　　As the core representative of positive displacement blowers, Roots blowers are widely used in various industrial fields such as sewage treatment, pneumatic conveying, building materials, and chemical industry due to their advantages of stable pressure and constant flow gas transmission. According to the White Paper on the Development of China's Wind Turbine Industry in 2025, the domestic Roots blower market will reach 8.56 billion yuan in 2025, a year-on-year increase of 6.2%, with industrial demand accounting for over 70%. However, many companies have fallen into a fatal misconception in equipment maintenance: neglecting the adjustment of impeller clearance, resulting in abnormal equipment operation. According to industry data statistics, 68% of Roots blower failures are caused by improper impeller clearance, of which 35% directly result in equipment scrap due to incorrect clearance adjustment, with repair costs reaching 40% -60% of the total equipment price. As the core parameter of Roots blower operation, impeller clearance directly determines equipment efficiency and service life. Today, combined with the practical tutorial of plug gauge method, we comprehensively analyze the adjustment techniques of Roots blower impeller clearance, balancing professionalism and operability, helping enterprises avoid operation and maintenance traps and reduce losses.

　　想要合理調(diào)整羅茨鼓風(fēng)機(jī)葉輪間隙，首先需明確兩大核心間隙類型，這是調(diào)整的基礎(chǔ)，也是避免出錯(cuò)的關(guān)鍵。其一，徑向間隙，指轉(zhuǎn)子與機(jī)殼內(nèi)壁之間的間隙，主要影響氣體泄漏量與設(shè)備效率，不同壓力機(jī)型的徑向間隙標(biāo)準(zhǔn)不同：低壓機(jī)型（≤0.5bar）標(biāo)準(zhǔn)間隙為0.15-0.20mm，中壓機(jī)型（0.5-1bar）為0.20-0.25mm，高壓機(jī)型（≥1bar）為0.25-0.30mm；其二，軸向間隙，指兩轉(zhuǎn)子端面的平行間隙，直接關(guān)系到轉(zhuǎn)子嚙合穩(wěn)定性，標(biāo)準(zhǔn)軸向竄動(dòng)需控制在≤0.05-0.10mm（按機(jī)型壓力分級(jí)），若間隙不當(dāng)，易出現(xiàn)轉(zhuǎn)子摩擦、齒輪嚙合異常等問(wèn)題。

　　To accurately adjust the clearance of the Roots blower impeller, it is necessary to first clarify the two core clearance types, which are the basis for adjustment and the key to avoiding errors. Firstly, the radial clearance refers to the gap between the rotor and the inner wall of the casing, which mainly affects the gas leakage rate and equipment efficiency. The radial clearance standards for different pressure models are different: the standard clearance for low-pressure models (≤ 0.5bar) is 0.15-0.20mm, for medium pressure models (0.5-1bar) is 0.20-0.25mm, and for high-pressure models (≥ 1bar) is 0.25-0.30mm; secondly, the axial clearance refers to the parallel clearance between the two rotor end faces, which directly affects the stability of rotor meshing. The standard axial displacement should be controlled within ≤ 0.05-0.10mm (graded according to the pressure of the model). If the clearance is improper, problems such as rotor friction and gear meshing may occur.

　　塞尺法是目前羅茨鼓風(fēng)機(jī)葉輪間隙調(diào)整非常常用、非常合理的方法，操作流程簡(jiǎn)潔，無(wú)需出眾設(shè)備，新手經(jīng)過(guò)簡(jiǎn)單指導(dǎo)即可上手，核心分為“測(cè)量-調(diào)整-復(fù)測(cè)”三大步驟，每一步都需嚴(yán)格把控細(xì)節(jié)，避免誤差。第一步，間隙測(cè)量，準(zhǔn)備0.02-1.00mm規(guī)格塞尺組，將塞尺薄片垂直插入間隙處，緩慢移動(dòng)塞尺，選取阻力非常大的位置記錄數(shù)值，徑向間隙需測(cè)量12點(diǎn)、3點(diǎn)、6點(diǎn)、9點(diǎn)四個(gè)點(diǎn)位，軸向間隙需測(cè)量轉(zhuǎn)子兩端，確保數(shù)據(jù)多維度準(zhǔn)確，避免因單點(diǎn)測(cè)量誤差導(dǎo)致調(diào)整失誤。

