一、调整前的准备工作

　　1、 Preparation work before adjustment

　　1.工具与材料：备好塞尺、螺丝刀、调整垫片等必备工具，且保证这些工具处于良好状态。

　　1. Tools and materials: Prepare necessary tools such as feeler gauges, screwdrivers, and adjusting washers, and ensure that these tools are in good condition.

　　2.操作规范：确保设备已停止运行，并切断电源，防止出现意外情况。

　　2. Operation specifications: Ensure that the equipment has stopped running and cut off the power to prevent unexpected situations.

　　3.转子状态检查：查看转子的运行状况，包括转动是否平稳、有无异常声响等，若发现异常，需及时停机检查并排除故障。

　　3. Rotor status inspection: Check the operating condition of the rotor, including whether it rotates smoothly, whether there are any abnormal sounds, etc. If any abnormalities are found, stop the machine in a timely manner for inspection and troubleshooting.

　　二、调整的具体步骤

　　2、 Specific steps for adjustment

　　1.测量初始间隙：运用塞尺等工具，精确测量转子与机壳之间的初始间隙，为后续调整提供参照。

　　1. Measure initial clearance: Use tools such as feeler gauges to accurately measure the initial clearance between the rotor and the casing, providing reference for subsequent adjustments.

　　2.调整垫片厚度：依据测量结果和风机的性能标准，挑选合适厚度的调整垫片。通过增加或减少垫片的数量，逐步对转子间隙进行调整。

　　2. Adjust the thickness of the gasket: Based on the measurement results and the performance standards of the fan, select the appropriate thickness of the adjusting gasket. Gradually adjust the rotor clearance by increasing or decreasing the number of shims.

　　3.反复测量与调整：调整垫片后，再次测量转子间隙，保证间隙值符合规定要求。若间隙值仍不达标，需继续调整垫片厚度，直至达到理想的间隙值。

　　3. Repeated measurement and adjustment: After adjusting the gasket, measure the rotor clearance again to ensure that the clearance value meets the specified requirements. If the gap value still does not meet the standard, it is necessary to continue adjusting the thickness of the gasket until the ideal gap value is reached.

　　4.安装与试运行：调整完毕后，重新安装转子和壳体，仔细检查各个部件的位置，确保它们都准确安装在相应位置。之后对罗茨风机的运行情况进行测试，检查噪音、振动和温度等参数，确认其能够正常运转。

　　4. Installation and trial operation: After adjustment, reinstall the rotor and housing, carefully check the position of each component, and ensure that they are accurately installed in their respective positions. Afterwards, the operation of the Roots blower will be tested to check parameters such as noise, vibration, and temperature to confirm that it can operate normally.

　　三、相关注意要点

　　3、 Related precautions

　　1.精度要求：转子间隙的调整对精度要求较高，因此在测量和调整过程中，要使用合适的测量工具，确保操作准确无误。

　　1. Accuracy requirements: The adjustment of rotor clearance requires high accuracy, so suitable measuring tools should be used during the measurement and adjustment process to ensure accurate operation.

　　2.数据记录：调整过程中，需详细记录每次调整的垫片厚度和间隙值，以便后续进行分析和优化。

　　2. Data recording: During the adjustment process, it is necessary to record in detail the thickness and clearance values of each adjusted gasket for subsequent analysis and optimization.

　　3.定期检查：转子间隙的调整并非一劳永逸，而应定期开展。建议根据设备的使用情况和性能要求，制定合理的检查与调整周期。

　　3. Regular inspection: The adjustment of rotor clearance is not a one-time solution, but should be carried out regularly. It is recommended to establish a reasonable inspection and adjustment cycle based on the usage and performance requirements of the equipment.

　　4.专业协助：对于复杂的调整工作，或者经验不足的人员，建议寻求专业人员的指导或帮助。

　　4. Professional assistance: For complex adjustment work or inexperienced personnel, it is recommended to seek guidance or assistance from professionals.

　　四、具体的调整技巧

　　4、 Specific adjustment techniques

　　1.叶轮间隙调整：将叶轮转到规定位置，调整驱动齿轮与轴的对齐程度，然后安装齿轮挡圈、止动垫片和锁紧螺母。若叶轮转动不顺畅，可借助铜棒轻轻敲击叶轮间隙部位进行调整。

　　1. Impeller clearance adjustment: Rotate the impeller to the specified position, adjust the alignment between the drive gear and the shaft, and then install the gear retaining ring, stop washer, and locking nut. If the impeller does not rotate smoothly, you can use a copper rod to gently tap the gap between the impellers for adjustment.

　　2.轴向间隙调整：组装墙板时，先保证轴向总间隙符合要求，再通过前墙板上的调节螺钉调整叶轮轴的位置，确保两端间隙分配均匀。

　　2. Axial clearance adjustment: When assembling the wall panel, first ensure that the total axial clearance meets the requirements, and then adjust the position of the impeller shaft through the adjustment screws on the front wall panel to ensure even distribution of clearance at both ends.

　　3.垫片厚度确定：可采用测量法（用深度游标卡尺测量间隙值）或加试法（用假轴套试加垫片并测量间隙值）来确定垫片的厚度。

　　3. Determination of gasket thickness: The thickness of the gasket can be determined using measurement method (measuring the gap value with a depth vernier caliper) or additional testing method (testing the gasket with a fake shaft sleeve and measuring the gap value).
