羅茨風機常見故障及處理措施羅茨風機使用中常出現風機風量不足、電機超載、過熱、異響、無法正常啟動及振動大等故障，學會分析常見故障原因并了解相應的處理措施。

　　羅茨風機在日常使用過程中，難免會發生故障，了解羅茨風機常見故障、分析風機故障原因，才能知道怎么去處理或維修羅茨風機故障。

　　一、羅茨風機風量不足

　　風機風量不足是羅茨風機常見故障，發生故障后可檢查風機皮帶是否打滑掉轉;羅茨風機間隙是否增大;風機進口阻力是否增大。當我們分析出故障原因后，可通過調整羅茨風機皮帶張力、調整間隙、清洗風機過濾器，來恢復羅茨風機風量。

　　羅茨風機常見故障流量不足原因和解決方法：

　　1)進口過濾堵塞——清除過濾器的灰塵和堵塞物;

　　2)葉輪磨損，間隙增大得太多——修復間隙;

　　3)皮帶打滑——拉緊皮帶并增加根數;

　　4)進口壓力損失大——調整進口壓力達到規定值;

　　5)管道造成通風泄漏——檢查并修復管道。

　　二、電機超載

　　當羅茨風機出現電機超載故障時，我們可以排查羅茨風機過濾網是否堵塞負荷大;風機實際運行壓力是否超過出廠銘牌時標定的額定工作壓力，檢查葉輪與氣缸摩擦是否異常;我們可以通過清洗過濾器，控制實際壓力以及調整間隙來降低風機過載，處理羅茨風機電機超載現象。

　　羅茨風機常見故障電機超載原因和解決方法：

　　1)與規定壓力相比，壓差大，即背壓或進口壓力大;——降低壓力到規定值;

　　2)與設備要求的流量相比，風機流量太大，因而壓力增大——將多余氣體排放出去或降低鼓風機轉速;

　　3)進口過濾堵塞，出口管道障礙或堵塞——清除障礙物;

　　4)轉動部件相碰和摩擦卡住——立即停機，檢查原因;

　　5)油位太高——將油位調到正確位置。

　　6)窄V型皮帶過熱，振動過大，皮帶輪過小——調整皮帶輪尺寸。

　　三、羅茨風機過熱

　　當羅茨風機發生過熱故障時，可檢查羅茨風機油箱是否冷卻不良;風機轉子和氣缸壁摩擦是否異常;是否升壓太大，潤滑油是否添加過量;我們可以通過檢查冷卻水或油量，調整間隙，檢查吸入和排出壓力，同時控制油量的措施來處理羅茨風機過熱故障。對于溫度相對較高的工況環境下，為了保證風機的運轉穩定可靠，可選擇使用水冷式羅茨鼓風機。

　　羅茨風機常見故障溫度過高原因和解決方法：

　　1)油箱內油太多、太稠、太臟——降低油位或換油;

　　2)過濾器或消聲器堵塞——清除堵物;

　　3)壓力高于規定值——降低通過鼓風機的壓差;

　　4)葉輪過度磨損，間隙大——修復間隙;

　　5)通風不好，室內溫度高，造成進口溫度高——開設通風口，降低室溫;

　　6)運轉速度太低，皮帶打滑——加大轉速，防止皮帶打滑。

　　四、羅茨風機異響

　　當羅茨風機發生異響故障時，應檢查可調齒輪和轉子的位置是否失調，檢查軸承磨損是否嚴重，齒輪是否損傷。我們可通過按規定位置校正并鎖緊，更換羅茨風機軸承，更換設備齒輪等措施來處理羅茨風機異響故障。

　　羅茨風機常見故障葉輪與葉輪摩擦原因和解決方法：

　　1)葉輪上有污染雜質，造成間隙過小——清除污物，并檢查內件有無損壞;

　　2)齒輪磨損，造成側隙大——調整齒輪間隙，若齒輪側隙大于平均值30%～50%應更換齒輪;

　　3)齒輪固定不牢，不能保持葉輪同步——重新裝配齒輪，保持錐度 配合接觸面積達75%;

