羅茨鼓風(fēng)機(jī)日常保養(yǎng)常識(shí)

　　一、定期更換羅茨風(fēng)機(jī)油液

　　羅茨鼓風(fēng)機(jī)是生產(chǎn)企業(yè)常用的設(shè)備，這涉及到了三葉羅茨鼓風(fēng)機(jī)的保養(yǎng)問(wèn)題。如果保養(yǎng)得當(dāng)，會(huì)大大延長(zhǎng)使用壽命以及運(yùn)行的穩(wěn)定性。潤(rùn)滑油經(jīng)過(guò)一段時(shí)間的使用，會(huì)發(fā)生性能老化和泄露消耗，因此需要及時(shí)進(jìn)行補(bǔ)充或更換，我整理了一下?lián)Q油和保養(yǎng)的方法。

　　羅茨鼓風(fēng)機(jī)*基礎(chǔ)的保養(yǎng)就是換油，一般羅茨風(fēng)機(jī)累計(jì)運(yùn)行1000小時(shí)后就要進(jìn)行換油。采用220#齒輪油進(jìn)行更換，油位應(yīng)在油鏡的一半，切忌過(guò)高或過(guò)低。

　　另要注意的是，換油的時(shí)候要將油箱里的油先排空后再注入新油。不要在舊油的基礎(chǔ)上添加，這樣時(shí)間長(zhǎng)了會(huì)導(dǎo)致油箱的油太臟、太稠。從而影響羅茨鼓風(fēng)機(jī)的運(yùn)作。

　　除了油位需要日常檢查注意外，皮帶松緊度、空氣濾芯的檢查也同樣重要。每半月對(duì)濾芯進(jìn)行徹底清掃根據(jù)使用情況，至少每半年更換一次濾芯 。羅茨鼓風(fēng)機(jī)的所有部位，哪怕再小，也是至關(guān)重要的。切不可因?yàn)橥祽泻鲆?，而因小失大?/p>

　　羅茨鼓風(fēng)機(jī)各機(jī)型的油量隨時(shí)都可以看到齒輪側(cè)油鏡，停機(jī)時(shí)可以在中線之間保持油面。機(jī)油水平低于中間位置時(shí)，應(yīng)及時(shí)添加潤(rùn)滑油。如果油位高于中間位置，則有可能發(fā)生油溫高、尾氣噴射、氣體漏油等。

　　軸承潤(rùn)滑脂要用指定的潤(rùn)滑耐熱油脂(通用鋰基潤(rùn)滑脂ZL-3/二硫化鉬)，累計(jì)運(yùn)行150小時(shí)加一次(3個(gè)月內(nèi)不足150小時(shí)也必須用黃油槍打入)，加注時(shí)必須保證黃油確實(shí)已經(jīng)加入。

　　加注方法：用油脂槍加油脂到規(guī)定量。(添加油脂要在剛停機(jī)后進(jìn)行)補(bǔ)充油脂到完畢后運(yùn)行15分鐘，確認(rèn)多余的油脂從風(fēng)機(jī)端蓋的放油槽中流出。停機(jī)后擦掉多余的油脂。

　　一般的羅茨風(fēng)機(jī)的使用條件有以下幾點(diǎn)：

　　1.進(jìn)口氣體溫度不大于35℃ 。

　　2.氣體中固體微粒含量不大于100m3，微塵**顆粒尺寸應(yīng)不大于0.05毫米。

　　3.煤氣的含煤焦油指標(biāo)應(yīng)符合TJ28-78城市煤氣規(guī)范設(shè)計(jì)的規(guī)定 。

　　4.軸承溫度**不超過(guò)85℃ 。

　　5.潤(rùn)滑油溫度**不超過(guò)65℃ 。

　　6.風(fēng)機(jī)上的所示壓力不得超過(guò)標(biāo)牌所規(guī)定的升壓范圍，否則必須停車(chē)檢查系統(tǒng)中進(jìn)口是否堵塞，進(jìn)排氣口閥門(mén)是否全部關(guān)閉，風(fēng)機(jī)中的靜動(dòng)件是否發(fā)生摩擦等其他一些問(wèn)題，并采取相應(yīng)措施。

