多，如軸承出現了損壞、齒輪損壞、機殼變形等，很多情況都會讓羅茨鼓風機抱死轉不動，今天錦工風機要和大家分享一個客戶的案例，羅茨鼓風機典型的抱死案例，羅茨鼓風機葉輪上面有很多的灰塵，并且已經積攢了很多，這是羅茨鼓風機抱死的直接原因，造成羅茨鼓風機內部出現大量灰塵的原因有二：

　　首先，輸送的氣體含有大量的粉塵，粉塵進入羅茨鼓風機內部之后，不斷地進行積累，慢慢地造成了葉輪的相互摩擦抱死。

　　其次，羅茨鼓風機濾芯失效，羅茨鼓風機的濾芯在長期的使用過程中，過濾效果下降，造成風機吸入過多的灰塵。

　　該客戶的使用現場是這樣的，可以想象羅茨鼓風機為什么抱死了吧?這現場環境比較惡劣，再好的羅茨風機長期使用下去也會出問題，該客戶出現抱死情況之后，聯系到我們，我們建議客戶對羅茨風機進行清洗，并定期更換濾芯，間隔一段時間進行一次大的清洗保養。

　　羅茨鼓風機卡住了怎么修：羅茨風機卡死的維修技巧，羅茨鼓風機的維修方法

　　羅茨鼓風機是現在生活中必不可少的產品，但是在我們長時間進行使用的時候就需要我們進行正確的保養以及維護，那么接下來就讓我們來教給您方法。

　　1、檢查各部位的緊固情況及定位銷是否有松動現象;

　　2、鼓風機機體內部是否有漏水、漏油現象;

　　3、鼓風機機體內部不能有結垢、生銹和剝落現象存在;

　　4、注意潤滑及冷卻情況是否正常，注意潤滑的質量。經常傾聽鼓風機運行有無雜聲。注意機組是否在不符合規定的工況下運行;

　　5、鼓風機的過載，有時不是立即顯示出來的，所以要注意進、排氣壓力，軸承溫度和電動機電流的增加趨勢，籍以判斷機器是否運行正常;

　　6、羅茨鼓風機拆卸機器前，應對機器各配合尺寸進行測量，作好記錄，并在零部件上作好標記，以保證裝配后保持原來配合要求;

　　7、鼓風機的軸承與齒輪采用飛濺潤滑，建議用N68-N150中極壓工業齒輪油用戶也可自行選用合適的潤滑油，須保證潤滑油與上述潤滑油性能相當以利于齒輪與軸承正常運行，油箱中的油量在停車時要保證在油標中線以上3—5mm 潤滑油要定期更換(**次啟動工作200小時、換**次油)，以后每半年換油。注入新油前應用中性煤油把油箱和齒輪清洗干凈;

　　8、維護檢修應按具體使用情況擬定合理的維修制度，按期進行，并作好記錄，建議每年大修一次，并更換軸承和有關易損件。

　　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.