　　4)軸承磨損致使游隙增大——更換軸承。

　　五、羅茨風機無法正常啟動

　　當羅茨風機設備發生無法正常啟動故障時，可檢查進排氣口是否堵塞或閥門是否未打開，電氣是否出現問題;我們可以通過清理或打開風機閥門、檢修風機電氣來處理羅茨風機無法正常啟動故障。友情提示：很多羅茨風機無法正常啟動是因為齒輪油不足造成同步齒輪卡死了哦！

　　羅茨風機常見故障風機漏油或油泄露到機殼中的原因和解決方法：

　　1)油箱位太高，由排油口漏出——降低油位;

　　2)密封磨損，造成軸端漏油——更換密封;

　　3)壓力高于規定值——降低壓力到規定值;

　　4)墻板和油箱的通風口堵塞，造成油泄漏到機殼中——疏通通風口，中間腔裝上具有2mm孔徑的旋塞，打開墻板下的旋塞。

　　六、羅茨風機振動大

　　應檢查羅茨風機基本是否穩固，對輪是否趙正，軸承磨損是否異常。我們可通過對羅茨風機進行加固、緊固，找正對輪，更換軸承來處理羅茨風機振動大的故障。

　　羅茨風機常見故障異常或者振動原因和解決方法：

　　1)滾動軸承游隙超過規定值或軸承座磨損——更換軸承或軸承座;

　　2)齒輪側隙過大，不對中，固定不緊——重裝齒輪并確保側隙;

　　3)由于外來物和灰塵造成葉輪與葉輪、葉輪與機殼撞擊——清洗鼓風機，檢查機殼是否損壞;

　　4) 由于過載、軸變形造成葉輪碰撞——檢查背壓，檢查葉輪是否對中，并調整好間隙;

　　5) 由于過熱造成葉輪與機殼進口處磨擦——檢查過濾器及背壓，加大葉輪與機殼進口處間隙;

　　6) 由于積垢或異物使葉輪失去平衡——清洗葉輪與機殼，確保葉輪工作間隙;

　　7) 地腳螺栓及其他緊固件松動——擰緊地腳螺栓并調平底座。

　　Common faults and treatment measures of Roots blower in use, roots blower often has faults such as insufficient fan air volume, motor overload, overheating, abnormal noise, unable to start normally and large vibration. Learn to analyze the causes of common faults and understand the corresponding treatment measures.

　　Roots blower will inevitably break down in the process of daily use. Only by understanding the common faults of Roots blower and analyzing the causes of fan faults can we know how to deal with or repair roots blower faults.

　　1、 Insufficient air volume of Roots blower

　　Insufficient air volume of the fan is a common fault of Roots fan. After the fault occurs, check whether the fan belt slips and rotates; Whether the clearance of Roots blower increases; Whether the inlet resistance of the fan increases. After we analyze the cause of the fault, we can restore the air volume of Roots blower by adjusting the belt tension of Roots blower, adjusting the gap, and cleaning the blower filter.

　　Reasons and solutions for insufficient flow of Roots blower:

　　1) Inlet filter blockage - remove the dust and blockage of the filter;

　　2) The impeller is worn and the clearance is increased too much - repair the clearance;

　　3) Belt slipping - tighten the belt and increase the number;

　　4) Large inlet pressure loss - adjust the inlet pressure to the specified value;

　　5) Ventilation leakage caused by the pipe - check and repair the pipe.

　　2、 Motor overload

　　In case of motor overload fault of Roots blower, we can check whether the filter screen of Roots blower is blocked and loaded; Whether the actual operating pressure of the fan exceeds the rated working pressure calibrated on the factory nameplate, and check whether the friction between the impeller and the cylinder is abnormal; We can reduce the fan overload by cleaning the filter, controlling the actual pressure and adjusting the clearance, and deal with the overload of Roots blower motor.

　　Causes and solutions of motor overload:

　　1) Compared with the specified pressure, the pressure difference is large, that is, the back pressure or inlet pressure is large—— Reduce the pressure to the specified value;

　　2) Compared with the flow required by the equipment, the fan flow is too large, so the pressure increases - discharge the excess gas or reduce the blower speed;

　　3) The inlet filtration is blocked, and the outlet pipeline is blocked or blocked - remove the obstacles;

　　4) Collision and friction of rotating parts - stop the machine immediately and check the cause;

　　5) The oil level is too high - adjust the oil level to the correct position.