　　二、檢查羅茨鼓風(fēng)機(jī)固定螺栓

　　1.檢查各部位的緊固情況及定位銷(xiāo)是否有松動(dòng)現(xiàn)象;

　　2.羅茨鼓風(fēng)機(jī)機(jī)體內(nèi)部是否有漏水、漏油現(xiàn)象;

　　3.羅茨鼓風(fēng)機(jī)機(jī)體內(nèi)部不能有結(jié)構(gòu)、生銹和剝落現(xiàn)象存在;

　　4.羅茨鼓風(fēng)機(jī)拆卸機(jī)器前，應(yīng)對(duì)機(jī)器各配合尺寸進(jìn)行測(cè)量，作好記錄，并在零部件上作好標(biāo)記，以保證裝配后保持原來(lái)配合要求;

　　5.羅茨鼓風(fēng)機(jī)的軸承與齒輪采用飛濺潤(rùn)滑，須保證潤(rùn)滑油與上述潤(rùn)滑油性能相當(dāng)以利于齒輪與軸承正常運(yùn)行，油箱中的油量在停車(chē)時(shí)要保證在油標(biāo)中線以上，潤(rùn)滑油要定期更換，**次啟動(dòng)工作200小時(shí)、換**次油，以后每半年換油。注入新油前應(yīng)用中性煤油把油箱和齒輪清洗干凈;

　　6.注意潤(rùn)滑及冷卻情況是否正常，注意潤(rùn)滑的質(zhì)量。經(jīng)常傾聽(tīng)羅茨鼓風(fēng)機(jī)運(yùn)行有無(wú)雜聲。注意機(jī)組是否在不符合規(guī)定的工況下運(yùn)行;

　　7.羅茨鼓風(fēng)機(jī)的過(guò)載，有時(shí)不是立即顯示出來(lái)的，所以要注意進(jìn)、排氣壓力，軸承溫度和電動(dòng)機(jī)電流的增加趨勢(shì)，籍以判斷機(jī)器是否運(yùn)行正

　　8.維護(hù)檢修應(yīng)按具體使用情況擬定合理的維修制度，按期進(jìn)行，并作好記錄，建議每年大修一次，并更換軸承和有關(guān)易損件。

　　羅茨鼓風(fēng)機(jī)維護(hù)保養(yǎng)對(duì)風(fēng)機(jī)長(zhǎng)時(shí)間正常運(yùn)轉(zhuǎn)至關(guān)重要，我們?cè)谌粘１ｐB(yǎng)羅茨鼓風(fēng)機(jī)過(guò)程中應(yīng)注意風(fēng)機(jī)潤(rùn)滑及冷卻情況是否正常，注意潤(rùn)滑的質(zhì)量，經(jīng)常傾聽(tīng)遞羅茨鼓風(fēng)機(jī)運(yùn)轉(zhuǎn)過(guò)程中，有無(wú)異常情況、異常振動(dòng)以及異常響動(dòng)，及時(shí)根據(jù)異常針對(duì)性檢修維護(hù)。

　　三、開(kāi)機(jī)關(guān)機(jī)注意事項(xiàng)

　　1.由于風(fēng)機(jī)出口不暢通，風(fēng)不通，壓力增加，電動(dòng)機(jī)形成過(guò)載浪涌，管道被阻塞，然后設(shè)備的電流表增加。電流過(guò)載的不正確操作也會(huì)在操作期間引起問(wèn)題。例如，如果設(shè)備倒轉(zhuǎn)，則閥門(mén)未完全打開(kāi)，此操作可能導(dǎo)致發(fā)動(dòng)機(jī)立即燃燒。

　　2.在操作中，必須按照規(guī)定進(jìn)行操作，禁止引起不必要的問(wèn)題。潤(rùn)滑油如果缺少設(shè)備潤(rùn)滑油，風(fēng)機(jī)將繼續(xù)無(wú)油運(yùn)行。葉輪將發(fā)生碰撞，齒輪將磨損，然后增加電動(dòng)機(jī)的負(fù)載。它只會(huì)增加發(fā)動(dòng)機(jī)的負(fù)載，從而加速損失。渦輪本身的問(wèn)題是工廠中存在質(zhì)量問(wèn)題。安裝風(fēng)機(jī)時(shí)，許多組件組合不良，將導(dǎo)致分類(lèi)沖突。

