　　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.

　　想要精准调整罗茨鼓风机叶轮间隙，首先需明确两大核心间隙类型，这是调整的基础，也是避免出错的关键。其一，径向间隙，指转子与机壳内壁之间的间隙，主要影响气体泄漏量与设备效率，不同压力机型的径向间隙标准不同：低压机型（≤0.5bar）标准间隙为0.15-0.20mm，中压机型（0.5-1bar）为0.20-0.25mm，高压机型（≥1bar）为0.25-0.30mm；其二，轴向间隙，指两转子端面的平行间隙，直接关系到转子啮合稳定性，标准轴向窜动需控制在≤0.05-0.10mm（按机型压力分级），若间隙不当，易出现转子摩擦、齿轮啮合异常等问题。

　　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.

　　塞尺法是目前罗茨鼓风机叶轮间隙调整最常用、最精准的方法，操作流程简洁，无需高端设备，新手经过简单指导即可上手，核心分为“测量-调整-复测”三大步骤，每一步都需严格把控细节，避免误差。第一步，间隙测量，准备0.02-1.00mm规格塞尺组，将塞尺薄片垂直插入间隙处，缓慢移动塞尺，选取阻力最大的位置记录数值，径向间隙需测量12点、3点、6点、9点四个点位，轴向间隙需测量转子两端，确保数据全面准确，避免因单点测量误差导致调整失误。

　　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，精准调整，根据测量数据，分别对径向间隙和轴向间隙进行调整，调整方法需针对性操作，不可盲目调整。径向间隙调整可通过增减轴承座垫片实现，根据测量数值与标准值的差值，精准增减垫片厚度，每调整一次，需手动盘车检查转子转动是否顺畅；轴向间隙调整则通过旋转轴承端盖螺栓，改变轴承轴向位置，同时需同步检查齿轮啮合状态，确保齿轮啮合斑点≥60%接触面，避免因轴向调整影响齿轮传动稳定性，这也是很多新手容易忽视的关键步骤。

　　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，复测校准，调整完成后，需再次用塞尺复测径向、轴向间隙，反复调整直至数值符合对应机型的标准要求，同时手动盘车，确认转子无卡顿、无摩擦异响，方可启动设备试运行。需注意，高压机型调整后需进行24小时跑合监测，前8小时每2小时检查一次振动值，确保间隙稳定，避免设备运行中出现间隙偏移。

　　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，罗茨鼓风机叶轮间隙调整还需规避两大常见误区，这也是保障设备稳定运行的关键。一是盲目调整，未测量直接凭经验增减垫片，导致间隙偏差过大，据统计，这类操作引发的设备故障占比达28%；二是忽视运行后的间隙复测，设备运行一段时间后，因热膨胀、振动等因素，间隙可能出现偏移，建议清洁空气工况下每6000小时检查一次，含尘气体工况每3000小时检查一次，间隙超标20%时需及时调整。

　　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，叶轮间隙调整的精准度直接影响设备运行效率，间隙过大易导致气体泄漏，使设备效率下降5%-10%；间隙过小则会造成转子摩擦，严重时烧毁电机、损坏机壳。对工业企业而言，掌握正确的叶轮间隙调整方法，不仅能降低设备故障发生率，还能延长设备使用寿命，据测算，规范调整叶轮间隙可使罗茨鼓风机使用寿命延长3-5年，每年节省维修成本与能耗支出超万元。

　　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.

　　综上，罗茨鼓风机叶轮间隙调整并非复杂的专业操作，核心在于“精准测量、科学调整、反复复测”，塞尺法作为最实用的调整方法，能有效保障调整精度，适配各类工业场景的运维需求。随着罗茨鼓风机在工业领域的应用日益广泛，规范的间隙调整已成为企业降低运维成本、提升生产效率的重要举措。掌握本文所述的实操技巧，无论是新手还是资深运维人员，都能精准完成叶轮间隙调整，避免因操作失误造成设备损坏，让罗茨鼓风机持续稳定运行，为企业生产保驾护航。

　　Overall, adjusting the clearance of Roots blower impellers is not a complex professional operation. The core lies in "precise measurement, scientific adjustment, and repeated retesting". The feeler gauge method, as the most practical adjustment method, can effectively ensure adjustment accuracy and adapt to the operation and maintenance needs of various industrial scenarios. With the increasing application of Roots blowers in the industrial field, standardized gap adjustment has become an important measure for enterprises to reduce operation and maintenance costs and improve production efficiency.