　　The feeler gauge method is currently the most commonly used and accurate method for adjusting the clearance of Roots blower impellers. The operation process is simple and does not require high-end equipment. Novices can get started with simple guidance. The core is divided into three steps: "measurement adjustment retest", and each step requires strict control of details to avoid errors. The first step is to measure the gap. Prepare a 0.02-1.00mm gauge set, insert the gauge sheet vertically into the gap, slowly move the gauge, select the position with the highest resistance, and record the value. The radial gap needs to be measured at 12 points, 3 points, 6 points, and 9 points, and the axial gap needs to be measured at both ends of the rotor to ensure comprehensive and accurate data and avoid adjustment errors caused by single point measurement errors.

　　第二步，合理調(diào)整，根據(jù)測(cè)量數(shù)據(jù)，分別對(duì)徑向間隙和軸向間隙進(jìn)行調(diào)整，調(diào)整方法需針對(duì)性操作，不可盲目調(diào)整。徑向間隙調(diào)整可通過(guò)增減軸承座墊片實(shí)現(xiàn)，根據(jù)測(cè)量數(shù)值與標(biāo)準(zhǔn)值的差值，合理增減墊片厚度，每調(diào)整一次，需手動(dòng)盤(pán)車檢查轉(zhuǎn)子轉(zhuǎn)動(dòng)是否順暢；軸向間隙調(diào)整則通過(guò)旋轉(zhuǎn)軸承端蓋螺栓，改變軸承軸向位置，同時(shí)需同步檢查齒輪嚙合狀態(tài)，確保齒輪嚙合斑點(diǎn)≥60%接觸面，避免因軸向調(diào)整影響齒輪傳動(dòng)穩(wěn)定性，這也是很多新手容易忽視的關(guān)鍵步驟。

　　The second step is precise adjustment. Based on the measurement data, adjust the radial clearance and axial clearance separately. The adjustment method should be targeted and not blindly adjusted. Radial clearance adjustment can be achieved by increasing or decreasing the bearing seat gasket. Based on the difference between the measured value and the standard value, the thickness of the gasket can be accurately increased or decreased. Each adjustment requires manual turning to check whether the rotor rotates smoothly; Axial clearance adjustment is achieved by rotating the bearing end cap bolts to change the axial position of the bearing. At the same time, it is necessary to synchronously check the gear meshing status to ensure that the gear meshing spot is ≥ 60% of the contact surface, in order to avoid affecting the stability of gear transmission due to axial adjustment. This is also a key step that many beginners tend to overlook.

　　第三步，復(fù)測(cè)校準(zhǔn)，調(diào)整完成后，需再次用塞尺復(fù)測(cè)徑向、軸向間隙，反復(fù)調(diào)整直至數(shù)值符合對(duì)應(yīng)機(jī)型的標(biāo)準(zhǔn)要求，同時(shí)手動(dòng)盤(pán)車，確認(rèn)轉(zhuǎn)子無(wú)卡頓、無(wú)摩擦異響，方可啟動(dòng)設(shè)備試運(yùn)行。需注意，高壓機(jī)型調(diào)整后需進(jìn)行24小時(shí)跑合監(jiān)測(cè)，前8小時(shí)每2小時(shí)檢查一次振動(dòng)值，確保間隙穩(wěn)定，避免設(shè)備運(yùn)行中出現(xiàn)間隙偏移。

　　The third step is to retest and calibrate. After the adjustment is completed, it is necessary to retest the radial and axial clearances with a feeler gauge and adjust them repeatedly until the values meet the standard requirements of the corresponding model. At the same time, manually turn the rotor to confirm that there is no jamming or friction noise before starting the equipment for trial operation. Please note that after adjusting the high-voltage model, 24-hour running in monitoring is required. The vibration value should be checked every 2 hours for the first 8 hours to ensure stable clearance and avoid clearance deviation during equipment operation.