　　3.根據(jù)羅茨鼓風(fēng)機(jī)故障分析的準(zhǔn)備，羅茨鼓風(fēng)機(jī)制造商的零件維護(hù)和更換規(guī)則，確定維修地點(diǎn)和規(guī)模，并準(zhǔn)備可能需要更換的零件。根據(jù)零件的結(jié)構(gòu)準(zhǔn)備適當(dāng)?shù)臋z查元件和測(cè)量工具。根據(jù)羅茨鼓風(fēng)機(jī)的質(zhì)量，制定了審查計(jì)劃。

　　4.實(shí)施安全措施。刪除預(yù)防措施時(shí)，必須標(biāo)記重要部件的尺寸和設(shè)備的方向，以便在組裝過(guò)程中恢復(fù)檢查標(biāo)記，以免卡住。例如，測(cè)量并記錄幾個(gè)楔塊的厚度，測(cè)量并記錄轉(zhuǎn)子各個(gè)部分的間隙，并對(duì)主齒輪和從動(dòng)件以及喉嚨中的相應(yīng)符號(hào)進(jìn)行匯總。

　　5.在安裝羅茨鼓風(fēng)機(jī)之前，清潔并查看將要使用的零件。對(duì)于已拆卸的零件，必須保護(hù)加工外觀并按照某些規(guī)則進(jìn)行放置。同一零件必須放置在一起，例如外殼，填料函和同一零件的調(diào)節(jié)墊圈。缺少的零件必須包含在專(zhuān)用設(shè)備中。匹配的應(yīng)用程序必須存儲(chǔ)在一起。

　　四、總結(jié)

　　羅茨風(fēng)機(jī)保養(yǎng)的常識(shí)和方法是：

　　1、開(kāi)機(jī)前請(qǐng)一定要先打開(kāi)手動(dòng)放空閥，檢查油箱機(jī)油是否已到油位線，用手盤(pán)動(dòng)風(fēng)機(jī)是否靈活，如果盤(pán)動(dòng)靈活，再按啟動(dòng)，然后慢慢將放空閥關(guān)閉，使三葉羅茨鼓風(fēng)機(jī)達(dá)到滿(mǎn)負(fù)荷(切記不能超載運(yùn)行)。關(guān)機(jī)時(shí)請(qǐng)一定先打開(kāi)放空閥，然后再按斷開(kāi)。這樣正常操作使用才能延錦工機(jī)使用壽命。

　　2、請(qǐng)定時(shí)定期派人檢查風(fēng)機(jī)油箱油位如發(fā)現(xiàn)機(jī)油低于油標(biāo)中間位置，即請(qǐng)馬上補(bǔ)充。如發(fā)現(xiàn)油標(biāo)和放油塞還有油箱結(jié)合處有漏油跡象則必須及時(shí)更換修復(fù)。請(qǐng)每半年完全更換一次機(jī)油。油標(biāo)很臟無(wú)法看清機(jī)油時(shí)則需馬上把油標(biāo)清洗干凈，以防誤導(dǎo)油箱機(jī)油油位而燒壞齒輪，如機(jī)油明顯很臟時(shí)也應(yīng)及時(shí)更換。

　　3、如果軸承是使用油脂潤(rùn)滑的，則每三個(gè)月至半年必須補(bǔ)充一次，每年必須更換一次風(fēng)機(jī)高溫油脂。(注：三葉羅茨鼓風(fēng)機(jī)均使用純正的二硫化鉬3號(hào)鋰基脂或風(fēng)機(jī)專(zhuān)用高溫潤(rùn)滑脂。)風(fēng)機(jī)運(yùn)行時(shí)須檢查油箱溫度、振動(dòng)及聲音，檢查進(jìn)排氣壓力電流表指數(shù)等是否正常。

