一、由人员更换气体增压泵的密封。
1、 The seal of gas Booster pump shall be replaced by personnel.
气液增压泵这种结构简单紧凑的产品，组装起来并不困难，但是需要相关的培训，否则很容易因为组装原因导致产品无法正常运行。这类产品主要由缸筒、储油桶、油缸、活塞、密封件等组成。其中有几十种不同规格尺寸的密封圈，分别用在活塞上、中盖上、前盖上等部位。安装时注意细节，否则容易损坏密封件。建议由人员更换，或联系气液增压泵厂家更换。
The gas-liquid Booster pump, a simple and compact product, is not difficult to assemble, but needs relevant training, otherwise it is easy to cause the product to fail to operate normally due to assembly reasons. This type of product mainly consists of cylinder barrels, oil storage barrels, oil cylinders, pistons, seals, etc. There are dozens of different specifications and sizes of sealing rings used on pistons, middle covers, front covers, and other parts. Pay attention to details during installation, otherwise the seal may be damaged. It is recommended to replace it by personnel or contact the manufacturer of gas-liquid Booster pump for replacement.
二、气动增压泵更换密封前的注意事项
2、 Precautions before replacing seals of pneumatic Booster pump
检查前轴。
Check the front axle.
安装油封前，检查前轴表面是否太粗糙，是否有严重的磕碰。气动增压泵长期运行产生的轴向长拉上。如里轴表面过于干燥、粗糙、不光滑，会使油封揭坏，影响密封性能。如果轴面拆装不当，会造成严重拉伤，油封与轴面贴合有缝，导致漏油。在这种情况下，建议更换新轴，因为轴表面必须有很高的光洁度。

Before installing the oil seal, check if the surface of the front axle is too rough and if there are serious bumps. Long axial pull up caused by long-term operation of pneumatic Booster pump. If the surface of the inner shaft is too dry, rough, or unsmooth, it will cause the oil seal to peel off and affect the sealing performance. If the shaft surface is not disassembled properly, it can cause serious strain, and there is a gap between the oil seal and the shaft surface, leading to oil leakage. In this case, it is recommended to replace the shaft with a new one, as the surface of the shaft must have a high smoothness.
检查轴头。
Check the shaft head.
对于只有金属手刺或边缘的简单轴头，可以用铿力打磨平整，防止安装油封时划伤油封唇目，然后检查油封质量是否有破损、裂纹或油污。如果发现这些不良现象，油封不能使用，必须更换新的。
For simple shaft heads with only metal hand pricks or edges, they can be polished flat with steel force to prevent scratching the oil seal lip when installing the oil seal. Then, check the quality of the oil seal for damage, cracks, or oil stains. If these defects are found, the oil seal cannot be used and must be replaced with a new one.