　　此外，羅茨鼓風(fēng)機(jī)葉輪間隙調(diào)整還需規(guī)避兩大常見(jiàn)誤區(qū)，這也是保障設(shè)備穩(wěn)定運(yùn)行的關(guān)鍵。一是盲目調(diào)整，未測(cè)量直接憑經(jīng)驗(yàn)增減墊片，導(dǎo)致間隙偏差過(guò)大，據(jù)統(tǒng)計(jì)，這類操作引發(fā)的設(shè)備故障占比達(dá)28%；二是忽視運(yùn)行后的間隙復(fù)測(cè)，設(shè)備運(yùn)行一段時(shí)間后，因熱膨脹、振動(dòng)等因素，間隙可能出現(xiàn)偏移，建議清潔空氣工況下每6000小時(shí)檢查一次，含塵氣體工況每3000小時(shí)檢查一次，間隙超標(biāo)20%時(shí)需及時(shí)調(diào)整。

　　In addition, the adjustment of the impeller clearance of Roots blower also needs to avoid two common misconceptions, which are key to ensuring the stable operation of the equipment. One is blind adjustment, directly adding or removing gaskets based on experience without measurement, resulting in excessive gap deviation. According to statistics, equipment failures caused by such operations account for 28%; The second is to ignore the gap retesting after operation. After the equipment has been running for a period of time, the gap may deviate due to factors such as thermal expansion and vibration. It is recommended to check every 6000 hours under clean air conditions and every 3000 hours under dusty gas conditions. If the gap exceeds 20%, it needs to be adjusted in a timely manner.

　　值得注意的是，葉輪間隙調(diào)整的合理度直接影響設(shè)備運(yùn)行效率，間隙過(guò)大易導(dǎo)致氣體泄漏，使設(shè)備效率下降5%-10%；間隙過(guò)小則會(huì)造成轉(zhuǎn)子摩擦，嚴(yán)重時(shí)燒毀電機(jī)、損壞機(jī)殼。對(duì)工業(yè)企業(yè)而言，掌握正確的葉輪間隙調(diào)整方法，不僅能降低設(shè)備故障發(fā)生率，還能延長(zhǎng)設(shè)備使用壽命，據(jù)測(cè)算，規(guī)范調(diào)整葉輪間隙可使羅茨鼓風(fēng)機(jī)使用壽命延長(zhǎng)3-5年，每年節(jié)省維修成本與能耗支出超萬(wàn)元。

　　It is worth noting that the accuracy of adjusting the impeller clearance directly affects the operating efficiency of the equipment. If the clearance is too large, it can easily lead to gas leakage, resulting in a 5% -10% decrease in equipment efficiency; If the gap is too small, it can cause rotor friction, and in severe cases, burn out the motor and damage the casing. For industrial enterprises, mastering the correct method of adjusting impeller clearance can not only reduce equipment failure rates, but also extend equipment service life. According to calculations, standardizing the adjustment of impeller clearance can extend the service life of Roots blowers by 3-5 years, saving maintenance costs and energy consumption expenditures of over 10000 yuan per year.

　　綜上，羅茨鼓風(fēng)機(jī)葉輪間隙調(diào)整并非復(fù)雜的專業(yè)操作，核心在于“合理測(cè)量、科學(xué)調(diào)整、反復(fù)復(fù)測(cè)”，塞尺法作為非常實(shí)用的調(diào)整方法，能有效保障調(diào)整精度，適配各類工業(yè)場(chǎng)景的運(yùn)維需求。隨著羅茨鼓風(fēng)機(jī)在工業(yè)領(lǐng)域的應(yīng)用日益廣泛，規(guī)范的間隙調(diào)整已成為企業(yè)降低運(yùn)維成本、提升生產(chǎn)效率的重要舉措。掌握本文所述的實(shí)操技巧，無(wú)論是新手還是資深運(yùn)維人員，大多能合理完成葉輪間隙調(diào)整，避免因操作失誤造成設(shè)備損壞，讓羅茨鼓風(fēng)機(jī)持續(xù)穩(wěn)定運(yùn)行，為企業(yè)生產(chǎn)保駕護(hù)航。