　　4、請(qǐng)確保風(fēng)機(jī)房空氣流通順暢、降溫措施完備，注意風(fēng)機(jī)房的清潔工作，以免由于風(fēng)機(jī)吸入灰塵太多而堵塞進(jìn)氣過(guò)濾消聲器或卡死風(fēng)機(jī)。則必須定期清洗過(guò)濾器內(nèi)的濾芯(海綿或過(guò)濾無(wú)防材料)和進(jìn)氣消聲器內(nèi)的灰垢，無(wú)法清洗或清洗不干凈時(shí)請(qǐng)及時(shí)更換空氣過(guò)濾器濾芯。

　　Common sense of daily maintenance of Roots blower

　　1、 Change the oil of Roots blower regularly

　　Roots blower is a common equipment in production enterprises, which involves the maintenance of three leaf roots blower. If properly maintained, the service life and operation stability will be greatly extended. After a period of use, the lubricating oil will have performance aging and leakage consumption, so it needs to be supplemented or replaced in time. I sorted out the methods of oil change and maintenance.

　　The most basic maintenance of Roots blower is to change the oil. Generally, the oil should be changed after the roots blower has operated for 1000 hours. Use 220 # gear oil for replacement, and the oil level should be half of the oil mirror. Do not be too high or too low.

　　It should also be noted that when changing the oil, drain the oil in the oil tank first and then inject new oil. Don't add it on the basis of old oil, as the oil in the tank will be too dirty and thick after a long time. Thus affecting the operation of Roots blower.

　　In addition to the daily inspection of oil level, the inspection of belt tightness and air filter element is also important. Thoroughly clean the filter element every half a month, and replace the filter element at least every half a year according to the service condition. All parts of Roots blower, no matter how small, are also crucial. We must not lose much because of laziness and neglect.

　　The oil quantity of each model of Roots blower can be seen at any time from the oil mirror on the gear side, and the oil level can be maintained between the center lines when the blower is stopped. When the oil level is lower than the middle position, add lubricating oil in time. If the oil level is higher than the middle position, high oil temperature, tail gas injection, gas leakage, etc. may occur.

　　The bearing grease shall be lubricated with the specified lubricating heat-resistant grease (general lithium grease zl-3/ molybdenum disulfide), and it shall be added once after 150 hours of cumulative operation (it must also be injected with a grease gun if it is less than 150 hours within 3 months). When filling, it must be ensured that the grease has indeed been added.

　　Filling method: add grease to the specified amount with a grease gun. (adding grease should be carried out just after the shutdown) run for 15 minutes after adding grease, and confirm that the excess grease flows out of the oil drain tank of the fan end cover. Wipe off excess grease after shutdown.

　　The general operating conditions of Roots blower are as follows:

　　1. The inlet gas temperature shall not be greater than 35 ℃.

　　2. The content of solid particles in the gas shall not be greater than 100m3, and the maximum particle size of micro dust shall not be greater than 0.05 mm.

　　3. The coal tar index of the gas shall comply with the provisions of tj28-78 urban gas specification design.

　　4. The maximum bearing temperature shall not exceed 85 ℃.

　　5. The maximum temperature of lubricating oil shall not exceed 65 ℃.

　　6. The pressure indicated on the fan shall not exceed the pressure rise range specified on the label, otherwise it must stop to check whether the inlet of the system is blocked, whether all the inlet and outlet valves are closed, and whether the static parts in the fan have friction and other problems, and take corresponding measures.

　　2、 Check the fixing bolts of Roots blower

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

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

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

　　4. 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;

　　5. The bearings and gears of Roots blower adopt splash lubrication. It is necessary to ensure that the performance of the lubricating oil is equivalent to that of the above lubricating oil, so as to facilitate the normal operation of the gears and bearings. The oil volume in the oil tank should be above the centerline of the oil standard when stopping. The lubricating oil should be changed regularly. The oil should be changed for the first time after the first start-up for 200 hours, and then every half a year. Clean the oil tank and gear with neutral kerosene before injecting new oil;

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

　　7. The overload of Roots blower is sometimes 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 is running correctly

　　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.