　　6) The narrow V-belt is overheated, the vibration is too large, and the pulley is too small - adjust the pulley size.

　　3、 Roots blower overheating

　　When the roots blower overheats, check whether the oil tank of the roots blower has poor cooling; Whether the friction between the fan rotor and the cylinder wall is abnormal; Whether the pressure rise is too high and whether the lubricating oil is added too much; We can deal with the overheating fault of Roots blower by checking the cooling water or oil volume, adjusting the clearance, checking the suction and discharge pressure, and controlling the oil volume at the same time. For working conditions with relatively high temperature, in order to ensure the stable and reliable operation of the fan, water-cooled roots blower can be selected.

　　Causes and solutions of high temperature of Roots blower:

　　1) The oil in the oil tank is too much, too thick, and too dirty - reduce the oil level or change the oil;

　　2) Filter or muffler blockage - remove the blockage;

　　3) Pressure higher than the specified value - reduce the differential pressure through the blower;

　　4) The impeller is excessively worn and the clearance is large - repair the clearance;

　　5) Poor ventilation, high indoor temperature, resulting in high inlet temperature - Open vents to reduce room temperature;

　　6) The running speed is too low and the belt slips - increase the speed to prevent the belt from slipping.

　　4、 Abnormal noise of Roots blower

　　In case of abnormal sound fault of Roots blower, check whether the position of adjustable gear and rotor is misadjusted, whether the bearing is seriously worn and whether the gear is damaged. We can deal with the abnormal sound fault of Roots blower by correcting and locking according to the specified position, replacing the bearings of Roots blower and replacing the gears of equipment.

　　Causes and solutions of impeller impeller friction:

　　1) There are pollutants and impurities on the impeller, resulting in too small clearance - remove the dirt and check whether the internals are damaged;

　　2) Gear wear, resulting in large side clearance - adjust the gear clearance. If the gear side clearance is greater than 30% - 50% of the average value, replace the gear;

　　3) The gear is not fixed firmly, and the impeller cannot be kept synchronized - reassemble the gear, and keep the taper fit contact area up to 75%;

　　4) Bearing wear increases the clearance - replace the bearing.

　　5、 Roots blower fails to start normally

　　When the roots blower fails to start normally, check whether the air inlet and exhaust ports are blocked, whether the valves are not opened, and whether there are electrical problems; We can deal with the failure of Roots blower to start normally by cleaning or opening the blower valve and overhauling the blower electrical. Tips: many roots blowers fail to start normally because the synchronous gear is stuck due to insufficient gear oil!

　　Causes and solutions of fan oil leakage or oil leakage into the casing:

　　1) The oil tank is too high and leaks through the oil drain - reduce the oil level;

　　2) The seal is worn, causing oil leakage at the shaft end - replace the seal;

　　3) Pressure higher than the specified value - reduce the pressure to the specified value;

　　4) The air vent of the wall panel and the oil tank is blocked, causing oil leakage into the chassis - dredge the air vent, install a cock with 2mm aperture in the middle chamber, and open the cock under the wall panel.

　　6、 Roots blower has large vibration

　　Check whether the roots blower is basically stable, whether the coupling is Zhao Zheng, and whether the bearing wear is abnormal. We can deal with the fault of large vibration of Roots blower by strengthening and fastening roots blower, aligning the opposite wheel and replacing the bearing.

　　Roots blower abnormal or vibration causes and solutions:

　　1) The clearance of rolling bearing exceeds the specified value or the bearing seat is worn - replace the bearing or bearing seat;

　　2) The side clearance of the gear is too large, misaligned, and the fixing is not tight - reinstall the gear and ensure the side clearance;

　　3) Impact between impeller and impeller, impeller and casing caused by foreign objects and dust - clean the blower and check whether the casing is damaged;

　　4) Impeller collision due to overload and shaft deformation - check the back pressure, check whether the impeller is centered, and adjust the clearance;

　　5) Friction between impeller and casing inlet caused by overheating - check the filter and back pressure, and increase the clearance between impeller and casing inlet;

　　6) The impeller is out of balance due to dirt or foreign matters - clean the impeller and casing to ensure the working clearance of the impeller;

　　7) Anchor bolts and other fasteners are loose - tighten the anchor bolts and level the base.
