济南厨房排烟工程应用的全过程中，维护非常重要，可以降低常见故障的概率。下面就为大家介绍一下厨房排烟工程的传动链和动滑轮的保养。
In the whole process of the application of Jinan kitchen smoke exhaust project, maintenance is very important, which can reduce the probability of common failures. Now let's introduce the maintenance of the transmission chain and movable pulley of the kitchen smoke exhaust project.
厨房油烟过滤器和排油烟机械的风阻会增加，所以一般水平间距应为15厘米，倾斜度应在2%以上，水平端装有活接头，便于物品的分拣在管线中。如果厨房油烟过滤器是新建的，应尽量放在排烟离心风机前面，这样可以增加排油烟管和离心叶轮的油烟附着力，维护保养可以延长循环时间管道疏通和离心风机。与排风罩相连的立管上应设置排风量保持阀。
The wind resistance of kitchen oil smoke filter and oil smoke exhaust machinery will increase, so the general horizontal spacing should be 15 cm, the inclination should be more than 2%, and the horizontal end is equipped with a flexible joint to facilitate the sorting of items in the pipeline. If the kitchen lampblack filter is newly built, it should be placed in front of the smoke exhaust centrifugal fan as far as possible, so as to increase the lampblack adhesion between the lampblack exhaust pipe and the centrifugal impeller, and the maintenance can extend the cycle time, pipe dredging and centrifugal fan. The riser connected with the exhaust hood shall be provided with an exhaust volume holding valve.
传动链和动带轮维修时，链片不得有裂纹和变形，需要转动灵活。每20段拉伸不超过标准值（8毫米）。传动链销的磨损不应超过原直径的5%，不应有严重的弯曲、疲劳裂纹和腐蚀。如果超过允许条件，则应更换。如果动带轮表面磨损不均匀，两个动带轮直径差超过0.2mm，动带轮表面就会出现台阶或痕迹，危及传动链的正常运转。应该更换。
When the transmission chain and movable pulley are repaired, the chain piece shall not have cracks and deformation, and it needs to rotate flexibly. The tension of every 20 segments shall not exceed the standard value (8 mm). The wear of the drive chain pin should not exceed 5% of the original diameter, and there should be no serious bending, fatigue cracks and corrosion. If the allowable conditions are exceeded, it should be replaced. If the wear on the surface of the movable pulley is uneven, and the diameter difference between the two movable pulleys exceeds 0.2mm, steps or traces will appear on the surface of the movable pulley, endangering the normal operation of the transmission chain. It should be replaced.
检修主、侧辊时，检查主、侧辊磨损痕迹是否均匀。磨损程度沿直径方向，主辊1.0mm，侧辊0.5mm。否则，应更换。维护内外门架时，内外门架应垂直，全长不平行度不超过1mm，应用度为3mm。否则，它应该被恢复。使用磁力检查和敲击检查是否有裂缝。如果是这样，它应该恢复。
When overhauling the main and side rollers, check whether the wear marks of the main and side rollers are uniform. The wear degree is along the diameter direction. The main roll is 1.0mm and the side roll is 0.5mm. Otherwise, replace it. When maintaining the inner and outer door frames, the inner and outer door frames should be vertical, with the overall non parallelism of no more than 1mm and the application degree of 3mm. Otherwise, it should be restored. Use magnetic inspection and knocking to check for cracks. If so, it should be restored.
检查变形或变形。当内弯曲变形全长超过1.5mm，总横向宽度差超过1.5mm，内门架现浇板弯曲变形超过2.0mm时，应予以修正。当整体变形严重，滑轨内部规格超过磨损程度时，应损坏。当内外门架的内外滑轨侧面磨损，台阶达到2mm时，应更换或翻新滑轨。
Check for deformation or deformation. When the total length of the internal bending deformation exceeds 1.5mm, the total transverse width difference exceeds 1.5mm, and the bending deformation of the cast-in-place slab of the internal portal frame exceeds 2.0mm, it should be corrected. When the overall deformation is serious and the internal specification of the slide rail exceeds the wear degree, it should be damaged. When the sides of the inner and outer sliding rails of the inner and outer door frames are worn and the steps reach 2mm, the sliding rails should be replaced or renovated.
The above is about the maintenance of the drive chain and movable pulley of the kitchen smoke exhaust project. If you have a demand for the kitchen smoke exhaust project or equipment, please follow our website http://www.jnqsg.com Check the relevant information!