　　Routine maintenance site of Roots blower

　　The maintenance of Roots blower is very important for the normal operation of the blower for a long time. In the process of daily maintenance of Roots blower, we should pay attention to whether the lubrication and cooling of the blower are normal, pay attention to the quality of lubrication, often listen to whether there are abnormal conditions, abnormal vibration and abnormal sound during the operation of Roots blower, and timely repair and maintain according to the abnormalities.

　　3、 Precautions for startup and shutdown

　　1. Because the fan outlet is blocked, the wind is blocked, the pressure increases, the motor forms overload surge, the pipeline is blocked, and then the ammeter of the equipment increases. Incorrect operation of current overload can also cause problems during operation. For example, if the equipment is reversed and the valve is not fully opened, this operation may cause the engine to burn immediately.

　　2. During the operation, the operation must be carried out in accordance with the regulations, and unnecessary problems are prohibited. If there is a lack of equipment lubricating oil, the fan will continue to run without oil. The impeller will collide, the gear will wear, and then increase the load of the motor. It will only increase the load on the engine, thereby accelerating the loss. The problem of the turbine itself is the quality problem in the factory. When installing the fan, many components are poorly combined, which will lead to classification conflict.

　　3. According to the preparation of Roots blower fault analysis, the parts maintenance and replacement rules of Roots blower manufacturer, determine the maintenance location and scale, and prepare the parts that may need to be replaced. Prepare appropriate inspection elements and measuring tools according to the structure of the parts. According to the quality of Roots blower, the review plan is formulated.

　　4. Implement safety measures. When deleting preventive measures, the size of important parts and the direction of the equipment must be marked, so that the inspection mark can be restored during the assembly process to avoid jamming. For example, measure and record the thickness of several wedges, measure and record the clearance of each part of the rotor, and summarize the corresponding symbols in the main gear, follower and throat.

　　5. Before installing roots blower, clean and check the parts to be used. For disassembled parts, the machining appearance must be protected and placed according to certain rules. The same parts must be placed together, such as housing, stuffing box and adjusting washer of the same part. The missing parts must be included in the special equipment. Matching applications must be stored together.

　　4、 Summary

　　Common sense and methods of Roots blower maintenance are:

　　1. Before starting the machine, be sure to open the manual vent valve first, check whether the oil in the oil tank has reached the oil level line, and check whether the fan is flexible by hand. If it is flexible, press start, and then slowly close the vent valve to make the three leaf roots blower reach full load (remember not to overload operation). Please be sure to open the vent valve first and then press to disconnect when shutting down. In this way, the service life of Jingong machine can be extended after normal operation.

　　2. Please send someone regularly to check the oil level of the fan oil tank. If the oil level is lower than the middle position of the oil scale, please replenish it immediately. If there is any sign of oil leakage at the junction of the oil pointer, the oil drain plug and the oil tank, it must be replaced and repaired in time. Please change the oil completely every six months. If the oil mark is dirty and the oil cannot be seen clearly, the oil mark should be cleaned immediately to prevent misleading the oil level of the oil tank and burning the gear. If the oil is obviously dirty, it should also be replaced in time.

　　3. If the bearing is lubricated with grease, it must be supplemented every three months to half a year, and the high-temperature grease of the fan must be replaced once a year. (Note: all three leaf roots blowers use pure molybdenum disulfide No. 3 lithium grease or special high-temperature lubricating grease for fans.) When the fan is running, check the temperature, vibration and sound of the oil tank, and check whether the inlet and exhaust pressure, ammeter index, etc. are normal.

　　4. Please ensure that the air circulation in the fan room is smooth and the cooling measures are complete. Pay attention to the cleaning of the fan room to avoid blocking the intake filter silencer or blocking the fan due to too much dust inhaled by the fan. The filter element (sponge or filter without anti-corrosion material) in the filter and the ash dirt in the intake muffler must be cleaned regularly. If it cannot be cleaned or cannot be cleaned, please replace the air filter element in time.

　　5. Please check and adjust the belt tension regularly and carry out a small maintenance, including checking whether the fan bearings and gears are excessively worn or damaged in the early stage; Clean the oil tank, air chamber and sealing device of the fan; Correct the clearance of each part of the fan; Find and solve the problems in time to avoid more serious damage to the fan.
